Abstract

The invention discloses a nanometer meerschaum doped wet blasting sand material for pump body casting processing, and relates to the technical field of wet blasting processing. The nanometer meerschaum doped wet blasting sand material is prepared from, by weight, 90-100 parts of quartz sand, 15-20 parts of bentonite, 5-8 parts of nanometer meerschaum powder, 12-15 parts of river sand, 7-10 parts of feldspar powder, 5-8 parts of alumdum, 3-5 parts of cement, 1-2 parts of aminohexadecane, 0.5-1 part of water glass, 0.2-0.5 parts of zinc carbonate, 25-30 parts of ethanol and 280-300 parts of water. Bentonite is modified by the nanometer meerschaum, so improvement of comprehensive performances of the sand material is benefited; and the prepared sand material can be directly used in wet blasting treatment of a pump body casting, so the roughness of the casting surface is reduced, scales, rusts, oil stains and other impurities on the surface are removed, and subsequent coating spraying and pump assembling are benefited.

Description

[0001] Technical field: [0002] The invention relates to the technical field of wet spraying processing, in particular to a wet sandblasting material for processing pump body castings doped with nano sepiolite. [0003] Background technique: [0004] Sandblasting is one of the best quality surface pretreatment methods. It can not only completely remove oxide skin, rust, old paint film, oil stains and other impurities on the metal surface, so that the metal surface shows a uniform metal color; but also can make the metal surface obtain a certain roughness to obtain a uniform roughness Surface, and change the machining stress into compressive stress, improve the bonding force between the anti-corrosion layer and the base metal and the corrosion resistance of the metal itself. [0005] Sandblasting is divided into two types: dry spraying and wet spraying. Dry spraying has high efficiency, but the processed surface is rough, the dust is large, and the abrasive is broken more; wet...
