The disposable mask filter membrane is used as the protective layer. The fiber diameter is only tens of nanometers (90 nanometers for the new coronavirus). It directly uses the principle of physical isolation to filter viruses with hard core. The filtration efficiency reaches more than 99%, and the filtration performance is excellent. It makes us feel more at ease.
Both medical surgical masks and medical protective masks have performance requirements in terms of waterproofness and particle filtration efficiency, while disposable medical masks have no requirements, so their waterproofness is poor.
In addition, the waterproof performance of medical surgical masks is higher than that of medical protective masks, and the particle filtration efficiency of medical protective masks is higher than that of medical surgical masks.
The dust removal efficiency of the disposable mask filter membrane can reach more than 99.9995%.
The minimum pore size of the film can reach 0.1um, which can capture most solid particles and liquid droplets. Since the pore size of the mask film is much larger than water vapor molecules, and polytetrafluoroethylene is a hydrophobic material, water droplets cannot penetrate the micropores, so Has good moisture permeability, breathability and waterproof properties.
The melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃.
The disposable mask filter membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency, for some extremely fine particles with a diameter of 0.1um-0.3um , the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
