The importance of the viscosity and molecular weight for polyacrylamide
Come to talk about "the importance of the viscosity of polyacrylamide." Usually we talk about viscosity, it refers to a certain concentration and viscosity temperature. Since PAM classification there are many specifications for differe
PHPA Polymer Concentration Test Instruction Manual
polyacrylamide (PHPA) concentration in mud systems. In this test, the sample is reacted with sodium hydroxide (caustic digestion) at 200 – 250 o C (392 – 482 o F). Ammonia is liberated as hydrolysis of the polymer occurs. The ammonia is
Properties of Polyacrylamides
are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly
Oscillatory and steady shear rheological properties of aqueous polyacrylamide solutions
1/12/2018 · Polyacrylamide (PAA), having a viscosity average molecular weight (M v ¯) of 8 × 10 6, was chosen to prepare the desired test fluids in the concentration range of 0.25% wt./vol–0.6% wt./vol. The concentration levels were chosen to achieve
Synthesis and evaluation of partially hydrolysed polyacrylamide (PHPA) as viscosifier in water based drilling fluids
Concentration dependence of PHPA polymer on plastic viscosity of the mud system is present-ed in Fig. 1. Viscosity increased rapidly with in-creasing polymer concentration, reached a maxi-mum value and then decreased producing a hump, however
