What is the role of methyl cellulose?

original title: What is the role of methyl celluloseof methyl cellulose (CMC) is a non-toxic odorless white floc-like powder, stable performance, soluble in water, its water solution is neutral or alkaline transparent viscous liquid, soluble in other water-soluble glues and resins, insoluble in ethanol and other organic solvents. CMC can be used as an adhesive, thickener, suspension, emulsifier, dispersant, stabilizer, slurry, etc. Sodium methylene cellulose (CMC) is the largest, most widely used and most convenient product in cellulose ether, commonly known as "industrial MSG".. For oil and natural gas drilling, drilling and other projects 1. Mud containing CMC can make the well wall form thin and firm, low permeability filter cake, so that the loss of water is reduced.. 2. After adding CMC to the mud, the drilling rig can get a low initial cut force, so that the mud is easy to release the gas wrapped in it, and the debris is quickly abandoned in the mud pit.. 3. Drilling mud and other suspended dispersions, like a certain period of existence, after adding CMC can make it stable and extend the existence period.. 4. Mud containing CMC is rarely affected by mold, so there is no need to maintain a high pH value, nor do you need to use preservatives.. 5. Contains CMC as a drilling mud washing well liquid treatment agent, can resist a variety of soluble salt pollution.. 6. Mud with CMC, stable, even if the temperature is above 150 degrees C can reduce water loss.high viscosity, high substitution degree CMC is suitable for less dense mud, low viscosity high replacement degree CMC is suitable for dense mud. The selection of CMC should be determined according to the type of mud and the region, well depth and other different conditions., for the textile, printing and dyeing industry Textile industry CMC as a pulping agent, used in cotton, silk, chemical fiber, blending and other strong materials of light yarn pulp ; Adding 0.1% to 0.3% CMC to pulp can make the paper increase the anti-tension by 40% to 50%, increase the anti-pressure rupture by 50%, and increase the kneave by 4 to 5 times.4. CMC added to the synthetic detergent can be used as a dirt adsorbent, daily chemicals such as toothpaste industry CMC glycerin solution as a glue base for toothpaste, pharmaceutical industry as a thickener and emulsifier, CMC water solution added to the adhesive and used as a floating water processing.V. For use in the ceramic industry can do blank adhesives, plasticizers, glaze suspensions, solidcolor agents and so on., for construction, improve water retention and strength seven, for the food industry, the food industry uses high displacement CMC for ice cream, canned, quick-boiled surface thickener, beer foam stabilizer, etc. , in the processing of jam, sugar juice, fruit dew, snacks, ice cream drinks as thickeners, adhesives or shape agents.eight, the pharmaceutical industry to choose the appropriate viscosity CMC as a tablet adhesive, disaconic agent, suspension agent, etc.extensionthe high-end alternative products of methyl cellulose (CMC) is also an anionized cellulose ether, with higher replacement and replacement uniformity, shorter molecular chain, more stable molecular structure, so with better anti-salt, acid, calcium, high temperature and other properties, so so that solubility is also enhanced. Applications in all industries where methyl cellulose (CMC) can be used provide better stability and meet higher process requirements.
