紫外线是目前常用的物理消毒方法之一,广泛用于医院空气消毒,但因使用不当常会影响消毒效果。但关于电压对紫外线消毒的影响有多大,至今未引起重视,采用不同电压对新旧紫外线灯管辐照强度进行测试,监测结果报告如下。1 材料方法 根据测试条件,温度30℃,相对湿度50％,取新旧(旧灯管使用小时数为200～300小时)紫外线灯管各20支,依次编号,电压在180 V～220 V之间,以10 V为一档逐级测试,数据分别取新旧灯管1～10号和11～20号灯管的平均值。2 结果与讨论 通过测试我们发现电压的高低对紫外线灯管辐照强度影响
UV is one of the commonly used methods of physical disinfection, widely used in hospital air disinfection, but improper use often affect the disinfection effect. However, the voltage on the UV disinfection how much, so far no attention, using different voltage on the old and new UV lamp irradiation intensity test results are reported below. 1 Materials Method According to the test conditions, the temperature 30 ℃, relative humidity 50%, take old (old lamp hours 200 to 300 hours) UV lamp 20, followed by the number of voltage between 180 V ~ 220 V , To 10 V as a file level by level test, the data were taken for the old lamp 1 to 10 and 11 to 20, the average of the lamp. 2 Results and Discussion Through the test we found that the voltage level of UV lamp irradiation intensity
