The metal protective film in the metal is isolated from the metal of the protective film portion of the dust metal surface and the oxygen in the air interacts with other oxidizing agents to form a metal oxide protective film on the metal surface. Metallic surface films may also be produced as a result of interaction with other gases, vapors or liquid media. However, in practical cases, the metal oxide film is more temperate. In some cases, the protective film can grow to a significant thickness, while in another case, the resulting film is very thin and as thin as only a few molecular layers.
In the process of formation of a viscous protective film in a metal, when a medium acts on a metal, a film formed by a layer of molecules is formed due to the A bond of the two, and then the medium atom (or ion) and the metal atom (more correctly Soul A should be ions and electrons. It will also diffuse through the membrane. When it meets in the membrane, it combines to form a new decay product and thickens the membrane.
Characteristics of viscous protective film in metal
1. The viscosity is stable, easy to use, easy to tear and easy to stick, no residue.
2. PE material, environmental protection and energy saving.
3. Breathability is better, and the paste effect is beautiful.
Surface protection of aluminum-plastic board, stainless steel board, color steel plate, aluminum plate, aluminum profile, floor, carpet, glass, security door and other materials during transportation and processing.
