Ikhebula Elifakwe Ukushisa Kwamaminerali (Ikhebula le-MI) likhebula elisebenza kahle kakhulu elingashisi umlilo elisekelwe ohlelweni lwezinto zekhebula ezingaphili ngokuphelele. Ngokungafani nezintambo ezivamile ezithembele ezintweni zokufakelwa ukufudumala kwe-polymer njenge-PVC,I-XLPE, futhiI-LSZH, ikhebula le-MI lakhiwe kusetshenziswa umqhubi wethusi, igobolondo lethusi elingenamthungo, kanye nezinto zokuvikela ezingaphili ze-magnesium oxide (MgO) njengesakhiwo salo esiyinhloko. Lolu hlelo lwezinto lunquma ngokuyisisekelo ukusebenza kwalo okuzinzile ngaphansi kwezimo zokushisa okuphezulu kanye nomlilo.
Ngokombono wokuthuthukiswa kwezinto zekhebula, izinhlelo zezinto ezingaphili ziqeda ngempumelelo izinkinga zokubola, ukuncibilika, kanye nokukhishwa kwentuthu enobuthi okwenzeka ezintweni eziphilayo ngaphansi kwamazinga okushisa aphezulu. Lokhu kwenza ikhebula le-MI libe yisisombululo esibalulekile sezintambo ezingashi, izintambo ezishisa kakhulu, kanye nezinto zekhebula zesistimu yamandla ezibalulekile.
Isakhiwo Sezinto Nokwakheka Kwazo
Ukusebenza kwekhebula le-MI kunqunywa kakhulu uhlelo lwayo lwezinto zekhebula eziyinhloko. I-conductor yenziwe nge-conductor yethusi ehlanzekile kakhulu, enikeza ukuhanjiswa kukagesi okuhle kakhulu kanye nokumelana okuphansi, okwenza kube yingxenye ebalulekile yezinto zekhebula lamandla.
Isendlalelo sokuvikela sisebenzisa i-magnesium oxide (i-MgO insulation), into evamile yokuvikela ikhebula ye-inorganic enephuzu lokuncibilika elingaphezu kuka-2800°C. Igcina ukusebenza kahle kwe-dielectric okuzinzile ngisho nangaphansi kwamazinga okushisa aphezulu, isebenza njengento eyinhloko evumela ukumelana nomlilo.
Ingqimba yangaphandle inesigxobo sethusi esingenamthungo, esihlinzeka ngokuvikelwa kwemishini kanye nokumelana nokugqwala. Iphinde inikeze ukusebenza okuhle kakhulu kokushisa kanye nokusebenza kokuvikela nge-electromagnetic (EMI shielding). Ngaphezu kwalokho, isigxobo sethusi singasebenza njengomqhubi womhlaba, okwenza kube lula ukuklama uhlelo futhi kuthuthukiswe ukuthembeka kokusebenza.
Ukusebenza Komlilo kanye Nezinzuzo Zezinto Ezibonakalayo
Ngaphansi kwezimo zomlilo, umehluko ezinhlelweni zezinto uba bucayi. Izinto zekhebula ze-polymeric zendabuko ngokuvamile ziqala ukubola noma ukwehluleka ukushisa emazingeni okushisa aphakathi kuka-300°C no-500°C, zikhiphe intuthu namagesi ayingozi.
Ngokuphambene nalokho, ikhebula le-MI lisekelwe ohlelweni lokuvikela olungaphili, futhi lingagcina ubuqotho bukagesi ngaphansi kokuchayeka ngqo elangeni cishe ku-950°C. Liyakwazi ukusebenza ngokuqhubekayo imizuzu engaphezu kwengu-90, lihlangabezana nezindinganiso zomhlaba wonke zokumelana nomlilo njenge-BS 6387 kanye ne-IEC 60331.
Okwamanje, izinto zayo zekhebula ezingashi azishi, azikhiqizi intuthu, futhi azikhiphi amagesi anobuthi, okwenza ikhebula le-MI libe yisisombululo esivamile sezinto zekhebula zokusinda emlilweni ezisetshenziswa kabanzi ezinhlelweni zokuphakelwa kwamandla eziphuthumayo kanye nokuvikela umlilo.
Izinzuzo Nezinselele Ezisekelwe Ezinto Ezibonakalayo
Ngokombono wezinto zekhebula, ikhebula le-MI linikeza ukumelana nomlilo kwangaphakathi, amandla aphezulu okuthwala ugesi, kanye nokuphila isikhathi eside (ngokuvamile iminyaka engama-40-60). Lifanelekela izindawo ezinokushisa okuphezulu, ezinomswakama, neziyingozi.
Kodwa-ke, ngenxa yokusetshenziswa okukhulu kwezinto zethusi kanye nokufakwa kwe-magnesium oxide (ukufakwa kwe-MgO), izindleko zezinto zizonke ziphakeme kunezinhlelo zekhebula ezivamile. Ngaphezu kwalokho, isakhiwo esingenazinto eziphilayo ngokuphelele siphumela ekuqineni okuphezulu, okubeka izidingo eziqinile ekufakweni kwekhebula, ukusebenza kahle kokugoba, kanye nezinqubo zokuvala zokuqeda.
Imiklamo yekhebula le-MI eguquguqukayo ingathuthukisa ukusebenza kokufakwa, kodwa futhi yandisa ubunzima bezinto zokwakha kanye nokukhiqiza.
Izicelo Ezijwayelekile
Ngenxa yokusebenza kwayo okuhle kakhulu kwezintambo ezingashisi, ikhebula le-MI lisetshenziswa kabanzi ezinhlelweni zokuvikela umlilo ezakhiweni eziphakeme, ingqalasizinda yezokuthutha ngojantshi, izikhungo zomphakathi ezinkulu, kanye nezindawo zamakhemikhali ezinokushisa okuphezulu kanye nezingozi ezivuthayo.
Kulezi zinhlelo zokusebenza, ukusebenza okuzinzile kohlelo lwayo lwezinto zekhebula kuqinisekisa ukunikezwa kwamandla okuqhubekayo ngaphansi komlilo noma izimo ezimbi kakhulu, okwenza kube yisisombululo esibalulekile sezinhlelo zamandla omthwalo obalulekile.
Isiphetho: Izitayela Zokuthuthukiswa Kwezinto Zekhebula
Ngokombono wezitayela zokuthuthukiswa kwezinto zekhebula, ikhebula le-MI limelela ushintsho olukhulu kusuka ezintweni zokuvikela izinto eziphilayo kuya ezintweni zokuvikela izinto ezingaphili.
Kubahlinzeki bezinto zekhebula, amakhono okulawula ubumsulwa, ukusatshalaliswa kosayizi wezinhlayiya, ukumelana nomswakama, kanye nezakhiwo zokugeleza kwe-magnesium oxide (i-MgO insulation), kanye nokuhlinzekwa okuzinzile kwezinto zokuqhuba zethusi kanye nezesigxobo sethusi, kuzoba yizici ezibalulekile zokuncintisana emakethe yezinto zekhebula ezingashisi umlilo.
Siyaqhubeka nokugxila futhi sinikeze izixazululo zezinto zekhebula ezihlobene, sisekela amakhasimende ekusebenziseni ikhebula le-MI kanye nezinye izinhlelo zekhebula ezingashisi ezisebenza kahle kakhulu.
