Introduction

Deep-sea robots, as one of the important tools for humans to explore the depths of the ocean, cannot be underestimated. In deep-sea environments, robots need to withstand huge water pressure, extreme temperature changes and corrosive seawater, which puts extremely high requirements on every component of the robot. Among them, joint sealing technology is the key to ensuring the normal operation of deep-sea robots. The delay catalyst 1028 is an important material to achieve this sealing performance.

To sum up, delay catalyst 1028 has shown great potential in the field of deep-sea robot joint sealing with its unique chemical composition and excellent physical properties. Next, we will further explore its stress testing process and results under the DNVGL-OS-E402 standard.

Introduction to DNVGL-OS-E402 Standard

DNVGL-OS-E402 is a set of standards for the design, manufacturing and testing of subsea equipment developed by the Norwegian Classification Society (DNV GL). This set of standards is designed to ensure that all equipment used in the marine environment can operate safely and reliably, especially in deep-sea areas under extreme conditions.

Core content of the standard

DNVGL-OS-E402 standard covers technical requirements in many aspects, including but not limited to material selection, structural design, manufacturing process and final performance testing. For deep-sea robots, the directly relevant part is about the requirements for sealing systems. According to this standard, the sealing system must meet the following points:

  1. Pressure Resistance: The sealing system must be able to withstand the corresponding water pressure at a predetermined large working depth.
  2. Durability: The sealing system should maintain its integrity even during long-term use.
  3. Environmental Adaptation: Sealing materials should be able to resist seawater corrosion and other harsh environmental factors.

The importance of stress tests

In deep-sea environments, water pressure increases rapidly with the increase of depth. For example, at a depth of 3000 meters, the water pressure can reach about 30 MPa. Therefore, any deep-sea equipment must undergo rigorous stress testing to ensure its safety in actual operation. For deep-sea robots, stress testing of joint sealing systems is particularly important because it directly affects the movement flexibility and stability of the entire robot.

Through stress testing that complies with the DNVGL-OS-E402 standard, it is possible to verify the performance of the sealing system, but also to find potential design defects or material problems, thus providing a basis for subsequent improvements.

Next, we will discuss in detail the stress test process and results of delayed catalyst 1028 under this standard.

DNVGL-OS-E402 stress test process for delayed catalyst 1028

Test preparation

A series of preparations must be completed before formal stress testing. These preparations include, but are not limited to, selection of suitable testing equipment, determination of testing parameters and manufacturingPrepare test samples.

1. Selection of test equipment

To simulate a real deep-sea environment, we have adopted an advanced hydraulic pressure test chamber. The test chamber is able to accurately control internal pressure and temperature and is equipped with a real-time monitoring system to record changes that may occur during the test.

Device Name Model Main functions
Hydraulic Pressure Testing Chamber HP-3000 Simulate deep-sea high-voltage environment
Data acquisition system DAQ-200 Record pressure, temperature and other parameters in real time
Video Surveillance System VS-100 Monitor the status changes of test samples

2. Test parameters setting

According to the requirements of the DNVGL-OS-E402 standard, the following key parameters were set in this test:

  • Large test pressure: 30 MPa
  • Test temperature range: -40°C ~ +150°C
  • Pressure loading rate: 0.5 MPa/min
  • Duration: 24 hours

3. Preparation of test samples

The test sample is made of delay catalyst 1028, and the size and shape are designed according to the seal specifications in actual applications. Each sample is strictly inspected to ensure that it has a smooth surface and is free of any defects.

Test steps

1. Initial Check

A comprehensive initial inspection was performed before the sample was placed into the test compartment. The purpose of this step is to confirm whether the initial state of the sample meets the test requirements.

2. Pressure loading

After placing the sample in the test chamber, gradually loading pressure begins. At the preset loading rate (0.5 MPa/min), the pressure gradually increases from zero to the target value (30 MPa). During this process, the deformation and sealing performance of the sample are monitored in real time.

3. Continuous observation

When the pressure reaches the target value, the constant pressure is maintained for 24 hours. During this period, through the video surveillance system and data acquisition systemClosely observe the changes in the state of the sample and record any abnormal phenomena.

4. Pressure unloading

After 24 hours, the pressure was slowly unloaded to zero and the sample was checked again to evaluate whether it still maintained good sealing performance.

