As we all know, the main function of ordinary fabric masks is to keep warm and has little significance in inhibiting the spread of viruses. However, medical surgical masks, as a type of disposable mask, can play an effective protective role, mainly due to PTFE single-component clothing film inside the mask.
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.
PTFE one-component clothing membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, there are up to hundreds of millions of micropores per square centimeter, and the filtration level can reach H13 -U16, can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
Washing with water or backflushing can restore performance and greatly extend service life.
The ptfe single-component clothing film produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of ptfe film; Production and testing instruments imported from the United States are used to test the quality of the PTFE film, and it has passed international SGS testing and certification, as well as ISI testing and certification.
