The PVC crust foam board production line adopts Celuka technology for foaming, which is mainly composed of counter-rotating parallel twin-screw extruder, sheet die, vacuum setting table, tractor, cutting machine and pusher frame and other auxiliary parts. . Compared with free foaming, the surface layer is not only flat and smooth, it has greater hardness and rigidity of the skin layer, and its mechanical properties are significantly better than that of free foam.
The production process of PVC foam board equipment: raw material ingredients-high-speed mixer-extrusion-foaming-cooling and shaping-spraying-traction-cutting-stacking-inspection-finished product storage
Advertising industry: Screen printing, computer lettering, advertising signboards, signboards.
Other uses: templates, sports equipment, aquaculture materials, seaside moisture-proof facilities, water-resistant materials, art materials, various lightweight partitions.
The main difference between PVC free foam board and PVC skinned foam board:
PVC free foam board generally has a thickness of less than 10mm, and the thickness is adjusted by molding and adjusting the foaming ratio and grinding gap. The thickness of PVC crust foam board is generally between 8mm-30mm, and it needs to be cooled on the surface to crust. The surface hardness is high and it is not easy to produce scratches. It is widely used in cabinets, decoration, building templates, etc. The surface hardness of PVC free foam board is general, and it is generally used in advertising display boards, mounted drawing boards, silk screens, carvings, etc.
