CMC HV/CMC LV/PAC LV/PAC HV/PAC R-Oil Drilling Grade

CMC and PAC can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; also in fracturing fluid, it is used to carry stuffing and avoid fluid loss. Our product can meet API 13A, or we can produce according to customer’s requirement.
  • Commodity name: CMC HV/CMC LV/PAC LV/PAC HV/PAC R-Oil Drilling Grade
  • 数字序号: 01

Classification

Commodity Name: Polyanionic Cellulose;Sodium Carboxymethyl Cellulose

CAS No.: 【9004-32-4】

Synonyms/Type: PAC LV;PAC R;PAC HV;CMC HV;CMC LV

HS Code: 39123100

Application: Oil Drilling Industry

 

PAC(Polyanionic cellulose) and CMC (Carboxymethyl cellulose) are used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs, and the function of cleaning drilling crumbs, stabilizing of well wall, preventing the mud from flowing away, protecting drilling bit and reducing the thickness of mud cake, but while in the completion fluids, it functions to control the fluid viscosity, suspend the heavy objects, bring the filler and avoid the fluids loss. It also can replace guar gum in fracturing fluids.

CMC-Mining Grade

CMC is used in mining industry as pellet binder and flotation inhibitor. CMC is a component of the binder for mineral dust shaping and meanwhile the binder is an indispensable ingredient for pellet production. It can improve the properties of wet pellet, dry pellet and calcinated pellet. Due to its good binding property and pellet forming property, the green pellet with CMC has excellent antiknock performance, high compressive strength and dropping resistance. It can also increase the grade of pellet. CMC is an adjusting agent in floating selection process, it is used as the silicate gangue inhibitor, controlling the lead in the separation process of copper and lead, sometimes it is used as dispersant for mineral mud.

CMC-Paper making Grade

CMC(sodium carboxymethyl cellulose) displays many excellent performance in paper-making technology. it is higher valued by the majority of paper engineers and is widely used in the production of paper and paperboard, such as paper and paperboard coating process, coating rheology modifier, water - retention agent, film-forming agent, auxiliary adhesives, wet end retention enhancers and surface sizing agents, grinding aids, filler modifier and the flocculating agent which used in waste water treatment etc. We have different paper making grades of CMC to meet the different customers’ requirements.

CMC-Ceramics Grade

CMC(Carboxymethyl cellulose) is good agent used in Ceramic green body,glaze pulp,ceramic decalcomania and ceramic penetration glaze.CMC can make the glaze smoothly and improve the quality of glazed surface through its bonding, water-retaining, suspending performance. CMC can enhance the clay materials plasticity, improve the body shape, multiply green-pressing strength, reduce the breakage greatly. As an efficient body enhancer, it is no residue after burning, no side effects, and added less quantity compared with other enhancers.
