摘要:
The present invention provides an anti-seizure agent for hot steel working comprising: an inorganic component as a first component; sodium hydroxide as a second component; water-soluble resins and/or water-soluble surfactants as a third component; and water, wherein, to the mass of the sum of the first component, the second component, and the third component as 100 mass %, the anti-seizure agent contains: 96.5 mass % or more and 99.98 mass % or less of the first component; 0.01 mass % or more and 2. 0 mass % or less of the second component; and 0.01 mass % or more and 1.5 mass % or less of the third component, and the inorganic component is one or more selected from a group consisting of Al 2 O 3 , SiO 2 , CaO, B 2 O 3 , K 2 O, and Na 2 O. This anti-seizure agent for hot steel working exhibits excellent wettability and surface firm-adherability to the steel; moreover, the coating layer formed after application solidly adheres to the steel and does not come off in the environment of both cold and hot working.

Described are stable aqueous polyolefin-wax dispersions containing: A) 5 to 65 % by wt. of polyethylene or polypropylene wax with an average particle size of 1 to 50 νm and an acid number of less than 5 mg KOH/g of wax and, as dispersant; B) 0.5 to 20 % by wt. of the reaction product of 1 to 50 mol of a 1,2-alkylene oxide with 2 to 4 C-atoms, and a glyceride of unsaturated C16-C22 monocarboxylic acids with one or more primarily ethylenic unsaturated bonds and which may also contain hydroxy groups. These dispersions are suitable for use in the manufacture of floor- and stonework-care agents, shoe-care agents, car-care agents, printing inks, printing pastes, paints, packaging, lubricating grease, vaseline, drawing agents, sealing and insulating compounds for electrical components, aqueous wood glazes, hot-melt coatings, cosmetic preparations and toothpaste, in the plastics-processing industry, in paper manufacturing and in corrosion protection, in the finishing of yarns and fabrics, in treating leather and as mould-release agents in the chill-casting, die-casting and centrifugal casting of non-ferrous metals.

摘要:
In one aspect the invention is a carrier-free pulverulent metalworking lubricant containing a resin having a highly polar functional group, and in another aspect is a method of the invention of forging a workpiece in a die which includes the step of applying to at least one of the die and the workpiece a coating of an effective amount of the carrier-free pulverulent lubricant composition. The use of the composition and method of the invention significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.
摘要:
