Problems solved by technology

However, the deinking effect of the deinking agent with biological enzymes as the main component is not very ideal. For example, the invention patent with the publication number of CN 101718000 A discloses "biological enzyme deinking process for waste newsprint". In this technical scheme, only cellulose is used. One or more of enzymes, xylanase, amylase or pectinase is used as the main component of the deinking agent. Although it is environmentally friendly, the deinking effect is not very ideal

Abstract

The invention discloses a biological deinking agent. The biological deinking agent is prepared from, by weight, 8-25 parts of biomass raw materials, 2,000-150,000 U / g of biological enzymes, 15-40 parts of surface active agent, 1-5 parts of acid or alkali and 5-20 parts of inorganic salt electrolyte. The biological deinking agent is mainly formed by mixing the biomass raw materials, the biological enzymes and the surface active agent, a biological matrix is mainly adopted in the obtained biological deinking agent, the quantity of adopted chemical additives is small, the biological deinking agent is degradable, environmentally friendly and good in deinking effect, and the whiteness of paper obtained after deinking of the deinking agent is high.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a biological deinking agent. Background technique [0002] The deinking agents currently used in the market are mainly flotation deinking agents and washing deinking agents. Flotation deinking agent is the most widely used and most effective deinking agent in waste paper deinking production. Flotation deinking agents mainly include anionic fatty acid soap (sodium soap), nonionic fatty alcohols and fatty ethers, complex surfactants, biological enzymes, etc., of which anionic fatty acid soap (sodium soap) and surface active Compound deinking agents have always been the two most important deinking agents used in domestic and foreign markets. [0003] In the waste paper recycling, the deinking agent is mainly used to destroy the adhesion of the ink to the fiber, so that the ink is peeled off from the fiber and dispersed in water. Traditional chemical deinking agents contain al...
