Problems solved by technology

For this reason, the state closed tens of thousands of small and medium-sized paper mills, resulting in a large number of laid-off workers and no livelihood.
In order to maintain their survival, pulp and paper companies need to spend a lot of money on alkali recovery, but the cost is huge, which greatly increases the cost of paper

Abstract

This invention involves a papermaking active pulp making, belongs to the papermaking technology. It is composed by the active ingredient, the host medicinal preparation and the auxiliary medicinal. The active ingredient components is: propyl butyl-carbinol polyethyleneoxide ether, oxidized polyethylene emulsion, ethyl alcohol, lauryl benzene sulfonic acid sodium, sodium monoperoxy, alkalinity proteinase and talcum powder; The main medicinal preparation's components is: calcium hydroxide, anthraquinone, sodium monoperoxy, lauryl benzene sulfonic acid sodium, anhydrous sodium sulfite and talcum powder; The auxiliary medicinal preparation's ingredient is: alkalinity proteinase, sodium monoperoxy and talcum powder; Mix the active ingredient, the host medicinal preparation and the auxiliary medicinal preparation. This invention's papermaking active system paste, may not use the alkali, does not need the massive laundering, has avoided the sewage emissions, greatly economize on water. Its thick liquid rate compares with the strong alkali method, may enhance 20%. The use of industrial chemicals is greatly reduced, and so on.

Description

Technical field [0001] The invention relates to an active pulping agent for papermaking, and belongs to the technical field of papermaking. Background technique [0002] Traditional papermaking technology uses strong alkali to extract lignin and other impurities in plant fibers. The principle is peeling reaction, that is, strong alkali extracts lignin and other impurities in plant fibers to saponify the fiber into pulp to achieve papermaking. Paper requirements. However, the strong alkali used in the traditional process destroys short fibers, thereby reducing the yield of pulp and causing serious environmental pollution. This has caused serious problems in the paper industry, and even on the land of China, there is no water, no pollution, no river, no pollution, and it has directly endangered the living environment of mankind. For this reason, the state has closed tens of thousands of small and medium-sized paper mills, causing a large number of workers to be laid off and have no...
