Problems solved by technology

[0004] At present, the ASJ polishing theory and technology as a non-Newtonian fluid are still very immature. How to overcome the friction and wear defects of the fluid passing through the pipeline, solve the boundary blocking effect between the fluid and the solid wall, and ensure the uniformity and stability of the ejected slurry. Sexuality, economy, and the realization of quantitative and controllable processing are all current technical problems

Abstract

The invention discloses abrasive slurry for abrasive slurry jet processing, prepared from water and an abrasive, wherein the particle size of the abrasive is 0.5 micrometer to 5 micrometers; the abrasive slurry is further prepared from a dispersing agent and a suspending agent, the mass concentration of the dispersing agent is 0% to 8% of that of the abrasive, the dispersing agent is an organic dispersing agent and / or an inorganic dispersing agent, the suspending agent is polyvinyl alcohol, and the mass concentration of the polyvinyl alcohol is 0% to 5% of that of the added abrasive. The abrasive slurry can solve the problem that the agglomeration and precipitation of the abrasive during jet slurry processing result in nozzle plugging and serious system wear, can increase the dispersibility and suspension of the abrasive in the slurry to make the abrasive be uniformly dispersed and not easy to precipitate over time, and can maintain the uniform consistency of slurry jet and high removal ability, so that the abrasive slurry jet processing has a very high polishing effect, meeting the actual production and reducing production cost.

Description

technical field [0001] The invention relates to the technical field of abrasive slurry, in particular to an abrasive slurry for abrasive slurry jet processing and a preparation method thereof. Background technique [0002] In recent years, polishing has a great demand and has been widely used in various industries such as electronic equipment, precision machinery, instrumentation, optical components and medical equipment. Traditional polishing technology is difficult to process special-shaped curved surfaces, slender pipe fittings or workpieces of special materials, and even the polishing of parts in special working conditions cannot be realized. It is especially important to choose a suitable polishing method and polishing process. With the development and use of a large number of difficult-to-machine materials, the existing polishing methods are difficult to meet people's requirements for the surface quality of high-quality and high-performance products. For this reason, m...
