摘要:
Stable concentrated liquid and solid antimicrobial lubricating compositions can be formulated which include (-) 5 to 40 wt % of a C.sub.6-24 fatty acid, (-) 10 to 40 wt % of a quaternary ammonium salt, (-) an amount of an alkaline source sufficient to increase the pH of the composition to at least 8, and optionally (-) about 0.1 to 10 wt % of an amine. The balance of the liquid form of the composition constitutes water. The lubricating compositions are particularly useful on the load bearing surfaces of conveyor belts used in food preparation where a combination of effective lubricity and efficacious antimicrobial activity are necessary.
摘要:
A lubricant to be sprayed onto the surface of a steel material for forming a lubricant coat on the surface of the steel material to be forged. The lubricant comprises a particulate lubricant composed of thermally melting resin mixed with inorganic lubricant. The particulate lubricant is applied onto the surface of a steel material to be forged. Before or after applying the particulate lubricant onto the surface of the steel material, the surface of the steel material is heated. Consequently, the thermally melting resin melts and coheres with the inorganic lubricant over the surface of the steel material, resulting in the formation of a uniformly thick lubricant coat over the steel material. The lubricant coat prevents the steel material from being burnt in a forging device even during hot forging. The lubricant coat is fit for the forging of hard to work steel material. The lubricant coat also contributes to the decrease in forging cost, without deteriorating the forging environment.

C. of from 10 to 1,000,000 cSt;(B) from 10 to 200 parts by weight of a filler comprising at least one member selected from the group consisting of calcium carbonate, zinc carbonate, a composite zinc white, and silica; and(C) from 0.001 to 0.1 part by weight of platinum or a platinum compound.
摘要:
Piston deposits resulting from neutralizing combustion acids present in the lubricating oil circulating within the lubrication system of an internal combustion engine are reduced or eliminated by first cntacting the acids with a soluble weak base in the piston ring zone of the engine to form soluble neutral salts containing the weak base and the combustion acids. Thereafter, the neutral salts are contacted with a heterogenous strong base immobilized within the lubrication system but outside of the piston ring zone. The strong base displaces the weak base from the neutral salts, returning the weak base to the oil for recirculation to the piston ring zone for further use. The remaining strong base/combustion adic salts are immobilized as deposits with the strong base rather than on the piston. In a preferred embodiment, trioctadecyl amine is the weak base and magnesium oxide is the strong base.
摘要:
Lubricating compositions for use with fiber optic elements and method for their preparation are claimed. Lubricating compositions are made from a mixture of polybutene and hydrophobic silica. The other ingredients such as oily polybutene, an amine phosphate, mineral oil, polytetrafluoroethylene, polyethylene are optional. Other materials such as coloring agents and antioxidants can be also used.
摘要:
A die-casting powdery mold releasing agent according to this invention is a mold releasing agent comprising a mixture of powdery or granulated mold releasing base material composed of an inorganic compound as used for lubricant in a solid form and an organic compound giving adhesive property to the mold releasing agent, the both having powdery or granulated configurations, or configurations in which the organic compound is covered on the mold releasing base material. The mold releasing agent allows production of castings of high quality, in the die-casting method with good workability and without worsening environmental situations.
摘要:
A lubricant comprising an oil-in-water emulsion and solid particles, in which the oil is a lubricating material and the oil droplets are stabilized by a surface coating of partially hydrophobic silica particles of a size less then 1 micrometer. This lubricant is to be used as a hydraulic fluid and as a metal-working or metal-rolling fluid.

An optical fiber cable incorporating either a lubricant or an antistatic agent or both in the outermost layer of the optical fiber unit; incorporating a lubricant or an antistatic agent or both in the pipe; and incorporating a lubricant or an antistatic agent or both in both the outermost layer of the optical fiber unit and the pipe.
摘要:
The present invention is, in one form, an aqueous alkaline metalworking fluid composition in the form of a concentrate which includes a salt of orthophosphoric acid; a dibasicdioic acid in an amount of up to about 5.0% by weight of the concentrate; an essentially phosphonate-free chelating agent; and, a neutralizing base. The composition may also include a lubricating agent, a coupling agent, a passavating agent, a biocide, and a colorant.
摘要:
A high performance lubricating grease effectively lubricates and greases front-wheel drive joints. The front-wheel drive grease has excellent extreme pressure properties and antiwear qualities and is economical, non-toxic and safe. In one preferred form, the front-wheel drive grease comprises a base oil, a thickener comprising polyurea and calcium complex soap, and an additive package comprising tricalcium phosphate and calcium carbonate.
