Application of foaming delay agent 1027 in the insulation layer of smart agricultural greenhouses and optimization of aging coefficient of EN 14307

Introduction: A “revolution” about insulation

In this era of interconnected things, smart agriculture is changing our lives at an unprecedented speed. From precise irrigation to intelligent temperature control, the tentacles of technology have penetrated into every detail. Among these high-tech equipment, there is a seemingly inconspicuous but crucial technology – the insulation layer. Like a thoughtful down jacket, it provides a warm and comfortable growing environment for crops.

However, traditional insulation materials often have a fatal problem: their performance gradually declines over time. This is like if a piece of clothing is worn for a long time, the warmth effect will naturally be reduced. To address this challenge, scientists have turned their attention to a magical chemical, foam delaying agent 1027. This substance can not only significantly improve the performance of the insulation material, but also effectively delay its aging process and keep the insulation layer in good condition at all times.

This article will discuss the application of foaming retardant 1027 in the insulation layer of smart agricultural greenhouses, focusing on analyzing its optimization effect on the aging coefficient of EN 14307. By in-depth research on relevant domestic and foreign literature, combined with actual cases and experimental data, we will reveal how this technology injects new vitality into modern agriculture. At the same time, we will also lead readers to understand the mysteries of this field in an easy-to-understand language and vivid and interesting metaphors.

So, let’s start this “revolutionary” journey about the insulation layer!

Introduction to Foaming Delay Agent 1027: “Time Traveler” in the Chemistry World

Foaming delay agent 1027 is a powerful chemical that is often used in the production of polyurethane foam. Its main function is to adjust the foaming rate, thereby ensuring that the foam structure is more uniform and stable. If the formation of polyurethane foam is compared to a carefully arranged symphony, then foaming delay agent 1027 is the indispensable conductor, which precisely controls the rhythm and intensity of each note, allowing the entire performance to achieve perfect harmony.

Chemical properties and mechanism of action

Foaming retardant 1027 is an organic compound whose molecular structure contains specific functional groups and can weakly interact with isocyanates in the polyurethane reaction system. This weak interaction causes the activity of isocyanate to be inhibited to a certain extent, thereby delaying the rate of foam generation. Specifically, the mechanism of action of foaming retardant 1027 includes the following aspects:

Reduce the reaction rate: By temporarily binding with isocyanate, it reduces its immediate reaction with polyols, thereby delaying the rapid expansion of the foam.
Improve foam stability: Because the foaming process is slower and controllable, the wall thickness of the foam bubbles is evenly distributed, reducing the possibility of bubble bursting.
Enhanced Mechanical Properties: By optimizing the foam structure, the final polyurethane material has higher strength and better thermal insulation properties.

Status of domestic and foreign research

In recent years, with the increase of environmental awareness and the growth of energy-saving demand, the application scope of foaming delay agent 1027 has been continuously expanded. Foreign studies have shown that this substance has performed well in the fields of building insulation, refrigeration transportation, and especially plays an important role in improving the durability and thermal stability of foam materials (Smith et al., 2018). Domestic scholars have further explored their potential in the agricultural field and found that it has significant effects on optimizing the aging coefficient of greenhouse insulation layer (Li Hua et al., 2020).

In short, foaming retardant 1027 has become one of the indispensable and important raw materials in modern industry with its unique chemical characteristics and wide application prospects.

EN 14307 Overview of Aging Coefficient: “Life Code” of Insulation Materials

EN 14307 is a European standard designed to evaluate the long-term performance and aging behavior of thermal insulation materials. Simply put, it is like a “physical examination report” for insulation materials. Through a series of rigorous tests, it determines the durability of the material under different environmental conditions. For wisdomFor agricultural greenhouses, it is crucial to choose insulation materials that meet EN 14307 standards, because this is directly related to the service life and energy efficiency of the greenhouse.

Definition and importance of aging coefficient

The aging coefficient refers to the degree to which the performance of the insulation material decreases due to physical or chemical changes during use. To put it in a figurative metaphor, it is like the butter on a piece of cake that will gradually melt and disappear over time. If the aging coefficient is too high, it means that the insulation performance of the insulation layer will rapidly attenuate, resulting in an intensified temperature fluctuation in the greenhouse and affect crop growth.

According to EN 14307, the aging coefficient is usually measured in the following ways:

Thermal Aging Test: Simulate high-temperature environments and observe material dimensional changes and thermal conductivity.
Humidity and Heat Cycle Test: Evaluate the stability of the material under high humidity and repeated alternating heat and heat.
Ultraviolet aging test: Test the anti-degradation ability of a material under direct sunlight.

Critical Challenges

Although EN 14307 provides a unified evaluation standard for insulation materials, there are still many problems in practical applications. For example, when many traditional insulation materials face complex and changeable agricultural environments, the aging coefficient is relatively high, making it difficult to meet the needs of long-term use. In addition, although some low-cost materials have good initial performance, their thermal insulation will drop significantly over time, increasing energy consumption and maintenance costs.

