Product description
Parameters
【Scope of application】
(Patent No.: ZL 2020647116.5) is used to determine the resistance of medical protective masks to penetration of synthetic blood under different test pressures, and can also be used to determine the blood penetration resistance of other coating materials.
【Guideline】
GB 19083, YY/T 0691, YY 0469
[Instrument characteristics]
1. The protruding sample fixing device can simulate the actual use state of the mask, leave the test target area, and does not damage the sample, and distribute the synthetic blood in the target area of the sample.
2. A special constant pressure spray device can spray a certain volume of synthetic blood within a controlled time.
3. It can fully simulate the spray speed corresponding to the average blood pressure of the human body 10.6kPa, 16kPa, and 21.3kPa for testing.
4. It is equipped with a fixed target plate, which can block the high-pressure edge part of the sprayed liquid flow, and only the steady-state flow part is sprayed on the sample, which increases the accuracy and repeatability of the liquid speed sprayed on the sample.
【Technical Parameters】
1. Spraying distance: 300mm～305mm adjustable
2. The nozzle diameter: 0.84mm
3. Jet speed: 450cm/s, 550cm/s, 635cm/s
4. Weight: 35kg
5. Power source: AC220V 50Hz
