CMC Cellulose and Its Structure Characterization
CMC Cellulose and Its Structure Characterization Using straw cellulose as raw material, it was modified by etherification. Through the single factor and rotation test, the optimal conditions for the preparation of carboxymethyl cellulose were determined to be: etherification time 100min, etherifi...Read more -
What are the properties of methylcellulose?
1. It can be melted when heated above 200°C, and the ash content is about 0.5% when burned, and it is neutral after being made into a slurry with water. As for its viscosity, it depends on its degree of polymerization. 2. Solubility in water is inversely proportional to temperature, high temperat...Read more -

Carboxymethyl cellulose reinforced
Carboxymethyl cellulose (Carboxy Methyl Cellulose, CMC) is an ether derivative of natural cellulose. It is white or slightly yellow powder. It is a water-soluble anionic surfactant. It is odorless, tasteless, non-toxic, and has excellent water solubility. , Viscosity, emulsification, diffusion, e...Read more -
Sodium carboxymethyl cellulose CMC physical and chemical properties
1. hygroscopicity Carboxymethylcellulose sodium CMC has the same water absorption as other water-soluble glues. Its humidity balance increases with the increase of humidity and decreases with the increase of temperature. The higher the D.S, the greater the air humidity, and the product’s The str...Read more -
Application of hydroxypropyl cellulose in solid preparation
Hydroxypropyl cellulose, a pharmaceutical excipient, is divided into low-substituted hydroxypropyl cellulose (L-HPC) and high-substituted hydroxypropyl cellulose (H-HPC) according to the content of its substituent hydroxypropoxyl group. L-HPC swells into a colloidal solution in water, has the pro...Read more -
Properties of Cationic Cellulose Ether Solution
Properties of Cationic Cellulose Ether Solution The dilute solution properties of a high-charge-density cationic cellulose ether (KG-30M) at different pH values were studied with a laser scattering instrument, from the hydrodynamic radius (Rh) at different angles, and the root mean square radius ...Read more -
What is the viscosity of hydroxypropyl methylcellulose hpmc?
What is the viscosity of hydroxypropyl methylcellulose hpmc? Putty powder for interior walls generally has a viscosity of 100,000. The cement mortar has higher requirements for adjustment, and the viscosity of 150,000 is easy to use. In addition, the most critical role of HPMC is to lock water, f...Read more -
Instant type hydroxypropyl methylcellulose
Instant type hydroxypropyl methylcellulose 1. The water content is too high, resulting in too low content, which is equivalent to reducing the concentration of the solution. 2. The viscosity is low, and some marked viscosity does not match the actual viscosity. 3. Stir even after adding the ingre...Read more -
