Easy-Bore TM a co-polymer of anionic character having high molecular weight. A water soluble polymer which is primarily used as a efficient fluid loss reducer and viscosifier. An effective colloid for shales and cutting in fresh water, calcium, sodium brines and KCL mud systems.
PHPA Polymer Concentration Test Kit - FANN®
The Fann PHPA Polymer Concentration Test Kit selectively determines the concentration of PHPA (partially hydrolyzed Polyacrylamide) through a simple analytical field test utilizing a Kjeldahl procedure, modified by Fann. As hydrolysis of the polymer occurs, ammonia is released and collected on boric acid.

Xanthan behaviour in water-based drilling fluids
Polymer Degradation and Stability 38 (1992) 155-164 Xanthan behaviour in water-based drilling fluids Wenbing Xie & Jacqueline Lecourtier* Institut Fran~ais du P~trole, 1 & 4, Avenue Bois Pr~au, 92500 Rueil-Malmaison, France (Received 5 August 1991; accepted 19 August 1991) As there is a need for drilling fluid stability under high salinity conditions, the rigid polyelectrolyte xanthan was
Piles in Chalk at Norwich, Norfolk. Corbet et al. reported what is possibly the first documented use of polymer fluids for the construction of bored piles.The site was the A47 Norwich Bypass in Norfolk, where the ground conditions consisted of 5 m of peat overlying 4 m of sand and gravel and then a very thick layer of weathered chalk.

On the basis of the test results, the authors proposed a simple power–law relationship to fit the viscosity results over a range of polymer concentrations, as follows μ = 8 ⋅ 017 c 2 ⋅ 715 where μ is the apparent viscosity in mPa s and c is the concentration in per cent by weight.However, this equation has the shortcoming that the predicted viscosity will be zero if the polymer

- What is polyaluminum chloride (PAC)?
- Sci.882 012014DOI 10.1088/1755-1315/882/1/012014 Polyaluminum chloride (PAC) is commonly used as a chemical in the water treatment industry, deodorant and paper-making. The PAC is a complex inorganic substance between hydroxyl and aluminum ions that gradually takes place chlorination with its general formula of Al x (OH) y Cl 3x-y.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- Can PAC be prepared from aluminum chloride solution?
- PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [ 16, 21 ], sodium hydroxide [ , , ] and sodium aluminate [ 25 ].
