(1) With a thick and dense pure zinc layer covering the steel surface, it can avoid the contact between the steel substrate and any corrosive solution and protect the steel substrate from corrosion. In general atmosphere, a thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is difficult to dissolve in water, so it plays a certain protective role on the steel matrix. If zinc oxide forms insoluble zinc salt with other components in the atmosphere, the anti-corrosion effect is more ideal.
(2) It has an iron zinc alloy layer, which is dense and has unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere.
(3) Due to the firm combination, zinc iron is miscible and has strong wear resistance.
(4) Because zinc has good ductility and its alloy layer is firmly attached to the steel base, hot-dip plated parts can be formed by cold stamping, rolling, wiredrawing, bending, etc. without damaging the coating.
(5) After hot-dip galvanizing of steel structures, it is equivalent to an annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during steel forming and welding, and is conducive to turning of steel structures.
(6) The surface of hot-dip galvanized parts is bright and beautiful.
(7) Pure zinc coating is the most plastic zinc coating in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is flexible.
Trunking cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on the shielding interference of control cables and the protection of environmental cables in heavy corrosion.
Advantages and disadvantages of ladder type, tray type and trunking cable trays: the ladder type junction cable tray has good ventilation performance and is not dust-proof and interference proof. Trunking and tray type junction bridge have dust-proof and anti-interferen
