Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Please combine and refer to fig. 1 and fig. 2, the utility model provides a galvanized steel sheet for elevator lateral wall, refer to fig. 1, the utility model discloses a steel sheet 1, steel sheet 1's surface attachment have zinc alloy cladding material 2, and zinc alloy cladding material 2's surface attachment has double-deck passive film 3, and double-deck passive film 3's outside is attached to there is seal coat 4. Since the corrosion resistance of the galvanized steel sheet is different from that of the stainless steel sheet, it is required to further improve the corrosion resistance and platability of the galvanized steel sheet.
Preferably, the galvanized steel sheet has a thickness of 1.5-2.0 mm.
In one embodiment, the zinc alloy coating 2 is a hot dip galvanized zinc alloy coating 2. Hot dip galvanization has many advantages, such as that molten zinc can be easily and uniformly covered on the whole steel surface, including the key inner part of the concave part, and the steel plate 1 can be fully protected; meanwhile, the zinc alloy coating 2 has strong adhesive force and long service life. The surface of the steel plate 1 is attached with a zinc alloy coating 2, the zinc alloy coating 2 can be formed by adding a small amount of alloy elements including magnesium, aluminum, nickel, vanadium and other metal elements on the basis of a pure zinc coating to improve the corrosion resistance of the coating and improve the quality of the coating, and good platability and corrosion resistance are achieved through reasonable proportion of the magnesium, aluminum, nickel, vanadium and other elements. The magnesium has obvious effect of improving the corrosion resistance of the plating layer, when the magnesium content in the plating layer is lower, the corrosion resistance of the plating layer is improved quickly along with the increase of the magnesium content, and because the oxidation film of the aluminum is compact, the continuous oxidation of the surface of the galvanizing solution can be effectively prevented, so that the addition of a certain amount of aluminum in the plating solution added with the magnesium has an inhibiting effect on the oxidation of the plating solution.
In another embodiment, the double-layered passivation film 3 includes a rare earth passivation film and a molybdate passivation film, and the molybdate passivation film is coated on a surface of the rare earth passivation film. The passive film is an effective means of enhancing the corrosion resistance of zinc alloy coatings exposed to air. The method for coating the passivation film has the advantages of simple process, low cost and good corrosion resistance, and the double-layer passivation film 3 can further overcome the defects of insufficient thickness of a single-layer passivation film, insufficient corrosion resistance and insufficient stability of passivation salt. The rare earth-molybdate two-stroke passivation treatment can be adopted, the rare earth passivation solution is coated on the surface of the zinc alloy coating for curing, and then the molybdate passivation solution is coated on the galvanized steel plate treated by the rare earth passivation solution for curing. The double-layer passive film 3 can effectively relieve the corrosion rate of the galvanized plate.
Preferably, the sealing layer 4 is a silica sol type glass transparent film or a composite PVC film, which can further protect the surface of the galvanized steel sheet and prevent the corrosion and damage of the galvanized steel sheet accelerated by scratches and the like caused when passengers take the elevator.
Preferably, referring to fig. 2, a reinforcing rib 5 is further provided on one side surface of the galvanized steel sheet. Further, the reinforcing ribs 5 are handrail-shaped. The reinforcing ribs 5 are arranged, so that the strength of the galvanized steel plate can be further improved, and the strength difference between the galvanized steel plate and the stainless steel plate is made up; the reinforcing ribs 5 can extend outwards to form a handrail shape, so that the appearance is attractive, and the practicability is improved.
