一、望
1、 Look
望指观其外观，首先是看岩棉芯材颜ω　色是否统一，黄白分列』是否严重;其次是看胶水◎有无结块;最后是含渣量，看有︾无大的矿渣。好的棉岩芯材棉丝细、颜色呈黄、胶水分布均匀、无大量矿渣，整体比较平整，无妨碍使用的破损及污痕。
Looking at its appearance, the first is to see whether the color of rock wool core material is unified and whether the yellow and white separation is serious; The second is to see whether the glue is caked; Finally, the slag content depends on whether there is large slag. The good cotton core material has fine cotton thread, yellow color, uniform glue distribution, no large amount of slag, and is relatively flat as a whole without damage and stain that hinder its use.
二、闻
2、 Smell
闻指听讲△其性能，岩棉板内芯的燃烧性能为不燃，吸湿性为3.9%，热荷重收缩温度为643°，有机物含量为2.9%。
Listening to its performance, the combustion performance of the inner core of rock wool board is non combustible, the moisture absorption is 3.9%, the heat load shrinkage temperature is 643 °, and the organic content is 2.9%.

三、问：
3、 Q:

四、切：
4、 Cut:
切指掂其重量，岩棉的容重一般是80~130kg/m，基于成本和不同的需求，一般用80kg较多，但是100kg以上的岩棉防水防火性能非常强。
According to the weight, the unit weight of rock wool is generally 80 ~ 130kg / m. based on the cost and different needs, 80kg is generally used, but the rock wool above 100kg has strong waterproof and fire resistance.
