Abstract

The invention discloses high-strength corrugated paper produced by using a bleaching technology and belongs to the technical field of paper making. The high-strength corrugated paper is prepared by the steps of secondary pretreatment, washing, pulping, bleaching, pressure filtration, beating, forming and the like. Unscreened yield, breaking length and a ring crush index of a process for preparingsugarcane bleaching pulp and the high-strength corrugated paper are remarkably higher than those of the prior art; the process accords with an industrial policy of resource conservation and circular economy in China; abundant and wasted material resources, such as bagasse, are developed and utilized, so that pollution is reduced, and economic benefits are increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high-strength corrugated paper produced by a bleaching process. 【Background technique】 [0002] The current pulp production methods mainly include chemical, semi-chemical, mechanical and chemical-mechanical processes. Among them, chemical pulping occupies a dominant position among many pulping methods at present. The pulp prepared by chemical cooking is called bleached sugarcane pulp. The low brightness of bleached sugarcane pulp limits its application. Bleached sugarcane pulp generally needs to be bleached to produce higher-grade paper. [0003] With the continuous expansion of the paper industry and the continuous expansion of the application of pulp, the supply of wood, which was originally the main raw material for papermaking, is gradually in short supply, resulting in excessive deforestation and affecting the ecological environment. Therefore, it is nec...
