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.
Specifications:
1) Technical grade sodium carboxy methyl cellulose used for oil drilling,
geological prospecting and natural gas extract mine
2) Anti-salt, anti-high-temperature
3) No-toxic
4) Increase the viscosity of the mud and can control the mud fluid loss
5) Appearance: free-flowing off-white powder
6) Moisture content: 10.0% (max.)
7) PH of solution: 6.0 - 8.5
8) Particle size: 95% (min.)
9) Passes through 40 meshes
10) Mud performance properties 600r/m reading value

c) 2.5g in 350ml saturated navl: ≥30
| APPLICATION FIELDS: | • Petroleum and Gas Field: -Drilling fluids, EOR, Profile Modification, Fluid loss control, Lubrication, Shale Stabilization |
Physical Properties:
| Appearance | Free-flowing off-white powder |
| Moisture Content | 8%max. |
| Degree of Substitution | 0.80min. |
| PH of 1% Solution | 6.0-8.5 |
| Particle size | 95%min.pass through 40 mesh |
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. |
Package and Storage:
- Packed in Kraft or PE bags with inner plastic bags, with each bag containing 25kgs, or 750kgs net big bag.
- Stored in the original packaging in a cool and dry place, away from sources of heat, flame, and direct sunlight.
