Abstract:
Herein disclosed is a dry type continuous wire drawing process which can retain satisfactory working circumstances while eliminating the problem of disposal of waste liquids. The wire drawing process includes the steps of descaling a wire to be drawn, coating the descaled wire with a lubricant, and drawing the lubricant-coated wire through a drawing die. The descaling step is conducted in a mechanical manner. At the lubricant coating step, the descaled wire is once coated with lime powder and then with metallic soap powder. Thus. the three steps recited are conducted under dry and continuous conditions. At the lubricant coating step, the lime-coated wire may be coated with powder of sodium stearate before it is coated with the metallic soap.

Abstract:
A novel lubricating grease that is useful for underwater applications is made up of lubricating oil that contains a co-polymer of a hydrocarbon backbone for promoting good adhesion and a fluorine containing backbone for promoting lubricity. The grease formulation is resistant to water washout and does not off-gas toxic compounds. In addition to the lubricating oil, the grease formulation includes fumed silica, and may contain one or more corrosion inhibitors, an extreme pressure filler such as boron nitride, and optionally one or more polyurethane initiators.
Abstract:
The invention relates to the production of materials which can be used in lubricating compositions for treating friction assemblies and also for restoring the friction surfaces of mechanism and machine parts.The composition is produced from the products of dehydration of natural and/or synthesized hydrates and/or mixtures thereof at an inherent water removal temperature and dehydration product stabilization temperature of 300-1200° C.The composition contains oxides from the series MgO and/or SiO2 and/or Al2O3 and/or CaO and/or Fe2O3 and/or K2O and/or Na2O and is a garnet-shaped conglomerate consisting of a nanograin and an amorphous binding phase.The size of the conglomerate is in a range of 100-100000 nm and the size of the nanograin is in a range of 2-2000 nm.The claimed method includes a step for stabilizing the dehydration product at a temperature of 900-1200° C. for a period of 1-3 hours, which makes it possible to form a stable conglomerate structure.
