During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acids, alkalis, salts and carbides in the ambient atmosphere, physics and chemistry will occur under certain conditions of temperature, humidity and time duration. Change and rust. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution.
The economic loss caused by metal corrosion is huge. Choosing a suitable rust inhibitor can effectively maintain the workpiece while reducing costs. The rust inhibitor forms a protective film on the surface of the metal workpiece through physical adsorption (chemical adsorption) to make the workpiece Contact with air, moisture and corrosive media to achieve the effect of rust prevention.
Corrosion causes metal hardware products to become inferior products or waste products lose their use value, reduce the safety factor of the equipment, decrease performance, increase maintenance workload and downtime and even accidents.
The usual causes of rust:
1. Improper use of the product
2. Water erosion
3. The storage environment humidity is too high (70%-90%)
4. Contact corrosion (hand contact, sweat)
5. The parts have been corroded and rusted before rust prevention
6. The storage environment contains corrosive gases (HCL, SO2, etc.)
7. Oil film rupture
Precautions for using playable anti-rust oil:
1. The surface of the workpiece must be kept clean and dry before applying the anti-rust oil;
2. When applying anti-rust oil, employees should not directly touch the workpiece with their hands, and should wear gloves and finger cots to operate;
3. Because the volatilization speed is too fast, it is not suitable for soaking process, which will cause evaporation loss and thickening of oil film;
4. Anti-rust oil should not be mixed with other oils or solvents.
