Rock wool composite board is widely used in housing construction, especially in some public buildings and mobile houses. When purchasing, we should pay attention to the selection of qualified products, so as to have quality assurance. Then how should we evaluate the quality of products when purchasing? So I will teach you.

　　，基质的厚度和腹膜的厚度

　　First of all, the thickness of the matrix and the thickness of the peritoneum

　　岩棉复合板是由基质和颜色腹膜或涂层,我们必须考虑衬底的厚度和腹膜涂料、厚衬底,质量相对越好,膜的厚度根据实际生产的需要定制的,生命的颜色钢瓦、衬底的厚度是非常重要的。市场上有这样的商家，为了提高利润，会减少承印物的厚度，增加膜的厚度来欺骗客户，这大大降低了彩钢板的使用寿命。

　　Rock wool composite board is composed of substrate and color peritoneum or coating. First of all, we must consider the thickness of substrate, peritoneal coating and thick substrate. The quality is relatively better. The thickness of membrane is customized according to the actual production needs. The thickness of life color steel tile and substrate is very important. There are such businesses in the market, in order to improve profits, they will reduce the thickness of substrate and increase the thickness of film to cheat customers, which greatly reduces the service life of color steel plate.

　　检查岩棉复合板的漏边

　　Check the edge leakage of rock wool composite board

　　当我们看到产品时，对暴露在外的钢板颜色进行检查，看其结晶部分是否细小，是否有明显的杂质，如果结晶部分细小，则说明质量上乘。

　　When we see the product, check the exposed steel plate color to see whether the crystal part is small and whether there are obvious impurities. If the crystal part is small, it means the quality is excellent.

　　听声音

　　Listen to voice

　　用手指或用硬物敲击彩钢板，彩钢板材料若差，则声音沉闷，金属声不明显，材料较好的彩钢板金属声相对较大，清晰。

　　If the color steel plate material is poor, the sound is dull and the metal sound is not obvious. The metal sound of the color steel plate with better material is relatively large and clear.

　　我相信上面的介绍也清楚如何识别岩棉复合板的质量,事实上,我们应该更加注意产品细节检查期间,为了防止假冒伪劣产品的购买,影响项目的质量是不值得的损失。

　　I believe that the above introduction is also clear about how to identify the quality of rock wool composite board. In fact, we should pay more attention to the product details during the inspection. In order to prevent the purchase of fake and inferior products, it is not worth the loss to affect the quality of the project.
