Process 1, mixing

Automatic measurement verification according to the proportion of raw materials → Hot mixing by high-speed mixer (Hot mixing temperature: 125 ° C, the effect is to mix all kinds of raw materials uniformly and discharge the water in the raw materials) → Go to cold mixing (reduce the temperature of the materials and avoid Blocks and discoloration, cold mixing temperature: 55 ℃.) → Mix well-balanced raw materials according to cooling;

Process 2: Extrusion

Join the twin-screw extruder, carry out heating and extrusion → enter the sheet die head for extrusion molding, the formed sheet passes through the four-roll calender, and the base material develops thickness → paste color film → paste wear layer → cooling → cutting ;

Process 3: UV tempering

Surface UV → tempering (tempering hot water temperature: 80 ~ 120 ℃; cold water temperature: 10 ℃)

Process 4: slitting and slotting + packaging

Slitting → slotting, trimming, chamfering → inspection → packaging
