CAS Number: 6712-98-7
Diethanolisopropanolamine is an aminoalcohol and belongs to the group of alkanolamines used in Cement grinding aid and Concrete strength enhance business. The product could effective increase cement grinding effect, used to replace triethanolamine and triisopropanolamine in new type amine cement grinding aid.
Features & Application:
Diethanolisopropanolamine as cement grinding aid could effective increase cement mill output, reduce cement mill powder consume, increase cement & concrete 3 days & 28 days strength.
Diethanolisopropanolamine can be used alone, and can with TEA,TIPA and other alcohols, amine ester used material compatibility.
The Triisopropanolamine,Diethanolisopropanolamine,Triethanolamine as cement grining aid could effective participate in hydration reaction with , C3A, C3S, C2S, and C4AF.
Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement grinding. It can significantly increase the output of cement platform, the strength of cement at various ages, and improve its fluidity. The cement grinding aid can greatly reduce the phenomenon of electrostatic adsorption ball formation formed during the grinding process, and can reduce the re-agglomeration tendency of the ultrafine particles formed during the grinding process. The cement grinding aid can also significantly improve the fluidity of the cement, improve the grinding effect of the mill and the powder selection efficiency of the classifier, thereby reducing the energy consumption of the grinding. The cement produced by the grinding aid has a lower tendency of compaction and coalescence, which is beneficial to the loading and unloading of the cement and can reduce the wall hanging phenomenon of the cement storage.
With the rapid development of China's cement industry, the pressure of energy saving and emission reduction is getting bigger and bigger, cement production enterprises will pay more and more attention to the application of grinding aids, and the application prospect of grinding aids will be very broad. The main raw material used by some foreign companies for grinding aids is de-sugar wood sulfonate.
The use of industrial by-products as cement grinding aids has a very broad application prospect. Some foreign scientists use natural bio-glycerol, a by-product of biodiesel manufacturing, to replace common cement grinding aids such as ethylene glycol and hydroxylamine for cement grinding process. Using cement from different regions of Belgium, Greece and Italy, it was found that this bio-glycerol blended with 5% NaCl was more effective than the high-purity grade glycerol. In addition, this bio-glycerol can significantly improve cement.
Founded in 1993, Shijiazhuang Haisen Chemical Co., Ltd. is located in Shijiazhuang, the capital of Hebei Province. After more than 20 years of development, it has developed into a combination of science, industry and trade, and the development and manufacture of specialized fine chemicals combined with domestic and foreign trade. enterprise. The products are sold to all provinces, autonomous regions and municipalities in China, and exported to more than 30 countries and regions such as Russia, Turkey, France, Iran and Vietnam.
The development status of DEIPA in China and its future development prospects and application in cement grinding aids
China's DEIPA is mainly used in cement grinding aids. The dosage is 0.5 to 10,000 parts per million of cement. It can be combined with polyol, triethanolamine and harmless inorganic salts. It can be designed as a high-volume product. It can be used to enhance multi-mixed materials. It can also be designed as a low-volume product for high-grade cement to achieve a comprehensive effect of enhanced production
Diethanol monoisopropanolamine is mostly used in cement grinding aids to replace triethanolamine and triisopropanolamine in the grinding aid raw materials. Diethanol monoisopropanolamine is a new environmentally friendly grinding aid material with excellent grinding effect.
Use of diethanol monoisopropanol in the cement chemical industry
Diethanol monoisopropanolamine is mostly used in cement grinding aids to replace triethanolamine and triisopropanolamine in the grinding aid raw materials. Diethanol monoisopropanolamine is a new environmentally friendly grinding aid material with excellent grinding effect. It has good compatibility with triethanolamine, triisopropanolamine and other alcohols, amines and lipids.
