Several methods of anti - rust of non - standard bearing
1) Surface cleaning: Appropriate cleaning process should be selected according to the surface characteristics and environmental conditions of the rust-proof object. Usually using solvent cleaning, chemical cleaning, mechanical cleaning and other methods.
2) After drying and cleaning, the surface can be dried with filtered dry compressed air, or dried with a dryer of 120~170℃, or dried with clean gauze.
Method of applying antirust oil
1) Soaking method: Some small items are soaked in anti-rust grease, so that the surface adhesion on a layer of anti-rust grease method. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the antirust grease.
2) Brush coating method is used for outdoor construction equipment or special shape products that are not suitable for soaking or spraying. It is necessary to pay attention not to produce accumulation when brushing, but also to prevent leakage coating.
3) Spray method Some large rust prevention materials can not be coated by soaking method. Generally, filtered compressed air at about 0.7Mpa pressure is used for spraying in clean air places. Spray method is suitable for solvent dilution type anticorrosive oil or thin layer anticorrosive oil, but must adopt perfect fire protection and labor protection measures.
