Nanometer carbon nanotube doped wet blasting sand material for pump body casting processing

Abstract

The invention discloses a nanometer carbon nanotube doped wet blasting sand material for pump body casting processing, and relates to the technical field of wet blasting processing. The nanometer carbon nanotube 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 carbon nanotube powder, 12-15 parts of river sand, 8-11 parts of alumdum, 6-9 parts of feldspar powder, 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 ethanol and 280-300 parts of water. Bentonite is modified by the carbon nanotube, 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

Technical field:

[0001] The invention relates to the technical field of wet blasting processing, in particular to a wet blasting material for processing pump body castings doped with carbon nanotubes. Background technique:

[0002] 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, so as to obtain 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.

[0003] 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 spraying is...
