 Propweties:Polyacrylamide,addreviation
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 will dissolve after long time heating.Dissolving
temperature is over 120℃.It carbonates to black powder at
210℃.It carbonates to black power at 210℃ without oxygen.
It could be made to four series,e.g.,non-ion,cation,anion
and mixed cation & anion.
Usages:
It is an important water-soluble compound with the properties
of flocculation,thickening,cut-resisting,block-reducing dispersing,etc..These
properties vary with different derivative ions.So it is widely
used in the field of oil extraction,mining selection,coat
washing, metallurgy, chemical, papermaking,sugarrefining,pharmaceutical,environment
protection,construction materials and agriculture.
Attention to Storage & Transport
No toxicity itself unless over 5‰ is absorbed that will do
harm to stomach. The remains of PAM are poisonous.Strictly
control the dose in food.Avoid moisture in storage & transport.
Package:
25Kg/bag(Powder),25Kg/bag(Colloid),inner bag is PVC film,outer
weaved plastic bag.
