The number of confirmed cases of COVID-19 worldwide has exceeded 10 million, and epidemic prevention and control has become normalized. Masks have become a necessity in our lives. kn95 masks are the first choice. Its main component is the kn95 mask filter membrane. The company is committed to this material It’s all too familiar, so let me introduce it to you.
KN95 and N95 have many similarities in assessment indicators, such as filtration efficiency, breathing resistance, exhalation valve air tightness, field of view, headband, component requirements, information provided by the manufacturer, packaging, etc.
The assessment indicators of KN95 include leakage, dead space, air tightness, flammability, cleaning and disinfection, etc.
The kn95 mask filter membrane adopts a special processing technology and is a microporous film made by calendering, extrusion, and biaxial stretching.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
PTFE film manufacturer specializes in the production of kn95 mask filter membranes. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all Using imported raw materials, it has high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
