Antirust measures of screw diz fastener

发布日期:2019-09-26

  We all know the role of bolts, screws and other fasteners in daily life that rust will occur in use, which is a headache for us. Once rusted, it will not only affect the appearance, but also affect its performance, which has a great impact on the use of equipment. Therefore, we should pay attention to the following situations in use to prevent rust.

  1. In humid air, the attachment of dust or dissimilar metal particles and the condensate of stainless steel screws form a micro battery, which leads to electrochemical reaction and damages the protective film, which is called electrochemical corrosion.

  2. The surface of stainless steel screw adheres to organic matter juice, which forms organic acid in the presence of water and oxygen. For a long time, the organic acid corrodes the metal surface.

  3. The surface of stainless steel is rich in acid, alkali and salt, which causes local corrosion.

  4. In the polluted air (such as the atmosphere rich in sulfide, carbon oxide and nitrogen oxide), when encountering condensed water, it forms the liquid point of sulfuric acid, nitric acid and acetic acid, causing chemical corrosion.

  In use, we should avoid these situations, check and maintain these parts regularly, and reduce the corrosion of parts, which is also of great help to the production and development of enterprises.
