In the new epidemic of pneumonia, medical masks used for defense have turn out to be a single of the most well-known products. The huge market desire has spawned the prosperity of the health care mask manufacturing market. Several businesses have switched to march into masks, but the mask industry prosperity hides hidden quality considerations.
What is the distinction in between medical masks and civilian masks? How do learn more here recognize real and phony medical masks? Is it reputable to recognize medical masks by indicates of burning, water immersion, tearing, etc.? Nano masks are also freshly introduced on the marketplace, how secure are they?
To this finish, the initial financial reporter interviewed Cao Mengjie, an expert of the national health-related cleanliness materials and dressing expert health care device standardization technologies unit, and the head of the domestic product division and item advancement middle of Ogilvy Health care Merchandise Co., Ltd.
Ogilvy Health care is a entire world-renowned producer of healthcare dressings and a important company in Hubei province for avoiding and controlling items to ensure production and source. In other perform, he has participated in 3 provincial and municipal scientific analysis assignments, applied for a lot more than fifteen national patents, and participated in the review and revision of several healthcare gadget expectations.
Civil masks can not achieve the powerful bacterial filtration effectiveness index
1st Fiscal: What is the big difference among health care masks and civilian masks?
Cao Mengjie: Common civilian masks are largely utilised for residents' day-to-day chilly defense, dust blocking, privateness safety, and style matching. There is no requirement for bacterial barrier efficiency, and typically it does not fulfill the successful bacterial filtration performance index. Paper, regular non-woven fabric, polyurethane foam, and so on. Health care masks are an infection security goods for health-related personnel to use in distinct infection threat ranges. They belong to the next group of healthcare units. The related product standards are bacterial filtration, particle filtration, adhesion (health-related protecting masks), air flow resistance, blood There are clear and rigorous requirements on indicators these kinds of as penetration and surface moisture resistance.
Ordinary civilian masks have not been unveiled but. Industrial dust masks (GB 2626-2019 "Respiratory Safety-Self-Suction Filter Anti-Particle Respirator") are primarily ideal for the defense of staff in particular positions this sort of as mines and dust environments, though There are a lot of income on the market place during the recent epidemic, but the everyday basic isolation wears large air flow resistance, bad comfort, and is not easy to wear for a extended time daily protective masks (GB / T 32610-2016 "Daily protecting mask technological technical specs") are largely employed for daily Protective masks worn to filter out particulate subject in an air-polluted atmosphere in lifestyle have higher respiratory resistance and are not appropriate for young children to dress in.
Healthcare masks are specifically divided into disposable health-related masks, health care surgical masks, and health care protecting masks. The specifications carried out are YY / T 0969-2013 "Technological Needs for Disposable Health care Masks", YY 0469-2011 "Complex Specifications for Medical Surgical Masks" , GB 19083-2010 "Technical Requirements for Medical Protective Masks", in which the 1st two specifications are industry standards, the latter is a national mandatory regular.
Different grades of medical masks have various main indicators. Between them, the main indicators of disposable healthcare masks are bacterial filtration performance ≥95%, pressure big difference ≤49P, and earband energy ≥10N the main index of medical surgical masks is bacterial filtration effectiveness ≥95%, particle filtration effectiveness ≥30%, stress variation ≤49Pa, ear strap strength ≥10N, avoid blood penetration, and so forth. The core index of healthcare protective masks is particle filtration performance ≥95%, adhesion issue greater than 100, airflow resistance ≤343.2Pa, floor moisture resistance ≥3, earband toughness ≥10N, avoid blood penetration, and many others.
1st Fiscal: Health-related masks are known to have rigid production problems, in which are they primarily reflected?
Cao Mengjie: The manufacturing of healthcare masks calls for a medical system registration certification authorized by the provincial drug regulatory agency. At the exact same time, the production business should also have a healthcare device (mask) manufacturing license ahead of it can be produced. The everyday supervision is largely regulated by the drug regulatory agency. There are rigid declaration, approval and supervision regulations, and regular civilian masks belong to common commodity administration.
