Sound-Proof Masterbatch for Wastewater Pipes Produced by Iranian Scientists
‘Parsa Polymer Sharif’ company produced the sound-proof polymer-based masterbatch in which inorganic nanoparticles are included to make the parts fabricated thereof sound-proof.
While used for the fabrication of pipes and fittings of the wastewater system, it can efficiently absorb the disturbing surrounding noises.
The addition of well-dispersed inorganic nanoparticles to the polymeric matrix in different concentrations has led to improved elastic modulus, impact resistance, and yield strength and increased toughness and stiffness of base polymer.
In a relevant development in June, an Iranian nanotechnology firm had also succeeded in making a soundproof pipe by using nanoparticles with application in construction industry.
‘Hamid Group’ is the company which produced the silent pipe which is comprised of three layers, with the middle layer made of a nanocomposite material.
There are both nanoparticles and microparticles present in this layer enabling desirable mechanical properties and optimized acoustic properties.
The use of nanoparticles in the polymer matrix in the intermediate layer has led to higher hardness and stiffness and enhanced acoustic properties.
The special sewage pipes can be used in insulation of fittings and construction projects.
