Jinwei EVA Solar Film Equipment Jiangsu Packaging Film Production Line

Description :

　　EVA solar encapsulation film production line

　　Using ethylene vinyl acetate copolymer (EVA) as the raw material, it has good adhesion, weather resistance, transparency, and excellent UV resistance. Its heat resistance, high temperature resistance, and high humidity resistance not only provide short-term adhesion to glass, solar cells, and backplates, but also have superior long-term adhesion performance.

　　EVA solar encapsulation film production line

　　Automatic weighing measuring device ensures accurate feeding of various solids, liquids, 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 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 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 is limited by the requirement of shrinkage rate, and the production speed almost depends on the extrusion speed when the melt flows out of the mold, resulting in the inability to increase the production speed.

　　Jinwei's low shrinkage EVA photovoltaic film extrusion technology has made a breakthrough in this area. Through the development of a stress device, the residual stress generated during the stretching and production process of EVA film can be effectively addressed online, thereby effectively solving the problem of thermal shrinkage of EVA film.
