First look at the mask for coronavirus

Today, the epidemic has spread to more than 100 countries around the world, and masks will become the biggest hot product in 2020. In just two months, many logistics providers,factories, sellers,and platforms have transformed into mask sellers. Too many people have experienced this,the sellers of masks who claim to be in stock have delayed delivery after paying, delayed for various reasons,even worse,the sellers took the money and closed the business,you can never reach them again. The news reported that there were hundreds of mask fraud cases.

Demand exceeds supply, high-quality factories that meet certification and qualifications have basically been requisitioned by the government,giving priority to the supply of medical systems and severely affected areas (Wuhai,Hubei province). About mask for coronavirus,how many details do you know?

China is a big country in the mask industry, producing about 50% of the world's masks, before the epidemic,the maximum daily output of Chinese masks was more than 20 million. The fastest mask production speed is 120-200pcs per minute, but a standard process of analyzing and disinfecting takes 7 days to 15 days. Because the medical mask is sterilized with ethylene oxide, after the sterilization, there will be residual ethylene oxide on the mask,which not only stimulates the respiratory tract but also carcinogens. So the residual ethylene oxide must be released by analytical methods to meet the safety content standard. After passing the test, it can be put into the market.

The three major mask industry bases in China, Hubei Xiantao, Henan Zhengzhou, and Jiangsu Yangzhou. From the perspective of the industrial chain, manufacturers of upstream raw material,PP Non-woven fabrics, Meltblown fabrics, nose bridge strips, ear band materials, and mask production equipment and midstream mask manufacturing companies are mainly concentrated in the Yangtze River Delta region, and downstream distribution companies are too scattered.

Classification of mask

1.Classified by scope

  1.1 Medical mask: medical ordinary masks, medical surgical masks and medical protective masks.

1.2 Particulate matter protective mask: industrial use meets GB2626-2019 standard, special labor protection products safety mark (LA certification), if used for anti-fog and haze need to use insert type, with GB/T32610-2016 standard.

1.3 Thermal mask: suitable for winter wear, just need to meet the relevant standards of fabrics.

1.4 Other special industries mask: such as chemical industry,etc.

2. Classified by material

2.1 Gauze mask: Gauze mask is still used in some workshops. the requirements of GB19084-2003 standard is low, and they can only protect large particles of dust.

2.2 Non-woven mask: Most disposable protective masks are Non-woven masks, which are mainly based on physical filtration and electrostatic adsorption.

2.3 Cloth mask: Cloth mask only have a warming effect and have no effect of filtering small particles.

2.4 Paper mask: Suitable for food, beauty, and other industries, with good air permeability, easy to use and comfortable, the paper used follows GB/T22927-2008 standard.

2.5 Mask made of other materials, such as new material for bio-protection filtering.

3. Classification by wearing method

3.1 Head-mounted: Suitable for workers who wear for a long time in the workshop.
3.2 On-ear style: Easy to wear, suitable for frequent wearing.
3.3 Neck-wearing type: S-hook, some soft material connectors, connecting ear bands are converted into a neckband type, suitable for long-term wearing, more convenient for workers such as wearing hard hats or protective clothing in the workshop.

4. Classification by shape

Mask is divided into three types: flat, foldable, and cup-shaped. The flat mask is easy to carry, but have poor adhesion; folding mask is easy to carry,cup-shaped breathing space is large, but not convenient to carry.

5. Classification by protection level

Different countries and industries have different standards, which are divided into different protection levels according to different particle filtration efficiency.

Chinese standards of mask

GB2626-2019 This standard filter element is divided into two categories (KN and KP) according to the filtering performance. This type of mask can block the virus for a short time, but it cannot be used to contact patients who may have splatter or contact the patient for a long time.

GB / T32610-2016 technical specifications for daily protective mask, which are standards for the civilian mask.

YY / T0969-2013 This standard is an industry-standard for disposable medical masks. Ordinary medical masks meet this standard.

YY0469-2011 medical surgical mask is the industry standard for medical surgical masks. It is suitable for disposable masks worn by clinical medical staff during invasive operations and other procedures.

GB19083-2010 medical protective mask, this standard applies to medical work environment, filtering particulate matter in the air, blocking droplets, blood, body fluids, secretions, etc.
