Product description:
We are offering high quality carboxymethyl cellulose (CMC) in large quantity.The product is a free-flowing or granulated powder.It is obtained by Carboxymethylation of cellulose. Its aqueous solution has the functions of thickening, film formation, adhesion, water retention, colloid protection, emulsification and suspension. It is widely used in oil drilling fluid, food, medicine, textile and paper industries, and is one of the most important cellulose ethers.
Grade:API 13 Grade and/or OCMA,DFCP-2,DFCP-7 standard
HS Code(Tariff code):3912310000
Trade terms: FOB,CFR,CIF,FCA,CPT
Supply ability: 1000MT/month
Typical Properties of Physical and Chemical:
High-viscosity CMC (CMC-HVT):
Viscometer dial reading at 600 r/min
–in deionized water:≥ 30
– in 40 g/l salt solution:≥30
– in saturated salt water ≥ 30
Filtrate volume, millilitres ≤ 10,0
Low-viscosity CMC(CMC-LVT)
Viscometer dial reading at 600 r/min≤ 90
Filtrate volume, millilitres ≤ 10
Applications:
- In oil drilling, it is used to protect oil wells as filtrate reducer and viscosifier.
- It is also widely used in textile, printing and dyeing, paper making, feed, daily chemical, construction, ceramics, stationery pigments, metallurgical pellets, fragrance making, fertilizer, adhesives and other fields
Advantages:
1. High transparency, controllable viscosity and water loss;
2. Water-based mud suitable for fresh water, seawater and saturated brine;
3. Stabilize soft soil structure to prevent shaft wall collapse.
4. It can increase the pulp yield and reduce the filtration capacity.
5. It has excellent performance in drilling.
