Polyurethane composite anti-heartburn agent: an innovator in glass product quality

In the modern industry, glass, as an ancient and vibrant material, has long surpassed traditional windows and utensils. From smartphone screens to solar panels, from car windshields to high-end optical instruments, glass products are permeating every aspect of our lives at an amazing speed. However, with the continuous escalation of market demand, the challenges faced by traditional glass manufacturing processes are becoming increasingly prominent. Among them, glass surface defects have always been one of the important factors affecting product quality. Especially during the high-temperature melting process, due to the presence or insufficient melting of impurities in the raw materials, it is easy to cause defects such as bubbles and stripes on the glass surface, which not only affects the aesthetics, but also may reduce the functionality and durability of the product.

To solve this problem, polyurethane composite anti-heartburn agents came into being. With its excellent performance, this new additive has become a key tool for improving the quality of glass products. It effectively reduces bubble generation by optimizing the chemical reaction path during glass melting and significantly improves the flatness and finish of the glass surface. In addition, the product also has good thermal stability and environmental protection characteristics, and can achieve a comprehensive improvement in glass quality without changing the original production process. It can be said that the emergence of polyurethane composite anti-heartburn agents has brought revolutionary breakthroughs to the glass industry, making high-quality glass products no longer out of reach.

This article will discuss from multiple angles such as the basic principles, product parameters, application scenarios, and domestic and foreign research status of polyurethane composite anti-heartburn agents. By deeply analyzing its technical characteristics and actual effects, readers can fully understand how this innovative material helps glass products move into a new era of higher quality. At the same time, the article will combine rich data and examples to show its wide application prospects in different fields, providing valuable reference for relevant practitioners.

1. Definition and classification of polyurethane composite anti-heartburn agent

Polyurethane composite anti-heartburn agent is a multifunctional additive specially designed to improve quality problems in glass production. It is mainly composed of polyurethane substrates and other functional additives, which can effectively inhibit surface defects caused by chemical reactions or physical phenomena in the melting stage of glass. According to its mechanism of action and composition differences, polyurethane composite anti-heartburn agents can be divided into the following categories:

  1. Physical anti-living agent
    This type of anti-heartburn agent mainly reduces surface defects by regulating the fluidity of the glass molten liquid. For example, certain polyurethane materials of certain structures can form a protective film at high temperatures to prevent pits caused by cracking when bubbles float. The advantage of this type of product is that it is simple to operate and is suitable for ordinary glass products with low chemical requirements.

  2. Chemical anti-living agent
    Chemical anti-centrifuge agents focus on participating in and optimizing chemical reactions during glass melting. They usually contain active ingredients that promote impurities decomposition or accelerate gas escape, thereby significantly reducing the possibility of bubble residue. This type of anti-heartburn agent is suitable for the manufacture of special glasses with high precision requirements, such as optical glass or electronic grade glass.

  3. Comprehensive anti-living agent
    Comprehensive anti-centrifuge agents combine physical and chemical mechanisms, which can not only reduce bubble generation by changing the chemical environment, but also improve surface quality by adjusting melt flow. Due to its versatility and adaptability, this type of anti-heartburn agent has gradually become the mainstream choice in the market.

Table 1: Main categories and characteristics of polyurethane composite anti-heartburn agents

Category Main Functions Applicable scenarios Advantages
Physical Improve melt flow and reduce surface pits Ordinary flat glass, architectural glass Easy to operate and low cost
Chemical type Participate in chemical reactions to reduce bubble generation Optical glass, electronic grade glass Efficiently remove tiny bubbles
Comprehensive Effect both physical and chemistry at the same time Multi-purpose glass, such as automotive glass, photovoltaic glass Comprehensive functions and strong adaptability

The reason why polyurethane composite anti-heartburns stand out in the glass industry is largely due to their unique molecular structure design. By combining additives with different functions with polyurethane substrates, it can flexibly respond to various complex production conditions and meet diverse product needs. Whether it is high-end optical glass that pursues extreme transparency or large-scale industrial production that focuses on economics, polyurethane composite anti-heartburn agents can provide an ideal solution.

2. The mechanism of action of polyurethane composite anti-heartburn agent

The key reason why polyurethane composite anti-heartburn agent can significantly improve the quality of glass products is its unique mechanism of action. This process involves complex interactions at multiple levels, including physical adsorption, chemical reactions, and interface regulation. The following is a specific analysis of its core mechanism of action:

(I) Physical adsorption and isolation effects

Impurities in raw materials during the melting process of glass(such as carbonate, sulfate, etc.) will decompose and produce gases at high temperatures, which will gradually accumulate and form bubbles. If the bubbles cannot be discharged in time, they will solidify on the inside or surface of the glass after cooling, resulting in obvious defects. The polyurethane composite anti-heartburn agent forms a dense protective film on the surface of the molten liquid through its unique molecular structure. This film has excellent physical adsorption capability and can effectively prevent bubbles from contacting directly with the glass surface, thereby avoiding pits or other damage caused by bubble burst.

