Sodium Carboxymethyl Cellulose is a kind of hydrophilic anionic which can be used in paper making production.
Sodium CMC can replace traditional paper making auxiliary PVA (Polyvinyl Alcohol), PAM (Polyacrylamide), and modified starch or be used with them.
Along with the development of technology, various types of paper making auxiliary were developed, and the new paper making technology requires more effective and environmental auxiliary nowadays. Sodium Carboxymethyl Cellulose is a kind of effective and environmental paper making auxiliary which will bring fewer troubles with WWTP because the BOD: COD is more than 40%. WWTP can do sewage treatment by biodegradation which is much easier and economical.
The advantages and properties of our paper making grade Sodium CMC:
- Sodium CMC can be used as wet-end additive to increase paper strength, like tissue paper, napkin paper, board paper, etc.
The dosage is about 0.4%-0.8% of total paper pulping which can improve paper strength by 30%-50%. If mixed with PAM, the function will be better and synergy effect will take place.
- Sodium CMC can also be used as a sizing agent in coated paper, heat transfer paper, and other high standard paper. It has excellent film-forming performance and water retention properties that can keep uniform coating and sizing. Water retention property will be improved a lot if using mixed with modified starch.
- Sodium CMC can satisfy various coating speeds from 300-2000/min and keep coating uniformly, especially for higher coating speed (above1000m/min). As modern paper making technology all are high coating speed, Sodium CMC is the best option. High purity and high Degree of Substitution (D.S), low viscosity Sodium CMC will bring you unexpected coated paper quality.
