Porosity of disposable mask filter material
Although it is only April, if we were to judge the best-selling product in 2020, it would be “face masks”.
Recently, with the outbreak of the new coronavirus pneumonia around the world, masks, which were once inconspicuous, have become the most scarce supplies in various countries.
The disposable mask filter material is the core material for making masks.
In China, mask prevention and control began with the Harbin plague.
In 1910, Dr. Wu Liande, then deputy supervisor of Beiyang Army Medical College, invented the “Wu-style mask”.
For this kind of mask, cut surgical gauze into 3 feet long, fold each strip into double layers, place a piece of cotton in the middle, and then cut each end of the gauze into two strips to form a two-layered gauze bandage.
When using it, cover your mouth and nose with cotton in the middle, and tie the upper and lower tails at both ends behind the head.
Disposable mask filter material is a polymer waterproof material.
From a production point of view, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
PTFE film manufacturer specializes in the production of disposable mask filter materials. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite cutting workshop to ensure the production quality of PTFE membrane; the product materials produced They all use imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.99995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
