The invention provides a lubricant composition for hot metal working comprising a plurality of glass frits respectively having different softening point from each other.
摘要:
The present invention addresses the problem of providing an aqueous coating agent composition (in particular, an aqueous lubricating film paint composition that includes a solid lubricant) that suppresses the interaction of a curable resin and a surfactant, suppresses thickening/disproportionation throughout an aqueous coating agent, has superior overall fluidity, coating properties, and storage stability, and can form a favorable coating film, along with the problem of providing a member provided with said coating film, as well as a method for forming said coating film. Said problems can be solved by an aqueous coating agent composition that includes (A) a curable resin in the form of an aqueous emulsion, (B) a surfactant, (C) solid particles, (D) one or more nitrogen-containing heterocyclic compounds, and (E) water. In particular, the component (C) preferably includes a solid lubricant, and for reasons of environmental regulations, it is particularly preferable that the component (D) be 1,3-dimethyl-2-imidazolidinone.
摘要:
The invention relates to a machine part comprising a first physical component, wherein: the first physical component is configured for moving relative to a second physical component; the first physical component has a first surface with a contact area for physical contact with the second physical component; the first physical component is shaped spatially complementarity to the second physical component at the contact area, and a polyelectrolyte layer is present on the first surface at a location of the contact area. The invention further relates to a machine comprising the present machine part and the second physical component. In addition, the invention relates to the use of a polyelectrolyte layer to reduce the friction between the first physical component and the second physical component, and a rolling-elements bearing.
摘要:
A composition for solid coating formation, includes a composition made by containing, in a mixed solvent including water and a dipolar aprotic solvent, a powdery organic resin which is partially soluble at least in the dipolar aprotic solvent. The powdery organic resin is present in a state of being dissolved or dispersed in the mixed solvent.
摘要:
The present invention makes the insertion perception during actual surgery to be equivalent to the insertion perception of a catheter into a blood vessel model when water is used as the circulating fluid. A lubricant regulating fluid primarily composed of water is mixed with an aqueous metal salt and a surfactant as a lubricant regulating agent of the lubricant regulating fluid. A cationic surfactant, an anionic surfactant, a nonionic surfactant, or a dipolar ionic surfactant may be used as the surfactant. Also, the metal salt may be an alkaline metal salt, an alkaline earth metal salt, an aluminum salt, a ferric salt, or the like. In an example, the lubricant regulating fluid obtained by mixing an aqueous metal salt with water is prepared, and the lubrication and non-adherent properties of a catheter into a simulated blood vessel model are improved.
