Applications:

Cement Grinding Aids: DEIPA 85% is used as cement grinding aid to enhance grinding efficiency, reduce clinker particle agglomeration, and improve cement flowability, resulting in higher throughput and lower energy costs.

Concrete Admixtures: Improves the workability and strength of concrete, making it ideal for high-performance concrete used in construction projects such as bridges, buildings, and infrastructure.

Chemical Intermediates: Serves as a versatile intermediate in the synthesis of surfactants, emulsifiers, and corrosion inhibitors for applications in coatings, lubricants, and agricultural chemicals.

Industrial Formulations: Acts as a neutralizing agent and stabilizer in specialty chemicals, enhancing product performance in industries such as textiles and metalworking fluids.

Technical Mechanism

DEIPA acts as a surface-active agent, reducing electrostatic attraction between cement particles during grinding. This leads to:

Better dispersion
Reduced coating effect
Increased mill output

Additionally, DEIPA promotes hydration reactions, improving C3A and C4AF phase activity, which directly enhances cement strength.

FAQ:

What is DEIPA 85% (Diethanol Isopropanolamine 85%)?

DEIPA 85% is an industrial-grade alkanolamine with a minimum active content of 85%, chemically named 2-(bis(2-hydroxyethyl)amino)-1-propanol (CAS No.: 6712-98-7). It appears as a colorless to pale yellow transparent liquid with a slight ammonia odor, featuring low toxicity and excellent compatibility with other chemicals.

Why choose DEIPA 85% over TEA or TIPA?

DEIPA 85% has better grinding aid performance, lower energy consumption (reducing cement grinding energy use), and stronger activation effect on supplementary cementitious materials (fly ash, slag). It also has lower toxicity, is more environmentally friendly, and supports low-carbon cement production.

How to store DEIPA 85% safely?

Store in a cool, dry, well-ventilated warehouse, away from direct sunlight and high temperatures. Keep in sealed, corrosion-resistant containers (plastic drums, IBC tanks, or ISO tanks) and keep away from children and incompatible substances (acids, oxidants).

Does DEIPA 85% affect the setting time of concrete?

No. It acts as a retarder and water reducer in concrete, prolonging the initial setting time to improve workability without compromising strength development. It also optimizes the microstructure of hardened cement paste.

How does DEIPA 85% improve cement grinding efficiency?

It reduces electrostatic adhesion and particle agglomeration during cement grinding, optimizes particle size distribution, improves material fluidity, and increases mill throughput by 10%-20% while reducing energy consumption.
