Main Applications:
---For the surface treatment of pink molten alumina: metal oxide, carbide black skin, metal or non-metal surface rust removal, such as gravity die casting mold, rubber mold oxidation or free agent removal, ceramic surface black spot, in addition to uranium, paint rebirth.
---Beautification treatment: all kinds of gold, gold ornaments, precious metal products of extinction or fog surface treatment, crystal, glass, corrugated, acrylic and other non-metallic fog surface treatment, can make the surface of processing into metallic luster. ---Used for etching and processing: jade, crystal, agate, semi-precious stones, seals, elegant stone, antiques, marble tombstones, ceramics, wood, bamboo, etc.
---Precision bond grinding tools, such as ultra-thin cutting disc, cutting wheel, grinding wheel.
---Ceramic grinding wheels such as crankshaft grinding wheel, bowl grinding wheel, cup grinding wheel, installation point, ceramic grinding tools, etc.
---Coat grinding tools, such as sandpaper and polishing wheels.
---High quality firebricks.
