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 to carry c

Concrete additives are chemicals and materials blended into the cement to alter its performance. Additives provide a specific benefit for a particular job. Liquid additives used during cement grinding improve the strength of the cement. Concrete bonding additive bonds old concrete to new for interior and exterior jobs like wall capping and resurfacing. Color additives give concrete a stylish look. Whatever the job, concrete additives help get it done. Cold weather concrete has superior properties to concrete placed in hot weather. At low temperatures, though, concrete sets and gains strength more slowly because the cement doesn't hydrate as fast. Setting time is increased about one-third for each 10 degree decrease in concrete temperature down to 40 degrees Fahrenheit. Accelerating admixtures can help to offset these effects of low temperatures on setting and strength gain. They should meet the requirements of ASTM C 494, Standard Specifications for Chemical Admixtures for Concr

Fracturing is one of the main facilities for increasing oil and gas wells. Fracturing is the use of high-pressure pump fracturing fluid injected into the formation, the formation of cracks and the expansion of new cracks and fill proppant, thereby enhancing the permeability of the formation. After the fracturing process equipment is determined, the effect of fracturing is mainly determined by the fracturing fluid. Early fracturing fluid is the gasoline as a dispersion medium, adding a certain viscosity of the fluid, which is the earliest oil-based fracturing fluid. This was first used in oilfield around 1948’. After that traditional water-based guar gum fracturing fluid was developed to adopt more complicated conditions like deeper well, a wide range of temperatures and higher viscosity request. While there are some disadvantages of Guar gum fracturing fluid, like high content of undissolved substance and residue, incompletely breaking. All these would easily cause formation damag

Crude oil development and production in oil reservoirs can include up to three distinct parts: primary, secondary, and tertiary (or enhanced) recovery. One of the most important use of polyacrylamide is in subsurface applications such as enhanced oil recovery (polymer flooding), where high viscosity aqueous solutions are injected to improve the economics of conventional water flooding.  For oil extraction applications, polyacrylamide is used to increase the viscosity of water to improve the effectiveness of the water flooding process. A polymer solution is more viscous than brine without polymer. In a flooding application, the increased viscosity will alter the mobility ratio between the injected fluid and the reservoir oil. The improved mobility ratio will lead to better vertical and areal sweep efficiencies and thus higher oil recoveries. Polymers hve also been used to alter gross permeability variations in some reservoirs. In other words, the PAM-injected solution assists in swe

Sinofloc has developed a wide range of polymers , both in dry powder and liquid emulsion forms, to cover the vast majority of existing conditions within the various industries (water treatment, mining processing, oil & gas etc.). Sinofloc polyacrylamides range from cationic to non-ionic and anionic in nature, and the selection of the best product depends on several parameters. General guidelines regarding typical product selection for a given application used in a specific industrial can be found on the individual product technical data sheets, as well as in the sections regarding the industries we serve. However these are not to be taken literally. In order to select the optimum product for a specific application, it is essential that laboratory testwork followed by plant trials are carried out. Initial laboratory testwork will give an indication of the best product and approximate dosage, which will then need to be confirmed with more accuracy by running plant trials

Treatment of natural water and sewage is closely linked to preservation of the environment and is thus an actual present day problem. During the last decades there have been noticed substantial increase of the content of heavy metals, mineral oil, poorly-oxidable organic compounds, synthetic surfactants, pesticides and other pollutants from insufficiently treated effluents of industrial and municipal enterprises in open water reservoirs. In spite of the great number of elaborations reported in literature, the problem of natural  water and sewage treatment  has not yet been solved. Hence, the technology of water treatment needs further perfection which mainly includes the ways of intensive use of reagents, in particular flocculants. For these purposes water-soluble high-molecular compounds among which the most widespread and universal are polyacrylamide flocculants are used. As a result of their application the efficiency of removal of heavy metals is increased by 95%, compounds of phos

Polyacrylamide (PAM), general known as flocculants, is the linear polymers with the molecular weight between 5-25 million. Its solid product appearance is white or slightly yellow powder, while its liquid is no colored viscous emulsion. This products is easily soluble in water and decomposed when the temperature is more than 120 ℃.  The positive group (-CONH2) in polyacrylamide molecule could easily adsorb and bridge with the dispersion of suspended particles in the solution which makes it a strong flocculation characters. That’s why polyacrylamide could be widely used in water treatment, paper, mineral processing and other fields. While what we discuss today is not about the application as above fields. Polyacrylamide could also be used be effective friction reducer in Oil & Gas field . Friction reducer, or called drag reducing agents are the agents that could reduce the resistance of a fluid to transport which are mostly water-soluble or oil-soluble polymer. Actually 200 ye

