AI Technical Summary

Problems solved by technology

The defect of this product is: anthraquinone is insoluble in water and lye, and surfactant is prone to produce a lot of foam
As a result, it is difficult to mix the product evenly in the lye during use, and it is easy to precipitate in the lye, resulting in unstable process, poor slurry uniformity, and relatively large foam. A large amount of foam accumulates in the working environment, making it difficult to operate

Abstract

The present invention provides a paper making adjuvant combination, its component and the weight percent are: the tetrahydrochysene anthraquinone 50-70%; fatty alcohol polyoxyethylene (9) ether 5-10%; dodecane alkyl sodium benzene sulfonate 10-30%;organic silicon defoamer1-10%. The products are used in paper industry, the adjuvant has the performance of mixing with alkaline solution evenly, the boiling time is shorted than traditional adjuvant and the products ratio is higher, the uniformity of pulp is better, and the production process has less foam, the operation is convenient and the working environment do not produce large foam.

Description

Technical field [0001] The invention relates to a paper-making auxiliary agent used in the papermaking industry, especially an auxiliary agent used in the cooking and pulping process. Background technique [0002] Usually commercially available cooking aids used in the paper industry are compounds of anthraquinone and surfactants. Its principle of action is to use anthraquinone to remove lignin and protect fibers; Anthraquinone and lye penetrate into the interior of the raw material. The defect of this product is: anthraquinone is insoluble in water and lye, and surfactant is easy to produce a lot of foam. The product is difficult to mix evenly in the lye during use, and it is easy to produce precipitation in the lye, resulting in unstable process, poor slurry uniformity, and relatively large foam. A large amount of foam is accumulated in the working environment, which is difficult to operate. With the development of the paper industry, there is an urgent need for a cookin...
