A domestic engineering company has produced a machine that can make electronic components waterproof.
The Industrial Plasma Treatment Machine, produced by Basafan Engineering Company, lends waterproof properties to electronic devices and components used in different industries.
Creating hydrophobic surfaces, improving adhesion and lending anti-stain properties are among the features of the domestic machine, the news portal of Iran Nanotechnology Innovation Council reported.
Electronic devices and components are sensitive to moisture, so waterproofing them is crucial when a device is used in an environment with high humidity.
Many devices, such as circuit boards, telephones, headphones, electronic boards and electrical appliances, need this property to prevent any damage when it comes into contact with water or humidity.
The domestic plasma treatment machine has the ability to make two- and three-dimensional surfaces and objects waterproof, or can be used to produce waterproof products, especially in electronic or textile industries.
The machine also deposits a thin polymer layer on different surfaces to create slow-burning and anti-corrosion properties.
Plasma processing takes place in a chamber in a controlled atmosphere, under moderate vacuum and the use of gases. To do this, the surface is first cleaned and activated by a gas, or a mixture of gases ionized by a radio frequency generator. Then, depending on the desired characteristics, a suitable gaseous or liquid monomer is injected into the chamber. Monomer molecules are separated with the help of radio frequency energy and create free electrons, ions and free radicals. Radicals are absorbed and polymerized on the surface. Connecting ions and electrons for creating a chemical bond with molecules deposited on the surface helps form a layer on the surface with a thickness of between 30 and 300 nanometers.
Knowledge-Based Plasma Treatment Device
A knowledge-based company has produced wastewater treatment equipment using plasma and cavitation technology that purifies different types of wastewater for reclamation.
It can be used for the removal and neutralization of organic pollutants in industrial, mining, household and other wastewaters, purification of hospital effluents containing toxic compounds and treatment of contaminated and toxic water with heavy metals and microorganisms.
The equipment is produced by Pishro Fanavar Tav Asia (also known as Panta Plasma) with the support of the Iran Nanotechnology Innovation Council, the news portal of the Vice Presidency for Science and Technology reported.
The company claims that the facility eliminates all types of harmful microorganisms, polluting organic compounds and heavy metals in wastewater.
The ability to destroy stable materials, using limited space for the purification process, avoiding the use of chemicals, lowering cost compared with counterparts, removing heavy metals and reducing sludge volume during treatment are among the advantages of the new facility, the company says.
The blending of plasma and cavitation technologies in the equipment reportedly results in more efficient purification compared to other systems.
Plasma technology is the use of high-voltage electric discharge by creating high-energy points in water using methods such as arc discharge, glow discharge and dark discharge in a pulsed manner without increasing the temperature of the fluid, which will reduce energy consumption and increase discharge power in a shorter time compared with other methods.
The cavitation technology helps form macro/micro cavities by using cavitation modules (orifice pellet, venturi, rotary and vortex) and creates a pressure difference. With the explosion of these cavities, high energy points are created in the fluid.
The pulsed plasma in the new facility eliminates pollutants by creating an electrical discharge in the water.
The company said it was able to boost efficiency by synergizing plasma and cavitation technologies using combined geometry and controlling specific conditions.
Unique Hybrid Mill Developed by UT Researchers
Domestic researchers have produced a unique hybrid mill that creates nanopowder from different substances for use in research centers and industries.
The mill has been developed by the researchers of the University of Tehran (UT), in cooperation with the Technical and Vocational University and the Materials and Energy Research Center, according to the director of UT’s Nanobiophotonics Research Laboratory.
“By simultaneously using a bullet and ultrasonic power, the hybrid mill can produce nanopowder from various ceramic and metal compounds while maintaining their properties,” Mohammad Mohammadi Masoudi was also quoted as saying as IRNA.
Nanopowders have individual particles at the nanometer scale. Due to their small sizes, these powders have extraordinarily high surface area-to-volume ratio that changes their physical-chemical properties compared with macroscale powders.
The ability to control nanoparticle size by changing milling frequency and time is the main feature of this hybrid mill, which can also handle mechanical alloying.
As it allows nanoparticles to penetrate into metal substrates for creating different coatings, the hybrid mill can be used in metallurgy, photonics, component manufacturing and automotive industries.
According to Mohammadi, the hybrid mill does not have a domestic or foreign counterpart and is the first of its kind.
“The device will be sold to universities and research centers with a three-year warranty,” he said.
