[0002] Cellulose ether is the general name of a series of products formed by the reaction of alkali cellulose and etherifying agent under certain conditions. It is a high-molecular compound with an ether structure made from cellulose. China is the world's largest producer and consumer of cellulose ether. In the process of manufacturing cellulose ether, it is usually necessary to dry the cellulose ether to make it into a powder for easy use.
