Abstract
An energy-saving production process method for rapid drying and dewatering of paper-plastic products, which is applied to production of paper-plastic products, and mainly comprises a cold extrusion press station (2) which is independent and is arranged between a pulp suction forming station (1) and a hot-press shaping station (3); the cold extrusion press station (2) is provided with a top mold and a lower mold (21, 22) which can form a mold closing mold closing gap according to the shape and size of a product, the mold closing mold closing gap is used to first press a primary product to discharge water of about 30% to 50%, and then send same to the hot-press shaping station for continuous dewatering to below 3% to form a paper-plastic product. The paper-plastic product produced by using the present production process can shorten the production time and reduce the consumption of heat energy for drying.
