Process for replacing with fiber Wuben wood residue pulp in papermaking

Abstract

The invention relates to a process for replacing with fiber Wuben wood residue pulp in papermaking, which comprises the following steps of: feeding Wuben wood residue pulp raw materials into a hydrapulper through a chain plate machine to be pulped, and feeding the pulped Wuben wood residue pulp raw materials into an unloading pool after being defibered by a defibering machine; reasonably blendingraw wood pulp, Wuben wood residue pulp, American waste long fiber pulp, American waste short fiber pulp, national waste long fiber pulp and national waste short fiber pulp according to a certain proportion, and feeding the mixture into surface, core and bottom pulp blending pools for uniform mixing; and (3) respectively transferring the prepared pulp of the surface, core and bottom pulp blending pools into surface, core and bottom paper machine pulp forming pools through pipelines, and enabling the paper pulp in the surface, core and bottom paper machine pulp forming pools to pass through a net part, a pressing part and a front drying part, be subjected to sizing starch process treatment, pass through a rear drying part and a calendering machine, and be subjected to reeling and finished product packaging. According to the invention, under the condition of replacing part of raw wood pulp and American waste pulp with the Wuben wood residue pulp, the use amounts of a dry strength agent, areinforcing agent and sizing starch are optimized and adjusted, the overall pulp cost is effectively reduced, and waste is turned into wealth; and the use amount of American waste pulp is small, andthe dependence on American waste pulp is reduced.

Description

technical field [0001] The invention relates to a papermaking process, in particular to a papermaking process for replacing fiber uben wood pulp. Background technique [0002] Generally, raw wood pulp and waste wood pulp are used as raw materials. Among them, raw wood pulp has better burst resistance and performance, but the cost is higher, the consumption of forests, water and electricity is greater, and more pollutants are discharged. . From the perspective of sustainable development, the trend in the industry is to reduce the use of virgin wood pulp as much as possible, save living resources, and recycle renewable resources as much as possible. Waste paper wood pulp is a very important renewable material. Its papermaking production cost is relatively low, but there is still a problem of insufficient production capacity. Contents of the invention [0003] Therefore, aiming at the deficiencies in the prior art, the object of the present invention is to provide a novel p...
