Green Silicon Carbide F1500 F2000 for polishing slurry
Green silicon carbide F1500 F2000 are extra fine abrasive powders that have high economic benefits for polishing slurry. Polishing slurry always works in double-sided grinding machines to polish precision parts, mating parts, and optical parts. It achieves the goal of increasing surface smoothness and beautifying products. The double-side grinding works on the base of the relative movement of the workpiece and the grinding tool removes burrs and edges on the surface of the workpiece. The abrasive in the grinding fluid plays a role in improving polishing speed and smoothness.
Green silicon carbide powder is suitable for hard and brittle materials such as optical glass, optical ceramics, hard alloys, and chromium-containing alloys. Grits of green silicon carbide ultrafine powders F1500,F2000 are commonly used specifications. GC micro powder has the following advantages as a polishing slurry abrasive:
1. Good liquidity.
Green silicon carbide F1500, and F2000 correspond to 8000#,10000#. They are produced through acid-alkali washing and overflow processes and have good fluidity. Therefore, the fine particles generated during the grinding process of green silicon carbide micropowder will not block the micropores of the grinding tool. That is beneficial for improving the chip removal performance, grinding efficiency, and grinding time of the grinding fluid.
2. Uniform particle size.
The particle size of green silicon carbide micro powder should be within a certain micrometer range. Therefore, it can avoid scratches caused by large particles on the workpiece. In the meantime, it prevents small particles from not being able to act on the grinding, forming small debris and affecting the grinding efficiency. Silicon carbide micro powder with uniform particle size can improve the fineness and smoothness of grinding.
3. High hardness and mechanical strength.
The microhardness of green silicon carbide is 3100-3400kg/mm2, which is used for hard alloy milling cutters, optical glass components, and optical ceramic components, and has strong grinding ability. At the same time, green silicon carbide has high mechanical strength, with a single particle compressive strength of 186KN/cm2, strong anti-crushing ability, and can withstand the pressure and impact force during grinding and extrusion.
4. High toughness and self-sharpness.
Green silicon carbide has a ball milling toughness of about 70% and high self-sharpness. During the grinding process, abrasive particles can continuously generate new cutting edges, quickly removing uneven protrusions and edges on the surface of the workpiece.
5. Good chemical stability.
Green silicon carbide ultrafine powders F1500 F2000 have chemical inertness and can resist the erosion of chemicals such as acid and alkali. Therefore, it will not react with suspensions, oily liquids, grinding workpieces, and grinding tools in the grinding fluid.
6. Thermal stability and thermal conductivity.
Green silicon carbide micro powder will not melt under any known grinding pressure conditions. In addition, green silicon carbide also has physical properties such as high thermal conductivity and low coefficient of thermal expansion, which keep its physical and chemical properties stable in the high-temperature grinding area.
7. High Cleanliness.
Green silicon carbide ultrafine powder is a suspension-treated powder with purified water after acid and alkali treatment. The free components and carbon residue in the powder are small, and the cleanliness is high. The washed silicon carbide micro powder can maintain a neutral pH value without affecting the performance of other modified materials and dispersants.
Moreover, green silicon carbide itself has hydrophilic and oleophobic properties. The current mainstream polishing slurry is oil-based grinding fluids with modification treatment. The processed oily grinding fluid is more suitable for fields such as semiconductors and electronics.
