1. Intambo ye-Mica tape mineral efakwe i-corrugated copper sheathed
Ikhebula lethusi eligoqekile elifakwe i-Mica tape elenziwe ngomqhubi wethusi, i-mica tape insulation kanye nokucubungula okuhlanganisiwe kwe-copper shead, elinokusebenza okuhle komlilo, ubude obude obuqhubekayo, umthamo wokulayisha ngokweqile, ukonga okuhle njalo njalo.
Inqubo yokukhiqiza ikhebula lethusi elihlanganisiwe elifakwe i-corrugated copper sheath iqala ngokunamathela okuqhubekayo kwentambo yethusi noma induku yethusi, imicu eminingi yentambo yethusi iyasontwa, umqhubi ugoqwa ngokumelana nokushisa okuphezuluiteyipu ye-mica yokwenziwa(itheyiphu ye-mica ene-calcined ingasetshenziswa emikhiqizweni engena-halogen, intuthu ephansi kanye nobuthi obuphansi), ungqimba lokuvikela lugcwele i-fiber yengilazi engeyona i-alkali, futhi ikhebula ligoqwa ngetheyiphu ye-mica yokwenziwa engamelani nokushisa okuphezulu ukuze kwakheke ungqimba oluvikelayo. Ungqimba lwethusi luhlanganiswa ngepayipi yethusi ngemva kokuba itheyiphu yethusi isongwe nge-longitude, bese lwakhiwa ngo-corrugated rolling corrugated oqhubekayo. Izidingo ezithile zongqimba lwensimbi azikwazi ukudalulwa, futhi ungqimba lwe-polyolefin (intuthu ephansi engena-halogen) lungangezwa ngaphandle.
Uma kuqhathaniswa nezintambo ezifakwe i-magnesium oxide mineral insulated, imikhiqizo yekhebula le-mica tape mineral insulated corrugated copper sheathed, ngaphezu kokusebenza komlilo kuseduze kakhulu, ingafinyelela ubude obukhulu obuqhubekayo, ngaphakathi kwama-95 mm² ingenziwa futhi ibe izintambo zeqembu eziningi, ukuze kunqotshwe ukushiyeka kwezixhumi zekhebula ezinkulu. Kodwa-ke, i-corrugated copper pipe weld kulula ukuyiqhekeza, i-extrusion deformation kanye ne-single mica insulation, okubuye kwaba yisici sokuzalwa kwesakhiwo, futhi isidingo somthamo wenqubo yokufaka sisaphezulu kakhulu.
Indawo yokulawula ye-mica tape mineral insulated corrugated copper sheathed cable iwukukhetha izinto ze-mica belt ezishisa kakhulu kanye nenqubo yokushisela nokugoqa ikhebula le-copper sheathed. Ukukhethwa kwezinto ze-mica tape ezishisa kakhulu kuthinta ngqo ukusebenza komkhiqizo okungashisi umlilo. I-mica tape eningi kakhulu izodala ukuchithwa kwezinto, futhi okuncane kakhulu ngeke kufeze ukusebenza okungashisi. Uma ukushisela kwejakethi yethusi kungaqinile, ukushisela kwepayipi lethusi elihlanganisiwe kulula ukuqhekeka, ngasikhathi sinye, ukujula kokugingqa nakho kuyisihluthulelo sokulawula inqubo, umehluko ekujuleni kokugingqa kanye nephimbo lejakethi yethusi kuzoholela ekwehlukeni endaweni yangempela yejakethi yethusi, ngaleyo ndlela kuthinte ukumelana kwejakethi yethusi.
2. Ikhebula le-ceramic silicone raber (mineral) elifakwe i-insulated refractory
Irabha ye-silicone yobumbaIkhebula elivikela umlilo elifakwe amaminerali liwuhlobo olusha lwekhebula elivikela umlilo, ukuvikela kwalo kanye nesendlalelo sokuvikela umoya-mpilo kusetshenziswa izinto ezihlanganisiwe zerabha ye-silicone ye-ceramic, le nto ithambile njengerabha ye-silicone evamile ngaphansi kwezimo zokushisa ezijwayelekile, futhi izokwakha igobolondo eliqinile le-ceramic ngaphansi kwezimo zokushisa eziphakeme ezingama-500 ℃ nangaphezulu. Ngesikhathi esifanayo, ukusebenza kokuvikela kuyagcinwa, futhi umugqa wekhebula usengagcina ukusebenza okuvamile isikhathi esithile uma kwenzeka umlilo, ukuze kusizwe umsebenzi wokusindisa nokunciphisa ukulimala kanye nokulahlekelwa yimpahla ngangokunokwenzeka.
