■ Specifications
Features
1. First and now the largest manufacturer of sulfonated asphalt in China
2. Saudi Aramco, Baker Hughes and Halliburton's business partner
3.No any quality complaints for 12 Years
4. High degree of substitution, good uniformity of substitution.
5. High transparency, controlle viscosity and water loss.
6. Stabilize soft soil structure; prevent collapse of wall of a well.
7. Suitable for fresh water, sea water, saturated brine slurry.
8. Improve mud-making volume, reduce filtration loss.
9. Has excellent performance in oil drilling.
Description
Carboxy Methyl Cellulose is important cellulose ethers, chemically modified natural fibers are obtained after a good water-soluble polyamines compound, soluble in cold water. It has emulsifying agent, a solid dispersion, and non-perishable, physiologically harmless unusual and extremely valuable comprehensive physical and chemical properties.
Carboxy Methyl Cellulose can be widely used in petroleum drilling, having good water loss control capability. Meets APIs.
