preparation example Construction

[0036] The preparation method of special grinding fluid, concrete steps are as follows:

[0037] ②Heat engine oil and lard to 60°C to melt and mix for later use;

[0038] ② Add benzotriazole, chlorinated fatty acid, and emulsified silicone oil to some distilled water, heat to 50°C, stir and fuse, and cool for later use;

[0039] ③At room temperature, add fatty acid diethanolamide, sodium naphthenate, calcium molybdate, ethylpropanol, orthophenol, sodium edetate, and sodium chloride into the remaining distilled water, stir evenly, and dissolve;

[0040] ④ Mix the liquids obtained in steps ①, ②, and ③, heat to 80°C, stir evenly, and cool;

[0041] ⑤ Mix the liquid obtained in ④ with distilled water in proportion and stir until uniform, and obtain a special grinding fluid for aluminum-based silicon carbide composite materials with a high volume fraction.

[0042] The grinding effect of this experiment is shown in attached table 1, attached figure 1 shown.
