Description

A kind of carbon steel support corrosion resistant handling process
Technical field
The present invention relates to air conditioner support manufacturing field, specifically a kind of carbon steel support corrosion resistant handling process.
Background technology
With the high speed development of modern society, scientific and technological progress brings huge facility for the life of people, such as in inflammation In the summer of heat, air-conditioning starts to turn into townie indispensable product, but in most old-fashioned floor and is not designed with special Outdoor machine of air-conditioner platform for placing, therefore, most outdoor machine of air-conditioner are all by the way that machine support is followed closely on wall outside triangle made from metal Installed.And the outer machine support of these triangles will produce substantial amounts of rusty stain after use in 5 to eight years, structure is no longer stable, So as to cause potential safety hazard.
The content of the invention
The present invention is intended to provide a kind of carbon steel support corrosion resistant handling process, improves the rustless property of support, extends product Service life.
To achieve the above object, technical scheme is as follows：
A kind of carbon steel support corrosion resistant handling process, it is characterised in that comprise the following steps：
Sorting：From carbon sheet as blank；
Heat treatment：The steel plate of selection is made annealing treatment, 650-720 DEG C of keeping temperature, 15 minutes duration, be air-cooled to room Temperature；Then steel plate is subjected to compacting by rolling, draws support crude green body, cooled down rapidly after removing oxide skin；
Machining；Support crude green body is finished, obtains the complete profile of support；
Oxygenerating layer：Manufactured support is put into acid solution, immersion is kept for more than 30 minutes, is finally taken out and is rinsed；
Surface treatment：To oxidation layer surface jet flames and simultaneously in flame add molten condition alloy particle formed it is wear-resisting Layer, alloy particle is tungsten-cobalt alloy particle；
Antirust is surface-treated：In wear-resistant alloy layer surface spraying or roller coating corrosion resistant paint, the corrosion resistant paint is by acrylate group 30 parts of compound, 20 parts of epoxy resin, 20 parts of epoxy acrylate, 10 parts of silicone coupling agents, 10 parts of methyl silanol potassium, coating are molten 40 parts of agent is mixed in mass ratio；And in anti-corrosion paint surface spraying polyurethane lacquer three times.
Further, the paint solvent is the mixture of dimethylbenzene and methyl iso-butyl ketone (MIBK).
The beneficial effects of the present invention are：Using 304 stainless steels, can effectively anticorrosive oxidation, avoid support in specific ring The problem of service life shortens in border, employs acid solution and is cleaned, and the iron filings on top layer of going out simultaneously form oxide layer and effectively protected Protect rest body.And antirust coat is made in oxidation layer surface, effectively increase the service life.
Embodiment
With reference to specific embodiment, the present invention will be further described.
A kind of carbon steel support corrosion resistant handling process, it is characterised in that comprise the following steps：
