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
6. Company brief introduction
