Description
Technical field
The invention belongs to purifying super-hard materials technical field, in particular to a kind of cubic boron nitride washes material method.
Background technique
Cubic boron nitride (cBN) is lazy with the high rigidity for being only second to diamond and better than the thermal stability of diamond and chemistry
Property, being used as superabrasive is made various grinding wheels and cutter, for the processing of ferrous material, has efficient, accurate, energy conservation
The advantages that with automation, is especially high-accuracy manufacture field in modern times processing and is widely used.
Up to the present, the cBN cleaning after shaping mainly manually rushes WATER-WASHING METHOD repeatedly, i.e., every 3 myriagram of basin charge is drawn, and adds
Water is stirred, precipitates, is poured out, repeatedly until the water after washing material reaches neutral.This method advantage is easy to operate, the disadvantage is that
Manpower is consumed very much, is once fed intake few, water consumption is big, and the used time is longer, is unfavorable for industrialized production.
Summary of the invention
In view of the above technical problems, material method is washed the purpose of the present invention is to provide a kind of cubic boron nitride.This method
Material method is washed for automation, can be improved labor efficiency, labor intensity is reduced, is conducive to industrialized production.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of cubic boron nitride washes material method, comprising the following steps:
(1) cubic boron nitride after shaping is put into material washing machine, and the hydrochloric acid that mass concentration is 37% is added, and after mixing evenly, is stood
1h；
(2) after standing, water is added in material washing machine, the acidity of solution in material washing machine is diluted, then liquid is poured out；
(3) material washing machine is put into supersonic wave cleaning machine, adjusts the height of drinking-water pipe downlink in material washing machine, started material washing machine, press
According to the order work for adding water-forward direction stirring-reverse agitating function-is static-to draw water；
(4) after step (3) recycles at least 3 times, supersonic wave cleaning machine is opened, step (3) are continued cycling through；
(5) pH and conductivity of solution in material washing machine are tested, pH is neutrality, and conductivity≤3 terminate cleaning；
(6) cubic boron nitride in material washing machine is taken out, is placed in dryer, first rinsed with room temperature pure water, after drying again with 60 ~
100 DEG C of pure water rinses.
As currently preferred, height of the end of drinking-water pipe apart from charge level is not less than 5mm in the step (3), takes out
CBN granularity≤500 mesh in water out.In the present invention, the height of drinking-water pipe downlink is height of the end apart from charge level of drinking-water pipe
Degree, the distance of the high discharge feed side in the end of specially drinking-water pipe.
As currently preferred, constant process parameters in the step (3) are as follows: 200 ~ 220s of water time, forward direction is added to stir
Time 150s, reverse agitating function time 20s are mixed, time of pumping is not less than 100s；The technological parameter of variation: the end distance of drinking-water pipe
Height, quiescent time, the cycle-index of charge level.Technological parameter is changed to be set according to different cultivars, granularity, Ball-milling Time.
As currently preferred, the cubic boron nitride of at least 90,000 ct can be once cleaned in the material washing machine.
It is shinny that cBN of the invention washes the cBN single-crystal surface that material method obtains, and it is not in plate after drying that conductivity, which reduces,
Knot, phenomena such as tumor will not be played when being made into product, is bubbled, falls off.
Compared with prior art, the invention has the benefit that
1, it is of the invention wash that material method significantly improves cubic boron nitride wash material efficiency, this method can once be washed till few 9 myriagrams
Material is drawn, and tradition washes material method once and can only wash 3 myriagrams drawing material.
2, material method of washing of the invention washes material equipment using intelligence, can significantly reduce labor intensity.
3, the clean level for washing material method energy intuitive judgment material during washing material of the invention.
