Description

Bleaching and pulping device for producing certificate roll

Technical Field

The invention relates to the technical field of stock form paper, in particular to a bleaching and pulping device for stock form paper production.

Background

A security paper is one type of intaglio printing paper. Paper for printing banknotes, bonds and various documents. The paper is tough, wear-resistant and folding-resistant, and has high durability. The raw material is bleached chemical wood pulp or bleached new rag pulp, or part of cotton-flax pulp can be mixed, and the raw material is undergone the process of free-form beating by using long fibre, generally, it is not added with filler, and is made by using fourdrinier paper-making machine. Conventional pulping refers to a process of dissociating plant fiber raw materials into natural color or bleached pulp using chemical methods, mechanical methods, or a combination thereof.

The pulp bleaching tower used traditionally adopts a pulp input port and a bleaching agent input port directly, and two pipelines are mixed with each other to obtain bleached pulp. In this process, high pulp consistency helps reduce bleach liquor usage, but pulp with too high consistency tends to result in uneven mixing of the bleach with the pulp, reducing bleaching efficiency. In addition, some traditional making beating devices not thoroughly cause the jam of grout outlet because of the making beating, not only influence the processingquality of paper, still influence production efficiency.
