一种防电弧面料及其制备方法、应用
技术领域
本发明属于纺织品技术领域,具体涉及一种防电弧面料及其制备方法、应用。
背景技术
电弧伤,一般是指人体在没有接触电流时,由于人在有电的环境周围遭遇到电在电离空气时产生的巨大电弧热而引起的电弧热烧伤;而其他电损伤往往更多的是由于人体直接接触到电源电流而导致的内外人体组织的破坏性损伤。电弧危险往往与其他电损伤不同,它经常是无需接触还容易被疏忽、难以避免,直接接触点燃的衣物会造成工人的严重烧伤或死亡。
随着工业的快速发展,出现了越来越多的电弧伤害事故,面对事故的多发,如果工作人员穿着具有防火及热防护性能的服装,其遭受的伤害就越小,防电弧面料制备而成的服装,有效的解决了长期困扰在电力、化工等行业工作人员的安全问题,大大的降低了电弧对工作人员的伤害概率。
防电弧面料的防护效果是基于电弧放电的原理,该系列的面料具有耐热、阻燃、不助燃、不熔融和H级电绝缘等永久性的防火、绝缘等特点。在电弧爆炸发生时,这种面料会迅速膨胀、织物炭化从而组织密度加大并便后,迅速地形成保护层,从而使得人体皮肤与电弧热能的伤害降至最低。目前,防电弧面料存在水洗一定次数后,存在炭化不完全,导致某些部位仍易被电弧伤害,且易发霉产生病菌。
