At present, FRP transparent grating has been widely used in sewage treatment plants, but what are the specific applications of FRP gratings in sewage treatment plants?
In terms of sewage treatment technology, FRP transparent grid can be used as the paving material for the operating platform under the cooling tower. FRP grating can also be used as the hanger of the biochemical water treatment tank and the maintenance walkway of the sewage treatment plant, and has many applications. In fact, in the sewage treatment system, a large number of guardrails and FRP gratings are required around the water treatment tank as aisle slabs. In the past engineering applications, guardrails and FRP gratings are made of metal materials such as steel pipe welding, and the surface is coated with anti-rust paint. However, many sewage treated daily are highly corrosive, and the splashed water droplets or water vapor have a strong corrosive effect on metal parts. After long-term use, these metal parts are rusted or even damaged, and there are many hidden dangers.
Compared with metal profiles, FRP transparent grating has the advantages of light weight, high strength, and excellent corrosion resistance. The cost is controllable; and the FRP grille has a beautiful appearance and various colors, which can always maintain bright colors in a corrosive environment, and play a role in beautifying the environment.
The FRP transparent grille is secondary processed on the basis of the molded grille, so it also has most of the features of the FRP molded grille, as follows:
1. Anti-aging: The normal service life of the general glass fiber reinforced plastic cover is about 20 years. The service life of the metal cover is only about 5 years, and the service life of the wooden cover is even shorter, only about 3 years.
2. Corrosion resistance: It can resist the corrosion of various chemical media. Aging of a product is also a manifestation of corrosion, more precisely chronic corrosion. For example, humid air is a chronically corrosive environment. The metal cover will corrode slowly when used in humid air for a long time, which is what we often call rust.
3. High temperature resistance: FRP products have good flame retardant properties, which is mainly due to the glass fiber production raw materials of FRP products. Although there are many types of glass fibers, excellent flame retardant properties are a common feature of various glass fiber rovings.
4. Light weight and high strength: Although the FRP cover plate has been processed twice on the basis of the forming grid, its weight is still much lower than that of the metal cover plate, and the product strength and toughness are also much higher than those of the cast iron cover plate, so the product handling And the installation is very convenient and labor-saving;
5. Anti-theft: Due to the special composite material type of the FRP cover, different from the metal cover, it can be sold and has almost no secondary recovery value, thereby indirectly reducing the risk of theft and other risks.
In addition to the above features, another outstanding advantage of FRP transparent grille is the anti-skid performance, which can increase the safety of the product environment and reduce the occurrence of accidental slipping accidents. FRP transparent grating can choose pattern cover, sand paving cover and flat cover. Because its contact area is larger than that of molded grating, its anti-skid performance is better than that of simple grating. Among them, the anti-skid performance of sand paving cover is very good.
