Triisopropanolamine (TIPA)is a surface active material that can greatly reduce the surface tension of water. When the cement is stirred with an aqueous solution doped with a trace amount of triisopropanolamine (TIPA), the surface tension of the solution is changed. The effect of the solution on the emulsification, wetting, permeation, adsorption and dispersion of the cement particles is remarkably enhanced, and it is easier to expand and adsorb on the surface and inside of the cement particles, so that the deep layer of the cement continues to be hydrated. Triisopropanolamine (TIPA) has a strong polarity due to its spatial three-dimensional molecular structure. It can play a good role in dispersing particles during cement grinding, so that cement particles do not agglomerate and form a larger ratio. Surface area, thus achieving a grinding effect.
In the cement production process, the grinding process of cement is a high energy consumption link. Due to the increasing shortage of active mixed materials such as fly ash and slag and the increase in cost, limestone powder has been used as a cement and concrete admixture in recent years. . Reasonable use of limestone powder can achieve better economic, technical and environmental benefits. When the cement reaches a certain fineness, there will be agglomeration between the particles, causing the paste ball and the adhesive liner to reduce the grinding efficiency. The addition of triisopropanolamine(TIPA) can improve this condition, improve grinding efficiency and increase productivity, and also improve cement particle diameter distribution, increase the compressive strength of cement, and reduce the energy consumption and energy reduction of the grinding process. Waste. In addition, since triisopropanolamine (TIPA) generally has an enhanced effect, the amount of cement clinker can be reduced, and the amount of mixed materials can be increased, thereby reducing coal consumption and reducing dust and gas pollutant emissions in clinker production. . Relative to the new dry process cement production process, the use of cement grinding aids has lower cost, and at the same time has better energy saving and emission reduction and improving cement quality.
