Embodiment 1
[0033] A kind of abrasive slurry that is used for abrasive slurry jet processing of the present embodiment, comprises water and abrasive material, and described abrasive grain diameter is 0.5 micron, and described abrasive slurry also comprises dispersant, and the mass concentration of described dispersant 0% to 5%, the dispersant is organic dispersant and / or inorganic dispersant, further, the model of the dispersant is SAM1112 dispersant, SAM dispersant is mainly used for grinding and dispersing various inorganic materials in water , the general dosage during wet grinding is 0.1% to 0.2% of the dry powder, the abrasive concentration is 50 to 70%, and can reach below 5 microns. If a finer particle size is required, the abrasive concentration can be appropriately reduced and the dispersant concentration can be increased. It is used for polishing processing of brittle and plastic materials, further, the brittle and plastic materials are die steel.
