KF94 mask machine, fish mask machine, willow mask machine.

The correct way to wear products produced by KF94 mask machine, fish mask machine, and willow mask machine:

1. First, loosen the headband every 2-4 cm (only for 8210).

2. Put the mask on the palm of your hand, and put the metal strip on the nose toward your fingertips, so that the headband can sag naturally.

3. Put on a mask with the metal strip on the nose facing up and close to the face.

4. Put the upper headband of the mask behind your head, and then put the lower headband through your head, behind your neck, and adjust it to a comfortable position.

5. Fingertips along the metal strip of the bridge of the nose, slowly press inward from the middle to the sides until it is close to the bridge of the nose.

6. Cover the mask with both hands as much as possible, and perform positive and negative pressure tests. Positive pressure test: Cover the mask with both hands and exhale forcefully. If air overflows from the edge of the mask, that is, it is improperly worn, and the headband and bridging metal strip must be readjusted; negative pressure test: cover the mask with both hands and exhale forcefully. The center of the mask will sink. If air enters from the edge of the mask, it will be worn improperly, and the headband and metal strips of the bridge of the nose need to be readjusted.

As the core material of protective masks, meltblown cloth is known as the "heart" of masks. It has good filtering, shielding, heat insulation and oil absorption, and is the key raw material for the production of KN95 (N95) masks. Its diameter is only one-tenth of the surface fiber of the mask, and it can effectively capture dust. When the virus-infected droplets approach the meltblown cloth, they will also be electrostatically adsorbed on the surface and cannot pass through. I do not know. I was shocked to learn. It turns out that the thin cloth in the middle of the mask is the key factor to protect our lives.
