一、望
1、 Look
望指觀其外觀，首先是看巖棉芯材顏色是否統一，黃白分列是否嚴重;其次是看膠水有無結塊;最后是含渣量，看有無大的礦渣。好的棉巖芯材棉絲細、顏色呈黃、膠水分布均勻、無大量礦渣，整體比較平整，無妨礙使用的破損及污痕。
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、聞
2、 Smell
聞指聽講其性能，巖棉板內芯的燃燒性能為不燃，吸濕性為3.9%，熱荷重收縮溫度為643°，有機物含量為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、問：
3、 Q:
問指問詢其基本參數：
Asking refers to asking about its basic parameters:
構成材料：彩鋼板、巖棉
Constituent materials: color steel plate, rock wool
巖棉夾芯板密度：巖棉
Density of rock wool sandwich board: rock wool
熱導系數：
Thermal conductivity:
巖棉板工作溫度：80(℃
Working temperature of rock wool board: 80 (℃)
規格：950、
Specification: 950
四、切：
4、 Cut:
切指掂其重量，巖棉的容重一般是80~130kg/m，基于成本和不同的需求，一般用80kg較多，但是100kg以上的巖棉防水防火性能非常強。
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.
