Problems solved by technology

The existing grinding agent in the domestic and foreign markets is the product of American Flux, and its zirconia grinding liquid is made of zirconia powder (D 50 : 1.15-1.60 μm, D 100 <5.60μm) is dispersed in the water phase, adding auxiliary materials and colorants, such as alcohols and esters, to emulsify, lubricate and absorb. Although the grinding effect of this product is good, but due to the The particle size and shape requirements of zirconia powder raw materials are relatively high, so its production cost is high and expensive

Abstract

The invention discloses production technology of zirconia grinding fluid, relating to the new material processing field. The production technology is as follows: adding zirconia powder into high-speed dispersing water according to the weight share, then adding wetting dispersants, grinding aids, mixed lipids and alcohols, after full dispersion, sending the materials to a high-speed sand grinder for sand grinding, grinding the corners of the zirconia powder to round spheres and then adding coloring agents to adjust the colors. The production technology is characterized in that the production technology is free from the influences of the grain sizes and shapes of the zirconia raw materials and has lower production cost. The product can be used for grinding and polishing lenses, plate glass,glass bulbs, glasses, watch cases, display screens and the like, and is especially suitable for grinding and polishing the spherical glass made of soft materials.

Description

technical field [0001] The invention relates to the field of new material processing, in particular to a production process of zirconia grinding fluid. Background technique [0002] Abrasive liquid is a mixture of abrasives, dispersants and auxiliary materials. It is used for grinding and polishing lenses, flat glass, glass shells, glasses, watch cases, display screens, etc. The abrasives play a cutting role. The commonly used abrasives are corundum , SiC, iron oxide, zirconia, cerium oxide, etc., zirconia is a soft abrasive, mainly used for grinding and polishing soft spherical glass. The existing grinding agent in the domestic and foreign markets is the product of American Flux, and its zirconia grinding liquid is made of zirconia powder (D 50 : 1.15-1.60 μm, D 100 <5.60μm) is dispersed in the water phase, adding auxiliary materials and colorants, such as alcohols and esters, to emulsify, lubricate and absorb. Although the grinding effect of this product is good, but ...
