Abstract

"MéTODO E COMPOSIçãO LUBRIFICANTE úTIL PARA MELHORAR A RESISTêNCIA AO DESGASTE DAS SUPERFìCIES METáLICAS E MANTER UM AMBIENTE HIDROLITICAMENTE ESTáVEL NO EQUIPAMENTO DE REFRIGERAçãO". Um método para melhorar o desgaste de superfícies metálicas e manter um ambiente hidroliticamente estável no equipamento de refrigeração durante a operação do equipamento. O método envolve colocar em contato as superfícies metálicas com uma carga base lubrificante de éster que compreende combinações de ésteres de neopentil glicol e ácido 2-etilexanóico e neopentil glicol e pelo menos um ácido de cadeia linear de quatro a dez átomos de carbono e tendo uma viscosidade de cerca de ISO 7-10. O lubrificante pode também ser usado em um fluido de trabalho com um fluido de transferência de calor do grupo flúor isento de cloro tal como 1,1,1,2-tetrafluoroetano.
