     Surface cleaning: Cleaning must be based on the nature of the rust-proof surface and the conditions of the time, select the appropriate method. Generally used solvent cleaning method, chemical treatment cleaning method and mechanical cleaning method. The surface drying and cleaning can be filtered dry compressed air dry, or with 120~170℃ dryer dry, can also be used clean gauze dry. Immersion method: Some small items are soaked in antirust grease, so that the surface of a layer of rust-proof grease is attached to the method. The thickness of oil film can be achieved by controlling the temperature or viscosity of antirust grease. Brush coating method is not suitable for immersion or spraying of outdoor construction equipment or special-shaped products, brush coating should not only pay attention to the accumulation, but also to prevent leakage of coating.Welding Wire Machine
     Spray method Some large anti-rust materials can not be soaked by immersion, generally with about 0.7MPA pressure filtration Compressed air is sprayed in a clean air place. The spray method is suitable for solvent dilution type antirust oil or thin layer antirust oil, but it must adopt perfect fire protection and labor protection measures. What are the main factors affecting metal corrosion? Metal corrosion is caused by various internal and external factors, mainly include: ① metal material itself chemical composition and structure, ② surface finish (oxygen concentration difference battery corrosion), ③ and metal surface contact with the solution composition and ph value, ④ ambient temperature and humidity, ⑤ and metal surface contact with various environmental media.Welding Wire Machine
     Human sweat is a colorless transparent or light yellow with salty weakly acidic liquid, its ph value is 5 ~ 6. In addition to containing sodium, potassium, calcium, magnesium salt, but also contains a small amount of urea, lactic acid, citric acid and other organic acids. When the sweat and metal contact, the metal surface will form a layer of sweat film, the sweat film will cause electrochemical effect on metals, corrosion metal. People sweating is unavoidable, to prevent hand-sweating caused by rust, production personnel should take gloves, finger sets, or use special tools to take parts, do not casually touch products with hand.Welding Wire Machine
