PAM polyacrylamide development trend and its application in water treatment
Environmental protection is the material foundation, and protection of water resources, water pollution control and governance is an important part of environmental protection. With the development of environmental protection, sewage and sludge produced in the process of water treatment disposal, people pay more and more attention. The polyacrylamide (PAM) has a very important role in the field of water treatment. In our country is very poor water resources area, average annual water resources total 2.8 trillion cubic meters, ranking sixth in the world, but the amount per capita only 271 cubic meters, equivalent to the world average amount per capita quarter, ranking No. 88 in the world. In China, the PAM application in water treatment is very important. PAM is a linear water soluble polymer, a water soluble polymer in one of the most widely used varieties. PAM and its derivatives can be used as effective flocculants, thickening agent, drag reduction agent, widely used in water processing, paper making, petroleum, coal, geology, construction and other industrial sectors. Due to the high molecular weight of PAM (103 ~ 107), water soluble, regulation of molecular weight and introduce a variety of ionic groups in order to obtain specific performance. Its molecular weight is an important flocculant, it is widely used in sewage treatment and drinking water.
Polyacrylamide is a water soluble polymer, which has good flocculation ability. It can reduce the friction resistance between the liquid and the ionic characteristics can be divided into four types: non ion, anion, cation and type. Media said polyacrylamide as a synthetic water-soluble polymer compound, is a more ideal paper chemicals and water treatment chemicals, the world's largest use, the most widely used. Among them, China is the world's largest polyacrylamide consumption region.
According to the investment adviser released the 2010-2015 China polypropylene market investment analysis and forecast report shows that in 2008, global consumption of about 840000 tons, China's consumption of about 330000 tons, accounting for 38% of total consumption, the United States, Western Europe, Japan's consumption than cases were 22%, 15%, 13%.
Although China is the world's largest polyacrylamide consumption area, but in our country, the application of polyacrylamide and other countries in the world have great differences. At present, the world's other countries are mainly used in water treatment and paper industry, while the application of Polyacrylamide in China mainly concentrated in the oil extraction industry. According to China's polypropylene market investment analysis and forecast report released by the investment adviser, 2010-2015, China, in China, polyacrylamide as the three oil displacement agent, applied to the oil industry, the proportion of the total consumption of about 60%.
Due to the large proportion of polyacrylamide used in oil exploitation industry in China, the demand of oil increases with the increase of the domestic economy, which will stimulate the growth of the demand for oil. Moreover, due to the rapid economic growth, industrialization and urbanization brought about by the high pollution problem is gradually highlighted, will promote the development of water treatment and other environmental protection industry, thus increasing the demand for polyacrylamide. Coupled with the development of domestic paper, textile, coal, mining, metallurgy and other related industries are relatively stable, but also conducive to the development of polyacrylamide application space, the future market capacity of China's polyacrylamide will gradually increase.
