Surface treatment is a process for manually forming a surface layer on the surface of a substrate material that is different from the mechanical, physical, and chemical properties of the substrate. The purpose is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product.

For the processing of container Accessories and lashing system parts, mainly mechanical grinding, chemical processing, surface heat treatment, spraying surface and other processes, such as: container steel panel fittings (includingContainer roof panel, Side panels, corner posts, etc.) According to the production process of the general container and the characteristics of the coating system, the surface of the container steel plate is usually treated with automatic shot blasting and the surface is sprayed with zinc-rich primer (mainly to prevent the steel plate from rusting and better adhesion when spraying the paint after the box is finished). On the box), then apply the shop primer, after the completion of the steel plate forming, assembly and final assembly, the second blasting of the welding area, and then into the container full-box painting process, in order to make the container more durable and long-lasting;

The surface of the container panels is mainly sprayed with epoxy zinc-rich primer, such as container hinges, door locks, and other container twist locks, cones and the like are all surface galvanized; among them, epoxy zinc-rich primer It is a special coating composed of epoxy resin and zinc powder as main raw materials, thickener, filler, auxiliary agent and solvent. Mainly used in steel pipes, storage tanks, steel structures, containers, etc.Zinc plating refers to the surface treatment of plating a layer of zinc on the surface of metal, alloy or other materials for aesthetics and rust prevention.
