Paper-making grade pulp bleaching plate modifying production technique

Abstract

The invention provides a denaturizing production technique of paper making bleaching wood pulp plate, which solves the problems of uneven dipping, slow hemicelluloses stripping, difficult accumulation descending, uneven cooking, single cooking method, single bleaching method and violent conditions existing in denaturizing production technique of wood pulp in the prior art. The invention comprises the following steps: wood pulp plate paging, alkali soaking, pressing, untwining and dispersion, cooking, washing, impurity removal, bleaching, a secondary washing and pulping; wherein, the wood pulp plate paging, alkali soaking, pressing, untwining and dispersion are to send papers into a alkali dipping barrel with concentration of 8 percent to 18 percent after the paper making bleaching wood pulp plates are separated by a paging device. When the wood pulp plates are changed into pulp with concentration of 3 percent to 7 percent, the pulp with concentration of 3 percent to 7 percent is sent to a squeezer to be squeezed and untwine and disperse fiber. By adopting the invention, the quality of the dissolved viscose fiber wood pulp can be better and more stable; furthermore, the invention provides wider selection range of raw material.

AI Technical Summary

Benefits of technology

This patented technology improves on traditional processes such as papermaking and making high strength fibreboard. It involves adding special chemicals called waterproof cellulosome pitch instead of chaffyrosine to improve wetting properties while maintaining good bond between different materials like glue and cobweb threads. By doing this, these products have improved performance compared to regular wooden pulps but they also require less energy than normal ones due to their lower melting point. Additionally, there's another advantage - burning them down after leaving residual ash behind when cleanliness ends up being contaminated. Finally, the resulting product has higher stability over longer periods of storage at room temperatures.

Problems solved by technology

The technical problem addressed in this patents relates to improves the efficiency and effectiveness of producing highly purified or delicate greenish type timber without causing issues like decomposition reactions and damaged filaments after extraction. Existing methods involve acid etchings followed by alkaline immersion treatment, evaporation drying, solvent exchange, centrifugal separation, heat transferring, etc., leading to inconsistencies between batch quality control data points and product properties.
