Izintambo ezingashibheka izintambo ezingagcina ukusebenza okuphephile isikhathi esithile ngaphansi kwesimo somlilo ovuthayo.izinga lezwe lami lezwe lami i-GB12666.6 (elifana ne-IEC331) lihlukanisa ukuhlolwa kokumelana nomlilo kube amamaki amabili, A no-B. Izinga lokushisa lelangabi lebanga A lingu-950 ~ 1000℃, futhi isikhathi sokunikezwa komlilo okuqhubekayo yi-90min.Izinga lokushisa lelangabi lebanga B lingu-750 ~ 800 ℃, futhi isikhathi esiqhubekayo sokunikeza umlilo imizuzu engu-90.min, phakathi naso sonke isikhathi sokuhlola, isampula kufanele imelane nenani likagesi elilinganiselwe elishiwo umkhiqizo.
Izintambo ezikwazi ukumelana nomlilo zisetshenziswa kakhulu ezakhiweni eziphakeme, imizila yezitimela engaphansi komhlaba, emigwaqweni engaphansi komhlaba, iziteshi ezinkulu zikagesi, amabhizinisi abalulekile ezimboni nezimayini nezinye izindawo ezihlobene nokuphepha komlilo nokucisha umlilo nokusindisa ukuphila, njengezintambo zikagesi kanye nemigqa yokulawula. wezinsiza eziphuthumayo njengemishini yokucisha umlilo namalambu aqondisa izimo eziphuthumayo.
Njengamanje, izintambo eziningi nezintambo ezingashi nomlilo ekhaya naphesheya zisebenzisa izintambo ezivalwe ngamaminerali e-magnesium oxide kanye nezintambo ze-mica tape-nxeba ezingashi;phakathi kwabo, ukwakheka kwe-magnesium oxide mineral insulated izintambo kuboniswa esithombeni.
Ikhebula le-Magnesium oxide mineral insulated iwuhlobo lwekhebula elikwazi ukumelana nomlilo elisebenza kangcono.Yenziwe nge-copper core, i-copper sheath, ne-magnesium oxide insulating material.Ibizwa ngokuthi i-MI (minerl insulated cables) ngamafuphi.Ungqimba lwekhebula olukwazi ukumelana nomlilo lwakhiwe ngokuphelele izinto ezingaphili, kuyilapho ungqimba oluphikisayo lwezintambo ezivamile ezikwazi ukumelana nomlilo lwakhiwe izinto ezingaphili kanye nezinto eziphilayo ezivamile.Ngakho-ke, ukusebenza okungavimbeli umlilo kwezintambo ze-MI kungcono kunokwezintambo ezivamile ezikwazi ukumelana nomlilo futhi ngeke kubangele ukugqwala ngenxa yokusha nokubola.igesi.Izintambo ze-MI zinezakhiwo ezinhle ezikwazi ukumelana nomlilo futhi zingasebenza ekushiseni okuphezulu okungu-250°C isikhathi eside.Ngesikhathi esifanayo, azikwazi ukuqhuma, ukumelana nokugqwala okuqinile, umthamo omkhulu wokuthwala, ukumelana nemisebe, amandla aphezulu emishini, usayizi omncane, isisindo esilula, impilo ende, kanye nokukhethekile okungenantuthu.Nokho, intengo iyabiza, inqubo iyinkimbinkimbi, futhi ukwakhiwa kunzima.Ezindaweni zokunisela uwoyela, isakhiwo sokhuni esibalulekile izakhiwo zomphakathi, izindawo ezishisa kakhulu kanye nezinye izikhathi ezinezidingo eziphakeme zokumelana nomlilo kanye nomnotho owamukelekayo, lolu hlobo lwekhebula olunokumelana nomlilo okuhle lungasetshenziswa, kodwa lungasetshenziswa kuphela ukumelana nomlilo we-Low voltage. izintambo.
Ikhebula elikwazi ukumelana nomlilo esongwe ngaloi-mica tapeulinyazwa ngokuphindaphindiwe ngezendlalelo eziningi ze-mica tape ngaphandle kwe-conductor ukuvimbela ilangabi ukuthi lingashi, ngaleyo ndlela kwelula isikhathi sokusebenza okuphephile nokugcina ulayini ungavinjiwe isikhathi esithile.
i-magnesium oxide
Impushana emhlophe e-amorphous.Ayinaphunga, ayinambitheki futhi ayinabuthi.Inokumelana nokushisa okuqinile okuphezulu nokuphansi (izinga lokushisa eliphakeme elingu-2500 ℃, izinga lokushisa eliphansi -270 ℃), ukumelana nokugqwala, ukwahlukanisa, ukuguquguquka okuhle kwe-thermal kanye nezakhiwo ezibonakalayo, ikristalu engenambala futhi esobala, indawo encibilikayo engu-2852 ℃.I-Magnesium oxide inezinto eziphakeme ezikwazi ukumelana nomlilo nezivimbela ukushisa, futhi inezinga eliphezulu lokuncibilika.Isetshenziswa ekukhiqizeni izintambo ze-magnesium oxide mineral insulated ukumelana nomlilo.
