摘要:

AbstractSynthetic base oil components include mainly polyalphaolefins (PAO), dicarboxylic acid esters and polyol esters. In 1977, the world‐wide share of synthetic oils was about 0.5% of lubricant sales; today this is about 2%, and further annual growth rates of between 10 and 20%—relative to present consumption levels—are expected. The motor vehicle share of the synthetic oil market is about 30%, with the trend rising. In recent years, the literature has contained numerous reports on the general advantages and disadvantages of carboxylic acid esters. This standard knowledge is not repeated here. A few special and relatively new aspects are discussed, based on work carried out at VEBA Öl AG and Chemische Werke H

摘要:

AbstractThe requirements of lubricating greases in the deep‐freezing industries, that lubricants do not undergo degradation of their lubricating properties, and the need for non‐aromatic and non‐toxic/non‐carcinogenic lubricants in food production, are discussed. Experimental data on the applicability of synthetic oils as bases for synthetic greases, are pr

摘要:

AbstractThe intention of this paper is to examine the relationship between the chemical structure of ester base fluids and their influence on elastomer seals and wear characteristics. It presents background information about esters, some of which can be considered as blending components for mineral oil and/or polyalphaolefins, while others have properties so similar to mineral oil that in principle substitution is possible. It examines the effects of ester base fluids on a number of properties of elastomers, including modulus, tensile strength, elongation at break, hardness, and volume changes. It also explains a method of selecting synthetic base fluids for performance upgrading or viscosity purposes, using a ‘non‐polarity index’ which allows more speedy comparison and selection of ester base f

摘要:

AbstractThis paper outlines some of the properties of various silicone products, such as thermal and oxidative stability, corrosion protection, and vapour pressure. It looks at the suitability of developed fluids in various applications, and provides basic data on the performance of certain silicone fluids in tests.
