Used to determine the resistance of medical protective masks to penetration by synthetic blood at different test pressures.
Can also be used to determine the resistance to blood penetration of other coating materials.
Specifications
Injection distance: 300 to 305 mm (adjustable).
Nozzle diameter: 0.84 mm.
Jet velocity: 4500, 5500, 6350 mm.
2A special jet device with constant pressure can spray a certain volume of synthetic blood in a controlled time.
Can fully simulate the corresponding injection rate to test under the average blood pressure of the human body at 10.6 kPa, 16 kPa, 21.3 kPa.
Design Features
The protruding sample fixture can simulate the actual use condition of the mask.
Reserves the test target area without destroying the sample, and distributes synthetic blood in the sample target area.
The fixed target plate can block high pressure part of the injected liquid flow to allow steady flow to be sprayed to the sample, increasing the accuracy and repeatability of liquid spraying speed.
