Description

Production system of bleaching cream paper

Technical Field

The invention belongs to the technical field of papermaking, and particularly discloses a production system for bleached cream paper.

Background

Creams are a description of the state of matter, which has been less viscous than a gel and more viscous than an emulsion. Along with the improvement of living standard, people pursue living quality increasingly, cream paper appears, has the functions of moisturizing, smoothing and the like, and can protect skin to a certain degree. By adding the moisturizing component on the paper, the softness of the paper is well improved, the smoothness of the paper is greatly improved, the paper has silk-like touch, and the household paper is called as the cream paper. In the production process of the cream paper, the paper making production is completed according to the paper making mode of the household paper, and then cream substances are added on the paper for soaking.

The paper making process of the household paper generally comprises the steps of raw material selection → fiber separation by cooking → washing → bleaching → washing screening → concentration or pulp making piece making → storage for standby application, wherein in the bleaching step, the natural color paper pulp is bleached by a bleaching agent, colored substances in the paper pulp are removed to improve whiteness, the process usually needs to bleach the paper pulp by a special bleaching device, and a traditionally used paper pulp bleaching tower directly adopts a paper pulp input port and a bleaching agent input port, and two pipelines are mixed with each other to obtain bleached pulp. During the bleaching process of paper pulp, paper pulp with too high concentration is easy to be uneven with bleaching agent, so that the bleaching effect is poor and the bleaching efficiency is reduced.
