Detailed Product Description
POLYACRYLAMIDE
CAS NO.:9003-05-8
Peculiarity :
Polyacrylamide ,abbreviated as PAM ,is a glassy solid ,apt to sop up water ;the speed of sopping up water varies with different derivative ions .It is soluble in water and organic solvents in acetic acid ,glycol ,glycerin and amine .It will dissolve after long time heating .Dissolving temperature is over 120 .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 ,sugar refining ,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) ,25 kg/bag (Colloid) ,inner bag is PVC film ,outer weaved plastic bag .
