Embodiment Construction

[0007] The first embodiment of the present invention. The white cement grinding aid consists of 5% wollastonite powder with an average particle size of 2.58 microns, 28% triethanolamine, 49% ethylene glycol and 18% sodium oleate. When preparing, first put 5% wollastonite powder into 49% ethylene glycol, stir for half an hour to obtain the mixture; then, heat the mixture to 40 degrees Celsius, put 18% sodium oleate into the mixture and stir for 20 minutes; finally add 28% triethanolamine, stir well to get white cement grinding aid.

[0008] The second embodiment of the present invention. The white cement grinding aid consists of 30% wollastonite powder with an average particle size of 2.58 microns, 21% triethanolamine, 40% ethylene glycol and 9% sodium oleate. When preparing, first put 30% wollastonite powder into 40% ethylene glycol, stir for half an hour to obtain the mixture; then, heat the mixture to 50 degrees Celsius, put 9% sodium oleate into the mixture and stir for 2...

Abstract

The invention discloses a white cement grinding aid. The white cement grinding aid comprises, by mass percentage, 5-30% of wollastonite powder, 21-30% of triethanolamine, 40-50% of ethylene glycol and6-20% of sodium oleate. The white cement grinding aid can increase white cement raw material grinding efficiency and lower energy consumption and can also effectively lower clinker fine powder surface energy, avoid particle aggregation and improve clinker fine powder fineness without affecting clinker whiteness.

Description

technical field [0001] The invention relates to cement grinding technology, in particular to a white cement grinding aid. Background technique [0002] As a process additive in the cement production process, cement grinding aids have the functions of saving energy, reducing consumption and improving cement quality. White Portland cement, referred to as white cement for short, is a portland cement clinker with calcium silicate as the main component and low iron oxide content obtained by burning raw materials with appropriate ingredients until it is partially melted. Adding an appropriate amount of gypsum meets the standards It is a white hydraulic cementitious material made of finely ground limestone and other mixed materials. The typical characteristics of white cement are high whiteness and bright color. It is generally used as a variety of building decoration materials, typically including stucco, sculpture, floor, terrazzo products, etc. White cement can also be used to...
