Zinc sheet for high-uniformity zinc-aluminum coating

Abstract

The invention discloses a zinc sheet for a high-uniformity zinc-aluminum coating and relates to the technical field of zinc sheet machining. The zinc sheet for the high-uniformity zinc-aluminum coating specifically comprises a first aluminum coating zinc outer sheet, embedded strips and connecting strips, wherein the right end of the first aluminum coating zinc outer sheet is provided with a second aluminum coating zinc outer sheet; the embedded strips are mounted outside the first aluminum coating zinc outer sheet and the second aluminum coating zinc outer sheet; the upper ends and the rightends of the first aluminum coating zinc outer sheet and the second aluminum coating zinc outer sheet are fixedly welded with mounting strips, the lower edges and the left edges of the first aluminum coating zinc outer sheet and the second aluminum coating zinc outer sheet are provided with mounting grooves, and the upper ends of the surfaces of the first aluminum coating zinc outer sheet and the second aluminum coating zinc outer sheet are fixedly welded with connecting sleeves. The zinc sheet for the high-uniformity zinc-aluminum coating is high in corrosion resistance and thermal insulation,thereby being particularly applicable mounting thermal insulating devices in large household appliances; the mounting grooves and mounting blocks are in engaged connection to firmly connect the aluminum coating zinc outer sheets.

Description

technical field [0001] The invention relates to the technical field related to zinc plate processing, in particular to a zinc plate used for a zinc-aluminum film with good coating uniformity. Background technique [0002] The surface of the aluminum-zinc steel plate is a unique smooth, flat and gorgeous star flower, the base color is silvery white, the special coating structure makes it have excellent corrosion resistance, the normal service life of the aluminum-zinc plate can reach 25a, and the heat resistance is very good , can be used in a high temperature environment of 315 °C, the adhesion between the coating and the paint film is good, and it has good processing performance. It can be stamped, cut, welded, etc., and the surface conductivity is very good. Composed of aluminum and 43.4% zinc, 1.6% silicon, the production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, it is a continuous fusion coating process, 55% alum...

Problems solved by technology

[0004] A fire-resistant galvanized panel for exterior walls is disclosed in the Chinese utility model patent application publication specification CN207714532U. Although the fire-resistant galvanized panel for exterior walls is designed with a layered structure, the overall bending resistance and flexural resistance are enhanced. , improve the quality and service life, and enhance the external aesthetics. However, the fire-resistant galvanized sheet used for the exterior wall has the ability to easily form zinc accumulation on the edge of the lateral opening of the steel sheet during the galvanizing process, resulting in a smaller actual lateral size and less activity. There is no coating on the edge of the zone, and the zinc deposited on the edge of the transverse opening of the zinc plate will easily cause the reinforcement ribs on the zinc plate to wear during the cleaning process, resulting in the scrapping of the zinc plate
