The product performance of FRP grating used in sewage plants is provided by its production raw materials, among which unsaturated polyester resin is the main raw material that makes the grating plate have excellent corrosion resistance. As the base material of grating plates, resin has the advantages of room temperature curing molding, and its process performance is very flexible. It is especially suitable for the production of fiberglass grating products.
In the sewage treatment system, a large number of guardrails, grilles, water treatment tanks, etc. are used. In traditional projects, guardrails and grilles are mostly made of metal materials, such as welded steel pipes coated with anti-rust paint, which have strong corrosion resistance. However, splashed water droplets and water volatilization corrode metal very seriously. Over time, metal corrodes or even damages, posing many safety issues.
Due to the complex water quality of sewage treatment plants, some water quality has high pH value and strong corrosion effect. This requires raw materials such as grilles, walkway boards, and guardrails in sewage treatment plants to have anti-corrosion effects. General iron materials obviously cannot meet the needs of use. Stainless steel has high cost and shortcomings in service life.
Most of the fiberglass gratings in sewage plants are of size 38*38 and can bear up to 4 tons per square meter. Therefore, don't be afraid of the fiberglass grating being crushed. In addition, fiberglass grating is corrosion-resistant and has little impact on it regardless of usage. As a new type of composite material, fiberglass grating is particularly suitable for sewage treatment and corrosive environments. The use of fiberglass materials in sewage treatment is also an inevitable trend. Not only FRP gratings, sewage treatment plants can also use FRP guardrails, FRP walkways and other equipment, which have a series of advantages such as long service life, low cost, safety and reliability, no maintenance, and beautiful appearance.
Most of the FRP gratings in sewage treatment plants are made of fiberglass. The emergence of fiberglass materials has solved the anti-corrosion problem of products and can be used for a long time in harsh environments such as acid and alkali corrosion. It is a perfect replacement for traditional metal materials. Many sites require the use of fiberglass operating platforms, especially in some corrosive places or working environments.
