Perforation and wetting of dielectric materials

Wetting with dielectric material

• Wetting with dielectric material
• High relative humidity has a negative effect on the operation of electronic equipment and machines. The Hamish property of a dielectric with water (or another liquid) is represented by the desorption angle. This angle is in the range of 8<900, 8>900. The smaller the value of 8, the higher the body's damping. 8<900 for wet surfaces, 8>900 for non-wettable surfaces

When electrical equipment is used continuously in tropical climates, mold-like decay occurs in the organic dielectric. This phenomenon reduces the dielectric surface resistance and mechanical strength, increases the dielectric loss, and causes degradation in the part where it joins with the metal. If an electric insulating material is introduced into an environment with a certain humidity and temperature, after a certain time, the humidity of the body will have an equilibrium state. If a relatively dry dielectric is introduced into moist air, the moisture will absorb into it by volume. The moisture in the material reaches its saturation value (1) over a period of time, or, conversely, a moist material stored in relatively dry air loses moisture (2) over time.
