Inkjet printing

In recent years, inkjet printing has experienced rapid development due to the growth of the packaging printing and color ceramic tile industries. There is a demand for better printing quality, faster printing speed, and reduced maintenance costs. However, the presence of dissolved gases and tiny bubbles in the ink can cause issues such as printing disconnections, mis-sprays, and ink dripping. These problems affect printing speed, result in quality defects, and increase downtime and maintenance costs. Therefore, solving the degassing problem during the inkjet printing production process has become crucial to ensure the smooth and high-speed operation of printers.

Inkjet printing

In recent years, inkjet printing has experienced rapid development due to the growth of the packaging printing and color ceramic tile industries. There is a demand for better printing quality, faster printing speed, and reduced maintenance costs. However, the presence of dissolved gases and tiny bubbles in the ink can cause issues such as printing disconnections, mis-sprays, and ink dripping. These problems affect printing speed, result in quality defects, and increase downtime and maintenance costs. Therefore, solving the degassing problem during the inkjet printing production process has become crucial to ensure the smooth and high-speed operation of printers.

To address the issue of dissolved gases and tiny bubbles in the ink, Sci-Nano offers the MDG-M6 degassing membrane product. This product utilizes a PTFE hollow fiber membrane at its core. With its well-designed membrane module structure, superior gas removal efficiency, and long service life, the MDG-M6 degassing membrane effectively and promptly removes dissolved gases and tiny bubbles in inkjet printing. It meets the requirements of manufacturers in terms of printing quality, speed, and other various needs.

As the ink passes through the MDG-M6 component, it flows outside the PTFE hollow fiber membrane filament. Due to the gas partial pressure, the dissolved gas and tiny bubbles in the ink continuously enter the membrane filament from the outer wall. This process prevents the ink and other liquids from passing through. By flowing along the outer wall of the membrane, the module achieves high flux, low pressure loss, and efficient degassing rate. As a result, it prevents printer nozzle clogging, improves image printing quality, enhances printing repeatability, and lowers business operating costs. The MDG-M6 degassing membrane is suitable for degassing various inks, such as pigment ink, dye ink, solvent-based ink, and UV ink.
