Hot dip galvanizing is the process of coating the surface of cable trays with a layer of zinc, which is adhered to the surface of the tray through electrolysis, forming a zinc layer. Hot dip galvanizing involves immersing cable trays in molten zinc solution, covering the surface of the trays with a uniform and dense layer of zinc.
The zinc layer thickness of hot dip galvanizing is generally between 5 and 15 μ Between m, and the thickness of the zinc layer for hot-dip galvanizing is generally between 45 and 100 μ Therefore, the anti-corrosion performance of hot-dip galvanizing is better.
The surface finish of hot-dip galvanizing is higher than that of hot-dip galvanizing, but the surface of hot-dip galvanizing is more uniform and flat.
Hot dip galvanizing is suitable for occasions with high requirements for surface smoothness and less stringent requirements for corrosion resistance, such as building exterior wall hooks, automotive components, etc; Hot dip galvanizing is suitable for occasions with high requirements for anti-corrosion performance, such as marine engineering and chemical equipment.
In summary, hot-dip galvanizing and hot-dip galvanizing have their own advantages and disadvantages, and the specific selection should be comprehensively considered based on the usage environment and requirements.
The difference between hot-dip galvanizing and plastic spraying for cable trays
The hot-dip galvanizing and spray molding of cable trays are both used to prevent corrosion and extend their service life, but the difference lies in:
Hot dip galvanizing is the process of immersing cable trays in a hot dip galvanizing pool to form a zinc layer on the surface. Spray molding is the process of spraying paint on the surface of cable trays to form a protective layer.
Hot dip galvanizing has better corrosion resistance and can be used for longer in harsh environments. The corrosion resistance of spray molding is slightly inferior, but it is more aesthetically pleasing in appearance.
Hot dip galvanizing requires higher cost and time, but can provide longer lasting protection effects. In contrast, spray molding is relatively cheap and fast, but requires regular inspection and maintenance.
Therefore, when selecting the material and treatment method of cable trays, it is necessary to comprehensively consider the specific environmental requirements and economic strength.
