The exterior cleaning agent for high-speed trains is a special type of cleaning agent that requires strong cleaning and protective capabilities. In general, the composition of cleaning agents should include the following aspects:
1. Surfactant: It has good cleaning, dispersing and emulsifying effects, and can effectively dissolve and disperse dirt on the outer skin into water to achieve cleaning effect.
2. Chelating agent: It can undergo chelation reaction with metal ions to dissolve metal dirt such as rust, which helps protect the surface of the outer layer.
3. Corrosion inhibitor: It can reduce the oxidizability of water and prevent surface metals from being oxidized.
4. Rust inhibitor: It can prevent the cleaned outer surface from being affected by oxidation and rust again.
2, Usage method
The use of cleaning agents for the outer skin of high-speed trains should meet the following requirements:
Before using the cleaning agent, the concentration should be adjusted according to the actual situation. Generally, the concentration of the cleaning agent should be 3% to 5%.
2. The cleaning agent should be sprayed passively, that is, the cleaning agent flows to the surface, rather than high-pressure impact, to avoid damage to the outer skin.
When using cleaning agents, the relationship between cleaning time and cleaning temperature should be understood. Generally, the cleaning time is 10-15 minutes, and the cleaning temperature should not be too high, generally not exceeding 50 ºC.
4. After using the cleaning agent, it should be promptly rinsed with clean water to avoid residual cleaning agent damaging the surface of the vehicle.
3, Operating procedures
When using high-speed train outer skin cleaning agent, the following operating procedures should be followed:
Before operation, a comprehensive inspection of the exterior of the high-speed train should be carried out, and it should be confirmed that the windows, doors, lights, and other parts of the high-speed train have been closed to avoid the impact of cleaning agents on the interior of the car.
2. Cleaning agents should be operated in certified cleaning plants, and operators should receive professional training to master the use of cleaning agents and safety operating procedures.
After cleaning, the entire vehicle should be inspected. If residual cleaning agents or other problems are found, they should be dealt with in a timely manner.
Through the above standard specifications, the cleaning work of the outer skin of the high-speed train can be more standardized and regulated, avoiding unnecessary damage to the high-speed train and ensuring its safe operation and beautiful appearance
