Silica sol is difficult to concentrate. Try adding this raw material!

The concentration stage of silica sol production is a process with high energy consumption and a long cycle. The traditional concentration method usually adopts the vacuum dehydration method to obtain the required concentration of silica sol. Today, the editor will introduce to you the application of inorganic ceramic membranes in the concentration of silica sol.

Inorganic ceramic membranes have the advantages of high stability, high separation efficiency, acid and alkali resistance, chemical solvent resistance, high temperature resistance, etc. Especially, they have the advantages of high mechanical strength, easy cleaning, strong renewability, simple operation and maintenance, and long service life.

For the application project of enriching silica sol through a large number of ceramic membranes, there are reliable technologies and parameters for using ceramic membranes to enrich silica sol. To achieve a breakthrough in membrane separation research technology: Compared with organic ultrafiltration membranes, organic ultrafiltration membranes Large-capacity organic ultrafiltration membranes can have a silica sol concentration of up to 30%. When the concentration exceeds 30%, the backflow is particularly severe, the loss is very fast, and it is easy to cause irreversible damage. At this time, only new membrane elements can be changed. Inorganic ceramic membranes can have a silica sol concentration of over 40%. After cleaning, they can quickly restore their capacity and continue to be used.

Inorganic ceramic membranes can not only effectively remove diluted hydrosol, but also remove suspended solids and particles, increase the efficiency and quality of filtration, be easy to clean, have strong renewability, save manpower and material resources, greatly extend the service life of equipment, and bring benefits to silica sol manufacturers.
