On cellulose acetate semipermeable membrane
The ancient masters of good skills used a clever method to create a thing called cellulose acetate semipermeable membrane. This membrane is also unique, and it has significant effects on the separation and filtration of things.

Look at its quality, cellulose acetate is made, and the structure is exquisite. Its molecules are arranged in an orderly manner, making the membrane semipermeable. The so-called semipermeable is to allow specific particles to pass through and block the rest. Such as water molecules and small molecule solutes, which can pass through the membrane smoothly; however, the quality of macromolecules, such as proteins, cannot pass.

In practical use, there are many benefits. In the pharmaceutical industry, if you want to obtain pure medicine, you often use cellulose acetate semipermeable membrane to filter impurities. Make the impure substances in the medicine stay outside the membrane, and the liquid of the purified medicine permeates the membrane, so that the quality of the medicine can be maintained. Another example is in the field of chemical industry, separating the mixed liquid, the membrane can also distinguish the size of molecules, divide and conquer, and help the chemical process to proceed in an orderly manner.

In addition, in the purification of water, it also has great achievements. The dust, bacteria and harmful ions in the water cannot enter the membrane when encountering this. Water seeps through, which can be used for human use or industrial needs. Its work is not great.

Cover the cellulose acetate semipermeable membrane, with exquisite fabrication, it can be used for practical work. It is an indispensable tool in various industries. It is a good example of the wisdom of the ancients and the skills of today.
