Now there is a technique to say: Take the cellulose acetate method as the key, study its principles in detail, and do it properly.

Start by preparing cellulose, which is the basis. Take an appropriate amount of cellulose, process it with precision, remove its impurities, and store it pure, so that it can be used with high quality.

Then add acetic anhydride and other agents in sequence. Under appropriate temperature and pressure, make it phase. In the meantime, keep an eye on the change of temperature and the degree of pressure control, so that the reaction can proceed smoothly. If the temperature is too high, it may change its nature; if the pressure is not appropriate, it will also hinder its formation.

After the reaction is completed, separate the product by a delicate method. It can be filtered or precipitated to remove the unsuitable agent to obtain a pure cellulose acetate.

After that, it can be processed according to its use. Or making membranes, or making silk, all according to need. Its weight is light and strong, its performance is stable and good, and it can be used in all industries.

The cellulose acetate method is rigorous in the process, and every step is about success or failure. If you make good use of this technique, you can get good products and benefit from many fields.
