Status
In order to solve the raw material (made of refined cotton linters) inadequate sources of recent years some of our research
institutes and enterprises to work together, the comprehensive utilization of straw, foot cotton (cotton waste), tofu and
other trial production of CMC（Carboxymethyl Cellulose to be successful, greatly reduced the cost of production, such as
CMC industrial production has opened up a new source of raw material way, to achieve the comprehensive utilization of
resources. While reducing production costs, on the other hand went, higher CMC fine direction. Currently, CMC's research
and development focus primarily on the transformation of the existing production technology and manufacturing process
innovation, as well as CMC new products with unique properties, such as the successful development abroad and has
universal application "solvent - slurry" [1] technology to produce a new modified CMC with high performance and stability,
due to the higher degree of substitution, the substituents are more evenly distributed, so that it can be applied in the
broader field of industrial production and complex environment to meet the higher process Claim. International call this
new modified CMC is also called "polyanionic cellulose (abbreviated PAC, Poly anionic cellulose)".
