The so-called moisture-proof board is to add a certain proportion of moisture-proof particles in the production process of the substrate, also known as melamine board, which can greatly reduce the degree of water expansion of the cross-section of the board. Generally, the moisture-proof panels produced by regular plate manufacturers have obvious marks to distinguish them from ordinary plates. For example, the well-known European love board is made of green and red pigments in the moisture-proof board. Different colors indicate different moisture-proof properties. The kitchen countertops with higher moisture-proof requirements can choose the red board with better moisture resistance. The green door can be selected for the door panel.
The ordinary substrate and the moisture-proof substrate were simultaneously immersed in water, and the expansion of the ordinary plate was changed for two hours, and the expansion rate of the ordinary plate was significantly higher than that of the moisture-proof plate. The moisture barrier has good moisture resistance and is suitable for kitchen furniture and bathroom furniture.
