Principais \u00e1reas de aplica\u00e7\u00e3o
1. Aplica\u00e7\u00f5es industriais
- Blindagem electromagn\u00e9tica: Utilizada em equipamentos electr\u00f3nicos e camadas de blindagem de cabos para evitar interfer\u00eancias electromagn\u00e9ticas.
- Filtragem e separa\u00e7\u00e3o: Utilizado como filtro para gases e l\u00edquidos (por exemplo, em equipamentos petroqu\u00edmicos e de prote\u00e7\u00e3o ambiental).
- El\u00e9ctrodos de bateria: Algumas baterias utilizam uma malha de cobre como coletor de corrente.
2. Investiga\u00e7\u00e3o cient\u00edfica e experi\u00eancias
- Equipamento experimental: tais como redes catal\u00edticas e redes de aquecimento em experi\u00eancias qu\u00edmicas.
- Grelhas de microsc\u00f3pio: grelhas de suporte de amostras para microsc\u00f3pios electr\u00f3nicos de transmiss\u00e3o (TEM).
3. Prote\u00e7\u00e3o m\u00e9dica e ambiental
- Materiais antibacterianos: utilizados na superf\u00edcie de equipamento m\u00e9dico e em filtros de \u00e1gua.
- Tratamento de \u00e1guas residuais: utilizado como material eletrol\u00edtico ou de filtra\u00e7\u00e3o.
4. Equipamento de dissipa\u00e7\u00e3o de calor
- Dissipadores de calor, permutadores de calor: utiliza\u00e7\u00e3o de elevada condutividade t\u00e9rmica para melhorar a efici\u00eancia da dissipa\u00e7\u00e3o de calor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"

Copper mesh Copper mesh is a metallic mesh material woven from copper wires, possessing properties such as electrical conductivity, thermal conductivity, non-magnetic properties, wear resistance, and corrosion resistance.
