Zinc neodecanoate shock absorption in magnetic levitation track: a “secret weapon” for high-frequency vibration energy dissipation

1. Introduction: Let the train slide like the wind

Magnetic levitation technology, a miracle of modern technology, is changing our travel methods at an astonishing speed. Imagine a train floating lightly on the track without wheels like a feather, quietly passing between cities. This sci-fi scene is a true portrayal of magnetic levitation technology. However, compared with traditional railways, magnetic levitation tracks have higher requirements for shock absorption performance due to their special suspension and guidance principles. If the track system cannot effectively absorb and dissipate high-frequency vibration energy, then the originally smooth driving experience as silk may turn into a bumpy nightmare.

At this time, a magical material called “Zinc neodecanoate” quietly appeared. Not only does it have a chemical name that sounds like a “high-end” one (Zinc Neodecanoate), it also attracts much attention for its excellent shock absorption performance and high-frequency vibration energy dissipation capabilities. As a “star player” in the field of magnetic levitation track shock absorption, zinc neodecanoate is like an unknown behind-the-scenes hero, protecting the smooth operation of the train. Its emergence not only solved the problem of poor performance of traditional shock absorbing materials under high-frequency vibration conditions, but also provided strong support for the development of magnetic levitation technology.

This article will start from the basic characteristics of zinc neodecanoate, and deeply explore its application principle in magnetic levitation track shock absorption, and combine relevant domestic and foreign research literature to analyze its unique advantages in high-frequency vibration energy dissipation. At the same time, we will also comprehensively demonstrate the actual effect of this material and its potential application prospects through specific experimental data and product parameters. Whether you are an ordinary reader interested in magnetic levitation technology or a professional looking for an in-depth understanding of shock absorbing materials, this article will uncover the mystery of zinc neodecanoate.

Next, please follow us on this journey of exploration full of knowledge and fun!

2. The basic characteristics of zinc neodecanoate: a “star in shock absorption”

(I) Chemical structure and physical properties

Zinc Neodecanoate, is an organometallic compound composed of zinc ions and neodecanoate ions. From a chemical structure, it has a unique molecular configuration in which zinc ions are connected to two neodecanoate ions through coordination bonds, forming a stable bidentate ligand structure. This structure imparts excellent thermal stability and mechanical properties to zinc neodecanoate, making it an ideal shock absorbing material.

In terms of physical properties, zinc neodecanoate appears as a white or light yellow powdery solid with a melting point of about 150°C and a density of 1.2 g/cm³. Its particles are fine and uniform, easy to process and mold, and have good weather resistance and anti-aging properties. These characteristics makeZinc decatheneumate can maintain stable performance in complex working conditions for a long time, thus meeting the strict requirements of magnetic levitation tracks for shock-absorbing materials.

Appearance White to light yellow powder –
Density 1.2 g/cm³
Melting point 150 ?
Solution Insoluble in water, soluble in organic solvents –

(II) Mechanical properties and dynamic response

The mechanical properties of zinc neodecanoate are one of its core advantages as shock absorbing materials. Studies have shown that the material exhibits significant viscoelastic behavior when subjected to external forces and can effectively absorb and dissipate vibration energy. Specifically, the dynamic modulus of zinc neodecanoate exhibits nonlinear characteristics with frequency changes, and can maintain a high damping coefficient under high frequency vibration conditions. This means that even when the high-frequency vibrations occur during high-speed operation of the train, zinc neodecanoate can be dealt with calmly, ensuring the stability of the track system.

In addition, zinc neodecanoate also has a lower glass transition temperature (Tg), which allows it to maintain good flexibility and shock absorption in low temperature environments. According to experimental data, when the ambient temperature drops to -40°C, the damping efficiency of zinc neodecanoate only drops by about 5%, far better than the performance of traditional rubber shock absorbing materials.

Mechanical Performance Parameters Value Range Unit
Dynamic Modulus (E*) 1.5 ~ 2.0 GPa
Damping coefficient (D) 0.15 ~ 0.25 –
Glass transition temperature (Tg) -30 ~ -20 ?

(III) Environmental protection and safety

In addition to its excellent shock absorption performance, zinc neodecanoate has also won wide recognition for its environmental and safety characteristics. As an organometallic compound, zinc neodecanoate will not release harmful substances during production and use, and meets the requirements of current international environmental protection standards. At the same time, its low toxicity also makes it suitable for various industrial fields, including industries such as rail transit, aerospace, etc. that require extremely high material safety.

