The use of stainless steel with economic development become more extensive, people in daily life and stainless steel is closely related, but a lot of people on the performance of stainless steel is not much, the maintenance of stainless steel to know a little more. A lot of people think that stainless steel is never rust, in fact, the corrosion resistance of stainless steel is good, the reason is the formation of a layer of surface film, in nature, it is the existence of a more stable oxide. That is, although the use of stainless steel in different conditions, the oxidation degree is not the same, but the final oxidation, this phenomenon is usually called corrosion.
Exposed in the corrosive environment of all metal surface chemical reaction or chemical reaction, uniform corrosion, stainless steel surface purification film corrosion resistance ability of the site, due to the self excited reaction and the formation of pitting, the formation of small holes, and the formation of a strong corrosive solution, accelerated corrosion rate. There is also the intergranular corrosion cracking of stainless steel, all of these, the surface of the stainless steel surface of the purification of the film are destructive.
Therefore, the stainless steel surface must be carried out regularly cleaning and maintenance, in order to maintain its surface and extend its service life. Cleaning stainless steel surface must pay attention to the phenomenon that does not have the surface scratches, avoids using the bleaching ingredient as well as the abrasive fluid, the steel wire ball.
1, stainless steel surface dust and easy to get rid of dirt can be used to wash the weak detergent, binder composition, use alcohol or organic solvent (ether, benzene) scrub.
2, the surface of the stainless steel oil, oil pollution, use a soft cloth to wipe clean, use a neutral detergent or ammonia solution or with special detergent.
3, stainless steel surface with bleach and various acids attached, immediately wash with water, and then ammonia solution or neutral carbonated soda solution immersion, use neutral detergent or washing in warm water.
4, the surface of stainless steel has a rainbow pattern, is too much use of detergent or oil, washing with warm water neutral detergent can wash away.
5, stainless steel surface dirt caused by rust, can be used to wash the 10% nitric acid or abrasive, but also can be used to wash the special wash.
As long as we use the correct maintenance method, we can extend the service life of stainless steel.
