Abstract
The invention relates to the technical field of grinding aids, in particular to a cement grinding aid. The cement grinding aid includes the following components: 40-52wt% of an aliphatic water reducer, 37-46wt% of calcium lignosulfonate, 2-7wt% of sodium hexametaphosphate, 7-15wt% of sodium carbonate and 2-8wt% of water glass. Preferably, the cement grinding agent comprises: 45wt% of the aliphatic water reducer, 40wt% of calcium lignosulfonate, 5wt% of sodium hexametaphosphate, 10wt% of sodium carbonate and 5wt% of water glass. By adding 0.05%-0.5% of the cement grinding aid provided by the invention, the mill output can be increased by 10%-50%, the power consumption of grinding can be reduced, the cement strength can be reinforced by 20%-80%, the fineness is significantly improved, and the cement, liquidity and workability are enhance.
Description
Technical field
The present invention relates to grinding aid technical field, particularly to a kind of cement grinding aid.
Background technology
In cement production process, the energy of powder-grinding process power consumption is the highest, and the utilization rate of energy is extremely low, causes annual manufacture of cement
Power consumption is very big, and in modern cement industry, cement grinding aid has become as in manufacture of cement and improves mill efficiency, reduction grinding electricity
One of consumption, the effective measures improving cement performance, reduction production cost.Along with developing rapidly of China's cement industry, energy-conservation subtract
The pressure of row is increasing, and cement production enterprise will increasingly pay attention to the application of grinding aid.
Existing cement grinding aid, for improving the mobility less effective of finished cement, reduces material and continues through the speed of grinding machine,
Being difficulty with the target of ball grinder saving energy high yield, capacity usage ratio is low, and the intensity of cement improves inconspicuous.
Summary of the invention
In order to solve problem of the prior art, the invention provides a kind of cement that can be effectively improved cement fluidity and intensity
Agent.
Technical scheme of the present invention is as follows:
A kind of cement grinding aid, including aliphatic water reducing agent, calcium lignosulfonate, sodium hexameta phosphate, dietary alkali and waterglass, respectively
Constituent content is as follows: aliphatic water reducing agent 40-52wt%, calcium lignosulfonate 37-46wt%, sodium hexameta phosphate 2-7wt%, alkali
Face 7-15wt% and waterglass 2-8wt%.
Preferably, each constituent content of cement grinding aid is as follows: aliphatic water reducing agent 45wt%, calcium lignosulfonate 40wt%,
Sodium hexameta phosphate 5wt%, dietary alkali 10wt% and waterglass 5wt%.
The technical scheme that the present invention provides has the benefit that
During wet grinding, by volume 0.05%-0.5% cement grinding aid of the present invention, the yield of grinding machine can be improved
10%--50%, reduces grinding pow consumption and other losses, and intensity enhancing 20%--80% of cement, fineness significantly improves, and enhances
Cement fluidity, workability.
