Abstract
The cement grinding aid used for cement production consists of triethanolamine 4-20 wt%, ethylene glycol 5 -25 wt%, acetic amine 5-10 wt%, urea 22-26 wt%, unsaturated polyester resin 3-5 wt% and waste paper pulp liquid 36-44 wt%. The present invention can eliminate static electricity during cement ball milling process to raise cement yield and save electric power.
Description
Technical field
The invention belongs to cement and make the field, specifically disclose a kind of component and content of cement grinding aid.
Technical background
In the ball milling operation of manufacture of cement, between the material, the friction between material and the steel ball can make material have static, make material be adsorbed on steel ball surface, cause bag ball phenomenon, reduce grinding efficiency, make cement output and downgrade, the current consumption of unit cement output increases.For eliminating the static that material has, in the mechanical milling process of manufacture of cement, need in material, to add cement grinding aid.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cement grinding aid, can add material to eliminate static in the mechanical milling process of manufacture of cement, improves the cement output in the unit time, reduces the current consumption of unit output.
Technical scheme of the present invention is:
Cement grinding aid closes polyester resin by trolamine, ethylene glycol, Ammoniom-Acetate, urea, insatiable hunger and spent pulping liquor is formed, and the content of each component (mass percent) is
Trolamine 4%-20%
Ethylene glycol 5%-25%
Ammoniom-Acetate 5%-10%
Urea 22%-26%
Polyester resin 3%-5% is closed in insatiable hunger
Spent pulping liquor 36%-44%
The composition of spent pulping liquor is,
Xylogen sodium or xylogen calcium 8%,
NaOH or Ca (OH)
2Account for 0.1-0.5%, all the other are water.
Preparation technology of the present invention is: under centigradetemperature 30 degree conditions, the spent pulping liquor of mass percent 36%-44% is filtered out impurity, the trolamine homogenizing (stirring) of adding 4%-20% 15 minutes, add 22%-26% urea and 5%-10% Ammoniom-Acetate again, homogenizing 15 minutes, add 5%-25% ethylene glycol again and polyester resin is closed in the 3%-5% insatiable hunger, homogenizing 20 minutes is stored to park then and was promptly made finished product in 24 hours.
The invention has the beneficial effects as follows,
(1) improves cement output, under equal working condition, lack than the currently available products consumption.In cement production process, incorporation of the present invention is 2/1.8/10000ths to ten thousand o'clock of feeding capacity, can make cement output improve 10-30%.Below be that the present invention and U.S. Xi Pu company like product are proposed the contrast of output and usage quantity under same working condition.
