Dalian metal surface treatment, cadmium coating has good corrosion resistance, especially in marine atmospheric environments, with better corrosion resistance than other surface treatments. The waste liquid treatment cost in the process of electroplating cadmium is high, so it is not used in general industries and is only used in certain specific environments, such as fasteners for oil drilling platforms and Hainan Airlines aircraft.

Dalian metal surface treatment, artificial intelligence has given rise to exponentially growing application scenarios, further increasing the degree of mechanical substitution for manual labor and enabling many difficult and delicate operations to be completed by machines. The original solid-state solution form cannot meet the rapidly changing dynamic needs of users; The original rigid ecological cooperation model cannot fully meet the needs of users for flexible, diverse, and rapid iteration.

Dalian metal surface treatment coil coating is a professional coating used to coat the surface of steel plates and aluminum plates, and to make pre coated coils. It is an essential industrial coating for social development. In order to adapt to the performance characteristics of the coil, the coating film usually has good flexibility and weather resistance. Roll color coating is composed of resin, crosslinking agent, pigment filler, auxiliary agent, and solvent, and is divided into three parts: primer, topcoat, and back coat.

Dalian metal surface treatment: Before electroplating, the oil seal of the parts should be removed. After removing oil stains, the surface of the parts should be free of oil stains, oil stains, metal shavings, and paint marks from mechanical processing. Components connected by bolts are not allowed to be directly electroplated or chemically treated. Riveted parts, welded parts with gaps, and castings with excessive sand holes should not be electroplated or chemically treated in principle. Otherwise, corrosion may occur due to electrolyte flowing into the gaps; The surface of the workpiece after heat treatment should be cleaned, and there should be no incomplete oxide scale or residue (such as salt, alkali, molding sand, and sintered material caused by incomplete oil stains on the surface of the workpiece before heat treatment), and slight oxide scale and rust corrosion are allowed.

Dalian metal plastic spray paint contains a lot of harmful chemicals such as formaldehyde and benzene, which can easily induce leukemia. Its harm to the human body has the characteristics of long-term, latent, and hidden, so it is easily overlooked by people. The harm of spray painting is greater. Spray painting takes longer than paint mixing, and paint mixing is only a process of adjusting the physical parameters of the paint solution during the use of the coating according to the needs. Usually, a diluent (also known as a solvent or thinner) is used to adjust the viscosity of the paint solution.
