Flame retardant detector mask particle filtration efficiency detector processing

Description :

　　The mask particle filtration efficiency tester is used to test the particle filtration efficiency of daily protective masks and medical masks, as well as to determine the obstruction performance of ordinary fabrics and medical protective masks with respect to constant airflow. Applicable to medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, prevention and control centers, textile testing centers, mask consumption enterprises, etc.

　　Main configuration list of mask particle filtration efficiency detector:

　　1. One host;

　　2. A set of mask testing fixtures, suitable for testing meltblown fabric, flat masks, and three-dimensional masks;

　　3. One set of oil and salt aerosol generators each;

　　4. Laser particle counter;

　　5. Digital gas flowmeter;

　　6. One vacuum pump;

　　7. One needle printer;

　　8. One 7-inch touch screen.

　　The mask particle filtration efficiency tester is used to test the percentage of bacterial suspended particles filtered out by mask materials at a specified flow rate. The use of dual gas path simultaneous comparative sampling method improves the accuracy of sampling and is suitable for performance testing of bacterial filtration efficiency of medical surgical masks by metrological verification departments, research institutes, medical mask production enterprises, and other related departments. Mainly used for metrological verification departments, research institutes, medical mask production enterprises, etc.

　　The detection conditions for the mask particle filtration efficiency tester are: the testing environment temperature is (25 ± 5) C, and the relative humidity is (30 ± 10)%. Testing process:

　　1. Test flow rate (85 ± 4) L/min (if multiple filter elements are used, the flow rate should be evenly divided. If dual filter elements are used, the detection flow rate of each filter element should be (42.5 ± 2) L/mi. If multiple filter elements may be used separately, they should be tested according to the detection conditions of a single filter element). 2. Adjust the filtering efficiency detection system to the detection state and adjust its relevant parameters;

　　2. Use appropriate fixtures to airtightly connect the mouth military body or filter element to the detection device;

　　3. After the testing begins, record the filtration efficiency of the sample with a sampling frequency of 1 time/min. The testing should continue until the particulate matter on the mask is loaded to 30mg; Data processing: Use the small value of the filtration efficiency obtained during the entire testing process as the filtration efficiency of the batch of mask sample materials.
