Shenhai Ho phatloha-Bopaki
Lits'ebetsong tsa motlakase tse thibelang ho phatloha, lisebelisoa tsa ho kenya letsoho li arotsoe ka mefuta e tiileng le ea metsi, e etselitsoeng likopo tsena ka ho khetheha, ho fapana le mekhahlelo e pharaletseng ea ho kenya letsoho.
Lisebelisoa tse tiileng tsa Insulation
Ho thoeng ke “thepa ea ho tiisa boemo bo tiileng,” tsena ke lintho tse lulang li tiile tlas'a maemo a ts'ebetso. Sehlopha sena se kenyelletsa lisebelisoa tse kang li-varnish tsa insulating, tseo qalong di leng metsi empa di tiile ha di sebetsa.
Lisebelisoa tse tiileng tse sebelisoang ka mokhoa o tiileng lisebelisoa tsa motlakase tse thibelang ho phatloha li thathamisitsoe ka tlase.

Lisebelisoa tsena li hlophisoa ho latela Index ea tsona ea Comparative Tracking (CTI), tekanyo ea tšebetso ea motlakase e ka holimo. Leha ho le joalo, mechine ea bona, mocheso, le thepa ea lik'hemik'hale e ka fapana haholo, e hlokang kgetho e hlokolosi e itshetlehileng hodima maemo a itseng a tikoloho a tshebediso, ho kenyelletsa le ho nahana ka matla a mochini, ho hanyetsa mocheso, le ho tšoarella ha lik'hemik'hale.
Ceramic (E kganyang) Lisebelisoa
E kenyelletsa lintho tse sa sebeliseng tšepe tsa inorganic insulation, tsena li entsoe ka li-oxide tsa tšepe tse sintering le metsoako ea tšepe e seng ea oksijene. Litšobotsi tsa bona li kenyelletsa mofuta oa boima ba 1000 ~ 5000HV, matla a matla ho tloha 26 ~ 36 MPa, matla a hatellang ho tloha ho 460 ~ 680 MPa, libaka tse qhibilihang tse fetang 2000°C, katoloso e tlase ea mocheso, le botsitso bo phahameng ba lik'hemik'hale le ho hanyetsa ho bola.
Polytetrafluoroethylene (PTFE)
Thepa ena ea fluoroplastic e boloka tšebeliso ea nako e telele ho mocheso ho tloha -180 ° C ho isa 260 ° C.. E tsitsitse haholo ka lik'hemik'hale, e hanyetsanang le ho bola, e bonts'a coefficient e tlase ea likhohlano, 'me e na le coefficient ea bohlokoa ea katoloso ea mocheso.
Phenolic Plastiki
Plastiki ea thermosetting, tse tsejoang ka khoebo ka “bakelite” kapa “phenolic board,” e khona ho mamella mocheso o fetang 3000 ° C mme e fana ka khanyetso e ntle haholo ea ho cha le botsitso ba lik'hemik'hale, le hoja e brittle ebile e sa hanyetse ho bola ha alkali.
Ho phaella ho lisebelisoa tse tiileng tsa ho koala tse boletsoeng, lisebelisoa tsa motlakase tse thibelang ho phatloha li sebelisa haholo lintho tse fapaneng tse tiileng tse thibelang ho phatloha, ho kenyelletsa le lisebelisoa tsa polasetiki bakeng sa likarolo tsa insulating le lisebelisoa tse ling tse thusang tse ka har'a li-motor tse thibelang ho phatloha.
Lisebelisoa tsa Insulation tsa Metsi
Tsena li bua ka lintho tse sireletsang metsi tse fumanehang ka mokhoa oa mokelikeli, joalo ka oli ea transformer, le lisebelisoa tse kang varnish e sireletsang e sebelisetsoang ho kenya li-coil, tse tiileng ka mor'a liphekolo tse khethehileng empa li ntse li nkoa e le li-insulator tsa metsi.
1. Oli ea Transformer
• Bohlokoa bakeng sa lisebelisoa tsa motlakase tse sa phatloheng tse kang li-transformer, oli ena e lokela ho finyella litekanyetso tse itseng:
• Sebaka sa ho tima ha se ka tlase ho 300°C.
• Sebaka sa ho benya ha se ka tlase ho 200°C (komiki e koetsoeng).
• Kinematic viscosity e sa feteng 1*10?? m²/s ho 25°C.
• Matla a ho senya ka dielectric bonyane 27kV.
• Ho hanyetsa molumo bonyane 1*10??? m ka 25°C.
• Tšela ntlha e seng ka holimo ho -30°C.
• Acidity (boleng ba neutralization) ho fihlela 0.03 mg/g (potassium hydroxide).
Oli ea Transformer, haholo-holo oli e thibelang liminerale e nang le alkanes, li-cycloalkanes, le li-hydrocarbon tse nkhang hamonate tse sa tsitsang, e fana ka litšoaneleho tse babatsehang tsa ho itšireletsa le botsitso ba botsofali. Leha ho le joalo, Tšebeliso ea eona ho thepa ea merafo ea Sehlopha sa I e thibetsoe ka lebaka la ho senyeha ho ka bang teng ha thepa ea eona ea ho itšireletsa ka lebaka la tšebeliso ea nako e telele..
2. Varnish
E sebelisetsoa ho kenya likhoele tsa motlakase ka har'a lisebelisoa tse thibelang ho phatloha, ho kenya li-varnish ho ntlafatsa bokhoni ba bona ba ho kenya motlakase. E fumaneha ka mefuta e thehiloeng ho solvent le e se nang solvent, li-varnish tsena li entsoe ka li-resin tsa tlhaho kapa tsa maiketsetso tse kopantsoeng le metsoako e fapaneng e kang benzene le alcohols bakeng sa mofuta o thehiloeng ho solvent., le li-resin tsa maiketsetso, liente tse tiisang, le li-thinner tse sebetsang tse kang styrene bakeng sa mofuta o se nang solvent.
Mefuta ka bobeli ea varnish e fana ka likhetho tse ngata ho lumellana le litlhoko tse fapaneng tsa kopo, ho netefatsa ho ikamahanya le maemo ho latela litlhoko tse khethehileng tsa ts'ebetso.
