si nanoparticles is a particle with dimensions of about 1 to 100 nanometers. In addition to the metal type, insulators and semiconductors, nanoparticles also contain composite nanoparticles such as core structures. Also, nanoparticles, nanomolecules, and nanofluids are the only forms of nanoparticles. Nanoparticles are low nanoscale sizes. Nanoblores and semiconductor quantum dots are also subsets of nanoparticles.Nanoparticles are characterized by three characteristics: type size and volume concentration. For example, for nanoparticles used in trans volumetric concentrations, 0.1 to 1% per liter is a good amount. Determining the specifications of nanoparticles is necessary to control their synthesis and application.
What are si nanoparticles?
Feature of si nanoparticles have found their place in many basins, including pharmaceutical systems, catalysts, biological therapies, photographs of living things, coloring, sensors, liquid armor, and as fillers in composite materials. The method of producing porous and suspended silica particles by TEOS hydrolysis was first reported in 1968. Later, the concentration of TEOS, alkaline environment and water in relation to the size of the obtained silica nanoparticles were studied.
Also, the shape and size of silica particles can be controlled by reaction parameters such as time, temperature and solution concentration. In addition to TEOS, sodium silicate solution can be used to produce silica particles. Rice husks, rice bran, pulp ash and half-burnt straw ash are among the disposable materials that can be used in the production of sodium silicate solution. Sodium silicate particles are precipitated by acids such as hydrochloric acid as a precipitator from sodium silicate solution. Carbon dioxide can also be used as a precipitator.
Specifications of si nanoparticles for export
According to ISNA, one of the companies active in the field of nanotechnology with an export volume of about $ 17 million has been the most successful company exporting Best si nanoparticles in 2020 . Nanostechs, nano granules and nanocomposites were among the company’s export nano products in 2015. The company’s focus is on the production of various types of masterbatch and polymer additives, industrial and sanitary nanocomposites with an annual production capacity of 180,000 tons. In 2015, with the export of $ 17 million of its products, this company has the highest rate of export of nano products among Iranian companies. Tajikistan, Turkmenistan, Afghanistan and Uzbekistan have been among the target countries for the company’s exports.The company’s nanocomposite granules also have antibacterial properties, and the use of these products in the production of textiles will prevent the growth of bacteria. Zinc oxide nanoparticles have been used in the structure of these granules.
