[Abstract]:
Medical masks belong to the second category of medical devices. The food and drug regulatory authorities of all provinces, autonomous regions, and municipalities directly under the Central Government shall, in accordance with the requirements of the "Notice on Strengthening the Supervision of Medical Masks" (Food and Drug Administration Office [2009] No. 95), strengthen the supervision of the approved medical masks in their jurisdictions. , Strictly require relevant companies to organize production and standardize instructions and packaging labels in accordance with national standards, industry standards or registered product standards, and guide medical institutions and the public to choose appropriate masks according to the purpose of use.

Medical masks belong to the second category of medical devices. The food and drug regulatory authorities of all provinces, autonomous regions, and municipalities directly under the Central Government shall, in accordance with the requirements of the "Notice on Strengthening the Supervision of Medical Masks" (Food and Drug Administration Office [2009] No. 95), strengthen the supervision of the approved medical masks in their jurisdictions. , Strictly require relevant companies to organize production and standardize instructions and packaging labels in accordance with national standards, industry standards or registered product standards, and guide medical institutions and the public to choose appropriate masks according to the purpose of use. Medical masks are divided into ordinary medical masks, surgical masks and medical protective masks, and their protection levels are gradually increased.

Filter material

1. Disposable medical surgical masks, ordinary medical masks

Meet the relevant registered product standards (YZB), generally lack the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks. Ordinary medical masks are generally ear-mounted, which can be used for one-time hygiene care in ordinary environments, or for blocking or protecting particles other than pathogenic microorganisms such as pollen.

2. Surgical mask

is divided into 3 layers, the outer layer has a water blocking effect to prevent droplets from entering the mask, the middle layer has a filtering effect, and the inner layer has a moisture absorption effect. Medical surgical masks are generally lace-up type, which are suitable for basic protection of medical staff or related personnel, as well as protection to prevent the spread of blood, body fluids and splashes during invasive operations. Comply with YY 0469-2004 "Technical Requirements for Medical Surgical Masks" standard, important technical indicators include filtration efficiency, bacterial filtration efficiency and respiratory resistance:

1) Bacterial filtration efficiency: Under specified conditions, the filtration efficiency of Staphylococcus aureus aerosol with an average particle diameter of (3±0.3) μm is not less than 95%;

2) Respiratory resistance: Under the condition of filtration efficiency and flow rate, the inhalation resistance does not exceed 49Pa and the exhalation resistance does not exceed 29.4Pa.

3. Medical protective mask

is suitable for the protection of airborne respiratory infectious diseases, and has a very good blocking effect on dust and haze. The protection level is the highest among these types of masks. The N95 masks produced by Juneng Nonwovens Factory fall into this category. Comply with GB19083-2003 "Technical Requirements for Medical Protective Masks" standard, important technical indicators include non-oily particle filtration efficiency and airflow resistance:

1) Filtration efficiency: Under the condition of air flow (85±2)L/min, the filtration efficiency of sodium chloride aerosol with aerodynamic median diameter (0.24±0.06)μm is not less than 95%, which is in line with N95( Or FFP2) and above.

2) Inhalation resistance: Under the above flow conditions, the inhalation resistance does not exceed 343.2Pa (35mmH2O).

Non-woven masks used in hospitals can also be described as medical masks. In every hospital we often go to, we will see that every nurse and doctor will wear their own mask.

Sichuan Juneng Filter Material Co., Ltd. is a PP non-woven fabric manufacturer. The main filter materials for mask cloth include BEF series, P KN series, and N series PM2.5 series. The technical indicators have been tested and certified by SGS, CE, American Nielsen, and STOS. ; Also passed the ISO9001: 2008 standard certification. It is breathable; high efficiency; low resistance; uniform fiber distribution; non-toxic and no peculiar smell. In addition, our company also produces oil (liquid) cotton, oil (liquid) pads, oil/liquid (sticks, cords, suits); wipes; provides printing processing, finished masks, etc., with a large supply capacity.
