摘要:
Provided is a water-based lubricating coating agent from which a lubricating coating film which has excellent corrosion resistance, workability, and film removability in practical use is obtained. A water-based lubricating coating agent characterized in that a water-soluble silicate (A) and at least one water-soluble inorganic salt (B) selected from the group consisting of a tungstate, a phosphate and a borate are blended such that the solid content mass ratio (B)/(A) falls within the range of 0.7 to 25.

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von (Poly)harnstoffpulvern mittels Sprühtrocknung, neue (Poly)harnstoffpulver, sie enthaltende Zusammensetzungen sowie deren Verwendung als Verdickungsmittel, insbesondere in Schmierstoffen, wie sogenannten Polyharnstofffetten.
摘要:
A lubricating oil for plastic working contains a powder of a compound having a urea bond incorporated therein. The lubricating oil forms a thick lubricating coating having excellent thermal resistance and loading resistance on the frictional surface during working by simply applying it on the surface of a material or a mold and, therefore, effectively prevents occurrence of seizing, even in the production of moldings having a high degree of working or complex shapes. The plastic worked product has a coating of the lubricating oil on its surface which provides an excellent anticorrosive effect for steel stocks. The oil may also contain at least one extreme-pressure additive selected from: (1) condensed phosphoric acid, (2) phosphite and phosphate esters, (3) organic sulfur compounds, and (4) organic chlorine compounds. t
摘要:
Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides. The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCI) to form corrosive amine salts.

摘要:
This invention relates to novel water soluble metal working fluid compositions, their use to work metal, a process for working metal using such compositions and the metal worked article of manufacture. More particularly, this invention relates to fluid compositions useful in cutting, grinding, shaping and other metal working operations which require a lubricant. The terms "first Group A" and "second Group B" are used herein to denote different groups and not to indicate any sequence of use or selection as any possible combination or sequence of use of a component(s) is envisioned without limit of any kind. The disclosed fluid compositions are also anticorrosive and environmentally more acceptable than current oil based fluids. There has now been discovered an essentially odorless, substantially non-oil misting, water-soluble metal working fluid comprising, at least one component selected from a first Group A herein and optionally one or more components selected from a second Group B herein preferably with the balance of the composition being water and other (optional) minor ingredients. When a component is employed from Group A and a component is employed from Group B the action of the combination generally enhances performance of the resulting combination with contain moieties from both Group A and Group B.
