Description
Przedmiotem wynalazku jest niepalny plyn o duzej lepkosci i smarnosci, stosowany w urzadzeniach hydraulicznych.The subject of the invention is a non-flammable liquid of high viscosity and lubricity used in devices hydraulic.
Obecnie do napelniania ukladów hydrauliki silowej dla pieców elektrycznych i wytlaczarek stosuje sie oleje hydrauliczne pochodzenia mineralnego i otrzymuje sie je z przerobu ropy naftowej. Wada tych produktów jest ich palnosc. Stwarza to niebezpieczenstwo powstawania pozarów lub eksplozji, szczególnie w urzadzeniach pracujacych przy otwartym ogniu. W celu usuniecia tych trudnosci podejmuje sie próby zastosowania w miejsce olejów hydraulicznych otrzymywanych z przerobu ropy naftowej, niepalnych plynów hydraulicznych, sporza¬ dzanych na bazie olejów samoemulgujacych, glikoli etylenowych, glikoli propylenowych, wody z dodatkami przeciwutleniajacymi, przeciwkorozyjnymi i przeciwrdzewnymi. Plyny te, mimo szeregu zalet takich jak: niepalnosc, stabilnosc, wlasciwosci antykorozyjne, nieagresywnosc w stosunku do uszczelnien, niska temperatura krzepniecia - nie znajduja zastosowania w tych ukladach hydrauliki silowej, które dotychczas pracowaly na oleju mineralnym o lepkosci 25-35 cSt w temperaturze 50°C l temperaturze krzepniecia ponizej -25°C, ze wzgledu na male zdolnosci smarne i niska lepkosc w temperaturze 50°C. Azeby mozna je bylo stosowac w ukladach hydrauliki silowej dla pieców elektrycznych i wytlaczarek - powinny posiadac zdolnosci smarne w mozliwie duzym zakresie temperatur, to znaczy, ze lepkosc ich powinna byc malo zalezna od temperatury.Currently, it is used to fill power hydraulics systems for electric furnaces and extruders hydraulic oils of mineral origin and obtained from the processing of crude oil. The disadvantage of these products is their flammability. This presents a risk of fires and explosions, especially in appliances working by open fire. In order to remove these difficulties, attempts are made to apply it in place hydraulic oils obtained from the processing of crude oil, non-flammable hydraulic fluids, based on self-emulsifying oils, ethylene glycols, propylene glycols, water with additives antioxidant, anti-corrosive and anti-rust. These fluids, despite a number of advantages such as: non-combustibility, stability, anti-corrosive properties, non-aggressive towards seals, low temperature solidification - they are not used in those power hydraulics systems that have so far worked on mineral oil with a viscosity of 25-35 cSt at 50 ° C and a pour point below -25 ° C, that due to low lubricating ability and low viscosity at 50 ° C. So that they could be used in power hydraulics systems for electric furnaces and extruders - should have lubricating abilities in the largest possible temperature range, that is, their viscosity should be little dependent on the temperature.
Celem wynalazku' bylo uzyskanie plynów hydraulicznych dla ukladów hydrauliki silowej o wysokiej lepkosc- idobsej smarnosci, które pozwolilyby na zastapienie stosowanych dotychczas olejów mineralnych c lepko ci 2S-35 cST w temperaturze 50°C a jednoczesnie byly niepalne. Cel ten osiagnieto w rozwiazaniu wedlug wynalazku. Nieoczekiwanie stwierdzono, ze dodatek poliglikolu etylenowego o ciezarze czasteczkowym 17000—26000 i temperaturze krzepniecia 60°C pozwala na uzyskanie plynu o smarnosci w duzym zakresie temperatur i minimalnej zmianie lepkosci wraz z temperatura.The aim of the invention was to obtain hydraulic fluids for high-pressure hydraulic systems viscosity- and persistent lubricity, which would allow the replacement of previously used mineral oils c 2S-35 cST viscosity at 50 ° C and were non-flammable at the same time. This goal was achieved in the solution according to the invention. Surprisingly it was found that the addition of polyethylene glycol with a molecular weight 17,000-26,000 and a freezing point of 60 ° C allows to obtain a fluid with a lubricity in a large range temperature and minimal viscosity change with temperature.
Plyn hydrauliczny wedlug wynalazku sklada sie z: —15 czesci wagowych poliglikoli etylenowych o ciezarze czasteczkowym 17000 —26000 i temperaturze krzepniecia 60°C,2 100 211 -50 czesci wagowych glikolu etylenowego i/lub 8-60 czesci wekowych glikolu propylenowego, glikolu dwupropylenowego, gl skolu trójpropylenowego, - 40 czesci wagowych wody zdemineralizowanej i i 0,5 - 2 czesci wagowych powszechnie stosowanych srodków antykorozyjnych, antyutleniajacych i przeciwrdzewnych.The hydraulic fluid according to the invention consists of: —15 parts by weight of polyethylene glycols with a molecular weight of 17,000 - 26,000 and temperature solidification 60 ° C, 2 100 211 -50 parts by weight of ethylene glycol and / or 8-60 parts by weight of propylene glycol, glycol di-propylene, g / tri-propylene, - 40 parts by weight of demineralized water and 0.5 - 2 parts by weight commonly used anti-corrosion, anti-oxidation and anti-rust agents.
Plyny o takim skladzie sa niepalne, o lepkosci 25-35 cSt w temperaturze 50°C, przy czym lepkosc ta niewiele zmienia sie wraz z temperatura, posiadaja dobra smarnosc w duzym zakresie temperatur, nie koroduja urzadzen hydraulicznych, nie speczniaja uszczelnien gumowych, teflonowych, winylowych itp.Liquids of this composition are non-flammable, with a viscosity of 25-35 cSt at 50 ° C, and the viscosity It does not change much with temperature, has good lubricity in a wide temperature range, does not corrode hydraulic devices, do not deteriorate rubber, Teflon, vinyl seals, etc.