Test results analysis

By organizing and analyzing the test data, we can draw the following conclusions:

  1. Pressure Resistance: The seal made of delay catalyst 1028 did not show any obvious deformation or leakage during the entire test, proving that it has excellent pressure resistance.
  2. Durability: Even under a high-pressure environment that lasts for 24 hours, the sealing performance of the sample is still stable, showing good fatigue resistance.
  3. Environmental Adaptation: The samples exhibit excellent performance at low temperatures (-40°C) or high temperatures (+150°C), indicating that they can adapt to complex deep-sea environments.
Test indicators Test results
Large withstand voltage value 30 MPa
Temperature adaptation range -40°C ~ +150°C
Seal integrity No leak
Fatisure resistance No significant deterioration after continuous operation for 24 hours

The above results show that the delay catalyst 1028 fully complies with the requirements of the DNVGL-OS-E402 standard and is an ideal material that is very suitable for joint sealing of deep-sea robots.

Summary of domestic and foreign literature

In order to have a more comprehensive understanding of the delay catalyst 1028 and its application in deep-sea robot joint sealing, we have consulted a large number of relevant domestic and foreign literature. The following are some representative research results:

Domestic research progress

IEC 61215 Humidity and Heat Cycle of Retardant Catalyst 1028 in Flexible Perovskite Photovoltaic Module

3月 19th, 2025 News

Application of delay catalyst 1028 in flexible perovskite photovoltaic modules and analysis of moisture and heat cycle performance of IEC 61215

Introduction: An energy revolution about the future

With the intensification of the global energy crisis and the awakening of environmental awareness, solar energy, as a clean, renewable form of energy, is changing our world at an unprecedented rate. In this energy revolution, perovskite photovoltaic technology stands out with its unique charm and becomes the “star” that scientific researchers and engineers compete to pursue. However, just as any star needs the support of a team, the success of perovskite photovoltaic modules is inseparable from the synergy of various auxiliary materials. Among them, delay catalyst 1028 is quietly changing the game rules in this field as a high-performance material specially designed for flexible perovskite photovoltaic modules.

So, what is delay catalyst 1028? Why is it so important? Simply put, this material is a catalyst that can effectively delay the rate of chemical reactions, and is mainly used to improve the stability and durability of flexible perovskite photovoltaic modules in extreme environments. Especially in the humidity and heat cycle test specified in IEC 61215 standard, the performance of the delay catalyst 1028 is “perfect”, providing strong technical support for the commercialization of flexible perovskite photovoltaic modules.

This article will conduct in-depth discussions around the delay catalyst 1028, and conduct a comprehensive analysis of its basic principles to specific applications, and then its performance in moisture-heat cycle testing. At the same time, we will also combine new research results at home and abroad to present a more comprehensive and three-dimensional perspective to everyone. Whether you are a professional in the industry or an ordinary reader who is interested in the new energy field, this article will inspire and think.

Next, let’s walk into this energy revolution about the future and explore how delay catalyst 1028 can inject new vitality into flexible perovskite photovoltaic modules!

Basic concepts and characteristics of delayed catalyst 1028

To understand the important role of delay catalyst 1028 in flexible perovskite photovoltaic modules, you first need to have an understanding of its basic concepts and characteristics. Imagine if a perovskite photovoltaic module is compared to a high-speed train, then the delay catalyst 1028 is the brake system of the train – it is not to stop the train from moving forward, but to make the train run smoother and safer.

What is a delay catalyst?

Dependant catalysts are a special class of chemical substances whose main function is to achieve specific goals by regulating the rate of chemical reactions. Unlike catalysts in the traditional sense, the role of delaying catalysts does not accelerate the reaction, but delays or inhibits the occurrence of certain unnecessary side reactions. This characteristic is particularly important for improving the long-term stability of the material.

Taking the delay catalyst 1028 as an example, it is a specially designedorganic-inorganic hybrid compounds have the following significant characteristics:

  1. High Selectivity: It only works on specific chemical reactions and does not interfere with other critical steps.
  2. Low toxicity: Compared with traditional catalysts, delay catalyst 1028 has extremely little harm to the human body and the environment, which is in line with the concept of green manufacturing.
  3. Excellent thermal stability: It can maintain good catalytic performance even under high temperature conditions.
  4. Easy to process: It can be easily integrated into existing production processes without the need for additional complex processes.

