Description

Technical Field

[0001] The utility model relates to the technical field of open plates, in particular to a corrosion-resistant hot-dip galvanized open plate. Background Art

[0002] A flat plate is a plate processed by cold rolling or hot rolling, and is widely used in construction, manufacturing and other fields. Steel plates are usually in coils when leaving the factory, and become flat plates after being flattened by machines, so they are called flat plates. The process of hot-dip galvanized flat plates involves hot-dip galvanizing the steel plates, which is an effective way to prevent metal corrosion. A zinc alloy coating is formed on the surface of steel through an iron-zinc reaction, which has a long-term anti-rust effect.

[0003] The hot-dip galvanized plates currently on the market can greatly improve the corrosion resistance of the plates, but they will be transported several times from the completion of production to the actual use. The friction and collision generated during this period can easily lead to local wear of the plates, especially the lower surface of the bottom hot-dip galvanized plates. The hot-dip galvanized layer on the surface will often be worn away over a large area. At this time, the original steel material in the plates will be exposed to humid air, causing rust and affecting subsequent normal use. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: a corrosion-resistant hot-dip galvanized flat plate, comprising a substrate 1, the substrate 1 is an F55 stainless steel flat plate, containing high content of chromium and nickel, these elements can form a dense oxide film, effectively preventing oxygen and moisture from corroding the metal surface, the outer surface of the substrate 1 is provided with a galvanized layer 2, the galvanized layer 2 is formed by immersing the substrate 1 in a pre-heated zinc liquid, so that the zinc metal reacts chemically with the surface of the steel plate, thereby forming a dense zinc-iron alloy protective film, this surface treatment method can prevent the steel plate from rusting due to oxidation, The corrosion resistance of the steel plate is improved. A plurality of through holes 3 are evenly formed on the outer surface of the galvanized layer 2. A sacrificial anode rod 4 is inserted into the inner wall of the through hole 3. The sacrificial anode rod 4 is an aluminum alloy rod. The zinc contained in the sacrificial anode rod 4 is a common heavy metal with an atomic number of 30, a relative atomic mass of 65.37, a density of 7.14 g / cm3, a valence of 2, and a melting point of 420°C. The standard electrode potential of zinc is -0.76 V (SHE). The stable potential of high-purity zinc in seawater is -0.82 V (SHE). This is a relatively active metal. For steel and commonly used metal structural materials, it is negatively charged. The zinc anode is not suitable for high-resistance soil or fresh water. It is usually used in seawater, certain chemical media and low-resistivity soil or tidal flats. The theoretical power generation of zinc and zinc alloy anodes is small, but its current efficiency as a sacrificial anode is very high. It can be consumed by oxidation corrosion before the substrate 1, thereby enhancing the corrosion resistance of the base fabric 1. The outer wall of the sacrificial anode rod 4 is tightly against the inner wall of the through hole 3. A circular hole 5 is opened in the center of the upper surface of the sacrificial anode rod 4. The outer wall is annular and evenly provided with a plurality of grooves 6. The circular hole 5 and the grooves can improve the toughness of the sacrificial anode rod 4, and can facilitate the insertion of the sacrificial anode rod 4 into the through hole 3. The outer surface of the galvanized layer 2 is provided with an enhancement layer 7. The enhancement layer 7 is a dendritic macromolecular flame retardant and heat-insulating protective coating, which provides impact resistance, wear resistance, scratch resistance, corrosion resistance, acid and alkali resistance, and can enhance the corrosion resistance of the base cloth 1. Both ends of the inner wall of the through hole 3 are processed with bevels 8, which can facilitate the insertion of the sacrificial anode rod 4 into the through hole 3.

[0018] During the use of the corrosion-resistant hot-dip galvanized flat plate, after the substrate 1 is manufactured, a plurality of through holes 3 are evenly opened on its surface, and after the sacrificial anode rod 4 with the circular hole 5 and the groove 6 is concentrically aligned with the through hole 3, a hammer or other stamping workpiece is used to completely embed the sacrificial anode rod 4 into the through hole 3, and then a galvanized layer 2 is provided on the outer surface of the substrate 1, and after the galvanized layer 2 is formed, a layer of enhancement layer 7 is provided on its surface, and after the enhancement layer 7 is enhanced, the galvanized layer 2 and the enhancement layer 7 can provide high-quality corrosion resistance to the inner substrate 1 for a long time. When the base fabric 1 is stored and transported to the site of use, when the galvanized layer 2 on the lower surface is worn and detached over a large area during transportation, the sacrificial anode rod 4 can be consumed as a negative electrode by oxidation reaction due to its strong metal reducing property, and can be consumed by oxidation corrosion before the substrate 1, thereby enhancing the corrosion resistance of the base fabric 1 for normal use during the subsequent formal assembly period.
