Sinofloc   polyacrylamide flocculants  has good performance in thickening, flocculation, and fluid rheology modifiers, which is widely used in drilling, plugging, water acidification, fracturing, wash well, completion, drag reduction, scale and drive oil . Currently many oil fields have entered the field of secondary, tertiary recovery, reservoir depth of 1000m above generally in some reservoir depth of 7000m, heterogeneity and offshore oilfield in oil production operations to the proposed more stringent conditions, deep oil and offshore oil corresponding to PAM also raised new demands to shear resistance, high temperature (above 100 ℃ up to 200 ℃), resistance to calcium ion, magnesium ion, seawater degradation. Our products show a good performance in Enhanced oil recovery (EOR). Partially hydrolyzed polyacrylamide (HPAM) is often used as drilling adjusting agent, which consists of polyacrylamide hydrolysis. Its role is to regulate the rheology of the drilling fluid t...

The settlement and separation of red mud is an extremely complex physical and chemical process. Bayer method dissolution of pulp from the red mud is red mud and the formation of sodium aluminates solution suspension. Since there are complex physical and chemical effects exist between the red mud particles and between the red mud particle and the solution, the phase composition or red mud, grain fineness distribution, surface morphology of red mud particle and solid content of red mud liquid, liquid ingredients, red mud fluid temperature and so on have significant defects on the processing of settlement and separation of red mud. If the flocculating agent is properly selected, the application of flocculants technology can make solid-liquid separation speed improved greatly, and reduce the size of the equipment. The mechanism of the polymer flocculants is that the effective flocculation between particles through absorption and bridge, surface absorption and charge neutralization can form...

Polyacrylamide emulsion is prepared by dispersion or inverse emulsion polymerization, which is a form of polyacrylamide liquid present. Besides the characteristics of solid polyacrylamide flocculants, through the molecular chain of polar groups to adsorb suspended solids in the water particles, the emulsion could formats the large flocs through bridge between the particles or electricity. Polyacrylamide emulsion is divided into two types, water-in-oil, and water-in-water. Unlike polyacrylamide powder, the drying process is not required in the emulsion type polyacrylamide manufacturing process. Therefore, the polyacrylamide emulsions molecular weight and water solubility than the same powder polyacrylamide molecular weight is higher. Water-in-oil emulsions are usually water-insoluble. Therefore, in the emulsion-type polyacrylamide manufacturing process, or in the use of emulsion before the dissolution of the dilution process, the need to add a hydrophilic surfactant, so that when the ...
