Description

Technical Field

[0001] The utility model relates to the field of microporous membrane production, in particular to a PES microporous membrane silica gel baffle. Background Art

[0002] In the production and preparation process of PES microporous membrane coating, the scraping device is the most important component. The size and angle of the baffle between the scraper and the back plate and back roller in the scraping device determine the contact position between the membrane liquid and the substrate.

[0003] The baffles in common film scraping devices are mostly supported by hard materials and have poor deformation ability. However, due to the influence of processing and installation accuracy, the gap between the baffles and the baffle size during the actual assembly process does not match, resulting in gaps between the baffles, scrapers and backing plates. During the coating process, the film liquid easily flows out from the gaps in the baffles, causing unnecessary waste. In addition, the outflowing film liquid comes into contact with the external environment, solidifies and adheres to the surface of the substrate, which also affects the film quality.
