Abstract
The present invention relates to a kind of suitable in kaolinic powder grinding aid, especially relate to a kind of powder grinding aid suitable in Kaolin micropowder, belong to Kaolin micropowder grinding technology field。It is be prepared from by weight by following substances: polyalcohol amine 1～5 part, Polyethylene Glycol 1～10 part, polyacrylamide 5～15 parts, sodium pyrophosphate 1～15 part, wollastonite in powder 20～50 parts。Grinding aid of the present invention is composited by a kind of mining industry raw material and common industrial chemicals, and raw material ample supply and prompt delivery are easy to get, low toxicity, non-volatile, and production and processing is simple, with low cost；Kaolin grinding manufacturing enterprise uses this invention grinding aid, simple to operation；Grinding aid of the present invention is while improving mill efficiency, reducing energy consumption, moreover it is possible to effectively reducing Kaolin micropowder surface can, it is to avoid particle agglomeration, improves its fineness, improves the mobility of product, and does not affect Kaolin whiteness。
Description
Technical field
The present invention relates to a kind of suitable in kaolinic powder grinding aid, especially relate to a kind of powder grinding aid suitable in Kaolin micropowder, belong to Kaolin micropowder grinding technology field。
Background technology
Kaolin is a kind of nonmetallic minerals, purposes is very extensive, it is mainly used in papermaking, pottery and refractory material, secondly for coating, gum filler, frit for porcelain enamel and white cement raw material, on a small quantity for industrial departments such as plastics, paint, pigment, emery wheel, daily cosmetics, soap, chemical industry, building materials。Kaolinic all application all have to pass through processing, becomes micropowder, just can join in other materials, merge completely。
In order to obtain Kaolin micropowder, generally require the Kaolin grinding long period, so not only increase energy consumption, and increase mechanical wear rate。Meanwhile, along with the prolongation of grinding time, material specific surface area is gradually increased, and its specific surface area can also increase, and surface can be in energy labile state, causes that subparticle flocks together, and produces agglomeration, and namely granule is thicker。One fine solution to the problems described above uses grinding aid exactly, but the grinding aid used both at home and abroad at present is not only expensive, source shortage, and volume is bigger than normal, and quality is uneven, it is impossible to comprehensively improve grinding process, it is common to promotes and is restricted。CN103666374A " a kind of grinding aid special for coal-measure hard kaolin ", this patents state uses flyash as the carrier of grinding aid, although the use of flyash make use of trade waste, reduce cost, but flyash also have impact on kaolinic whiteness, reduce kaolinic quality。CN101890319B " preparation method of a kind of coal hard kaoline liquid grinding aid ", this patents state uses using triethanolamine as dispersed component in grinding aid, it is known that, along with economic development, the energy starts shortage, triethanolamine not only price rises year by year, and the source of goods is not as stable, causes that the use of triethanolamine is restricted。
Summary of the invention
For the problems referred to above overcoming prior art to exist, the invention aims to provide one not only can reduce Kaolin micropowder surface can, avoid particle agglomeration, improve its fineness, improve the mobility of product, energy consumption can also be reduced, improve mill efficiency, the easy to use powder grinding aid being applicable to Kaolin micropowder。
To achieve these goals, the technical solution adopted in the present invention is a kind of powder grinding aid suitable in Kaolin micropowder, and it is prepared from by polyalcohol amine, Polyethylene Glycol, polyacrylamide, sodium pyrophosphate and wollastonite in powder；The parts by weight of each material are: polyalcohol amine 1～5 part, Polyethylene Glycol 1～10 part, polyacrylamide 5～15 parts, sodium pyrophosphate 1～15 part, wollastonite in powder 20～50 parts。
The parts by weight of each material described are: polyalcohol amine 1～3 part, Polyethylene Glycol 1～5 part, polyacrylamide 5～10 parts, sodium pyrophosphate 5～10 parts, wollastonite in powder 25～50 parts。
Described polyethylene glycol relative molecular weight Mr≤600。
Described polyacrylamide fineness is 100 order～200 orders。
A kind of powder grinding aid suitable in Kaolin micropowder adopts customary preparation methods as above, is mixed by above-mentioned substance according to proportioning, stirs and obtain Kaolin micropowder powder grinding aid。
When the powder grinding aid being applicable to Kaolin micropowder as above uses, it adds in grinding machine with the volume of Kaolin weight 0.2～0.6%, can reach to save power consumption, improve mill efficiency, improve fineness of the particles, reduce the effect of particle agglomeration。
The present invention compared with prior art has the advantage that
1, grinding aid of the present invention is composited by a kind of mining industry raw material and common industrial chemicals。Raw material ample supply and prompt delivery, are easy to get, and low toxicity is non-volatile, and production and processing is simple, with low cost；
2, Kaolin grinding manufacturing enterprise is easy to use, it is only necessary to a weighing balance, together adds grinding machine grinding by volume after weighing with Kaolin；
3, grinding aid of the present invention is while improving mill efficiency, reducing energy consumption, moreover it is possible to effectively reducing the trickle powder surface of Kaolin can, it is to avoid particle agglomeration, improves its fineness, and does not affect Kaolin whiteness。
Detailed description of the invention:
Below in conjunction with specific embodiment, the present invention is further elaborated, but protection scope of the present invention is not limited by specific embodiment, be as the criterion with claims。It addition, with under the premise of technical solution of the present invention, any change or change that those of ordinary skill in the art made for the present invention easily realize fall within scope of the presently claimed invention。
