Recently, diamond slurry has been successfully developed in the Yellow River cyclone, and new members have been added to the cyclone abrasive series.

The diamond slurry is another type of "abrasive tool" different from the fixed abrasive and the coated abrasive. The diamond powder is used as an abrasive, and is dispersed into a solvent by adding a dispersing agent or the like to form a liquid having a grinding action. The diamond powder is free in the solvent, and the high hardness is used to achieve grinding and thinning of the workpiece. There are two classification methods: one is classified into single crystal diamond slurry, polycrystalline diamond slurry and nano diamond slurry according to the type of diamond powder; the other is classified into water-based, oil-based and general-purpose according to solvent type. Kind. Among them, the single crystal diamond polishing liquid has the advantages of high cutting force and low processing cost; the polycrystalline diamond polishing liquid has the advantages of high grinding force and is not easy to scratch the workpiece; and the nano diamond polishing liquid can form a high quality processing surface.

Slurry

At present, the developed slurry is a water-soluble diamond slurry, which is made of yellow river cyclone single crystal diamond powder and specially treated polycrystalline diamond powder, and uses safe and environmentally friendly reagents as solvent. Stable raw materials, high purity, high precision and good crystal form. The single crystal powder has high hardness and high grinding removal rate; the polycrystalline powder has a large number of cutting edges, which ensures the grinding efficiency and has good self-sharpness and is not easy to scratch the workpiece. With excellent abrasive and high-efficiency solvent, the product has the characteristics of good suspension, easy cleaning, non-contamination, fast grinding speed and cooling effect. Mainly used in the grinding and polishing of various hard materials such as LED sapphire substrate, silicon carbide wafer, optical crystal, ceramic, super hard alloy.

Polycrystalline diamond powder

Providing customers with quality products and services is the unremitting pursuit of the Yellow River whirlwind. In the later stage, new products such as oily diamond slurry, single crystal nano-diamond powder and nano-diamond slurry will also be available.