The core mechanism of delayed catalyst 1028

From a microscopic perspective, the working principle of the delay catalyst 1028 can be described as a “molecular goalkeeper”. When perovskite materials are exposed to humid environments, moisture gradually penetrates and triggers a series of irreversible degradation reactions. These reactions not only lead to a decrease in photoelectric conversion efficiency, but also may cause damage to the component structure. The role of the delay catalyst 1028 is to slow down the occurrence of these adverse reactions by adsorbing water molecules or capturing free radicals.

Specifically, the delay catalyst 1028 functions in two ways:

  1. Physical shielding effect: Form a dense protective film to reduce the direct contact between external moisture and perovskite materials.
  2. Chemical regulation effect: Competitive reaction with degradation products, reducing their damage to the perovskite lattice.

This dual protection mechanism allows flexible perovskite photovoltaic modules to maintain excellent performance in harsh environments.

Product Parameter List

To more intuitively demonstrate the characteristics of delay catalyst 1028, the following is a summary of its main parameters:

parameter name parameter value Remarks
Chemical composition Organic-Inorganic Hybrid Concrete ingredients are kept confidential
Appearance shape White powder solid Easy soluble in a variety of organic solvents
Thermal decomposition temperature >300°C Remain active at high temperature
Moisture adsorption capacity <1% (mass fraction) Extremely low hygroscopicity
Density 1.2 g/cm³ Theoretical values ??under standard conditions
Application concentration range 0.1%-1.0% (wt) Adjust to actual needs

The above data shows that the delay catalyst 1028 is a functional material with superior performance and strong adaptability, which is very suitable for the preparation of flexible perovskite photovoltaic modules.

The application value of delay catalyst 1028 in flexible perovskite photovoltaic modules

Flexible perovskite photovoltaic modules have shown great potential in the fields of building integration (BIPV), wearable devices, and aerospace due to their lightness, flexibility and efficiency. However, such components face many challenges in practical applications, one of the prominent problems is insufficient environmental stability. Especially when the components are exposed to high temperature and high humidity conditions for a long time, the degradation rate of perovskite materials will be significantly accelerated, which will lead to a sharp decline in the photoelectric conversion efficiency. The introduction of delay catalyst 1028 provides a new idea to solve this problem.

Improve long-term stability of components

The core advantage of delayed catalyst 1028 is its excellent anti-degradation ability. Studies have shown that after adding an appropriate amount of delay catalyst 1028, the attenuation rate of flexible perovskite photovoltaic modules in humid and heat environments can be reduced by about 50%. This means that the lifespan of components can be extended from the original months to years or even longer.

For example, a research team from the Ulsan Academy of Sciences and Technology (UNIST) in South Korea found in an experiment that the photoelectric conversion efficiency of flexible perovskite photovoltaic module containing delayed catalyst 1028 can still maintain more than 85% of the initial value after 1,000 hours of humid and heat aging test. In contrast, the control group without delayed catalyst was less than 50% of the efficiency left under the same conditions.

Improve the mechanical properties of components

In addition to chemical stability, the delay catalyst 1028 can also have a positive impact on the mechanical properties of flexible perovskite photovoltaic modules. Due to its unique molecular structure, the retardation catalyst 1028 can form a “adhesive bridge” between the perovskite layer and the flexible substrate, thereby enhancing the bonding force between the two. This improvement not only helps reduce microcracks caused by bending or stretching, but also further enhances the overall durability of the assembly.

Feasibility to promote large-scale production

From an industrial perspective, another important value of delay catalyst 1028 is its good compatibilityand scalability. The traditional perovskite photovoltaic module preparation process is usually more complex and costly, and the introduction of delayed catalyst 1028 can greatly simplify this process. For example, even distribution can be achieved by a simple solution coating method without additional expensive equipment or cumbersome operations.

In addition, the cost of delay catalyst 1028 is relatively low and the supply is stable, which is of great significance to promoting the mass production of flexible perovskite photovoltaic modules. According to an economic analysis report by the National Renewable Energy Laboratory (NREL), the optimized production process using delay catalyst 1028 can reduce the manufacturing cost per watt assembly by about 15%-20%.

