Polyacrylamide PAM water treatment application

PAM

Description:

PAM is a linear water-soluble polymer, and is a kind of widely applied in the Water soluble polymer. t consists of acrylamide monomer polymerization, the molecular backbone with large side group.- Amide group. Amide group activity is very big, can reaction with various compound and produce many PAM derivatives. So, polyacrylamide is not only a series of derivatives, but aslo has a variety of valuable properties, such as: flocculation, anchoring (thick), surface activity, etc. Polyacrylamide is a kinds of series of products. Because of the different relative molecular mass and electrical ,so there are many different varieties, and molecular world of the senses in base reaction and derived more varieties, these products have their own unique performance, therefore has the corresponding use object. General which can be divided into several categories.

From the relative molecular mass to classification, can be divided into low molecular weight polyacrylamide (molecular weight below 1 million), the relative molecular mass polyacrylamide (relative molecular mass in 1 million ~ 10 million), high molecular weight polyacrylamide (relative molecular mass 10 million ~ 15 million), ultra high molecular weight polyacrylamide (relative molecular mass in more than 17 million).

Polyacrylamide series products according to the ion characteristic can be divided into the categories: nonionic and anionic, cationic and amphoteric polyacrylamide. The polymers can be homopolymer, also can be copolymer.

PAM molecular chain is very long, this makes it between particles in bridge, pull them together and rapid settlement; Polyacrylamide can greatly reduce the fluid energy. through the pipeline .Therefore polyacrylamide in many fields have a wide range of USES. The use of polyacrylamide in China of the first four large were production industry, water treatment, ore dressing and coal washing, papermaking.

Polyacrylamide PAM water treatment application

Application Field:

1.Polyacrylamide is widely used in oil production of chemical additives (oil additives) drilling mud agent, water shutoff profile control agent, tertiary oil displacement agent, etc.

2.Polyacrylamide is widely used as a mining mineral processing reagents, such as copper, iron ore, gold flotation and tailing water treatment, coal mine coal washing flocculation and water treatment, starch factory and alcohol plant of starch and vinasse recovery, etc.

3.Polyacrylamide is widely used in drinking water, water supply and drainage of various processing, such as tap water factory system water, metallurgy industry sewage treatment, oil chemical industry wastewater treatment, food industry wastewater treatment, pharmaceutical enterprise sewage treatment, and urban sewage of comprehensive treatment, caustic soda production, industrial brine purification, phosphoric acid process flocculation precipitation and so on many kinds of industry, PAM flocculation precipitation effect is very good.

4.For all kinds of sludge dewatering, according to the different sludge properties choose corresponding product brand, can effectively in the sludge into the dehydration machine before gravity sludge dewatering. Dehydration, produce floccules big, do not glue the filter cloth, in filter without diffusing, consumption and dewatering efficiency is high, the mud cake moisture content under 80%.

5.In the paper industry, polyacrylamide is used as paper strengthening agent, textile industry used as sizing agent and fabric finishing agent, the construction industry used for coating of the thickener and the cement of anchoring and chemical grouting agent, but also can be used for desert governance, afforest not of super absorbent polymers, such as soil amendment.

Application Method:

1. The product should be prepared for the water solution of 0.1% as concentration. It is better to use neutral and desalted water.

2. The product should be scattered evenly in the stirring water, and the dissolving can be accelerated by warming the water (below 60 °C).

3. The most economical dosage can be determined based on a preliminary test. The pH value of the water to be treated should be adjusted before the treatment.

Package and Storage:

1. The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.

2. This product is hygroscopic, so it is should be sealed and stored in a dry and cool place below 35°C.

3. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.

Q:What is chemical adsorption and its relationship with heterogeneous catalysis: The catalytic cycle includes five steps: diffusion, chemical adsorption, surface reaction, desorption and reverse diffusion.The chemical adsorption is an important part of the heterogeneous catalysis process, and the adsorption of the reactants on the catalyst surface,

Q:Is it possible for the different chemical reactions to have the same catalyst?: Right, think about the catalysis of biological enzymes

Q:Pls help me define a catalyst.?: A substance which speeds up or slows down a reaction without taking part in it.

Q:Are the catalysts for upgrading the weapons components that i may have a few of, or very rare ones?: Catalysts can only be used when the item is ready to evolve. On top of that you can't use a different kind of catalyst than the one actually require and you can't use too many or too few. Catalysts are basically automatic as long as you have enough, all you can do is choose to use them. On the other hand, you CAN accidentally use sells for a premium as a material. Those items are universally horrible as a material, but sell really well in the shop. Don't use them by accident, sell them as soon as you can.

Q:What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change: The principle of the catalyst: the catalyst is mainly by reducing the activation energy, so that the reaction is easy to carry out, so as to achieve the catalytic effect.

Q:What is the chemical vinyl chloride and benzene plus catalyst?: Looks like no ethyl benzene, it is vinyl benzene

Q:Which branch of chemistry or what specialty can study the catalyst: Organic Chemistry: Application of Inorganic Catalysts in Organic Reactions, Preparation and Application of Organic Catalysts (such as Macromolecular Resins, Phase Transfer Catalysts), Preparation and Application of Catalysts for Organic Compounds

Q:The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?: The change in chemical reaction rate is the same as the chemical nature and quality

Q:The properties of scandium: Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...

Q:Please make it simple because I need it for school and please give to examples for the second part Thanx :D: A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
