Introduction of polyacrylamide

 

Polyacrylamide (PAM) is divided into anionic polyacrylamide, cationic polyacrylamide. Amphoteric ionic polyacrylamide, non ionic polyacrylamide. It is a kind of water-soluble linear polymer which is polymerized by monomer acrylamide. The appearance of the product is white powder, soluble in water, almost insoluble in benzene, ether, ester, acetone and other general organic solvents, its aqueous solution is nearly transparent viscous liquid, is non-dangerous, non-toxic, non-corrosive, solid PAM has hygroscopicity, The hygroscopicity increases with the increase of ionic degree.

 

 Screening of Polyacrylamide

 

Purpose of screening: to remove small particles from granulation products to ensure that they look good and meet the requirements of finished products!

1.Production process: granulation (at this point the product is like the white particle of soybean)-into the crusher-to carry out the required screening.
2.Some of the broken polyacrylamide looks like crude salt, is irregular granular, moist and less corrosive; 3, the number of mesh screened is: 16 mesh, 24 mesh, 40 mesh, 60 mesh, 80 mesh; screen standard B
3.The number of sieving is: 16, 24, 40, 60, 80, et al.
4.Purpose of screening : simple classification , there is no strict requirement for the size of the screen , and the screen can have upper and lower 2 - purpose deviations;
5.Most of the equipment uses two sieve mesh three outlet, at this time the middle is the finished product, the top coarse material into the second crushing; there is also a part of the use of a layer, the thickness of the finished product or fine part for the finished product;
6.The matters to be paid attention to the equipment: above 60 mesh the use of stamping mesh thick wire mesh screen is the best, because this material is corrosive, submother network customers do not like the product * if the customer is to granular finished product, the middle sieve outlet has 5mm material layer as the best state; * single industry requirements, equipment material carbon steel 304 stainless steel can be, according to the material characteristics 304 best.

 

 

Polyacrylamide action

 

1.Flocculation: PAM can flocculate suspensions through electric neutralization, bridging adsorption and flocculation.
-because of this property, it is often used as a purifying agent to flocculate impurities in the treatment of water and thus to purify them.
2.Adhesion: the ability to bond through mechanical, physical, and chemical action.
-this property is also one of the raw materials for paper, products, and petroleum auxiliaries.
3.Drag reduction: PAM can effectively reduce the friction resistance of the fluid. Adding a small amount of PAM in water can reduce the resistance of 50-80.
- the characteristics of water in the water.
4.Thickening: PAM has thickening effect under both neutral and acid conditions. When PH value is above 10 ℃, PAM is easy to hydrolyze. The thickening will be more obvious when the semi-reticular structure is present.
-the characteristics of thickening and adhesion.

 

Application of anionic polyacrylamide

 

1 . Mainly used as flocculating agent : for suspended particles , coarse , high concentration , positive charge of particles , PH value of water as neutral or alkaline waste water , because the anionic polyacrylamide molecular chain contains a certain amount of polar group capable of absorbing suspended solid particles in water , it can accelerate the settling of the solution , promote filtration and the like . The product is widely used in the treatment of chemical industrial waste water , waste liquid , municipal sewage treatment , tap water industry , high turbidity water purification , settling , coal washing , dressing , metallurgy , iron and steel industry , zinc , aluminum processing industry and electronic work . Industry and other water treatment.
2.It is widely used in petroleum industry, oil recovery, drilling mud, waste mud treatment, preventing water channeling, reducing friction, improving oil recovery.
3.It is used for textile sizing agent with stable slurry performance, less pulp, low fabric breakage and smooth cloth.
4.For paper industry, one is to improve the retention rate of fillers, pigments, etc. To reduce the loss of raw materials and pollution to the environment; second, to increase the strength of paper (including dry and wet strength) and, in addition, to use PAM to improve the tear resistance and porosity of paper to improve its visual and printing properties, Also used in food and tea wrapping paper.
5.Other industries, food industry, sugar cane sugar, sugar production sugar juice clarification and syrup phosphorus floatation extraction. Enzyme fermentation broth flocculation clarification industry, also used for the recovery of feed protein, quality stability, good performance, the recovered protein powder on chicken survival rate and weight gain, no adverse effect on egg production, synthetic resin paint, civil grouting materials water shutoff, Building materials industry, improve cement quality, construction adhesives, joint repair and water shutoff agent, soil improvement, electroplating industry, printing and dyeing industry.

 

Application of cationic polyacrylamide

 

Cationic polyacrylamide (CPAM) exhibits positive electrical properties in acidic or alkaline media, and its molecular weight is usually lower than that of anionic or Nonionic polyacrylamide (Nonionic polyacrylamide). The properties of cationic polyacrylamide are mainly obtained by charge neutralization. This kind of flocculant has the function of removing turbidity and decolorizing. In alcohol plants, monosodium glutamate plants, sugar mills, meat factories, beverage factories, printing and dyeing factories, the use of cationic polyacrylamide is several or tens of times higher than that of anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt.Because this kind of wastewater generally has negative charge, cationic polyacrylamide is suitable for high speed centrifuge, belt filter press, plate filter press and other special sludge dewatering machinery. Good agglomeration, easy to peel off the filter cloth and other characteristics. So the dehydration rate is high, the filter cake contains low liquid, the consumption is low, can greatly reduce the user's use cost. Can also be used in hydrochloric acid, medium concentration of sulfuric acid and other liquids, separation and purification of suspended substances contained therein. Therefore, the product is widely used in municipal wastewater treatment plants, breweries, food plants, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and chemical industry. Makeup and other sludge dewatering treatment.
