It is said that the quality of wood plastic panels is good, indeed, but everything has defects. The same is true for the well-known wood plastic panels. Today we will discuss the main problems and solutions of wood plastic panels.
The main problems and solutions of wood plastic panels are as follows:
The first problem is that the moisture content in wood plastic materials is too high. Wood plastic materials often have a porosity of 16-21%, which causes them to break easily and be easily damaged by microbial contamination. The solution is to control and reduce the water content in the wood plastic fiber composition to the greatest extent, while not exceeding the necessary temperature and speed in the production and manufacturing process.
The second problem is that the amount of antioxidants is too low, causing wood plastic panels to be easily oxidized, and the surface layer is easy to fall off. The solution is simple: add an appropriate amount of antioxidant to the wood plastic material. The appropriate amount of oxidant refers to the critical reading value induced by the oxidation of the wood plastic product, which is detected and read by the differential heat scanner.
The third hidden danger is the shrinkage of wood plastic materials after they are manufactured. This is the biggest problem in the rapid cooling process, especially on hollow boards. Simple solutions include allowing wood plastic panels to have sufficient time to be placed in the production workshop, cooling and shrinking; when it is not necessary, do not produce wood plastic panels at high speed.
The fourth common problem is the fading of the product due to excessive sanding and insufficient pigments. Manufacturers can deal with this problem by reducing polishing. In addition, the necessary amount of inorganic pigments, such as iron oxide, can be determined and added.
Finally, the surface of many wood plastic panels is too smooth is the most dangerous problem. In a humid environment, wood plastic panels are more slippery than ordinary wood panels, and they are too smooth even in dry conditions. It is suggested that manufacturers can help avoid this problem by printing texture on the surface of the board, changing the plastic content to increase traction, and using coatings provided by professional companies.
The main problems and solutions of wood plastic panels are the issues that manufacturers need to pay attention to, and they can also make it easy for consumers to distinguish when buying wood plastic panels.
