I-polyethylene ehlanganisiweI-insulation yenziwa ngezindlela zamakhemikhali noma zomzimba ukuze kuguqulwe i-molecule ye-polyethylene isuka ekwakhiweni kwamangqamuzana eqondile iye kwisakhiwo senethiwekhi esinezinhlangothi ezintathu, isuka ku-thermoplastic iye kwi-thermosetting material, nokwenyusa izinga lokushisa lisuka ku-70 ℃ liye ku-90 ℃, elithuthukisa kakhulu ukusebenza kwempahla. .
I-polyethylene ehlanganisiweinezinzuzo ezilandelayo.
1, Ukusebenza okuvimbele ukushisa;I-XLPE enokwakheka kwemeshi enezinhlangothi ezintathu inokusebenza okuhle kakhulu okumelana nokushisa.Ngeke ihlakazeke futhi i-carbonize ngaphansi kuka-200°C.
Izinga lokushisa elisebenza isikhathi eside lingafinyelela ku-90 ℃, kanti impilo eshisayo ingafinyelela eminyakeni engama-40.
I-2, Ukusebenza kwe-insulation: I-XLPE igcina izici ezinhle zokufakelwa kwe-PE, futhi ukumelana nokufakwa kwe-insulation kuyanda.I-dielectric yayo
Inani le-tangent ye-dielectric loss angle lincane kakhulu, futhi alithintwa kakhulu izinga lokushisa.
3, Izakhiwo zemishini: Ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecules, ubulukhuni, ukuqina, ukumelana nokugqoka kanye nokumelana nomthelela we-XLPE kuyathuthukiswa.
Ukuqina, ukuqina, ukumelana nemihuzuko kanye nokumelana nomthelela we-XLPE kuyathuthukiswa ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecules, ngaleyo ndlela kunxeshezelwe ukushiyeka kwe-PE eqhekezeka kalula ngenxa yokucindezeleka kwemvelo.
I-4, Ukumelana namakhemikhali: I-XLPE ine-asidi eqinile ne-alkali ukumelana nokumelana nowoyela, futhi imikhiqizo yayo evuthayo ingamanzi nesikhutha.
Ayinangozi kangako emvelweni futhi ihlangabezana nezidingo zokuphepha komlilo zanamuhla.
