Abstract:
Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
