O dissulfeto de molibd\u00eanio \u00e9 um importante lubrificante s\u00f3lido, especialmente adequado para aplica\u00e7\u00f5es de alta temperatura e alta press\u00e3o. Ele tamb\u00e9m \u00e9 antimagn\u00e9tico e pode ser usado como fotocondutor linear e como semicondutor com propriedades condutoras do tipo P ou N, com retifica\u00e7\u00e3o e transfer\u00eancia de energia. O dissulfeto de molibd\u00eanio tamb\u00e9m \u00e9 usado como catalisador para a desidrogena\u00e7\u00e3o de hidrocarbonetos complexos.
Ele tamb\u00e9m \u00e9 conhecido como o \"Rei dos Lubrificantes S\u00f3lidos Avan\u00e7ados\". O dissulfeto de molibd\u00eanio \u00e9 um p\u00f3 s\u00f3lido feito de p\u00f3 concentrado de molibd\u00eanio natural que foi quimicamente purificado e teve sua estrutura molecular alterada.
O produto \u00e9 preto com uma cor cinza levemente prateada, com brilho met\u00e1lico, suave ao toque e insol\u00favel em \u00e1gua.
O produto tem as vantagens de boa dispers\u00e3o, sem liga\u00e7\u00e3o, pode ser adicionado a todos os tipos de graxa, formando um estado coloidal sem liga\u00e7\u00e3o, podendo aumentar a lubricidade da graxa e a press\u00e3o extrema. Tamb\u00e9m \u00e9 aplic\u00e1vel a condi\u00e7\u00f5es de trabalho mec\u00e2nico de alta temperatura, alta press\u00e3o, alta velocidade e alta carga, para prolongar a vida \u00fatil do equipamento.
O dissulfeto de molibd\u00eanio \u00e9 usado para materiais de fric\u00e7\u00e3o, a principal fun\u00e7\u00e3o \u00e9 reduzir o atrito em baixas temperaturas, o atrito em altas temperaturas, a quantidade de perda por queima \u00e9 pequena, f\u00e1cil de volatilizar nos materiais de fric\u00e7\u00e3o.
Redu\u00e7\u00e3o de atrito: o tamanho da part\u00edcula de dissulfeto de molibd\u00eanio atingiu 325-2500 mesh por meio do processamento de esmagamento de fluxo de ar supers\u00f4nico, dureza de micropart\u00edculas de 1-1,5, coeficiente de atrito de 0,05-0,1, de modo que pode ser usado em materiais de atrito e pode desempenhar um papel na redu\u00e7\u00e3o do atrito.
Atrito: O dissulfeto de molibd\u00eanio n\u00e3o \u00e9 condutor e existe como um copol\u00edmero de dissulfeto de molibd\u00eanio, trissulfeto de molibd\u00eanio e tri\u00f3xido de molibd\u00eanio. Quando a temperatura de um material de atrito aumenta muito devido ao atrito, as part\u00edculas de tri\u00f3xido de molibd\u00eanio no copol\u00edmero se expandem \u00e0 medida que se aquecem, aumentando o atrito.
Anti-oxida\u00e7\u00e3o: O dissulfeto de molibd\u00eanio \u00e9 obtido por meio de uma rea\u00e7\u00e3o abrangente de purifica\u00e7\u00e3o qu\u00edmica, seu valor de pH \u00e9 de 7-8, levemente<\/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<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
