What are the causes of stainless steel hexagon bolt rusting? How to avoid it?
1. The surface of stainless steel hexagon bolt adheres organic juice (such as melon and vegetable, noodle soup, phlegm, etc.) and forms organic acid under the condition of water and oxygen. The corrosion of organic acid on metal surface will rust for a long time. Therefore, it is necessary to avoid organic sweat splashing on it. If it is accidentally splashed, it must be removed in time.
2. In humid air, the attachment and condensed water of stainless steel hexagon bolt connect them to form a micro cell, which causes electrochemical reaction and damages the protective film, which is called electrochemical corrosion. Therefore, it is necessary to keep the stainless steel fastener surface and use environment dry.
3. The adhesion of stainless steel surface contains acid, alkali and salt substances (such as alkali water and lime water splashing on the decoration wall), causing stainless steel hexagon bolt rusting. Therefore, make sure that the bolt surface is clean and tidy.
