The COVID-19 epidemic is approaching fiercely. As a combat tool during the epidemic prevention period and the resumption of work, masks are not all masks that can provide good protection. Only medical surgical masks and KN95 series masks can play a good protective role. Let’s talk about the disposable medical mask filter material.
The application time of KN95 masks varies depending on the environment. For example, in the case of direct contact with bacteria and viruses, it is generally used continuously for 6 to 8 hours, but not more than 8 hours.
If used for general protection, the mask should be discarded when it comes into contact with blood or droplets. If the mask is damaged, it should be discarded. When the breathing resistance increases, it should be discarded.
If the above situation does not exist, it is generally recommended to use two per week, and at most, use one for five working days.
The disposable medical mask filter material used in masks is a microporous film formed by expanding and stretching polytetrafluoroethylene (PTFE, commonly known as “Teflon”) resin, with an average pore size reaching the nanometer level. .
It can be observed under a scanning electron microscope that the micropores of this polytetrafluoroethylene nanofiltration membrane are evenly distributed, the pore diameter is about 100 times smaller than melt-blown cloth, and the porosity is as high as more than 80%.
It is a high-tech enterprise specializing in the research and development, production and sales of disposable medical mask filter materials. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we The products produced are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
