2. Aplica\u00e7\u00f5es industriais<\/h3>\n

Desengorduramento de metais (utiliza\u00e7\u00e3o principal, ~60% do consumo global) O TCE \u00e9 um excelente solvente para remover gordura, \u00f3leos e ceras de superf\u00edcies met\u00e1licas (por exemplo, pe\u00e7as autom\u00f3veis, componentes aeroespaciais, instrumentos de precis\u00e3o). Possui elevada efici\u00eancia de desengorduramento e baixa tens\u00e3o superficial, tornando-o adequado para a limpeza de pe\u00e7as com formas complexas.<\/p>\n

Intermedi\u00e1rio qu\u00edmico utilizado na s\u00edntese de alternativas aos clorofluorocarbonetos (CFC), cloreto de vinilideno (mat\u00e9ria-prima para pl\u00e1sticos PVDC) e pesticidas. Serve tamb\u00e9m como mat\u00e9ria-prima para a produ\u00e7\u00e3o de percloroetileno (PCE), outro solvente industrial.<\/p>\n

Outras utiliza\u00e7\u00f5es: Anteriormente utilizado como agente de limpeza a seco (substitu\u00eddo pelo percloroetileno devido a preocupa\u00e7\u00f5es com a toxicidade), como solvente para adesivos, tintas e tintas de impress\u00e3o, e como refrigerante em alguns sistemas especializados.<\/p>","protected":false},"excerpt":{"rendered":"
