Abstract
Description
Technical Field
[0001] This utility model belongs to the field of membrane production technology, and specifically relates to an electrostatic elimination device for protective membrane production. Background Technology
[0002] During film processing, due to the need for multiple unwinding and winding and multiple passage through guide rollers, static electricity can easily accumulate on the film. Static electricity can lead to production defects such as corona discharge, and may even cause electrostatic breakdown of the film. Therefore, static eliminators are usually used to remove static electricity from the film during production. However, static electricity on the film during production can attract dust from the air, affecting the production quality of the film. Utility Model Content
