We buy stainless steel door because we know that it is made of stainless steel, and it is a special door that can resist rust stain. Is stainless steel door really not rusty? In fact, if people who think so are wrong, because stainless steel doors are only rust resistant and not easy to rust. If it is difficult to avoid rusting under specific circumstances and for a long time, then what are the causes of stainless steel doors rusting?
Reasons for stainless steel door rusting:
1. The stainless steel door is exposed to the air for a long time, so the surface is easy to be stained with dust and other different organic matters on the surface. And because it is easy to have oxidation and acid corrosion under special circumstances, it will cause long-term corrosion on the surface of stainless steel door, thus forming some rust stains that we can see with naked eyes.
2. Many stainless steel door factories will add some acid and alkali into the raw materials when making stainless steel doors, so this also leads to the existence of acid-base substances on the surface of stainless steel doors, and if there is long-term corrosion, there will also be mottled corrosion.
3. In addition to acid and alkali, the surface of stainless steel door is also rich in other metal elements. If it is used in the air environment of Chaoshan, a series of metal chemical changes will also occur, which will damage the film on the surface of stainless steel door and cause corrosion.
4. If rain drops and other trace sulfuric acid, nitric acid, etc. touch the surface of stainless steel door, it will also affect the appearance expansion of stainless steel door and mottle.
To sum up, the causes and effects of stainless steel door rust are determined by many factors. We can not completely avoid the occurrence of this chemical change, but we can know the reason as much as possible, and then deliberately avoid and maintain it.
