Inspection and quality control of pet wood-based panel and UV wood-based panel

Introduction: pet plate is a popular plate decoration material in the market in recent years. The scientific name of pet is polyethylene terephthalate (PET). The PET film has high flatness, strong toughness, good stiffness and stable size. It is suitable for plate surface decoration.

Which is better, pet door panel or UV door panel? Strictly speaking, there is no good or bad difference between the door panels of the two categories, mainly due to the difference in the decorative materials on the surface of the plate.

Pet plate is a popular plate decoration material in the market in recent years. The scientific name of pet is polyethylene terephthalate (PET). The PET film has high flatness, strong toughness, good stiffness, stable size and is suitable for plate surface decoration. The mineral water bottles we drink in our daily life are made of PET material. The pet plate is mainly made by pressing a layer of PET film on the printed paper on the surface of the plate, because the PET film is transparent and colorless. Therefore, the color of PET sheet mainly depends on the color of decorative paper on the surface of the sheet. The surface hardness of PET film can generally reach 2h, and the scratch resistance is good. Moreover, the PET film has certain toughness, so it is not easy to collapse during the blanking and cutting process. Of course, if the pressure between the PET film and the substrate is not uniform or the adhesive quality is not good, there will be adhesion in the later stage, and the surface of the plate will bulge.

Pet plate UV plate is a kind of decorative material that is UV roller coated on the surface of the plate and then UV light cured. Under the current environmental protection situation, UV coating, as an environmental protection material, has developed rapidly in recent years. It has high solid content, less volatile matter, high production efficiency and stable quality. It is a mature industrial product in the current decoration market! At present, the surface hardness of UV plate is generally between 2H and 3h, and the hardness of UV plate can also reach 4H to 5h, but it is not suitable for customized door panels in the whole house. Because the hardness is too high, edge collapse will occur during blanking. Intuitively, first of all, the base materials for pet and UV boards are mainly density boards. Of course, the base materials can also be multi-layer boards and particleboards. In contrast, the surface flatness of density boards is higher than that of solid wood multi-layer boards and particleboards. Therefore, density boards are the common base materials for pet and UV boards. From the perspective of environmental protection, most density boards are E1 grade materials, and E0 grade materials are less in the market. Therefore, the environmental protection of using density board as the base material is inferior to that of solid wood multilayer board and particleboard.

In terms of flatness, the flatness of pet plate is better than that of UV plate, mainly because the flatness of UV plate mainly depends on the flatness of plate. If the flatness of the substrate selected for the UV panel is not high, there will be surface collapse in the later stage. From the side, the UV panel will appear orange peel. This is mainly for high light UV products, and Matt products do not have high requirements for substrate flatness. In terms of price, the background color of pet plate and UV plate is decorative paper, and the price of pet plate is dozens of yuan higher than that of UV plate. Of course, if the UV plate is pasted with wood veneer, the price of the plate also depends on the price of the wood veneer itself.

In terms of yellowing resistance, pet door panels and UV door panels have good yellowing resistance indicators.

In general, the pet door panel and UV door panel are rich in color, high in flatness, and high in gloss (bright light) and matte (skin feeling), which are especially suitable for the application of the minimalist light luxury style customized by the whole house.
