Abstract
The present invention relates to a kind of alundum alumina slurry production methods, the alumina powder and additive mixed effect come for the process bands for solving the problems, such as normal paddle kneading and mud refining is poor, improve the uniformity of slurry by the way of liquid phase mixing, specific method is that water and additive are first dissolved into uniform solution by high-speed dispersing kettle, then alumina powder is added in, powder and liquid is allowed to be uniformly mixed under the action of high speed dispersion dish, then pass through circulating high speed emulsification pump again, by scattered alumina powder, water, the slurry that additive is formed further is homogenized, ultimately form the slurry with fine mobility.The present invention provides a kind of alundum alumina slurry production methods, can effectively improve slurry production effect.The invention is a kind of high fluidity, high solids alumina slurry production method, is used to prepare the alumina slurry of high solids；Slurry is used as a kind of alundum abrasive material after drying, molding, sintering, and using effect is good.
Description
Technical field
The present invention relates to a kind of alundum alumina slurry production methods, belong to slurry production technical field.
Background technology
In conventional alundum production process, to prepare for molding pug, need alumina powder, water and add
Agent is added to be stirred by paddle kneader, then pug mill is homogenized.This mode technological process is long, alumina powder and additive
Mixed effect it is uneven, be not easy to be molded, and final production come out abrasive material lack of homogeneity.
Invention content
The purpose of the present invention is to provide a kind of alundum alumina slurry production method, to improve slurry production
Effect, convenient for preferably using as needed.The invention is a kind of high fluidity, high solids alumina slurry production method,
It is used to prepare the alumina slurry of high solids；Slurry is used as a kind of alundum abrasive material after drying, molding, sintering.
To achieve these goals, technical scheme is as follows.
A kind of alundum alumina slurry production method, to solve the oxygen that normal paddle is mediated and the process bands of mud refining are come
The problem of changing aluminium powder and poor additive mixed effect, improves the uniformity of slurry by the way of liquid phase mixing, and specific method is
It is that water and additive are first dissolved by uniform solution by high-speed dispersing kettle, then adds in alumina powder, powder and liquid is allowed to exist
Be uniformly mixed under the action of high speed dispersion dish, then again by circulating high speed emulsification pump, by scattered alumina powder, water,
The slurry that additive is formed further is homogenized, and ultimately forms the slurry with fine mobility.
Further, in the above method, using high-speed dispersing kettle by alumina powder, water, additive formed slurry.
Further, in the above method, the Scattered Kettle used uses high speed dispersion dish.
Further, in the above method, high speed emulsification pump is made of the rotor that three layers or multilayer antithesis are engaged, and is processed
Material is inhaled into the shear action that rotor bears hundreds of thousands time, and material by shearing, disperseing, emulsifying layer by layer, so that it is guaranteed that multiphase
The effect that liquid height disperses and fixed particle refines rapidly.
The advantageous effect of the invention is：The present invention provides a kind of alundum alumina slurry production method, energy
Effectively improve slurry production effect.The invention is a kind of high fluidity, high solids alumina slurry production method, for making
The alumina slurry of standby high solids；Slurry is after drying, molding, sintering as a kind of alundum abrasive material, using effect
Good, production efficiency is high.
Specific embodiment
The specific embodiment of the present invention is described with reference to embodiment, to be better understood from the present invention.
Embodiment
Alundum alumina slurry production method in the present embodiment, for the technique for solving normal paddle kneading and mud refining
The problem of alumina powder brought and poor additive mixed effect, improves the uniformity of slurry, tool by the way of liquid phase mixing
Body method is that water and additive are first dissolved into uniform solution by high-speed dispersing kettle, then adds in alumina powder, allows powder
It is uniformly mixed under the action of high speed dispersion dish with liquid, then again by circulating high speed emulsification pump, by scattered oxidation
The slurry that aluminium powder, water, additive are formed further is homogenized, and ultimately forms the slurry with fine mobility.
In the above method, using high-speed dispersing kettle by alumina powder, water, additive formed slurry.
In the above method, the Scattered Kettle used uses high speed dispersion dish.
In the above method, high speed emulsification pump is made of the rotor that three layers or multilayer antithesis are engaged, and material to be machined is inhaled
Enter the shear action that rotor bears hundreds of thousands time, material by shearing, disperseing, emulsifying layer by layer, so that it is guaranteed that multi-phase fluid height
The effect that dispersion and fixed particle refine rapidly.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
