Cement grinding aid (liquid)

Product introduction

Cement grinding aid is a chemical additive that improves the effect and performance of cement grinding. Its components often include liquid grinding aid mother liquor, triethanolamine, polymerized polyol, polymerized alcohol amine, triisopropanolamine, and ethylene glycol. , propylene glycol, glycerol, sodium fatty acid, calcium chloride, sodium chloride, sodium acetate, aluminum sulfate, calcium formate, calcium lignin, sodium lignin, etc.

Features

It can significantly increase the hourly output of cement, the strength of cement at each age, and improve its fluidity;

It can greatly reduce the phenomenon of electrostatic adsorption and encapsulation formed during the grinding process, and can also reduce the tendency of ultrafine particles formed during the grinding process to coalesce again;

Significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder separator, thereby reducing grinding energy consumption;

Cement produced using grinding aids has a lower compaction and agglomeration tendency, which is beneficial to cement loading and unloading and can reduce wall hanging in the cement warehouse;

Improve the distribution of cement particles and stimulate hydration dynamics, thereby increasing the early strength and later strength of cement.

Technical performance and recommended dosage

The technical performance meets the GB/T26748-2011》 National standards; the chloride ion content in cement shall not exceed 0.06%.

The recommended dosage should not exceed 3% of the cement dosage. [Note: The specific dosage should be determined according to the actual requirements of the project. 】

How to use and precautions

Before using grinding aids. Verify whether auxiliary equipment such as elevators and powder separators have a surplus capacity of about 30%;

The flow rate of grinding aid must be checked frequently to ensure that the amount is accurate;

During the washing, grinding and use process, if the product fineness and the grinding fineness (in closed-circuit grinding) become coarser, the amount of grinding aid should be appropriately reduced. Sometimes it is necessary to adjust by reducing the output during use;

Avoid drastically adjusting the amount of grinding aids and increasing production. Gradual adjustments should be made during stable production to avoid damaging the grinding condition.

Scope of application

Suitable for cement grinding process.
