A domestic knowledge-based company has produced nanocoatings for protecting buildings from damages and extending its lifespan.
Nanocoatings produced by Sepahan Nano Faraz Company can help prevent the formation of scales and flakes on a building’s surface, reduce the growth of fungus, mold and algae, and block moisture from penetrating a building’s wall, the news portal of the Vice-Presidency for Science and Technology said.
Stains and oily pollutants mar the beauty of buildings’ façades made with concrete, wood, brick, tiles and other materials, which can be preserved with the help of the nanocoating.
Also known as ceramic coating, the nanocoating is applied as a surface layer in both liquid and solid forms to repel polluting dry particles, water, oil and dirt.
Revitalizing dark stone surfaces, protecting internal and external walls, especially of public places like schools, hospitals, mosques and ancient monuments, and helping construction contractors and owners optimize energy consumption are the most important benefits of using this domestic product.
Depending on the type and mode of application, a property’s mechanical and functional efficiency is retained and the appearance of materials and structures is preserved.
The use of waterproof coatings on all kinds of building materials will reduce the excessive accumulation of water on their surface and increases a building’s lifespan.
Recently, the development of products based on nanotechnology has expanded significantly in the domestic construction sector and numerous knowledge-based companies are active in this field.
Domestic Refractory Ceramics Prevent Currency Outflow
A knowledge-based company has produced industrial refractory ceramics, which prevented a significant currency outflow from importing counterparts.
These ceramics are used in various advanced industries and modern manufacturing processes, according to a member of the Board of Directors of Evarplast Komesh Company.
“Using refractory ceramics in places where there is a possibility of fire or high heat can be very economical and safe [due to their higher resistance compared with metals and other materials],” Nahid Chegeni was also quoted as saying by the news portal of the Vice-Presidency for Science and Technology.
Refractory ceramics show good resistance in environments with very high temperatures and can withstand physical wear and corrosion caused by chemical agents, hence they are used to line hot surfaces inside industrial equipment and furnaces.
These ceramics can be used in automotive, railroad, oil, gas, petrochemical, wood and furniture, printing and packaging, textile, electrical, electronic and telecommunication industries. They are essential to petrochemical production and gasoline refining.
Chegeni said refractory ceramics have many other features such as excellent resistance to oxidation and corrosion, high thermal insulation and mechanical resistance, low thermal expansion and excellent wear resistance.
Refractory ceramics can show high resistance to chemical compounds, corrosion and pressures applied during the manufacturing processes. They are mainly used in industries dealing with fire, especially in industrial furnaces, as they can withstand 600-2,000 degrees Celsius.
The company official noted that the thin industrial refractory ceramic has high torsion strength, electrical shock resistance, electrical insulation and thermal tolerance.
“The production of refractory ceramic production has created many directly and indirect jobs,” she said, without further elaboration.
Domestic Flame Monitoring System Matches Foreign Quality Cheaply
A knowledge-based company has developed a flame monitoring system that helps monitor the flame in equipment such as power plant turbines, where the continuity of the flame is vital.
“Typically, a flame monitoring system consists of one or more sensors and a trigger. The function of the starter or amplifier is to receive a signal from the flame detector sensor and announce its status," Mehdi Arianfard, a member of the board of directors of Sang Chin Zahedan Company, was quoted as saying by the news portal of the Vice-Presidency for Science and Technology.
Gas turbine is one of the most important pieces of equipment in the oil, gas and energy industries. The important tasks of monitoring and evaluating its efficient performance are handled by the flame monitoring system.
The color of the flame varies from infrared to ultraviolet, depending on the type of fuel used. As the fuel used by turbines is natural gas, its flame has more ultraviolet components.
With the production of this strategic and practical system, there is no need for foreign counterparts.
“South Pars Gas Company has replaced a foreign system with a domestic one for monitoring gas turbines,” he added.
In addition to turbines, the flame monitoring system is also used in furnaces.
“Currently, we can meet the needs of the country without the need for imports. The domestic system has prevented a large amount of capital outflow,” Arianfard said.
“While matching the quality of foreign models, it has been marketed at a lower price. It cost more than $2 million a year to import foreign counterparts.”
