Energy.
Further, the compound hydramine includes triisopropanolamine.Triisopropanolamine produces effect better than three to mentioning for cement
Ethanol amine, and the mobility of cement is improved also superior to triethanolamine, and triisopropanolamine is by promoting early stage congealing property to mention
High early strong effect, and can be by promoting the aquation of difficult hydrated minerals and improving the dispersibility of cement, to improve the rear potent of cement
Fruit keeps mill efficiency higher, cement performance is more preferable with the triethanolamine in triisopropanolamine substitution tradition.
Preferably, the incorporation of the aluminium slag powder grinding aid is the 0.02~0.05% of aluminium slag powder total amount to be ground, with aluminium
Ground-slag plays a role jointly, and aluminium slag powder is made to have good service performance, has preferably dispersibility, so that mobility be made to increase
Add, improves mill efficiency, and each age strength of cement is made to be significantly increased.
Further, the incorporation of the aluminium slag powder grinding aid is the 0.05% of aluminium slag powder total amount to be ground, total with aluminium slag powder
With playing a role, aluminium slag powder is made to have good service performance, there is preferably dispersibility, so that mobility be made to increase, improved
Mill efficiency improves each age strength of cement more.
The preparation method of the aluminium slag powder grinding aid of the present invention for improving intensity, comprising the following steps: according to successively suitable
Sequence sequentially adds water, Nacl, dodium thiosulfate, sodium nitrite, urea, compound hydramine, glycerol, sugar, and one component of every addition is to filling
After dividing dissolution, next component is added.Each component can be made preferably to play a role, and aluminium slag powder is made to have good use
Performance.
The present invention compared with the existing technology has the following advantages that and effect: compound hydramine being replaced in traditional grinding aid and is used for
Increase the triethanolamine of surface-active, and by the interaction of addO-on therapy sugar, so that sugar is played activity, to make mobility
Increase, improve mill efficiency, while each age strength of cement can also be made to be significantly increased, and matching in glycerol and other components
Under conjunction, interaction plays performance, improves cement performance；The mobility of cement is substantially improved, early stage congealing property is promoted to improve
Early strong effect, and the aquation for promoting difficult hydrated minerals and the dispersibility for improving cement can be passed through, to improve the rear potent fruit of cement,
Cement performance is more preferable；It plays a role jointly with aluminium slag powder simultaneously, aluminium slag powder is made to play good service performance.
