1995年法国邓迪克斯公司研制出一种能抗老化的透明聚氯乙烯屋面瓦。这种瓦解决了以往80年代透明聚氯乙烯屋面瓦不抗紫外线照射的缺点,而兼有过去该种屋面瓦具有的性能:如透光率高出玻璃钢瓦的3倍,抗拉强度、伸长率、弹性模量、导热系数满足屋面材料使用的要求。由于新研制的屋面瓦经过了一定的技术处理,瓦的双向拉伸冲击强度在1200MJ/m~2以上,是聚氯乙烯屋面瓦的2倍,瓦的耐火度为1级,它在火灾中难以熔化、流
In 1995, French Dundee company developed a transparent polyvinyl chloride roof tile that can resist aging. This tile solves the shortcomings of transparent PVC roof tiles that were not resistant to ultraviolet radiation in the past in the 1980s, and it has both the properties of the roof tile in the past: such as light transmittance higher than 3 times of glass fiber tile, tensile strength, elongation Long rate, elastic modulus and thermal conductivity meet the requirements for the use of roofing materials. Since the newly developed roof tile has undergone certain technical processing, the two-way tensile impact strength of the tile is more than 1200 MJ/m~2, which is twice that of the PVC roof tile, and the refractoriness of the tile is one, which is in the fire. Hard to melt, flow
