How to judge the drying degree of raw materials of fire retardant board

The drying length of fireproof and flame retardant board raw materials can affect the quality of the whole board, but how to judge the drying degree of raw materials is a very important problem, so how do fireproof and flame retardant board manufacturers judge its drying degree?

  A very direct and simple method is weighing, which is an intuitive method to identify the degree of dryness. The raw materials of fire-retardant boards dried by natural air are heavier than those with high humidity. Then, feeling the temperature by hand is the easiest way to identify. We can also touch the board with more water by hand. It feels cold, so its dryness is relatively poor. We need to pay attention to this problem.

 We can also listen to the sound. If the sound sounds dull, the dryness of fireproof and flame retardant board is better. It will not easily cause problems in future use. We should carefully understand it when we buy it from the manufacturer of fireproof and flame retardant board.
