聚氯乙烯低发泡挤出异型材,是现代建筑中的新型建筑材料之一。它具有木材的观感、手感和两次加工性,并能取代部分木质型材,及实心的聚氯乙烯型材。用挤出法生产的聚氯乙烯低发泡型材耐腐蚀、不会生锈,因此很少需要维修。低发泡异型材自装饰性强,表面不需要经常涂装,并与木材相仿,能锯、能刨、能钉,强度尚好,价格不高。其发泡的主要 PVC low-foam extrusion profile is one of the new building materials in modern architecture. It has the look, feel and twice-processability of wood and can replace some wood profiles and solid PVC profiles. PVC low-foaming profiles produced by extrusion are resistant to corrosion and do not rust, so they rarely require maintenance. The low-foaming profile has strong self-decoration, the surface does not need to be coated frequently, and is similar to the wood, and can be sawed, planed, nailed, the strength is still good, and the price is not high. Its main foaming
