Abstract
The invention relates to a grinding-assistant reinforcing agent for mineral powder. The grinding-assistant reinforcing agent is mainly composed of molasses, triethanolamine, triisopropanolamine, mixed dibasic alcohol, sodium acetate, sodium hydroxide and water. By the adoption of the grinding-assistant reinforcing agent for mineral powder, which is disclosed by the invention, powder grinding efficiency can be improved, grinding machine yield is improved by 10-15%, the specific surface area of mineral powder is improved, and the activity index of the mineral powder is improved.
Description
Technical field
The present invention relates to a kind of breeze grinding aid reinforcing agent of blast-furnace cinder micro-powder manufacture field, belong to grinding aid field in cement and the slag micropowder processing.
Background technology
Slag is the byproduct when smelting the pig iron, has higher lateral reactivity, and the annual slag output of China has more than 100,000,000 ton, if these slags can not get effective utilization, will inevitably cause pollution difficult to the appraisal to environment, also will cause huge energy dissipation.At present, slag is as the blended material of cement with in order to outside the operating mine slag cement, and particularly ground slag has become one of requisite component of preparation high performance concrete as mineral admixture.Slag micropowder has become produces one of high-quality cement, configuration high-performance, large volume, concrete first-selected material of long lifetime.The concrete that is mixed with slag micropowder has that hydration heat is low, corrosion-resistant, good fluidity, later strength height, anti-micro, can make characteristics such as concrete interface adhesive property improvement, is defined as one of ten new technologies of construction industry by nation-building portion.Owing to scoriaceous vitreous structure reason, common grinding aid joins in the slag milling process, though can remove the agglomeration around the slag particle, can not improve the grindability of slag particle itself, so grinding-aid effect is often not good.
But slag in use exists grindability poor, and early strength is on the low side, has restricted scoriaceous applying.Can improve mill efficiency though prolong the grinding time, but increased power consumption, increased the grinding cost, in scoriaceous grinding process,, produce the difference of electron density in grinding process simultaneously because material is subjected to the influence of various power to cause the electrovalent bond of granule interior to rupture, form a series of staggered active sites in the section both sides, they attract each other, make surface of fracture trend towards compound and material is reunited, thereby grinding output and quality are descended significantly.
For reducing the grinding energy consumption, stop the healing of slag surface of fracture and reducing agglomeration, using grinding aid is the most simple way, uses suitable grinding aid can improve mill efficiency about 10%.
Research on cement additive and use abroad just begin as far back as the thirties in last century, carried out extensive work, many patents have been applied for, domesticly just study and use from the fifties, the most value of the grinding aid of studying and using both at home and abroad are expensive at present, the source shortage, and not remarkable to the slag grinding-aid effect, to slag properties do not have improve or the improvement effect little, thereby generally apply and be restricted.
CN100357214C adopts glycol ether, trolamine, dispersing agent NNO, pearlstone, Sodium sulfate anhydrous.min(99), Tai-Ace S 150 to obtain powder slag cement toughener, and addition is 0.5%, and this product is mainly used in slag cement.
A kind of slag composite activated grinding aids of CN100404456C invention adopts trolamine, polycarboxylate water-reducer and compound with the calcium hydroxide saturated solution, forms through magnetization.This product adopts that trolamine reaches 40%, polycarboxylate water-reducer 20%, saturated aqua calcis 40%.On the one hand cost is too high, and calcium hydroxide has only 0.17% in the saturated on the other hand aqua calcis, is difficult to play the effect of calcium hydroxide, and the magnetization product iron ware of packing into, the magnetic easily dissolved.
The disclosed blast furnace slag liquid grinding aid of CN101597655A, form by glycol ether, sucrose slag waste liquid, sorbyl alcohol, glycerine, tripoly phosphate sodium STPP, yellow soda ash and water, each constituent mass per-cent: glycol ether 10%～20%, sucrose slag waste liquid 10%～15%, sorbyl alcohol 10～20%, glycerine 10-20%, tripoly phosphate sodium STPP 1～5%, yellow soda ash 1～10%, surplus are water.But when using the slag grinding aid, guarantee ore grinding slag water content between 0.5～1.0% as far as possible, moisturely all can influence scoriaceous mill efficiency too greatly or too little.In actual production process, go into to grind scoriaceous moisture and be difficult to be controlled in 0.5% scope.
The technical scheme that CN101781690A adopts is: comprising: trolamine 15～20%, wooden calcium 10～15%, modulus are 1.75～2.1 water glass 15～20%, water 45～55%.When adding other composition in the water glass, can condense usually, form similar cotton globular precipitate, cause and to use.
Summary of the invention
In order to improve mill grinding efficiency, increase the activity index of slag micropowder, adopt raw material easily to purchase and cheaply, it is few to have volume simultaneously, and liquid meter adds characteristics such as convenient, and a kind of breeze grinding aid reinforcing agent of the present invention is adsorbed on particle surface shielding particulate surface residual electric charge, prevent the coalescent of powder, stop section to overlap, reduced agglomeration, thereby helped improving the fineness of slag powders; Simultaneously, can excite the activity of breeze, improve the hydration rate of slag cement, promote further densification of hardened cement paste.Therefore, a kind of breeze grinding aid reinforcing agent of the present invention can grinding aid improve output, can improve ore powder granularity again, increases the breeze activity.
A kind of breeze grinding aid reinforcing agent of the present invention is made up of molasses, trolamine, tri-isopropanolamine, mixing dibasic alcohol, sodium-acetate, sodium hydroxide and water.Consist of by mass percentage: molasses 3-8%, trolamine 5-10%, tri-isopropanolamine 3-5%, mixing dibasic alcohol 30-40%, sodium-acetate 3-8%, sodium hydroxide 1-2%, water surplus, preferred mass percent consists of, molasses 5%, trolamine 8%, tri-isopropanolamine 4%, mixing dibasic alcohol 32%, sodium-acetate 5%, sodium hydroxide 1%, water 45%.
A kind of breeze grinding aid reinforcing agent advantage of the present invention is:
1, adopts the mixing dibasic alcohol, mix dibasic alcohol and mainly form, make ethylene glycol and glycol ether play synergy by ethylene glycol and glycol ether.
2, adopt low-cost byproduct molasses, both reduced cost, product performance are improved.
3, the consumption of trolamine, tri-isopropanolamine reduces significantly, product cost is reduced greatly, and product performance is enhanced.
