SPC floor machine is extruded by extruder and T-die extrusion PVC substrate, with three-roll or four-roll calender, respectively, PVC wear layer, PVC color film and PVC substrate, one-time heating paste, embossed products. The process is simple, close by heat to complete, do not need glue.
SPC floor is made of polyvinyl chloride (divided into pure new material, mixed material, recycled material), calcium powder (classified with stone powder grade) and solvent (the use of chemical grades also use plant solvent food grade).
Process 1: mixing
Automatic metering according to raw material ratio → hot mixing of high-speed mixer (temperature of hot mixing: 125 ℃, It is to mix all kinds of materials evenly, remove the moisture in the materials) → enter the cold mixing (cool the materials, Prevent caking and discoloration, cold mixing temperature: 55 ℃.) → mix evenly by cooling;
Process 2: extrusion
the twin-screw extruder for heating extrusion → enter the sheet die head for extrusion molding, forming the sheet. After four roller calender, the base material is fixed thickness → color film → 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 packing
Cutting → slotting, trimming and chamfering → inspection → packaging
