polyacrylamide:
Description:
PAM is alinear water-soluble polymer, and is a kind of widely applied inthe Water soluble polymer. t consists of acrylamide monomerpolymerization, the molecular backbone with large sidegroup.- Amidegroup. Amide groupactivity is very big, can reaction with various compound andproduce many PAM derivatives. So, polyacrylamide is not only aseries of derivatives, but aslo has a variety of valuableproperties, such as: flocculation, anchoring (thick), surfaceactivity, etc. Polyacrylamide is a kinds of series of products.Because of the different relative molecular mass and electrical ,sothere are many different varieties, and molecular world of thesenses in base reaction and derived more varieties, these productshave their own unique performance, therefore has the correspondinguse object. General which can be divided into severalcategories.
From the relative molecular massto classification, can be divided into low molecular weightpolyacrylamide (molecular weight below 1 million), the relativemolecular mass polyacrylamide (relative molecular mass in 1 million~ 10 million), high molecular weight polyacrylamide (relativemolecular mass 10 million ~ 15 million), ultra high molecularweight polyacrylamide (relative molecular mass in more than 17million).
Polyacrylamide series productsaccording to the ion characteristic can be divided into thecategories: nonionic and anionic, cationic and amphotericpolyacrylamide. The polymers can be homopolymer, also can becopolymer.
PAM molecular chain is very long,this makes it between particles in bridge, pull them together andrapid settlement; Polyacrylamide can greatly reduce the fluidenergy. through the pipeline .Therefore polyacrylamide in manyfields have a wide range of USES. The use of polyacrylamideinChinaof the first four large were production industry, watertreatment, ore dressing and coal washing, papermaking.

Application Field:
1.Polyacrylamide is widely used inoil production of chemical additives (oil additives) drilling mudagent, water shutoff profile control agent, tertiary oildisplacement agent, etc.
2.Polyacrylamide is widely used asa mining mineral processing reagents, such as copper, iron ore,gold flotation and tailing water treatment, coal mine coal washingflocculation and water treatment, starch factory and alcohol plantof starch and vinasse recovery, etc.
3.Polyacrylamide is widely used indrinking water, water supply and drainage of various processing,such as tap water factory system water, metallurgy industry sewagetreatment, oil chemical industry wastewater treatment, foodindustry wastewater treatment, pharmaceutical enterprise sewagetreatment, and urban sewage of comprehensive treatment, causticsoda production, industrial brine purification, phosphoric acidprocess flocculation precipitation and so on many kinds ofindustry, PAM flocculation precipitation effect is verygood.
4.For all kinds of sludgedewatering, according to the different sludge properties choosecorresponding product brand, can effectively in the sludge into thedehydration machine before gravity sludge dewatering. Dehydration,produce floccules big, do not glue the filter cloth, in filterwithout 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, textileindustry used as sizing agent and fabric finishing agent, theconstruction industry used for coating of the thickener and thecement of anchoring and chemical grouting agent, but also can beused for desert governance, afforest not of super absorbentpolymers, such as soil amendment.
Application Method:
1. The product should be prepared forthe water solution of 0.1% as concentration. It is better to useneutral and desalted water.
2. The product should be scatteredevenly in the stirring water, and the dissolving can be acceleratedby warming the water (below 60 °C).
3. The most economical dosage can bedetermined based on a preliminary test. The pH value of the waterto be treated should be adjusted before the treatment.
Package andStorage:
1. The solid product can be packed ininner plastic bags, and further in polypropylene woven bags witheach bag containing 25Kg.
2. This product is hygroscopic, so itis should be sealed and stored in a dry and cool place below35°C.
3. The solid product should beprevented from scattering on the ground because the hygroscopicpowder can cause slipperiness.
