Sodium carboxymethylcellulose (CMC)

It is a major cationic cellulose derivative that widely use in the food industry. The solution of CMC is pseudoplastic, and the main parameters of CMC structure (relative molecular mass and substitution degree) and content of C M C harm the liquidity transition. The study found that when the CMC concentration value is too low. The actual effect of CMC with different technical parameters is different on smooth acid and alkaline milk drinks. The CMC with high substitution degree is beneficial to the reliability of the system software.

Manufacturing method 1: Cellulose is the world’s most colorful pure natural polymer chemicals. Its raw materials come from wood, cotton wool, cotton short-staple wool, straw, wheat grass, reed leaf. Opium poppy flower, mulberry peel, bagasse and so on. Because of the lack of natural resources, 70% of China’s cellulose raw materials come from non-wood network resources. In China, the average cellulose composition of conifer raw material the average cellulose composition of grass stem is about 40%.

Manufacturing method 2: the fiber plant raw materials and strong oxidant mashed into slurry, make a-cellulose, then the cellulose to solve, as a part of the melting polymer, and then remove the part of the crystallization and purification treatment.

Manufacturing mode 3: put the selected industrial production wooden paddle board into the reaction tank with an ambient temperature of 90~100℃, and the hydrolysis reaction time is 0.5~2 hours, and then send to the reaction tank with 10%~10% sulfuric acid reflection amount of 5%~10%) for heating hydrolysis reaction. After the reflection is complete, refrigeration is sent to the middle tank, with alkali to neutral. After consideration, the mud was dry at 80~100℃, and eventually crushed the goods.

Manufacturing mode 4: the cellulose is of wooden paddle or cotton wool pulp. Bleach and mechanical equipment dispersion is specially. Under some standard, cellulose is with water. During the chemical reaction, the oxygen bridge breaks up, the water is, and the cellulose changes from the long-chain molecular structure to the satchel molecular structure, until the oxygen bridge all breaks up and becomes the glucose water.
