Product performance: Diethanol monoisopropanolamine (DEIPA) is mostly used in cement grinding aids to replace triethanolamine and triisopropanolamine in grinding aids, and has excellent grinding aid effect. The grinding aid made with diethanol monoisopropanolamine as the core raw material can improve the strength of cement for 28 days while improving the strength of cement for 3 days. In the case of strong adaptability, the early strength can be higher than that of triethanolamine, but in general, it is slightly lower than that of triethanolamine. Undoubtedly, the later strength can be greatly improved, generally higher than that of triisopropanolamine. high.

Application range: 1. Used as a cement grinding aid, it can improve the grinding efficiency, and has a significant effect on improving the strength of the cement after the mud; the recommended dosage range is 0.005~0.015%, and the actual dosage is suggested to be determined by the customer according to the specific situation. 2. This product can be used alone or in combination with triethanolamine, triisopropanolamine and other alcohols, amines and esters. 3. It is used as cement grinding aid to enhance 3~5MPa in the early stage and 4~8MPa in the later stage. 4. The molecular structure contains both alcohol and amine functional groups, which can react with various substances under appropriate conditions to form esters, amide salts, etc.

Packaging specification: 200kg iron drum, other specifications are customized according to user requirements.

Storage and transportation: sealed and transported to prevent collision, sunlight, rain, away from fire sources, and stored in a clean, dry and cool and ventilated place.

Product shelf life: Under the specified storage and transportation conditions, the shelf life is two years.
