When laying technical wood veneer paper, pay attention to the surface of the substrate is smooth, smooth and balanced in structure. What treatment should be done before bonding?
A layer of polyester paint should be applied to the wall first to prevent moisture and mildew. The adhesive liquid that overflows when pasting the veneer should be wiped with a clean towel at any time, especially the glue marks at the seams. If the veneer is beautiful and durable, and it is not easy to foam and warp, it is very important to treat the wall before construction. The wall to be affixed with the technical wood veneer must be smooth and dry, free of dirt and dust. It should also be selected that the relative humidity of the air is lower than 85%, the temperature should not change drastically, and construction in wet seasons and wet walls must be avoided.
Another point is that the construction workers are required to keep their hands and tools highly clean. If there are stains, they should be cleaned with soapy water or detergent in time.
Tech veneer veneer paper heat treatment In the production process of veneer veneer paper, several factors will affect its hot pressing process, so how to strictly carry out hot pressing?
During operation, be careful to move the tech wood veneer to avoid damage. Dirty gloves are not allowed. In the process of assembling the blanks, if the board surface is found to be unclean, it should be cleaned in time and carefully checked when feeding the substrate. If there are defects such as large shavings, missing corners, damage, and sand marks on the board surface, they should be eliminated in time. In addition, for the pressing rollers of the paving machine, the large suction cups for discharging, and the small suction cups for stacking and separation, each conveying roller should be cleaned regularly to prevent the suction cup marks and dust on the board surface, which will cause the product to drop.
It should also be noted that high temperature is conducive to demoulding after pressing, shortening the hot pressing period and increasing production. However, too high a temperature causes the resin to cure with uneven flow, resulting in pinholes on the board surface.
