Product Description

Description of DEIPA 85%

Diethanol Isopropanolamine (DEIPA) is an organic chemical compound widely used as a grinding aid and performance enhancer in cement and concrete applications. It belongs to the alkanolamine family and is particularly effective in improving the quality and efficiency of cement production. DEIPA is a colorless to pale yellow liquid with a mild amine odor and is commonly supplied in a concentration of 85% (DEIPA 85%) in water. Its primary role is to improve cement hydration, increase the strength of cement-based materials, and reduce energy consumption during grinding.

Key Features

1. Cement Grinding Aid:

   • Reduces clumping and agglomeration of cement particles during grinding, improving grinding efficiency.

2. Performance Enhancer:

   • Enhances early and late-stage cement strength by promoting hydration reactions in clinker and other cementitious materials.

3. Energy Efficiency:

   • Helps reduce energy consumption in cement grinding processes by improving mill throughput and reducing grinding resistance.

4. Water Solubility:

   • Fully soluble in water, making it easy to incorporate into liquid formulations.

5. Stability:

   • Chemically stable under typical storage and processing conditions.

6. Eco-Friendly:

   • DEIPA is considered less toxic and more environmentally friendly compared to traditional amines like triethanolamine (TEA).

 

Applications

1. Cement Grinding Aids:

   • Used as a primary raw material for grinding aids in cement production.
   • Reduces grinding energy consumption and enhances mill efficiency.

2. Cement Performance Enhancer:

   • Improves early compressive strength (1–3 days) and late compressive strength (7–28 days) of cement-based products.
   • Promotes better particle dispersion and hydration of clinker phases.

3. Blended Cements:

   • Particularly effective in formulations with supplementary cementitious materials like fly ash, slag, or pozzolans.

4. Concrete Admixtures:

   • Enhances the workability and strength of concrete by improving cement hydration in concrete formulations.

5. Specialty Cementitious Products:

   • Used in self-leveling compounds, dry mortar mixes, and other specialty products where improved strength and hydration are required.