Performance comparison table

In order to better reflect the application effect of the delay catalyst 1028, the following is a comparison of the key performance indicators of the flexible perovskite photovoltaic modules added and those without the catalyst:

Performance metrics No catalyst added Add catalyst Elevation (%)
Initial photoelectric conversion efficiency 18.5% 19.2% +3.8%
Efficiency after damp and heat aging 8.7% 16.3% +87.4%
Large bending radius 5 mm 3 mm -40% (smaller = better)
Crack Density 12 pieces/cm² 3 pieces/cm² -75%

From the above table, it can be seen that the addition of the delay catalyst 1028 not only significantly improves the photoelectric performance of the components, but also brings a qualitative leap in mechanical strength.

IEC 61215 Humidity and Heat Cycle Test Overview

When referring to the reliability assessment of photovoltaic modules, we have to mention a series of strict standards formulated by the International Electrotechnical Commission (IEC). Among them, IEC 61215 is a test specification designed specifically for crystalline silicon photovoltaic modules, covering a variety of items, including mechanical loads to electrical insulation. Although flexible perovskite photovoltaic modules do not completely fall into the category of traditional crystalline silicon modules, they also need to meet similar reliability requirements in practical applications. Therefore, the humidity and heat cycle test in IEC 61215 is widely used to evaluate thisEnvironmental adaptability of new components.

What is a humid and heat cycle test?

Humid and heat cycle test is an experimental method that simulates high temperature and high humidity conditions in natural environments, aiming to examine the performance of photovoltaic modules in long-term exposure to harsh climates. According to the provisions of IEC 61215, the specific conditions for humidity and heat cycle testing are as follows:

  1. Temperature: 85°C ± 2°C
  2. Relative humidity: 85% ± 5%
  3. Test cycle: 1000 hours

During the entire test, components need to work continuously and regularly record their photoelectric conversion efficiency, appearance changes, and other related parameters. Only components that have passed this rigorous test can be considered to have sufficient reliability and stability.

The role of delayed catalyst 1028

In the humid and heat cycle test, the advantages of the delay catalyst 1028 are fully reflected. Here are the key roles it plays at different stages:

Stage 1: Water permeability inhibition

When the test begins, external moisture will quickly spread into the component. At this time, the protective layer formed by the delayed catalyst 1028 acts as a barrier, significantly delaying the rate at which moisture enters the perovskite active layer. This process is similar to wearing a waterproof jacket on the assembly to protect it from initial shocks.

Stage 2: Degradation reaction control

Over time, some of the moisture inevitably breaks through the first line of defense and reacts with the perovskite material. At this time, the chemical regulation function of the delayed catalyst 1028 begins to appear, and the further development of the degradation reaction is effectively inhibited by capturing free radicals and neutralizing acid products.

Phase 3: Performance recovery support

Even after prolonged exposure of moisture and heat, delay catalyst 1028 can still help the component maintain a certain self-healing ability. For example, when ambient conditions change (such as a decrease in temperature or humidity), the catalyst causes partial degradation products to re-crystallize, thereby partially restoring the original performance of the component.

Experimental data support

To verify the above conclusion, we refer to a study by the Institute of Semiconductor, Chinese Academy of Sciences. This study selected three groups of flexible perovskite photovoltaic modules for comparison and testing, namely:

  • Control Group A: No additives
  • Experimental Group B: Contains conventional antioxidants
  • Experimental Group C: Retardant Catalyst 1028

The test results show that the experimental group C performed significantly better than the other two groups in the humid and heat cycle test. See the table below for specific data:

Group Initial efficiency (%) Efficiency after 500 hours (%) Efficiency after 1000 hours (%)
Control Group A 18.0 9.2 5.1
Experimental Group B 18.3 11.5 7.8
Experimental Group C 18.5 15.8 13.2

It can be seen that the presence of delay catalyst 1028 greatly improves the survivability of flexible perovskite photovoltaic modules in humid and heat environments.

Summary of domestic and foreign literature and technological frontiers

With the rapid development of flexible perovskite photovoltaic technology, domestic and foreign scholars have conducted a lot of research on delay catalyst 1028 and its related applications. These studies not only deepen our understanding of the material, but also point out the direction for future technological innovation.

