        合成树脂瓦质量如何鉴别?

        2018-11-07 10:39:07 AM

          瓦(PVC瓦、塑料瓦、合成树脂瓦)优劣的方法   树脂瓦(PVC瓦、塑料瓦、合成树脂瓦)是国家目前大力倡导与推广的新一代轻型环保屋面建筑材料,其独特的性能优势赢得了建筑界人士的普遍关注与认可,产品市场前景甚为广阔。 

          为了使消费者对树脂瓦(PVC瓦、塑料瓦、合成树脂瓦)产品有一个正确的认识与选择,下面提供一种简易鉴别优劣树脂瓦的方法——称重量

          优质树脂瓦:重量约2.4—2.8公斤/平方米(2mm厚度)。

          重量约3——3.5公斤/平方米(2.5mm厚度)。

          重量约4——4.5公斤/平方米(3mm厚度)。

          也就是说优质树脂瓦的密度大约为1.2~1.4。

          劣质树脂瓦:同等产品厚度每平方米重量大于上述数值的为劣质树脂瓦。

          劣质树脂瓦中添加了大量的重质碳酸钙及其它填充料。其产品脆性大,易折,低温抗冲击力差,耐候性能差,无法保证产品的使用寿命