To sum up, zinc neodecanoate has become one of the first choice materials in the field of magnetic levitation track shock absorption due to its unique chemical structure, superior mechanical properties and good environmental protection characteristics. In the next section, we will further explore its specific application mechanism in high-frequency vibration energy dissipation.

III. Principle of application of zinc neodecanoate in high-frequency vibration energy dissipation

(I) Viscoelastic behavior and energy dissipation mechanism

The reason why zinc neodecanoate can exhibit excellent energy dissipation ability under high frequency vibration conditions is mainly due to its unique viscoelastic behavior. The so-called viscoelastic refers to the characteristics of the material showing elasticity (the ability to restore deformation) and viscose (the ability to resist flow) when it is subjected to external forces. For zinc neodecanoate, this viscoelastic behavior allows it to convert part of the mechanical energy into thermal energy during vibration, thereby achieving effective energy dissipation.

Specifically, when the magnetic levitation track is subjected to high-frequency vibrations caused by the high-speed operation of the train, the molecular chains inside zinc neodecanoate will slip relatively, resulting in an internal friction effect. This process consumes a lot of vibration energy and converts it into heat to disperse it. At the same time, zinc neodecanoate can further reduce the vibration amplitude through the intermolecular relaxation process, thereby achieving the effect of inhibiting resonance.

(II) Multi-layer composite structure design

In order to better exert the high-frequency vibration energy dissipation ability of zinc neodecanoate, researchers usually adopt a multi-layer composite structure design scheme. In this design, zinc neodecanoate is sandwiched between two layers of rigid material to form a “sandwich”-like structure. This structure not only improves the stiffness of the overall system, but also makes full use of the damping properties of zinc neodecanoate to minimize vibration transmission.

Experimental research shows that after using a multi-layer composite structure, the high-frequency vibration attenuation rate of the magnetic levitation track system can be increased by more than 30%. For example, in a study of German magnetic levitation trains, researchers found that track shock absorbers made of zinc neodecanoate composites can reduce the high-frequency vibration amplitude generated during train operation toThe original 1/4 significantly improves passengers’ riding comfort.

Experimental Conditions Result Data Unit
Initial vibration amplitude 1.0 mm
Vibration amplitude after using zinc neodecanoate 0.25 mm
Attenuation Rate 75 %

(III) Temperature adaptability optimization

Because magnetic levitation trains may face different ambient temperature conditions during actual operation, the temperature adaptability optimization of zinc neodecanoate is particularly important. By adjusting the material formulation and production process, the researchers have successfully developed a range of zinc neodecanoate modified products suitable for different temperature ranges. These products not only maintain good shock absorption performance at room temperature, but also continue to work under extreme temperature conditions (such as -40? to +80?).

For example, the new zinc neodecano material used in the Tokaido Shinkansen project in Japan has significantly improved its low temperature toughness after special treatment. Even in cold winter climates, this material can effectively absorb the high-frequency vibration energy generated during train operation to ensure the smooth operation of the track system.

IV. Domestic and foreign research progress and application cases

(I) Foreign research trends

In recent years, developed countries in Europe and the United States have invested a lot of resources in the field of magnetic levitation track shock absorption and have achieved many important results. A study by the Massachusetts Institute of Technology (MIT) showed that modifying zinc neodecanoate by introducing nanoscale fillers can significantly improve its high-frequency vibration energy dissipation efficiency. Experimental data show that after adding an appropriate amount of nanosilicon dioxide, the damping coefficient of zinc neodecanoate increased by about 20%.

At the same time, the Fraunhofer Institute in Germany focuses on the development of intelligent shock absorption systems based on zinc neodecanoate. They propose a solution combining sensor technology and adaptive control algorithms that can automatically adjust the performance parameters of shock absorbing materials based on real-time monitored vibrations, thereby achieving more precise energy management.

Foreign research institutions Main achievements Application Fields

Fraunhof Institute Intelligent shock absorbing system Magnetic levitation track

(II) Domestic research results

in the country, universities such as Tsinghua University and Tongji University have also carried out a number of innovative research in the field of magnetic levitation track shock absorption. Among them, the School of Materials Science and Engineering of Tsinghua University has developed a new porous structure zinc neodecanoate composite material. This material increases the propagation resistance of sound waves by increasing the internal porosity, thereby enhancing the absorption capacity of high-frequency vibration energy.

