The difference between ordinary medical masks and surgical masks
is mainly from material and protection.
The material of ordinary medical surgical masks
is generally two layers, or three layers, the most important core layer is the structure of the melting cloth. Ordinary medical mask melting is relatively thin, and the surgical mask
is thicker, so that it is stronger than the adsorption. From the perspective of the tension, the regular hospital mask is selected is a fixed method of the elastic band, and the surgical mask selection is a bundled lacing method, which makes the mask and facial stickers, compared to ordinary medical masks. The fixation method of the elastic band is much stronger, so the surgical mask
is most suitable for the prevention of new crown viruses.
