    摘要： The present invention provides a process for producing a water-miscible metalworking fluid involving combining about 90 wt.% to about 5 wt.%, based on the weight of the fluid, of water and one or more additives chosen from plasticizers, chelating agents, biocides, surfactants, dispersants, dyes, odorants, extreme pressure agents, anti-oxidants and corrosion inhibitors with about 10 wt.% to about 95 wt.%, based on the weight of the fluid, of a polyether polyol produced by mixing an active hydrogen compound with a double metal cyanide (DMC) catalyst in a reactor vessel, charging to the reactor vessel a mixture containing two or more alkylene oxides to activate the catalyst, and continuously feeding one or more alkylene oxides to produce the polyether polyol, wherein a 1% solution in water of the polyether polyol has a cloud point of from greater than about 32°C to less than about 53°C, the polyether polyol has a number average equivalent weight of from greater than about 1,000 Da to about 10,000 Da, and a four-hour aerosol inhalation exposure to the polyether polyol has a LC50 of greater than about 5 mg/L. The water-miscible metalworking fluid produced by the inventive process may find use in cooling and/or lubricating metal surfaces during one or more of grinding, cutting, boring, drilling and turning of metal parts.

    摘要： The present invention relates to improved metallurgical powder compositions that incorporate solid lubricants, methods for preparing and using the same, and methods of making compacted parts. Ejection properties, such as stripping pressure and sliding pressure, of compacted parts can be improved by using the solid lubricants. The solid lubricants contain polyalkylene- polyalkylene oxide block copolymer lubricants or a combination of polyalkylene-polyalkylene oxide block copolymer lubricants and at least one additional lubricant. The polyalkylene-polyalkylene oxide block copolymer lubricants include at least one block A of a linear or branched polyalkylene chain having from about 5 to about 500 carbon atoms, and at least one block B of an alkylene oxide chain having a formula -[O (CH2) r]m- , or -[(CH2)rO]m - . The polyalkylene block copolymer lubricants can have a formula represented as A-B or A-B-A.
