Haisen Chemical is one of the main manufacturer of TIPA （ Triisopropanolamine ）and DEIPA ( Diethanolisopropanolamine ) used in cement grinding aids. Along with concrete water reducing agent-Polycarboxylate Superplasticizer.

Alkanolamines are amines containing a single, double, or triple hydroxyalkyl group. They are frequently used as concrete admixtures and grinding aids. The action of triethanolamine (TEA) in the hydration of cement is not described explicitly in the literature since it has still not been concluded whether it is an accelerator or a retarder.

Diethanolisopropanolamine (DEIPA85%) has similar or comparable basic characteristics-dispersibility compared with triisopropanolamine and triethanolamine in cement and cement concrete additives, but its comprehensive performance has obvious advantages. According to the statistical results, under the same conditions, the early strength is higher or lower than that of triethanolamine, and the late strength is much higher than that of triethanolamine. The early strength is much higher than that of triisopropanolamine, and the later strength is lower than that of triisopropanolamine. Its specific characteristics are as follows:

Since the 1930s, cement grinding aids have been used in the cement industry. The earliest patents of the 1930s tested and used powdered mixtures of mineral oil, animal oil and petroleum cracking residues to improve the water resistance of cement products and improve the high early strength and processability of cement. It is combined with hydrochloric acid or calcium chloride, lime-type calcium-containing material and an inert adsorbent mineral material as a carrier. These admixtures greatly improve the water resistance of the cement series and improve its processability.

Introduction to the performance of cement grinding aids The so-called cement grinding aid is an admixture that aids in grinding in the cement grinding process to improve cement grinding and improve production efficiency without compromising cement performance. In order to improve the water resistance of the cement series, improve the early strength and the processability of the cement, the powder mixture of mineral oil, animal oil and petroleum cracking residue is tested and used, and combined with hydrochloric acid or calcium chloride, lime or calcium-containing substance. Minerals with inert and adsorptive properties are used as carriers. These admixtures greatly improve the water resistance and processability of the cement series.

Diethanol monoisopropanolamine was produced in the 1990s and is a non-toxic, skin-irritating product that is less irritating to triethanolamine and environmentally friendly alkanamines. It is mainly used as a surfactant. In the fields of cement grinding aids, daily chemical products and fabric softe
