Classification and application of abrasive paste:
Abrasive is a mixture of abrasive, dispersant (also known as lapping liquid) and auxiliary materials, and is used as a kind of abrasive. The abrasive is used for grinding and polishing, and the abrasive grain is free when used. As the composition and proportion of dispersants and auxiliary materials are different, the grinding agent is liquid, paste and solid.
The abrasive has a cutting function, and the commonly used abrasive is corundum, silicon carbide, boron carbide and synthetic diamond. Soft abrasive materials such as iron oxide, chromium oxide and cerium oxide are also used in the finishing and polishing.
Dispersants are used to disperse abrasive and disperse the abrasive, and to dilute, lubricate and cool, etc., commonly used in kerosene, oil, animal oil, glycerin, alcohol and water. Auxiliary materials mainly mixed fat, often by stearic acid, fatty acid, ethylene oxide, paraffin wax, oleic acid and triethanolamine, cetyl alcohol made up of several kinds of materials, such as in the process of grinding, emulsifying, lubrication and adsorption and prompted the workpiece surface chemical changes, easy loss of oxidation film or sulfide film, so as to improve the machining efficiency. In addition, there are colorants, preservatives and fragrances in the auxiliary materials.
Grease-mixed mainly employed in the manufacturing of high-hardness materials for instance burden machine grinding, polishing sintered-carbide, alloyed steel, high carbon steel etc.
Water-mixed mainly employed in the finish lapping of the samples of metallic phase & lithofacies etc.
This article will focus on Superhard Materials abrasive paste.
Superhard Materials Abrasive-paste is produced fine and confect by the diamond/CBN micrones and other raw-materials, it is a relevant ideal Abrasive-paste for grinding and polishing with well lubrication and cooling capability, the hardness of diamond granule is high with equal granularity, and excellent grinding effects. They are kinds of soft abrasives. It is used for grinding hard brittle materials to obtain a high surface finish. With the Diamond or CBN crystal as raw material, adopts the most advanced powder preparation separation technology extremely narrow diamond and CBN powder size distribution, strict controlled nano and micron crystal control system, let every single particle approximate round values are almost perfect, successful participation in grinding and polishing process, get more high quality reproducibility.
CBN Abrasive Paste is produced fine by its micrones and other raw-materials, it is a relevant ideal Abrasive-paste for grinding and polishing with well lubrication and cooling capability, the hardness of CBN granule is high with equal granularity, and excellent grinding effects.
This kind of Lapping Paste with Superhard materials powder and other chemical compound mixing, has good grinding performance, no corrosion, good lubrication and cooling, improving efficiency and workpiece is bright and clean degree, smoothness, is ideal for high precision grinding agent. materials, glass, ceramics, hard alloy, natural diamonds, precious stones and other measuring tools, cutting tools, optical instruments and other high finish of workpiece processing.
