EVA Solar Cell Encapsulation Film Line Poe Cell Film Production Machine

1. Specification of single-extruder production line:

2. Specification of co-extrusion production line:

3. Features of EVA solar film line

(1) High transparency and high adhesion can be applied to various interfaces and used for bonding glass and silicon wafers.

(2) Good durability can resist high temperature, moisture, ultraviolet rays and so on.

(3) Easy to store. Stored at room temperature, the adhesion of EVA is not affected by humidity and water-absorbent film.

4. Characteristics of POE polyolefin film machine

(1) POE has the general characteristics of thermoplastic elastomers. The soft chain curling structure of octene and the crystalline vinyl chain are used as physical crosslinking points, making it both excellent toughness and good processability;

(2) The price is low and the relative density is small, so the volume and price are low;

(3) Excellent heat resistance and cold resistance, and a wide using temperature range;

(4) Weather resistance, good aging resistance, because there are no unsaturated double bonds in the molecular structure of POE plastics, it has excellent aging resistance;

(5) Oil resistance, compression permanent deformation and abrasion resistance are not good;

(6) POE plastics have narrow molecular amount distribution, good fluidity, and good compatibility with polyolefins;

(7) Good fluidity can improve the dispersing effect of the filler and at the same time increase the weld line strength of the product.

5. Performance characteristics of Gwell EVA/POE film production machine

(1) The cast extruder adopts EVA special single screw extrusion and POE special single screw extrusion. The screw barrel constant temperature circulating water cooling system solves the technical difficulties of EVA/POE plasticization and non-crosslinking.

(2) The roller body adopts double-sided embossing, and solves the technical difficulties of the film sticking to the roller.

(3) The cooling part adopts cooling rollers and stress-relieving cooling beds to make the film run smoothly and fully shaped to ensure that the shrinkage rate is less than 3%.

(4) The whole line adopts PLC automatic control to realize the operation of man-machine interface.

(5) The production line is equipped with an online quality monitoring and control system to ensure the product qualification rate.

(6) Patented design micro-tension winder, the line speed of the whole machine production line can reach 18m/min
