【摘要】 研究了聚六亚甲基盐酸胍(PHGC)对造纸工业常见的微生物的杀抑菌性能和应用效果。结果表明:30 mg/L用量的PHGC在白水水样中的静态杀菌试验中,8 h内的杀菌率都保持80%以上。PHGC同时具有消除胶黏物质的功能,5%用量PHGC可以使残留在滤网上的胶黏物质减少50%以上,同时滤液也变得更加澄清。在纸机生产应用中,使用PHGC作为造纸杀菌剂和沉积物控制剂,可有效降低白水的微生物水平,延长了纸机清洗周期,实验过程中纸机稳定运行,没有因为腐浆出现断纸等现象,效果优于进口杀菌剂。更多还原

【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.更多还原
