FRP gratings are widely used in sewage treatment plants. What are the specific applications in sewage treatment plants? Xiaobian takes everyone to understand together!
In terms of sewage treatment, the FRP grid can be used as the paving material for the operating platform below the cooling tower, can be used as a hanger for the biochemical water treatment tank, and can also be used as an inspection walkway for the sewage treatment plant.
In the sewage treatment system, a large number of guardrails and FRP grids are used as aisle boards around the water treatment tank. In traditional engineering, the guardrail and FRP grille are made of metal materials, such as welding with steel pipes, and then the surface is coated with anti-rust paint. Many of the treated sewage is highly corrosive. The splashed water drops or volatile water vapor have a strong corrosive effect on metal parts. For a long time, these metal parts are rusty, even damaged, and exist. Many hidden dangers.
Compared with metal profiles, FRP gratings have light weight, high strength, and excellent corrosion resistance, which can fundamentally solve the problems of easy corrosion and difficult maintenance of metal guardrails and FRP gratings, and the service life is greatly extended, and the comprehensive cost Controlled; beautiful appearance and various colors, and can keep bright color and luster in corrosive environment, which can beautify the environment.
The installation of the column can take three forms: 1, fixed to the side of the foundation by expansion bolts; 2, set a reserved hole in the corresponding part of the foundation, the column is inserted during installation, and then filled with cement mortar; 3, in the foundation Corresponding parts are embedded in the iron plate, the vertical iron plate is welded on it, the column and the vertical iron plate are fixed by screws.
