Unique HGN Cartridge Filter With Strong Gel Removal Effect On UV

Unique HGN cartridge filter with strong gel removal effect on UV (curable inkjet ink filtration)

Background: UV-curable inkjet inks are mainly composed of photo-curable resins (photoactive oligomers), reactive diluents (diluted monomers), photoinitiators, colorants, additives, etc., which tend to generate more gel condensation during the ink production. Gel is easy to deform and re-condense, so it requires high filtration efficiency.

Company B is a foreign professional UV ink manufacturing factory and its products are supplied to many large inkjet equipment companies at home and abroad. The meeting with the customer revealed that the current ink filter is using the US filter element. inkThe deep filter has high filtration efficiency, but the filter element has great resistance and low production efficiency. The order peak period often requires three shifts of the factory.

Our technical manager recommended the client to use the PP3 series multi-gradient PP membrane folding filter and HGN series thick glass fiber plus nano membrane folding filter to fit in the UV ink characteristics and solve production problems. Because the folding filter has a large filtering area to improve production efficiency, and the multi-layer thick membrane structure effectively intercepts gels and impurities. What’s more, the thick glass fiber material used in the HGN filter element is twice as thick as the conventional one. So the filter efficiency is on a par with that of the US filter element.

The addition of the nano membrane layer can prevent the fiber from falling off and prolong the service life of the filter element.
