What Should Surgical Mask Making Machine Manufacturers Pay Attention to in Controlling the Quality and Safety of Masks?

How to control the quality and safety of masks?

  1. In view of the difficulty in controlling the quality of disposable mask filter materials through convenient and effective inspection methods, the standardized operation of the production quality management system is the main way for surgical mask making machinemanufacturers to ensure the quality of mask products. Therefore, they will be reviewed in the registration technology review and system evaluation. Inspectors will pay attention to the production process and supply sources of disposable mask filter materials. Surgical mask making machine manufacturersshould control the filter materials of disposable masks, clarify the source and quality requirements of the filter materials, and have a relatively stable production process and supply sources to ensure product quality. It is recommended to use some reliable testing equipment for inbound inspection. Raw materials: sampling inspection of raw non-woven fabrics is required.

  1. The safety and effectiveness of masks are only some factors that play a protective role. The correct use and wearing of masks will also directly affect the protective effect. Therefore, surgical face mask machine manufacturerneeds to clearly state all the information required by the user in the instruction manual to avoid misuse of the mask and reduce the risk of cross-infection. For example, indicate the wearing method, clearly identify the front and back of the mask, recommend usage time, indicate the level of filter material or related instructions.

  1. It should be noted that sterile medical masks are produced under the conditions of class 100,000 clean factory buildings. Its characteristic is that the maximum allowable number of dust particles is equal to or greater than 0.5 microns, and the number of particles must not exceed 35,000, and the number of particles greater than or equal to 5 microns must not exceed 20,000. In addition, the maximum allowable number of microorganisms and the number of planktonic bacteria should not exceed 500 per cubic meter; the number of bacteria deposited in each petri dish should not exceed 10. At the same time, the pressure difference between clean rooms of the same cleanliness level is the same. For different cleanliness, the pressure difference between adjacent clean rooms is greater than or equal to 5Pa, and the pressure difference between the clean room and the non-clean room is greater than or equal to 10Pa. This is mainly to ensure that the air flows from the clean area to the unclean area, and to avoid the air flow back. The temperature in winter is usually controlled at 20-22°C; the temperature in summer is controlled at 24-26°C; the fluctuation is within ±2°C. The humidity of the clean room in winter is controlled at 30-50%, and the humidity of the clean room in summer is controlled at 50-70%. When there are no special requirements for temperature and humidity, it is recommended to wear clean work clothes without feeling uncomfortable.
