Although flocculants such as aluminum and iron salts have a good decolorizing flocculant effect for disperse dyes, sulfur dyes, and vat dyes, for water-soluble dyes, the decolorization effect is not ideal. As a new type of cationic polymeric flocculant, PolyDADMAC has a 100% cationic degree and special chemical structure, which makes it in good flocculation and decolorization effect. Therefore, PolyDADMAC has become a popular flocculating and decolorizing product for dye wastewater, but its decolorization effect is also affected by the following factors.

1. The effect of molecular weight on the decolorization of PolyDADMAC dye wastewater

When the dosage of PolyDADMAC is insufficient, it can not completely neutralize the negative charges of dye molecules, which will lead to the failure of some dye molecules to form neutral molecules and precipitate from the solution; when the dosage of PolyDADMAC is too large, the neutral dye molecules which have been precipitated may be positively charged due to the excessive positive charges, which will lead to the mutual repulsion of dye molecules and the formation of stable colloidal solution. Therefore, only when the dosage of PolyDADMAC is appropriate, can all dye molecules form neutral molecules, precipitate from the solution, and be removed by flocculation. In addition, the higher the intrinsic viscosity of PolyDADMAC is, the less the optimal dosage is, and the better the decolorization effect is.

2. The effect of pH value on decolorization of dye wastewater

Different pH values of the solution have different effects on the structure of flocculants and the molecular structure of dyes. Therefore, the ability of flocculants to combine dyes and the aggregation performance and size of precipitates generated by the reaction are different, which leads to different sedimentation removal capacity. So there is an optimal pH range for general flocculants, while PolyDADMAC has a wide range of pH values for the treatment of reactive dyes and disperse dyes.

We can also provide kinds of superabsorbent polymer for sale, if you are interested, please contact us.

Superabsorbent polymer (SAP) could be used as water retaining agent, which is a kind of functional high polymer materials with special ability to absorb water. In agriculture field, it is compared to “micro-reservoir” by people because it features non-toxic and harmless, repeated water release and water absorption. At the same time, it can also absorb fertilizer and pesticide, then release them slowly to increase the fertilizer and pesticide effects. Super absorbent resin is widely used in agriculture, forestry, horticulture and building materials.

The whole world has been watching the event – drought. Since the 1950s, with the rapid industry development and the rapid population expansion, the problem of climate warming and drought is becoming more and more prominent. So, scientists from all over the world must begin to study effective ways to solve the problem – drought. In the 1980s, the absorbent composite was produced. Then it develops rapidly because it can improve the salinity tolerance of super absorbent resin, the water absorption speed and the strength of hydrogel after water absorption, etc. In recent years, scientists have begun to study the blending technology of absorbent polyblend, which provide a broader prospect for developing super absorbent materials.

The water absorption principle of water retention agent is the same as the general SAP. It is formed by the expansion of tension (which is produced in water the polymer electrolyte molecule chain amide base and/or carboxyl group) and the expansion of tension (which is produced because of the restriction molecular chain of intersection point) interacting each other. Polyacrylamide, for example, there are a large number of amide and carboxyl hydrophilic group in the water retaining agent. By osmotic pressure (which is produced by concentration difference between resin internal ion, base group and the aqueous solution related components) and the affinity (which is produced by polymer electrolytes and water), a lot of water can be absorbed until the concentration difference disappeared. However, rubber spring can control water retaining agent to achieve satisfactory water absorption level. The higher crosslinking degree of the molecular structure is , the stronger the rubber elastic force is. And the equilibrium point of the rubber elastic force and the suction force is its apparent absorption capacity. Water retaining agent does not dissolve in water, but it can absorb water which is quite into one hundred times its weight. Water retaining agent can effectively inhibit the water evaporation. After the water retaining agent is infiltrated in soil, to a great extent, the water evaporation is suppressed, the saturated water content of soil is increased, and the saturated water conductivity of soil is reduced. So, it can slow down the speed of soil releasing water, reduce the loss of the soil water infiltration and achieve the goal of catching water. It can also stimulate crop root growth and development, increase the root length and the root number. Finally make crop keeping good growth under drought condition.

SINOFLOC superabsorbent polymers (known as SAP) are water insoluble polymer, cross-linked copolymer of acrylic acid. It can absorb water which is hundreds to thousands of times heavier than its own, and it has excellent water retention. Once the absorbed water is expanded into a hydrogel, it is difficult to separate the water even when it is pressed. Therefore, it is widely used in personal hygiene products, industrial and agricultural production, civil construction and other fields.

