Dust-preventing tension-increasing additive for wet part

Abstract

The invention discloses a dust-proof tensile wet end additive, which contains the following components: polyvinyl alcohol 4-6, trisodium phosphate 6-9, sodium metasilicate 4-6, modified starch 20-25, dextrin 5- 7. Yuanming powder 16-22, aluminum sulfate 3-4, acrylate 5-7, carboxymethyl cellulose sodium 6-8, rosin gum 4-6, this additive can increase the fiber recovery rate by 20-36%, improve Paper tension 16-25%, reduce cost 22-32%.

Description

technical field

[0001] The invention relates to an additive for papermaking, in particular to a dustproof tensile wet end additive. technical background

[0002] As we all know, in the papermaking process, the recovery rate of pulp is a crucial issue, especially in the recycling process of waste paper, the proportion of short fibers is relatively high, and in the process of cooking and pulping, the loss of paper fibers is large, which is harmful to the environment. Large, low paper output, and high proportion of short fibers will easily reduce the quality of paper, flying fine paper fibers, low tensile strength, low economic benefits, so far, there is no good solution. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a paper-making dust-proof tensile strength that can improve the recovery rate of paper fibers, increase the tensile strength, smoothness and softness of paper, reduce the flyin...
