Application of diethanol monoisopropanolamine.
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. It can be used alone or in combination with other substances when making grinding aids. According to the characteristics of different cement materials, diethanol monoisopropanolamine as the core material, after targeted compatibility, has significant improvement on the early and late strength of cement. The grinding aid produced can increase the strength of the cement for 28 days while improving the strength of the cement for three days. In actual use, in the case of strong adaptability, the early strength can be raised higher than triethanolamine, but in general, the early strength is slightly lower than that of triethanolamine. It is certain that the late strength can be greatly improved, generally higher than triisopropanolamine.
