Abstract

The invention discloses a wet-spraying sand material doped with carbon nanofibres and used for pump body casting processing, and relates to the technical field of wet-spraying processing. The wet-spraying sand material is composed of, by mass, 90-100 parts of quartz sand, 15-20 parts of bentonite, 5-8 parts of carbon nanofibres, 12-15 parts of river sand, 10-13 parts of sea-foam stone powder, 6-9 parts of alumdum, 5-8 parts of putty powder, 3-5 parts of cement, 1-2 parts of tallow amine, 0.5-1 part of zinc carbonate, 25-30 parts of ethyl alcohol and 280-300 parts of water. According to the wet-spraying sand material, the carbon nanofibres are used for modifying the bentonite, and thus the overall performance of the sand material can be better improved; the obtained sand material can be used for wet-spraying treatment of pump body castings directly, hence, the roughness of the surfaces of the castings is lowered, oxide skin, rust, oil stains and other impurities on the surfaces of the castings are removed, and subsequent coating spraying and pump assembling are facilitated.

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-carbon fibers. [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;...
