PolyanionicCellulose (PAC) Introduction: Polyanionic cellulose, abbreviated as PAC.It is a water-soluble polymer derived from cellulose. It would be more accurate to say polyanionic cellulose is a water-soluble cellulose ether chemically modified from natural cellulose.. The appearance of poly anionic cellulose is white and light yellow powder or particle.
PolyanionicCellulose is more suitable for offshore drilling and the functions of Polyanionic Cellulose in drilling fluid are listed as below. 1). The drilling mud is the suspended matter of solids in the aqueous solution, and the same as other colloidal suspension dispersions, so has a certain life period.
A small amount of Polyanionic Cellulose can replace a lot of clay and this kind of mud can reduce the difficulties resulting from encountering CaSO42H20 or CaSO4 salt belt during drilling process. However, PAC applies to the mud with larger proportion, can reduce the fluid loss but have little effect on the viscosity. In use, Polyanionic
Polyanioniccellulose regular grade (PAC R or PAC HV) is a premium grade modified cellulose with high viscosity and high molecular weight which can be used as a viscosifier and fluid loss control additive in water-based drilling mud systems.PAC R can provide excellent viscosity and reduce API filtration rate for oil well drilling fluids.API 13A and OCMA grades polyanionic cellulose (pac) in
AquaPAC™ polyanionic cellulose is of premium quality and cost-effective and provides outstanding fluid-loss control properties, shale inhibition and salt tolerance. It is useful for water-based drilling fluids as well as in low-density brines.
PolyanionicCellulose (PAC) CAS No.: 9004-32-4. Molecular Formular: [C 6 H 7 O 2 (OH) 2 CH 2 COONa] n. Structural Formular: Property: PAC is a kind of nonionic cellulose ether featured the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are demi-natural polymer additive, thickening agent
Polyanioniccellulose(PAC) - ProchemieCharacteristics : Polyanioniccellulose(PAC) is Ionic cellulose ether is a high purity, high degree of substitution, substituent distribution and so on. PAC low viscosity-type filtration can effectively reduce the volume of the system without a PAC / Polyanionic Cellulose / Drilling Mud Additive / Fluid Control Agent…
PAC is an indispensable product for drilling mud making. It is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, PAC dissolves immediately in cold/hot water and can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and
PAC HV is a high quality Polyanionic Cellulose Polymer. It is a water based filtration control agent which also provides viscosity and controls fluid loss. Application: PAC HV is a cost effective means of controlling fluid loss and increasing viscosity and it improves the quality of the filter cake in water based drilling systems.
PolyanionicCellulosePolymer (PAC) is used for Oil Well Drilling to give suitable flow properties to the drilling muds.PAC also improves the water retention of muds and prevents excessive penetration of drilling liquid into the immediate surroundings. PAC can be added to control filtration of water-base muds without a severe increase in the
DESCRIPTION OF PAC POLYANIONIC CELLULOSE. PAC Polyanionic cellulose a substance which can be added to drilling muds, counting on the intended application and desired properties of the mud include detergents, foaming agents, defoaming agents.Having fluid-loss control , shale inhibition and salt tolerance. It is useful for water-based drilling fluids as well as in low-density brines, for one or
PolyanionicCellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. And it is an important water-soluble cellulose ether. The appearance is the white or light yellow powder or granules. Non-toxic and tasteless, strong hygroscopicity, easily soluble in cold water, and hot water.

PAC LV is white or light yellow free flowing powder, whose aqueous solution is clear and sticky. As a water-soluble polymer, PAC LV can be dissolved in the cold or hot water quickly. Bichain is one of reliable low viscosity polyanionic cellulose suppliers and manufacturers for the filtration control of drilling fluids at low PAC prices.
Water-based drilling fluid additive Polyanionic Cellulose Pac HV. PAC HV PLUS is high molecular weight,high viscosity polymer for water-based drilling fluids,which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid
Some of the fluid loss control additives include starch, hydroxypropyl starch, mixtures of starch and polyanionic cellulose (PAC), and carboxymethyl cellulose (CMC). The use of natural polymers for oil field operations can be traced back to the 1930s. More natural polymers have been investigated in recent years for drilling fluid applications.
