(1) Appearance hygiene: It is necessary to remove the nature of the imported bearing appearance and the conditions at the time. Commonly used methods are solvent removal method, mechanical hygiene method and chemical treatment hygiene method.
(2) The surface is dry and cleaned and can be dried by filtered dry compressed air. It may be dried with a drier at a temperature of 120~170 °C; finally, it is dried with a clean gauze.
Corrosion of imported bearings is caused by various connotations and external factors; ways to avoid rusting of imported bearings are:
(1) Immersion method: some small imported bearings are selected to be immersed in anti-rust grease; the thickness of the oil film can be reached by controlling the temperature or viscosity of the anti-rust grease; it is adhered to a layer of anti-rust grease.
(2) Brushing method: When brushing, pay attention to uniform coating on the appearance of imported bearings; do not accumulate; also pay attention to avoid leakage coating.
(3) Spray method: Some large-scale rust-proof materials are not suitable for oiling by immersion method; usually, the compressed air is sprayed with air at a pressure of about 0.77 MPa. The spray method is suitable for solvent-diluted rust-proof oil or thin layer. Anti-rust oil. It is necessary to choose a comprehensive fire prevention and labor protection method.

Construction building edge protection temporary security fence is a type of barrier used in construction sites to provide safety and security. This fence is designed to protect workers, visitors, and the general public from potential hazards such as falling debris, open trenches, and other dangerous construction activities.
These fences are typically made from strong, durable materials like steel or aluminium, and are designed to withstand harsh weather conditions and heavy impacts. They are also often brightly colored or marked with reflective materials to ensure they are highly visible.
The main purpose of these fences is to prevent unauthorized access to the construction site, helping to reduce the risk of theft, vandalism, and trespassing. They also serve to protect the surrounding environment from potential damage or contamination from construction activities.
In addition, these fences can also serve as a useful tool for managing traffic around the construction site, directing vehicles and pedestrians safely around the area.
Construction building edge protection temporary security fences are easy to install and dismantle, making them a cost-effective and practical solution for construction site safety and security. They can be easily adjusted or relocated as the construction project progresses.
