Corrosion - Resistant Fiberglass Cable Tray

Corrosion resistance of the material itself: FRP is a composite material composed of glass fiber and resin. Glass fiber has high chemical stability and is not easily corroded by common chemicals such as acids, alkalis, and salts. As a matrix material, resins are of various types, such as polyester resins, vinyl ester resins, etc. These resins have good corrosion resistance and can remain stable in different chemical environments. For example, in chemical production, there are often various acidic or alkaline gases and liquids. FRP cable trays can be exposed to such environments for a long time without being corroded.

Tolerance to different chemicals:

Acid resistance: Generally speaking, FRP cable trays have good tolerance to a variety of acid substances. For example, in the environment of common acids such as hydrochloric acid and sulfuric acid, its performance is relatively stable. This is because the resin matrix can form a protective film under acidic conditions to prevent the acid from further corroding the glass fiber and internal structure, thereby ensuring the integrity and service life of the cable tray.

Alkali resistance: FRP also has a certain resistance to alkaline substances such as sodium hydroxide and potassium hydroxide. In particular, cable trays made of resins with good alkali resistance, such as vinyl ester resin, can maintain good performance in alkaline environments and are suitable for some places involving the treatment or production of alkaline substances.

Salt resistance: In salt spray environments, such as the seaside, offshore platforms, or near some roads using snow-melting salt, metal cable trays are prone to corrosion and rust, while FRP cable trays are not affected. Salts such as sodium chloride in salt spray will not cause significant damage to the structure and performance of FRP, allowing it to be used stably for a long time.

Surface treatment to enhance corrosion resistance: During the production process, FRP cable trays are usually subjected to some surface treatment to further improve their corrosion resistance. For example, adding a layer of resin-rich layer to the surface or covering it with materials such as surface felt can make the surface of the bridge smoother and flatter, reduce the adhesion and penetration of corrosive media on the surface, and thus enhance the overall corrosion resistance.

Long-term stability: The corrosion resistance of FRP cable trays has long-term stability, and there will be no obvious corrosion aggravation over time. Unlike metal materials, it does not suffer from electrochemical corrosion, rust, corrosion perforation and other problems. Therefore, it can maintain good mechanical and protective properties throughout its service life, reducing the maintenance and replacement costs caused by corrosion.
