The high-end alternative product of sodium carboxymethyl cellulose is polyanionic cellulose (PAC), which is also an anionic cellulose ether, with higher substitution degree and substitution uniformity, shorter molecular chain and more stable molecular structure. , so it has better salt resistance, acid resistance, calcium resistance, high temperature resistance and other properties, and its solubility is also enhanced. It is used in all industries where carboxymethyl cellulose can be applied, providing better stability and meeting higher requirements. Process requirements. Carboxymethyl cellulose is a non-toxic and odorless white flocculent powder with stable performance and is easily soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, insoluble It can be used in organic solvents such as ethanol. CMC can be used as adhesive, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.
Sodium carboxymethyl cellulose is the product with the largest output, the most widely used and the most convenient use among cellulose ethers, commonly known as “industrial monosodium glutamate”.
1. It is used for drilling and digging wells of oil and natural gas.
CMC with high viscosity and high degree of substitution is suitable for mud with low density, and CMC with low viscosity and high degree of substitution is suitable for mud with high density. The selection of CMC should be determined according to different conditions such as mud type, region and well depth.
2. It is used in textile, printing and dyeing industries. The textile industry uses CMC as a sizing agent for light yarn sizing of cotton, silk wool, chemical fiber, blended and other strong materials;
3. Used in paper industry CMC can be used as paper surface smoothing agent and sizing agent in paper industry. Adding 0.1% to 0.3% CMC to the pulp can enhance the tensile strength of the paper by 40% to 50%, increase the compressive rupture by 50%, and increase the kneadability by 4 to 5 times.
4. CMC can be used as a dirt adsorbent when added to synthetic detergents; daily chemicals such as toothpaste industry CMC glycerin aqueous solution is used as a gum base for toothpaste; pharmaceutical industry is used as a thickener and emulsifier; CMC aqueous solution is thickened and used for floating mineral processing, etc.
5. It can be used as adhesive, plasticizer, suspending agent for glaze, color fixing agent, etc. in the ceramic industry.
6. Used in construction to improve water retention and strength
7. It is used in the food industry. The food industry uses CMC with a high degree of substitution as a thickener for ice cream, canned food, quick-cooked noodles, and a foam stabilizer for beer, etc. For thickeners, binders or excipients.
8. The pharmaceutical industry selects CMC with appropriate viscosity as a tablet binder, disintegrant, and suspending agent for suspensions.
