Technical Field

[0001] This utility model relates to the field of water-based coating filtration technology, specifically a filtration device for water-based coating production. Background Technology

[0002] Water-based coatings are coatings that use water as a solvent or dispersion medium. They are a relatively new type of coating on the market and include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings). Water-based coatings use water-soluble resins as film-forming agents, with polyvinyl alcohol and its various modified forms being representative examples. In addition, there are water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins, etc.

[0003] Traditional filtration devices used in water-based coating production are prone to filter clogging, requiring frequent shutdowns for cleaning. They also suffer from low filtration efficiency, residue buildup, increased costs, and are unsuitable for batch processing. Therefore, those skilled in the art have proposed a filtration device for water-based coating production to address the problems mentioned above. Utility Model Content
