“Ho silafala ha varnish ke bothata bo atileng lioling tse ngata tsa turbine ea khase.Na mofuta ona oa tšilafalo o na le litšobotsi tsa polar?Ho na le lipampiri tse ngata tse buang ka tšilafalo ea varnish, lisosa tsa eona le litlhare.Boholo ba lipampiri tsena, thepa ea polar ea litaba tsa varnish e amohetsoe e le 'nete e netefalitsoeng, empa lipatlisiso le liteko tsa rona ha li tšehetse sena.Maikutlo a hau ke afe tabeng ee?
Ka kakaretso, varnish e tsejoa e na le thepa ea polar.Leha ho le joalo, e ka ba le likarolo tse seng tsa polar.Varnish ha e bonolo ho e hlalosa hobane ha ho na mofuta o le mong.Lintho tse ngata li ama mofuta oa varnish e hlahang, ho kenyelletsa le maemo a ts'ebetso, mofuta oa oli le tikoloho.
Ho e-na le ho leka ho beha li-parameter tse itseng holim'a thepa ea varnish, ka tlase ke lethathamo la lintho tse 10 tse lokelang ho utloisisoa ka varnish kaha e sebetsa ho lubrication.
1. Sebopeho sa li-varnish se ka qala ho tloha ho oxidation le polymerization ea lubricant le maro a mang kapa khatello e bakoang ke khatello ea mocheso le diesel.Setšoantšo se ka tlase se bontša mekhoa e ka sehloohong ea ho etsa li-varnish.Le hoja ho na le lisosa tse ling tse ngata tsa varnish, tsena ke tsona tse hlokomelehang ka ho fetisisa.
2. Varnish hangata ke submicron ka boholo 'me haholo-holo e na le adherent oxide kapa carbonaceous lintho tse bonahalang.Likarolo tsa eona li ka nkuoa ho tsoa ho metsoako ea thermo-oxidative ea limolek'hule tsa oli ea mantlha le li-additives hammoho le ho roala tšepe le litšila tse kang litšila le mongobo.Liphetoho tsa cyclic lipakeng tsa ho futhumatsa le ho pholisa li pepesetsa oli ho senyeha ha mocheso le oxidation.
3. Ho thehoa ha li-varnish le li-sludge ho bakoa ke pula ea li-high-molecular-weight insoluble oxides ho tloha oli.Joalo ka lintho tsa polar, li-oxide tsena li na le ho qhibiliha ho fokolang ho oli e seng ea polar joalo ka oli ea turbine.
4. Sena se etsa filimi e tšesaane, e sa tsitsang e koahelang bokahare ba likarolo tsa mochine 'me e baka ho khomarela le ho se sebetse ha likarolo tse tsamaeang tse haufi-ufi joaloka li-valve tsa servo.
5. Ponahalo ea varnish ka likarolo tsa mochine oa ka hare e ka fetoha ho tloha ho 'mala o mosehla ho ea ho lintho tse lefifi tse kang lacquer.
6. Varnish e ka boela ea bakoa ke li-bubble tsa moea tse kentsoeng tlas'a khatello ea adiabatic libakeng tsa mojaro.Li-bubble tsena tsa moea li hatelloa ka potlako, tse lebisang ho bola ha oli le li-additives.
7. Nakong ea mekhahlelo ea pele ea oxidation le ho thehoa ha lihlahisoa tsa oxidation, lihlopha tsa motheo tsa Sehlopha sa II li hanyetsa haholoanyane.Leha ho le joalo, joalo ka ha lihlahisoa tse ngata tsa oxidation li theha, li-stocks tsena li ka hlaseloa habonolo ke litaba tsa varnish ka lebaka la boemo ba tsona bo phahameng ba polarity.
8. Maemo a ts'ebetso joalo ka libaka tse fapaneng tsa khatello e phahameng, nako e telele ea ho lula le litšila tse kang metsi li ka khothaletsa oxidation.
9. Ntle le ho fifala ha oli, bokhoni ba li-varnish bo ka shejoa ka mahlo ka ho lemoha masala leha e le afe, sekontiri sa tar kapa gummy-joaloka likhalase tsa mahlo, lisebelisoa tsa mochine oa ka hare, lisebelisoa tsa filthara le li-separators tsa centrifugal.
10. Bokhoni ba varnish bo ka boela ba shejoa ka tlhahlobo ea oli ho sebelisoa spectroscopy ea Fourier transform infrared (FTIR), ultracentrifuge, colorimetric analysis, gravimetric analysis le membrane patch colorimetry (MPC).
