Application of Protein Purifying Agent on Solving Pollution of Surface Sizing Measuring Rod
This paper introduces the application of protein purifying agent to the surface sizing of large high-speed paper machine to solve the problem of measuring rod pollution.The practice shows that when the ratio of protein purifying agent to absolute dry starch is 10％,the problem of sizing measuring rod pollution is obviously improved,the rod replace period is prolonged from 0.5 day to 12 days,and the missed coating of sizing roller can not be seen.The origin and purity of the carrier used for protein purifying agent have a certain influence on the surface strength of paper,and the optimal origin and purity of the carrier are ascertained.After adding the protein purifying agent,the cost of sizing was reduced by 7 yuan,and the paper breaks and defects related to sizing glue were reduced obviously.
