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

The invention relates to an active pulping agent for papermaking and belongs to the technical field of papermaking. The pulping agent is composed of an active agent, a main agent and an auxiliary agent, wherein the active agent is composed of: secondary octanol polyoxyethylene ether, oxidized polyethylene emulsion, ethanol, sodium dodecylbenzenesulfonate, sodium percarbonate , alkaline protease and talcum powder; the ingredients of the main agent are: calcium hydroxide, anthraquinone, sodium percarbonate, sodium dodecylbenzenesulfonate, anhydrous sodium sulfite and talc powder; the ingredients of the auxiliary agent are: alkaline protease , sodium percarbonate and talcum powder; mix active agent, main agent and auxiliary agent with each other, and stir evenly. The active pulping agent for papermaking of the present invention can be used for papermaking without using alkali and washing with a large amount of water, avoiding the discharge of sewage and greatly saving water. Compared with the strong alkali method, its pulp yield can be increased by 20%. The amount of chemical raw materials used is much less than that of the traditional papermaking process, which makes the pulp easy to bleach, consumes less water, contains less pollutants, and makes the middle water in the papermaking process easy to treat.

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] The 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 fibers into pulp to achieve papermaking. paper requirements. However, the strong alkali used in the traditional process destroys the short fibers, thus reducing the pulp yield and causing serious environmental pollution. This has caused serious problems in the paper industry. On the land of China, there is even no water and no pollution, no rivers and no pollution, which has directly endangered the living environment of human beings. 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 ...
