(2) The surface is dry and cleaned and can be dried by filtered dry compressed air; perhaps dried with a drier of 120~170 °C; it can also be dried with a clean gauze.
Method of applying anti-rust oil:
(1) Soaking method: some small items should be soaked in anti-rust grease; let the outer surface adhere to a layer of anti-rust grease. The thickness of the oil film can be reached by controlling the temperature or viscosity of the anti-rust grease.
(2) Brushing method is used for outdoor construction equipment or special shaped products that are not suitable for soaking or spraying; when painting, it is necessary to pay attention to not accumulating; also pay attention to avoid leakage coating.
.3) Spray method Some large-scale rust-proof materials cannot be immersed in oil; usually, the compressed air is sprayed at a pressure of about 0.77 MPa in the air. The spray method is suitable for solvent-diluted rust-proof oil or thin-layer rust-proof oil. However, it is necessary to choose a sound fire and labor insurance method.
What are the main factors affecting metal corrosion?
Metal corrosion is caused by various connotations and external factors; the main ones are:
1The chemical composition and layout of the metal material itself,
2 metal appearance finish (oxygen concentration difference battery corrosion),
3 with the composition of the metal touch and the pH value,
4 ambient temperature and humidity,
5 various environmental media touched by the metal appearance.
Why does hand sweat cause metal corrosion?
Human sweat is a colorless, bright or light yellow liquid with a salty taste and weak acidity; its pH is 5-6. In addition to being rich in sodium, potassium, calcium and magnesium salts; it is also rich in a small amount of urea. Organic acids such as lactic acid and citric acid. When sweat and metal touch; it will form a layer of sweat film on the metal surface; the sweat film will cause electrochemical effects on the metal; corrosion metal.
People sweating is inevitable; to avoid rust caused by sweat; production personnel should wear gloves, finger cots; or take special parts with tools; do not touch the product with your hands.
