A knowledge-based company has produced a smart self-healing asphalt (also known as rubber bitumen) that is cheaper than foreign counterparts.
The smart asphalt improves the quality of roads, reduces accidents and lowers the cost of repairs, according to one of the directors of the Zarrin Bitumen Technology Company.
“Infrastructures related to transportation are one of the important foundations of progress and development of a country,” Masoud Alizadeh was also quoted as saying by the news portal of the Vice Presidency for Science and Technology.
He noted that the company has endeavored to develop the most up-to-date technologies in this field.
“Repairing road and asphalt damage has long preoccupied domestic experts. Apart from the heavy cost of repairing them, it also leads to accidents, injuries and deaths,” he said.
According to Alizadeh, the company’s asphalt products use the polymerization method that does not face the problems related to old asphalt.
“One of the important features of the new generation asphalt is its self-healing property. That is, it can return to its original state after suffering damage,” he said.
“Another feature of this knowledge-based product is its higher width and durability. The smart asphalt is more resistant to freezing and has anti-skid capability, which can lower road accidents.”
Alizadeh said 100,000 tons of this product have been used in Mashhad and other cities of Khorasan Razavi Province.
“Foreign asphalts using the polymerization method are usually 250% more expensive than ordinary asphalt, while the price of the domestic knowledge-based product is only 15% higher,” he said.
Nano Concrete Flooring Cut Above Rivals
A knowledge-based company has used nanotechnology to produce a concrete flooring that offers a superior alternative to ordinary concrete flooring.
The resistance, durability and lifespan of these nano-based concrete flooring are higher than those of foreign and domestic counterparts, which help reduce overall costs for users as it remains in optimal conditions for a longer period, the news portal of the Vice Presidency for Science and Technology reported.
Manufactured by Aptus Iran Company with the support of the vice presidency’s Technology Development Headquarters, the product can be used in the warehouses of ports and docks where floorings experience extremely high pressure and strong mechanical shocks. Excellent mechanical strength, anti-skid capability, low weight, impermeable surface, high resistance to impact and eye-catching appearance are among the features of this nano-based concrete flooring.
Fine-grained materials used on the top layer make it resistant to abrasion that help maintain its appearance for a longer period. As a result, these floorings are also suitable for parking lots, pavements, intersections, staircases, ramps, toll stations, refineries, gas stations and for limiting vehicle speed on roads and highways.
With over 250 employees, Aptus Iran Company also provides competitive, high quality building materials and engineering services.
Nano-Based Catalytic Converters
A domestic knowledge-based company has produced a catalytic converter based on nanotechnology, which is considerably cheaper than its foreign counterparts.
With the beginning of the winter season and air inversion, major industrial cities face serious challenges regarding air pollution, which has a negative effect on the physical and mental health of their citizens.
Inhaling polluted air, especially airborne particles, can cause cardiovascular and pulmonary diseases, and cause serious disruption in medical and industrial sectors. For this reason, city managers are looking for ways to minimize air pollution.
Part of this serious problem can be solved with the help of emerging technologies and high-tech Iranian products. Nanotechnology boosts the efficiency of catalytic materials and improves the performance of catalytic converters.
For instance, nano-based catalytic converters expedite oxidation reduction, turn exhaust gas emissions into less toxic pollutants and curb air pollution.
Parto Farazan Avizeh Kimia Company can supply catalytic converters to domestic automobile companies at one-third of the price of its foreign counterparts.
While they are commonly used in passenger vehicles, other devices and machines that worsen air pollution such as mining equipment, buses, locomotives, motorbikes, trucks, electrical generators and even ships can also be equipped with this product.
Usually, these vehicles and machines use a catalytic converter in their exhaust, but in some cases, two catalytic converters are used to reduce a larger volume of air pollution.
In this product, all precious metals, including platinum, palladium and rhodium, are distributed in the form of nanoparticles on a catalytic base with high porosity.
Another important advantage of catalytic converters is that they can transform about 98% of harmful and toxic gases produced by vehicles and machines into less harmful and toxic gases.
