Scope

Scope: This document specifies the scope, terms and definitions, material performance and requirements, coating systems, coating application and quality inspection of cold spray zinc coating protection technology for steel structures of lifting machinery. This document is applicable to cold spray zinc protection coating for steel structures of lifting machinery. Cold spray zinc protection coating for steel structures in other fields can be used for reference; Main technical content: Cold spray zinc is a low-VOC green and environmentally friendly product with excellent anti-corrosion performance, suitable for application in various harsh atmospheric environments. It also has good mechanical properties such as resistance to cracking and impact resistance, as well as advantages of friendly construction and good compatibility. The microstructure of cold spray zinc shows a three-dimensional spherical network formed by ultra-pure and ultra-thin graphene and zinc powder. The protection mechanism comes from the multi-functional synergistic effect of barrier protection, cathodic protection, and inhibition of corrosion spread. The atomic-layer multi-functional protection technology can simultaneously inhibit chemical and electrochemical corrosion, enabling the coating film to achieve extremely long-lasting anti-corrosion performance. Therefore, cold spray zinc is a new type of low-pollution coating product that meets the requirements of reducing global pollution emissions and controlling safety risks. Currently, cold spray zinc has been widely used in bridge, power, and municipal fields, achieving good economic and social benefits. At present, the anti-corrosion of steel structures in the lifting machinery industry is still mainly based on the traditional epoxy-zinc anti-corrosion system, which cannot fully meet the market demand in terms of protection durability. To further promote the development of lifting machinery protection coating technology and meet the requiremen
