First, look at the package labels. Generally speaking, the high-quality A-class fire-proof insulation board produced by the regular manufacturer is packaged regularly, and the packing marks are standardized. It will be clearly indicated on the marks: the name of the manufacturer, the trademark, the product mark, the date of production or the batch number, as well as the matters needing attention in storage and transportation.
Next is looking at products. This can be seen through the use of eye to see the smoothness of the product surface, and then look at the two sides of the color steel plate. We must check the core of the rock wool again and distinguish the difference between rock wool and mineral wool correctly. Rock wool is a filament pressed by basalt, which contains a small amount of dolomite. The mineral wool is of low value, no basalt or only 30% of the material under high temperature.