Therefore, how to reduce the aging coefficient of insulation materials through technological innovation has become a key issue that needs to be solved urgently.

The influence of foaming retardant 1027 on the aging coefficient of EN 14307: A scientific contest

Experimental Design and Method

To verify the specific effect of foaming retardant 1027 on the aging coefficient of insulation materials, the researchers designed a series of comparative experiments. The experiment was divided into two groups: one group used ordinary polyurethane foam as a control, and the other group added an appropriate amount of foaming retardant 1027. All samples were tested in accordance with EN 14307 standards, including three links: thermal aging, humid and heat cycle and ultraviolet aging.

Comparison of test results

Test items	Control group (normal foam)	Experimental group (including foaming delay agent 1027)
Thermal conductivity after thermal aging	0.032 W/m·K	0.028 W/m·K
Dimensional Change Rate	+3.5%	+1.8%
Strength loss after humid and heat cycle	15%	8%
Color changes after UV aging	Obvious yellowing	Slight yellowing

It can be seen from the table that the experimental group with the addition of foaming retardant 1027 showed obvious advantages in all indicators. In particular, the improvement of thermal conductivity and dimensional change rate is particularly significant, indicating that it has a positive effect on the long-term performance of thermal insulation materials.

Analysis of action mechanism

The reason why foaming retardant 1027 can effectively reduce the aging coefficient is mainly attributed to the following aspects:

Enhance the stability of foam structure: By delaying the foaming process, the foam bubble walls are more uniform and dense, reducing the possibility of moisture penetration and gas diffusion.
Improve the heat resistance of the material: The special functional groups in the foaming retardant 1027 can form stable chemical bonds with the polyurethane matrix, thereby enhancing the material’s resistance to deformation under high temperature conditions.
Inhibiting UV degradation: Experiments show that the foaming retardant 1027 can shield the destructive effect of UV rays on the material surface to a certain extent and extend its service life.

Comparison of domestic and foreign research results

A foreign research team conducted a three-year field trial on similar issues. The results showed that the aging coefficient of insulation materials containing foaming retardant 1027 in actual use is about 25% lower than that of ordinary materials (Johnson & Lee, 2019). A domestic laboratory study further confirmed that the addition of foaming retardant 1027 can extend the service life of the insulation material by at least two years (Wang Qiang et al., 2021).

Specific application of foaming delay agent 1027 in smart agriculture: from theory to practice

Smart agricultural greenhouses are a highly integrated ecosystem in which insulation plays a crucial role. By introducing the optimized insulation material of foaming delay agent 1027, it can not only improve the overall performance of the greenhouse, but also bring a series of economic and social benefits.

Winter insulation: In cold seasons, the optimized insulation layer can more effectively resistIt stops heat loss, keeps the temperature in the shed stable, reduces the operating time of the heating equipment, and saves energy costs.
Summer Cooling: In hot weather, high-performance insulation materials can reflect some solar radiation, reduce the temperature in the shed, and reduce the burden on the air conditioning system.
Extreme climate protection: In areas that are often hit by storms or frost, the enhanced material toughness of the foam delaying agent 1027 can better resist external impacts and extend the service life of the greenhouse.

Economic Benefit Assessment

According to calculations, using insulation materials containing foaming delay agent 1027 can save about 10 yuan of electricity per square meter of greenhouse per year. If the area of a standard greenhouse is 500 square meters, you can save 5,000 yuan in a year. Considering the extended service life of the material itself, the economic benefits are more significant in the long run.

Social Benefit Outlook

In addition to economic benefits, the application of foam delaying agent 1027 also brings many social benefits. For example, it helps reduce energy consumption, reduce carbon emissions, and drives agriculture towards sustainable development. At the same time, the popularity of high-quality insulation layers also provides farmers with more reliable production guarantees and improves the quality and output of agricultural products.

Conclusion and Outlook: Unlimited Possibilities in the Future

Through the above analysis, it can be seen that the application of foaming retardant 1027 in the insulation layer of smart agricultural greenhouses has broad prospects. It can not only significantly optimize the aging coefficient of EN 14307 and improve the long-term performance of materials, but also bring tangible economic benefits and social value to agricultural production.

However, there is still a lot of room to explore in this area. For example, how to further reduce costs and develop processes that are more suitable for large-scale production; how to combine new nanomaterials to achieve higher performance insulation layers, etc. I believe that with the continuous advancement of science and technology, foaming delay agent 1027 will show more amazing possibilities in the future.

As an old proverb says: “If you want to do a good job, you must first sharpen your tools.” For smart agriculture, high-quality insulation material is the sharp tool, and foaming delay agent 1027 is a whetstone, making all this better.
