The electronic industry is one of the pillar industries of the national economy, and it is also a new type of scientific and technological development industry. The protection of cables will be particularly important. The use of cable tray in Jinan can play a role in the situation of cable dust prevention, corrosion prevention and other damage to the service life of cables. The methods of repair and maintenance of cable tray are integrated below. Proper maintenance can extend the service life of cable tray.
Repair of cable tray:
1. Rust treatment
Generally, cable tray is subject to two parts of rust removal with two layers of chlorosulfonated primer. The quality of surface rust removal treatment directly affects the service life of the anti-corrosion project. The on-site rust removal is usually performed with a grinder or manually. After surface treatment, the primer is applied within 4 hours. If new rust is found due to improper handling, it must be re treated.
2. Coating treatment
The coating process is divided into brush coating and roller coating. When brushing or rolling, each layer should be applied repeatedly in a horizontal and staggered manner until uniform, and there should be no leakage.
3. Construction environment requirements
The environment needs to be well ventilated, with a temperature of between 13 ℃ and 30 ℃, not less than 5 ℃, and a relative humidity of within 80%. Construction should not be carried out in strong sunlight. Construction shall not be carried out outdoors in rainy, foggy, or windy climates.
Cable tray maintenance:
1. Avoid placing in hot and humid areas.
2. Avoid contact with corrosive liquids.
3. Special maintenance wax for cable tray can be used for maintenance.
4. Regularly clean the dust and rust on the surface of cable tray.
In addition, during the transportation, loading and unloading of cable tray, the cable tray frame shall be firmly tied to the vehicle to avoid collision and damage to cable tray. When unloading, the cable tray frame shall not be pushed down directly from the vehicle, and collision shall be avoided during handling; When storing, they must be stacked in different categories and must not be knocked. These layers should be separated by soft objects.
Do not place heavy objects on the cable tray to avoid deformation or damage to the anti-corrosion coating of the overweight cable tray. In humid or corrosive environments, corresponding measures should be taken, and any damage should be dealt with immediately; After acceptance, the galvanized cable reel should be placed in a clean and dry place and covered with a cover plate to avoid corrosive substances such as acid and alkali.
Before replacing the bridge, a meeting should be held to discuss and develop a strict set of safety measures and construction plans, which should be reviewed by the motor department. After the audit, prepare various tools and materials, assign personnel, and arrange the specific responsibilities of each person. Before starting work, conduct on-site investigation at the construction site to determine the bridge that needs to be replaced, develop a table, and make detailed records.