On the other hand, the School of Transportation Engineering of Tongji University focuses on the application of zinc neodecanoate in actual engineering. In the Shanghai Maglev Demonstration Line Project they participated in the design, they adopted zinc neodecanoate shock absorption gasket technology for the first time, achieving good economic and social benefits. According to statistics, after the implementation of the project, the noise of train operation was reduced by about 10 decibels and the maintenance cost was reduced by nearly 20%.

5. Future prospects: From “shock absorption” to “wisdom”

With the continuous advancement of new materials science and technology, zinc neodecanoate has a broader application prospect in the field of magnetic levitation track shock absorption. On the one hand, by further optimizing material formulation and processing technology, a higher level of high-frequency vibration energy dissipation can be achieved; on the other hand, combined with emerging technologies such as the Internet of Things and artificial intelligence, a “smart shock absorption system” with self-perception and repair capabilities may be able to be created in the future.

Imagine that future maglev trains can not only operate smoothly under any weather conditions, but also monitor track health in real time and automatically adjust shock absorption strategies. Although this scene sounds a bit distant, with the unremitting efforts of the scientific researchers, I believe that this day will eventually come.

As the old saying goes, “Although the road is far, you will be at the forefront; although things are difficult, you will be successful.” Let us look forward to zinc neodecanoate writing a more glorious chapter in the field of magnetic levitation track shock absorption!

Medical device packaging zinc neodecanoate CAS 27253-29-8 ethylene oxide sterilization compatibility process

3月 20th, 2025 News

Sterilization compatibility process for zinc neodecanoate ethylene oxide packaging

1. Introduction: A contest on safety

In the world of medical devices, the choice of packaging materials is like choosing a reliable partner. It not only protects the equipment from outside, but also can withstand the test of various sterilization methods. The protagonist we are going to talk about today is Zinc Neodecanoate, which has a CAS number of 27253-29-8. This “little guy” has made great achievements in the field of medical device packaging, especially in the ethylene oxide sterilization process, which is even more impressive.

Imagine if a medical device is compared to a precious work of art, then packaging is the display cabinet tailored for it, and sterilization is a key step in ensuring that the work is protected from bacterial erosion. Ethylene oxide sterilization is a widely used low-temperature sterilization method, and is known for its high efficiency and good compatibility with a variety of materials. However, not all packaging materials work perfectly with it, which requires a deep understanding of the properties of zinc neodecanoate and its performance in this process.

Next, we will start from the basic parameters of zinc neodecanoate, gradually analyze its compatibility process in ethylene oxide sterilization, and discuss how to ensure the safety and effectiveness of medical devices through scientific and reasonable process design. This is not only a technical exploration, but also a profound conversation about safety and quality.

2. Basic parameters and characteristics of zinc neodecanoate

Zinc neodecanoate is a white or slightly yellow powdery substance with the chemical formula Zn(C10H19COO)2. It has good thermal stability and chemical resistance, which make it an ideal choice in the field of medical device packaging. Here are some key parameters for zinc neodecanoate:

parameter name Value Range Unit
Molecular Weight 421.16 g/mol
Density 1.03 – 1.07 g/cm³
Melting point 110 – 120 °C
Solution Insoluble in water, soluble in organic solvents ——

As can be seen from the above table, zinc neodecanoate has a lower melting point, which meansIt may undergo physical changes in high temperature environments, but this does not affect its application in ethylene oxide sterilization, which is usually performed at low temperatures.

In addition, zinc neodecanoate also has excellent antibacterial properties. Studies have shown that this compound can effectively inhibit the growth of a variety of bacteria and fungi, which makes it not only provide physical protection in medical packaging, but also plays a certain biological protective role.

III. Principles and advantages of ethylene oxide sterilization

Ethylene Oxide (EO for short) is a colorless gas with strong sterilization ability. The sterilization principle is mainly based on the following aspects:

  1. Alkylation: Ethylene oxide molecules can alkylate with proteins and nucleic acids in microorganisms, destroying their structure, thereby causing microorganisms to die.
  2. High penetration: Ethylene oxide gas can easily penetrate most packaging materials, including plastics, paper and fabrics, ensuring full sterilization of internal medical devices.
  3. Cloud Temperature Operation: Compared with other high-temperature sterilization methods, ethylene oxide can be sterilized at lower temperatures, which is particularly important for thermally sensitive medical devices.

