一、漂白粉:漂白粉又称含氯石灰,系用气体氯通入熟石灰制成的一种白色粉末,有氯臭,不完全溶于水。漂白粉溶解于水中的次氯酸经分解可放出氯,称有效氯;在水中产生氯愈多,共杀菌力愈强。一般市售漂白粉的有效氯含量在28～35%左右。用作消毒的漂白粉,通常以含有效氯25%为标准,含量低于25%时,应按此例增加用量;如低于15%时,则不适于消毒用。漂白粉在潮湿、高温及阳光照射下易潮解结块,使
First, the bleaching powder: Bleaching powder, also known as chlorine lime, Department of chlorine gas into the cooked lime made of a white powder, chlorine odor, not completely soluble in water. Hypochlorous acid, which is dissolved in water by bleaching powder, can be decomposed to release chlorine, which is called effective chlorine. The more chlorine is produced in water, the stronger the bactericidal power is. The average chlorine content of commercially available bleaching powder is about 28 ~ 35%. For disinfection of bleaching powder, usually containing 25% of the available chlorine as a standard, the content is less than 25%, according to this case to increase the amount; such as less than 15%, then not suitable for disinfection. Bleach in the damp, high temperature and sunlight, easy deliquescence caking
