Polyacrylamid

Description

Propweties:Polyacrylamide, addreviation PAM, is a glassy solid, apt to water absorbing;the speed of absorbing water varies with different derivative ***** is soluble in water and organic solvents as acetic acid, glycol, glycerin and ***** will dissolve after long time heating.Dissolving temperature is over ***** carbonates to black powder at ***** carbonates to black power at **0oC without oxygen. It could be made to four series, *****, 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, ***** 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: *5Kg/bag(Powder), *5Kg/bag(Colloid), inner bag is PVC film, outer weaved plastic bag. 1.Power Items Index No-ion Cation Anion Appearance White or light Yellow particle White or light Yellow particle White or light Yellow particle Solid content≥% *0 *0 *0 Molecular weight *******0 ********0 ******0 Free substance≤% 0.5 0.5 0.5 Time for water-soluble(h) **5 0.**2 0.**1 Hydrolysis rate% ≤5 ****5 Cation ***0 ***** Items Index No-ion Cation Anion Appearance White colloid White colloid White colloid Solid content≥% ***0 ***0 ***0 Solid content≥% ******0 ******0 ******0 Free substance≤% 0.5 0.5 0.5 Hydrolysis rate% ≤5 ***0 Cation ***0
