The element with rusty stainless steel

The ability that stainless steel has mutinous air to oxidize does not become rusty namely quality, in also having the medium that containing acerbity, alkaline, salt together anticorrosive ability namely corrosion resistance. But its fight the large and small that corrodes ability is composition of chemistry of therewith steel qualitative oneself, each other state, use condition reachs environmental medium kind and alter. Be like 304 data, be in as dry as a chip in the air that clean, have fight outstandingly absolutely corrode ability, but move it seaside area, in the sea fog that contains a lot ofa lot of salinity, can rust very quickly. Consequently, not be a kind of any stainless steel, in any moment can anti-corrosive, rustless.
Stainless steel is to rely on its appearance to form a paper-thin and film of solid and close smooth and steady Fu Ge oxidation (defend film) , avoid oxygen atom to last infiltration, oxidize continuously, and obtain fight cankerous ability. One but have some kind of essential factor, this kind of film suffers ceaseless damage, air or liquid counteract oxygen atom to be met the iron in ceaseless infiltration or metal is atomic ceaselessly analyse leaves come out, form loose ferric oxide, metallic appearance also suffers ceaseless rustily. The kind that this kind of outside film damages is very much, in living at ordinary times, see more have a few kinds as follows:
1, the dust that stainless steel appearance collects store up to contain a lot ofother tantalum or alien metal the attachment of makings, in humid air, the condenser water between attachment and stainless steel, become both a small cell repeatedly, caused electrochemistry echo, diaphragm suffers damage, say call electrochemistry is corroded.
2, stainless steel appearance sticks juice of adherent and organic matter (if melon dish, water in which noodles have been boiled is phlegmy,wait) , below state of oxygen having water, make organic acid, form organic acid for a long time to be opposite the metal is corroded outsidely.
3, conglutinate of stainless steel appearance contains a lot ofacerbity, alkaline, salt kind material (if decorate the buck of wall, limewater gush,measure) bring about a part to corrode.
4, in the air that has pollution (the air that contains a lot ofhydrogen of a lot of sulfide, oxide, oxidation) , treat condenser water,
Make point of fluid of nitric acid, acetic acid, bring about chemistry to corrode.
Above state all can form stainless steel appearance to defend velar attaint, bring about corrode. So, belong to outside and abiding light for bail, be not rusted, we advocate:
① is necessary to often undertake cleaning wiping to decorating stainless steel appearance, take out attachment, eliminate cause rustily outside element.

6, one but does stainless steel present rusty spot how should handle? A) chemical method:
Cream with pickling or sparge assists his rustily place from the beginning passivation forms oxidation chromic film to make its recover from the beginning anti-corrosive ability, after pickling, for take out all contaminant is mixed acerbity hangover, it is very important to undertake be rinsinged appropriately with clear water. Polishing device is used after everything is handled from the beginning polishing, use polishing dried meat to shut can. What have subtle rusty spot to the part is usable also 1: Mixed liquor of the benzine of 1, engine oil obliterates with clean dishcloth rusty spot can. B) mechanical method:
Gush is arenaceous arrange, with glass or particle of pottery and porcelain gush bolus is arranged, annihilation, rinse and polishing. Have with mechanical method but
The pollution that the data that can obliterate to be eradicated before, polishing data or annihilation data form. Everything all sorts of pollution especially grain of ab extra iron becomes cankerous source possibly, it is especially in wet environment. Consequently, machinery arranges appearance optimal the standard ought to make arrange below as dry as a chip condition. Use rigid standard to be able to arrange its appearance only, cannot alter of data oneself fight corrode ability. Consequently the view uses polishing device after machinery is arranged from the beginning polishing, use polishing dried meat to shut
