In the mineral processing process, Mud Stabilizer CMC (CMC-Na) is a high molecular compound that maintains the stability and fluidity of mud by adjusting the rheology of mud, inhibiting particle sedimentation and dispersion. CMC Cellulose often used as a stabilizer and rheology regulator for mud (ore pulp). With its Tykkelse, sprednings- og hævelsesinhiberingsegenskaber, det er en økonomisk og effektiv mudderstabilisator .
Hovedapplikationer
-
1. fortykning og ophængsstabilitet
Mud Stabilizer CMC could form a viscous solution after dissolving in water. It increases the viscosity of the slurry, slows down the sedimentation rate of solid particles, maintains the uniform suspension of mineral particles in the slurry, prevents stratification or pipe blockage, and ensures the normal flotation of minerals.

2. inhiberer udvidelse af ler
In ores containing clay minerals, Mud Stabilizer CMC can reduce the hydrophobicity of the mineral surface, so that magnesium-containing silicate gangue minerals such as talc, chlorite, and serpentine are inhibited. CMC-Na can inhibit its hydration expansion and reduce abnormal fluctuations in slurry viscosity by adsorbing on the surface of clay particles. In addition, it also has an inhibitory effect on minerals such as pyrite. When the pH is greater than 11, the surface of pyrite is oxidized to form a hydrophilic iron hydroxide film, and the recovery rate decreases. The addition of sodium carboxymethyl cellulose can eliminate the inhibitory effect of Serpentin på pyrite .

3. spredningseffekt
Mud Stabilizer CMC can adjust the surface electrical properties of minerals. Through electrostatic repulsion and steric hindrance effects, it can disperse minerals (such as serpentine and pyrite) that are heterogeneously condensed due to electrostatic effects, prevent fine-grained minerals from agglomerating, and improve separation efficiency (such as flotation or magnetic separation processer) . I montmorillonit-systemet øger natriumcarboxymethylcellulose ladningsantallet af montmorillonitpartikler gennem en bestemt adsorptionsmetode, øger partiklernes dobbeltlagspotentiale og forbedrer systemets spredningsydelse .

Oversigt
Mud stabilizer CMC is an indispensable chemical additive in mining, oil, gas and geothermal drilling, which can effectively improve the stability and rheological properties of drilling mud. It increases the viscosity of the mud to ensure that the drill cuttings can be fully suspended and prevent well wall collapse, thereby ensuring the smooth progress of drilling operations. In Derudover kan CMC -cellulose forbedre smøringen af mudder, reducere borebitslitage og forbedre boreeffektiviteten .
