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 a water-soluble organic material selected from amine oxides and quaternary ammonium salts, fluozirconate, fluohafnate, or fluotitanate ion, and preferably also phosphate and 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:
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.
Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) ethoxylated phosphate esters, ions of aluminum, zirconium, iron, tin, and/or cerium, and (iii) a metal etching component 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.
Abstract:
Copper salts of thiodipropionic acid derivatives provide excellent multifunctional/antioxidant characteristics for lubricant compositions when incorporated therein.
Abstract:
A lubricant base oil composed of an ester. The ester includes a component (A) derived from trimethylolpropane in a molar percentage Amol % of 25 to 42 mol %; components (B) derived from monovalent straight-chain saturated fatty acids each having a carbon number of 8 to 12 in a molar percentage Bmol % of 33 to 55 mol %: and a component (C) derived from adipic acid in a molar ratio Cmol % of 12 to 34 mol %. The components (B) include lauric acid in a molar percentage of 5 to 50 mol %, and (BCOOH+CCOOH)/AOH is 0.90 to 1.02. AOH represents a hydroxyl equivalent of the component (A), BCOOH represents a carboxyl group equivalent of the components (B); and CCOOH represents a carboxyl group equivalent of the component (C).
Abstract:
A friction modifier composition for reducing friction in a lubricant comprising a fatty acid sorbitan ester that is solid or semi-solid. The fatty acid sorbitan ester is capable of being released into a lubricant at a rate of less than or equal to 0.15 grams per minute.
Abstract:
The invention relates to a process for producing a new type of high-quality hydrocarbon base oil of biological origin. The process of the invention comprises ketonisation, hydrodeoxygenation, and isomerization steps. Fatty acids and/or fatty acid esters based on a biological raw material are preferably used as the feedstock.
Abstract:
The present invention relates to a lubricant composition. The present invention more particularly relates to a fully miscible lubricant composition that comprise a polyether and a renewable raw material such as an unsaturated seed or vegetable oil.
Abstract:
A lubricant for conveyor chains, the lubricant consists of a mixture of a quantity of fatty acid, a quantity of amine, a quantity of polyglycol, and a quantity of hydrocarbon. The lubricant of the invention uses a direct application, without dilution, and forms a layer or film of lubricant on the surface of the conveyor chain so that the application is discontinued, in long intervals between the applications.
Abstract:
From not more than three blending stocks, it is possible to prepare a wide variety of mixtures of esters of hindered polyhydric alcohols that are especially valuable lubricants for chlorine-free fluorocarbon refrigerant heat transfer fluids, particularly Refrigerant 134a (1,1,1,2-tetrafluoroethane).
