6-18 million 2012 hot sale Anionic polyacrylamide/PHPA
Tip1: Soil Conditioner
The primary functions of Polyacrylamide Soil Conditioners are to increase soil tilth, aeration, and porosity and reduce compaction, dustiness and water run-off. Secondary functions are to increase plant vigor, color, appearance, rooting depth and emergence of seeds while decreasing water requirements, diseases, erosion and maintenance expenses.

tip2: how to choose polyacrylamide (PAM)
at first ,you need know the kind of PAM.
learn about its kind.
PAM kinds:
According to the characteristics of ions:
anionic PAM , cationic PAM, Nonionic PAM. amphiprotic PAM.
According to the molecular weight: 2-22 million
2 million PAM
6 million PAM
9 million PAM
12 million PAM
15 million PAM
18 million PAM
22 milliom PAM
way of identify quality :
Polyacrylamide has certain viscosity, it can be distinguished by hand touch feeling, the viscosity of the better, the better the quality .
to more accurate, use chemical way to test molecular weight.
how to choose a proper PAM for ourselves
The specific choice that type according to the different sewage .the best way is to go through the scene collecting sewage samples, test to determine. if you can't trust your supplier , you can test yourself. it is easy experiment.
Cationic polyacrylamide
Features
PAM molecular chains fix on different surfaces of particles bettween that polymer bridges were formed, which makes aggregates of particles form and settle .it has function of surface adsorption the porlar groups of PAM molecule have adsorption for particles with opposite polar chargesPAM molecular chains will link the dispersed particles and form it to network –lile so as to enhance its treatment funtion.Application
used to industries wastewater treatment of electroplating . circuit board. Paper making . printing&dyeing. Bleaching&dyeing and tanning etc.used for urban life sewage purification used for tap water purification etc.used for drying of sludge dewateringQuality specification
