Chinese Mask Filter Detector Manufacturer - Chinaprice: 1.00 Dollar US$
Chinese mask filter detector manufacturer 1 - Overview SX-L1056 filter material efficiency test bench, suitable for testing the efficiency of 40-99.999% masks, and test masks according to international standards.
The design structure of the whole test bench is compact and light.
In the process of running and testing, it only needs to provide additional suitable power supply and compressed air (no water, no oil), which is suitable for use in laboratories, factories and other occasions.
Fix the finished product on the fixture, and the test air volume corresponds to the required filtration speed.
The aerosol produced by the aerosol generator is adjusted, and then the aerosol is electrostatically neutralized, and then uniformly mixed with the filtered test air, and then enters the test area to penetrate the filter material.
In order to measure the efficiency, one air split is drawn upstream and downstream of the mask.
Use a photometer to measure the concentration of particles in the sampling airflow, and pass the ratio between upstream and downstream, and then obtain the measured efficiency.
In addition, it is necessary to measure the resistance of the filter material during the test and adjust the control flow rate.
Reference standard: GB/T 32610-2016 Technical specifications for daily protective masks GB 2626-2006 Respiratory protective equipment-self-priming filter particulate respirators GB Technical requirements for medical disposable protective clothing GB Technical requirements for medical protective masks YY 0969-2013 Once Sexual use medical mask YY 0469-2011 medical surgical mask 2 - Main components 1 - Aerosol generator Nacl (KCl) aerosol generator, DEHS aerosol generator 2 - The photometer is mainly used to monitor the upstream and downstream particle concentration of the tested filter material to obtain the measured filter material efficient.
3 - The pressure difference sensor is mainly used to test the pressure difference (or resistance) of the tested filter material under a certain test flow.
4 - The stainless steel fixture is mainly used for the compression and sealing of the tested filter material.
5 - The exhaust fan is mainly used for the test flow through the filter material, the flow is stable, green and energy-saving, and low vibration and noise.
6 - Circuit control and operation of electrical control and software equipment, calculation and data processing of software, stability judgment of upstream concentration, operation control, parameter setting.
3 - Function description The test bench mainly tests the filtration efficiency and airflow resistance of filter materials and masks.
It can test GB 2626-2006 mask particle filtration efficiency, GB/T 32610-2016 filtration efficiency and protection effect test GB 19082-2009 GB 19083-2010 filtration efficiency and resistance YY 0969-2013 YY 0469-2011 particle filtration efficiency and resistance, etc.
If there is a separate personalized function, it can be customized according to specific needs.
