The thickness of the PVC foam board introduced by the PVC foam board manufacturer is different, the configuration of the mold is different, the length of the mold and the flat section of the compression ratio are different, and the thick layer of the mold foam layer is thicker, so there will be elastic deformation space, general design. N in the mold has a flattened section with a longer compression and a larger compression to increase the melting pressure and the size of the foamed board is thin, the elastic space is small, but the rigidity is large. The pressure of PVC decorative board manufacturers is divided into pre-pressing and hot pressing. When using a linerless system, the plate must be pre-pressed. The pre-pressure relief of PVC decorative parts will not damage the plate during the advancement of the hot press. The hot pressing process is a key process that determines the production capacity and output of the enterprise. The hot pressing equipment commonly used in the wood-based panel industry is mainly a multi-layer hot pressing machine. After the PVC decorative board * is finally discharged from the hot press, through the cooling and moisture balance stages, the specific requirements of the PVC decorative board manufacturer on the board, namely sawing, sanding, hard fiberboard heat treatment and moisture conditioning treatment. As an interior decoration, PVC foam board does not need to resist aging. If you want to do outdoor anti-aging, outdoor aging is very fast and the wall damage is very serious. Gradually replace hard PVC exterior wall decorative boards, wood-fiber cement exterior wall decorative boards, etc. The above is the introduction of PVC foam board, I hope to help everyone.
