There are two types of steel doors, one is called steel-wood interior door, the door is used for interior decoration, and the other is called armored door. The above two kinds of doors are developed from the security door. Many of the crafts are transferred from the security door. The structure is a mixed structure of steel plate and wood, so they are all called steel doors. Introduction to the paint process on steel doors Paint is used as the post-process of steel wood door factory processing, and 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 steel doors. The types of paints are broadly classified into phenolic paints, alkyd paints, polyurethane paints, nitrocellulose paints, polyester paints and PU paints. 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 friendliness are unmatched by other paints. The high requirements for the paint film effect of steel door products are not only the requirements of fine products, but also the embodiment of art culture. Because the quality of paint film determines the performance of the process effect, it affects the artistic charm and cultural connotation of steel doors. On the basis of the same production process, the better the quality of the selected paint, the better the performance of the paint film, and the construction effect is easy to reflect. The paint process is the first factor influencing the pros and cons of steel doors. The selection of the paint process is the most important part of the steel door production process. It is the root of the value of the steel door. There is no suitable process to match the appearance of the wood value. The value of the steel door is not reflected. If the construction process and quality requirements of the paint are the performance of the cultural and artistic value of the steel door products, then the performance choice of the paint is the specific requirements of the actual function of the steel door products. Therefore, in the choice of steel doors, paint is one of the factors that must be considered, it directly affects the texture, feel, moisture, environmental protection, durability, yellowing and other issues. Moreover, there are two main methods of painting the steel door and steel door: baking varnish and PVC veneer.
