BLIT Chemical supplies Diethanolisopropanolamine (DEIPA) CAS 6712-98-7 as a fine chemical additive mainly used as a raw material for cement grinding aid formulations. As a DEIPA supplier, BLIT Chemical provides Diethanolisopropanolamine with controlled quality specifications for cement additive manufacturers and cement production companies requiring stable performance and continuous supply.

Diethanolisopropanolamine (DEIPA) is an important alcohol amine compound synthesized from diethanolamine and propylene oxide. It is widely used as a new-generation cement grinding aid component and can be applied alone or combined with other additives such as triethanolamine (TEA), triisopropanolamine (TIPA), sodium gluconate, molasses, and lignosulfonate.

Compared with traditional alcohol amine additives, DEIPA is designed to provide balanced grinding efficiency improvement and cement strength enhancement. It can improve cement specific surface area, promote grinding efficiency, improve powder flowability, and support both early-age and later-age cement strength development under suitable formulation conditions.

BLIT Chemical produces DEIPA using advanced external circulation drop-feed reactors and fully automated DCS control systems. The production process provides advantages including high main content, good selectivity, low alcohol ether content, and light product color.

BLIT Chemical focuses on the research, production, and service of cement additives, concrete admixtures, and epoxy derivative fine chemicals. With integrated production capabilities from raw materials to finished products, BLIT Chemical supports customers with stable supply solutions for domestic and international markets.

DEIPA 85% Applications

Cement Grinding Aid Raw Material

Diethanolisopropanolamine (DEIPA) is mainly used as a raw material component for cement grinding aid production.

DEIPA-based grinding aid systems can help:

• Improve cement grinding efficiency
• Increase cement specific surface area
• Reduce grinding energy consumption
• Improve cement powder flowability
• Increase mill productivity under suitable production conditions

The actual performance depends on cement composition, grinding process, and formulation design.

Cement Strength Enhancement

DEIPA can contribute to both early-age and later-age cement strength performance.

Based on application conditions, DEIPA grinding aid systems may help improve:

• 3-day strength performance
• 28-day strength performance
• Cement particle distribution
• Utilization efficiency of supplementary materials

Application tests have shown that DEIPA-based formulations may contribute to:

• 3d strength improvement of approximately 3-5 MPa
• 28d strength improvement of approximately 4-8 MPa

The actual results depend on clinker composition, cement type, and additive formulation.

Application in Different Cement Types

DEIPA can be evaluated in:

• Portland cement
• Ordinary Portland cement
• Composite Portland cement
• Slag Portland cement
• Pozzolanic Portland cement
• Fly ash Portland cement
• High fineness slag powder

Grinding Aid Formulation Compatibility

DEIPA can be used independently or combined with other grinding aid components, including:

• Triethanolamine (TEA)
• Triisopropanolamine (TIPA)
• Sodium gluconate
• Molasses
• Lignosulfonate

Formulators can adjust the ratio according to cement performance requirements and production targets.

BLIT Chemical also supplies other alcohol amine products for cement grinding aid formulations, including Triisopropanolamine (TIPA) and Triethanolamine (TEA). Different alcohol amine materials can provide different performance characteristics in cement grinding systems. DEIPA is commonly selected when customers need balanced improvement in grinding efficiency, early-age strength, and later-age strength performance, while TIPA can provide strong dispersing and grinding aid effects in suitable cement formulations. Customers can select individual products or develop combined formulations according to clinker composition, supplementary materials, and production targets.

Usage Guidelines

Recommended Dosage

When used as an individual grinding aid component:

Recommended dosage: 0.005%-0.03% based on cement weight

When combined with other components, the dosage should be optimized according to application performance.

Addition Method

DEIPA can be added through:

• Cement mill feeding belt
• Pipeline addition to the front chamber of the grinding mill

Accurate measurement and uniform addition are important to maintain consistent grinding aid performance.

Factors Affecting Dosage Selection

The optimum DEIPA dosage depends on:

• Grinding efficiency target
• Clinker mineral composition
• C4AF content
• Supplementary materials type
• Fly ash content
• Slag powder content
• Limestone powder content
• Cement particle size distribution
• Specific surface area
• SO₃ content

Actual application dosage should be determined through laboratory and production trials.

Application Evaluation Before Bulk Production

BLIT Chemical recommends customers evaluate:

• Cement clinker characteristics
• Grinding equipment conditions
• Compatibility with other grinding aid components
• Target cement strength requirements
• Pilot grinding performance

This helps determine the suitable DEIPA dosage and formulation ratio.

Storage & Handling

Store Diethanolisopropanolamine in a cool and dry environment.

Recommended handling:

• Keep containers sealed
• Avoid contamination during transfer
• Use clean equipment
• Protect from extreme temperature conditions
• Follow MSDS handling requirements

Proper storage and handling help maintain product stability during transportation and application.

Packaging

Available packaging:

• 200kg drum
• 1000kg IBC

Container loading:

• 200kg drums: approximately 16MT / 20GP
• 1000kg IBC: approximately 20MT / 20GP

Samples are available for quality evaluation and formulation testing.
