SPC Rigid Core Plank Flooring production process
Process: 1. Mixing
Automatic measurement according to the raw material ratio → high-speed mixer hot mixing (hot mixing temperature: 125 ° C, the function is to mix the various materials evenly to exclude moisture in the material) → enter the cold mixing (To cool the materials, prevent agglomeration and discoloration, cold mixing temperature: 55 ℃. ) → Mix the homogeneous materials by cooling.
Process: 2. Extrusion
Add a twin-screw extruder and perform heating extrusion → enter the sheet die extrusion molding. The formed sheet passes through a four-roll calender and the base material is set to a thickness → color film → abrasion resistant 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
Slitting → Slotting, Trimming, Chamfering → Inspection → Packaging
The components of PVC Stone Effect Vinyl Sheet Flooring are PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, and the main components are polyvinyl chloride and stone powder. From the bottom to the surface, the plastic floor is composed of a PVC-based color film decorative paper, a wear-resistant layer, and a UV coating. Rigid Core SPC Flooring is an extruder combined with a T-die to extrude the PVC substrate. The three-roller or four-roller calender is used to apply the PVC wear-resistant layer, the PVC Commercial Vinyl Flooring Planks film and the PVC substrate to the heat-applied and embossed product. , The process is simple, the lamination is completed by heat, and no glue is required. The physical index of SPC Durable PVC Vinyl Flooring Plank is stable and reliable, and the chemical index conforms to international and national standards.
