TRICOT MESHES IN JEWELRY AND INDUSTRY

There are several uses for precious metal mesh, its reliability, durability and mainly the metals that compose it, such as gold, silver, platinum and PGMs, give knitted mesh unique properties. 

Jewelry and fashion
This type of mesh is used in haute couture as a textile and in high-end designs to build unique and distinguished pieces.

Electromagnetic shielding
Knitted mesh is a way to eliminate electromagnetic interference by shielding specialized sensors from external signals, reducing electromagnetic and radio frequency interference.

Filters for medical use
Due to their properties, this type of fabric is used in medical devices in order to purify and reduce infections, and to filter and protect electronic components sensitive to electromagnetic interference.

Chemical industry
Precious metal knitted meshes are often used as filtration media in the chemical industry and as catalysts in the production of chemical agents.

The Ostwald Process: Foundation of Industrial Chemistry

The Ostwald process, named after the pioneering chemist Wilhelm Ostwald, is the cornerstone of industrial nitric acid production. This method involves several sequential steps where ammonia is oxidized to nitric oxide (NO), which further reacts to form nitrogen dioxide (NO₂). Ultimately, nitrogen dioxide dissolves in water to yield nitric acid.

The Vital Role of Platinum Tricot Meshes

Platinum tricot meshes play a critical role in the initial stage of the Ostwald process, where they act as catalysts for the oxidation of ammonia to nitrogen monoxide. Here’s how these meshes significantly enhance this essential reaction:

• Catalytic Efficiency: Platinum is chosen for its exceptional catalytic properties, especially in high-temperature environments required for this process. The tricot mesh structure provides a large surface area, maximizing contact between the reactants (ammonia and oxygen) and the catalyst. This configuration promotes efficient conversion by lowering the energy needed for the reaction.

• Temperature Regulation: The oxidation of ammonia to nitrogen monoxide is exothermic and requires precise temperature control (typically around 850-900°C). Platinum tricot meshes help maintain these elevated temperatures, ensuring optimal reaction rates and minimizing unwanted side reactions.

• Durability and Reliability: Industrial processes demand catalysts that withstand harsh conditions, including high temperatures and chemical reactivity. Platinum tricot meshes are renowned for their durability and resistance to degradation, ensuring long-term operational reliability in production facilities.

Broad Applications Across Industries

Beyond their pivotal role in nitric acid production, platinum find diverse applications across various industrial processes:Hydrogenation Reactions: Widely used in the hydrogenation of organic compounds, critical in chemical and pharmaceutical manufacturing.

• Catalytic Converters: Integral to automotive catalytic converters, where they convert harmful emissions into less harmful gases, contributing to cleaner air.

• Petroleum Refining: Facilitate the refining of petroleum products, enhancing the yield and quality of fuels

• Electrochemical Processes: Employed in fuel cells and electrolyzers, supporting sustainable energy solutions through efficient electrochemical reactions. and petrochemicals.
