Carboxymethyl cellulose can form high-viscosity colloids, adhesives, thickening, emulsification and dispersion, water retention, and film forming. It is resistant to acid, salt, and turbidity, and is physiologically harmless. It is widely used in food, medicine, daily chemical, petroleum, paper, textile, construction and other fields.
Sodium carboxymethyl cellulose (CMC) is the product with the largest output, the most versatile and the most convenient use among cellulose ethers, commonly known as "industrial monosodium glutamate".
When the carboxymethyl cellulose product is added directly to water, it will condense and then dissolve. There are three dissolution methods, and users can choose the most convenient method according to the usage:
1. Hot water method:
1) Put the required hot water into the container and heat it to about 70°C. After slow stirring, gradually add carboxymethyl cellulose to make the carboxymethyl cellulose float on the water surface, and then cool into cement slurry under stirring.
2) Add the required water 1≤3 or 2≤3 into the container, heat it to 70°C, disperse the heat of carboxymethyl cellulose, and then add the remaining cold water or ice water to the hot water slurry and stir to cool.
2. Powder mixing method:
carboxymethyl cellulose powder particles and the same amount or a large amount of other powder ingredients are completely dispersed by dry mixing, and then dissolved by adding water.
3. Organic solvent wetting method:
disperse or wet the carboxymethyl cellulose with organic solvents such as ethanol, ethylene glycol or oil, and then dissolve the carboxymethyl cellulose with water to dissolve the carboxymethyl cellulose smoothly.
