The oil is China's important energy and chemical raw materials, has a pivotal position in the national economy. The polymer volume used for flooding the oil in China ranks first in the world, and China has become the world's largest polymer flooding country. At present, the international crude oil price continues to rise, and meanwhile the countries take measures to stimulate crude oil exploitation. EOR will be the core flooding technology to Polyacrylamide oilfield-led development and enters a period of rapid development.
Ⅱ, III reservoir resources formation temperature is in the 70-95 °C, while formation salinity is in the 10000-30000 mg /l with 800 mg / l of divalent ions .With the use of regular polyacrylamide under these conditions, there will be serious thermal degradation, the degree of hydrolysis increasing, the case of multi-charged ions combined with precipitation and other issues, the effect of variation of the tackifier. Our polyacrylamide for Temperature and salt resistance in this class reservoir conditions can meet the requirements of viscosity, temperature, salinity and shear performance of flooding.
Polyacrylamide is widely used in oil exploration, profile control, plugging agent, drilling fluids, fracturing fluids additives. For Drop in drilling fluid loss, flocculation, shale inhibition, dilution, plugging, cooling and lubricating the drill bit and drill string, carrying debris, cementing well it also plays an important role in these applications.
The amide group of the Polyacrylamide with many substances affinity adsorption, formation of hydrogen bonds forms bridging between the adsorbed ions in generating floc and acceleration fallout. As compared with the conventional inorganic flocculant: it is with high performance and it can adapt to a variety of conditions, but the dose is small, efficiency is high, less generated sludge is made, post-processing is easy.
●Municipal Wastewater
In the first stage of processing urban sewage, usually the first addition of inorganic coagulant aids in the procedure of the pretreatment of sewage, then Anionic Polyacrylamide is added to enhance flocculation efficiency, to reduce small particles in water bodies.In the activated sludge treatment and the digestion and sludge treatment, in usual, the better choice of medium or high charge of Cationic Product displays the better performance accordingly

●Industrial Wastewater
Due to the different production processes used by different companies in the various industries, the more industrial sewage industry can cause the different nature of industrial sewage. Under the normal circumstances, with the high organic-containing or acid sewage in the water, the optional specially focuses on Cationic, Non-ionic polyacrylamide, if containing large amounts of suspended solids or alkaline effluent ,it is required to select Anionic, Nonionic polyacrylamide .

●Raw Water Treatment
Raw water contains the large amounts of suspended solids.Therefore,it is usually pretreated by using an inorganic flocculant, and then add polyacrylamide for flocculating with the rare monomer residual

Polyacrylamide is mainly applied for seven aspects in paper industry :
1. Enhance the retention of added substance and dyestuff to decrease the loss of raw material and the pollution to environment .
2. Improve the dry-strength and wet-strength of paper.
3. As dispersant of macrofiber paper making.
4. Raise up the Stability of Pulp .
5. As adhesive of Paper Coated Dyestuff.
6. As decorative adhesive of Paper.
7. Used for wastewater treatment from the paper industry.
Polyacrylamide as a water-soluble polymer, has a good flocculation, is widely used in various industries

.●Coal washing
It is able to promote the rapid settlement of slime, the clarification of slurry and water recycling.

●Incense Making
Polyacrylamide with a strong adhesive force, can enhance the bending force and scalability of incense.

●Textile
Polyacrylamide as textile auxiliary can be used as a textile coating slurry sizing can reduce the loom short head and shedding, which helps to enhance the antistatic properties of textiles.

●Ore-dressing
In addition to the mentioned Coal Washing Industry, Polyacrylamide is also widely used in the mining of Gold, Silver, Copper, Iron, Zinc, Manganese, Nickel and other minerals, as well as the settlement industry of Bauxite Alumina red mud.

●Sugar Making
Polyacrylamide in the sugar industry is applied to accelerate the sedimentation of Cane sugar juice and sugar to clarify. Currently, Polyacrylamide used in the most of the sugar mills is generated after the copolymerization polymer of Acrylamide and Acrylic acid. The modern sugar production industry to flocculant selection has an important parameter, which is the content of its residual monomer.
