Abstract

The invention discloses a cement grinding aid. The cement grinding aid is prepared from the following ingredients in parts by weight: 10-15 parts of diacetal monoisopropanolamine, 3-5 parts of triethanolamine, 4-6 parts of sodium acetate, 6-10 parts of sodium thiosulfate, 10-12 parts of sodium chloride, 6-8 parts of hydroxyethyl cellulose and 15-18 parts of papermaking black liquor. The cement grinding aid disclosed by the invention is low in consumption, good in enhancement effect and low in cost.

Description

technical field [0001] The invention belongs to the technical field of cement production and processing, and in particular relates to a liquid cement grinding aid. Background technique [0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the output of cement table, the strength of cement of all ages, and improve its fluidity. Cement grinding aids can greatly reduce the phenomenon of electrostatic adsorption and ball formation during the grinding process, and can reduce the tendency of re-agglomeration of ultrafine particles formed during the grinding process. Cement grinding aids can also significantly improve the fluidity of cement, improve the grinding effect of the mill and the powder selection efficiency of the powder separator, thereby reducing the energy consumption of grinding. Cement produced with grinding aids has a lower tendency to compact and agglomerate, which facilitates ...
