What is the density of epoxy board

2023-11-29

The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or ring structure of the molecular chain. They can cross-link with various types of curing agents to form insoluble, non-fusible polymers with three-dimensional network structure, with specification thickness of 0.5 to 100 mm, and are subject to thermal deformation at high temperature of 180 ℃. Generally, they are not heated together with other metals, which may cause metal sheet deformation.

Solar photovoltaic backplane and materials used

2023-11-29

Solar cell backplane is also called solar cell backplane film, photovoltaic backplane, photovoltaic backplane film, and solar backplane. It is widely used in solar cell (PV) modules, located at the back of the solar panel, to protect the solar cell modules from moisture erosion in outdoor environment, and to prevent oxygen from internal oxidation of the modules. It has reliable insulation, water resistance, aging resistance, high and low temperature resistance, and corrosion resistance. It can reflect sunlight and improve the conversion efficiency of components; It has high infrared reflectivity, which can reduce the temperature of the module.

What are the heating membranes of new energy power batteries?

2023-11-29

First of all, the working principle of the heating film of the new energy vehicle battery is that the low temperature causes the increase of the internal resistance of the battery. By installing a device that can generate oscillating current at both ends of the battery, the current can pass through the cell with large internal resistance, so that a large amount of heat can be generated inside the battery. At last, the temperature of the battery will rise rapidly. The heating film commonly used for the new energy battery includes: silica gel heating film, PI heating film, and epoxy plate heating film. According to the application requirements, these three types are relatively common, the difference is:; The temperature resistance of silica gel heating film can reach 250 ℃, the product thickness is 1.6 ± 0.2mm, and the pressure resistance is 2500V/1Min; The temperature resistance of PI heating film is 180 degrees, the product thickness is 0.3-0.5mm, and the pressure resistance is AC1500V/1Min; The epoxy plate heating film has a temperature resistance of 180 degrees, a thickness of 0.8-2mm, and a pressure resistance of 2500V/1Min. The actual application can be customized according to the specific use.
