    问:防静电工作服的作用有哪些?


    发布时间:2014-08-15 09:13:00 点击:

    答:防静电工作服可有效地抑制服装静电,消除或减小静电放电危害。人体在进行各种活动时服装上的静电压值已大大超过许多静电敏感器件的静电放电损坏阈值,那么在触及或接近这些元器件时就有可能造成敏感器件损坏。还需指出,一般认为穿纯棉工作服可防止服装静电积累,因而就安全。实际这种观点具有片面性,只有当空气相对湿度高于50%时才基本如此;而当相对湿度比较低时,纯棉制品的带电量明显增大。试验表明,在相对湿度低于30%时,纯棉织物的带电量与涤纶相当;而当相对湿度低于20%时,棉织物的带电量甚至会高于某些化纤织物。所以在气候干燥地区,不能指望在任何情况下都能用纯棉制品消除服装静电危害。基于以上原因,为有效防止人体静电的静电放电危害,操作者必须穿用防静电工作制服。

    A: Anti-static work uniforms clothing can effectively suppress static, eliminate or reduce static discharge hazards. When carrying out a variety of human activities on static voltage value clothing has greatly exceeded many of electrostatic sensitive devices to electrostatic discharge damage threshold, then it may cause damage to sensitive devices when touched or near these components. Should also be noted, is generally believed to wear work uniforms cotton clothing to prevent accumulation of static electricity, which is safety. This view has a real one-sidedness, only when the relative humidity is higher than 50% nearly so; but when the relative humidity is relatively low, cotton products, with power increased significantly. Tests showed that when the relative humidity is below 30%, cotton and polyester fabric with considerable power; but when the relative humidity is below 20%, cotton fabric with a power even higher than some synthetic fabrics. So dry climate regions, can not be expected in any case can use cotton clothing products to eliminate static electricity hazards. For these reasons, in order to prevent harm to human electrostatic discharge of static electricity, the operator must wear an antistatic work uniforms.
