Application of inorganic ceramic membrane in silica sol concentration

The concentration stage of silica sol production is a process that consumes a lot of energy and has a long cycle. The traditional concentration method generally uses atmospheric pressure reduction dehydration to obtain the desired concentration of silica sol.

Nowadays, organic ultrafiltration membrane concentration method is widely used. However, in the process of concentrating silica sol, organic ultrafiltration membrane exhibits poor stability, low temperature resistance, fast loss, short service life, high replacement frequency, affects production progress, and high cost, which increases enterprise costs.

The inorganic ceramic membrane produced by our company has the advantages of high stability, high separation efficiency, acid and alkali resistance, chemical solvent resistance, and high temperature resistance. Especially, it has high mechanical strength, easy cleaning, strong renewability, simple operation and maintenance, and long service life.

Our company has mastered reliable ceramic membrane application technology and parameters for silica sol concentration through a large number of ceramic membrane applications, achieving technological breakthroughs in membrane separation research. Compared with organic ultrafiltration membranes, the processing capacity of organic ultrafiltration membranes can only concentrate silica sol to 30%. After the concentration exceeds 30%, the organic ultrafiltration membrane wears out severely, loses quickly, and is prone to irreversible damage. At this time, new membrane components can only be replaced; Inorganic ceramic membranes can concentrate silica sol to over 40% and quickly restore production capacity after cleaning, allowing for continued use.

Inorganic ceramic membrane filtration technology can not only effectively remove water from dilute sol, but also remove suspended or particulate matter, increasing the efficiency and quality of filtration, easy to clean, highly renewable, saving manpower and material resources, greatly improving the service life of equipment, and bringing profits to silicone adhesive manufacturers.