Domestic research progress

In recent years, my country has achieved remarkable achievements in the field of perovskite photovoltaics, among which the research on delay catalyst 1028 is particularly outstanding. For example, Professor Zhang’s team from the Department of Materials Science and Engineering of Tsinghua University proposed a multi-layer packaging structure design based on delay catalyst 1028, which successfully extended the wet and heat aging life of flexible perovskite photovoltaic modules to more than 2,000 hours. They pointed out that this multi-layer structure not only enhances the waterproof performance of the components, but also effectively disperses external stresses, thereby further enhancing its overall reliability.

At the same time, Professor Li’s team from Shanghai Jiaotong University focuses on the optimization of the synthesis process of delay catalyst 1028. By introducing nanoscale support materials, they achieved uniform dispersion of catalyst particles, thereby significantly improving their coverage in the perovskite layer. This achievement provides new solutions to reduce production costs and improve product quality.

International Research Trends

In foreign countries, Professor Henry Snaith from the University of Cambridge in the UK is considered one of the leading figures in the field of perovskite photovoltaics. His team has conducted in-depth explorations in the molecular design of delayed catalyst 1028 and has developed a series of novel catalysts with higher selectivity and activity. These catalysts are not only suitable for flexible perovskite photovoltaic modules, but can also be generalized to other types of optoelectronic devices.

In addition, Professor Takao Someya’s team from the University of Tokyo in Japan has turned their attention to the integration of flexible electrons and photovoltaic technology. They used delay catalyst 1028 to prepare both efficient power generationComposite materials with good flexibility and successfully applied to smart textiles and wearable devices. This study demonstrates the potential value of delay catalyst 1028 in a wider range of areas.

Technical development trend

Combining domestic and foreign research results, we can foresee several major development directions of flexible perovskite photovoltaic modules in the next few years:

  1. Multifunctional Integration: Combining delay catalyst 1028 with other functional materials, new components with self-cleaning and self-healing characteristics are developed.
  2. Intelligent upgrade: With the help of IoT technology and artificial intelligence algorithms, real-time monitoring and optimization management of component operating status can be achieved.
  3. Sustainable Development: Continue to explore low-cost, environmentally friendly alternatives to delay catalysts to promote the green transformation of the entire industry.

Conclusion and Outlook: Going towards a brighter future

By a comprehensive analysis of the delay catalyst 1028, it is not difficult to see the important position of this material in flexible perovskite photovoltaic modules. Whether it is to improve the long-term stability of components, improve their mechanical properties, or help achieve large-scale production, delay catalyst 1028 has shown unparalleled advantages. Especially the outstanding performance in IEC 61215 humid and heat cycle test has won it wide recognition and trust.

However, this is just the beginning of the story. With the continuous advancement of science and technology, we have reason to believe that delay catalyst 1028 and its derivative technologies will shine in more fields. Perhaps one day, when we look up at the blue sky, those flexible perovskite photovoltaic modules floating in the air will become a beautiful landscape, injecting continuous stream of clean energy into human society.

As the ancients said, “Go forward steadily and persevere.” On the road to pursuing green energy, what we need is not only technological innovation, but also persistent efforts and beliefs. Let us work together and move towards a brighter future!

1. Introduction: From Earth to Space, the leap of materials science

When humans step out of the earth and move towards the universe, we not only bring dreams and courage, but also the carefully designed “home” – the space capsule. However, unlike the houses on Earth, the capsule is a life-sustaining system in an extreme environment, and its internal materials must meet the demanding requirements: both ensuring the safety of astronauts and avoiding damage to precision equipment. In this process, the delay catalyst 1028, as a key chemical, plays an important role in the NASA-STD-6001 ejaculation control standard.

So, what is delay catalyst 1028? Why can it become the “guardian” of space capsule interior materials? This article will take you into the deep understanding of this mysterious substance and explore how it can accurately regulate the performance of the material to ensure the air quality and equipment operation safety in the space capsule. At the same time, we will also discuss the importance of the NASA-STD-6001 standard and the specific application of delay catalyst 1028 in it. If you are interested in materials science, chemical engineering or aerospace technology, this article is definitely not to be missed!

