CMC(CARBOXY METHYL CELLULOSE) for oil Drilling, CMC is a low molecular weight, low viscosity type polymer designed specifically for use in solids-laden, water-based drilling fluids, which can effectively reduce the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strengths.
Description:
It is a low viscosity type polymer designed specifically for use in solids-laden, water-based drilling fluids, which can effectively reduce the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strengths.

Competitive Advantage:
1 | Economical to use - lower dosage levels. |
2 | Non-corrosive of suggested dosage, economical and effective at low levels. |
3 | Can eliminate the use of alum & further ferric salts when used as primary coagulants. |
4 | Reduction in the sludge of dewatering process system. |
5 | Faster sedimentation, better flocculation. |
6 | Non-pollution (no aluminum, chlorine, heavy metal ions etc.). |
7 | 10 years of manufacturing experience, with more than 20 technical engineers |
Functional Principle
1 | Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging and make flocculation structure enlarge and thicken, and have the functions of surface adsorption and electric neutralization. |
2 | Reinforcing Mechanism: PAM molecule chain and dispersed phase form bridging bond, ion bond, and covalent bond to increase combination strength. |
