Description
Technical field
The present invention relates to a kind of admixture in a kind of manufacture of cement, relate in particular to a kind of cement grinding aid reinforcing agent and preparation method thereof, belong to field of cement production.
Background technology
When carrying out manufacture of cement, usually need to add the admixture of a kind of grinding aid, refinforced cement intensity, to reach the unit output that improves manufacture of cement, the intensity of refinforced cement goods, cost-effective purpose.Existing cement grinding aid reinforcing agent has a variety of, but the effect of its grinding aid, refinforced cement intensity, saving production cost is all not ideal enough.
Summary of the invention
The present invention's technical problem at first to be solved is to overcome the deficiencies in the prior art, provides a kind of except that have good grinding-aid effect in cement production process, and the intensity that still can effectively improve cement products also can be saved the cement grinding aid reinforcing agent of production cost.
Technical problem to be solved by this invention realizes by following technological approaches:
A kind of cement grinding aid reinforcing agent comprises that the component of following weight part is formed: trolamine 0.8-5 part, anhydrous sodium sulphate 20-30 part, flyash 10-18 part, yellow soda ash 6-10 part, sodium-chlor 25-33 part, gypsum 18-25 part, soda ash 8-15 part.
Preferably, the weight part of each component is: 2 parts of trolamines, 25 parts of anhydrous sodium sulphate, 12 parts in flyash, 8 parts in yellow soda ash, 28 parts in sodium-chlor, 20 parts in gypsum, 10 parts of soda ash.
In order to reach better grinding aid reinforced effects, cement grinding aid reinforcing agent of the present invention also can contain the auxiliary material of 1-10 weight part, is preferably 5 weight parts; Described auxiliary material is selected from following any mixture that material is formed with arbitrary proportion more than 3 kinds or 3 kinds: alum, Repone K, anhydrous calcium oxide, glycerol, ethylene glycol, calcium lignin sulphonate, Sodium Nitrite, thionamic acid.
Used all raw materials of the present invention all can be bought from the general chemical shop and obtain, and its specification is a technical grade.
Another technical problem to be solved by this invention provides a kind of method for preparing cement grinding aid reinforcing agent of the present invention.
Another technical problem to be solved by this invention realizes by following technological approaches:
A kind of method for preparing cement grinding aid reinforcing agent of the present invention comprises:
1) takes by weighing each component by following weight part: trolamine 0.8-5 part, anhydrous sodium sulphate 20-30 part, flyash 10-18 part, yellow soda ash 6-10 part, sodium-chlor 25-33 part, gypsum 18-25 part, soda ash 8-15 part;
2) above-mentioned each component polishing is pulverized, cross the 80-120 mesh sieve, mix and promptly get cement grinding aid reinforcing agent of the present invention.
Cement grinding aid reinforcing agent of the present invention is the dark gray powder material, because of compound a small amount of liquid organic material shows slightly moist.Prove that through a large amount of type approval tests this product is obvious to the reinforced effects of blended materials such as slag, zeolite, flyash, volcanic ash.Therefore, be specially adapted to the bigger silicate cement series of mixing material amount, comprise Portland blast, Portland pozzolana cement, Portland fly ash cement, composite Portland cement etc.
Cement grinding aid of the present invention is a kind of special additive that is applied in the manufacture of cement, this grinding aid is a base-material with I and II flyash, adopt physico-chemical process that its grinding-aid effect and activity are improved, add the consumption that to save grog behind this grinding aid significantly, the utilization ratio of industrial residue in increasing, thus reach the double effects that reduces production costs and improve cement quality.
With medium and small sized enterprises that produce 200000 tons per year is example, and after production cement mixed this present invention cement grinding aid 1.0%, its cost savings were calculated as follows (the grog price is by 200 yuan/ton, and the blended material price is per ton by 50 yuan):
1, reduces grog consumption 25%; Increase blending amount of mixture material 24%;
Saving cost per ton: cement clinker unit price * 25%-blended material unit price * 24-(grinding aid unit price ten freight charges) * 1%=200 * 25%-50 * 24%-(1200+50) * 1%=25.5 unit/ton
Annual cost=200,000 ton * 25.5 yuan/ton=5,100,000 yuan saved.
2, reduce grog consumption 15%, increase blending amount of mixture material 14%.
Per ton cost saving=cement clinker unit price * 15%-blended material unit price * 14%-(grinding aid unit price+freight charges) * 1%=200 * 15%-50 * 14%-(1200+50) * 1%=10.5 unit/ton
Annual cost=200,000 ton * 10.5 yuan/ton=2,100,000 yuan saved.
As seen through the above analysis, one produce 200000 tons cement mill per year and infiltrate cement grinding aid of the present invention after, ten thousand yuan of annual escapable cost 210-510, its economic benefit is considerable, and this saving can not bring any change of technology and flow process.
In addition, cement grinding aid of the present invention also has following beneficial effect:
1, improves the cement intensity grade
Under the situation that does not reduce the grog consumption, mix this product of 0.8-1.0wt%, can make 28 days ultimate compression strength of cement improve 8-15Mpa, the also corresponding raising of folding strength.
2, improve the unit-hour output of cement mill
Because this product has good grinding-aid effect, after mixing this product, cement mill unit hour output can improve 10-15wt%, the corresponding decline of unit Cement Production power consumption, increase the industrial residue utilization rate, mix this product after, cement per ton can increase the slag of 14-24wt%, the consumption of waste residue such as number coal ash etc. plays the effect of environmental protection.
Cement grinding aid reinforcing agent of the present invention uses very simple and convenient, when producing cement, mix 0.8-0.1wt% this product, reduce the grog consumption of 12-25wt%, increase the blending amount of mixture material of 11-24wt%, go into mill, levigate getting final product with gypsum then, for the ratio that grog reduces, can determine according to the rich intensity of used grog quality and cement control.
Further describe beneficial effect of the present invention by the following examples, it should be understood that these embodiment only are used for the purpose of illustration, never limit protection scope of the present invention.
