Polyanionic Cellulose (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.
Polyanionic Cellulose 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.
These products are demi-natural polymer additive, thickening agent, filtrate reducer. Polyanionic Cellulose (PAC) is an indispensable product for drilling mud making. Polyanionic Cellulose (PAC) is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, it dissolves immediately in cold
6. Environment friendly PAC LV HV R Drilling Fluid Mud Polyanionic Cellulose Polymer Applications in Drilling Fluid 1. Protect the wall of oil well, prevent mud flowing away and carry crumbs. 2. Protect drilling bit and increase drilling speed. 3.
Polyanionic Cellulose (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.
Polyanionic Cellulose (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
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.
Polyanionic cellulose 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
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
2.PAC. Landoil PAC is a polyanionic cellulose polymer, which is an extremely effective filtrate reducer in fresh or salty water. It also acts as a thinner in salty water in low concentrations. Application. Landoil PAC can be used in any type of water based drilling fluid, including saturated salt water fluids.
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, filtrate reducer. PAC is an indispensable product for drilling mud making.
pac is a cellulose derivative product, white to creamish coloured free flowing fine powder / granules available as pac- lv and pac-r. pac -lv is a short chain polymer and it is used as a filtration control agent in all types of water base drilling mud. pac-r is a long chain polymer of high molecular weight, readily