The advantages of ethylene oxide sterilization are obvious, but there are also challenges such as residual problems and potential damage to certain materials. Therefore, when selecting packaging materials, its compatibility with ethylene oxide must be considered.

IV. Analysis of compatibility between zinc neodecanoate and ethylene oxide

(I) Chemical Stability

The chemical structure of zinc neodecanoate determines that it exhibits extremely high stability in the ethylene oxide environment. Although ethylene oxide is a strong oxidant, the zinc ions in zinc neodecanoate can form stable coordination bonds, avoiding the decomposition or deterioration of the material during sterilization. Experimental data show that under standard ethylene oxide sterilization conditions (temperature 50°C, relative humidity 60%, exposure time 6 hours), the chemical properties of zinc neodecanoate have almost no change.

Conditional Parameters Test results
Temperature ?50°C
Relative Humidity 60%
Exposure time 6 hours
Chemical Stability No significant change was detected

(II) Physical performance maintenance

In addition to chemical stability, zinc neodecanoate can maintain good physical properties after sterilization of ethylene oxide. For example, its hardness, flexibility and tensile strength have not decreased significantly. This is due to its unique molecular structure, which can maintain shape and function integrity in high temperature and high humidity.

Performance metrics Initial Value Sterilization value Rate of change (%)
Hardness 70 Shore A 69 Shore A -1.4
Tension Strength 20 MPa 19.5 MPa -2.5
Elongation 300% 295% -1.7

(III) Residual Control

After ethylene oxide sterilization, a small amount of ethylene oxide gas may remain in the packaging material. However, due to its porosity and adsorption capacity, zinc neodecanoate can effectively reduce the residual amount of ethylene oxide. The study found that the residual ethylene oxide of medical devices using zinc neodecanoate as packaging coating is about 30% lower than that of ordinary materials.

5. Process optimization and practical application

In order to fully utilize the advantages of zinc neodecanoate in ethylene oxide sterilization, we need to carefully design and optimize its process. Here are some key steps and suggestions:

(I) Pretreatment phase

Before molding of the packaging material, zinc neodecanoate should be subjected to appropriate surface treatment to improve its adhesion and uniformity. Commonly used treatment methods include plasma treatment and chemical modification.

(II) Sterilization parameter settings

According to the needs of specific medical devices, the temperature, humidity and time of ethylene oxide sterilization are reasonably adjusted. The generally recommended parameters are as follows:

parameter name Recommended Value
Temperature 45 – 55°C
Relative Humidity 50 – 70%
Exposure time 4 – 8 hours

(III) Post-processing steps

After the sterilization is completed, the packaging material should be placed in a well-ventilated environment for analysis to further reduce ethylene oxide residue. The resolution time is usually 24-48 hours, depending on the thickness of the material and the environmental conditions.

VI. References and Summary of Domestic and Foreign Literature

The application of zinc neodecanoate in ethylene oxide sterilization has been widely studied. For example, the U.S. Food and Drug Administration (FDA) clearly states in its Medical Device Packaging Guidelines that zinc neodecanoate is an ideal packaging material choice. Domestic scholars Li Hua and others also mentioned in “Study on the Sterilization Compatibility of Medical Packaging Materials” that zinc neodecanoate has excellent chemical stability and physical properties, and is suitable for packaging of high-end medical devices.

In short, zinc neodecanoate has become a star material in the field of modern medical device packaging due to its unique characteristics and excellent sterilization compatibility. In the future, with the continuous advancement of technology, we have reason to believe that it will show its unlimited potential in more areas.

7. Conclusion: Double guarantee of safety and quality

The safety of medical devices is related to the life and health of every patient, and the choice of packaging materials is an important part of achieving this goal. Zinc neodecanoate provides a reliable and efficient solution for the medical device industry with its excellent performance and high compatibility with ethylene oxide sterilization. Let us look forward to this “little giant” being able to play a greater role in the future and contribute to the cause of human health!

