CarboxyMethylCellulose CMC OilDrilling Grade

Carboxymethyl Cellulose Sodium (CMC)-Oil Drilling Grade CAS No.: 9000-11-7 Molecular Formula:  [C6H7O2(OH)2CH2COONa]n  Structural Formula:   Property: CMC is a cellulose derivative obtained by chemically modificating the natural cellulose. It is one of the most important water soluble polymers with many advantages that other natural or synthetic glues do not have. CMC is white and flowing fine powder, which is tasteless, smelless, mould-proof, non-toxic, non-flammable and easily dissolved in water to become transparent viscose solution. Its solution has good properties of thickening, adhering, emulsifying, and stabilizing. membrane forming, moisture-holding, shape-holding, dispersing and anti-enzyme. The solution of CMC can be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic gum, pectin, xanthic gum and dissolvable starch.Specification: Physical specification of CMC for Oil drilling liquids & Oil drilling liquids properties (According to SY5093-92) LV-CMC MV-CMC HV-CMC AppearanceWhite or light yellow powder, freely flowable.Water≤10%CMC ≥80.0%≥85.0%≥95.0%Substitution degree≥0.80≥0.65≥0.8pH7.0-9.07.0-9.06.5-8.0TypeItemTypical measured valuesDistilled waterBrineSaturated brineBase mudFiltration loss,60±10ml90±10ml100±10mlApparent viscosity,≤6mPa·s≤6mPa·s≤10mPa·spH8.0±1.08.0±1.07.5±1.0HV-CMC Mud generating capacity≥200m3/t≥150m3/t≥160m3/tLV-CMC Filtration loss=10mlAddition rate,≤7.0g/l≤10.0g/lApparent viscosity≤4.0mPa·s≤6.0 mPa·sMV-CMC Addition rate6.0g/l14.0g/l3.5 g/lApparent viscosity≥15mPa.s≥15mPa.s≥15mPa.sFiltration loss≤9ml≤9ml≤8mlTechnical Specification of CMC for oil drilling liquids (According to GB/T5005-2001 or API)Type  Specification CMC-HVTViscometer      600r/minDistilled water≥30.040g/dm3 brine≥30.0Saturated brine≥30.0Filtration loss≤10.0mlCMC-LVTViscometer 600r/min≤90.0Filtration loss (ml)≤10.0Note:We could arrange product according to customer's specification Usage: CMC Oil Drilling Grade used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency. CMC has the following characteristics:  · Excellent water retention even at low concentration.  · Excellent thickening effect.  · Good resistance to salt and temperature change.  · Imparts excellent rheological property.Package and Storage: Packed in multiply paper bags or fiber drums (25KG), or as per customer requirement; keep dryKey Words: sodium carboxymethyl cellulose, CMC, CMC-Na, CM-cellulose, carboxymethyl cellulosec carboxymethyl cellulose ether
