Nanotechnology Used in Iran for Production of Moisture-Permeable Insulation
“The moisture-permeable insulation has been designed for precise coating with advanced features and high flexibility for scientific and industrial applications,” Farshid Chini, the managing director of the knowledge-based company and associate professor at the University of Tehran, told ANA.
“Nanotechnology is used in the production of this product, and the presence of nano crystals in these insulations provides greater strength,” he added.
“This cement-based moisture-permeable insulation penetrates up to three centimeters into cement and concrete, and we use this insulation after the cement or concrete is used in the desired location, and it prevents water from entering and also strengthens the cement and concrete,” Chini said.
Noting that in many cases, in areas where cement-based insulation is used, the insulation is damaged by moisture penetration, and sometimes access to the desired location is difficult, he said, “Therefore, our company has developed this technology and produced insulation that is not likely to be penetrated by moisture.”
In a relevant development last year, an Iranian nanotechnology firm had also produced a special thermal insulation which has applications in different industries and buildings.
“This product is a thermal insulation coating that replaces traditional products. The use of nanomaterials improves the performance of the thermal insulation so that the heat transfer coefficient decreases in this product and the specific heat of the coating increases,” said Narges Saffarian, the chairwoman of the board of directors of ‘Pousheshhay-e Mohafez Payeh Aab Pavan’ group.
“This coating is used in much smaller thicknesses than glass wool and stone wool which is of great importance in building facilities. The durability of this insulation is high and it does not have the corrosion common in industrial coatings. The insulation itself adheres to the surface and is highly durable due to the elimination of condensation,” she added.
“The product is proper for reducing the temperature of the external surfaces of industrial equipment, including tanks and reactors, and it also reduces fuel and energy consumption in equipment with high temperature and thermal energy, specially in petrochemicals, refineries and metal industries,” Saffarian said.
