Enameled Square Aluminum Wire

The main process of enameled wire is coating. This process is a crucial step for the finished enamelled wire.

The coating process is to make the conductor attached to the paint liquid according to the wire material, shape or specification and the variety of paint liquid has different coating methods.Low viscosity paint with felt method is the most commonly used paint method in China at present, high viscosity paint can only use mold method. Due to the requirement to reduce air pollution, the proportion of high viscosity paints is increasing. The use of mold method is becoming more and more extensive for commonly used enamelled wire paints containing solvents when the coating is too thick, the diffusion and evaporation of the inner layer of solvents is more difficult and the paint liquid will flow under the action of gravity. In order to ensure the quality of the paint film, a complete paint film is generally formed by painting and drying several times. This is a feature of enamelled wire production - "thin paint and more paint". 

The maximum paint thickness specified in the electromagnetic line standard is limited by diffusion, evaporation and gravity. The number of paint passes can be controlled to control the paint thickness of each paint application. If the number of paint passes is more, the paint thickness of each paint application can reduce the paint liquid after the solvent evaporates to form the paint film. The paint thickness is reduced to the thickness of the paint film The thickness of the paint film can be controlled by controlling the number of paint passes and the viscosity of the paint liquid in the painting process. In order to achieve uniform painting, in addition to the need for painting installation, there should be a paint supply system with a metering pump automatically quantified paint is a more advanced paint supply system.
