The invention patents for the 808 electrolytic cathode bags products that are used in both soluble and insoluble anode processes. To cater for various on-site industrial and mining conditions, electrolytic diaphragm cloth products are categorized to general-purpose, low-water permeable, high-water permeable, low-current resistance, corrosion-resistant, and other types.

Water permeability and electrical resistivity are both tracked and monitored throughout production. On average, a comprehensive test of fabric density, tightness, gram weight, water permeability and resistivity are performed for every 20 bags. Each of the nickel diaphragm electrolytic bags that Bolian supplies has a tracking code, enabling it to be traced from the very beginning of the manufacturing process to the final ready-made product, ensuring high-quality products and diverse range, strict quality control, customer guidance and reliable technical support, Bolian is a diaphragm filter cloth manufacturer that you can rely on.
