Polyacrylamide (PAM)

详情

Properties: Polyacrylamide (PAM) is one kind of glass-like solid.
Following your demands, Polyacrylamide can be made into 4 types: non-ion, anion, cation and mixture of cation and anion.
Uses: Polyacrylamide is an important water-soluble polymer, and the combination advantages of flocculation, thickening, shearing, drop resistance and dispensability; thus, it is widely used in oil drilling, mineral processing, metallurgy, chemicals, paper, textile, sugar, medicine, environmental protection, building materials, agricultural production ad so on.
Storage, transportation and cautions: Polyacrylamide is a non-toxic matter. The residual acrylamide monomer in Polyacrylamide is toxic, so it should be used in food with cautions. Avoid moisture.
Packing: dry powder *5kg/bag; plastic bag lined woven bag or kraft paper bag.

Mark ,Package, Transportation, Storage:
Outer bags should be printed fixed and clear marks, including: Factory name, Product name, Type, Trademark, Batch or producing date, Net content, Factory address and stipulated in GB /T **1: " To be protected from heat. "  and  Picture 6 Afraid of Rain.
Each batch of Polyacrylamide should be attached with Quality Certification, including: Factory name, Product name, Type, Trademark, batch or producing date, Net content, Certification of Analysis and Standard number.
 Water treatment agent of Polyacrylamide should be double packed. Inner is Polyethylene film bag, thickness is not less than0.*5mm, and inner packing volume should be bigger than outer packing; Outer is Polyethylene plastic woven bag, the characteristic and test methods should be on the base of GB/T ***5. Net weight of bag: *5kg, *0kg (or required as customer demands)
There should be covering in the transportation, the polyacrylamide shall be sealed and stored in the cool, dry and ventilated place to prevent from rain, high temperature and strong sunlight.
Shelf life: two years under correct storage.
