Paper Industry Polyacrylamide can be used for paper making industry to improve the dry and wet strength, increase stability of pulp, enhance the staying rate of filling material and speed size filterability in the paper.
Dry strength agent is used in paper mill to increase the strength of paper. Moreover, paper dry strength agent increase the the strength of paper by increasing the internal bond formation and improves bust strength, tear strength, wax pick values, folding endurance, stiffnes , increase levels of paper fillers uses etc.
RESULTS AND DISCUSSION In table 1 the quantities of proteins coupled to glutaraldehyde-activated polyacrylamide-agarose beads (AcA34) using various concentrations of proteins and beads are given. Under the conditions described, 0.4 to 2.0 mg of proteins per ml of polyacrylamide-agarose gel were found to be fixed.
The beads were then washed 5 times with 1 ml Tris-Buffered Saline (TBS: 50 mM Tris-HCl, pH 7.5; 150 mM NaCl) per wash to remove any unbound proteins and stored in TBS as a 50% suspension at 4 掳C.
anionic polyacrylamide cas no 9003-05-8 adopts the homopolymerization of acrylamide before adding alkali hydrolysis.After granulating,dring,pulverizing,the appearance of the product is white granule powder.The product will be better used in sewage treatment,especially for wastewater from iron and steel plant,electroplating,metallurgical and coal factory.
Description. Anionic polyacrylamide is the kind of wastewater treatment chemicals which is water-soluble linear polymer synthesized with high degree of polymerization.Anionic polyacrylamide powder is easily soluble in water and almost insoluble in common organic solvents such as benzene, ether, lipids and acetone. Anionic polyacrylamide molecular chain contains a certain amount of polar groups
