example 1

[0022] According to the mass ratio of 1:2, put the chicken heart and raw egg yolk into a tissue grinder and grind for 1 hour to obtain a mixed grind, put the mixed grind in a greenhouse with a temperature of 35°C and a relative air humidity of 70%, and let it stand The moldy mixture was treated for 3 days to obtain the moldy mixture; the moldy mixture and water were mixed and stirred at a mass ratio of 1:5 for 15 minutes and transferred to a fermenter, sealed at the mouth of the tank, and fermented at 25°C for 8 days. After the fermentation was completed, it was filtered to obtain the fermented Liquid, centrifuged at 3000r / min for 10min with a centrifuge, separated to obtain the supernatant, and then concentrated by rotary evaporation at 70°C for 20min with a rotary evaporator to obtain a concentrated solution; weigh diatomaceous earth and put it in a pulverizer to pulverize Pass through a 200-mesh sieve, mix and stir the sieved powder, water and cationic polyacrylamide at a ma...

[0024]According to the mass ratio of 1:2, put the chicken heart and raw egg yolk into a tissue grinder and grind for 2 hours to obtain a mixed grind, put the mixed grind in a greenhouse with a temperature of 40°C and a relative air humidity of 75%, and let it stand The moldy mixture was treated for 4 days to obtain the moldy mixture; the moldy mixture and water were mixed and stirred at a mass ratio of 1:5 for 18 minutes and transferred to a fermenter, sealed at the mouth of the tank, and fermented at 30°C for 9 days. After the fermentation was completed, it was filtered to obtain a fermented Liquid, centrifuged at 3300r / min for 13min with a centrifuge, separated to obtain the supernatant, and then concentrated by rotary evaporation at 75°C for 25min with a rotary evaporator to obtain a concentrated solution; weighed diatomaceous earth and put it into a pulverizer for pulverization Pass through a 200-mesh sieve, mix and stir the sieved powder, water and cationic polyacrylamide ...

Abstract

The invention relates to the technical field of polishing agent preparation, in particular to a method for preparing a liquid metal polishing agent. After the liquid polishing agent prepared by the present invention is used, the concentrated solution rich in nitrogen, phosphorus and sulfur will produce a layer of chemical extreme pressure film on the surface of the metal substrate to prevent the mutual abrasion between the metal substrates to produce large polishing scratches, while the fatty alcohol The compound can stabilize the foam, increase the consistency of the liquid polishing agent, and produce a viscous effect on the metal surface. The viscous liquid and the nitrogen, phosphorus, and sulfur extreme pressure film together provide a protective film for the metal surface to buffer the polishing process. Mutual friction produces large wear marks, and the protective film produced by viscous action is not static, but the dynamic balance in motion, the sliding friction produced by the sliding between the viscous liquid and the surface of the metal substrate, this friction is more uniform , more detailed, so it can achieve lower roughness, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of polishing agent preparation, in particular to a method for preparing a liquid metal polishing agent. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is a modification process on the surface of the workpiece by using flexible polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror luster, and is sometimes used to eliminate gloss extinction. [0003] At present, the research on surface polishing aids for metal materials has been developed by leaps and bounds. With the continuous update of products, the requirements for such metal surface polishing aids are getting higher and higher. It not only has the...
