Abstract

The invention discloses a kind of rust-proofing methods of derusting by sandblasting, its key points of the technical solution are that adding a certain proportion of cement pulvis in the abrasive material of derusting by sandblasting, cement pulvis is sprayed to metal surface by the pressure-air or high pressure water of abrasive blast equipment, the cement pulvis of extra or attachment loosely is cleared up using the impact of abrasive material and pressure-air or high pressure water, keep the attached layer of cement pulvis very thin, prevents the flowing of metal surface electronics to achieve the purpose that antirust using the passivation of cement pulvis.At low cost, easy to operate, favorable rust preventing effect has good application prospect.

Description

The rust-proofing method of derusting by sandblasting
Technical field
The present invention relates to the rust-proofing methods of rust-proofing method more particularly to derusting by sandblasting after derusting.
Background technology
Derusting by sandblasting is the pressure-air that air compressor machine is generated, by air accumulator and sandpipe abrasive material finally in sand-blasting gun rifle Head height speed sprays, and derusting stain is gone using the impact, friction and shear action of high-speed motion abrasive material.The method of this derusting by sandblasting Effect is good, efficient, has been commonly applied to each derusting place.But metal surface by high-speed motion abrasive material impact, rub After wiping and cutting, surface-active is very high, and too early application can get rusty because of metal surface activity high yield loses and then make coating shedding；It crosses Late application can cause metal surface corrosion, to influence coating adhesion.Addition can have a material spraying in the skill to derust Art surface can reduce the activity of metal surface, can improve coating adhesion and prevent the corrosion of technical face under coating, To extend the protection period of coating.
Cement category alkaline matter, being coated in metal surface has passivation, and the electronics of metal surface can be prevented to flow, to Anti-rust action can be played.
Invention content
Present invention solves the technical problem that being exactly the antirust problem after derusting by sandblasting, by adding certain proportion in abrasive material Cement pulvis, up to antirust purpose is played, feature includes the following steps：
（1）A certain proportion of cement pulvis is added in the abrasive material of derusting by sandblasting, and stirs evenly；
（2）Cement pulvis is sprayed to the metal surface after derusting by sandblasting by the pressure-air or high pressure water of abrasive blast equipment；
（3）The cement pulvis of extra or attachment loosely is cleared up using the impact of abrasive material and pressure-air or high pressure water, makes cement powder The attached layer of agent is very thin；
（4）The flowing that passivation prevents metal surface electronics is obtained using cement pulvis, achievees the purpose that antirust；
Further, the step（1）In cement pulvis can also be other kinds of corrosion inhibitor；
Further, the step（2）In abrasive blast equipment may be other high pressure painting equipment；
The apparent effect of the present invention is：After adding a certain proportion of cement pulvis in the abrasive material of derusting by sandblasting, derusting by sandblasting Antirust period from a few houres extend to more than 30 days and do not have corrosion, keep metal surface activity very low, have both ensured the attached of coating Put forth effort, and the effective protection period for extending coating, at low cost, easy to operate, favorable rust preventing effect.
