Harmful properties of the use of Halogens 使用卤素的有害性? - Carcinogenic 致癌 - Release toxic gas when combusion: Dioxin/Furan 燃烧时释放有毒气体, 二恶因和呋喃 - Toxic for immunity system, and effect incretion system, toxic for reproduction 免疫系统毒性、内分泌系统影响、对生殖系统的毒害 - Mutagenic 诱导有机体突变 - Most of halogen substances are environmental hormone substance 大部分卤素化合物都是环境荷尔蒙物质 ‘Halogen – Free’ materials or products -- A new trend in E E industry ‘无卤’ 材料及产品 -- 电子电气行业新趋势 Halogen-free products have been available for quite some time and its use is expected to increase. This increase is driven by industry initiatives and legislation aimed at protecting the environment. Most famous manufacturers such as DELL, SONY, Matsushita and NTT have set up green procurement policies. Besides, EU RoHS,etc regulations restricted the some halogen substances used in certain electrical and electric equipments. 无卤产品已经启用了很长一段时间了，而且它的使用量有望继续增长。行业创新和环境保护的法律将继续推动该增长。大多数著名的制造商如DELL,索尼,松下和NNT都已经建立了绿色通道政策。另外，欧盟RoHS指令等法规也限制一些卤素物质在某些电子电气设备中的使用. Halogen 卤素 A halogen is defined as an element in group VII of periodic table, including Fluorine, Chlorine, Bromine, Iodine, Astatine. 卤素是化学元素周期表中第七族的元素，包括了氟、氯、溴、碘、砹。 Astatine is a radioelement, so in general, halogen is defined as Fluorine, Chlorine, Bromine, Iodine. 砹是放射性元素，所以一般卤素质的只是氟、氯、溴、碘。 Usage of Halogen in industry 工业上卤素的用途 Halogen is used as flame retardants, refrigeration, vesicant, solvents, organic chemical industrial raw materials, dye stuff, organic pest