Specifically, long-chain molecules in polyurethane substrates can quickly diffuse to the surface of the molten liquid and firmly adhere to the glass substrate by van der Waals force. At the same time, the functional additives in the anti-heartburn agent will further enhance the stability and toughness of the membrane layer, allowing it to maintain integrity under high temperature environments. This physical isolation effect not only reduces the impact of air bubbles on the glass surface, but also effectively delays the migration rate of other harmful substances (such as metal ions) to the inside of the glass, thereby reducing the probability of deep defects.

(Bi) Chemical catalysis and reaction optimization

In addition to physical adsorption, polyurethane composite anti-heartburn agent also actively participates in the glass melting process through chemical reactions. The catalyst components contained in it can significantly accelerate the decomposition rate of impurities in the raw material, so that the generated gas can quickly escape without retention in the molten liquid. For example, when calcium carbonate decomposes to form carbon dioxide, acidic functional groups in the anti-heartburn agent will neutralize it, reducing the solubility of carbon dioxide and prompting it to be released from the molten liquid more quickly.

In addition, anti-cardiosaccharides can also optimize the entire chemical reaction environment by regulating the pH of the molten liquid. Studies have shown that an appropriate pH range can help improve the stability of the silicate network and reduce stress concentration caused by local overheating or uneven cooling. This chemical regulation not only improves the overall uniformity of the glass, but also provides better basic conditions for its subsequent processing.

(III) Interface regulation and liquidity improvement

The flow performance of glass molten liquid is one of the important factors that determine the quality of the final product. If the molten liquid is too viscous, it may cause the bubbles to be difficult to discharge smoothly; while too low viscosity may easily cause problems such as droplet separation. Polyurethane composite anti-centrifuge agent cleverly balances the viscosity and fluidity of the molten liquid through interface regulation technology, ensuring that it always maintains an ideal state throughout the entire production process.

The surfactant component in the anti-heartburn agent can significantly reduce the interfacial tension of the molten liquid, thereby making it easier for the bubbles to detach from the liquid surface and escape into the air. At the same time, its special molecular structure can effectively prevent the occurrence of layering or agglomeration of molten liquid, ensuring the consistency and continuity of the glass matrix. This interface regulation capability is particularly important for the production of large or ultra-thin glass products, as it can significantly reduce thickness deviations and optical distortion problems caused by uneven flow.

(IV) Temperature stability and long-term protection

It is worth mentioning thatPolyurethane composite anti-living agents also exhibit extremely high temperature stability. Even under extreme conditions up to 1500°C or above, its molecular structure can still be kept intact and will not decompose or fail. This excellent thermal stability allows the anti-cardiocarciner to continue to function until the glass is completely cooled and molded. Compared with traditional single-function additives, the long-term protective properties of polyurethane composite anti-heartburn agents undoubtedly won it higher ratings.

To sum up, polyurethane composite anti-centrifuge agent successfully solved the common bubbles, stripes and other surface defects in glass production through the synergistic effect of various mechanisms such as physical adsorption, chemical catalysis, interface regulation and temperature stability. Its emergence not only greatly improves the quality of glass products, but also brings new directions of technological change to the entire industry.

III. Product parameters and technical indicators of polyurethane composite anti-heartburn agent

In order to better understand the actual performance of polyurethane composite anti-heartburn agents and their applicability in different scenarios, we need to have an in-depth understanding of its specific technical parameters and product specifications. The following will be explained in detail from multiple dimensions such as appearance, physical properties, chemical characteristics, and usage conditions.

(I) Appearance shape

Polyurethane composite anti-heartburn agents are usually present in powder or granular form for easy storage and transportation. Its colors are mostly light gray or white, with no obvious odor, and have good dispersion. This design not only facilitates users to add it evenly to the glass raw materials, but also effectively avoids the impact of production efficiency due to agglomeration or precipitation.

