Ikhebula lempilo ende yeminyaka engu-70ilungele zonke izindawo ezinabantu abaminyene, njengenxanxathela yezitolo, amathiyetha, iziteshi, izikhumulo zezindiza nezinye izindawo zomphakathi, kanye nemigqa yokusabalalisa ebalulekile, izintambo zokwakha, ukuhlobisa ikhaya, njll.
Impilo yesevisi yalo mkhiqizo ayikho ngaphansi kweminyaka engu-70 ezingeni lokushisa elijwayelekile elingu-70°C.Izinga lokushisa elivumelekile lokusebenza lesikhathi eside lekhondatha yekhebula ngu-90°C, 105°C, no-125°C;izinga lokushisa eliphezulu lokusebenza ngesikhathi sokujikeleza okufushane (isikhathi esiphezulu se-5S) ngu-250°C.
Isendlalelo se-cable insulation sithatha ukwakheka kwe-radiation cross-linked double-layer insulation.I-insulation yangaphakathi ihlangabezana nokusebenza kokufakwa kukagesi, okokufaka kwangaphandle kuhlangabezana nokusebenza kwe-flame retardant, futhi izendlalelo zangaphakathi nezingaphandle kanye kanye zihlangabezana nokusebenza okuphezulu kwempilo.
Izizathu nezinzuzo zokusebenzisa i-radiation cross-linking for insulation (uma kuqhathaniswa ne-PVC evamile): Impahla ye-PVC yendabuko ayinakusimama kahle kwe-thermal.
Iba lukhuni futhi ibe brittle emazingeni okushisa aphansi, futhi ithambe kalula futhi ikhululeke emazingeni okushisa aphezulu.Inokumelana nomthelela ongemuhle kanye nokumelana nokuguga, ikhipha kalula amagesi ayingozi emazingeni okushisa aphezulu, futhi yehlise kalula izinto eziyingozi phakathi nokukhiqizwa nokusetshenziswa, okubangela imiphumela emibi kubantu nasemvelweni.
I-radiation cross-linking isebenzisa imishayo yama-electron enamandla amakhulu akhiqizwe ama-accelerator ama-electron ukuguqula isakhiwo samangqamuzana sangempela esifana neketango sibe uhlaka lwamangqamuzana enethiwekhi enezinhlangothi ezintathu ukuze kwakheke izixhumanisi eziphambanayo.
Isakhiwo samangqamuzana enethiwekhi enezinhlangothi ezintathu sinokuzinza okuhle kwe-thermal, futhi ukufakwa kwe-insulation, ugesi kanye nemishini kuyathuthukiswa.Intuthuko enkulu.
Izinzuzo eziyinhloko zokusebenza zimi kanje
Impilo yekhebula ivunyelaniswa nesakhiwo: iminyaka engama-70.Ngenxa yezinga eliphezulu lokumelana nezinga lokushisa kanye nezinga lokushisa eliphezulu lokuguga le-irradiation cross-linked insulation, impilo yesevisi yekhebula ekhiqiza ukushisa ngesikhathi sokusetshenziswa iyanwetshwa.
Umthamo omkhulu wokuthwala: ikhebula le-radiation elixhumeke ngokuphambano liyakhuphuka lisuka ku-70°C elingaxhunywanga liye ku-90°C, 105°C, kanye no-125°C.
Ukumelana nokufakwa okukhulu kwe-insulation: Njengoba i-radiation cross-linking igwema ukusetshenziswa kwe-hydroxide njenge-flame retardant, ivimbela ukuxhumanisa ngaphambili ngesikhathi sokuxhumanisa kanye nokuncipha kokumelana nokufakwa kwe-insulation ngenxa yokumuncwa komswakama emoyeni ngongqimba lwe-insulation.Lokhu kuqinisekisa inani lokumelana nokufakwa kwe-insulation.
Izinga lomkhiqizo ozinzile: Izinga lezintambo ze-silane ezixhumene ngokuphambana (ezaziwa kabanzi ngokuthi izintambo zamanzi afudumele) lithintwa izinga lokushisa lamanzi, inqubo yokukhishwa kwe-extrusion, izithasiselo ezixhumanisayo nezinye izici, futhi ikhwalithi ayizinzile, kuyilapho ikhwalithi yokuphambana kwemisebe. -izintambo ezixhunywe kuncike kugongolo lwe-electron.Umthamo we-irradiation ulawulwa yikhompyutha, okunciphisa izici zomuntu, ngakho ikhwalithi izinzile.
I-high flame retardant: Kusetshenziswa izinto ezivimbela amalangabi aphezulu, futhi i-ZA, ZB, ZC, nezintambo kungaklanywa ngokwezidingo zamakhasimende.Ukusebenza kwe-flame retardant kuphumelele ukuhlolwa kokuvutha okucaciswe ku-GB/T 1966-2005.
Ubuthi obungenayo i-halogen, ubuthi obuphansi, intuthu ephansi: ubuncane bokudluliswa kokukhanya kwezintambo ezikwazi ukumelana nomlilo zesigaba sokuqala nezintambo ezikwazi ukumelana nomlilo azikho ngaphansi kwama-80%, kanti ubuncane bokudluliswa kokukhanya kwezinye izintambo lapho kuvutha abukho ngaphansi. kunama-60%.Inani le-acidity PH legesi evuthayo akufanele libe ngaphansi kuka-4.3, futhi ukuqhutshwa kwe-conductor akumele kube kukhulu kuno-10us/mm.
