1) surface cleaning: cleaning must depend on the nature of the surface is antirust things at that time and conditions, select the appropriate methods. General commonly used a solvent method, chemical cleaning dealing with cleaning method and mechanical cleaning method.

2) surface dry clean available dry after filtering compressed air blow dry, or use 120 ~ 170 ℃ dryer drying, also can use clean dry gauze.

Apply the method of temporary

1) soaking method: some small items by soaking in the rust of oil, make its surface adhesion on a layer of rust the method of grease. Oil film thickness can control the temperature of the rust or viscosity oil to achieve.

2) brush besmear of soaking or spraying shall not apply for the outdoor construction equipment or special shape of products, brush besmear is to pay attention to when do not produce accumulation, also want to pay attention to prevent leakage coating.

3) spray method and some big things can't rust by soaking method with oil, general use of about 0.7 Mpa pressure filtration of compressed air in the air clean place spraying. Spray method XiShiXing solvent for temporary or temporary thin layer, but must use perfect fire prevention and labor protection measures.

The main factors affect metal corrosion have?

Metal corrosion is by all sorts of internal and external factors have cause, to sum up the main are:

(1) metal material itself chemical composition and structure;

(2) the metal surface finish (oxygen concentration poor battery corrosion);

(3) and metal surface contact solution composition and pH value;

(4) the environment temperature and humidity;

(5) metal surface in contact with all sorts of environmental medium.

Why hand sweat can cause metal corrosion?

People of sweat is a colorless transparent or light yellow with a weak acid salty liquid, it pH value for 5 ~ 6. In addition to containing sodium, potassium, calcium, magnesium salt outside, also contain a small amount urea, lactic acid, citric acid, organic acids. When the sweat and metal contact, will be in the metal surface to form a layer of sweat membrane, sweat film will cause of metal electrochemical role, corrosion of metal. People sweat is inevitable, to prevent sweat corrosion caused by hand, production personnel should bring gloves, gloves, or use a special tool to take part, don't literally hand contact products.
