  In the lamination of the technical veneer paper, the cold-hot-cold hot pressing process can be adopted, which can effectively avoid the high temperature in the early stage of hot pressing leading to partial curing of melamine resin.

  Pay attention to select a single layer panel with a flatness that meets the requirements to remove surface impurities for use; The melamine paper is placed on the panel, and the cold-hot-cold hot pressing process is adopted. When the slab enters the press, the hot plate temperature is maintained at 40 degrees to avoid local curing of the resin. Then, the temperature is heated and pressurized, and the temperature is controlled at 140 degrees, the pressure is maintained at 13Mpa, and the maintenance time is 150s. In this process, the stainless steel wire mesh can play a cushioning role, and can make the veneer pressed to form a certain fiber lines, not warping, stainless steel template can ensure the overall flat sheet, the surface of the sheet after pressing wood feeling, and copper wire insulation pad plays a role in heat conduction and heat preservation, improve the quality of the veneer.

  Moreover, the high temperature in the later stage causes poor curing, and the consequences of paper-board separation greatly improve the surface gloss of the plate and improve the quality of the product.