Because of the strong water absorption capacity and excellent water retention property, the water holding polymers absorbent is widely used in agriculture and forestry fields as the soil water retention agent. China is lack of water resources. Therefore, the application of water retaining agent becomes more and more important. Currently in domestic, water retention polymer products have been used for many kinds of plants in the fields such as grain, cotton, oil, sugar, tobacco, fruit, vegetables, forest etc. And in the northwest, Inner Mongolia and other areas, we use the high absorbent resin to control sand and afforest in large area. The high absorbent resin used in this area is mainly starch grafted acrylic acid salt polymerized crosslinking and acrylamide – acrylic acid salt copolymer, in which salt has been transferred from sodium to potassium type. The method is mainly used to mix seed, spray, acupoint, or soak plant roots with water and high absorbent resin. At the same time, the fertilizer can be coated with high absorbent resin, and the utilization ratio of fertilizer can be fully utilized to prevent waste and pollution.

Since the superabsorbent water insoluble polymers features non-toxic, non-irritating to human body, non-side effects and without causing blood coagulation, it has been widely used in the field of medicine and daily use in recent years. It is mainly used as sanitary napkin, baby diapers, napkin, medical ice bag, etc. Superabsorbent (SAP) is a kind of typical functional polymer materials. It can absorb water which is hundreds of times or even a thousand times as its own weight, and has a strong capacity of water retaining, so it is also called super absorbent or water absorbent resin SAP. The effect on diapers is becoming more and more important, becoming an important part of the diaper absorption chip. Sinofloc SAP can absorb and spread quickly when the liquid penetrates to ensure that the diaper keep dry.

We can also provide kinds of anionic polymer for sale, if you are interested, please contact us.

Amphoview polyelectrolyte has the characteristics of cationic and anionic. It can complete the synergistic action of anions and cations without any precipitates, especially for the sewage with complex water quality situation or water property changing frequently. Usually when in the process of sewage, it will generate more significant synergies when anionic and cationic used together than when alone, and the ability of zwitterionic polyacrylamide to reduce the surface tension is far greater than under the same conditions the performance of cation or anion exist alone. To meet the requirement of reducing the surface tension, it is necessary to use both anionic and cationic polyacrylamide powder, but if they are used in a wrong way, both can produce white sediment, thus losing the use effect.

In the paper industry, as a papermaking agent, the effect is even more than that of a single characteristic polyacrylamide. Especially in the retention and filtration, it can improve the water filtration speed under the net and reduce the loss of fiber. It also has a positive effect on the wet end system and the paper smoothness, strength as well as minimizing the difference of both sides.

When used in the papermaking industry, the retention rate of fillers, pigments and so on can be improved. It can reduce the loss of raw materials and environmental pollution, also improve the strength of paper (including dry strength and wet strength), in addition, the use of amphoteric polyacrylamide (PAM) can also improve paper tear resistance and porosity, to improve vision and printing performance, also zwitterionic polyacrylamide for molecules containing cationic and anionic, shows more excellent performance. This kind of flocculating agent can be used in a wide range of PH value, has a higher water filter, the bottom of the filter cake moisture content, also can be used in the acid leaching of ores or from acidic catalyst containing metal recycling valuable metals.

Amphoteric polyelectrolyte, used in the feed of protein recovery, is stable in quality and good in performance. The chicken protein powder recycled has no side effect on the survival rate, weight gain and egg production. It also can be applied in synthetic resin coating, civil water plugging grouting materials, building materials industry, improving the quality of cement, construction adhesives, caulking repair and plugging agent, soil improvement, electroplating industry, printing and dyeing, etc. It is several or dozens of times more effective than Inorganic salts because such wastewater is generally negatively charged. The molecular weight of water-soluble azo initiator AIBA has been increased to more than ten million.

For high brines conditions in fracturing, SINOFLOC team synthesized the anti-temperature and salt-resistant fracturing fluid thickener with acrylamide monomer and amps chemical and by using free copolymerization of an aqueous solution. The optimum conditions of synthesis were determined by lab experiments. The results show that the fracturing fluid has excellent resistance to temperature and salt resistance, and has the characteristics of shear resistance, which is completely broken and the less residue of the filtrate and also less damage to the formation.

At present, many oil fields have entered the enhanced oil recovery stage of high water cut stage. Lab experiments and field test studies have shown that polymer flooding is an effective way to improve oil recovery, and has broad application prospects. However, although the most commonly used polyacrylamide has a certain oil displacement effect, the viscosity of polyacrylamide decreases rapidly with the increase of the mineralization degree of formation water. At the same time, the oil well temperature of the oil layer is higher and the thermal stability of polyacrylamide is affected. In addition, in the polymer solution injection process, the bottom of the hole when the perforation of the polyacrylamide will cause strong shear, will lead to polyacrylamide molecular chain fracture, the apparent viscosity greatly reduced. Therefore, polyacrylamide in the high salinity, high temperature, and high shear, the oil displacement effect is not ideal. SINOFLOC R & D team was modified with acrylamide and 2-acrylamide-2-methyl propane sulfonic acid (AMPS) as the raw materials, and free radicals hydrophobic associative polymer was synthesized by micellar polymerization. The molar ratio of AM and AMPS, the content of hydrophobic monomer to the intrinsic viscosity of the polymer and the apparent viscosity of polymer solution were studied systematically. The effects of the molar ratio of initiator and reducing agent, the molar ratio of AM to AMPS come to the appropriate reaction conditions. AMPS and the introduction of hydrophobic groups can improve its temperature resistance and hydrolysis resistance. The amp polymer can improve the water flooding ideally when polymer flooding, and also promote the application of the polymer system in different salinity and temperature reservoirs.

