Embodiment 1

[0023] In the process of producing corrugated base paper with imported American waste paper as raw material, add primary sludge with 0.5% pulp fiber mass; biochemical sludge with 1% pulp fiber mass; 1% pulp fiber mass in the mixed stock tank before the paper machine cationic starch; cationic polyacrylamide with pulp fiber quality 0.01%; mixed evenly; online papermaking, pre-drying, surface sizing with surface sizing starch, and post-drying; surface sizing starch is corn starch, and its dosage is primary precipitation 1 times the total amount of sludge and biochemical sludge. The primary sludge is the sludge produced in the primary sedimentation tank during the sewage treatment process, and the biochemical sludge is the system residual sludge settled in the secondary sedimentation tank and advanced treatment after aerobic treatment in the sewage treatment process. The main process conditions of corrugated base papermaking: the concentration of paper material on the net is 0.5wt...

Abstract

The invention discloses a corrugated medium produced from waste paper papermaking sludge as well as a production method of the corrugated medium. In the process for producing the corrugated medium from waste paper used as a raw material, primary sludge with the paper pulp fiber mass ranging from 0.5% to 2%, biochemical sludge with the paper pulp fiber mass ranging from 0.5% to 1%, cationic starch with the paper pulp fiber mass ranging from 0.1% to 1% and cationic polyacrylamide with the paper pulp fiber mass ranging from 0.01% to 0.08% are added to a paper-making machine pulp tank and evenly mixed, the corrugated medium is produced after net loading, paper-making with pulp, pre-drying, surface sizing with surface sizing starch and after-drying, and the consumption of the surface sizing starch is 0.2-1 time the total amount of the primary sludge and the biochemical sludge. The waste paper papermaking sludge is used for producing the corrugated medium, waste paper raw material consumption can be reduced, the production cost can be reduced, and the economic benefit is better; meanwhile, the yield of solid waste can be greatly decreased, the pollutant end treatment cost can be reduced, and the environmental benefit is significant.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of resources in the papermaking industry, in particular to a corrugated base paper produced by using waste paper and papermaking sludge and a production method thereof. Background technique [0002] With the continuous improvement of the level of economic development, the paper industry has developed rapidly. While bringing economic benefits, it has also caused environmental pollution problems. The water pollution of the paper industry ranks among the best in various industries; waste gas, solid waste and Noise and other pollution are also serious. [0003] During the production of packaging paper and cardboard from waste paper, waste water is produced, and waste water treatment produces sludge. Typical wastewater treatment processes include primary sedimentation and aerobic treatment, and primary sludge and secondary sludge will be produced during the production process. The a...
