Abstract
The invention provides a cement grinding aid. The cement grinding aid comprises raw materials as follows: triethanolamine, polyether polyol, sodium hydroxide, sodium thiosulfate and a biochemical waste liquid, wherein the biochemical waste liquid is one of or a mixture of a waste liquid produced during production of industrial sodium gluconate and a waste liquid produced during production of an industrial itaconic acid product. The cement grinding aid can optimize the cement grain composition, activate the early strength of cement, improve the powder grinding efficiency of the cement and reduce energy consumption.
Description
Technical field
The present invention relates to technical field of cement production, particularly a kind of cement grinding aid.
Background technology
In the grinding process of cement clinker, add a small amount of additional substance (material of liquid or solid), can significantly improve mill efficiency or reduce energy consumption, and don't this chemical additive additional substance of infringement cement performance is commonly referred to as cement grinding aid.At present, the cement grinding aid of studies in China and application, have liquid grinding aid and solid grinding aid, its basal component mostly belongs to organic surface-active substance.Be mainly: amine, alcohols, alcamines, lignin sulfonate, lipid acid and its esters, alkyl sulfonates etc.Concrete material is: trolamine, diethanolamine, ethylene glycol, sulfonated lignin, formic acid, stearic acid, oleic acid, urea, Sodium dodecylbenzene sulfonate etc.What reality was selected in manufacture of cement mainly contains two class forms: one is the Chemicals that purity is higher; Two is the waste materials in chemical plant etc.
The kind of cement grinding aid product is more, except pure compound product, also studies and develops multiple composite grinding aids.The object of interpolation grinding aid is the grindability in order to improve material, alleviates the adhesive aggregation conglomeration effect between particle, eliminates subparticle and sticks with paste ball paste liner plate phenomenon, improve the mobility of material in grinding machine, thus realize the target of ball grinder saving energy high yield.
But existing grinding aid procurement price is higher, and composition is indefinite, be difficult to the adaptability adjusting cement in time.Simultaneously in the early strength of cement, time of coagulation, the indexs such as water requirement all cannot reach good effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of cement grinding aid, cement granules grating can be optimized, excited cement early strength, improve cement grinding efficiency, reduce energy consumption.
Technical scheme of the present invention is: a kind of cement grinding aid, comprises the raw material of following weight percent:
Biochemical waste liquid of the present invention is produce one in the waste liquid of the cerelose acid waste liquid of sodium, manufacture methylene-succinic acid product or mixing, and blending ratio is arbitrary proportion.Containing a small amount of Sunmorl N 60S, methylene-succinic acid in biochemical waste liquid, simultaneously containing a large amount of metallic elements and cement activation composition.
The present inventor studies discovery, is added by above-mentioned biochemical waste liquid after preparing cement grinding aid, effectively can improve the time of coagulation of cement, the performance index such as water requirement.Therefore the present invention also provides biochemical waste liquid producing the application in cement grinding aid.
Trolamine described in the present invention, polyether glycol, sodium hydroxide, Sulfothiorine are technical grade product.
The preparation method of above-mentioned cement grinding aid is: (1) is first by biochemical waste liquid and sodium hydroxide hybrid reaction; Object carries out modification to the composition in biochemical waste liquid.
(2) Sulfothiorine is added part water, be mixed with sodium thiosulfate solution, then join in the mixture of step (1), stir.Sodium thiosulfate solution concentration, without concrete restriction, adds suitable quantity of water wiring solution-forming.
(3) by the water of trolamine, polyether glycol and surplus, join in the mixture of step (2), stir.
The present invention has following beneficial effect:
1, under the immovable condition of grinding machine situation, mill output amplitude 10-30% can be improved, can effectively reduce over grinding phenomenon simultaneously, optimize cement granules grating;
2, under maintaining the constant or condition increased production by a small margin of former mill output, improve cement fineness and specific surface area, make strength of cement improve 3-5Mpa;
3, can improve the dispersiveness of material in mill, mill phenomenon stuck with paste by electrostatic adhesion and the bag ball of effectively eliminating cement subparticle;
4, improve the mobility of cement, improve the efficiency of handling equipment;
5 and adopt biochemical waste liquid, can protection of the environment and the cyclic utilization of waste, not only reduce the effect that cost also plays energy-saving and emission-reduction.The waste liquid that biotechnology industry produces, due to its complicated component, is difficult to reasonably be utilized.Its effective constituent of energy Appropriate application of the present invention, makes it play the distinctive activation performance of cement, while effectively enhancing product performance, plays save energy, the good result of recycle.
