Microfiltration mainly removes tiny particles, impurities or microorganisms in the ink through physical screening to ensure the purity, stability and safety of the ink. Microfiltration can intercept solid particles in the ink (such as pigment aggregates, dust, fibers, etc.) to prevent clogging of the print head, nozzle or tattoo needle; improve the uniformity of the ink and avoid color difference in printing or mottled tattoo color caused by uneven particle distribution.

Microfiltration membranes can intercept particulate impurities such as dust and metal debris, preventing them from causing short circuits or a decline in electrode reaction efficiency inside the battery. For water-based electrolytes, microfiltration can remove microorganisms and prevent their metabolic products from contaminating the electrolyte. In addition, microfiltration technology also has the functions of separating colloids and macromolecular substances, ensuring high purity, and extending battery life.

Microfiltration runs through raw material processing, solvent recovery, wastewater purification and coating processes in wet diaphragm filtration. It optimizes the pore size distribution and impurity control of the membrane through precise physical screening, and can also reduce production costs.
