Polyacrylamide series

Polyacrylamide

Polyacrylamide is, simply called PAM, a water- soluble high flocculant polymer and widely used in petroleum, paper-making, metallurgical, textile,sugar refing and environment protection fields. There are three categories of Anionic, Cationic and Non-ionic type. 
Polyacrylamide

Polyacrylamide flocculant CM-415-5 is a water-soluble, linear polymer organic polymer. The product is mainly used in slurry separation and flocculation precipitation of sewage such as papermaking wastewater, pulp wastepaper, textile printing and dyeing wastewater and sugaring wastewater.

Screw metering pump dose the he dissolved CM-415-5 from a tank to every adding point, the dosage can be adjusted according to actual conditions. Agent dissolved concentration is 0.1-0.2%. Dissolution method: add quantitative water to the dissolving tank , the start the agitator, the agitator speed is about 70~100 rmp/min, then slowly dosing the agent(using metering system). Transfer the dissolved agent to the storage tank after it is fully dissolved. The diluted agents should be used as soon as possible and not be preserved for a long time. As the test shows that decomposition may occur after 48 hours and impair the effect of the product.

Advantages of Polyacrylamides:                                                

  • Economical to use - lower dosage levels.

  • Easily soluble in water; dissolves rapidly.

  • Non corrosive of suggested dosage, economical and effective at low levels.

  • Can eliminate the use of alum & further ferric salts when used as primary coagulants.

  • Reduction in sludge of dewatering process system.

Application:
 

Well drilling mud raw materials:

in oil field exploration and development and exploration of geology, water and coal, it is used as adhesive of

well drilling mud raw materials, can improve the service life of drill bits, improve the drill speed and drilling

footage, and reduce plugin replacing drill, and has prominent well slough preventing effect, and it can be used

as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
 

Industrial Waste Water Treatment:

Water sources of many tap water factories come from rivers, the sand and mineral contents are higher, water is muddy,

the water still can not achieve demands although passing through sedimentation and filtration, and flocculating

 agent needs adding; however huge adding amount generates increased mud amount and bad effect. The adding

amount is only 1/50 of inorganic flocculating agent if anionic-polyacrylamide is adopted as flocculating agent,

but the effect is several times better than the organic flocculating agent, and even dozens of times.
 

Textile Auxiliary Agent:

The product can be added with some other chemicals to prepare chemical grout, is used to starch textiles,

can improve the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention performance,

reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, and falling objects.
 

Paper-making adhesive:

The product can be used as fining agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent in paper-making industry


Mine Washing:

The product can be used in coal washing tailing centrifugal separation, can be used in sedimentation and filtration

 of coal powder and coal mud, and can improve the recovery rate of coal powder and the filtration speed.


Sewage Water Treatment:

 When sewage water systems are acidophilic, it is more suitable to select nonionic-polyacrylamide,

the product can be matched with flocculating agent PAC, aluminium sulphate and the like, and it has the best effect in water treatment.


Metallurgical Mineral Dressing:

 It can be used in floatation and smelting of Zinc, manganese  and copper mines, its leachate and slag

can be added into PAM to improve the separation efficiency.


Sand Prevention and Solidification:

 The nonionic-polyacrylamide is dissolved into 0.3% concentration, cross-linking agent is added,

 and the product can be sprayed on desert to prevent and solidify sand.


Chemical mudding agent:

9.5 share nonionic-polyacrylamide is used and is mixed to 0.5share NN-methylene diacrylamide, the product

 can be used as chemical mudding agent for plugging water of dikes, ground foundation, channels and the like.


Oil field profile controlling and water-plugging agent:

The product can be matched with lignocellulose, a certain amount of chemical

adhesive can be added, and the product can be used as oil field profile controlling and water-plugging agent.


Soil humectant:

It can preserve water and solidify sand for soil and can play a role of humectant on slope grass planting, tree planting,

and sand solidification and dust prevention of soil.


Package and Storage:
1.25kg/plastic enhanced paper bags or WHITE PE bags with inner plastic bag
2.Should be stored in original packaging in cool and dry place, away from sources of heat, flame and direct sunlight.
3.Shelf life: 2 years.
