Civil sanitary masks are used to filter the air entering the nose and mouth. Civil sanitary masks prevent harmful gases, odors and water droplets from entering and leaving the wearer's nose and nose. Civil hygiene masks are mainly divided into cotton masks, non-woven masks, polymer masks, activated carbon powder filter masks, and activated carbon fiber felt masks.
The N95 mask is one of nine particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). The N95 mask is not a specific product name. As long as it meets the N95 standard and passes the NIOSH review, it can be called a N95 mask. The N95 mask can be used for particles with an aerodynamic diameter of 0.24 ± 0.6 μm (physical diameter 0.075 μm ± 0.020 μm). The filtration efficiency reaches over 95%.
Medical masks are mostly made of one or more layers of non-woven fabrics. The main production process of medical masks includes meltblown, spunbond, hot air or acupuncture, etc., which is equivalent to resisting liquids, filtering particulates and bacteria, and is a medical protective textile. Medical masks consist of a mask and a tightening strap. Medical masks are divided into inner layer, middle layer and outer layer. The inner layer is ordinary sanitary gauze or non-woven fabric. Non-woven fabric or ultra-thin polypropylene meltblown material layer.
There are many classification methods of activated carbon masks. Generally, we divide them into two categories according to their structure and working principle: air-filtered activated carbon masks and air-supply activated carbon masks.
Non-woven mask A non-woven mask is made of cotton degreased gauze or knitted fabric, and various non-woven fabrics are sandwiched between woven masks. Another type of non-woven mask is directly made of non-woven fabric. Non-woven masks have a good filtering effect and a little poor ventilation.
