Abstract:
An aqueous antimicrobial conveyor track lubricant composition is provided, comprising: (a) an effective lubricating amount of neutralised C8-C22 fatty acid soap; (b) an effective antimicrobial amount of silver ions; (c) an amount of base sufficient to set the pH of the composition at from 8 to 11. Furthermore, the invention provides a concentrate, which upon dilution with water, forms this aqueous antimicrobial composition. The invention also relates to the use of silver ions as an antimicrobial constituent in a soap based conveyor track lubricant composition.
Abstract:
According to the method of the invention, first a paste is produced from a plastics dispersion and fillers in order to form the plastics sliding layer. This paste is free from organic solvents and is applied to a sintered porous metal layer. The resultant multi-layer material is then sintered. Since organic solvents are not used, the risks to health and the risk of fire are considerably reduced. Furthermore, the composite materials produced according to the invention have exceptional resistance to cavitation. In addition to conventional fields of application relative to lubrication-free articles, such as bearings, these composite materials can therefore also be used in gear pumps and shock absorbers.
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.
