Abstract
The adopted technical solution is that a kind of cement grinding aid for improving mill efficiency, main component is water and anhydrous calcium chloride, it is characterised in that：It is also added into sulfonated melamine resin 15-20 parts, modified polyurethane dispersant 5-15 parts, sodium pyrophosphate 15-20 parts, calcium lignosulfonate 5-10 part.Compared with prior art, the present invention had the advantage that for：The present invention is by adding sulfonated melamine resin, modified polyurethane dispersant, sodium pyrophosphate, calcium lignosulfonate so that the grinding aid has good effect.
Description
Technical field
A kind of the present invention relates to grinding aid technical field, more particularly to cement grinding aid for improving mill efficiency.
Background technology
Cement grinding aid is a kind of chemical admixture, and mixing in cement pulverizing course can improve grinding process on a small quantity.In order to improve mill efficiency, reduce grinding pow consumption, improve cement fineness and strength of cement, on the premise of factory's existing process and appointed condition is not changed, in grinding process, add the mechanical force that micro or a small amount of grinding aid goes to affect grinding operation.
Content of the invention
Technical problem to be solved is the defect for overcoming prior art to exist, there is provided a kind of cement grinding aid of raising mill efficiency.
The adopted technical solution is that a kind of cement grinding aid for improving mill efficiency, main component is water and anhydrous calcium chloride, it is characterised in that：It is also added into sulfonated melamine resin 15-20 parts, modified polyurethane dispersant 5-15 parts, sodium pyrophosphate 15-20 parts, calcium lignosulfonate 5-10 part.
Compared with prior art, the present invention had the advantage that for：The present invention is by adding sulfonated melamine resin, modified polyurethane dispersant, sodium pyrophosphate, calcium lignosulfonate so that the grinding aid has good effect.
