Crucible ndi Sagger

Chophimba ndi mphika wa ceramic womwe umagwiritsidwa ntchito kusunga chitsulo kuti chisungunuke mu uvuni. Ichi ndi chophimba chapamwamba kwambiri, chapamwamba chomwe chimagwiritsidwa ntchito ndi makampani opanga zitsulo.

Chophikira chimafunika kuti chipirire kutentha kwambiri komwe kumakumana nako mu zitsulo zosungunuka. Chophikiracho chiyenera kukhala ndi malo osungunuka kwambiri kuposa chitsulo chomwe chikusungunuka ndipo chiyenera kukhala ndi mphamvu zabwino ngakhale chitakhala choyera.

Chophimba cha silicon carbide chotentha kwambiri ndi mipando yabwino kwambiri ya uvuni wa mafakitale, yoyenera kuwotcha ndi kusungunula zinthu zosiyanasiyana, ndipo imagwiritsidwa ntchito kwambiri mu mankhwala, mafuta, kuteteza chilengedwe ndi madera ena. Chophimba cha silicon carbide ndiye gawo lalikulu la mankhwala a silicon carbide germanium, chomwe chili ndi mawonekedwe olimba kwambiri. Kulimba kwa chophimba cha silicon carbide kuli pakati pa corundum ndi diamondi, mphamvu yake yamakina ndi yayikulu kuposa ya corundum, yokhala ndi kutentha kwakukulu, kotero imatha kusunga mphamvu zambiri.

Choviikidwa ndi choviikidwa ndi RBSiC/SISIC ndi choviikidwa ndi ceramic chopangidwa ndi ceramic. Chifukwa chakuti chimaposa magalasi pankhani yolimbana ndi kutentha, chimagwiritsidwa ntchito bwino ngati choviikidwacho chikutenthedwa ndi moto. Choviikidwa ndi chimodzi mwa mipando yofunika kwambiri ya uvuni yowotcha porcelain. Mitundu yonse ya porcelain iyenera kuyikidwa mu saggers poyamba kenako mu uvuni kuti ikawotchedwe.

Chotsukira cha silicon carbide chosungunula ndiye gawo lalikulu la zida zamankhwala, ndi chidebe chimodzi chomwe chingagwiritsidwe ntchito kusungunula, kuyeretsa, kutentha ndi kuchitapo kanthu. Mitundu ndi makulidwe ambiri akuphatikizidwa; palibe malire pakupanga, kuchuluka kapena zipangizo.

Chophikira chosungunuka cha silicon carbide ndi chidebe cha ceramic chooneka ngati mbale yakuya chomwe chimagwiritsidwa ntchito kwambiri mumakampani opanga zitsulo. Zinthu zolimba zikatenthedwa ndi moto waukulu, payenera kukhala chidebe choyenera. Ndikofunikira kugwiritsa ntchito chophikira potenthetsera chifukwa chimatha kupirira kutentha kwambiri kuposa magalasi komanso kuonetsetsa kuti chili choyera kuchokera ku kuipitsidwa. Chophikira chosungunuka cha silicon carbide sichingadzazidwe kwambiri ndi zinthu zosungunuka chifukwa zinthu zotenthetsera zimatha kuwiritsidwa ndikupopera. Kupanda kutero, ndikofunikiranso kusunga mpweya wozungulira momasuka kuti pakhale kusintha kwa okosijeni.

Zindikirani:
1. Sungani youma komanso yoyera. Iyenera kutenthedwa mpaka 500℃ pang'onopang'ono musanagwiritse ntchito. Sungani zophimba zonse pamalo ouma. Chinyezi chingayambitse zophimba kusweka zikatenthedwa. Ngati zakhala zikusungidwa kwa kanthawi, ndi bwino kubwerezanso kutenthetsa. Zophimba ku silicon carbide ndizomwe sizingatenge madzi osungidwa ndipo nthawi zambiri sizifunika kutenthedwa musanagwiritse ntchito. Ndibwino kuyatsa chophimba chatsopano ku kutentha kofiira musanagwiritse ntchito koyamba kuti chizimitse ndikulimbitsa zophimba ndi zomangira za fakitale.
2. Ikani zinthuzo mu silicon carbide melting crucible malinga ndi kuchuluka kwake ndipo sungani malo oyenera kuti kutentha kusamasweke. Zinthuzo ziyenera kuyikidwa mu crucible mosasamala. MUSAKWANIRE "kunyamula" crucible, chifukwa zinthuzo zidzakula zikatenthedwa ndipo zitha kuswa ceramic. Zinthuzi zikasungunuka kukhala "chidendene", sungani mosamala zinthu zina mu dziwe kuti zisungunuke. (CHENJEZO: Ngati pali chinyezi chilichonse pa chinthu chatsopanocho, nthunzi idzaphulika). Apanso, musapake chitsulocho mwamphamvu. Pitirizani kuyika zinthuzo mu melting mpaka kuchuluka komwe mukufuna kusungunuka.
3. Ma crucible onse ayenera kugwiritsidwa ntchito ndi ma clamp oyenera (chida chonyamulira). Ma clamp osayenera angayambitse kuwonongeka kapena kulephera kwathunthu kwa crucible panthawi yovuta kwambiri.
4. Pewani moto wamphamvu wokhuthala womwe ukuyaka mwachindunji pa chotenthetsera. Izi zidzafupikitsa nthawi yogwiritsira ntchito chifukwa cha kukhuthala kwa zinthuzo.
5. Musayike silicon carbide yotenthedwa yosungunuka pa chitsulo chozizira kapena pamwamba pa matabwa nthawi yomweyo. Kuzizira mwadzidzidzi kungayambitse ming'alu kapena kusweka ndipo pamwamba pa matabwa pangayambitse moto. Chonde siyani pa njerwa kapena mbale yolimba ndipo mulole kuti izizire mwachibadwa.
