Under the COVID-19 crisis tendency,most of trade company have not good earning in the field of foreign trade.But after the epidemic ,it will be springtime,the demend of DEIPA most from cement grinding agent. Increasing urbanization creats the needs for commercial,and residential buildings,the higher quality requirement for cement.And recent years the use as surfactant in DEIPA get more people,so we could see the wide trendence of DEIPA ,it is also have strong competitiveness in many coporations.
Diethanol-isopropanolamine (DEIPA) is a tertiary alkanolamine used in the formulation of cement grinding-aid additives and concrete early-strength agents. In this research, isothermal calorimetry was used to study the hydration kinetics of Portland cement with DEIPA.
1.It has good compatibility with triethanolamine, triisopropanolamine and other alcohols, amines and lipids, and can be used alone or in combination with other substances when making grinding aids.
2. Taking diethyl alcohol monoisopropanolamine as the core raw material, after targeted compatibility, the strength of cement in the early and late stages was significantly improved.
3.The grinding aids can improve the strength of cement for 28 days while improving the strength of cement for 3 days.Can greatly improve the late strength, generally higher than triisopropanolamine.
Store in clean,dry and ventilate place,aviod crash,sunshine and drench.
Sealed transportation,with 220kg/iron drum,also could do other size under the clients requirements.
Shelf life is two years general.
