Papermaking chemical mechanical pulp presoak softener and preparation method thereof

Abstract

The invention relates to a papermaking chemical mechanical pulp presoak softener and a preparation method thereof. The papermaking chemical mechanical pulp presoak softener is prepared from the following raw materials in percent by weight: 5-9% of alkyl sodium sulfonate, 10-16% of fatty alcohol-polyoxyethylene ether (2 ether-5 ether), 6-10% of alkyl phosphate, 1-4% of 98wt% concentrated sulfuric acid, 1-4% of anhydrous sodium sulfate and the balance of water. The invention also comprises the preparation method of the papermaking chemical mechanical pulp presoak softener; when being used for pulping, the papermaking chemical mechanical pulp presoak softener can reduce the power consumption by more than 2.3%, shorten the treatment time, improve the equipment efficiency and improve the productivity by more than 9%; and the yield of pulping can be improved by more than 2%.

Description

technical field [0001] The invention relates to an auxiliary agent used in the papermaking industry and a preparation method thereof, in particular to a papermaking chemical mechanical pulp presoaking softener and a preparation method thereof. Background technique [0002] At present, the production of chemical mechanical pulp in domestic papermaking is to chemically treat the raw materials and then carry out mechanical grinding. This pulping process has high energy consumption, heavy equipment load, frequent operation and maintenance, low production capacity and unsatisfactory product strength. In order to reduce energy consumption, reduce equipment load, reduce equipment maintenance workload, increase production capacity and product strength, in the pulping process, a few manufacturers have tried common penetrants, such as Shandong Sun Paper Co., Ltd. tried Amazon’s penetrant , but it didn't perform well and has been disabled. Facts show that the existing pulping process...
