Product description

addreviation PAM, is a water soluble macromolecular polymer.
PAM is a glassy solid, apt to water absorbing, the speed of absorbing water varies with different derivative ions.
It is soluble in water and organic solvents as acetic acid, glycol, glycerin and amine. It generates a good flocculation and can decrease the resistance between liquids. It will dissolve after long time heating. Dissolcing temperature is to over120oC. It carbonates to black powder at 210oC without oxygen.
According clients’s requirment, PAM can be made to four series,eg: non-iron,cation, anion, anion and mixed cation & anion.

Type

Application range

Cationic type

1.It is mainly used for the sludge dewatering and decrease the rate of water content of sludge.
2.It can also be used to treat industrial wastewater and life sewage water.
3.It can be used for papermaking to improve dry and wet strength of paper and to improve dry and wet strength of paper and to increase the reservation of tiny fibers and fillings.

Anionic type

1. It is mainly used for Enhanced Oil Recovery to increase the efficiency of oil recovery of tertiary floods..By intoducing viscous polymer solutions to the flood the efficiency of the volumetric sweep is increased, channelling and breakthrough is decreased thereby having the overall effect of increasing the oil recovered.
2. It can also be used to treat industrial wastewaters and mining wastewaters.
3 It can be used for dry strength resin in paper making industry.

Nonionic type

1.It is mainly used to recycle the wastewater from clay producing.
2.It can also be  used to centrifugalize the tailings of coal washing and filter the fine particles of iron ore.
3.It can also be used to treat industrial wastewaters.

Attention to the use of methods and matters

1.The product should be prepared for the water solution of 0.1%-0.4% 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 60oC).
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.

Storage and packing

1.The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.The colloidal product can be packed in inner plastic bags and further in fiber plate drums with each drum containing 50Kg or 200Kg.
2.This product is hygroscopic, so it is should be sealed and stored in a dry and cool place below 35oC.
3.The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.
