| Abstract:Polyhexamethylene Guanidine hydrochloride (PHGG) presents high antibacterial efficiency for almost all of bacterium in papermaking process, such as Pseudomonas, Aerobacter, Bacillus, proteus and so on. The sterilization rate in white water keeps 80% above in 8 hour at the dosage of 30 mg/L PHGG. Also the PHGG presents high efficiency in eliminating the stickies and pitches and restricts sedimentation of calcium carbonate. In the simulation experiment, more than 50% stickies quantity is removed from the water system when 5% PHGG is used. Using PHGG as bactericide and aggradation control agent in the production line, the paper machine becomes more clean and runs more smoothly. |
