 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.

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:CO and NO in what the role of the catalyst under the chemical reaction
Palladium Pd, platinum Pt as a catalyst
Q:A biological catalyst or a chemical reaction facilitator is know as a/an?
A biological catalyst is an enzyme. Here are more details for you. Enzymes – biological catalysts Normally chemical reactions do not proceed spontaneously, but require the help of a catalyst. A catalyst accelerates a chemical reaction without itself being changed. For example, the reaction of hydrogen with oxygen to produce water requires the addition of the metal platinum. These days we encounter the concept of a catalyst most often in connection with technology for cleaning up the exhaust fumes from our automobiles, where platinum and rhodium catalyze the breakdown of polluting nitrogen oxides. Chemical reactions within living cells must also be catalyzed. Biological catalysts are called enzymes. There is, for instance, an enzyme in our saliva which converts starch to a simple sugar, which is used by the cell to produce energy, and another enzyme which degrades the excess lactic acid produced when we overexert ourselves. All green plants contain enzymes which convert carbon dioxide in the air to nutritious carbohydrates such as sugar and starch. Without enzymes life would not be possible! Enzymes are highly selective. Among the thousands of different compounds in a cell, an enzyme can recognize the right molecule (substrate) and transform it into a new product. This property arises from the special three-dimensional structure of each enzyme. One can compare an enzyme and its substrate with a lock and its key. Enzymes are very effective catalysts. A chemical reaction might require several months to reach completion without a catalyst, but only a few seconds with the help of an enzyme. Since the enzyme remains unchanged, one enzyme molecule can catalyze the transformation of millions of substrate molecules. Up until the beginning of the 1980's, all enzymes were thought to be proteins. We now know that proteins do not have a monopoly on biocatalysis. RNA molecules can also function as enzymes.
Q:Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction
CO2 + H2 = CO + H2O (conditions: catalyst, generally already heating, and reversible)
Q:Will the catalyst be able to increase the rate of chemical reactions?
In general, the catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
Q:What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
Q:The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
There is no relationship between the catalyst can only change the reaction rate
Q:High school stage chemical catalyst
Manganese dioxide and iron are more common, vanadium oxide sometimes encountered, sulfuric acid is also a catalyst, but generally used as a dehydrating agent. Inorganic catalysts catalyze the object is diverse, unlike the organic catalyst as a single, so hard to say. In high school is probably used to prepare oxygen when the use of manganese dioxide
Q:Characteristics and types of catalysts?
Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
Q:Explanation of Catalysts?
A catalyst is a compound in chemistry (it can be an acid or temperature or a base or a metal or anything, pressure anything) that shifts the reaction towards one product or the other... In simple words. If you want to obtain something, e.g. water, then you can obtain it in different timings, ie in 2000 years, but if you want to obtain it in 2 hours instead of 2000 years then you add a catalyst, e.g. you heat the reaction to speed it up, you add an acid, or a base etc. Some catalysts also act on the regioselectivity of a compound thru preferring the formation of a stereo-isomer to another. E.g. if you want to obtain S-Thalidomide instead of R-Thalidomide you use a particular catalyst etc...
Q:What are the catalysts?
The relationship between it and the reaction system is as highly selective (or specific) as the relationship with the key. A catalyst does not catalyze all chemical reactions, such as manganese dioxide in the decomposition of potassium chlorate Play a catalytic role to speed up the chemical reaction rate, but the other chemical reactions do not necessarily have a catalytic effect
