Description
X a hr b e r o ich e#U 1 o Schmüeröle, deren Viecceitäteeigeneahaften die Anforderungen mehrerer UB-Klannen erMIleng worden ale gehrbereichvöle gekennzeichnet. Sie werden insbeaondere dort gewünscht, wo Xuschinen unter stark woob»lMen klimatischen Bedingungen arbeitene oder wo ein Winter- und Somerbetrieb ohne 4echsel den Schulerölen ermöglicht worden noll. X a hr be r o ich e # U 1 o lubricating oils, the quality of which is peculiar to the requirements of several UB clusters, have been labeled as all hearing areas. They are particularly desired where Xuschinen works under extremely poor climatic conditions or where winter and summer operations can be made possible without changing the school oil.
Die üblichen Mehrberolohedle werden aus niedrigvieconen, vorwiegend paraffinbaeischen Minaralblen aufgebaut, die den Eigenschaften der niedrigen VI,3-conitäteklasse (z.B. 10 W) entsprechen. Ihre Mehrbereichseigenschaften erhalten diese Öle durch Zusätze hochpolymerer Stoffe, wie PolyacrylaäureQster oder Polyolefine, die auf dao Öl bei höheren, nicht aber bei tiefen TemDeraturen vordickend wirken. »adurch wird auch das Viscoeitäte-Temperaturverhalten (Visconität13index) verbessert.The usual Mehrberolo nobles are made up of low-viecon, mainly paraffin-like minaralbels, which correspond to the properties of the low VI, 3-conity class (eg 10 W). These oils get their multigrade properties from the addition of high-polymer substances such as polyacrylic acid esters or polyolefins, which have a thickening effect on the oil at higher, but not at low temperatures. »This also improves the viscosity device temperature behavior (Visconity13index).
Nachteilig ist hierbei vor allem das ungünstige Verdampfungsverhalten des niedrigvisconen Grundöles, sowie das durch Paraffinausacheidungen verursachte ungünstige Kälteverhalten. Naphthenbaeische Öle haben zwar einen tiefen Stockpunkt und zeigen ke.Line Paraffinausacheidung. Ihr Viecositäta'--Temperaturverhalten Ist jedoch unzureichend und im Vergleich zu paraffinischen Ölen gleicher Viscaeität in Ihren Verdampfungsverhalten ungünetig. Auch sind die notwendigen hoben zuaUxe an Polymeren Verdickern bei starker thermischer und 8ob-erbtanspruchung, wie ei* z.B. in Diesolzotor auftreten" wenig stabil. Ihr Zerfall führt am Verlunt der gewünschten Viaoositätseigenschatten nowie häufig zu Ablagerungou und dami,+. zu Störungen in Betrieb.The main disadvantage here is the unfavorable evaporation behavior of the low-viscosity base oil, as well as the unfavorable low-temperature behavior caused by paraffin build-up. Naphthenic oils have a low pour point and do not show any paraffin build-up. However, their temperature behavior is inadequate and their evaporation behavior is unsuitable in comparison to paraffinic oils of the same viscosity. The necessary raised zuaUxe of polymers thickeners at strong thermal and 8ob-erbtanspruchung as ei * eg "occur less stable in Diesolzotor. Your decay leads on Verlunt the desired Viaoositätseigenschatten Nowie often Ablagerungou and dami, +. To disturbances in operation.
Es wurde gefunden, daß aLan vorzügliche Mehrbereichedleg die die erwähnten Naohteile nicht aufweisen@ erhält# wenn man paraffinbasiechen ölen, vorzugeweine solchen, die vom Hauptanteil ihren krietallisierenden Paraffingehulten -befreit sind, ein Gemisch aus öligen Diestern einer Monadecandiaäure und öligen Diestern der Dodeaandiaäure, oder Gemische eines dieser Esteröle oder den Esterölgezieches mit einem naphthenbaalechen Minerslöl zusetzt, Dieser Zusatz ermöglicht es, paraffinbasiaohe Öle mit höherer Visoosität und damit günstigem Verdampfungeverhalten zu verwenden und gleichzeitig deren ungtnat:Lge Kälteeigenachaften zu verbessern.It has been found that excellent multi-range edlegs that do not have the aforementioned Naohteile @ obtained when you oil paraffin-based, especially those that are freed from the main portion of their crystallizing paraffin-free, a mixture of oily diesters of a monadecanedic acid and oily diesters of dodeaanediaic acid, or mixtures one of these ester oils or the ester oil goats with a naphthenic mineral oil is added. This additive makes it possible to use paraffin-based oils with a higher viscosity and thus favorable evaporation behavior and at the same time to improve their inappropriately cold properties.
