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.

　　首先，基質的厚度和腹膜的厚度

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

　　巖棉復合板是由基質和顏色腹膜或涂層,我們首先必須考慮襯底的厚度和腹膜涂料、厚襯底,質量相對越好,膜的厚度根據實際生產的需要定制的,生命的顏色鋼瓦、襯底的厚度是非常重要的。市場上有這樣的商家，為了提高利潤，會減少承印物的厚度，增加膜的厚度來欺騙客戶，這大大降低了彩鋼板的使用壽命。

　　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.

　　檢查巖棉復合板的漏邊

　　Check the edge leakage of rock wool composite board

　　當我們看到產品時，對暴露在外的鋼板顏色進行檢查，看其結晶部分是否細小，是否有明顯的雜質，如果結晶部分細小，則說明質量上乘。

　　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.

　　聽聲音

　　Listen to voice

　　用手指或用硬物敲擊彩鋼板，彩鋼板材料若差，則聲音沉悶，金屬聲不明顯，材料較好的彩鋼板金屬聲相對較大，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.

　　我相信上面的介紹也清楚如何識別巖棉復合板的質量,事實上,我們應該更加注意產品細節檢查期間,為了防止假冒偽劣產品的購買,影響項目的質量是不值得的損失。

　　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.
