  • 紫外线消毒灯眼睛防护设备的选择

    一、紫外线消毒的使用和危害 1、紫外线消毒灯的特点。紫外线消毒作为一种常规的空气消毒方法,因其具有操作简便、成本低廉、消毒可靠等优点,在各级医疗机构和居民家庭欢迎和青睐。特别是在新型冠状病毒肆虐以来,这种消毒神器曾一度被抢购一空。但是使用过程中,经常会遇到各种问题,尤其是眼睛保护的问题。 2、紫外灯的分类。消毒使用的紫外线其杀菌作用最强的波段是250~270nm,254 nm为最佳。 2、紫外线消毒灯的危害。主要对人体的伤害表现在对眼睛和皮肤上,尤其是对眼睛的伤害是不可逆的。许多研究表明紫外线消毒如果使用不当也会存在不可忽视的安全隐患,随着紫外线消毒的广泛应用,医院、学校等公共场所常有紫外线灼伤事件的报道,紫外线灼伤可造成暴露者皮肤灼伤、眼睑红肿、结膜充血、畏光、流泪和视物模糊等。导致皮肤过敏、皮肤老化、皮肤肿瘤等等。特点是:皮肤出现红肿、瘙痒、疼痛、红疹等过敏症状。如被强烈的紫外线照射,会出现皮肤老化的现象。而且紫外线中的UVR还会破坏皮肤组织中的胶原纤维,使得皮肤出现皱纹、松弛的现象。紫外线还会影响身体的调节免疫反应诱使皮肤出现癌变,导致黑素瘤、皮肤癌等。紫外线对细菌有强大的杀伤力,对人体同样有一定的伤害,在消毒过程中可谓是“六亲不认”,人体最易受伤的部位是眼睛之眼角膜,因此在任何时候都不可用眼睛直视点亮着的灯管。 二、紫外线消毒时如何做好防护 消毒的房间外应悬挂警示牌,紫外线灯的开关处也应有明显的警示标志。紫外线消毒只能用于无人状态下室内空气的消毒,消毒时需关闭门窗,照射后房间应通风换气。为了保证紫外线的辐照强度,应保持灯管表面清洁,每周用75%酒精擦拭一次,发现灯管表面有灰尘、油污等时,应随时擦拭。为了保护皮肤不受损伤,在执行紫外线检测时应穿长长袖工作服,这样可以保护暴露部位,避免引起皮肤受损。为了保护眼睛不受损伤,应带墨镜或防护面罩做好防护。对于要经常要操作紫外灯的用户,使用正常渠道都买的专业紫外光防护眼镜是有必要的。 三、Laserland T-UV紫外线防护眼镜介绍 本款激光防护眼镜,全部采用德国拜耳PC(聚碳酸酯)原材料,采用欧洲CE和美国FDA标准, 精密配方,精致注塑;镜片防护等级高,外观晶莹剔透,透光清澈;没有光学畸变,没有瑕疵刮痕。 【产品名称】激光防护眼镜 【产品型号】T-UB 【防护波长nm】190-490nm 【典型波长nm】405,445,450,473,UVA 320-400nm,UVB 290-320nm,UVC 200-290nm 【光密度OD】OD4+OD6+ 【可见透光率VLT*】50%,高透过率,在佩戴时不影响看电视,看电脑。 【性能】覆盖200-490nm,紫外到蓝光波段的高达4+,6+光吸收度。视频中完全吸收了影响视力的蓝紫光。防蓝光防辐射 【应用】用于紫外和蓝色半导体激光器件,固体473nm激光器。更适合长期对着电脑工作的上班族使用。特别适合紫外线消毒灯防护,紫外线消毒灯通常为UVC波长,一般消毒灯紫外光波长短,对人眼的伤害是不可逆的。 【样式】本型号可提供7种样式选择。2号外框为标准样式,4号外框为大号外框,适合内戴近视眼镜的朋友。 分享:
