塑钢门窗,俗称“塑裹钢”,是继木、钢、铝合金之后发展的第四代新型节能低耗建筑门窗。 一、塑钢门窗的始原与性能 塑钢门窗制作主要材料是塑料异型材,采用PVC加十八种添加剂改性以后,内裹各种规格的钢制作而成的。这种外塑内钢的门窗,1952年产生于德国,并在1959年的杜塞尔多夫塑料展览会上首次展出。由于它具有质轻、抗冲、耐腐蚀、隔音、保暖、密封性能好、膨胀系数低、绝缘、阻燃、不
Plastic steel doors and windows, commonly known as “plastic wrap steel”, is the fourth generation of new energy-saving and low-cost building doors and windows developed after wood, steel and aluminum alloy. First, the beginning of the plastic steel doors and windows and performance Plastic steel doors and windows production of the main material is a plastic profile, using PVC plus 18 kinds of additives modified, wrapped in a variety of specifications made of steel. The doors and windows of the outer plastic inner steel were produced in Germany in 1952 and were first exhibited at the 1959 Düsseldorf Plastics Fair. Because of its light weight, impact resistance, corrosion resistance, sound insulation, warmth, good sealing performance, low expansion coefficient, insulation, flame retardant, no
