Material Characteristics
Everything has its two sides, disposable masks are the same, it has some disadvantages at the same time as the advantages:
Advantages
Advantages: ventilation is very good; able to filter the poisonous gases; able to keep warm; It can absorb water; it can be waterproof; it is stretchable; it is not fluffy; it feels very good and quite soft; it is lighter than other masks; it is very elastic, and it can be restored after stretching; the price is relatively low, and it is suitable for mass production;
Disadvantages
Disadvantages: Compared with other fabric masks, disposable masks can not be washed; they are not suitable for mass production because of their high quality and high quality. Disposable masks can not be cleaned; because the arrangement of its fibers are all in a certain direction, so it is also easier to be torn; compared with other textile fabric masks, disposable masks are less strong and durable than other masks.

Disposable medical masks have a single layer of
No.
Medical masks are generally three layers, respectively, the inner layer of skin-friendly materials, the middle layer of isolation filter layer, and the outer layer of special materials antibacterial layer. This can effectively play a protective role, isolation of dust, liquid, bacteria and so on.
Medical masks generally do not have a single layer, a single layer of mask protection may not reach the medical standard. But in daily life, dust or flu prevention, etc., may use a single-layer mask is also sufficient.
Disposable three-layer non-woven mask is a medical surgical mask
Disposable three-layer non-woven mask is a category of medical surgical mask.
Disposable three-layer non-woven masks, generally made of professional for medical and health care . Fiber nonwoven fabric inside two layers, the middle of the increase of a layer of filtering meltblown cloth by ultrasonic welding and become, the nose at the environmentally friendly all-plastic strips, does not contain metal. Disposable three-layer non-woven mask in daily life, as the prevention of respiratory transmitted diseases, influenza and other diseases is possible.
Medical surgical mask materials can also be non-woven materials to prevent dander, respiratory microorganisms spread to open surgical wounds, and to stop the spread of body fluids from surgical patients to medical staff, playing a two-way biological protection.
The role of the three layers of disposable masks
The structure and role of the three layers of disposable masks are as follows:
The first layer is a moisture-proof nonwoven fabric, which can block splashing liquids and droplets.
The second layer is meltblown filter fabric, which can block tiny particles with a diameter of 0.3-0.1pm, and can also block out about 99% of bacteria.
The innermost layer is the comfort layer, which is a long-fiber non-woven fabric that serves two main purposes, the first is to absorb the liquid produced by breathing, and the other is for wearing comfort.
Three layers of medical masks but very thin useful
If it is a regular medical mask is useful.
The mask is not the thicker the better protection, as long as the purchase of a regular medical mask, even if the touch is very thin, but also can play a protective role.
The thicker the mask, the more likely it is that the filtration is substandard. If the mask is too thick, it will also increase the breathing resistance, causing discomfort, not suitable for the elderly, children to wear.

What does it mean to be a medical non-sterile mask
Medical non-sterile masks are also a kind of medical masks, medical masks are generally divided into medical masks, medical surgical masks, medical masks, these three masks have a certain role of prevention and isolation of microbial infections, which are non-sterile masks. Sterile masks mainly refers to the microbial control standards, that is, allowing a certain amount of bacteria, but must be within the control range of the mask, is a certain protective role.
Can medical non-sterile masks be used
Can be used.
Many people say that medical non-sterile masks can not be used, but in fact, both medical non-sterile and medical sterile masks, both can be used, can effectively help people block as well as prevent microbial infection.
One of the biggest differences between medical non-sterile masks and medical sterile masks is the presence or absence of sterilization in the production process, non-sterile masks comply with microbial control standards, allowing a certain amount of bacteria, but must be within a controlled range; sterilization masks do not allow the presence of bacteria.
Can non-sterile masks protect against viruses
Since non-sterile masks are also divided into two types, medical non-sterile and medical sterile masks, non-sterile masks can be effective in protecting against viruses if they have a standard filtration efficiency for non-oily fine particulate matter, such as medical non-sterile masks.
The biggest difference between non-sterile masks and sterilized masks is the presence or absence of the final sterilization process of the finished product, and other indicators, such as filtration efficiency or airflow resistance and other indicators are the same requirements.
Generally non-sterile masks are also managed in strict accordance with the medical device management method, enough to meet the needs of people's daily life, but can not be used to strictly control the microbiological environment of the medical work, such as ICU, operating room and other places.
Difference between non-sterile and sterile masks
1, non-sterile masks are made in accordance with microbiological control standards, that is, a certain amount of bacteria are allowed, but within a certain controllable range; while the sterilized masks are sterilized, and in the validity of the package is sterile.
2, non-sterile masks are suitable for general haze days, dust and wind; and sterile masks are used in, for example, ICU, operating rooms and other medical places that require strict control of the microbiological environment.
3, non-sterile masks are generally not individually packaged; and sterilized medical masks are generally to ensure the sterility of the state, are independently packaged; but both non-sterile medical masks or sterilized medical masks have protective functions, can block droplets, to prevent cross-infection.
How long can a non-sterile medical mask take
A non-sterile medical mask is not recommended for long periods of time, and it is generally recommended that it be replaced every 2-4 hours. If you wear a disposable mask for too long, more than 4 hours, a large number of particles in the air will be adsorbed on the outside of the mask, blocking the gap in the mask's overdose material. Not only will the mask's efficiency decline, but also make the breathing resistance rise, a long time, on the human nasal mucosa has an impact, reducing the original physiological function of the nasal cavity.
Tips: If you encounter the following situations should be replaced in a timely manner, such as breathing difficulties, masks have broken or destroyed, masks and face can not be close to the face, masks are contaminated, have been used in isolation wards or patients in contact with, and have a strange odor.
