According to relevant data, in the past month or so, the amount of information about “masks” on the Internet has exceeded tens of millions, and netizens are highly concerned about the “protective effect” and “number of uses” of “masks”.
In addition, people are also very concerned about the raw materials of masks, among which ptfe medical mask filter material is one of the materials used to make masks.
Melt-blown nonwovens are one of the one-step polymer fabric-making technologies.
After the polymer resin is extruded, melted and plasticized through a screw extruder, it is accurately metered to a special melt distribution chamber through a metering pump, and then enters the spinning melt pool after rectification. The holes are ejected into filaments, which are drawn into ultra-fine fibers under the action of high-speed and high-pressure hot air flow.
The drawn ultrafine fibers spread with the volume expansion of the jet airflow. Under the guidance of the suction wind, they are evenly spread on the collection device and stick to each other using their own waste heat to form melt-blown non-woven fabrics. Woven cloth.
The ptfe medical mask filter material made by mechanically stretching ptfe material can ensure complete retention of impurities such as bacteria and has a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
It is a ptfe medical mask filter material manufacturer that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
