Abstract
A kind of ceramic fine bead and manufacture method thereof, the main component of ceramic fine bead are Al
2O
3, it is made under 1500 degree-2500 degree by electric smelting method or forming and sintering method, and Mohs' hardness is not less than 7, and diameter is the ceramic fine bead of 0.3-6mm.This ceramic fine bead mainly with the grinding element of processing ultrafine powder and ultra-fine slurry, also can be used for surface treatment and filtration and contains the solid-liquid body.
Description
The present invention relates to a kind of grinding element of processing ultrafine powder and ultra-fine slurry.
At present domestic top grade paint, printing ink, makeup, pigment, dyestuff, agricultural chemicals etc., most dependence on import, one of its reason is powder wherein to be processed into ultrafine powder with inexpensive method, when domestic processing ultrafine powder and ultra-fine slurry, the Ceramic Balls that industrial common employing diameter 6mm is above, the granulated glass sphere of agate glass ball or diameter 1-3mm, Ceramic Balls, the surface-area that agate glass ball contacts with material is little, mill efficiency is low, glass sphere and material surface in contact are long-pending big, but its hardness is low, and Mohs' hardness only is 7, can not abrasion hardness greater than 7 material and frangible, it is ZrO that France began to produce composition in 82 years
2, SiO
2Ceramic fine bead.
Purpose of the present invention be exactly the ultrafine powder grinding element that a kind of diameter of producing with electric smelting method or shaping sintering process is provided in order to solve the deficiencies in the prior art is 0.3-6mm be ceramic fine bead.
Technical solution of the present invention is as follows:
A kind of ceramic fine bead, it is made by electric smelting method or shaping sintering process, and the weight percent content of its major ingredient is:
Al
2O
370-99%
The additive surplus
The diameter of its finished particle is 0.3-6mm.
A kind of manufacture method of ceramic fine bead, it is made by balling-up sintering in electric arc furnace electric smelting or the nodulizer, and main raw material is Al in electric smelting or sintering process
2O
3, temperature is controlled at 1500 degree-2500 degree, promptly gets product after the cooling.
The invention has the advantages that but adopting electric smelting or shaping sintering process to make diameter is the hard material of the ceramic fine bead abrasion hardness of 0.3-6mm greater than Mohs 7 degree, momentum is big, and the mill efficiency height is corrosion-resistant, wear-resistant, high temperature resistant, and shock resistance is difficult for broken.
The invention will be further described below in conjunction with embodiment, and additive of the present invention and weight percent thereof are:
CaO 0-20%
SiO
20-20%
ZrO
20-30%
BaO 0-10%
MgO 0-10%
Embodiment 1: the best proportioning of each composition of the present invention is:
Al
2O
380%
CaO 2%
SiO
23%
ZrO
27%
BaO 3%
MgO 5%
Put into electric arc furnace after above-mentioned each composition mixed and carry out sintering after electric smelting or the nodulizer balling-up, during electric smelting, the optimum temps in the electric arc furnace is controlled at 2000 degree-2500 degree, and high-temperature fusion promptly gets the ceramic particle that diameter is 0.3-6mm after becoming the microballon cooling; During sintering, optimum temps is controlled at 1500 degree-1700 degree sintering, promptly gets the ceramic particle that diameter is 0.3-6mm after the cooling.
Embodiment 2: the proportioning of each composition of the present invention also can be:
Al
2O
370%
CaO 5%
SiO
25%
ZrO
210%
BaO 3%
MgO 7%
Its manufacture method is with embodiment 1.
Embodiment 3: the proportioning of each composition of the present invention also can be:
Al
2O
390%
CaO 2%
SiO
23%
ZrO
23%
BaO 1%
MgO 1%
Its manufacture method is with embodiment 1.
The present invention also can be used for surface treatment and filters the filler that contains in solid-liquid body and the chemical industry equipment mainly as grinding element.
