Abstract
The invention discloses a method for rapidly removing solid impurities in zirconia microspheres. The method includes the steps that firstly, the zirconia microspheres including the solid impurities are put into a drying box, and moisture of the zirconia microspheres is dried; secondly, standard screens with different mesh numbers are used for screening the dried zirconia microspheres in a classified manner, and the impurities are removed; thirdly, the screened zirconia microspheres and the impurities which are not removed are put into a fast grinder to be automatically ground with added water; and fourthly, the automatically-ground zirconia microspheres are screened again in a classified manner and rinsed, and therefore the clean zirconia microspheres can be obtained after drying after cleaning is over. Equipment and tools used in the method are simple; and the method is convenient to operate, obvious in impurity removing effect, capable of greatly reducing cost and reducing waste and very good in economic benefit.
Description
Technical field
The invention belongs to ultra-fine powder technology field, be specifically related to extra-fine grinding dielectric clean technology.
Background technology
Zirconia microballon, also known as zirconia ceramics ball, has the premium properties such as high strength and high tenacity, wearability are good, corrosion-and high-temp-resistant at normal temperatures.High-purity zirconia pearl is that grinding matter ideal is at present situated between, and has now been widely used in extra-fine grinding and the dispersion of the industry materials such as nonmetallic ore, battery, coating, ink, paint, dyestuff, titanium dioxide, agricultural chemicals, magnetic material.
At present, zirconia microballon on market has plurality of specifications (single bead diameter 0.05 ~ 13mm), the zirconium pearl diameter being generally used for roughly grinding is between 5mm to 13mm, for the diameter of fine grinding between 1mm to 3mm, wanting to obtain submicron order powder product just needs the zirconia microballon being less than 1mm with diameter to grind.Along with the fast development of nanometer technology, all trades and professions are more and more thinner to the granularity requirements of powder product, ceramic ink jet printing ink as fiery in market anomalies in recent years, require that in ink, particle size distribution is even, median D
50be less than 300nm, this just needs the zirconium pearl being less than 0.5mm with diameter to carry out the process of grinding homogenizing to it, and portioned product even needs to grind with the zirconia microballon of 0.3mm or 0.1mm.
Because raw material expensive price, the technique of producing zirconia microballon are comparatively complicated, zirconia microballon market price is caused to remain high.Yttrium stable zirconium oxide microballon market price as domestic diameter 2.0 ~ 2.5mm is about 140 yuan/kilogram, the yttrium stable zirconium oxide microballon market price of diameter 0.3mm is about 300 yuan/kilogram (in April, 2015), and Japanese, German import yttrium stable zirconium oxide microballon price is higher.
When actual production and maintenance of equipment, be often easily mixed into broken granule in zirconia microballon accumulation body, solid impurity as common in sheet rubber, wood chip, silt etc., and then affect the purity of abrasive product.When these impurity are mixed in diameter 1mm zirconia microballon, relatively easily remove.But be usually difficult to remove after granule impurity is mixed into diameter 0.5mm and following zirconia microballon, manual sorting's removal of impurities is wasted time and energy, and is difficult to clean out, and is usually done by the zirconia microballon being mixed into impurity and scraps process, significantly increase production cost.
Summary of the invention
The object of the present invention is to provide the method for solid impurity in a kind of quick removal zirconia microballon, utilize high strength and the wearability of material sieving technology and zirconia microballon, remove the solid impurity be mixed into and obtain clean zirconia microballon, greatly reduce costs, cut the waste, there is significant economic benefit.
The object of the invention is to be achieved by the following technical programs: a kind of method of solid impurity in quick removal zirconia microballon, first the zirconia microballon containing moisture and solid impurity is put into baking oven, its moisture is dried; By utilizing the standard screen of different meshes, the zirconia microballon after oven dry and solid impurity are sieved, removal of impurities; Zirconia microballon after screening and remaining residue impurity are put into grind to add water fast and carry out autogenous grinding; Zirconia microballon after autogenous grinding sieves again, rinsing, and cleaning terminates post-drying and namely obtains clean zirconia microballon, comprises following concrete steps:
(1) the described zirconia microballon containing impurity is put into baking oven, dry surface moisture, its mobility is strengthened, is convenient to sieve;
(2) sieve dried zirconia microballon, removing is greater than zirconia bead diameter maximum and is less than the solid impurity of its diameter minimum of a value, makes residual impurity granular size within zirconia microballon particle size distribution range;
(3) the zirconia microballon after screening and the impurity do not removed are put into grinder to add water and carry out autogenous grinding;
(4) the zirconia microballon after autogenous grinding sieves again, rinsing;
(5) sieve, clean and terminate post-drying, obtain clean zirconia microballon;
(6) according to the clean level of final zirconia microballon, step (1) ~ (5) can be repeated.
The further technical scheme of the present invention also has following characteristics:
In described step (1), after the drying of zirconia microballon, moisture is less than 0.05%.
Adopt 2 grade standard screen clothes in described step (2), wherein higher level's mesh size is greater than zirconia bead diameter, is convenient to retain large granular impurity, by zirconia microballon.Subordinate's mesh size is less than zirconia bead diameter, is convenient to retain zirconia microballon, removes granule impurity.
The zirconia microballon gross mass participating in wet method autogenous grinding in described step (3) is greater than 500g, and water polo is 1:5 ~ 1:1 than scope.
The grinder adopted in described step (3) is grind fast, and rotating speed is not less than 500rpm.Zirconia microballon gross mass (gram) and quick barreling mill chamber volume ratio (liter) scope are 500:1 ~ 2000:1, and milling time determines according to the clean-up performance of zirconia microballon.
The same step of screen method (2) in described step (4).
Beneficial effect: the present invention adopts simple material sieving technology to carry out removal of impurities to solid impurity, utilizes the high strength of zirconia microballon and wearability thoroughly to grind the impurity be mixed into, again sieves, cleans the rear zirconia microballon that just can obtain cleaning.Simply, simple operation, impurity-eliminating effect is obvious, greatly can reduce costs, cut the waste, have good economic benefit for the equipment that the present invention uses and instrument.
Detailed description of the invention
Diameter 0.22 ~ 0.28mm yttrium stable zirconium oxide microballon of existing Handan manufacturer production is mixed into the solid impurities such as sheet rubber, silt, filter cloth bits, and adopt the present invention to clear up it, cleanup step is as follows:
