How to judge the drying degree of Multilayer Board

In order to make the multi-layer plywood more beautiful and prevent it from damp and mildew, it must be heated by high temperature and high pressure. But if the multilayer board is too dry, it will make its expansion dry crack, if too wet it is easy to mold. It can be said that the drying degree of multilayer board raw materials and its product quality has a very close relationship, so to control the drying degree of Multilayer Board. How Dry is the multilayer board? Here's how to judge the dryness of a multilayer board:

First of all, you can weigh, which is a more intuitive way to identify the degree of wood drying, after natural air-drying of the raw material than the humidity of the material. The second easiest way to identify wood is to feel the temperature of the wood with your hand. Wood with a high moisture content feels cold to the touch, whereas wood that is relatively dry does not. On the other hand, if it's a dry, multi-ply material, the sound will be dull, while the opposite material will be crisp.
