Abstract
The invention relates to a method for purifying a diamond or cubic boron nitride abrasive. The method comprises the following steps: adding sodium hydroxide and potassium hydroxide to diamond or cubic boron nitride containing pyrophyllite silicate, hexagonal boron nitride and silicon oxide; stirring the sodium hydroxide and the potassium hydroxide as well as the diamond or cubic boron nitride for reaction; controlling an internal temperature at 130-150 DEG C and controlling an external temperature range at 240-250 DEG C; 2-4 hours later, closing a heating system; and discharging a product through a discharging product. Through the adoption of the method provided by the invention, product quality is absolutely guaranteed; in addition, uniformity is kept in stirring; a fact that purity reaches reaches requirements of purifying reaction consistency is guaranteed; impurities and incomplete reaction phenomenon are avoided; the sodium hydroxide and the potassium hydroxide are saved by 70 % according to process statistics; the comprehensive cost is reduced by 50 %; and very good promotion and application values are obtained.
Description
Technical field
The present invention relates to the method for a kind of purifying gold hard rock or cubic boron nitride abrasive materials.
Technical background
At present, superhard material manufacturing enterprise is in the chemical purification process, for impurity such as the contained agalmatolite silicate of product, hexagonal boron nitride, silicon oxide, traditional method of purification is mixed material and sodium hydroxide, potassium hydroxide with Stainless steel basin and is used the electric furnace reacting by heating, generate water-soluble salts substances dilute with water and reach the purpose of removing impurity, but processing efficiency is very low, cost is very high, every processing 1 myriagram draws product to need current consumption 5 kilowatt-hours, about 3 hours times spent, about 3 myriagrams of each processing draw, when if output is excessive, also need a large amount of spaces and manpower.
Summary of the invention
The object of the present invention is to provide the method for a kind of purifying gold hard rock or cubic boron nitride abrasive materials, processing efficiency is high, and cost is low.
To achieve these goals, technical scheme of the present invention has adopted the method for a kind of purifying gold hard rock or cubic boron nitride abrasive materials, may further comprise the steps: will contain agalmatolite silicate, hexagonal boron nitride, adding sodium hydroxide and potassium hydroxide carry out stirring reaction in the diamond of silicon oxide or the cubic boron nitride, set inside and outside processing parameter by temperature controller and heating power controller, 130-150 ℃ of internal temperature control, 240-250 ℃ of outside temperature span of control, keep impurity and caustic soda reacting balance safety, control reaction process and response behaviour, keep internal temperature to reach 130-150 ℃, close heating system after 2-4 hours, emit product by discharge outlet.
Described reaction is carried out in stainless steel cauldron.
Adding sodium hydroxide and potassium hydroxide in the cubic boron nitride are carried out stirring reaction.
Add 20-30 kilograms in 50-60 kilograms in sodium hydroxide and potassium hydroxide in described per 100-120 kg cubic boron nitride.
Method of purification of the present invention is to utilize industrial stainless steel cauldron, adopt the Infrared Heating mode, to contain and in stainless steel cauldron, finish chemical reaction after the diamond of agalmatolite silicate, hexagonal boron nitride, silicon oxide or cubic boron nitride mix with sodium hydroxide, potassium hydroxide, reach the purpose of removing agalmatolite silicate, hexagonal boron nitride, silicon oxide.Per 1 myriagram draws power consumption 0.7-0.8 kilowatt-hour, 1000mm*1000mm*2500mm takes up room, primary purification double centner (500000 carats), 3 hours times spent, not only save 85% electric energy, and sufficient reacting, reach the purpose of purification fully, and reduce human cost and improved safety coefficient, arrive automatization control fully.Adopting stainless steel cauldron is not only the change of container, temperature of reaction can accurately evenly be controlled, there is rapid raising the safety operation aspect, type of heating of the prior art is inhomogeneous because being heated, too high 300 ℃ of local temperature may affect quality product because of corrosion, and temperature remains on 130-150 ℃ now, and quality product is had absolute assurance; Stir to keep in addition homogeneity, the consistence of purified reaction is guaranteed that purity reaches requirement, do not have impurity to react incomplete phenomenon, save sodium hydroxide, potassium hydroxide 70% according to purposes of statistical process, comprehensive cost reduces by 50%, has good application value.
