Hot efficacy testing fluid comprising a gas phase prevention

摘要

The present invention relates to a formulation which provides protection against corrosion of various forms in both the liquid and vapor phases . Such formulations , engine components or fuel cell system is intended to be used when being processed prior to final assembly or stored in " break-in " or "hot potency test" . The invention also includes a dilute solution not concentrate only . By synergistic combination of a combination of an inorganic ammonium derivatives and monocarboxylic acids or dicarboxylic acids , protection period increases dramatically . Thus , if the engine parts prior to assembly is shipped or stored , it is possible to more long-term storage . Use of the invention described is for preconditioning the metal surface , also provides protection as thereafter the liquid was almost completely removed . The optionally other conventional or organic corrosion inhibitors can be added . It is also possible to add a freezing point depressant , in addition to antifreeze , it is possible to achieve high vapor protection level .
