On the Pore Size of Cellulose Acetate Membrane
The pore size of cellulose acetate membrane is related to many functions and cannot be ignored.

Cellulose acetate membrane is widely used in various fields due to its unique characteristics. And the size of the pore is precisely the key. If the pore size is fine, it can block particles and impurities, and make the filtrate clear, just like a fine sieve. It can be used for fine filtration of water and purification of liquid medicine, etc., and can ensure that the obtained liquid is pure and free of impurities.

If the pore size is slightly wider, it is conducive to the passage of macromolecular substances. In some specific separation processes, the required macromolecules can pass through smoothly, leaving other substances, which is of great significance in the separation of biological products.

When preparing cellulose acetate membranes, many factors affect the pore size. Such as the type and ratio of the solvent, which can affect the arrangement and aggregation of molecules during the formation of the membrane, and then change the pore size. For example, the temperature and composition of the coagulation bath have a significant effect on the solidification rate and structure of the membrane, and are also closely related to the pore size. If properly controlled, a membrane with a suitable pore size can be prepared on demand.

Furthermore, accurate means of detecting the pore size of cellulose acetate membrane are also indispensable. Sophisticated detection methods can truthfully reflect the pore size, providing a reliable basis for the performance evaluation and subsequent application of the membrane.

In summary, the principle of the pore size of cellulose acetate membrane can be well regulated and tested in order to make it apply its strengths in various fields and make the best use of it for the improvement of the process and the improvement of the product.