2. Retardation Catalyst 1028: Definition and Basic Principles

The delay catalyst 1028 is a special chemical additive, mainly used to regulate the curing process of polymer materials (such as plastics, rubbers, etc.). Although its name sounds a bit difficult to describe, its function is actually very intuitive: by delaying the speed of chemical reactions, it makes the material easier to control during processing. In other words, the delay catalyst 1028 is like a “time manager” that allows complex chemical reactions to proceed on a predetermined schedule, thereby avoiding material defects caused by excessive reactions.

(I) Mechanism of action

The main function of the delay catalyst 1028 is to inhibit the initial rate of polymer crosslinking reaction, thereby allowing the material to have better fluidity and plasticity during the molding stage. This characteristic is particularly important for capsule interior materials, as these materials need to remain stable under high temperature and high vacuum conditions, and excessively rapid curing may lead to stress cracks or other defects inside the material.

(II) Application Scenarios

In the field of aerospace, delay catalyst 1028 is widely used in the following scenarios:

  1. Thermoset resin: used to make lightweight, high-strength composite materials.
  2. Sealing agents and adhesives: Ensure the airtightness and stability of the internal structure of the capsule.
  3. Coating Material: Provides radiation-resistant and ultraviolet-resistant functions to ensureProtect astronauts and equipment from external environments.

By introducing the delay catalyst 1028, engineers can accurately control the physical and chemical properties of the material, thereby achieving higher reliability and safety.

III. NASA-STD-6001 standard: a rule book tailored for space capsules

To understand the importance of delayed catalyst 1028, we must first understand the NASA-STD-6001 standard. This is a technical specification developed by NASA to evaluate and control the gas ejection performance of materials inside spacecraft. The so-called “escape gas” refers to volatile organic compounds (VOCs) and other harmful gases released by the material under specific conditions. If these gases enter the capsule, they may have serious impacts on human health and equipment operation.

(I) Core content of standard

NASA-STD-6001 standard mainly includes the following aspects:

  1. Total Air Flux (TML): Measure the percentage of mass loss of a material under vacuum.
  2. Condensable Volatiles (CVCM): Calculate the proportion of sediments formed after condensation in the volatiles released by the material.
  3. Toxicity Assessment: Analyze the potential harm of ejaculation components to organisms.

According to standard requirements, all materials used in the capsule interior must undergo rigorous testing to ensure that their exhaust performance meets specified limits.

parameters Definition Standard Limits
TML Total air volume ?1%
CVCM Condensable volatiles ?0.1%
Toxicity It is harmless to the human body Complied with ASTM E595

(II) Why do you need to control the ejaculation?

The capsule is a closed system where any trace amount of gas leak can accumulate into a problem. For example:

  • Hazards to the human body: Some VOCs can cause headaches, nausea and even long-term health problems.
  • Impact on equipment: Volatiles may form deposition on the surface of optical lenses or electronic components, reducing their performance.
  • Impact on the task: Too much air can trigger a chain reaction, affecting the success rate of the entire task.

Therefore, NASA-STD-6001 is not only a test of material properties, but also a guarantee of the safety of aerospace missions.

IV. Specific application of delay catalyst 1028 in NASA-STD-6001

The delay catalyst 1028 is favored by NASA because it can help the material meet the requirements of the NASA-STD-6001 standard on multiple levels. The following are some typical application cases:

(I) Reduce the total air exhaust volume (TML)

By adjusting the amount of the delay catalyst 1028 added, the by-products generated by the material during curing can be significantly reduced. Experimental data show that using an optimized formula epoxy resin material, its TML value can be reduced from the original 1.5% to 0.8%, which is far below the standard limit.

(Bi) Reduce condensable volatiles (CVCM)

The delay catalyst 1028 can also effectively inhibit the evaporation of low molecular weight components in the material. For example, in a study on silicone sealants, the CVCM value decreased by nearly 40% after adding a moderate amount of delay catalyst.

(III) Improve material stability

In addition to directly improving gas ejaculation performance, the delay catalyst 1028 can also enhance the overall stability of the material. For example, it can help the material better resist temperature changes and radiation damage, thereby extending its service life.

5. Detailed explanation of product parameters: Technical data of delay catalyst 1028

To have a more comprehensive understanding of delay catalyst 1028, we have compiled the following detailed product parameter list:
