        合成樹脂瓦質量如何鑒別?

        2018-11-07 10:39:07 AM

          瓦(PVC瓦、塑料瓦、合成樹脂瓦)優劣的方法   樹脂瓦(PVC瓦、塑料瓦、合成樹脂瓦)是國家目前大力倡導與推廣的新一代輕型環保屋面建筑材料,其獨特的性能優勢贏得了建筑界人士的普遍關注與認可,產品市場前景甚為廣闊。 

          為了使消費者對樹脂瓦(PVC瓦、塑料瓦、合成樹脂瓦)產品有一個正確的認識與選擇,下面提供一種簡易鑒別優劣樹脂瓦的方法——稱重量

          優質樹脂瓦:重量約2.4—2.8公斤/平方米(2mm厚度)。

          重量約3——3.5公斤/平方米(2.5mm厚度)。

          重量約4——4.5公斤/平方米(3mm厚度)。

          也就是說優質樹脂瓦的密度大約為1.2~1.4。

          劣質樹脂瓦:同等產品厚度每平方米重量大于上述數值的為劣質樹脂瓦。

          劣質樹脂瓦中添加了大量的重質碳酸鈣及其它填充料。其產品脆性大,易折,低溫抗沖擊力差,耐候性能差,無法保證產品的使用壽命
