Abstract
The invention belongs to an additive in the mineral powder preparation field and particularly relates to a high-yield energy-saving type slag grinding aid. The high-yield energy-saving type slag grinding aid is prepared from the following raw materials in percentage by weight: 10-20% of diethanolisopropanolamine, 10-18% of propylene glycol, 2-7% of sodium tripolyphosphate, 8-15% of polyacrylamide, 15-20% of polyether, 2-7% of sodium gluconate, 10-15% of a stabilizer and the balance of water. By adding the grinding aid into slag grinding, the output per machine is improved by 30.22% at most, the yield amplitude is greatly improved, and the energy consumption is obviously reduced.
Description
Technical field
The invention belongs to breeze admixture technical field, particularly a kind of high yield and saving energy type slag grinding aid.
Background technology
Slag is a kind of byproduct that steel smelting procedure produces, and in order to efficent use of resources, uses after usually being worn into fine powder as slag micropowder.Slag micropowder is new green environment protection product, effectively can not only utilize blast-furnace metallurgical slag, turn waste into wealth, and also plays promoter action to the occupation of land of reduction slag, minimizing environmental pollution.Slag micropowder has become one of production high-quality cement, configuration high-performance, long lifetime concrete first-selected material.The concrete being mixed with slag micropowder has that hydration heat is low, corrosion-resistant, high, the anti-micro of good fluidity, later strength, can make the features such as concrete interface adhesive property improvement, is defined as one of construction industry ten new technologies by Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD).
Because slag is stone, need in fine grinding process to consume a large amount of energy and production time.Main ethylene glycol or the mixture containing ethylene glycol of adopting of the formula composition of existing liquid slag grinding aid is as grinding aid.But due to the vitreous structure reason of slag, grinding aid of the prior art joins in slag milling process, although the agglomeration around slag particle can be removed, the grindability of slag particle itself can not be improved, so grinding-aid effect or not ideal enough.And along with the minimizing day by day of Mineral resources, and large-lot producer is serious to the consumption of the energy, how to improve the difficult problem that unit-hour output and save energy also become this area.For this reason, seeking a kind of high yield and saving energy type slag grinding aid product is domestic grinding aid industry problem in urgent need to solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high yield and saving energy type slag grinding aid, and in slag milling, mix this grinding aid, unit-hour output improves greatly, and energy consumption significantly reduces.
For achieving the above object, the present invention adopts following technical scheme:
A kind of high yield and saving energy type slag grinding aid, be made up of the raw material of following weight percent:
Above-mentioned one package stabilizer can be dispersion agent NNO (methylene-bis bitter edible plant sodium sulfonate) and/or Dispersant MF (dispersing agent MF), be preferably dispersion agent NNO and Dispersant MF is composite forms, the weight ratio of dispersion agent NNO and Dispersant MF is (2 ~ 4): 1.
Preferably, the weight ratio of above-mentioned dispersion agent NNO and Dispersant MF is 3:1.
Preferably, high yield and saving energy type slag grinding aid of the present invention, be made up of the raw material of following weight percent:
In formula material of the present invention, di-alcohol monoisopropanolamine, as hardening accelerator, ensures the intensity of slag, has good grinding-aid effect simultaneously; The end group of propylene glycol is an aliphatic group, has good dispersiveness, is conducive to the mobility of powder, and comparatively di-alcohol monoisopropanolamine is strong for the grinding-aid effect of propylene glycol, substitutes di-alcohol monoisopropanolamine, make grinding-aid effect more with propylene glycol; Tripoly phosphate sodium STPP has good dispersiveness, can prevent slag powder bag ball, stick with paste ball, attached integrated group, improve mill efficiency, reduce energy consumption; Polyacrylamide has lubrication, reduces the resistance of grinding, improves the mill efficiency of powder; Polyethers can lubricate powder, improves the mobility of powder, thus improves the efficiency of powder, improves unit-hour output, reduces energy consumption; Sunmorl N 60S has unusual effect to the mobility improving powder; Add stablizer, the permanent stability of grinding aid can be ensured, also there is powerful dissemination simultaneously, effectively promote mill efficiency.
Beneficial effect of the present invention is:
1, in formula of the present invention, each raw material plays synergistic effect, can improve 30.22% unit-hour output, reduces energy consumption, accomplishes high yield and saving energy.
2, grinding aid of the present invention is watery thing, makes each component more even, more can strengthen grinding effect, improve mill efficiency, reduce energy consumption.
3, needed for grinding aid of the present invention, output is few, only need mix 0.02 ~ 0.05%, just can have good high yield and saving energy effect.
