Iranian Nanotechnology Firm Produces Polymeric Manhole Cover
‘Tose’eh Honar Matin’ company has produced the removable plate which acts as a lid to cover the opening of a manhole to prevent anyone or anything from falling in or to keep out unauthorized people and materials.
The plate is a nanoparticle-reinforced polymer composite which is low-cost with high mechanical properties.
The addition of amorphous nanoparticles as nanofiller to the polymer matrix of the manhole cover has resulted in higher resistance to chemicals and corrosion, improved mechanical properties, e.g. the strength, module, and toughness, and enhanced density.
Earlier this year, an Iranian nanotechnology company had also succeeded in manufacturing unplasticized polyvinyl chloride (UPVC) profile for building doors and windows.
‘Shahin Sazeh Fajr’ company’s product has been modified by certain nanoparticles. Such an improvement has dedicated a broad spectrum of significant features to the UPVC matrix such as satisfactory impact strength, high fracture toughness, and favorable stiffness.
The impact resistance and compressive strength of UPVC parts have been enhanced through the incorporation of certain nanoparticles up to 3 and 12 times higher than that of standardized counterparts, respectively.
The product can be used as a building material, specially double-glazed door, frame and window profiles, an insulator in cabling, dentistry and piping industry.
