摘要:
The viscosity of liquid organic systems is increased by adding thereto an organophilic clay gellant which is the reaction product of a smectite clay having a cation exchange capacity of at least 0.75 milliequivalents per gram and from 1.00 to less than 1.20 milliequivalents per gram of clay of a methyl benzyl dialkyl ammonium salt, wherein the two alkyl groups independently contain from 16 to 18 carbon atoms, and from 0% to 1% water in the absence of a polar organic dispersant for the gellant.
摘要:
A semi-synthetic lubricant for high temperature applications, particularly adapted for use on relatively movable metallic surfaces during the shearing of molten glass, and consisting of an aqueous solution of a formulation comprising a non-drying vegetable oil, such as coconut oil, alkanolamine, the phosphate ester of an ethylene oxide adduct of a linear primary alcohol, an emulsifier, preferably the ethoxylated sorbitol hexaoleate, the fatty nitrogen derivative of distilled coconut oil primary amine, and a wetting agent. The wetting agent is preferably the methyl ester of a 50:50 mixture of methyl palmitate and methyl oleate.
摘要:
A surface treatment composition for metal working comprising 10 to 50 parts by weight of a water-soluble thermoplastic synthetic resin having an average degree of polymerization of 300 to 1,700, 40 to 180 parts by weight of an aqueous dispersion of an alkaline earth metal soap and 0.5 to 12 parts by weight of at least one volatile corrosion inhibitor, which can give to a metal panel excellent deep drawing processability, chemical treatment property, rust corrosion resistance or the like.
摘要:
A substantially neutral aqueous lubricant comprising a major portion of water, a polyelectrolyte acrylate compound, a fatty acid compound, a polyalkyleneoxide compound and a C.sub.1-6 alcohol, methods to make the lubricant and methods of its use.
摘要:
A coating consisting essentially of 0.5% to 50%, preferably 2% to 20%, by volume, polyethylene oxide and about 6% to 30% a dispersion agent selected from the group consisting of propylene glycol, glycerol, ethylene glycol, polypropylene glycol, diethylene glycol, triethylene glycol and hexylene glycol, with the ratio of polyethylene oxide-to-dispersion agent, by volume, being no greater than 2:1 and preferably 1:3. The remainder being essentially water. The coating is useful as a lubricant to facilitate pulling plastic-sheathed cable through a conduit, drawing wire through a die and mounting a tire on a rim. The coating is an emollient for wood and useful in metalworking to inhibit or otherwise control oxidation, and as an annealing and normalizing agent.
摘要:
An alcohol water solution of poly(ethylene oxide) having a molecular weight of about 4 million makes an extremely effective lubricant for applying to wire or cables which are to be pulled through conduits or raceways.
摘要:
The pasty damping medium is used to damp mechanical and/or acoustic osciallations. The agent contains as a minimum compound a solid finely divided substance or a mixture of solid finely divided substances, as a liquid phase, a silicone oil, a polyglycol, a mineral oil and/or a saturated aliphatic or aromatic aliphatic carboxylic acid ester, an agent for increasing the interfacial surface activity or a surfactant, a finely divided magnesium and/or aluminium silicate and/or a silicon dioxide finely divided as a viscosity stabilizer and possibly a small quantity of an antioxidant. The invention concerns also a method for producing the pasty damping medium and the use of the pasty damping medium in different hydraulic damping devices or for industrial shock absorber or industrial vibration damper.
摘要:
Lubricating compositions are disclosed which comprise a major amount of an oil of lubricating viscosity, thickened to a grease consistency with an oil thickener and a minor amount of a rare earth halide.
摘要:
The present invention relates to a paste-like damping medium for damping mechanical and/or acoustical vibrations, based on silicone oil, polyglycol, mineral oil and/or a thermally-stable aliphatic or aromatic carboxylic acid ester, finely divided solid material, an agent for reducing the surface tension and an agent for increasing the intrinsic viscosity.
