1) Surface cleanliness: Cleaning must be based on the nature of the surface of the antirust object and the conditions at that time, and an appropriate method must be selected. Commonly used are solvent cleaning method, chemical disposal cleaning method and mechanical cleaning method. 2) After the surface is dry and cleaned, it can be dried with filtered dry compressed air, or dried with a dryer at 120~170 °C, or dried with clean gauze. Method of applying anti-rust oil 1) Immersion method: A few small items are immersed in anti-rust grease, and a layer of anti-rust grease is adhered to the surface. Oil film thickness can be achieved by controlling the temperature or viscosity of the anti-rust grease. 2) The brushing method is used for outdoor equipment or special-shaped products that are not suitable for immersion or spraying. When brushing, attention should be paid not only to avoid accumulation, but also to prevent leakage. 3) Spraying method A small amount of large-scale rust preventives cannot be oiled by immersion method. Generally, spraying is carried out in a clean air place with filtered compressed air with a pressure of about 0.7Mpa. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but perfect fire protection and labor protection measures must be adopted. What are the main factors affecting metal corrosion? Metal corrosion is caused by various internal and external factors, which can be summarized as follows: ① The chemical composition and structure of the metal material itself; the imported bearing network columns include: bearing application, bearing model inquiry, bearing model, bearing type, Imported bearings, bearing model Daquan, bearing common sense. ②Metal surface finish (corrosion of battery due to oxygen concentration difference); ③Solution composition and pH value in contact with metal surface; Common types of China Bearing Network: slewing bearing, full complement roller bearing, spherical bearing with seat, rolling mill bearing, thrust roller Sub bearings, spherical plain bearings, linear motion bearings, thrust ball bearings, one-way bearings. ④ Ambient temperature and humidity; ⑤ Various environmental media in contact with metal surfaces. Why does hand sweat cause metal corrosion? Human sweat is a colorless, transparent or slightly acidic liquid with a salty taste, and its pH value is 5-6. In addition to sodium, potassium, calcium, and magnesium salts, it also contains a small amount of organic acids such as urea, lactic acid, and citric acid. When sweat comes into contact with metal, a sweat film will be formed on the metal surface, and the sweat film will cause electrochemical action on the metal and corrode the metal. Human sweating is unavoidable. To prevent hand sweat from causing rust, production personnel should wear gloves, finger cots, or use special tools to pick up parts, and do not touch the product with hands.
