In cement concrete applications, triisopropanolamine has the following advantages in terms of dispersibility, age enhancement, and application conditions compared with triethanolamine: 1 Dispersibility is better, when used in cement grinding aids, The fundamental principle of the action of the grinding aid is the dispersibility of the two surfactants. The dispersibility of the triisopropanolamine is better due to the spatial stereostructure of the alkyl chain and the hydroxyl group of the triisopropanolamine. Triethanolamine; and dispersibility is an important indicator of cement. In practical applications, triisopropanolamine is superior to triethanolamine in improving the cement, and the fluidity of cement is better than that of triethanolamine.

SO 3 content helps to improve the early strength of triisopropanolamine cementree of hydration

In the cement industry production, in order to improve the grinding efficiency, reduce the power consumption of the mill, reduce the fineness of the cement, and improve the quality of the cement, a small amount of material-grinding aid must be added during the grinding process. The grinding aid is composed of one or more surface active substances and other chemical additives. It can reduce the surface energy of the grinding powder during the grinding process, overcome the attraction between the grinding powder, reduce the crushing resistance and prevent Paste the ball. Improve the fluidity of the mill, thereby reducing the power consumption of the mill and improving the grinding efficiency.

Triethanolamine and triisopropanolamine on slag cement impact of hydration process The slag cement has the advantages of low hydration heat, high late strength, inhibition of alkali aggregate reaction, and resistance to sulfate corrosion, and has been applied in a large number of projects. When producing slag cement, because the slag is more greasy than the clinker, the best active particle size can not be achieved when co-grinding, and the single grinding will cause a lot of energy consumption, so it is used in the grinding process. Grinding aids to reduce grinding energy consumption and improve cement performance. Triethanolamine (TEA) and Triisopropanolamine (TIPA) are the main components of common grinding aids.

Physical characteristics of triethanolamine and detailed application in different industry sectors Triethanolamine is a colorless to pale yellow transparent viscous liquid with a slight ammonia odor and a colorless to pale yellow cubic crystal at low temperatures. The color gradually darkens when exposed to the air. Soluble in water, ethanol, acetone, glycerin and ethylene glycol, etc., slightly soluble in benzene, ether and carbon tetrachloride, and almost insoluble in non-polar solvents. Irritating. It is hygroscopic. It can absorb acid gases such as carbon dioxide and hydrogen sulfide. Pure triethanolamine has no effect on steel, niobium, nickel and other materials, but is highly corrosive to copper, aluminum and its alloys. Unlike monoethanolamine and diethanolamine, triethanolamine and iodohydrous acid can form iodide precipitates. Combustible. Low toxicity. Avoid contact with oxidants and acids.
