空心塑料片材或空气夹心片材正在成为一种新型建筑材料。这种新型材料是由中间有蜂巢型或口琴型支撑物的两种塑料片材组成的结构板条,所用的塑料材料是聚碳酸酯和聚甲基丙烯酸甲酯,该复合板条重量轻、强度高。这种板条作为透明材料使用,能使太阳光扩散且透明度高,并具有热绝缘性。目前正在开发作为建筑材料的新用途,它作为屋顶板可用于建造日光浴室等。 Hollow plastic sheet or air sandwich sheet is becoming a new building material. The new material is a structural strip consisting of two plastic sheets with a honeycomb or harmonica support in between. The plastic materials used are polycarbonate and polymethyl methacrylate. The composite strip is lightweight, high strength. The slats are used as a transparent material, can diffuse sunlight and have high transparency, and have thermal insulation properties. New uses are currently being developed as building materials, which can be used as roofing panels to build solariums.
