Disposable Medical Mask Flame Retardant Tester operation process

Mask Flame Retardant Tester operation process:

1, plug into the power socket on the back cover of the instrument to turn on the power, counterclockwise to the gas cylinder with the random gas pressure reducing valve twist to open the cylinder valve to turn on the gas source.


2, the front door of the combustion test chamber closed, and the "power" switch placed in the "open" position, the power indicator light.

3, first make the metal head mold nose tip part down, the mouthpiece with the metal head mold, press the "head mold start" button, the head mold began to rotate, when the head mold nose tip part just above the igniter, press the "negative combustion stop" button, so that the head mold stop rotating Adjust the height of the igniter head (rotate the igniter head clockwise to lower it and counterclockwise to raise it) so that the distance between the top of the igniter and the tip of the head is 20±2mm;


4, press the "igniter return" button to make the burner back to the ignition position.


5、Press the "Head return" button to return the head to the starting position. Press the "zero" button, the instrument is back to the initial state.


6, keep pressing the "ignition" button, adjust the "pressure adjustment" knob on the panel (first gently pull up to the outside, and then follow the instructions on the end of the knob to rotate in the "+" direction to increase, and in the "-" direction to increase. "-" direction rotation for decrease to adjust), so that the top of the instrument case pressure gauge pointer pointed at 20Kpa, and then press the knob to lock the pressure. (factory has been adjusted)


7, at this point the ignition resistance wire has become red, to ignite the igniter and then release the "ignition" button. When ignition is difficult, please adjust the "flame" adjustment button, clockwise to reduce the flow of combustible gas, counterclockwise to increase the flow of combustible gas.

A mask test in Japan: wearing this way, the “leakage” rate of external bacteria is 100%

Masks can help us block the virus, but if they are taken off and worn improperly, their protective effect will be greatly reduced. A program on MBS TV in Japan did a test and found that the wrong way to wear the mask will greatly reduce the filtering effect of the mask. Here are the 4 most common mistakes in taking off and wearing masks, and teach you how to use them correctly to make masks more effective in protection. 4 wrong ways to take off masks: 1. Does not fit the face completely There is a gap between the mask and the face, and when a person breathes, the airflow will flow to the gap. This program on Japanese MBS TV had a woman wear a mask that did not fit her face. Doctors use special equipment to measure the probability of harmful substances in the air on the outside of the mask entering the inside of the mask through the gap. The test found that the external bacteria leakage rate reached 100%. That is to say, there is a gap between the mask and the face, which will seriously...

Advantages of QINSUN protective clothing Antisynthetic blood penetration tester QINSUN protective clothing Antisynthetic blood penetration tester test principle： Through the micro flow pump, see-through type constant temperature water bath, water bath type measurement chamber to form a closed-loop loop, the sample through the split flange clamped in the middle of the measurement chamber and trapping chamber, the sample placed on both sides of the tetrafluoroethylene gasket, split flange and measurement cell contact position installed with silicone executive ring and protective gasket, operation by adding the chemical to be measured to the measurement chamber, the chemical through the sample penetration to the trapping chamber complementary trapping liquid captured and with In principle, the flow rate should not be too large or too small, but about 5 times the volume of the trapping liquid, which is calculated by the analysis electrode. QINSUN protective clothing Antisynthetic blood pen...
