How do carriage bolts react with different objects? The major role of the carriage bolt is the fixing effect, and it is used in different industries. What will happen to different objects?

1. The attachments of dust or dissimilar metal particles, in the humid air, the attachments and the condensed water of the carriage bolts connect the two into a micro-battery, triggering an electrochemical reaction and destroying the protective film, which is electrochemical corrosion. .

2. The surface of the carriage bolt adheres to the organic juice (such as vegetables, noodle soup, etc.), and in the presence of water and oxygen, it forms an organic acid, which will corrode the metal surface for a long time.

3. The surface of stainless steel adheres to substances containing acids, alkalis and salts (such as alkaline water and lime water splashing from decoration walls), which will cause local corrosion.

4. In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), when encountering condensed water, the formation of sulfuric acid, nitric acid and acetic acid liquid points will cause chemical corrosion.
