Coating is the process of applying an enameled wire on a metal wire to form a uniform thickness of a given paint layer. This is related to several physical phenomena and painting methods of liquids. When the liquid flows, the molecules collide with each other, causing one layer of molecules to move with the other. Due to the interaction, the latter layer of molecules hinders the movement of the previous layer of molecules and thus shows activity. Sticky, this is called stickiness.
Different paint methods, different enameled wire specifications require different paint viscosities. The size of the viscosity is mainly related to the size of the resin, the molecular weight of the resin is large, the viscosity of the paint is large, and the thick threads used for the coating are better because of the mechanical properties of the paint film. The viscosity of the coating thin line is small, the molecular weight of the resin is small, the coating film is uniform, and the paint film is relatively smooth.
There are molecules around the molecules in the liquid. Gravity between these molecules can reach a temporary balance. The molecular layer on the surface of the liquid is attracted on the one hand by the attraction of the liquid molecules and on the other hand its force is directed to the depth of the liquid.
At the same time, on the other hand, the gas molecules are gravitational, but the gas molecules are smaller and farther away than liquid molecules. Therefore, the molecules on the liquid surface are attracted by the gravity inside the liquid, so that the surface of the liquid shrinks as much as possible to form a bead shape. In the same geometric volume, the spherical surface has the smallest surface area. If the liquid is not affected by other forces, it is always spherical under surface tension.
