Functional Properties of CMC (Carboxymethyl Cellulose)
Carboxymethyl cellulose (sodium carboxyme thyl cellulose, CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, and is the most important ionic cellulose gum. CMC is usually an anionic polymer compound prepared by reacting natural cellulose with caustic alkali and mono...Read more -
Application of Carboxymethyl Cellulose in Food Industry
Carboxymethylcellulose (CMC) is synthesized from fibers (fly/short lint, pulp, etc.), sodium hydroxide, and monochloroacetic acid. According to different uses, CMC has three specifications: pure product purity ≥ 97%, industrial product purity 70-80%, crude product purity 50-60%. CMC has excellent...Read more -
Quality Identification of Hydroxypropyl Methyl Cellulose
The difference between adulterated hydroxypropyl methylcellulose (HPMC) and pure hydroxypropyl methylcellulose (HPMC) 1. Appearance: Pure hydroxypropyl methylcellulose HPMC looks fluffy and has a low bulk density, ranging from 0.3-0.4g/ml; adulterated hydroxypropyl methylcellulose HPMC has better...Read more -
What is the appropriate viscosity of hydroxypropyl methylcellulose?
Putty powder is generally 100,000 yuan, and the requirements for mortar are higher, and 150,000 yuan is required for easy use. Moreover, the most important function of HPMC is water retention, followed by thickening. In the putty powder, as long as the water retention is good and the viscosity is...Read more -
