The service life of FRP grids depends on the raw materials, the mode of use and the environment.
In the sewage treatment system, FRP grilles as walkways are needed around the water treatment pool. So how many years can FRP grids be used in sewage treatment?
The service life of FRP grids depends on the raw materials, the mode of use and the environment.
1. The influence of raw materials on the service life of FRP grids:
There are many kinds of raw materials for FRP grille production. The application of raw materials resins depends on the environment in which they are used. The anticorrosion ability of different resins is different.
2. The influence of service environment on the service life of FRP grids
1. FRP grille for ocean operation: The environment for ocean operation is perennial exposure and seawater corrosion, and the service life in such environment is generally 30-50 years.
2. FRP grids for chemical plants: Chemical plants are located in high-temperature environment with high acid and alkali content, and their service life is about 10-20 years.
3. FRP grille for sewage treatment plant: The sewage plant is exposed to the sun all the year round, and there are some acid-base gases. In this environment, its service life is about 15-30 years.
4. FRP grille for car wash room: The car wash room needs to be watered every day. It is in the humid environment all the year round. The use time of FRP grille in car wash shop is about 10-20 years.
3. The influence of operation mode on the service life of FRP grids:
In the process of using FRP grille, we should pay attention not to collide with heavy metal objects, which can easily cause surface damage of products. When using FRP grille in the car washroom, we should pay attention to the front wheel rotation in motion, and not to twist the front wheel after stopping, because this time will break the grille surface 1-2 mm, shadows. Sound use. In the course of using, the specifications should be determined strictly according to the requirements of use. The grid with insufficient load will be broken, damaged or even accident in use.
Above is a summary about the service life of FRP grids in various environments. I hope it will be helpful for you to understand FRP grids.
