Hydroxypropyl methylcellulose (CMC) is a non-toxic, colorless and odorless milky white precipitate powder with stable characteristics and can dissolve strong electrolytes. The solution is a masculine or alkaline transparent viscous liquid, which can dissolve other hydrosols and epoxy resin glues, but does not dissolve organic solvents such as ethanol. CMC can be used as adhesive, thickener, granule, desulfurizer, thickening agent, thickening agent, sizing agent, etc. Hydroxypropylmethylcellulosesodium (CMC) is a product with the largest total output, wide application range, and easy use among cellulose ethers. It is also known as “industrial production of MSG”.
1. Use For oil and gas exploration, well digging and other construction projects
1.Included CMC’s slurry can produce thin, hard, low water absorption anaerobic granular sludge in the well chamber, reducing the water flow rate.
2. In After adding CMC to the mud, the drilling machine can obtain a low initial shear force, which is conducive to releasing the gas trapped in the mud, and at the same time, the debris is quickly discarded in the puddle.
3. Exploration Slurry, like other suspended dispersions, has a certain shelf life. Adding CMC can stabilize it and increase its shelf life.
4. Contains CMC slurry is rarely harmed by Aspergillus flavus, so there is no need to maintain a high pH value or use preservatives.
5.Included CMC is used as a modified material for exploration mud cleaning fluid, which can resist the pollution of various soluble salts.
6.Included CMC’s mud is reliable and can still reduce water content even if the temperature is above 150°C.
CMC with high viscosity and high degree of substitution is suitable for mud with low density, while CMC with low viscosity and high degree of substitution is suitable for mud with high density. The selection of CMC should be decided according to different standards such as mud type, location, and depth.
2. Used in the industrial production of textile products and paper mills. The textile industry uses CMC as a sizing agent for strong materials such as cotton, silk wool, man-made fibers, and blended fabrics. Transparent tulle sizing;
3. Used in the paper industry CMC can be used as a printing paper polish and sizing agent in the paper industry. Adding CMC to the paper pulp can increase the resistance of printing paper by 40% to 50%, increase the tensile strength and cracking resistance by 50%, and expand the flexibility by 4 to 5 times.
4. CMC can be used as a dirt adsorbent in metal cutting fluids; analytical chemistry of daily necessities such as industrial production of tooth cleaning powder, CMC’s glycerin solution can be used as the gum base of tooth cleaning powder ; Pharmaceutical industry as thickener and desulfurizer; CMC solution thickened and used as flotation mineral processing, etc.
5. Use In ceramic art, it can be used as adhesive, ductility agent, glaze granules, color-fixing agent, etc. for blanks.
6. Use Used in construction projects to improve water retention and tensile strength
7. Used in the food industry. The food industry uses high displacement CMC for ice cream, Thickeners for canned food, instant noodles, plastic foam thickeners for red wine, etc., used as thickeners, binders or shape-forming agents in the production of apple jam, sugar juice, sherbet, small desserts, ice cream health drinks, etc. agent.
8. Use appropriate viscosity in biomedicineCMC is used as a bulk binder, disintegrant, and suspending agent for suspensions.