(II) Physical properties

Table 2 shows the main physical properties parameters of polyurethane composite anti-heartburn agent:

parameter name Unit Value Range
Density g/cm³ 0.8-1.2
Particle Size ?m 10-100
Melting point ? 120-150
Hydragonism % ?0.5

It can be seen from the table that the moderate density of the product not only ensures its good suspension in the molten liquid, but does not settle to the bottom due to excessive weight. The particle size distribution range is narrow, which helps to achieve a more uniform dispersion effect. In addition, its low moisture absorption rate also ensures the stability of the product in humid environments and extends the shelf life.

(III) Chemical Characteristics

As a functional additive, the chemical properties of polyurethane composite anti-heartburn agents are crucial. The following is a summary of its main chemical parameters:

parameter name Description
pH value Neutral or weakly alkaline (7-9)
Active ingredient content ?95%
Impurity content ?0.1%
Cream residue ?0.05%

These parameters show that polyurethane composite anti-heartburn agents have high purity and low impurity content, which can greatly reduce contamination on finished glass products. In particular, the level of control of combustion residues is much lower than industry standards, which means it leaves almost no trace in high temperature environments, thus ensuring absolute cleanliness of the glass surface.

(IV) Conditions of use

In practical applications, polyurethane composite anti-heartburn agent needs to meet certain conditions of use before it can fully exert its effectiveness. The following are the recommended usage parameters:

parameter name Recommended Value
Add ratio 0.1%-0.5% by weight
Using temperature 1400-1600?
Stirring time ?10 minutes
Cooling rate Contained at 50-100?/hour

It should be noted that the specific addition ratio and use temperature should be adjusted appropriately according to the type of target product and production process. For example, for optical glass with high precision requirements, it is recommended to use a higher additive ratio to ensure good results; for ordinary building glass, the amount used can be appropriately reduced to save costs.

Through the detailed introduction of the above parameters, we can clearly recognize the superiority of polyurethane composite anti-heartburn agents in performance and their flexibility in actual operation. It is these precise designs and strict controls that make it an indispensable and important tool in the modern glass manufacturing industry.

Polyurethane composite anti-heartburn agent improves the fineness of stone processing

3月 16th, 2025 News

1. Introduction: The past and present life of stone processing

In the long journey of human civilization, stone, as a natural material, has always played an important role. From stone tools from ancient times to high-end decorative materials in modern architecture, stone processing technology has undergone thousands of years of evolution and innovation. However, behind this seemingly simple polishing and cutting, there are countless technical challenges and craftsmanship problems. Among them, the stubborn disease of edge burning is like a lurking time bomb, which always threatens the quality and value of stone products.

When we enter a modern stone processing factory, we will find that every piece of stone undergoes a rigorous processing process. From the initial rough grinding to the final polishing, every step requires precise control and professional skills. However, it is in this critical processing step that the edge burning problem caused by high temperatures often becomes the main culprit that affects product quality. This phenomenon not only damages the appearance aesthetics of the stone, but more seriously, it will reduce its physical properties and make it difficult for the product to meet the standards required by customers.

In order to solve this industry pain point, polyurethane composite anti-heartburn agents came into being. This innovative product is like a dedicated guardian, which can effectively absorb and disperse heat during the stone processing process to prevent edge burning caused by overheating. Through its unique molecular structure design, it organically combines multiple functional components to form a solid protective barrier. Whether it is marble, granite or artificial stone, it can achieve a more refined processing effect under its protection.

This article will conduct in-depth discussion on the application principles, technical parameters and actual effects of polyurethane composite anti-heartburn agents in stone processing, and combine with relevant domestic and foreign research literature to comprehensively analyze its important role in improving the fineness of stone processing. At the same time, we will also demonstrate the excellent performance of this product in actual production through specific case analysis, and provide scientific and reasonable application suggestions for stone processing enterprises.

2. Analysis of edge burning phenomenon in stone processing

In the field of stone processing, edge burning is a common quality problem, and its causes are complex and diverse. First of all, from a physical perspective, the friction heat generated during stone processing is the main reason for the edge burning phenomenon. When diamond abrasives operate at high speed, they will undergo violent friction with the surface of the stone, generating a large amount of heat. If these heat cannot be lost in time, it will accumulate locally on the surface of the stone, causing a sharp increase in temperature.

Secondly, the difference in the thermal expansion coefficient of the stone itself also aggravates the occurrence of edge burning. Different kinds of stone have different mineral composition and structural properties, which make them exhibit different expansion behaviors when heated. For example, marble is mainly composed of calcium carbonate, and its thermal expansion coefficient is relatively small; while granite contains various mineral components such as feldspar and quartz, and its thermal expansion coefficient is large and uneven. This difference causes the stone to easily generate internal stress during heating, which can cause cracks or deformation.

