Iranian Company Produces Wear-Resistant Shoe Soles with Hydrated Silica
Precipitated silica nanoparticles are used in the soles of these shoes which increases resistance to wear and tear.
This technology can be used in the production of shoes and rubber, and industries like construction, paint, resin, coating and textile. The primary and main ingredient of this product is known as hydrated silica in the market.
The Iranian company has succeeded in receiving a nanoscale certificate and a knowledge-based certificate for its products.
Hydrated silica is a form of silicon dioxide, which has a variable amount of water in the formula. When dissolved in water, it is usually known as silicic acid. It is found in nature as opal (which has been mined as a gemstone for centuries), and in the cell walls of diatoms. It is also synthetically manufactured for use in toothpaste as an abrasive to assist in cleaning.
Hydrated silica can be dehydrated to produce silica gel [which is used as a desiccant. It is also used in various paints and varnishes and in the production of beer.
Hydrated silicas can form in nature through biotic processes primarily involving benthic microorganism activity in the oceans. However, there are several abiotic processes that form hydrated silicas, such as precipitating out of solution, forming a diagenetic alteration product, or replacing pre-existing minerals in sedimentary rocks.
