Kulowa mu Silicon Carbide Radiation Tube: "Katswiri Wolimbana ndi Kutentha Kwambiri" mu Kutentha kwa Industrial

Kutenthetsa ndi gawo lofunikira koma lofunikira kwambiri pazinthu zambiri zopanga mafakitale. Kuyambira zitsulo kutentha kutentha kwa ceramic sintering, ndipo ngakhale processing wa zipangizo zina zapadera, khola, kothandiza, ndi chosinthika Kutentha zipangizo chofunika. Muzochitika izi ndi zofunika kwambiri kutentha ndi kulimba,silicon carbide radiationmachubu akukhala chisankho cha mabizinesi ochulukirachulukira chifukwa chaubwino wawo wapadera.
Anthu ena atha kukhala ndi chidwi, kodi silicon carbide radiation chubu ndi chiyani? Mwachidule, ndi chinthu chotenthetsera cha tubular chomwe chimapangidwa makamaka ndi silicon carbide ceramics, yomwe nthawi zambiri imagwiritsidwa ntchito limodzi ndi mawaya otenthetsera, ndodo zotenthetsera ndi zida zina zamkati, ndipo imagwira ntchito ya "chotenthetsera kutentha" m'mafakitale ndi zida zina. Komabe, zapadera zake zimakhala chifukwa chakuti sizimapanga mwachindunji kutentha kwapamwamba, koma m'malo mwake zimatengera kutentha kumalo opangira ntchito zomwe zimafunika kutenthedwa mu mawonekedwe a ma radiation kudzera m'zinthu zotentha zamkati zomwe zimakulungidwa mozungulira, komanso kuteteza zigawo zamkati kuchokera kumlengalenga wovuta mkati mwa ng'anjo.
Zikafika pazabwino zamachubu a silicon carbide radiation, "kutentha kwambiri kukana" ndiye chizindikiro chake chachikulu. Machubu otenthetsera zitsulo wamba amatha kukhala ndi mapindikidwe ndi okosijeni pa kutentha kwa madigiri mazana angapo Celsius, pomwe zoumba za silicon carbide zomwe zimakhala ndi kukana kutentha kwambiri. Ngakhale m'malo otentha kwambiri kuposa 1300 ℃, amatha kukhala okhazikika komanso osawonongeka mosavuta. Makhalidwewa amalola kuti azolowere zochitika zambiri zotentha kwambiri, monga kutentha kwa sintering kwazitsulo zina zapadera zomwe nthawi zambiri zimaposa 1200 ℃, ndi machubu a silicon carbide radiation amatha kugwira ntchito modalirika m'malo oterowo kwa nthawi yayitali.
Kuphatikiza pa kukana kutentha kwapamwamba, "kutsutsa kwa corrosion" kumakhalanso kwakukulu kwambiri. Munjira zambiri zotenthetsera mafakitale, pakhoza kukhala acidic, mpweya wa alkaline kapena zinthu zina zowononga mu uvuni, zomwe zimatha kuwononga zinthu zotentha ndikufupikitsa moyo wautumiki wa zida. Kukhazikika kwa mankhwala a silicon carbide chuma ndi kolimba, ndipo sikophweka kuchitapo kanthu ndi zinthu zowononga izi, zomwe zikutanthauza kuti zimatha kukhalabe zolimba m'malo ovuta a ng'anjo, kuchepetsa kuchuluka kwa zida m'malo mwake, ndipo m'kupita kwanthawi, kumachepetsanso kupanga ndi kukonza ndalama zamabizinesi.
Kuphatikiza apo, "kutentha kotentha" kwa machubu a silicon carbide radiation ndikofunikiranso kutchulidwa. Matenthedwe ake matenthedwe ndi abwino, omwe amatha kusamutsa mwachangu kutentha kopangidwa ndi zinthu zotentha zamkati ndikutenthetsa ntchito ndi ma radiation. Njira yotenthetsera iyi sikuti imangotentha mwachangu, komanso imapangitsa kuti kutentha kwa mkati mwa ng'anjo kukhale kofanana, kupewa kutenthedwa kwapanyumba kapena kutentha kosakwanira. Izi ndi zofunika kwambiri kuonetsetsa kugwirizana kwa mankhwala processing khalidwe. Mwachitsanzo, mu kutentha mankhwala mbali zitsulo, kutentha chifanane mwachindunji zimakhudza kuuma, toughness, ndi katundu zina za mbali, ndi pakachitsulo carbide poizoniyu machubu angapereke thandizo khola pankhaniyi.

Zachidziwikire, kugwiritsa ntchito machubu a silicon carbide radiation sikopanda malire. Mwachitsanzo, mtengo wawo ndi wokwera kwambiri kuposa machubu wamba azitsulo zotentha, ndipo chifukwa cha mawonekedwe a zida za ceramic, amayenera kupewa kugunda kwakukulu pakuyika ndikugwiritsa ntchito kuti asawonongeke. Koma kwa mafakitale omwe ali ndi zofunika kwambiri pakutenthetsa kutentha, kuwonongeka kwa chilengedwe, ndi mtundu wazinthu, kukhazikika, kuchita bwino, komanso moyo wautali zomwe zimabweretsa nthawi zambiri zimabwezera zovuta zazing'onozi.
Masiku ano, ndi chitukuko cha mafakitale opangira zinthu zolondola komanso zapamwamba, zofunikira pazida zotenthetsera zikuchulukiranso nthawi zonse. Monga chinthu chabwino kwambiri chotenthetsera mafakitale, machubu a silicon carbide radiation pang'onopang'ono amatenga gawo lalikulu m'magawo monga zoumba, zitsulo, ndi zamagetsi. Sizingakhale zokopa maso monga matekinoloje ena omwe akubwera, koma ndi khalidwe ili la "kumamatira ku malo ake" mwakachetechete m'malo ovuta kwambiri zomwe zimapangitsa kuti ikhale yofunikira kwambiri "katswiri wosamva kutentha" pakupanga mafakitale, kupereka zitsimikizo zodalirika za njira zosiyanasiyana zotenthetsera zofunikira kwambiri.
