A domestic company has produced a nano-based thermal insulation that can be installed in residential and industrial units.
The environmentally friendly technological product contains nanostructured materials that prevent the wastage of energy and reduces the overall cost.
PAVAN Protective Coating Group (also known as PAMPA) has produced the thermal insulation in cooperation with the Iran Nanotechnology Innovation Council, the news portal of the Vice-Presidency for Science and Technology reported.
Coating the metal surfaces of roofs and gables to prevent the transfer of heat inside the building, reducing the temperature of external surfaces of industrial equipment such as tanks and reactors, as well as decreasing fuel and energy consumption in equipment with high temperature, especially in petrochemical, refineries and metal industries are the main advantages of the domestic heat insulation product.
The nano-based coatings lead to a drop in temperature and help conserve energy by using a thermal energy reflection mechanism designed at the molecular and macroscopic levels.
Since air is trapped at the molecular level, a nano-based insulation and coating can have a significant effect on the insulation’s efficiency. In fact, the use of nanomaterials improves the thermal insulation properties of this coating. They also do not produce smoke or chemical pollutants when exposed to heat.
Flexibility, water repellency and easy use are other features of this nanotech product.
Established in the fiscal 2015-16, PAMPA is focused on the production of new technological products.
The company produces building surface insulations using water-based and environmentally friendly polymers in accordance with the relevant quality standards.
Domestic Nanocoating Improves Metal’s Resistance to Corrosion
A knowledge-based company has developed an environment-friendly method to increase the resistance of metallic equipment and parts to corrosion by using a nanocoating.
One of the cost-effective and common methods for surface coating in different industries is the use of conversion coatings which, in addition to increasing the anti-corrosive quality of the metal, increases the paint’s adhesion to the surface.
Schiller Farayand Pars Company is the producer of the new zirconium nanocoating for metal equipment and parts.
Most commonly, phosphate or chromate conversion coatings are used, which studies have shown to be harmful to the environment and human health, apart from being economically unviable for the producer. Therefore, researchers were looking for another material to replace phosphate and chromate coatings such as zinc oxide, titanium oxide and vanadium oxide.
The chromate conversion coating is used on many metals and their alloys, but the main problem is its toxicity. One of the toxic compounds created by this coating is hexavalent chrome, which is carcinogenic.
Phosphate coating (also known as zinc phosphate coating) is not intrinsically toxic, but the post-treatment can give rise to poisonous chemicals that threaten human health.
Zirconium coatings produced by the domestic company are a good alternative because, unlike phosphate and chromate coatings, they do not create environmental problems and the coating process is done at ambient temperature and requires less time compared with other methods.
Another important feature of zirconium coatings is their lower weight compared with chromate and phosphate coatings.
Creating a coating with a thickness of less than 100 nanometers on metal surfaces, the absence of substances harmful for human health and the environment, and the lower cost of application are among the advantages of the Iranian nanocoating.
The company claims that applying a very thin layer of coating (in nanometers) on steel, aluminum and galvanized surfaces improves the adhesion of the organic coating, increases resistance to paint corrosion and prevents the paint’s cathodic separation.
Nano Glass, Windows Help Slash Energy Consumption
Two domestic companies have produced a nano glass and window that substantially reduce energy wastage in all seasons.
The energy-efficient glass has much lower heat transfer than ordinary glass as it prevents the entry and exit of heat and cold in different seasons, the news portal of the Vice Presidency for Science and Technology reported.
This is the reason behind using shades and curtains in houses to prevent the inflow of the sun’s heat in the summer and the outflow of heat in the winter.
The domestic nano glass named Eco Star, produced by Kaveh Glass Company, offers transparent thermal insulation that plays a big role in reducing energy consumption in buildings.
Very thin flute glasses are layered with the company’s advanced equipment to increase their heat control efficiency.
The domestic glass can be used in the facades of residential buildings, offices, schools, hotels and hospitals.
Eco Star glass helps curb the wastage of thermal energy, protect the environment by lowering energy use, prevent fogginess and reduce gas and electricity bills.
The appearance of Eco Star glass is similar to that of ordinary double-glazed glass in terms of both light transmission and reflection.
Nano UPVC Doors and Windows
Another domestic company has produced a set of Unplasticized PolyVinyl Chloride (UPVC) doors and windows that are highly durable and effective in optimizing energy consumption.
Shahin Sazeh Fajr Company produces profiles for windows and doors reinforced with nanoparticles.
The incorporation of nanoparticles has increased the impact resistance of this product. These profiles are also used in the production of various industrial and household products.
Other fields using UPVC include dental, pipe production and cable insulation. In the construction industry, it is mainly used to produce frames for double-glazed windows.
