Description

Technical Field

[0001] This utility model relates to the field of fabric coating technology, specifically a coating device for PPS filter material aramid nanofiber dispersion. Background Technology

[0002] Aramid nanofiber modified PPS filter media is a composite filter media. It is prepared using a needle-punching process to create a PPS gradient structure filter media. The dust-facing side contains ultrafine PPS fibers, while the base fabric is high-strength PTFE to ensure sufficient strength. The dust-receiving side contains conventionally fine PPS fibers. This gradient structure design makes the filtration mechanism of the filter media tend towards surface filtration, effectively reducing filtration resistance. Secondly, aramid nanofiber dispersions of different mass fractions are prepared, coated onto the surface of PPS needle-punched felt, and then dried and cured to obtain the composite filter material.

[0003] In the production process of filter media coating equipment, it is usually necessary to clean the filter media. Ordinary filter media coating equipment uses brushes to clean one or both sides of the fabric. However, after the brushes have been cleaning the fabric for a long time, a large amount of debris will accumulate inside the brushes, affecting the cleaning effect.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content