In addition, improper setting of processing parameters can also induce feverOne of the important factors of edge phenomenon. Such as excessive cutting speed, excessive feeding or insufficient coolant supply will aggravate heat accumulation. Especially under dry processing conditions, the lack of effective cooling measures will make the temperature more likely to exceed the heat resistance limit of the stone. Studies have shown that when the surface temperature of the stone exceeds 150?, obvious edge burning may occur.

To understand the impact of edge burning more intuitively, we can compare it to a “stone beauty disaster”. Imagine that a originally smooth and flat stone surface suddenly appears with erythema or cracks similar to sunburn. This not only destroys the aesthetics of the stone, but may also seriously affect its mechanical properties and service life. The hardness of the burning edge area usually decreases significantly, which is prone to problems such as edge collapse and angle drop, which brings many inconveniences to subsequent processing.

More importantly, the edge burning phenomenon will also cause direct damage to the commercial value of the stone. In the high-end stone market, any minor defects can lead to a decline in product grade or even rejection. Therefore, how to effectively prevent and control the edge burning phenomenon has become a key issue that needs to be solved in the stone processing industry. This also provides an important practical background for the research and development and application of new anti-heartburn agents.

3. The core advantages and working principle of polyurethane composite anti-heartburn agent

The reason why polyurethane composite anti-heartburn agents can stand out in the field of stone processing is due to its unique molecular structure design and excellent functional characteristics. This product uses advanced nanodispersion technology to perfectly combine the polyurethane matrix with a variety of functional fillers to form a composite system that combines heat conduction, heat absorption and thermal stability. Its core advantages are mainly reflected in the following aspects:

First, from the perspective of chemical structure, polyurethane composite anti-heartburn agent adopts a special cross-link modification process to form a three-dimensional network structure. This structure gives the product excellent thermal stability, allowing it to maintain stable performance under high temperature environments. At the same time, the doped nanoscale oxide particles can significantly improve the thermal conductivity of the product and promote rapid heat loss. According to laboratory test data, the thermal conductivity of the product can reach 0.4 W/(m·K), which is much higher than the level of traditional coolant.

Secondly, this product has a unique phase change energy storage function. By introducing specific phase change materials, a large amount of heat can be absorbed and stored within a certain temperature range, and then slowly released, thereby effectively controlling the surface temperature of the stone. This phase transition process is like an intelligent temperature control system that can provide continuous and stable cooling during critical machining stages. Studies have shown that when using polyurethane composite anti-heartburn agent, the surface temperature of the stone can be reduced by 30-40?, significantly reducing the probability of edge burning.

Again, the product also has excellent lubricating properties. Its molecular chain contains specific polar groups, which can form a stable lubricating film between the stone and the abrasive tool, reducing friction resistance and reducing heat generation. At the same time, this lubricating film can also effectively prevent wear of abrasive tools.Extend its service life. Experimental data show that after using this product, the life of the abrasive tool can be extended by more than 20%.

After

, the polyurethane composite anti-living agent also has the characteristics of environmental protection and safety. All the raw materials are made of biodegradable materials, which do not contain any toxic and harmful substances, and meet the requirements of green and environmental protection. At the same time, the product has good chemical stability and is not easy to react with other chemicals, ensuring the safety of use.

In order to more intuitively demonstrate its superior performance, the following table lists the main technical parameters of polyurethane composite anti-heartburn agent and traditional coolant:

Technical Indicators Polyurethane composite anti-living agent Traditional coolant
Thermal conductivity (W/m·K) 0.4 0.15
Phase Transformation Temperature Range (°C) 80-120 –
Luction coefficient ?0.1 ?0.3
Thermal Stability (°C) ?200 ?120
Biodegradation rate (%) ?95 ?50

The implementation of these superior performances is due to the synergistic effect of multiple key technical components in the product formulation. These include high-efficiency thermal conductivity fillers, phase change energy storage materials, lubricating additives, and environmentally friendly additives.

4. Domestic and foreign research results and practice verification

The research and development and application of polyurethane composite anti-heartburn agents have received widespread attention from the academic and industry circles at home and abroad. In recent years, many scientific research institutions and enterprises have conducted in-depth research on their performance optimization, application effects, etc., and have achieved fruitful results. The following is an overview of some representative research results:

A study system from the Polytechnic University of Milan, Italy compared the performance of different types of coolants in stone processing. The research team used infrared thermal imager to monitor the temperature changes on the surface of stone in real time. The results showed that when using polyurethane composite anti-centrifugal agent, the temperature fluctuation range of the surface of stone is significantly smaller than that of other types of coolants. Especially under high load processing conditions, the temperature control advantages of this product are more significant. The study also found that after using this product, the microscopic morphology of the stone surface is more uniform, and the crystallineThe degree of particle damage was significantly reduced.

