PVC共擠發(fā)泡板內(nèi)外層為硬質(zhì)PVC，芯層為PVC發(fā)泡層，能大大降低設(shè)備成本和配方成本（和真結(jié)皮發(fā)泡設(shè)備相比)，產(chǎn)品質(zhì)量和各方面參數(shù)都接近或優(yōu)于真結(jié)皮發(fā)泡板（1.22m制品寬，5~20mm厚，密度~O.5g/cm，表面強(qiáng)度:50~75洛氏硬度），同時(shí)制品表面可經(jīng)過燙印，印刷或貼膜，獲得不同樣式和圖案，此外在有些需要折邊的應(yīng)用場合，經(jīng)過熱彎曲處理可以達(dá)到應(yīng)用要求。
設(shè)備組成;由擠出機(jī)，分配器，模具，定型模板，冷卻架，牽引機(jī)，切割機(jī)，堆料臺(tái)組成，設(shè)備精度高，操作方便。
Structure of the PVC foamed board extrusion line: Outer surface layer is rigid PVC and inner layer foamed PVC, it feature in low machine andformula cost compared with PVc skinned foamed plate, meanwhile, the product and paramelers( 1.22m width with 5-20mm thicknessproduct dimension, -0.5glcm3 density 50-75 Rockwell hardness) are all qual of better.Aiso,the surface of the product can be printed orlaminated to get different patterns.
The machine consists main extruder & co-extruder, distributor, calibrator moulding block,cooling rack, haul off cutter & stacker.
