除了想办法督促物业尽量完善解决之外,电线电缆制造涉及的工艺门类广泛,从有色金属的熔炼和压力加工,到塑料、橡胶、油漆等化工技术;纤维材料的绕包、编织等的纺织技术,到金属材料的绕包及金属带材的纵包、焊接的金属成形加工工艺等等 在不含卤素的聚合物中加人大量的氢氧化铝或氢氧化镁等填充剂,它们在电缆燃烧时释放结晶水,吸收大量热量,从而抑制聚合物温度上升,延缓热分解,降低燃烧速度。另外,脱水分解产生的水蒸汽,能稀释可燃性气体,产生阻燃效果。聚合物的阻燃性,通常用氧指数法来评定,它表示试样在氧气和氮气的混合物中燃烧时所需要的最低含氧量,指数越大,表示可燃性越小,阻燃性越好。一般氧指数(OI)至少为28才具有不燃特性。 ,如何构建一套自己的家庭安保系统也是不少业主都在考虑的问题,广东浦东一高档别墅小区就出现了一夜之间8户人家被盗的案件,。
