Carboxymethyl Cellulose Sodium Salt
Natural cellulose is the most widely distributed and abundant polysaccharide in nature, and its sources are very rich. At present, the modification technologies of cellulose mainly focus on etherification and esterification. Carboxymethylation reaction is a type of etherification technology. Carboxymethyl cellulose (CMC) is obtained after carboxymethylation of cellulose. Its aqueous solution has functions such as thickening, film-forming, bonding, moisture retention, colloid protection, emulsification and suspension. It is widely used in industries such as petroleum, food, medicine, textile and papermaking .
Compared with other types of cellulose derivatives, CMC has significant advantages in the following aspects: moderate cost, stable performance, wide applicability can be used with a variety of organic and inorganic compatibility of green environmental protection, biodegradable, conform to the trend of contemporary environmental protection .
Understanding the essence and applications of carboxymethyl cellulose not only helps with correct selection but also facilitates the optimization of formulas, cost reduction and improvement of product performance in practical use. It is a truly versatile material, possessing strong vitality in both traditional industries and emerging fields.
(1) of carboxymethyl cellulose hygroscopicity is larger, general storage condition can contain water.
(2), carboxymethyl cellulose solution won't produce gel viscosity with temperature drop, the temperature of more than 50 ℃, the viscosity is not reversible.
(3) its stability are greatly influenced by pH. It is generally applicable in gypsum-based mortar but not in cement-based mortar. It will lose viscosity at high alkalinity. Its water retention is far lower than that of methylcellulose. It has a retarding effect on gypsum-based mortar and reduces its strength. However, the price of carboxymethyl cellulose is significantly lower than that of methyl cellulose. This is hydroxypropyl methyl cellulose, carboxymethyl cellulose.
