Will the mask smell
Will the mask smell? In our present situation, in fact, many people wear the mask all day. At first, we were not used to wearing the mask and felt breathless, but now we are getting used to it. Do you know that the mask will smell? Will the mask smell? 1
There are many reasons why the mask smells. First of all, we should look at it in different types of masks. Among them, the common reasons for the odor in non-woven mask are the odor produced by the raw material copy in the refining process; Bad merchants add back materials to reduce costs, resulting in mask odor; The sour taste caused by the wrong process in the production of non-woven activated carbon mask.
The cotton masks that are popular in the market in winter also have peculiar smell, which is mainly caused by the mildew and deterioration of cotton masks during storage and the residual smell of printed masks during printing. Some of these smells are harmless to the human body, of course, there will be differences according to the sensitivity of individuals to smells.
The reason why the disposable mask smells
The newly bought medical mask smells, which may be the residual smell after ethylene oxide disinfection and sterilization. It is recommended to take it out and ventilate it to eliminate the odor before wearing it.
If it is not a medical mask but an ordinary disposable mask, there are many reasons for the odor in the mask. Among them, the common reason for the odor in non-woven mask is the odor generated during the refining of raw materials; Bad merchants add back materials to reduce costs, resulting in mask odor; The sour taste caused by the wrong process in the production process of non-woven activated carbon mask.
Can disposable masks still be used?
If the masks are out of date or fake masks, they can be used. The main function of disposable medical protective masks is to isolate droplets or blood in the air, as well as body fluids or other secretions in the air, and to absorb dust, which is a very good tool to protect the health of doctors.
Generally speaking, disposable medical masks have to undergo rigorous testing and undergo certain medical treatment and maintenance before they can be used.
Precautions for wearing a mask
1. The wearing time should be appropriate: the medical protective mask can be used for 6-8 hours continuously, and it should be replaced in time in the following situations: the respiratory impedance is obviously increased (when breathing is difficult) when the mask is damaged or polluted; Mask and face can't close; After contact with a patient or a carrier of germs.
2. Carry out the tightness test after wearing: Face tightness test should be carried out when wearing the disposable medical mask. The simple test method is to wear a disposable medical mask and exhale forcibly, so that the air cannot leak from the edge of the mask.
Does the disposable mask taste normal?
3. Don't squeeze the mask with your hands: all kinds of masks can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, it will make the virus soak through the mask with droplets, which will increase the chance of infection. Does the mask smell? 2
Disposable masks smell
If you wear a mask, there are two reasons for smelling it. The first is that the mask is left behind during production, and the other is that our bodies breathe it out. So which one is it? If it is the odor of the mask, will it affect your health if you smoke too much?
There are a lot of bacteria in our mouth. When we are not clean, it will lead to the proliferation of bacteria, and when it reaches a certain level, it will cause odor. At this time, people who breathe through their mouths will smell the odor. If it is your own problem, you should treat it in time to avoid diseases.
Reasons for the odor of disposable masks
At present, all the masks popular on the market are disposable. Because of the great demand, they can only be produced in the simplest and fastest way. Generally, masks are directly paved with non-woven fabrics spun from polypropylene. Polypropylene is polymerized from propylene, which is non-toxic and odorless. However, various additives will be added in the production process, so it will produce odor.
many people want to know if inhaling this odor for a long time will affect their health. Don't worry, it won't be anything. Now you know that many people wear it 24 hours a day. Research shows that polypropylene contains chlorinated drinking water, tea and other substances, which are common substances in our lives and are not harmed, so please rest assured that odor has no effect.
In the control of the epidemic for several months, it has been very well reduced. Wuhan has been unblocked, but the epidemic prevention measures have not been relaxed. We must be cautious to keep the epidemic away, so we should cooperate with each other to wear masks, and don't let the temporary relaxation drag others down. Does the mask smell? 3
What is the mask
1. Facial tightness is better. The air leaked from the mask with a gap is directly inhaled from the gap without passing through the filter material, which seriously reduces the protective effect. Leaks can also cause glasses or goggles to fog. Preferably, the leakage rate is less than 1.5%.
2. The filtration efficiency of the filter material should be high. KN9, KN95 and KN1, the higher the filtration efficiency, the higher the interception rate of particulate matter and the lower the penetration rate of particulate matter. Gauze masks, common medical masks and medical surgical masks all have low requirements on particle filtration efficiency. Preferably KN95/KN1/KP1.
3. The protective effect should be high. The protective effect is the ability of the mask to block particles, which is a comprehensive embodiment of leakage and filtration efficiency. D, C, B, A, preferably Grade A, greater than 9%.
4. The inspiratory resistance should be low. The higher the inspiratory resistance, the more difficult it is to inhale, and the mask will have to be taken off after wearing for a while, which can not continue to protect. Preferably, the inspiratory resistance of KN95 mask is less than 5 Pa.
5. The expiratory resistance should be low. The greater the expiratory resistance, the more uncomfortable you feel, and you can't wear it for a long time. It is best that the expiratory resistance of KN95 mask is less than 5 Pa.
6. The air tightness of the exhalation valve is better. If there is an exhalation valve, it is better that the time for the air tightness of the exhalation valve to recover from -118 Pa to normal pressure is more than 5 seconds. The exhalation valve is not airtight enough to effectively isolate external particles, especially toxic gases.
7. The dead cavity rate should be low. Dead space rate refers to the proportion of carbon dioxide re-inhaled from the previous exhalation. The lower the ratio, the less carbon dioxide inhaled from the previous exhalation, the fresher the inhaled air and the higher the inhaled oxygen content, preferably less than .1%.
8. The headband, connector and exhalation valve cover are subject to greater tension. Wearing it will be strong and the connection will be tight, preferably more than 1 cattle.
9. In addition, the mask does not discolor, has no peculiar smell, has low formaldehyde content, neutral PH value, and has no carcinogenic dyes.
1. The mask must have a test report from a third-party professional organization. If the seller does not have a test report or does not show the test data, it is not credible.
The development technology of masks is changing with each passing day, and the protective performance index of traditional masks has fallen behind. You can look at the new mask of Mushengtang with more than a dozen patents.
