The veneer process is to melt, unfold and solidify the resin on the melamine decorative paper to form a uniform and closed surface, so what are the requirements?
Appropriate pressure is required first, so as to ensure a good bond between the board and the paper, so that the resin in the melamine decorative paper flows evenly and forms a closed, non-porous surface. The hot pressing temperature then catalyzes the curing reaction of the impregnating resin, which is a favorable condition for accelerated curing. Third, the curing time mainly depends on the curing speed of the impregnating resin, the hot-pressing temperature and the number of layers of impregnated paper in the slab, that is, the time required for the press to reach the specified pressure until the press is turned on.
