YYT-07B Respirator Flame Retardant Tester
The flame retardant tester for respirator is developed according to gb2626 respiratory protective equipment, which is used to test the fire resistance and flame retardant performance of respirators. The applicable standards are: gb2626 respiratory protective articles, gb19082 technical requirements for disposable medical protective clothing, gb19083 technical requirements for medical protective masks, and gb32610 technical specification for daily protective masks Yy0469 medical surgical mask, yyt0969 disposable medical mask, etc.
1. The mask head mold is made of metal material, and the facial features are simulated according to the ratio of 1:1
2. PLC touch screen + PLC control, to achieve control / detection / calculation / data display / historical data query multi-function
3. Touch screen:
a. Size: 7 "effective display size: 15.41cm long and 8.59cm wide;
b. Resolution: 480 * 480
c. Communication interface: RS232, 3.3V CMOS or TTL, serial port mode
d. Storage capacity: 1g
e. Using pure hardware FPGA drive display, "zero" start-up time, power on can run
f. Using m3 + FPGA architecture, m3 is responsible for instruction parsing, FPGA focuses on TFT display to ensure speed and reliability
4. The burner height can be adjusted
5. Automatic positioning and timing
6. Display the afterburning time
7. Equipped with flame sensor
8. Head mold movement speed (60 ± 5) mm / s
9. The diameter of flame temperature probe is 1.5mm
10. Flame temperature adjustment range: 750-950 ℃
11. The accuracy of afterburning time is 0.1s
12. Power supply: 220 V, 50 Hz
13. Gas: propane or LPG
Test interface
1. Click directly to the top of the lamp to adjust the distance from the nozzle to the lower die
2. Start: the head mold starts to move towards the blowtorch direction and stops at another position through the blowtorch
3. Exhaust: turn on / off the exhaust fan on the box →
4. Gas: open / close gas channel
5. Ignition: start the high pressure ignition device
6. Lighting: turn on / off the lamp in the box
7. Save: save the test data after the test
8. Timing: record the afterburning time
