Operation: 1. Mixture
According to the raw material proportioning automatic metering → hot mixing of high-speed mixer (hot mixing temperature: 125 ℃, the function is to mix all kinds of materials evenly and remove the moisture in the materials) → put into the cold mixture (to cool the materials, prevent caking and discoloration, cold mixing temperature: 55 ℃). → cool and mix materials evenly;
Action 2: extrude
Add twin-screw extruder, heat extrusion → enter sheet molding, forming sheet
The material passes through four roller calender, the base plate is fixed thickness → colored film → paste wear-resistant layer → cooling → cutting;
Project 3: UV tempering
Surface UV → tempering (tempering hot water temperature: 80-120 ℃; cold water temperature: 10 ℃)
Procedure 4: slotting + Packaging
Slitting → slotting, trimming, chamfering → inspection → packaging
