Stainless steel screws are common fasteners in daily life, rust is a common phenomenon in the course of use, but also make us worry, it will not only affect the aesthetic level, but also affect the use of stainless steel screws performance. Therefore, we must pay attention to the use of the main points while us the process of stainless steel screws.
1) Dust or dissimilar metal particles attachments, in the humid air, the attachment and the stainless steel screw condensate, the two together into a micro-cell, causing the electrochemical reaction, the protective film damages, called the electricity Chemical corrosion.
2) Stainless steel screw surface adhesion organic juice (such as vegetables , noodle soup, sputum, etc.), in the case of water oxygen, constituting organic acids, organic acids for a long time on the metal damaging surface.
3) Stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration of the wall of alkaline water, lime water splash) also cause local eclipse.
4) In the polluted air (such as containing large amounts of sulfide, carbon dioxide, nitrogen oxide atmosphere), the case of condensation, the formation of sulfuric acid, nitric acid, acetic acid liquid point, cause chemical corrosion.