Researchers from the Massachusetts Institute of Technology in the United States have focused on the phase change energy storage mechanism of polyurethane composite anti-heartburn agents. They analyzed the thermal behavior characteristics of the product through differential scanning calorimetry (DSC) and found that its phase change temperature range is highly consistent with the temperature interval during stone processing. This allows the product to play a great role in critical moments when cooling is needed. In addition, the researchers have developed an artificial intelligence-based temperature prediction model that can accurately predict the cooling effect of products under different processing conditions.

The research team from the Department of Materials Science and Engineering of Tsinghua University in China systematically evaluated the long-term stability of polyurethane composite anti-heartburn agents. Through accelerated aging tests and practical application tests, it was confirmed that the product can maintain more than 95% of its initial performance after one year of continuous use. The study also found that appropriately adjusting the crosslink density in product formula can improve its anti-pollution performance to a certain extent and extend its service life.

A industrial application study by the Fraunhofer Institute in Germany shows that the application effect of polyurethane composite anti-heartburn agents on automated stone processing production lines is particularly outstanding. Through comparative testing of three different production lines, it was found that after using this product, the frequency of equipment shutdown and maintenance was reduced by 40%, and the product pass rate was increased by 25%. Especially for some stone processing of special materials, such as artificial stone and super hard stone, its advantages are more obvious.

The China National Academy of Building Materials Sciences has carried out a large-scale field test project involving more than a dozen large stone processing enterprises across the country. The test results show that after using polyurethane composite anti-heartburn agent, the average energy consumption was reduced by 15% and the processing efficiency was improved by 20%. It is particularly worth noting that this product shows good adaptability under both wet and dry processing conditions, meeting the diversified needs of different enterprises.

These research results not only verify the excellent performance of polyurethane composite anti-heartburn agents, but also provide an important reference for further optimization and promotion of products. Through continuous technological innovation and practical exploration, this product is gradually improving its functional characteristics and bringing more possibilities to the stone processing industry.

5. Analysis of practical application cases and effects

In order to more intuitively demonstrate the practical application effect of polyurethane composite anti-heartburn agent, we selected two typical stone processing cases for detailed analysis. These two cases represent different types of stone processing scenarios, fully demonstrating the wide applicability and excellent performance of the product.

The first case comes from a large granite processing plant located in Quanzhou, Fujian. The factory mainly produces granite slabs for high-end building decoration, but often encounters serious edge burning problems during processing. Especially when cutting large-size sheets with thicknesses exceeding 5cm, the traditional cooling method cannot effectively control the temperature, resulting in the yield rate being maintained at around 75%. The situation has improved significantly since the introduction of polyurethane composite anti-heartburn agent last year. Through field testing,Under the same processing conditions, the surface temperature of the stone was reduced by 38°C and the burned edge area was reduced by 85%. More importantly, the successful increase in the yield rate to 93%, which can increase the economic benefits of about 2 million yuan to the enterprise each year. In addition, the service life of abrasive tools has also been extended by 25%, greatly reducing production costs.

The second case is an art studio focused on marble carving. Because the marble is soft, it is very easy to cause edge burning during processing, which seriously affects the artistic effect of the work. The studio head reported that in the past, making a complex relief work often required repeated repairs and burning of edges, which took a lot of time and energy. Since the use of polyurethane composite anti-heartburn agent, this problem has been effectively solved. Through comparative experiments, it was found that after using this product, the temperature fluctuation range of the marble surface was reduced by 60%, and the edge burning phenomenon was basically eliminated. More importantly, the clarity and precision of the engraving details have been significantly improved, and the overall texture of the work has been greatly improved. According to statistics, work efficiency has been improved by 40%, and customer satisfaction has also been greatly improved.

In order to display the application effect more intuitively, we have compiled the following comparison data:

Processing Parameters Traditional Method Use polyurethane composite anti-living agent
Surface temperature (°C) 180±25 142±15
Fired edge area (%) 15 <2
Free rate (%) 75 93
Abrasive tool life (hours) 40 50
Energy consumption (kWh/ton) 12 10

These practical application cases fully demonstrate the significant effect of polyurethane composite anti-heartburn agent in improving the quality of stone processing. Whether it is large-scale industrial production or refined artistic creation, this product can provide reliable solutions to help enterprises achieve cost reduction and efficiency while ensuring product quality.
