Powder grinding aid capable of improving cement performance

Abstract

The invention relates to a cement powder grinding aiding material, in particular to a powder grinding aid capable of improving the cement performance, belonging to the technical field of the cement power grinding. The powder grinding aid capable of improving the cement performance is prepared from the following raw materials by weight part: 1-3 parts of triethanolamine, 1-3 parts of triisopropanolamine, 10-15 parts of industrial salt, 15-35 parts of sodium sulphate, 5-15 parts of aluminum sulphate, 15-30 parts of gypsum, 1-5 parts of sodium tripolyphosphate, 1-5 parts of sodium hexametaphosphate and 10-30 parts of limestone powder. The powder grinding aid is formed by compounding common chemical raw materials and a mining waste. The raw materials of the powder grinding aid are readily available and have sufficient sources. The powder grinding aid has low toxicity and low cost, is non-volatile and is easy to process and prepare, and in addition, the powder grinding aid has stable performance and high performance-price ratio. All the indexes of the powder grinding aid meet the standard requirements of the cement grinding aid JC / T667-2004. Due to the adoption of the powder grinding aid, the power can be saved, the efficiency of grinding the cement into power can be effectively improved, and the quality and the performance of the cement can be effectively improved.

Description

technical field [0001] The invention relates to a powder cement grinding aid, in particular to a powder grinding aid for improving cement performance. The invention belongs to the technical field of cement grinding. Background technique [0002] When cement production enterprises produce cement, in order to solve the problems of high grinding power consumption, low grinding efficiency, improve cement strength and other physical properties, increase the amount of mixed materials, and reduce costs in the cement production process, they often add cement grinding aids. agent. Cement grinding aids can reduce the surface energy of the material during the grinding process, eliminate the static electricity between the material powder, and change the fluidity of the powder in the mill, thereby increasing the powder efficiency and improving the cement particle gradation. Grinding aids sold on the market today are generally divided into powder grinding aids and liquid grinding aids. ...

AI Technical Summary

Problems solved by technology

Although they all meet the standard of "Cement Grinding Aids", the effect is quite different due to the different components

The performance of the existing cement powder grinding aids is relatively single. They only focus on increasing the output of the mill, increasing the strength of the cement and changing some physical properties of the cement. They cannot comprehensively solve the problems in the cement production and cannot save more for the cement production enterprises. much cost

At the same time, the existing products cannot combine the effective grinding aid ingredients together, thus failing to exert the best effect of the cement grinding aid
