example 1

[0021] First add 460Kg of water to the reaction tank, heat it to 45°C, add 60Kg of calcium lignosulfonate, and turn on the stirring blade at the same time, add while stirring, after the calcium lignosulfonate is completely dissolved, add 60Kg of ethylene glycol and 80Kg of silicic acid Sodium, stir for about 30 minutes; then add 200Kg triethanolamine and 60Kg triisopropanolamine while stirring, and stir for 30 minutes; finally add 80Kg molasses while stirring; The magnetic field of 7000 Gauss is used for magnetization treatment, stirring for 3 hours while magnetizing, filtering to remove the precipitate, and the clear liquid is filtered with a 325-mesh sieve to obtain the finished product.

[0022] The above-mentioned finished product was placed for 2 years without any precipitation.

example 2

[0024] First add 520Kg of water to the reaction tank, heat it to 45°C, add 80Kg of calcium lignosulfonate, and turn on the stirring blade at the same time, add while stirring, after the calcium lignosulfonate is completely dissolved, add 80Kg of ethylene glycol and 60Kg of silicic acid Sodium, stir for about 30 minutes; then add 120Kg triethanolamine and 80Kg triisopropanolamine while stirring, and stir for 30 minutes; finally add 60Kg molasses while stirring; The magnetic field of 6000 gauss is used for magnetization treatment, stirring for 3 hours while magnetizing, filtering to remove the precipitate, and the clear liquid is filtered with a 325-mesh sieve to obtain the finished product.

[0025] The above-mentioned finished product was placed for 2 years without any precipitation.

Abstract

The invention belongs to the technical field of cement technology admixtures, and relates to a composite high-efficient liquid cement grinding aid which contains water solution with the following materials by weight percent: 10 to 20 percent of triethanolamine, 5 to 10 percent of glycol, 5 to 10 percent of tri-isopropanolamine, 5 to 10 percent of calcium lignosulphonate, 5 to 10 percent of molasses, and 5 to 10 percent of sodium silicate; and the water solution is subjected to magnetization treatment. The composite high-efficient liquid cement grinding aid has the following advantages: by the magnetization treatment, solid / liquid stable suspension durability is good, no separation or sediment phenomenon occurs after long-term storage, dosing amount is low, application range is wide, hourly output of a cement grinding mill can be improved by 15 to 20 percent, cement strength can be improved by 1 to 2MPa, 5 to 8 percent of clinker can be saved, and 5 to 8 percent of industrial residue can be additionally dosed.

Description

technical field [0001] The invention relates to a composite high-efficiency liquid cement grinding aid, which belongs to the technical field of cement process admixtures. A small amount of grinding aid is added in the grinding process of cement production, which can improve grinding efficiency and cement performance. Background technique [0002] At present, the liquid cement grinding aids commonly used in the cement production industry mainly have deficiencies and unscientific aspects in the following technical aspects: such as long-term storage to produce precipitation, poor persistence of solid-liquid stable suspension, poor grinding aid effect, and narrow application range. The effect of improving cement performance is poor, containing NH 3 and other harmful ingredients, the use cost is high. Contents of the invention [0003] In order to overcome the deficiencies in the above technical aspects, the present invention provides a high-efficiency composite liquid cement ...
