PHPA (Partially Hydrolyzed Polyacrylamide) - Manufacturer
PHPA/Polyacrylamide Easily soluble in water, PHPA/Polyacrylamide (Partially Hydrolyzed Polyacrylamide) is a type of co-polymer, which is acknowledged for its thickness increasing properties, optimal viscosity and high flocculability. This polymer is widely used in oil extraction process for its good oil recovery property.
Polyacrylamide in the form of aquagel is partially hydrolyzed in such a manner that small pieces of the aquagel are mixed with an alkali agent in a specified quantity and maintained at a temperature of 50° to 95° C. until the hydrolysis reaches substantial completion.
Effect of partially hydrolyzed polyacrylamide
The effect of HPAM on emulsion stability of the stimulated PWPF was investigated in this study. HPAM increases viscosity, interfacial tension, absolute zeta potential value, and interfacial dilational viscoelasticity elasticity of oil droplets, making oil droplets difficult to approach and coalesce.
We offers 598 partially hydrolyzed polyacrylamide powder products. About 78% of these are petroleum additives, 70% are paper chemicals, and 47% are plastic auxiliary agents. A wide variety of partially hydrolyzed polyacrylamide powder options are available to you, such as water treatment chemicals, coating auxiliary agents, and petroleum additives.
Synthesis and evaluation of partially hydrolysed
solution was used. The hydrolyzed product (PHPA) was then recovered by precipitating in methanol and dried in vacuum oven for 5 h at 60°C. Molecular weight of polyacrylamide was determined by viscometric method!" where:1]: = 6.8 x 10-4 MnO.66• The intrinsic viscosity:1]: was determined at high shear rates after attaining the Newtonian behaviour.
PHPA (Partially Hydrolyzed Polyacrylamide) Powder should be added in fresh water to get a highly viscous drilling fluid in Delhi. The marsh funnel viscosity for clay or shale formation should be ≥ 50 seconds per quart and ≥ 60 seconds per quart for sandstone or unconsolidated sand.
PHPA Partially Hydrolyzed Polyacrylamide Suppliers
PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment. In drilling fluids, PHPA is an anionic polyacrylamide and it can act as a viscosifier, flocculants, friction reducer and fluid-loss control agent.

Rheological Properties of Partially Hydrolyzed
This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times.
The addition of salt ions to solutions of partially hydrolyzed polyacrylamides yields onset behavior previously observed for nonionic polymers. The differences measured between various solvent properties can be explained by the actual hydrodynamic molecule dimensions for a given molecular weight and polymer concentration.
Molecular dynamics simulations of the conformation
1. Introduction. Partially hydrolyzed polyacrylamide (HPAM) is the most widely used water-soluble non-toxic polymer in water treatment (Zheng et al., 2013), paper mills (Wong et al., 2006), ore processing and crude oil production processes (Pei et al., 2016).It is also used in irrigation water for soil-conditioning (Lee et al., 2011), pesticide formulation (Nair and Sawant, 2006), cosmetic
The most desirable polymer gel systems to diminish the water to oil ratio in petroleum fields for enhanced oil recovery (EOR) are based on partially hydrolyzed polyacrylamide because of these
- How effective is PAMC flocculation in turbid water clarification?
- Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.
- What is a polymer flocculant?
- Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
- Is polyacrylamide grafted hydroxypropyl methyl cellulose a biodegradable flocculant?
- Das R., Ghorai S., Pal S. Flocculation characteristics of polyacrylamide grafted hydroxypropyl methyl cellulose: An efficient biodegradable flocculant. Chem. Eng. J. 2013;229:144–152. doi: 10.1016/j.cej.2013.05.104. [ CrossRef] [ Google Scholar] 97.
- Does cnpam flocculant have a good universality for high turbid water?
- The fractal dimension analysis indicated floc size increased with the enhancement of the CNC content in the CNPAM flocculant. It was testified that the flocculant had good universality for high turbid water in different concentrations and with the presence of various inorganic salts.
