Problems solved by technology

[0002] Diamond wire saws are divided into resin diamond wire saws and electroplated diamond wire saws. Electroplated diamond wire saws have the advantages of low single-chip wire consumption, smaller wire diameter specifications, and higher cutting efficiency. The same thickness of resin diamond wire saws has the same breaking force and The consolidation strength is far lower than that of electroplated diamond wire saws, and its development potential for thinning wires is also much lower than that of electroplated diamond wire saws. Electroplated diamond wire saws are more in line with the development prospects of future diamond cutting wire thinning. In the production of sanding bath, it is necessary to add anionic dispersant to the sanding bath to improve the sanding and dispersing performance of diamond. After the anionic dispersant is decomposed, the residual organic matter accumulates to a certain amount, which will cause the organic content in the sanding bath to be too high, making the diamond The coating of the wire saw becomes hard and brittle, and the fracture increment of the diamond wire saw is low, which affects the product quality

Embodiment 1

[0018] First pump the untreated sand plating solution to the activated carbon treatment cylinder, raise the temperature to 50°C, and then add 1.5g / L activated carbon to the activated carbon treatment cylinder. The activated carbon is coconut shell activated carbon with a moisture content of ≤20%. Activated carbon with low water content can reduce the amount of activated carbon used. Turn on two mechanical agitators to enhance the contact opportunity between activated carbon and plating solution, which is beneficial to the removal of organic impurities. Stir for 4 hours, let it settle for more than 2 hours, and the activated carbon is deposited in the activated carbon treatment. At the bottom of the tank, clean the activated carbon and recover it with a special bucket, pump the supernatant plating solution to the filter tank for filtration, pump the plating solution to the electrolysis tank after filtration, raise the temperature of the plating solution to 50°C, set the electroly...

Abstract

The invention belongs to the field of electroplating diamond wires, and particularly discloses a treatment method of a sand plating solution on an electroplating diamond fretsaw. The method comprises the following steps of pumping the sand plating solution into an activated carbon treatment cylinder, heating, adding a cationic active agent into the activated carbon treatment cylinder, stirring, neutralizing, adding activated carbon, stirring for a certain time, standing for settling, filtering, transferring filtrate into an electrolytic cylinder, heating, electrolyzing, filtering electrolyte after electrolysis to obtain a purified sanding plating solution, finally, tabletting to detect the content of a dispersing agent in the plating solution, measuring the content of an organic impurity agent in the plating solution by using ultraviolet spectrophotometry, measuring and detecting non-additive parameters of the sanding plating solution, and neutralizing excessive anionic dispersants and cationic active agents in the sanding plating solution to form flocculates. According to the method, the subsequent activated carbon adsorption treatment is facilitated, the purification effect of the sanding plating solution is improved, the tolerance of the treated sanding plating solution to the dispersants is enhanced, the fracture increment of a production line is high, the product quality is improved, the service life of the plating solution is prolonged, and the production cost is reduced.
