Abstract:
A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. An aqueous composition for forming the conditioner by contact with metal surfaces includes a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and polyacids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixtures thereof and at least one of the elements selected from zirconium, titanium, cerium, aluminum, iron, tin, vanadium, tantalum, niobium, molybdenum, tungsten, and hafnium in metallic or ionic form. In order to avoid formation of sludge in the aqueous lubricant and surface conditioner forming composition, the composition should contain as little as possible of materials containing phenanthrene rings, such as conventional surfactants made by ethoxylating resin. In order to assure the minimization of such surfactants in the aqueous lubricant and surface conditioner forming composition, surfactants containing phenanthrene rings should also be avoided or minimized in earlier cleaning stages.
Abstract:
The coefficient of friction of aluminum can surfaces after alkaline cleaning and drying can be substantially reduced by adding to the alkaline cleaner a mobility-enhancing additive, preferably a surface active quaternary ammonium salt with hydroxyethyl substituents on the quaternary nitrogen atoms. A can surface suitable for automatic conveying and high quality lacquer or printing ink adhesion can thereby be obtained, if desired, without including any substantial fluoride content in any treatment stage.
Abstract:
A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes (i) a water-soluble organic material selected from amine oxides and quaternary ammonium salts, ethoxylated castor oil derivatives, and imidazoline moiety-containing phosphonates and preferably also includes (ii) at least one of fluozirconate, fluohafnate, or fluotitanate ion, and (iii) phosphate and/or nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.

Abstract:
Clear water-soluble polymer compounds having a mean molecular weight higher than 10 and selected among the polyalkylene oxides, polyacryl amides, polymethacryl amides and the copolymers of acryl amide and/or methacryl amide with unsaturated organic carboxylic acids having 3 to 5 C-atoms are used in water-miscible and water mixed cooling lubricants to reduce mist formation.
Abstract:
A lubricating oil composition is described which comprises a major amount of an oil of lubricating viscosity and (A) at least about 1 % by weight of at least one carboxylic derivative composition produced by reacting (A-1) at least one substituted succinic acylating agent containing at least about 50 carbon atoms in the substituent with (A-2) from about 0.5 equivalent up to about 2 moles, per equivalent of acylating agent (A-1), of at least one amine compound characterized by the presence within its structure of at least one HN
Abstract:
A method of manufacturing a metal can, wherein a metal material coated with an organic resin film is subjected to single- or multi-stage deep drawing to manufacture a metal can, a saturated hydrocarbon lubricant is uniformly applied to the organic resin surface of a metal material coated with organic resin, the raw material is subjected to drawing after the coating, so that high lubricating properties can be obtained at the time of drawing with a small amount of coating, only the heating of the can after the forming makes it possible to remove most of the lubricant, printability and flavor retainability can be remarkably improved while a degreasing-washing process and the succeeding drying process, which have been indispensable in the conventional method, are dispensed with, and the resources of water and energy can be saved, thus offering a distinctively improved method of manufacturing the metal can in preventing environmental pollution.
