Test principle: This equipment sprays the pre-prepared NaCl solution or DEHS / PAO and other similar solutions from the aerosol generator through clean compressed air. After passing through a classifier (inertia principle), the large particles that are not needed are collected into the collection bottle. Aerosol particles that meet the requirements are ejected from the nozzle of the aerosol generator into the test system. 1. The aerosol emitted by the aerosol generator needs to be processed twice before reaching the test filter; ① Produce aerosol salt particles by mixing with heated gas (for salt mist). ② The static electricity carried by the aerosol is neutralized by an electrostatic neutralizer. This action is to reduce the loss of particles and the influence of static electricity on the test results. 2. After being processed by the above two procedures, the aerosol reaches the surface of the test filter material at a certain flow rate (flow rate) and begins the test procedure. For the filtration efficiency test, the test time is very short, and it takes only a few seconds to complete the Test of filter material. For the loading experiment, the test experiment is relatively long. The particle concentration or the mass concentration of the aerosol upstream and downstream of the filter material is measured by a particle counter or a laser scattering photometer, and the filtration efficiency is calculated. Conduct monitoring.

Instrument characteristics:

1. Intelligent touch screen control + test report printing PLC control system, more efficient and reliable, programmable 7-inch color LCD touch screen, to achieve control, monitoring, calculation, data display and other functions. 2. A variety of test fixtures The instrument has a variety of test fixtures that can test different types of masks 3. High degree of automation The equipment is designed as a dual-control pneumatic clamping method, which is easy to operate and has high safety. 4. Powerful built-in equipment The device can test penetration efficiency, penetration resistance and flow rate. At the same time, the flow pressure difference of the device can be set arbitrarily, satisfying a variety of experiments, stable performance, and good repeatability of test data.
