Problems solved by technology

The polishing liquid prepared by this method polishes the gemstone ball, and the surface capacity of the ball produces serious surface defects such as scratches, and the surface finish of the ball is poor.
Moreover, due to the uneven dispersion of nano-diamond powder, the concentration of abrasives is also uneven, resulting in difficult control of the size of the ball, the roundness level cannot reach G10, the processing efficiency is unstable, and the experience and technical requirements of production workers are high. Realize batch processing and other issues

Embodiment Construction

[0033] Each component required for the polishing liquid is configured according to Table 2:

[0034] Table 2

[0035]

[0036] The preparation method of the polishing liquid formula is as follows:

[0037] (1) Weighing: Put a layer of clean white paper on the electronic scale, take out the diamond powder with a medicine spoon and place it on the white paper, and accurately weigh the diamond powder according to Table 2.

[0038] (2) Baking: put the white paper filled with nano-diamond powder together on a heating platform, bake at a temperature of 100° C. for 120 minutes, take out the baked nano-diamond powder, and then cool in air for 30 minutes.

[0039] (3) Grinding: In a medium-sized agate mortar, grind and disperse the agglomerated nano-diamond powder, the amount of each grinding should not exceed 2 grams, and the grinding time should not be less than 30 minutes.

[0040] (4) ultrasonic dispersion: the nano-diamond powder after grinding is placed in the beaker, adds t...

Abstract

The invention relates to polishing liquid used for a gem ball with 10-grade surface finish and a preparation method. The polishing liquid consists of the following components in part by weight: 3 to 6 parts of nano-diamond, 240 to 300 parts of stearic acid, 320 to 480 parts of kerosene, and 1 to 1.2 parts of sodium hydroxide. The surface of a workpiece polished by using the polishing liquid of the invention has high surface finishment; an operation method is simple; technical requirements are low; and the polishing liquid is suitable for large-batch production. The polishing liquid prepared by adopting the method of the invention is permanent suspension without precipitate.

Description

technical field [0001] The invention belongs to the field of polishing fluids, in particular to a polishing fluid and a preparation method for a gemstone ball whose surface is polished to grade 10 Background technique [0002] Utilizing the characteristics of artificial sapphire, such as high hardness, wear resistance, small linear expansion coefficient, high compressive strength, acid and alkali resistance, and corrosion resistance, and the transmittance in the 3-5μ band is higher than 85%, it can be made of sapphire All kinds of round balls and blind hole balls. Balls are used in flowmeter ball valves for liquids or gases used in highly corrosive environments, optical fiber communications, etc. Gemstone blind hole balls are used as insulating measuring heads for measuring instruments and precision measuring instruments. Since the Mohs hardness of sapphire reaches 9 and the crystal is anisotropic, the surface polishing quality of sapphire balls reaches the optical level, ...
