Feb. 26, 2020

1. Encyclopedia of medical masks: Disposable face mask is composed of mask face and tension band. The mask face is divided into inner, middle and outer layers, the inner layer is skin-friendly material, the middle layer is an isolation filter layer, and the outer layer is special Material antibacterial layer. This highly effective medical mask is highly hydrophobic and breathable, and has a significant filtering effect on micro-band virus aerosols or harmful dust, but cannot effectively filter PM10 and PM2.5. The overall filtering effect is good, and the materials used are non-toxic and harmless to wear and comfortable.

Summary: Blue masks are mainly bacterial viruses, but they cannot prevent smog (that is, doctors and nurses still need cotton masks or 3M when they leave the hospital), so they are mainly used in hospitals.

2. Cotton masks, both homemade and bought, are also very common in China, and can be washed repeatedly, always carried, and have good breathability. The disadvantage is that the protection ratio is relatively low (see the cotton material and the number of layers).

Summary: If the elderly and children need to stay out for a long time, this is the only option, because their cardiopulmonary function is not enough, and they can not wear a mask with poor ventilation for a long time. (Of course, you ca n’t bring too thick for a long time)

3. Encyclopedia introduction of bamboo charcoal masks: bamboo charcoal fiber is made from moso bamboo, and adopts a new process and technology of calcination with pure oxygen high temperature and nitrogen barrier time delay, so that the micropores inherent in bamboo charcoal are refined and honeycomb, It is made by melt-spinning with polyester modified chips with a tendency of honeycomb microporous structure. This unique fiber structure design has the characteristics of moisture absorption and ventilation, bacteriostasis and antibacterial, warm in winter and cool in summer, and environmental protection.

Its solid wood charcoal, bamboo charcoal, etc. are mainly used to filter water, and secondly, it can be used to dry air. Filtering PM2.5 is really not his strong point. In theory, the charcoal fiber masks of the same thickness are not as protective as ordinary cotton masks.

4. Encyclopedia introduction of 3M masks: 3M is both the company's name and a registered trademark. The full name of 3M is Minnesota Mining Manufacturing Company. 3M is a global diversified technology company. 3M's anti-particulate mask products sold in China are from different origins, and all of them have obtained China Lao An (LA) certification in addition to the certification required for the origin. "3M masks" refer to all 3M products that can be called masks: such as warm masks, anti-particulate masks (dust-proof masks), medical protective masks and medical surgical masks.

In fact, 3M masks should be regarded as the mask standards introduced by 3M companies, so many domestic companies also produce masks that meet the specifications. According to the wearing method, there are a head-mounted type and an earband type (this is more suitable for our aesthetics, the head-mounted type is too eye-catching), etc. According to the protection level, it can be divided into 90 (protective force 90%), 95 (protective force 95% ), Etc., according to the protection can be divided into dust (we need most) and anti-smoke.

Disposable face mask supplier believes that: 3m standard masks are cheap (and cheaper than cotton masks) and have the best protection. But you ca n’t wash it (but you can wear it repeatedly until it becomes completely dirty, the protective power is still higher than that of ordinary cotton masks), the breathability is poor, and you ca n’t wear it for a long time.
