Environment-friendly shoe insole board production process

Abstract

The invention discloses an environment-friendly shoe insole board production process. The environment-friendly shoe insole board production process includes production steps: feeding, by weight, 38-42% of mug-long fiber paper pulp, 28-30% of wood powder and 28-30% of toilet paper pulp into a hydrapulper for mixing, and using a pulp pump to pump the mixed pulp into a pulp tank; feeding the mixed pulp into a heat dispersion system for heating at 80-100 DEG C for secondary defibering, so that paper pulp fibers can be saturated in water absorption, and speed increase of a production line is facilitated; feeding paper pulp processed by the heat dispersion system into a pressure screen system for third-time defibering; dyeing the paper pulp processed by the pressure screen system, uniformly mixing dye and pulp, and feeding the paper pulp into a paper maker for conventional production to obtain a shoe insole board. Finished paper sheets made by the process are free of impurity dots on the surfaces so as to be more attractive than traditional paperboards with residual ink dots.

Description

technical field [0001] The invention relates to the field of paper production, in particular to an environmentally friendly production process for midsole plates for shoes. Background technique [0002] At present, manufacturers who use waste paper to produce shoe midsoles mainly use white-core cardboard, yellow-core cardboard and various cigarette box cardboard. Since most manufacturers invest less in pulping equipment, and there is a lot of sewage generated from the treatment of various cardboards (some are coated on the surface of the cardboard, some are printed, and some contain heavy metals), especially the sewage contains mud body cannot be recycled. Traditional manufacturers have two ways to deal with the mud-like body: ① Sewage recycling. After the mud-like body is made into slurry, the water permeability of the paper will be reduced during the paper forming process. After a period of recycling of sewage production, When the water permeability drops to a certain le...

Since most manufacturers invest less in pulping equipment, and there is a lot of sewage generated from the treatment of various cardboards (some are coated on the surface of the cardboard, some are printed, and some contain heavy metals), especially the sewage contains mud body cannot be recycled

Traditional manufacturers have two ways to deal with the mud-like body: ① Sewage recycling. After the mud-like body is made into slurry, the water permeability of the paper will be reduced during the paper forming process. After a period of recycling of sewage production, When the water permeability drops to a certain level, paper crushing will occur, resulting in the inability of the latex to penetrate during sizing, and the paper will not operate normally, which will have a great impact on the quality of the product; Very serious damage to the ecological environment

[0003] At the same time, traditional paper-making materials discharge too much, and paper mills cannot handle them perfectly. The use of this material has very poor stability on the air permeability, stiffness and folding resistance of the product.
