Dip Electrospinning Unit
0,00 €Introduction
Dip electrospinning unit (needleless electrospinning) is a large-scale nanofiber producer machine. Unlike conventional electrospinning which uses needle and syringe pump for nanofiber production, in this system, a rotary spinneret is immersed into the polymer solution bath and a high strength electric field is applied to the solution bath and collector. This results in the formation of numerous jets from the spinneret and the nanofibers form on a collector.
Lab Electrospinning Unit
0,00 €Introduction
Lab Electrospinning Unit is a full-automatic laboratory electrospinning instrument which is able to produce different polymer nanofibers. This system makes use of electrostatic and mechanical force to spin fibers from the tip of a fine spinneret. The spinneret is maintained at a positive or negative charge by a DC power supply. When an applied electrostatic charge overcomes the surface tension of the solution, the polymer jet is formed. A rapidly rotating collector results in aligned nanofibers while stationary collector results in randomly oriented fiber mats.
Biodegradable Compound
0,00 €Introduction
Petroleum resources are limited and the excessive use of non-biodegradable polymers has caused serious environmental problems. Therefore, degradable and/or biodegradable polymers have received more attention these days. Since synthetic polymers are expensive, the focus is mainly on natural polymers which are inherently biodegradable and can be promising candidates to meet different requirements. Among the natural polymers, starch is of main interest. It is regenerated from carbon dioxide and water by photosynthesis in plants. Due to its complete biodegradability, low cost, and renewability, starch is considered as a promising candidate for developing sustainable materials. Addition of starch to the synthetic polymers creates biodegradable feature but decreases mechanical properties. To deal with this problem, nanofibers are added to the polymers.
Antibacterial Chinawear with Hydrophobic Coating
0,00 €Introduction
Washing porcelain dishes after a meal is a tedious work. During washing, greasy porcelain dishes are very slippery in hand. Also, in some cases fat stains remain after washing. Moreover, surface of a dish due to direct contact with the hands or leftovers is a good place for growth of bacteria and fungi. The aforementioned problems can be obviated with the aid of nanotechnology; to do this, chinaware with hydrophobic and antibacterial surfaces are produced by the addition of silicon and zinc nanoparticles, respectively. The chinaware produced by this company are classified in two different groups:
- Hydrophobic chinawear
- Antibacterial chinawear
Antibacterial Air Filter for Evaporative Cooler
0,00 €Introduction
A particulate air filter is a device composed of fibrous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air. Antibacterial air filters are widely used to prevent the growth of bacteria inside the evaporative coolers; the growth of bacteria is attributed to the wet environment inside the coolers. By addition of silver nanoparticles to the filter cloth, silver ions are released within its structure and prevent the growth of bacteria. The concentration of silver ion in this product is 165 ppm.
HYDROCHLORIC ACID
0,00 €Hydrochloric acid is a colorless inorganic chemical system with the formula H2O:HCl. Hydrochloric acid has a distinctive pungent smell. It is mainly produced as a precursor to vinyl chloride for PVC. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride practically dissociates completely in solution.
Fuel oil-MAZUT
0,00 €Mazut is a heavy, low quality fuel oil which is the residue from distillation of gasoline, ligroin, kerosene, and diesel oil fractions from petroleum. It comprises all residual fuel oils, including those obtained by blending. Its kinematic viscosity is above 10 cSt at 80°C. The flash point is always above 50°C and the density is always higher than 0.90 kg/l.
CAUSTIC SODA
0,00 €Sodium hydroxide or caustic soda is a white solid substance with the chemical formula NaOH and it is obtained through the process of electrolysis of sodium chloride soluble in the electrolytic containers. It is called caustic soda because it is highly corrosive in nature. It is available in many forms in the industry, and the most common forms are caustic soda flakes and caustic soda pearls. Sodium hydroxide as a strong base, is considered from one of the most important industrial chemicals and strong absorbent of moisture.
SODA ASH (SODIUM CARBONATE)
0,00 €Sodium carbonate (also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate), Na2CO3, is the water-soluble sodium salt of carbonic acid.

Spot Welding Electrode Tip
0,00 €Introduction
This product is made of a nanocomposite consists of copper alloy reinforced with aluminum oxide nanoparticles with the average size of 10 nm, which are uniformly distributed in the copper matrix. Aluminum oxide is produced through a process in which oxygen reacts with aluminum in the copper lattice in the solid state. This method, in comparison with other techniques, has the best particle size and distribution. Aluminum oxide is very hard, thermally stable and insoluble in copper. These particles not only increase the copper alloy strength but also have no significant effect on reducing the thermal and electrical conductivity of copper. The electrode tips are produced in different male or female types by cold forming process or in some cases by the machining process.
Heavy Truck Air Filter
0,00 €Introduction
The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic fibers (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine nanofibers (typically 50 to 400 nanometers in diameter). In this method, before the pleating process, the filter paper is covered with a layer of polymeric nanofibers with diameter of 50 to 300 nanometer by using an electric field. Nanofibers form because of the existence of a large potential difference.