Ikhebula le-ceramic silicone raber elifakwe insimbi evikelayo enesendlalelo sokuvikela esivimbelayo (izinto ezihlanganisiwe ze-ceramic silicone rubber) njenge-core cable, phakathi kwe-core cable linikezwa isendlalelo sokugcwalisa esimelana nokushisa okuphezulu, njengezinto ezihlanganisiwe ze-ceramic silicone rubber, kanye nesendlalelo esengeziwe sokuvikela, ukubukeka kwekhebula lesendlalelo sangaphandle se-sheath. Lolu hlobo lomkhiqizo lubonakala ngesendlalelo sokuvikela esivimbelayo senziwe nge-ceramic refractory silicone rubber, futhi igobolondo eliqinile elakhiwe ngemuva kokususwa kwegesi lisenokuvikela kagesi, okungavikela imigqa yokudlulisa kanye nokusabalalisa ekugugulekeni komlilo, ukuze kuqinisekiswe ukuhamba kahle kwamandla nokuxhumana, futhi kuwine isikhathi esibalulekile sokutakula nokukhulula abasebenzi uma kwenzeka umlilo uvutha. Imikhiqizo ye-ceramic retardant fire ifaka phakathi i-ceramic fire retardant silicone rubber, i-ceramic fire retardant tape kanye nentambo yokugcwalisa i-ceramic retardant fire.
Irabha ye-silicone ye-ceramic ekushiseni kwegumbi ayinabo ubuthi, ayinambitheki, inobumnene obuhle kanye nokunwebeka, emazingeni okushisa aphezulu angaphezu kuka-500 ° C, izingxenye zayo eziphilayo ngesikhathi esifushane kakhulu zibe yinto eqinile efana ne-ceramic, ukwakheka kwesendlalelo esihle sokuvimbela ukuvuvukala, futhi ngokukhula kwesikhathi sokushisa, ukukhuphuka kwezinga lokushisa, ubulukhuni bayo busobala kakhulu. Irabha ye-silicone ye-ceramic nayo inezakhiwo ezinhle zenqubo eyisisekelo futhi ingenziwa emigqeni evamile yokukhiqiza i-vulcanization eqhubekayo. Igebe kanye nokushisa kwekhebula kuyirabha ye-silicone ye-ceramic, evimba umoya-mpilo ngokuyisisekelo, futhi i-arm sheath exhumene isetshenziselwa ukwakha i-flexible serpentine tube sheath, engamelana nokucindezela kwe-radial futhi ivikele ikhebula ekulimaleni kwangaphandle kwemishini.
Amaphuzu okulawula ayinhloko enqubo yokukhiqizwa kwekhebula le-ceramic silicone raber elifakwe i-insulated refractory ikakhulukazi lisenquboni yokuvikela i-vulcanization kanye ne-interlocking ye-ceramic silicone raber.
Irabha ye-silicone ye-ceramic isezintweni eziyinhloko zerabha ye-silicone eshisayo ephezulu (i-HTV), okungukuthi, irabha ye-silicone ye-methyl vinyl 110-2 engezwe njenge-white carbon black, uwoyela we-silicone, i-porcelain powder nezinye izithasiselo ngemva kokuxuba bese ifakwa emshinini we-vulcanization ophindwe kabili we-24, engavulwanga ukuze kube nokuqina okumhlophe, ukwakheka okubi, idinga izinga lokushisa le-extruder ukuthi ligcine izinga lokushisa elithile eliphansi, uma seliphakeme kunaleli lokushisa, kuzoba khona isenzakalo seglue evuthiwe, okuholela ekususweni kwe-gum kanye nomonakalo kungqimba lokufakwa kwe-insulation. Ngaphezu kwalokho, ngenxa yokuqina okungekuhle kwerabha ye-silicone ye-ceramic, ayikwazi ukuthwalwa yi-screw iye ku-glue, okuholela ekungeneni kwe-glue entweni ekwi-screw, okuzophinde kubangele isenzakalo sokususwa kwe-gumming. Ukuze kugwenywe izinkinga ezingenhla, indlela yokumisa amathuluzi afanele e-extruder, indlela yokugcina isimo sokushisa esiphansi se-extruder, kanye nendlela yokwenza izinto zerabha esikulufini ngaphandle kwezikhala sekuyisihluthulelo sokuqinisekisa ikhwalithi yengqimba yokufakwa kwe-insulation.
Izivikelo ezixhumene zakhiwa yishubhu elijikelezayo elinama-edge hook angewona ajwayelekile. Ngakho-ke, ekukhiqizweni, indlela yokumisa uchungechunge lwezikhunta ezifanele ngokwezincazelo ezahlukene, ububanzi nobukhulu bomucu osetshenziselwa izivikelo ezixhumene kuyisihluthulelo sokukhiqiza izinkinga zenqubo njengokuntuleka kwebhande eliqinile.
