Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of
(A) water-soluble ethoxylated organic material selected from the group consisting of ethoxylated fatty acids, salts of ethoxylated fatty acids, ethoxylated alcohols having at least 4 carbon atoms and containing up to 20 moles of condensed ethylene oxide per mole of alcohol, ethoxylated alkyl alcohol phosphate ester, and mixtures thereof; and (B) an amount of hydrogen peroxide effective to prevent deterioration of the composition by the action of microorganisms,
gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition may be advantageously increased by adding a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.
Abstract:
A machining oil composition comprises at least two ingredients, that is a lubricating base oil and a salt selected from sulfonates of alkali metals and the like. The composition may further comprise a metal composition selected from thiophosphates and the like, and/or sulfur-based extreme pressure agents. Since no chlorine-based extreme pressure agent is contained, little problem on the environmental pollution or the damage of incinerators is involved. The composition exhibits good machining or cutting performance.
Abstract:
A graphite-free lubricating oil which comprises a base oil having dispersed therein 10 to 40% by weight of a carbohydrate and/or a derivative thereof whose particle size ranges from 10 to 150 µm, 2 to 20% by weight of a film-boosting agent and 0.1 to 20% by weight of a dispersant. Moreover, the lubricating oil is free of black-colored substances such as graphite. Therefore, the oil permits the improvement of working surroundings and exhibits excellent properties such as formability through forging almost comparable to or even greater than that of the commercially available graphite-in-oil type lubricating oils. The lubricating oil can be used instead of the graphite-containing lubricating oils for warm forging, hot forging, rolling, tube-manufacturing, drawing and extrusion in place of the graphite-containing lubricating oils and ensures the improvement in the working surroundings and excellent lubricity.
Abstract:
This invention is directed to a liquid metal and oil treating composition and to the process of preparing the composition. In the process there are first mixed together a vegetable oil such as cashew oil, anoleate ester such as magnesium oleate, and Ingredient A which is material selected from the group consisting of (a) ferric chloride, (b) at least one of pulverized lead oxide, ferric oxide, iron carbide, chromium carbide and tungsten carbide dispersed in an aqueous solution of acid selected from the group consisting of hydrochloric acid, perchloric acid and sulfuric acid. The acid solution is concentrated, preferably containing about 40 volume % acid. The mixture is heated and stirred and then distilled. The residue is then heated to about 100-150°F, while adding to it, with stirring, an antioxidant, a polar hydrocarbon, a carbonyl, a carboxyl amide, a viscosity improver, at least one of a tackifier and a sulfonate, and a petroleum oil until a homogeneous liquid is obtained.
Abstract:
An aqueous lubrication treatment liquid for a cold plastic working of a metallic material comprises 4 to 160 g/l of a metallic soap, 50 to 400 g/l of a solid lubricant, 0.5 to 40 g/l of a dispersing surfactant for the metallic soap and the solid lubricant, and optionally a colloidal titanium compound in an amount of 10 ppm or more in terms of titanium and 5 to 150 g/l of a binder.
Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition as described above, and of other similar surface friction reducing treatments for aluminum containers, may be advantageously increased by adding a biocidal agent, preferably hydrogen peroxide, and a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.
