Carboxymethyl cellulose (CMC) -------------------------------------------------------------------------------- Product introduction: CMC is using natural cellulose was a kind of high purity, refined cellulose ether.Product appearance is white powder, dissolving, high light transmittance, has better rheological properties and thixotropic properties.Main chemical reaction is alkali cellulose quaternization generated by cellulose and alkali and alkali cellulose and the etherification reaction of chloroacetic acid. Product physical condition: Carboxymethyl cellulose (CMC) anionic cellulose ethers, appearance for white or light yellow powder or flocculent fibers white powder, odorless, non-toxic;Soluble in cold water or hot water, the formation has certain viscosity of transparent solution.For neutral or slightly alkaline solution, insoluble in ethanol, ethyl ether, isopropyl alcohol, acetone and other organic solvent, can dissolve in water cut of 60% ethanol or acetone solution.Has the water absorbability, the thermal stability, viscosity decreases with temperature rise, and the solution at PH 2 ~ 10 stability, PH less than 2, have a solid precipitation, viscosity lower PH value is higher than 10.Color temperature 227 ℃, carbonization temperature 227 ℃, 2% aqueous solution surface tension 71 mn/n. Product use: 1, used in oil and gas drilling, digging Wells and other projects. 2, used in textile, printing and dyeing industry textile industry will CMC as sizing agent, used for cotton, silk, chemical fiber, blending and strong fine gauze sizing. 3, used in the papermaking industry CMC in paper industry for paper smoothing agent, sizing agent.Add 0.1% ~ 0.3% of CMC in pulp can make paper strength 40% ~ 50% resistance to tension, compression fracture degree is increased by 50%, and increase 4 ~ 5 times. 4, CMC add dirt can be used as adsorbent in synthetic detergent;Glycerin, daily chemical, such as toothpaste industry CMC aqueous solution used as toothpaste gel base;Pharmaceutical industry used as thickener and emulsifier;CMC aqueous solution viscosity after used for flotation and so on. 5, can be used in ceramic industry blank of adhesive, plasticizer, glaze suspending agent, fixing agent, etc. 6, used in construction, improve the water retention and strength.
