What is the production process of Cellulose Acetate?

The production process of cellulose and acetate, although the name was not heard in ancient times, but the current process also has its own method to follow. From the beginning, natural cellulose is taken, often derived from wood pulp, cotton lint and other materials. This cellulose has a tough texture and a special molecular structure. First, it is treated with chemical agents to make it swell and break its original structural constraints for subsequent reactions. Next, acetic anhydride is introduced, supplemented by a catalyst, usually sulfuric acid, etc. The acetic anhydride and cellulose molecules undergo an esterification reaction. This reaction is delicate. The acetyl group of acetic anhydride is combined with the hydroxyl group of cellulose to form a new compound, cellulose acetate. When reacting, the temperature, time and the proportion of agent are all important. If the temperature is too high, the reaction will be too fast and the product may be uneven; if it is too low, the reaction will be slow and time-consuming. The control of time depends on the degree of reaction. If it takes a long time, it will be over-esterified, and if it is short, it will be under-esterified. And the environment of the reaction system should not be ignored. It must be dispersed evenly in a suitable solvent to make the reaction sufficient. After precipitation and filtration, the crude product is obtained. Then it is washed and dried to remove its impurities and improve its purity. Dried product, or in the form of granules or powders. Depending on its use, it can be made into fibers, films, and other shapes by melt spinning, solution film forming, etc., to meet the needs of textile, packaging, and optical materials industries. The production process of cellulose and acetate is interconnected, and it is very delicate. It all depends on today's chemical technology to make natural things coincide with chemical reagents and make new materials to meet all kinds of world uses.

What are the precautions for using Cellulose Acetate?

For cellulose and acetate, many things should be paid attention to when using it. The most important one is its scope of application. Although cellulose acetate has a wide range of uses, it is suitable for different categories. For example, in the textile field, some fabrics are made with it, which is soft to the touch and has a unique luster. However, in a strong acid-base environment, its performance may be damaged. Therefore, when it is used, it is necessary to clarify its application scene and do not place it in an improper environment. Furthermore, the influence of temperature and humidity. These two have a great impact on the performance of cellulose acetate. Under high temperature, it may soften and deform, and if the humidity is too high, it is easy to be damp, resulting in a decrease in mechanical properties. If the book is packed with this material, it should be stored in a dry and cool place to avoid damage to the book. In addition, cleaning and maintenance should not be neglected. When cleaning, appropriate detergents should be selected to avoid the use of strong irritants to prevent erosion of the surface of the material.
