Triisopropanolamine (TIPA) is a tertiary alkanolamine used as a grinding aid in cement production. It helps reduce agglomeration during the ball milling process by adsorbing onto cement particles, reducing surface energy, and preventing particle clumping. This results in a finer, more uniform particle size distribution, which improves the quality and performance of the cement.
TIPA also enhances milling efficiency by reducing friction between particles, lowering energy consumption and operational costs. It is highly soluble in water and alcohol, making it easy to integrate into the grinding process, ultimately contributing to higher-quality cement with better workability and durability.
