The polytetrafluoroethylene microporous membrane prepared from polytetrafluoroethylene as raw material is a membrane material with excellent performance for filtering and separating microparticles. Let us take a closer look below.
A typical medical nano antibacterial mask also consists of an outer layer, a middle layer, an inner layer, ear hooks, a nose clip and other parts.
The special thing about nano masks is that the middle layer is made of nano membrane with smaller pore size (100-200 nanometers), which is generally made of PTFE material.
There are already companies using them, and masks made of nano-fluorine materials are on the export list to the United States.
When traveling across the ocean, the filtration efficiency will not be lost because it does not rely on static electricity.
PTFE microporous membrane has a three-dimensional network structure with no through holes.
The porosity and pore size distribution are important indicators to measure the membrane.
The porosity of Teflon microporous membrane is generally between 80% and 95%.
High porosity will increase ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
Usually, membrane thickness is not an indicator for membrane evaluation. If the membrane thickness is too thick, it will easily cause problems such as low air permeability and high operating pressure.
