WATER-SOLUBLE OR DISPERSE-CASH PP.
Form of its salts wasserl6sliches or - dispersable PP, containing units, which yon a Polyoxyalkylendiamin - Homopolymer or - copolymer come, as well as on a schmierfiihige wiissrige Arbeitsfliissigkeitszusammensetzung (e.g. metalworking Fliissigkeit), which such a PP enthiilt.
Niehtwfissrige Arbeitsfliissigkeiten and Arbeitsfliissigkeiten on w of issriger basis find vielffiltige Anwendungsm Sglichkeiten, for example as hydraulic Fliissigkeiten, metalworking Flfissigkeiten, WgrmeiibertragungsFliissigkeiten, electronic Kiihlmittel, Diimpfungsfliissigkeiten and SchmiermitteI. In order to become fair this different Anwendungsm6glichkeiten, Arbeitsfliissigkeiten are adapted hfiufig to the characteristics nnd achievement characteristics, which are ssigkeit ffir the intended use of the flat steel bars spezifiseh. To the main operational areas yon Arbeitsfliissigkeiten geh6ren their use as hydraulic Fliissigkeiten and metalworking Fliissigkeiten. During metalworking they are used with boring, thread cutting, pulling, tricks, Friisen, Rumen, loops, Biegem rollers and fihnlichen Metallbearbeitungsvorgiingen. The Stabilitiit and the Sehmiereigenschaften of the Arbeitsfliissigkeit as a whole as well as the individual components of the Flfissigkeit play a large role with the achievement and the usefulness of the Fltissigkeit with the hydraulisehen and application of metalworkings. A large Stabilit it the Fliissigkeit and its components w it-ends to the storage and the use as well as a large Schmierf ihigkeit the Fliissigkeit is important and worthwhile Eigensehaften when using the Fliissigkeit as hydraulic Flfissigkeit or Metallbearbeitungsfliissigkeit.
In the last years Arbeitsfltissigkeiten of aufwfisstiger basis at meaning won, anfgrund their advantages regarding landlord detention borrowingness, security, environment, removal and inflammability more gegeniiber nichtwfissrigen Arbeitsfltissigkeiten. These advantages are particularly betriichtlich in the Hinbliek up those great importance, which is dedicated gegenw irtig to security and the environment, in particular with Metallbearbeitungsvorgfingen. The wirtschafflichen advantages of the w issrigen Arbeitsfliissigkeiten more gegeniiber niehtw issrigen Arbeitsfliissigkeiten attained up those supply problems and the rising price of nichtwiissriger Arbeitsfliissigkeiten at meaning in the Hinbliek. So that these advantages w of ssriger Arbeitsfliissigkeiten men in addition, for carrying kom4s, such Flfissigkeiten should exhibit a high Stabilitfit w hrend the storage and the use, possess in the same way a high Schmierf ihigkeitsgrad. The w issrigen Arbeitsfliissigkeiten should thus very widerstandsfiihig against fibre of a separation in one or more components of the Gemisehs as well as resisted a unerwfinschten dismantling (e.g. decomposition) of the components of the Flfissigkeit to be dhig more gegeniiber, in particular a unerwiinschten dismantling of the lubricant component of the Flfissigkeit. The separation and the unerwiinschte dismantling of the components (insbesonss dere of the lubricant component), the wfissrigen Arbeitsfliissigkeit decreases the Effektivitiit and length of application of the Fliissigkeit, so that such unenviinschte effects arise like 1) a iiberm3ssiger wear of the metal construction units of the hydraulic system (e.g. pumps and valves) and animal metalworking mechanism (e.g. cutting tools, rollers and stamp), some 2) of the worked on metal products, which exhibit a sehleehte Oberfl iehen finishing and no correct dimensions. Although many wfissrige work vertic. stabil. ssigkeiten after the state of the art admit 6s are and during metalworking and used in hydraulic area harm and it is used to have this Fliissigkeiten Stabilitfitsund/or Schmierf higkeits654 of 582 problems raised, which fiihren to the fact that their effective employment is inkt or excluded beschr. The professional world has itself therefore stiindig with the further training of wiissriger Arbeitsflfissigkeiten beschiiftigt.
s task of the invention is it therefore to place the disadvantages of the w issrigen Arbeitsfliissigkeiten after the state of the art to tiberwinden and Yerbindungen to the Verffigung those as lubricant connection in stable schmierffihigem a wfissrigen work vertic. stabil. ssigkeit usable sind.
