Description :
EVA solar encapsulation film production line
Made from ethylene vinyl acetate copolymer (EVA) as raw material, combined with crosslinking agent, bonding promoter, and stabilizer. It has strong adhesion, good weather resistance, transparency, and UV resistance. Its heat resistance, high temperature resistance, and high humidity resistance not only provide short-term adhesion to glass, solar cells, and backboards, but also have superior long-term adhesion performance.
EVA solar encapsulation film production line
The fully automatic weighing measuring device ensures high-precision feeding of various solid and liquid additives and raw materials.
Low temperature extrusion system prevents premature curing and cross-linking of solid agents while ensuring sufficient mixing and plasticization
The special design of the extended part perfectly solves the problems of sticking rollers and glass.
Unique online tempering stress relief device
Multiple tension control systems in the production line ensure smooth transportation of elastic sheets during cooling, traction, and winding processes.
EVA/POE photovoltaic adhesive film generally requires a thermal shrinkage rate of less than 5% to meet the requirements for battery packaging. The traditional EVA photovoltaic film extrusion production equipment, due to the requirement of shrinkage rate, almost entirely depends on the extrusion speed when the melt flows out of the mold, resulting in the inability to increase the production speed.
The newly launched low shrinkage EVA photovoltaic film high-speed extrusion technology has made significant breakthroughs in this area. Through the development of a stress relief device, residual stresses generated during the stretching and production process of EVA film can be effectively eliminated online, thereby effectively solving the problem of thermal shrinkage of EVA film.
