Description
Technical field
The present invention relates to field of cement production, especially a kind of cement grinding aid.
Background technology
Cement grinding aid is a kind of chemical addition agent improving cement grinding effect and performance, can significantly improve cement platform
Time yield, each age strength of cement, improve its mobility.Cement grinding aid can be greatly lowered in grinding process the electrostatic formed
Absorption bag ball phenomenon, it is possible to reduce the coalescence trend again of the ultra-fine grain formed in grinding process.Cement grinding aid also can
Significantly improve cement fluidity, improve grinding effect and the grinding efficiency of powder concentrator of grinding machine, thus reduce grinding energy.Use
The cement that grinding aid produces has relatively low compacting coalescence trend, thus the handling of beneficially cement, and cement bunker can be reduced
Wall cling phenomenon.As a kind of chemical addition agent, grinding aid can improve concrete scroll and excite aquation power, thus improving water
Mud early strength and later strength.
Domestic most employing technical pure polymerization organic salt and inorganic salt are the main component of grinding aid, relatively costly, technology
Economic indicator is not suitable with practical condition, and product adaptation face is narrower, and the material higher especially for temperature is also the most suitable
Product.Identical product even for different manufacturers is applied to different manufacturers, there is also the situation that difference on effect is bigger.Existing
There is product cannot give full play to this product and improve grinding material adhesiving effect, and fail multiple effective grinding aid components matching one
Rising, thus play optimal grinding effect, cement or concrete can be brought harm by chlorine or alkali in the most existing grinding aid.
