Background technique

my country is the world's largest producer of wood-based panels and flooring. In recent years, the industry is still on the rise, and its position in the national economy is becoming more and more important. Cold-pressed veneer is a widely used processing technology in wood-based panel processing, and it is often used for secondary processing of wood-based panel surface decoration. Due to the different types of adhesives used in wood-based panel processing, such as API two-component adhesives, polyvinyl acetate (PVAc), vinyl acetate-ethylene copolymer (EVA) and other adhesives are often used for cold pressure bonding. the

Cold-pressed veneer processing, the internal stress of the plate is small, and the product size is stable. During the processing, after the base plate is coated with adhesive, especially the two-component cold-press adhesive with curing agent, it must enter the press in a short time to obtain pressure, otherwise the glue will start to solidify and affect the bonding quality. Usually, when the board enters the press, the fluidity of the glue is strong, and the substrate and the panel are easily misaligned, which causes difficulties and losses for subsequent processing. If the board is stacked and stacked for cold pressing, the veneer misalignment will also increase. Insufficient local pressure is caused, which affects the bonding strength. the
