Abstract

The invention discloses a surface manufacturing process of a pulp molded product, comprising a surface manufacturing device of a pulp molded product and a surface manufacturing process of a pulp molded product. The surface manufacturing process of a pulp molded product comprises the following steps: Step 1. mold selection; Step 2, object placement; Step 3, ink printing; and Step 4, placement management. By printing of paper plastic, the paper plastic undergoes the processes of raw material beating, burdening, compression molding, drying and shaping. The water content of the paper plastic is usually between 2wt% and 5wt%. If the surface moisture of the paper plastic is too high, the paper plastic forming effect is poor, the ink cannot be well printed on the paper-plastic surface, and the printed pattern will be blurry. 1kg=0.1Mpa=one standard atmospheric pressure. The paper plastic surface can withstand limited pressure. If the atmospheric pressure is too high, the paper plastic will bebroken, and the yield of printing is affected. Without affecting the change of the paper plastic shape, higher pressure is better.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a surface processing technology of pulp molded products. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain degree of fluidity. paste-like adhesive. [0003] When ink patterns are printed on paper-plastic molds, paper-plastic objects tend to shift during the printing process, thereby affecting the quality of ink printing and causing greater economic losses. [0004] Therefore, it is necessary to invent a surface processing technology for pulp molded products to solve the above problems. Contents of the invention [0005] The purpose of the present invention is to provide a surface processing technology for pulp molded products. The semi-finished paper and plastic p...
