摘要:
The present invention makes the insertion perception during actual surgery to be equivalent to the insertion perception of a catheter into a blood vessel model when water is used as the circulating fluid. A lubricant regulating fluid primarily composed of water is mixed with an aqueous metal salt and a surfactant as a lubricant regulating agent of the lubricant regulating fluid. A cationic surfactant, an anionic surfactant, a nonionic surfactant, or a dipolar ionic surfactant may be used as the surfactant. Also, the metal salt may be an alkaline metal salt, an alkaline earth metal salt, an aluminum salt, a ferric salt, or the like. In an example, the lubricant regulating fluid obtained by mixing an aqueous metal salt with water is prepared, and the lubrication and non-adherent properties of a catheter into a simulated blood vessel model are improved.

The invention relates to a method for the production of a cooling lubricant emulsion mixed with water, used for metal cutting, whereby a) 2-15 parts by weight of a water-miscible concentrate of a coolling lubricant emulsion are mixed with 98-85 parts by weight of water, so as to obtain a mixture comprising 100 parts by weight, and then b) one disperses 1-14 parts by weight of a non water-miscible native-based cutting oil are dispersed, with strong shearing action into mixture a). The cutting oil is preferably chosen from oxidation-stabilized fatty acid glycerides in the form of triesters with three fatty acids with 14-22 C-atoms per fatty acid, and oxidation-stabilized diesters with two fatty acids with 12-22 C-atoms per fatty acid. The invention further concerns a cooling lubricant emulsion that can be produced by this method, and its use for metal cutting.
摘要:
The invention is directed to an aqueous lubricant concentrate composition which is usable for the preparation of an aqueous lubricating solution for lubricating conveyor belts and conveyor chains in the food and beverage industry. The composition comprises at least one monoamine compound as the main lubricating agent; an effective amount of a deposition-preventing component capable of preventing the deposition of solids from the lubricating solution under lubricating application conditions at least to such an extent that said lubricating application is not impaired by such depositions, without impairing the lubricating film-forming properties of the aqueous lubricating solution, and optionally further comprises a disinfectant, and other customary additives.

A grease composition for a constant velocity joint, characterised in that it contains from 0.05 to 30 percent by weight of sodium thiosulphate with respect to a base oil and urea-based thickener.
摘要:
A process for treating an aluminium can, comprising the steps of cleaning with an aqueous acidic or alkaline solution, drying and subsequently conveying the cleaned and dried can via automatic conveying equipment to a location where it is lacquered or decorated by printing or both. At least one exterior surface of the can, prior to the last drying of the surface before automatic conveying, is contacted with a lubricant and surface conditioner forming composition comprising ethoxylated, hydrogenated castor oil triglycerides, and the can is then dried without subsequent rinsing, thereby forming a film on the can to provide the surface of the can after drying with a reduced coefficient of static friction compared to an otherwise identical sequence of treatments where the lubricant and surface conditioner forming composition is substituted with water.
