What is the cause of excessive static electricity in PET film for electrical insulation
 Apr 15, 2022|View:206

One of the characteristics of electrostatic phenomena is adsorption. Friction on the surface of the PET film for electrical insulation, peeling of the film coil, or high-speed operation of the film, will form static electricity. If there is dust near the film, paper scraps, hair, etc. . It can be absorbed, and affect the quality of the product film (especially the capacitor film). When static electricity is serious, it may cause fire and electric accidents. It is known that the static electricity of the polyester film is too large, which has a bad effect on the subsequent processing and the processed products. For example, the static electricity of the adhesive PET film for electrical insulation can be determined by the static electricity measuring instrument, which is usually about 500V.


PET film for electrical insulation


PET film for electrical insulationis a polar electrical insulating material, which makes the charge generated by friction, shear, and so on can not be transferred, and accumulates on its surface to form static electricity. Electrostatic size and electrical properties of PET film for electrical insulation. Application of additives. And the process of making films. Because they directly affect the structure and properties of the surface of PET film for electrical insulation, such as the crystallinity of the surface layer, the number and orientation of polar groups, the size of the contact area between the two films, and so on. The difference between the two electrostatic surfaces of PET film for electrical insulation can also be explained.


Solution:


From the resin, additives, the process to find out the cause and be targeted to solve;


The electrostatic eliminator is used in film making and post-processing of film;


Surface coating conduction;


Use of antistatic agents/resins.