Polyacrylamide emulsion is a new polymer material made of acrylamide through special process polymerization since 1960s. The polyacrylamide emulsion is by a polymerization reaction in which a water-soluble monomer (acrylamide) is dissolved in an aqueous phase and dispersed in a non-polar liquid by means of an emulsifier to form a water-in-oil type emulsion. Inverse Emulsion Polymerization is a way that water-soluble monomer has the same high polymerization rate and high molecular weight as conventional emulsion polymerization. This could enables efficient polymerization of water-soluble monomers into a milky polymer and the reaction temperature is smooth and easy to control which could reduce the cross-linking and branching reaction. The product molecular weight can be free to adjust and is conducive to the application. The drag reduction agent is the most important component in the slick water fracturing fluid system. When the polyacrylamide emulsion is used as the drag reducing age

In the mining industry, effective separating the mineral solids from water or aqueous solutions is critical. If there is no effective flocculation in sedimentation or centrifugation process, the heavier inorganic solids may fall to the bottom of the settler and the smaller particles will be suspended in the supernatant, such as the standing solution. Then the efficiency of filtration and dehydration is also significantly decreased by the existed of small amounts of particles in the supernatant. While these small particles can be quickly settled down by adding Polyacrylamide (PAM) to this aqueous dispersion, in this process the individual particles in the suspension tend to aggregate to form heavy aggregates easily and settle very quickly and the upper dispersion becomes a clear liquid. Coal Washing The active groups on the polyacrylamide molecular chains of coal washing adsorb on the surface of the fine particles in the slime water, which connect the particles and make the fine pa

As we all know, China is a country with scarce water resources. Environmental protection is the key to ensure the sustainable development of the material basis. The protection of water, treatment of water pollution is an important part of environmental protection, so the application of polyacrylamide PAM in water treatment is of particular significance. Polyacrylamide is the world's most widely used, the highest performance of organic polymer flocculants, which is also the most popular used flocculants in China currently. Polyacrylamide is mainly sold in two forms of goods, one is powder, and one is emulsion. The most commonly used is powder products as emulsion is not easy to transport and not convenient to use. There are cationic, anionic and non-ionic several types polyacrylamide, suitable for different purposes and different flocculation objects. Polyamide (PAM) amide (-CONH2) can be affinity with many substances, adsorption to form hydrogen bonds. The high molecular weight PAM

In the metal metallurgy field, whether it is the initial mineral processing or late refining process, a solution as a reaction carrier will be used, and the enrichment of minerals will be deposited to obtain high concentrations of metal compounds through solid-liquid separation. In this series of complex mineral processing, enrichment and separation process, various additives are needed to strengthen and improve the settlement, solid-liquid separation efficiency. For a variety of mining and metallurgical industry, Sinofloc developed a series of polyacrylamide products, which has good application in gold and silver precious metals smelting, alumina industry, iron and steel smelting, zinc/ copper/ lead smelting and other areas of mineral separation problems. Through using different models of polyacrylamide, the solid-liquid separation and effect of enrichment could be greatly improved in the process of beneficiation, tailings flotation, concentration and sedimentation, washing sediment

Hydraulic fracturing is the main measure for increasing oil and gas injection in oil and gas fields. In recent years, due to the foreign monopoly of guar gum, leading to the supply tension in international market which affect the progress of fracturing. Moreover prices of guar gum rose sharply, resulting in a substantial increase in the cost of fracturing. In order to solve the above problems, it is necessary to develop a new type of fracturing fluid to replace the guar gum system fracturing fluid for the geological characteristics of the oil field, so as to reduce the cost of fracturing and ensure the smooth construction of fracturing. Polyacrylamide is often used to carry out oil displacement and profile control and water shutoff. The gelation performance is similar to that of guar gum and the cost is relatively lower. Therefore, it is of great practical value to develop the formulation of polyacrylamide fracturing fluid. Polyacrylamide fracturing fluid has been used widely in oil

Crude oil and oil layers, like groundwater, is ejected upwards along the borehole once the holes are drilled, owing to the oppression of the oil itself by the huge energy of the reservoir (dissolved air, the top of the gas). According to this principle, the exploitation of crude oil in the oil field development is a primary oil recovery and this time the wells are from the well. Along with the continuous recovery of crude oil, the original energy of the reservoir gradually depleted, crude oil cannot be ejected. The recovery rate of a single oil recovery is generally only around 15%. It is called secondary oil recovery when the reservoir water or non-mixed gas to add oil layer energy to promote the oil to move to well, and thus further extraction of crude oil in the oil field could be developed. As the composition of the oil layer of rock particles size is not uniform, irregular shape, resulting in different layers of pore size, permeability heterogeneity. The greater the permeability

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
