Abstract:
A grease composition for construction equipment comprises a lubricating grease, a) 1 to 5% by weight of phosphate glass and b) 1 to 5% by weight of a sulfur-phosphorus extreme-pressure additive; as well as c) 0.5 to 3% by weight of an aromatic sulfonic acid salt and d) 0.1 to 3% by weight of a triazole compound as optional components based on the total weight of the grease composition. The grease composition exhibits considerably high resistance to load and accordingly, can be applied to construction equipment which require high resistance to load, such as a hydrauric excavator and a wheel loader.
Abstract:
A solid lubricant composition comprises (I) 30 to 70 parts by weight of graphite, (II) 70 to 30 parts by weight of a mixture of at least two components selected from alkali molybdate, alkali or alkaline earth sulphate and alkali phosphate, the ratio of the two individual ingredients being in the range of from 0.05/1 to 20/1. Compositions give improved load-bearing capacity and allows settling of friction coefficient.
Abstract:
Agent for the pickling of and as an antioxidant for workpieces made of iron and steel in the case of when they are subjected to non-cutting, hot transformation. The agent is used in dry form. The agent contains: (a) 20 to 80 percent by weight of a pickling-effective compound, such as, sodium metaborate; (b) 1 to 80 percent by weight of a component, such as, graphite; and (c) zero to 79 percent by weight of at least one substance selected from group (d), (e) and/or (f). Zero to 35 percent by weight of group (d), such as, coke, can be used as substance (c) and, for example, act as antioxidants. Zero to 50 percent by weight of group (e), such as, sodium chloride, can be used as substance (c), and control the physical characteristics. Zero to 5 percent by weight of group (f), such as, ammonium chloride, can be used as substance (c) and, for example, act on the reduction of the oxides of group (a).
Abstract:
An improved lubricating oil composition comprising a major amount of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount by weight of at least one of certain co-polymers derived from the polymerization of (1) an N-vinyl-pyrrolidone, and (2) an oil-soluble acrylic ester.
Abstract:
PURPOSE:To provide the titled die lubricant which consists of phosphoric acid (salt), boric acid (salt), salt or hydroxide of alkali metal and laminar silicate in specified proportions and exhibits excellent lubricating and release properties. CONSTITUTION:A water-soluble glass (A) is prepared by mixing 14-50mol% (as P2O3) phosphoric acid (salt), 0-80mol% (as B2O3) boric acid (salt) and 30- 80mol [as M2O (M is alkali metal)] at least one compd. selected from among carbonate, nitrate, sulfate and hydroxide of alkali metal (e.g. Na2CO3) and melting the mixture followed by quenching. For applications where the lubricity is important, 91-99.5wt% (A) is mixed with 9-0.5 laminar silicate (B) (e.g. white mica) and for applications where importance is attached to the releasability 0.5-39wt% (A) is mixed with 99.5-61wt% (B).
Abstract:
A method for performing a coiled-tubing process, the method having the steps: performing a coiled-tubing process using a fluid-lubricant composition that includes a sulfur-containing compound, and introducing the fluid-lubricant composition into a subterranean wellbore casing.
