Why is the polymer cable tray particularly rusty?

    Is the polymer cable tray not made of galvanized material? Why is it so fast? Let us look at the factors that make the polymer cable tray rust particularly fast.
    1. The existence of water.
    In a dry environment, the metal is not easy to rust. The polymer cable trays are built outdoors and will be tested by rain. The presence of water will increase the corrosion of the metal. 2, polymer cable bridge itself raw material quality problems
    Most appear in small polymer cable tray manufacturers, customers are eager to choose cheaper cooperation with some third-rate manufacturers, Of course, the products of the third-rate manufacturers are cheaper and cheaper. The quality of the products of well-known manufacturers is not too outrageous. Because they have brands in them, the quality is guaranteed. If the products are made of inferior raw materials, they must be branded. There will be no visibility.
    3. Pollution in the air. In addition to the oxygen and nitrogen we often say, the air also contains carbon dioxide, sulfur dioxide, nitrogen dioxide, etc. produced by industrial production. These gases combine with the moisture in the air. It will produce acidic substances, which will cause corrosion of the metal cable tray metal.
    4, the characteristics of the metal itself
    The polymer cable tray is made up of a mixture of various metals, and a chemical reaction occurs between the metals. Pure iron is not easy to rust, but pure iron has poor robustness and needs to be mixed with other metals to improve the firmness. Therefore, iron used in industrial production contains impurities, which are highly prone to galvanic corrosion.
    The polymer cable tray is used to protect the cable from external damage, so the quality of the polymer cable tray itself needs to be paid attention to.
