Basic performance and installation requirements for HPL plywood multilayer press
Dec 07, 2018

The heat transfer performance, mechanical strength and stiffness of the HPL plywood multi-lamination machine will directly affect the quality and output of the product. In addition, the processing accuracy is different, and the actual output will be different. The temperature of each hot plate and its heat transfer should be uniform to make the pressed slab heat evenly.

In fact, the HPL plywood multi-layer laminator should first have sufficient strength and rigidity, and can withstand the thermal stress caused by the high temperature change. The platen and the lower surface of the hot plate have sufficient parallelism and the flatness of the surface. Roughness, heat medium flow resistance in the pressure plate hole is small and so on. The inside of the press needs to process a lot of holes according to certain requirements, and after it is plugged and welded, a specific form of circuit is formed for heating the hot plate and the slab through the saturated steam.

In addition, it should be ensured that the HPL plywood multi-layer laminator is installed reasonably, especially whether the loop form of the hot plate heating tunnel is reasonable, which plays an important role in improving the quality of the hot press and shortening the hot pressing time. The temperature difference of the surface of the hot press is small, and the quality of the obtained product is good to a certain extent, so that the rigidity, strength and weakening strength of the hot plate can be reduced due to drilling, and the heat medium can be reduced. Flow resistance in the tunnel.