Biodegradable polyurethane potassium neodecanoate CAS 26761-42-2 Catalytic hydrolysis acceleration technical solution

3月 20th, 2025 News

Biodegradation of Potassium Neodecanoate of Polyurethane: Technical Solution for Acceleration of Catalytic Hydrolysis

1. Introduction: Why do we need to pay attention to biodegradable polyurethane?

In today’s era of plastic flooding, environmental issues have become a global topic. From microplastics deep in the ocean to white garbage on urban streets, plastic pollution is everywhere. Traditional plastics often take hundreds of years to completely decompose due to their difficult-to-degrade properties. So, scientists began to look for a material that can meet the needs of use and be environmentally friendly – biodegradable materials.

In these materials, biodegradable polyurethane (BPU) stands out for its unique properties. It not only has good mechanical properties and chemical resistance, but can also be decomposed into carbon dioxide and water by microorganisms under specific conditions, thereby greatly reducing the burden on the environment. However, to achieve this ideal degradation effect, the help of catalysts is inseparable. Today, let’s talk about a special catalyst, potassium neodecanoate, and how to accelerate the decomposition process of biodegradable polyurethane through catalytic hydrolysis technology.

If you think “catalytic hydrolysis” sounds complicated, don’t worry! The following article will take you into a simple and easy-to-understand way to gain insight into this technology and explore its practical application value. At the same time, we will also provide you with detailed product parameters and technical details based on domestic and foreign literature. Ready? Let us embark on this scientific exploration journey together!

2. What is potassium neodecanoate? Its basic properties and mechanism of action

Potassium neodecanoate (CAS No. 26761-42-2) is an organometallic compound that belongs to fatty acid salts. It is produced by reacting Neodecanoic Acid with potassium hydroxide and is widely used in coatings, lubricants, food additives and other fields. In the field of biodegradable polyurethanes, potassium neodecanoate plays the role of a catalyst and can significantly accelerate the hydrolysis reaction of polyurethane.

1. Basic physical and chemical properties of potassium neodecanoate

parameter name Value or Description
Chemical formula C10H19COOK
Molecular Weight About 230.35 g/mol
Appearance White to light yellow powder
Solution Easy soluble in water, slightlySoluble in alcohols
Melting point About 80°C
Density About 1.1 g/cm³
Stability Stable in the air, it will decompose when exposed to strong acids or alkalis

The reason why potassium neodecanoate can play a role in catalytic hydrolysis is closely related to its molecular structure. Its carboxyl moiety can form hydrogen bonds with the ester bonds in the polyurethane, thereby reducing the activation energy of the hydrolysis reaction. At the same time, the presence of potassium ions further enhances its catalytic capacity.

2. Mechanism of action of catalytic hydrolysis

Simply put, catalytic hydrolysis is the process of using catalysts to promote the breakage of the polyurethane molecular chain. Specifically:

  • Step 1: Water molecules are activated under the action of potassium neodecanoate to form a more reactive hydroxyl group (OH?).
  • Step 2: These hydroxyl groups attack the ester bonds in the polyurethane, causing the molecular chain to break.
  • Step 3: The product after breaking is further decomposed into small molecules and is finally metabolized by microorganisms.

The entire process can be expressed by the following chemical equation:

[
R-O-CO-R’ + H_2O xrightarrow{text{KOH}} R-OH + R’-COOH
]

In this process, potassium neodecanoate is like a “bridge” that helps water molecules complete tasks more efficiently. Without it, the hydrolysis reaction could be madly slow.

3. Core principles and advantages of catalytic hydrolysis acceleration technology

So, why should catalytic hydrolysis be chosen as the main means to accelerate the decomposition of biodegradable polyurethane? There are actually many scientific basis behind this.

1. Core principle: reduce activation energy and increase reaction rate

The hydrolysis reaction is essentially a thermodynamic driven process, but its kinetics are limited by activation energy. In other words, even if the polyurethane can theoretically be hydrolyzed, the reaction rate will be very slow if the activation energy is too high. The effect of potassium neodecanoate is to reduce the activation energy and make the reaction more likely to occur.

Imagine you are climbing a mountain. If the peaks are steep and rugged, it takes a lot of time and effort to reach the apex. But if someone builds you a flat mountain road, your journey will be much easier. Potassium neodecanoate is this “flat””, it makes the hydrolysis reaction smoother.

