Energy-saving production process method of paper-plastic product capable of being quickly dried and dehydrated

Abstract

The invention relates to an energy-saving production process method for a paper-plastic product capable of quickly drying and dehydrating, in particular to a process application applied to the production of the paper-plastic product, which mainly comprises an independent cold extrusion station arranged between a pulp suction forming station and a hot-pressing shaping station, the cold extrusion station is provided with an upper mold and a lower mold which can form a mold closing gap according to the shape and the size of a product, the mold closing gap is used for firstly squeezing the primary blank to discharge about 30-50% of water, and then the primary blank is conveyed to the hot-pressing shaping station to be continuously dehydrated to be less than 3% to form a paper-plastic product; the paper-plastic product produced by the invention can shorten the production time and reduce the consumption of drying heat energy.

Description

technical field [0001] The invention relates to a production process of a paper-plastic product, in particular to a production process of an energy-saving, fast-drying and dehydrating paper-plastic product. Background technique [0002] With the deepening and demand for the concept of environmental protection, the technical improvement of the production process of degradable and recycled products is becoming more and more important, especially the paper-plastic products made of herbal plant fibers are non-toxic, degradable, The characteristics of recyclability and remanufacturing have become the vanguard of environmentally friendly products, and the production process of paper and plastic products is nothing more than continuous production processes such as pulp suction molding, hot pressing and trimming, among which how to reduce heat consumption and Reducing the time for hot-pressing and setting is a technical field that the technicians in the paper-plastic product industr...

Problems solved by technology

[0004]Furthermore, if the extrusion die 92 is used to directly press the initial product in the slurry suction die 91, only dehydration of the press is considered and the clamping gap after extrusion is not calculated (that is, the thickness of the embryo product after being extruded), it is easy to cause the thickness of the semi-dry and wet embryo product M to be too thick or too thin, and an improper thickness will cause a high defect rate of the embryo product after the finished product; the semi-dry and wet embryo product If the thickness of the product M is too thick, the macular phenomenon will occur on the paper-plastic product. If the thickness of the semi-dry and wet embryo product M is too thin, the bursting resistance, folding resistance and strength of the paper-plastic product will be too low, and it will also cause the appearance of the finished product. The uneven and obvious texture is a known defect of using cold press dehydration technology as the production method of paper and plastic products, which also prevents the production efficiency from being improved and increases the production cost.
