How to distinguish the front and back of a copper mask
? Why do we correctly distinguish the front and back of the mask? Many people may think that as long as you wear a Shishi, the front and back are the same. This is not the case. The front and back of the copper mask have different functions. Many masks use a three-layer design. The filter layer for filtering bacteria is located in the middle, the outer layer is a waterproof layer, and the inner layer is a water-absorbing layer. If worn back, the water-absorbing layer will become a waterproof layer, and the waterproof layer will become a water-absorbing layer. This will cause saliva to adhere to the surface of the mask, and the more saliva accumulates, it may wet the mask and make the mask lose its filtering function. How to distinguish the front and back of the mask So how to distinguish the front and back of the mask? First, distinguish the top and bottom, the metal strip is on the top, because the metal strip can be used to adjust to fit the nose. After determining the above conditions, let us determine which side is the outside and which side is the inside. I have listed the characteristics of several common disposable masks. You can judge by checking the numbers. Judging by color usually, what we see is a blue medical copper mask, the blue side is the outside, and the light (white) side is the inside (face). Judgment by printing If the logo or brand name is printed on the copper mask, it is easy to judge. The embossing of the logo or brand name is usually printed on the outside, and then you can know if the word is correct. This can also be seen from the logos in the two pictures above. It can be judged by the direction of the crease. If the mask you buy is pure white, nothing is printed on it. Font, what to do? It doesn't matter, we have a final way of judging: observe the direction of the folds! There are two types of folds in masks: four folds and one with four folds, which is easier to judge. You open it naturally, and one side in the middle is convex, so that side is the outside. In fact, it's easy to understand when you think about it. This gives our mouth and nose a certain amount of breathing space. After stretching, the direction of the upper two folds is upward, and the direction of the lower two folds is downward. Abstract First, it can be judged by color: the dark color is on the outside and the light color is on the inside; second, it can be judged by printing. The printing is usually on the outside and the word is affirmative. If you buy an unprinted pure white mask, you can judge according to the folding direction. If there are three folds, the direction of the crease is downward; if there are four folds, the middle part protrudes outward after unfolding, that is, the outside. In addition, after unfolding, the two-fold direction of the upper part is upward, and the two-fold direction of the lower part is downward. Finally, we can also distinguish the front and back by the metal band. The protruding side of the metal rod is the outside, and the flat side of the metal rod is the inside.copper fabric clothing
