In the production and application of multi-layer board manufacturers' products, sometimes the surface of the material will bulge and be uneven, which affects the appearance and use effect of the board. It is necessary to understand the reasons clearly in order to take timely measures to deal with it.
There are many reasons for the bubbling of plywood. It may be that the raw materials are unqualified, the quality is poor, and the surface smoothness of the substrate is relatively poor, which can easily cause bubbling in the finished multi-layer board. It may also be caused by the poor quality of the veneer material. Some materials do not have the necessary waterproof performance. When used, some foreign air will penetrate, which will cause this problem that should not have occurred. Or it may be caused by the immature processing technology and the non-standard process. If the fit between the board and the veneer is not in place, then the bubbling is very likely to occur.
Improper terminal use can also cause bubbling of the products of multi-layer board manufacturers. This situation will also occur when the temperature and humidity are in an unsuitable condition. We need to know more about it to make the board use better.