The Foodstuff and Drug Administration (2016) No. 37 doc issued by the State Drug Administration (previously the Condition Food and Drug Administration) in 2016 clearly needs the generation atmosphere of medical protecting masks to be 100,000 cleanse workshops, and according to health-related units Appropriate restrictions of production, medical surgical masks and disposable health care masks are usually essential in clear workshops with a level of not much less than three hundred,000, and civil masks have no needs for production environments.
Medical masks all have index demands for microorganisms, and the needs for aseptic grade items are aseptic, and the residual ethylene oxide is not more than 10ug / g ordinary civilian masks do not need microbiological indicators, and a couple of top quality-aware civilian mask manufacturers will use GB 15979-2002 "Sanitary Standards for Disposable Cleanliness Items" to handle microbiological indicators.
Burning masks cannot be 100% real or untrue
Very first Monetary: Is it trustworthy to discover fake masks, on the internet transmission this kind of as burning, immersion, and tearing? How do ordinary people distinguish faux masks?
Cao Mengjie: First of all, the method of burning, immersing and tearing through the web cannot distinguish 100% of the faux masks. The combustion technique can in fact be used to recognize numerous kinds of resources. The soften-blown non-woven cloth is produced of polypropylene. The flamable material is a false mask of the filter layer, but the filter layer of most fake masks is also incombustible and cannot be genuinely identified, nor can 100% of the phony masks be excluded by immersion in h2o.
At current, there are no obligatory common demands for common civilian masks, so there are several item variations and uneven top quality. It is suggested that regular folks acquire medical surgical masks or use disposable medical masks for every day wear security. Safety safety is confirmed. Want to distinguish the correct and fake of the health care mask mainly has the subsequent measures:
Consider a search at the item packaging, regardless of whether there is a distinct "Health care protecting mask", "Medical surgical mask", "Disposable healthcare mask" and other health-related masks on the package deal. In accordance to the specifications of the health care device regulations on packaging information, normal health care mask packaging will have data this sort of as creation license variety, merchandise registration quantity, specialized requirement amount, merchandise guide and so on.
Next, search at the construction of the merchandise, cut the mask, see if the three-layer structure is offered, and whether or not the thickness is the very same as the standard health-related masks on the industry specially whether the white soften-blown non-woven material in the middle is offered, and the soften-blown non-woven material is really thin The long fiber non-woven material is not large in strength, effortless to tear, and has a brittle sound when torn. In addition, appear at a small piece of soften-blown non-woven fabric in opposition to the light, you can see the fiber texture, if the fiber thickness is extremely uneven, it signifies that the good quality of the soften-blown fabric is inadequate, lower out a piece of melt-blown non-woven material, and carefully Shut to the soften-blown non-woven material, the soften-blown non-woven cloth will are likely to appeal to to the fingers.
3. Drop h2o to the outer surface of the health-related protective mask to see if it is a small h2o drop. If it does not infiltrate into the cloth for 5 seconds, you can effortlessly figure out the drinking water repellency of the mask floor.
4. To see if the welding points of the ear straps are company, pull the ear straps by hand. If the ear straps are not welded securely, they may crack.
The safety of nanofiber masks continues to be to be observed
1st Fiscal: Some makers on the market have launched nano masks, which declare to be used frequently. Is it dependable? Is this type of mask mature in generation engineering?
Cao Mengjie: From the specifications of filtration overall performance and antibacterial performance standards, the current very good good quality meltblown fabric is a more economical and appropriate filter material. The fiber diameter of meltblown nonwoven material can be reduced by strengthening the meltblown tools and procedure (now one -5um), so that the melt-blown fabric has considerably less air flow resistance beneath the premise of enhancing the filtering capability, creating it more cozy to wear. For the nano masks that seem on the market, because there are handful of documented complex contents, is their basic safety reputable? Is the economic system feasible or appropriate for commercialization? To be additional noticed.