I-Mica tape
I-Mica iwumthombo wamaminerali angenalutho, obonakala ngokufaka ukushisa, ukumelana nokushisa okuphezulu, ukucwebezela, izakhiwo ezinzile ngokomzimba namakhemikhali, ukufakwa kahle kokushisa, ukuqina, ukuqina nokungashi, futhi ihlutshulwe ibe yizici ezinwebekayo zamashidi abonakalayo.
I-Mica tapeyenziwe nge-flake mica powder ibe yiphepha le-mica, elinamathela endwangu ye-fiber yengilazi ene-adhesive.
Indwangu yengilazi enamathiselwe ohlangothini olulodwa lwephepha le-mica ibizwa ngokuthi "i-tape enezinhlangothi ezimbili", futhi leyo enamathiselwe ezinhlangothini zombili ibizwa ngokuthi "i-tape enezinhlangothi ezimbili".Phakathi nenqubo yokukhiqiza, izingqimba eziningana zesakhiwo zihlanganiswa ndawonye, zomiswe kuhhavini, ziboshwe, futhi zisikwe zibe amateyipu anobukhulu obuhlukahlukene.
I-Mica tape, eyaziwa nangokuthi i-mica tape engashi, yenziwa (umshini we-mica tape).Iwuhlobo lwempahla evikela umlilo.Ngokusetshenziswa kwayo, ingahlukaniswa ibe: i-mica tape yama-motor kanye ne-mica tape yezintambo.Ngokusho kwesakhiwo, ihlukaniswe: ibhande eliphindwe kabili, ibhande elilodwa-side, ibhande lama-3-in-one, ibhande lefilimu eliphindwe kabili, ibhande lefilimu eyodwa, njll Ngokusho kwe-mica, ingahlukaniswa: i-mica tape, i-phlogopite mica tape, ne-muscovite tape.
(1) Ukusebenza okujwayelekile kwezinga lokushisa: i-synthetic mica tape iyona engcono kakhulu, ilandelwa yi-muscovite tape, kanye ne-phlogopite tape impofu.
(2) Ukusebenza kwe-insulation ekushiseni okuphezulu: i-synthetic mica tape iyona engcono kakhulu, ilandelwa yi-phlogopite mica tape, kanye ne-muscovite tape impofu.
(3) Ukusebenza kokumelana nokushisa okuphezulu: I-synthetic mica tape, ayinawo amanzi ayikristalu, indawo encibilikayo engu-1375 ° C, ukumelana nokushisa okuphezulu kakhulu, i-phlogopite ikhipha amanzi ayikristalu angaphezu kuka-800 ° C, ilandelwa ukumelana nokushisa okuphezulu, i-muscovite ikhulula amakristalu ku-600 ° C Amanzi, ukumelana nezinga lokushisa eliphansi.
Irabha ye-ceramic refractory abicah
Ngenxa yemikhawulo yemibandela yenqubo, ikhebula elingashi eligoqwe nge-mica tape ngokuvamile libangela ukukhubazeka emalungeni.Ngemuva kokukhishwa kwe-ablation, i-mica tape iba brittle futhi kulula ukuwa, okuholela kumphumela omubi wokumelana nomlilo.I-insulation, kulula ukuwa uma inyakaziswa, ngakho-ke kunzima ukuqinisekisa ukuxhumana okuphephile nokushelelayo kokuxhumana kwesikhathi eside namandla uma kwenzeka umlilo.
Izintambo ze-Magnesia mineral insulated ukumelana nomlilo zidinga ukungenisa imishini ekhethekile, intengo ibiza kakhulu, kanye nokutshalwa kwezimali okukhulu;ngaphezu kwalokho, i-sheath yangaphandle yale khebula yonke ithusi, ngakho-ke izindleko zalo mkhiqizo nazo zenza lo mkhiqizo ubize;plus Lolu hlobo lwekhebula lunezidingo ezikhethekile ohlelweni lokukhiqiza, ukucubungula, ukuthutha, ukubeka umugqa, ukufakwa nokusetshenziswa, futhi kunzima ukuthandwa nokusetshenziswa ngezinga elikhulu, ikakhulukazi ezakhiweni zomphakathi.