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 polyacrylamide friction reducer in Oil & Gas field.

viscosity modifying friction reducers, 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 years ago, people already found that the viscosity of the skin of the marine animal has drag reduction effect, and even more the turbid water flows faster than the clean water. And also there was evidence that there would be smaller surface friction when the ship was in the water with algae. Based on above observation and study, in last century, scientists found that certain natural resins, linear polymers, organic soaps, etc. could reduce turbulence friction in different levels. The term of ‘friction reducer’ or drag reduction is first time cited the since then. Along with the technology development, scientists found that polymer dilute solution or elastic material surface can achieve reduction and the boundary shear turbulence generated by the basic laws is closely linked. The viscous drag reduction is either by changing the boundary conditions of the fluid from the outside or by changing the boundary conditions from the inside. By changing the physical, chemical, mechanical properties of the boundary material or by injecting the gas, liquid and liquid with different physical, chemical and mechanical properties in the near, could change the flow and kinetic characteristics of the near-wall region, so as to achieve the purpose of drag reduction technology.

When polyacrylamide used as friction reducer chemistry to add into the fracturing fluids, this product could reduce the pipe friction and through using Sinofloc polyacrylamide as friction reducer, the liquid in the turbulent flow resistance is greatly reduced.

In last century, the cleaning water together with mudstone cuttings in the drilling process was used as natural stable drilling fluids. Later the drilling fluid chemical agent was developed as a more stable quality drilling fluids to ensure the safety of drilling. The Polyacrylamide (PAM) was begun to be used in drilling fluid chemical in 1960’, while this approach has led to a significant change of the development of low solids non dispersed fluids. Polyacrylamide not only increased drilling speed greatly, but also promoted the type of drilling fluid treatment agent from the past to the synthesis from natural polymers.

The main functions of drill mud polyacrylamide are: cleaning the bottom, carrying cuttings; cooling and lubrication drill and drill string; the formation of mud cake to protect the wall; control and balance formation pressure; cuttings and aggravating agents; in the ground to remove debris; to provide information about the drilling formation and so on. Nowadays, polyacrylamide (PAM) has played an important role in drilling fluid loss, flocculation, shale inhibition, dilution, plugging and so on. The solid phase in the drilling fluid is one of the key factors affecting drilling speed and cost. Along with the introduction of drilling fluid agent polyacrylamide phpa into drilling fluid and the application of high-quality drilling fluids without dispersing low-solid-phase polymers have greatly increased the drilling speed and become one of the four important technologies in the contemporary drilling industry.

Through working with field engineers and many testing in oilfield, Sinofloc engineers found our polyacrylamide (PAM) can make the cuttings and inferior soils in the drilling fluid be in non-dispersed flocculation state, so as to use mechanical solid control equipment to remove them, so as to solve the dispersion of drill cuttings in the dispersed drilling fluid system well, Liquid accumulation problem. Sinofloc products could not only improve the penetration rate, but also reduce the drilling process of many complex situations, better protection of the oil and gas layers and reducing the cost of drilling.

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 and highest performance organic cleanwater anionic polyacrylamide flocculant, which is also the most popularly used polyacrylamide flocculant water treatment 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 forms a “bridging” between the adsorbed particles, allowing several or even dozens of particles to be joined together to produce flocs to accelerate the subsidence of the particles, making it the ideal flocculants. PAM flocculants is mainly used to deal with various wastewaters, and compared with the traditional inorganic flocculants advantages are: easy to adapt to a variety of conditions, small dosage, high efficiency, less sludge generated, post-processing easy.

Municipal sewage treatment plants and industrial wastewater treatment plants usually use polyacrylamide PAM and other flocculants flocculation clarification and purification treatment. Generally in a secondary sewage treatment plant, the amount of sludge generated by the sewage treatment is about 0.5% -1.0 % of the sludge produced by the need to dehydrate to produce clean water and high solid content of the filter cake, and reduce the weight and volume of waste sludge to improve the effectiveness of incineration and fertilizer production. Many sewage treatment plants use filter press to improve the dehydration rate, this sludge is very hydrophilic, with a negative charge, which is difficult to dehydrate. In the mechanical dehydration before the use of acrylamide polymer must be effective pretreatment to improve the sludge performance; improve the production capacity of mechanical equipment, sludge dewatering polyacrylamide PAM more and more inclined to use Cationic Flocculants products, especially acrylamide And copolymers of propylene-hydroxyethane trimethylamine We can also provide kinds of oilfield chemicals for sale, if you are interested, please contact us.
