摘要:
The invention relates to a shaping method wherein a material (10) of a workpiece (12, 30) is shaped using at least one mold (14, 44, 48, 50, 142). In order to allow a wider variety of shapes while enhancing quality, a lubricant (18) is used between the material (10) and the at least one mold (14, 44, 48, 50, 142), the viscosity of said lubricant being variable by applying or varying a field (56).
摘要:
A lubricating oil composition comprising: (a) a base oil selected from Group III base oils, polyalphaolefins, and mixtures thereof; (b) 0.3 wt% or less of sulphur; and (c) 30 wt% or less of viscosity modifier;
wherein the lubricating oil composition has a kinematic viscosity at 40°C in the range of from 2 mm 2 /s to 220 mm 2 /s and wherein the lubricating oil composition provides a weld load of 150 Kg or greater in the 4 ball weld load test (ASTM D2596). The lubricating oil composition of the present invention provides improved anti-wear and improved extreme-pressure properties.
摘要:
Concentrates for lubricating oil compositions are prepared by mixing at elevated temperature: (i) at least one high molecular weight ashless dispersant; (ii) at least one oil-soluble overbased metal detergent; and (iii) at least one other concentrate additive provided that the additive is first mixed with the detergent or the dispersant.
摘要:
Die Erfindung betrifft eine Dichtung, insbesondere verwendbar als Hochtemperaturdichtung, umfassend ein Dichtelement aus einem porösen Material, welches wenigstens teilweise mit einem Wirkstoff getränkt ist. Eine hohe Temperaturstabilität und ein sehr gutes Dichtverhalten wird dadurch erzielt, dass der Wirkstoff eine ionische Flüssigkeit umfasst.

摘要:
The present invention provides a lubricating base oil characterized by comprising saturated components of 90 % by mass or greater, wherein the proportion of cyclic saturated components among the saturated components is not greater than 40 % by mass, and by having a viscosity index of 110 or higher and an iodine value of 2.5. The lubricating base oil of the invention exhibits excellent viscosity-temperature characteristics and heat and oxidation stability while also allowing additives to exhibit a higher level of function when additives are included. The lubricating base oil of the invention is suitable for use in various lubricating oil fields, and is especially useful for reducing energy loss and achieving energy savings in devices in which the lubricating base oil is applied.
