Performance characteristics of PVC Co-Extruder foam Plate Extruder is a newly developed foaming plate unit of Shengkarei plastic machine. through the co-extrusion machine, the rigid PVC layer of the composite surface layer is not foamed. The surface hardness of foamed sheet is greatly improved, and the performance of the unit is stable and the technology is ahead of the domestic level. Application of PVC co-extruded foam plate: the surface of three-layer co-extruded PVC foam plate is as smooth as mirror and has high surface hardness. It has the properties of sound insulation, sound absorption, heat insulation, heat preservation and so on. The plate has flame retardancy and high safety. Moisture proof, mildew proof, do not absorb water, shock protection effect is good. Good weather resistance, color can remain unchanged for a long time, not easy to age. Low density, light texture, storage and transportation, convenient construction. The use of general wood processing tools can be constructed. Can carry on drilling, saw, nail, planing, adhesion and other processing technology. It can be used for hot forming, heating, bending and folding. Can be welded according to the general welding procedure, can also be bonded with other PVC materials. Used in transportation ships, aircraft, passenger cars, train carriages, roof, box core layer, internal decoration board. Building decoration industry building exterior wallboards, interior decoration panels, residential, office, public places building cubicles, commercial decorative shelves, dust-free room panels, ceiling panels, family kitchen cabinets, hanging cabinets and homes. Through paint printing, film and hot pressing equipment, you can produce imitation wood products. PVC three-layer co-extrusion foam plate extruder basic introduction three-layer co-extrusion PVC foam plate production line is composed of conical twin-screw extruder, plate die, setting table, traction and cutting auxiliary machine. The extruder adopts specially designed screw, which greatly improves the plasticizing effect of PVC and the rigidity of the product. The product has a good application prospect.
