SPC floor Production Process-kalshine1
Process: 1 mixture
According to the ratio of raw materials for automatic weighing, high-speed mixer hot mix (thermal mixing temperature: 125 ℃, role
Is the mixing of various materials, eliminate the moisture in the material) – > enter cold mix (material cool down To prevent caking and discoloration, cold mix temperature: 55 ℃).- by cooling mixing of materials;
Process 2: extrusion
Join the twin screw extruder, heated extrusion – into the sheet forming, extrusion molding pieces
After four roll calender, base material to decide to stick color film, thick stick wear-resisting layer – cooling – cutting;
Process 3: UV tempering
Surface UV – tempered, tempering hot water temperature: 80 ~ 120 ℃;The cold water temperature: 10 ℃)
Process 4: splitting, slotting + packaging
Cutting, notching, trimming, chamfering to inspection, packaging
