Problems solved by technology

[0003] The traditional pulp product processing technology is to vacuum dehydrate the pulp after being molded and then transfer it to the drying section for drying. Due to the limitation of the pulp material, the tensile, compressive and ring compressive strength of the product is low, and the load-bearing capacity is limited. , mainly used in the field of pulp products for lighter items

Abstract

The invention relates to a composite paper pulp product molding processing method and a paper pulp product thereof. The method comprises the following steps: 1) pre-pressing a reinforcing rib net or a thin steel plate into a set shape for later use according to the size of the paper pulp product; (2) placing the reinforcing rib net or the thin steel plate into a forming mold in a paper pulp molding machine, sinking the forming mold into a pulp pool, and vacuumizing, sucking pulp and dehydrating; and 3) after a wet mold is formed, transferring the wet mold to a drying mold for shaping and drying. The paper pulp product prepared by the invention not only has certain bearing capacity and toughness, but also has the characteristics of recyclability, economy, low cost, environmental protection and the like.

Description

technical field [0001] The invention relates to a processing method of a pulp product, in particular to a molding processing method of a composite pulp product and the pulp product thereof. Background technique [0002] Pulp products are made of pulp with a certain concentration, adding appropriate amount of chemical additives in the molding machine to make the fibers evenly distributed on the surface of the mold by vacuum or pressure, so as to form a wet paper mold base with the proposed geometry and size, and then further dehydration Demoulding, drying and shaping the finished product. [0003] The traditional pulp product processing technology is to vacuum dehydrate the pulp after being molded and then transfer it to the drying section for drying. Due to the limitation of the pulp material, the tensile, compressive and ring compressive strength of the product is low, and the load-bearing capacity is limited. , mainly used in the field of pulp products for lighter items. ...
