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 are the properties of the catalyst (eg, specificity)?: The definition of a chemical reaction in the chemical reaction can change the chemical reaction rate of other substances, and its quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. Catalyst in the role of chemical reaction There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction are more reactive than the original reaction The reaction conditions of the catalyst have been changed by the reaction of the catalyst by the reaction of the catalyst, that is, the quality and chemical properties mentioned above did not change before and after the reaction.

Q:What kind of chemical reaction requires a catalyst?: For example, the system of ammonia, S02 oxidation into SO3

Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent: Activated molecular map

Q:What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?: The catalyst can change the activation energy of the chemical reaction, thereby changing the reaction rate.

Q:What are the characteristics of the catalyst in the chemical reaction?: In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.

Q:the process of which the heterogeneous catalyst work in vehicles. a step by step instruction in how they work. :): The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2

Q:Why the catalyst is required to have a large surface area and a rich pore structure: Because of the chemical reaction, the larger the contact area, the faster the reaction rate, therefore, the catalyst has a large surface area or pore structure, are to increase the contact area of the catalyst and reactants.

Q:High school chemistry, catalyst activation energy map: Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!

Q:how do catalysts help in green chemistry?: Catalysts allow more efficient conversion of products in irreversible reactions, or they allow for the faster attainment of equilibrium in equilibrium reactions, thereby reducing time, raw material waste and emissions. Also, because catalysts are reusable, they can be recycled.

Q:What are the catalysts that appear in the chemistry experiment?: Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
