为确保紫外线灯管的消毒效果,及时更换失去消毒效果的紫外线灯,我们对44支(30W)正在使用的紫外线消毒灯管进行了测试和灭菌效果观察,现将测试结果和灭菌效果报告如下。(一)灯管照射强度测定将紫外线灯管开启2min,于灯管垂直方向1m处,用紫外线强度计测试至指针不动,记录其结果。经测试44支灯管中,照射强度在143μW/cm~2的2支,100μW/cm~2的2支,41μW/cm~2以下的39支,强度为0μW/cm~2的1支。
In order to ensure the disinfection effect of UV lamp and timely replace the UV lamp which has lost the disinfection effect, we conducted the test and sterilization effect on the UV disinfection lamp which is being used by 44 (30W) lamps. Now we report the test results and sterilization results as follows. (A) Determination of lamp irradiation intensity UV lamp open 2min, in the vertical tube 1m Department, with a UV intensity meter test to the pointer does not move, record the results. Tested 44 tubes, the irradiation intensity of 143μW / cm 2 2, 100μW / cm 2 2, 41μW / cm 2 below 39, the intensity of 0μW / cm ~ 2 of a.
