Triisopropanolamine is prepared by reaction of pure ammonia with propylene oxide,it used as addictive cement clinker grinding process, significantly improve grinding effeciency and reduce energy consumption.
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.
The use of triisopropanolamine cement grinding aids has good grinding effect and significantly improves the strength of the later period of the cement. The raw material triisopropanolamine is based in China and reduces the cost of cement grinding, and has broad application prospects.
Triisopropanolamine - molasses as reinforcement cement grinding aid The grinding aid and reinforcing effect of triisopropanolamine (TIPA)- molasses compound grinding aid on cement were studied, and the grinding aid mechanism and reinforcement mechanism were discussed.
