Polyacrylamide
Properties:
Polyacrylamide, abbreviation PAM,is a glassy solid.The
speed of absorbing water varless with different derivative.it
is soluble in watert and organic solvents,such as acetic
acid,glycol,glycerin and amine,it melts after long time
heating dissoiving temperature is over 200℃,it
carbonates to black powder at 210℃ without oxyen.
It could be made to four series e g,mon-ion,cation anion
and mixed cation & anion.
Usages:
It is an important water-soluble polymer
with the properties flocculating,thickening,cut-resisting,block-reducing
dispersing,etc.These properties vary with different
derivative ions soitis widely used in the field of lil
extraction,mining selection,coat washing,metallurgy,cheical,papermaking,sugarrfining,pharmaceutical,envionment
protection,construction materials and agricrlture.
Storage
& Transport: No toxicity unless
over 5% is absorbed that will do harm to stomach.The
residue acrylamide is Toric.If is strictly controlled
for food application.Avoid moisture in storeage &
transport.
Package:
25kg/bag(powder),25kg/bag(colloid) inner bag is PVC
film,outer wover plastic bag. Technic Index: Powder
