Embodiment Construction

[0008] The use mechanism and implementation mode of the present invention will be further described below. The present invention is phthalate production waste liquid, triethanolamine, benzene gangue, maleic gangue, sodium hydroxide, urea, wood calcium, molasses, polycarboxylate, sodium carboxymethyl cellulose, sodium benzoate, sodium formate And other chemical materials are compounded and prepared according to a certain strict ratio and a certain preparation process. When in use, the multi-multifunctional liquid cement grinding aid enhancer of the present invention is added to the feeding end of cement grinding with different mixing materials and different dosages through a speed-regulating metering pump at a different ratio of 1‰-3‰. After grinding, it is ground together with various materials required for the production of cement, which can prevent the adsorption, accumulation, shelling and pasting of various materials, improve the grinding efficiency, optimize the particle ...

Abstract

The invention provides a multi-element multifunctional liquid cement grinding aid reinforcing agent which adds 0.1-0.3% in the cement powder milling process and is prepared by combining phthalate production waste liquid, triethavolamine, anhydride, maleic anhydride, sodium hydroxide, urea, wood calcium, molasses, polycarboxylate, sodium carboxymethylcellulose, sodium benzoate, sodium formate, and the like. The invention improves the grinding efficiency and the cement fineness, optimizes the grain composition and the grain shape, has the functions of enhancing the tightness and improving the comprehensive performance of the cement concrete, and has the advantages of low cost, chlorine and harmfulness free, accurate measurement, convenient use, and remarkable grinding aid and enhancing functions. The invention is widely suitable for production of six common portland cements and other special cements, and can increase or decrease the formulation proportion in the invention according to the requirement.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a multi-functional and multifunctional liquid cement grinding aid of basic material chemistry. Background technique [0002] The liquid grinding aids used in the traditional cement production process are the aqueous solutions of alcohol amines, saturated fatty acids and sodium salts, potassium salts, salt water solution complex alcohol amines, calcium lignosulfonate, etc., such Grinding aid enhancer is used in cement production with high clinker and low mixed material content, and can play a certain role in increasing production and saving energy. With the rise of energy and raw material prices, the production of green and environmentally friendly high-performance cement with low clinker and high mixed materials has become the development direction of a new industrial revolution in cement production. The traditional liquid grinding aid enhancer consumes a l...