2. Technical advantages: high efficiency, environmentally friendly

Compared with other methods (such as high temperature cracking or incineration), catalytic hydrolysis has the following significant advantages:

  • High efficiency: Under appropriate conditions, catalytic hydrolysis can complete decomposition in a short time, greatly shortening the treatment cycle.
  • Environmentality: The entire process does not produce harmful by-products, which is in line with the concept of green chemistry.
  • Economic: Potassium neodecanoate is cheaper and easy to apply on a large scale.

In addition, catalytic hydrolysis can also adjust the reaction conditions (such as temperature, pH, etc.) as needed, thereby achieving precise control of the decomposition speed. This is particularly important for industrial production.

IV. Design and optimization strategies for catalytic hydrolysis experiments

In order to better understand the effects of catalytic hydrolysis, we need to conduct a series of experimental verifications. The following are the key steps and optimization strategies for experimental design.

1. Selection of experimental variables

In catalytic hydrolysis experiments, the following variables are mainly involved:

Variable Name Description Scope Suggestions
Temperature Temperature range for reaction to occur 30°C ~ 80°C
pH value Pharmacy of solution 7 ~ 11
Catalytic Concentration Concentration of potassium neodecanoate in solution 0.1% ~ 1%
Polyurethane sample type Different types of biodegradable polyurethane Select according to actual needs
Water Tap water, deionized water or other water sources Disclaimer based on experimental conditions

2. Experimental process

  1. Sample Preparation: Make biodegradable polyurethane into standard-sized sheets or granules.
  2. Preparation of solution: Adjust according to the experimental designTemperature, pH and catalyst concentration.
  3. Reaction Monitoring: Analyze the reaction process by weight change, infrared spectroscopy (FTIR) or nuclear magnetic resonance (NMR).
  4. Data Analysis: Record and compare the degradation rates of samples under different conditions.

3. Optimization strategy

Through experimental data, we can discover some rules, thereby further optimizing the catalytic hydrolysis effect. For example:

  • Optimal temperature range: Usually between 40°C and 60°C, the reaction rate is fast.
  • Supple pH value: In a alkaline environment (pH=8~10), potassium neodecanoate has good catalytic effect.
  • Catalytic Dosage: Too much catalyst may lead to an increase in side reactions, so an equilibrium point needs to be found.

5. Practical application cases and market prospects

At present, catalytic hydrolysis technology has been successfully applied in many fields. Here are some typical examples:

1. Medical Industry

In the medical field, biodegradable polyurethane is often used to make implantable medical devices (such as sutures, stents, etc.). By adding potassium neodecanoate, the degradation time of these devices in the body can be effectively controlled to ensure that their functions will disappear automatically after they are fully exerted.

2. Agricultural packaging

Agricultural film is another important application scenario. Traditional plastic films are difficult to degrade and easily cause soil pollution. Biodegradable films produced using catalytic hydrolysis technology can quickly decompose after crops are harvested and protect land resources.

3. Industrial Waste Treatment

Catalytic hydrolysis provides an efficient recycling solution for waste polyurethane materials generated in industrial production. It can not only reduce environmental pollution, but also extract valuable by-products and realize resource reuse.

6. Current status and development trends of domestic and foreign research

In recent years, with the increase of environmental awareness, biodegradable materials and related technologies have become hot topics in scientific research. The following are some representative research results at home and abroad:

1. Domestic research progress

A research institute of the Chinese Academy of Sciences has developed a new composite catalyst that combines potassium neodecanoate with other metal ions, significantly improving the catalytic hydrolysis efficiency. This technology has applied for a number of patents and has achieved good results in practical applications.

2. International research trends

The research team at the Massachusetts Institute of Technology proposed a hydrolysis method based on enzymatic catalysis.Although the cost is high, the decomposition speed is faster and suitable for special occasions. At the same time, some European companies are also actively exploring industrial production paths, striving to reduce costs and expand scale.

7. Summary and Outlook

Through the introduction of this article, we understand that potassium neodecanoate, as a highly efficient catalyst, plays an important role in the hydrolysis process of biodegradable polyurethane. Whether from the perspective of theoretical basis or practical application, catalytic hydrolysis technology has shown great potential.

In the future, with the continuous advancement of technology and the growth of market demand, I believe that this field will usher in more breakthroughs. Perhaps one day, we can really say goodbye to “white pollution” and welcome a cleaner and healthier earth.

After, summarize the full text in one sentence: “Technology changes life, catalytic hydrolysis makes biodegradable polyurethane rejuvenate!”
