Of products of iron line technology rusty with defend

It is metal likewise, some rusts extremely easily, some rusts very hard however. The ironwork that is put in damp place for instance rusts very easily, but the ironwork that is put in dry place is not very easy however rusty; Bare the ironwork in air rusts very easily. Why can you appear this kind of phenomenon? Does iron rust with what the element is concerned after all?
　　
Because be in,the ironware that compares dry place in the ironware of damp place rusts more easily is of damp place the ironware of the place with ironware dry comparing is easier contact with water. What if want,reduce iron is rusty, one of cutting off rusty condition but. Be like an iron above the paint on besmear, cut off iron and airy contact. And put a few metal in dry place, can cut off the contact of iron and water, prevent ironwork to rust thereby.
　　
According to our hypothesis, we devised following tests: Oxygen will be connected in a softer small plastic bottle, and the distilled water with right amount infuse, it is the one part dip of a Tie Ding that is slipped by burnish light in water, one part shows water, cover cup mouth, when waiting for iron to rust if bottle changes,shrivelled criterion and oxygen are concerned, if surface and aerobic boundary are rustily the fastest it is water and oxygen the result of joint action.
　　
Iron rusts not easily in dry air, dip rusts not easily also in the water that isolates with atmosphere, and rust very easily in damp environment. Why?
　　
Because the plasticity of valence electron rate of iron is bigger, chemistry is more lively, so iron has reaction more easily with oxygen. The iron of nature assumes oxidation position commonly, puddling is a ferric oxide actually reductive into iron. Iron can be as acuteness as pure oxygen reaction, iron returns as can slow as the oxygen in humid air ground to undertake oxidizing reacting- - iron is rusty.
　　
In humid air, the rate of the oxygen price in air and movement is higher, constant with the oxygen in lunt transposition, the oxygen rate that just came out from the displacement in lunt is flabby, instantaneous still has odd atomic oxygen to appear, have stronger oxidation performance, meantime, the price of as it happens and iron and rate are consistent, so very easy with iron chemical combination, form 3 oxidation 2 iron. 3 oxidation 2 iron quality of a material is loose suck tide, formed the vicious circle with rusty iron. The carbon dioxide in available still gas has a few can dissolve enters water in, form local carbonic acid, with iron reaction, this also is one of reasons with rusty iron.
　　
The composition of iron is impure, or it is to get outside force and internal stress bigger or be out of shape greater place rusts more easily. Because these external cause can make the price of iron and locomotive rate flabby,this is, when valence and electron change to change or await in movement, the price of foreign material and movement get a change to step in, with iron union formed the oxide of iron.
　　
Stainless steel is actually added in Tie Zhongtian a few chromium or nickel, it is Tie Ge (iron nickel) alloy. Chromium and nickel and iron are same, have 2 price electron, and valence and electronic rate are very stable, mingle between iron, these stable price and movement and steady electric magnetic force, make the rate of the price of the iron all round and movement also subsequently synchronous stability, 2 price of iron and electronic movement were stabilized, have reaction not easily with oxygen, rusted not easily also.
　　
Rusty harm: Create resources waste: Iron and steel rusts is the heel of Achilles of iron, the whole world has every year near very one of because steely goods is rusty and discard as useless, created the enormous waste of resource.
