introduction
eva film extrusion line raw material: EVA hot melt adhesive, chemical name: ethylene-acetic acid YI ene copolymer, EVA is a thermosetting adhesive film that is used in the middle of laminated glass. The product is extruded by heating and casting after adding imported plastic additives. The adhesive film is non-viscous at room temperature, which is convenient for cutting operation. After hot pressing, thermal cross-linking curing and bonding enhancement reaction occurs, resulting in permanent adhesive sealing. It is a novel thermosetting hot-melt adhesive film.
Performance characteristics of eva film extrusion line
- China Jwell eva film extrusion line adopts single screw extrusion for EVA and single screw extrusion for POE. The screw and barrel constant temperature circulating water cooling system solves the technical problems of EVA/POE plasticization and non-crosslinking.
- The roller body adopts double-sided embossing, which solves the technical difficulty of film sticking to the roller.
- The cooling part adopts cooling roller and stress-relieving cooling bed, so that the film runs smoothly, the molding is sufficient, and the shrinkage rate is guaranteed to be less than 3%.
- The whole line of eva film extrusion line adopts PLC automatic control to realize man-machine interface operation.
- As an eva film extrusion line manufacturer, Jwell is equipped with an online quality monitoring system to ensure product qualification rate.
- Patented design micro tension winder, the line speed of the whole machine can reach 18m/min.
