  • 杀菌剂:二硫氰基甲烷 是一种高效广谱性能优良的杀菌剂,对细菌、霉菌、藻类有较强的杀伤能力。用量10~100mg/kg时,其杀菌率为99%,在pH为7时使用效果较好。对工业水中存在的主要细菌、真菌和藻类,以及原生动物都有很好的杀灭和抑止作用,特别是对硫酸盐还原菌十分有效。二硫氰基甲烷属非氧化性杀菌剂,不会由于水系统中有污染物、碎片或其他粒状物而使其活性下降。同时,经水解后毒性降低利于排放。因此,广泛用于工业循环冷却水 (如:大化肥、炼油厂、电厂等)、排污废水、油田注水作杀菌灭藻和粘泥防止剂。还可用于造纸和食品包装的纸板工业中。 水处理杀菌剂又称杀菌灭藻剂、污泥剥离剂,是一种能抑制水中菌藻和微生物的滋长,以防止形成微生物粘泥,对系统造成危害的化学药品。 水处理杀菌剂通常分为两大类:氧化型杀菌剂和非氧化型杀菌剂。前者是一些氧化性很强的氧化剂,对水中微生物杀生作用很强。后者是一些非氧化剂,不以氧化作用杀死微生物,而是以致毒剂作用于微生物的特殊部位起杀生作用。 氧化性杀菌剂,如氯气、次氯酸钠、漂白粉等。 非氧化型杀生剂种类很多,有氯酚类(最常用的是G4),如氯化十二烷基二甲基苄基铵、溴化十二烷基二甲基苄基铵、二硫氰基甲烷等;季铵盐类、有机硫化合物类(常用二硫氰基甲烷)、金属盐类(如硫酸铜)及新型杀生剂异噻唑啉酮等。重金属化合物,如氧化汞、氯化汞、氟化汞等;粘泥杀菌剂,如松香胺、过氧化氢、双胍聚合物等。其中季铵盐类非氧化杀菌剂应用较为广

  • MOL 文件:6317-18-6.mol
  • 杀虫剂增效:很久以前,二硫氰基甲烷已被用于杀菌消毒、木材防腐、杀藻、防垢污等。1979年我国南开大学元素有机所发现本品虽无杀虫活性,但对拟除虫菊酯类杀虫剂具有很高的增效活性,故进行了研究开发。实验研究表明,二硫氰基甲烷与溴氰菊酯、氯氰菊酯、氟氰菊酯、氰戊菊酯、氯菊酯等混用后,增效效果均>50%;其中与溴氰菊酯和氰戊菊酯混用(配比浓度10mg/kg:2.5mg/kg和10mg/kg:5mg/kg),对蚕豆蚜的增效倍数分别达1.07和0.89倍。
