Good wood drying The key role of the wood drying process in the production of raw wood doors is mainly reflected in three aspects: First, the dry quality of the wood determines the yield of the wood. Especially for precious wood species, it is of great significance. Second, the dry quality of the wood determines the surface quality of the finished wood door. Third, the dry quality of the wood is the determining factor in determining whether the wood door will warp and deform. Therefore, in the production of the original wooden door, the drying process of the wood should be strictly controlled first, and it is necessary to prevent the cracking deformation in the drying of the wood, and to make the water content uniform, and to achieve the method of changing the moisture content of the wood by using the standard: Dry, that is, dry after drying. Reasonable selection of tools In the production of the original wooden door, the processing and modeling of the original wooden door is mainly realized by some forming tools, so the reasonable selection of the cutting tool has a direct determining effect on the processing precision and decorative effect of the original wooden door. On the other hand, the cutting performance of the tool also has a great influence on the surface quality of the original wood door. Therefore, the rational selection of tools is very important in the production of original wood doors. PU paint is best used for painting Paint is used as a post-process for the processing of the wooden door factory. Its advantages and disadvantages directly affect the final use effect. At the same time, the cost of paint is also one of the largest parts of the cost of wooden doors. The types of paint are roughly classified into phenolic paint, alkyd paint, and nitrocellulose paint. Original wood door, unsaturated polyester paint and PU paint. Among them, phenolic paint and alkyd paint are basically eliminated in the decoration due to the poor texture and adhesion of the paint film. A large number of PU paints used in lacquer, polyester paint and high-grade furniture are used. Due to the simple construction and suitable for manual operation, the nitrocellulose lacquer is used by most hand-decorated woods, but its paint film is thin, the hand feel is not good, and the effect is not satisfactory. Polyester paint is relatively thick, but its thinner contains helium when it is volatilized, and the film hardness is slightly weaker. The most ideal is PU paint. PU paint not only has the thick paint film of polyester paint, but also has strong adhesion and good transparent layer. At the same time, its good sealing property also plays an important role in the moisture-proof of wood. Hardness, durability, yellowing resistance and environmental protection are unmatched by other paints, so it is widely used in high-grade wood door painting and becomes one of the main coating materials.
