Flame retardant detector, intelligent particle detector

Description :

　　The application scope of the mask particle filtration efficiency detector is:

　　The mask particle filtration efficiency detector is suitable for medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, mask and respirator production enterprises, etc.

　　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.

　　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.

　　The working principle of the mask particle filtration efficiency detector is:

　　The composition and principle of the mask particle filtration efficiency tester equipment include an oil mist generator, data acquisition software, detection product tooling device, concentration detector, filtered concentration detector, computer data calculation device, pressure regulation device, and tooling pipeline testing device. The photometer in the system is used to detect the concentration of the mask before and after filtration, thus completing the detection of the protective efficiency of the mask particles.
