First of all, we need to understand the basic working principle of solar panels. Solar panels, as the name suggests, are devices that convert sunlight into electrical energy. Its core component is photovoltaic cell, which is what we often call solar cell.

The working principle of photovoltaic cells is actually very simple: when sunlight shines on the surface of the cell, photons will stimulate electrons inside the cell and generate current. After this current is processed by a series of circuits, it can provide us with power.

1.2 Components of solar panels

A complete solar panel is usually composed of the following parts:

Photovoltaic cell: Responsible for converting light energy into electrical energy.
Glass Panel: Protects photovoltaic cells while allowing light to pass through.
Backboard: Protect the back of the battery to prevent moisture and dust from entering.
Border: Supports the entire panel and provides structural stability.
junction box: Connect the battery panel to the external circuit.

What we are going to focus on today is the part of Border. You may think that the bezel is a “supporting role”, but in fact, it plays a very important role in the performance and life of the entire panel.

2. The importance of borders

2.1 The role of border

The main function of the border is to support and protect solar panels. It not only has to withstand the weight of the battery panel, but also has to withstand the erosion of natural environments such as wind, rain, and snow. In addition, the frame also plays a role in heat dissipation, helping the panel maintain stable operation in high temperature environments.

2.2 Limitations of traditional border materials

The frames of traditional solar panels are usually made of aluminum alloy. Aluminum alloys are light and corrosion-resistant, but have limitations in some aspects:

Weight: Although aluminum alloy is relatively light, the weight of the frame is still a problem that cannot be ignored for large solar power plants.
Thermal conductivity: Aluminum alloy has good thermal conductivity, but in extreme high temperature environments, it may cause overheating of the battery panel and affecting efficiency.
Cost: The price of aluminum alloys is relatively high, especially when raw material prices fluctuate, cost control becomes difficult.

III. Introduction of polyurethane tensioning agent

3.1 What is polyurethane tension agent?

Polyurethane tensile agent is a new type of polymer material with excellent properties such as high strength, light weight, corrosion resistance, and high temperature resistance. It was first widely used in automobiles, construction and other fields, and has been gradually introduced into the manufacturing of solar panels in recent years.

3.2 Advantages of polyurethane tensioning agent

Compared with traditional aluminum alloys, polyurethane tension agents have obvious advantages in the following aspects:

Lightweight: Polyurethane has a lower density than aluminum alloys, so using polyurethane tension agents can significantly reduce the weight of the frame.
Corrosion resistance: Polyurethane materials have good resistance to corrosive substances such as acids, alkalis, and salts, and are suitable for use in harsh environments.
High temperature resistance: Polyurethane has excellent high temperature resistance and can remain stable in extreme high temperature environments, which helps improve the working efficiency of the battery panel.
Low cost: The production cost of polyurethane is relatively low, especially during large-scale production, which can effectively reduce the overall cost.

IV. Application of polyurethane tension agent in the frame of solar panels

4.1 Mechanism to improve energy conversion efficiency

You may have questions: How can a small frame material affect the energy conversion efficiency of the entire solar panel? In fact, there are several key points here:

Selecting and Application of Polyurethane Sponge Hardening Agent

4.1 Select the right hardener

Selecting a suitable hardener requires consideration of multiple factors, including the product’s use environment, performance requirements, cost, etc. For example, refrigerator door sealing strips require higher hardness and temperature resistance, so organic hardeners can be selected; while washing machine shock absorbing pads require better elasticity, inorganic hardeners can be selected.

4.2 Addition of hardener

The amount of hardener added has an important impact on the performance of the product. If the amount of addition is too small, the hardening effect will not be obvious; if the amount of addition is too large, the material may become brittle. Generally, the added amount of hardener is 5%-20% of the total amount of polyurethane sponge.

Application Scenario Doing amount of hardener (%)

Refrigerator door seal 10-15

Washing machine shock absorber pad 5-10

Air conditioning filter 15-20

Vacuum cleaner filters sponge 10-15

4.3 Mixing and processing of hardener

Hardening agents are usually added to polyurethane sponges in powder or liquid form. When mixing, it is necessary to ensure that the hardener is evenly distributed to avoid locally being too hard or too soft. During the processing process, temperature and time are also important factors affecting the hardening effect.

Processing Parameters Recommended Value

Mixing temperature (℃) 20-30

Mixing time (min) 10-20

Molding temperature (℃) 100-120

Forming time (min) 5-10

The impact of polyurethane sponge hardener on user experience

5.1 Improve the durability of the product

Hardening agents can increase the hardness and strength of polyurethane sponges, thereby extending the service life of the product. For example, after using hardener, the sealing effect of refrigerator door sealing strips is better, and the refrigerator has a higher refrigeration efficiency, so users do not need to change the sealing strips frequently.

5.2 Improve product comfort

The hardener can make the polyurethane sponge have good elasticity while maintaining a certain hardness. For example, after using hardener, the sofa seat cushion will not be too soft to cause discomfort in sitting feeling, nor will it be too hard to affect comfort.

5.3 Reduce product maintenance costs

Hardening agents can improve the wear resistance and temperature resistance of polyurethane sponges and reduce product maintenance costs. For example, after using hardener, the shock absorption pad of the washing machine has better shock absorption effect and lower noise, so users do not need to change the shock absorption pad frequently.

5.4 Improve the energy-saving effect of the product

Hardening agents can improve the sealing and thermal insulation of polyurethane sponges, thereby improving the energy-saving effect of the product. For example, after using hardener, the sealing effect of refrigerator door sealing strips is better, the air conditioning is not easy to leak, and the refrigerator’s energy consumption is lower.

Future development trends of polyurethane sponge hardener

6.1 Environmentally friendly hardener

With the increase in environmental awareness, environmentally friendly hardener will become the future development trend. Environmentally friendly hardener not only has good hardening effects, but is also environmentally friendly and meets the requirements of sustainable development.

6.2 High-performance hardener

With the continuous upgrading of home appliances, the performance requirements for hardeners are getting higher and higher. In the future, high-performance hardeners will become the mainstream, with higher hardness, better temperature resistance and longer service life.

6.3 Intelligent hardener

With the popularity of smart home appliances, intelligent hardener will also become the future development trend. Intelligent hardener can automatically adjust the hardness according to conditions such as ambient temperature and humidity to improve the intelligent level of the product.
