Scientists in Iran Apply Electrospin Nanofibers on Filter Papers
Specialists at ‘Fanavaran Nano Meqyas’ company applied a thin layer of electrospun nanofibrous polymeric web which can be produced in the form of a nanoporous filter. It results in production of a superior filtration capacity, lowest pressure drop in the passing air/liquid flow and long lifespan.
Covering the surface of conventional air filters with a thin layer of the nanofibers improves filter efficiency and increases dust absorption capacity.
The product can be used in making respiratory face masks, air filter papers, and separation of compounds from liquids.
Earlier this year, an Iranian knowledge-based company had also used nanofibers to make filters for industrial units, especially power plants, last longer.
Nanofiber filters possess a handful of advantages over conventional fibers.
Nanofiber filters tend to have very high filtration efficiency. They require less energy for the air to ventilate through them.
Moreover, they are cost-efficient as they last longer and do not need higher-powered ventilation systems for circulating air.
The industrial and power plant filters produced in an Iranian knowledge-based company have features such as better protection of turbine parts, reduction of downtime costs, an increase of power generation capacity, and an increase of filter life to at least 1.5 times.
The company has been exporting the filters to Iraq and Afghanistan over the past two years.
