Njirayi ikuphatikizapo kuponyera zitsulo zopanda chitsulo, makamaka njira yokonzekera yamphamvu kwambiri ya graphite silicon carbide crucible yosungunula zitsulo.

[Ukadaulo Wapambuyo] Ma crucibles apadera a graphite silicon carbide amagwiritsidwa ntchito makamaka popanga zitsulo zopanda chitsulo, komanso pobwezeretsa ndi kuyenga zitsulo zamtengo wapatali, komanso kupanga zinthu zomwe zimatentha kwambiri komanso zosagwira dzimbiri zomwe zimafunikira mapulasitiki, zitsulo zadothi, magalasi, simenti, labala, kupanga mankhwala, komanso zotengera zosagwira dzimbiri zomwe zimafunikira pamakampani a petrochemical.

Mapangidwe apadera a graphite silicon carbide crucible formulations ndi njira zopangira amapanga zinthu zomwe zimakhala ndi moyo wamasiku 55, zomwe ndi zazifupi kwambiri.Ndalama zogwiritsira ntchito ndi kupanga zikupitirira kuwonjezeka, ndipo kuchuluka kwa zinyalala zomwe zimapangidwira ndizokweranso.Choncho, kufufuza mtundu watsopano wa graphite silicon carbide crucible ndi njira yake yopangira ndi vuto lofulumira kuthetsa, chifukwa ma crucibleswa ali ndi ntchito zazikulu m'mafakitale osiyanasiyana a mankhwala.

[0004] Kuti athetse mavuto omwe ali pamwambawa, njira yokonzekera zitsulo zamphamvu za graphite silicon carbide zosungunula zitsulo zimaperekedwa.Zogulitsa zomwe zakonzedwa motsatira njira iyi zimagonjetsedwa ndi kutentha kwakukulu ndi dzimbiri, zimakhala ndi moyo wautali wautumiki, komanso zimapulumutsa mphamvu, kuchepetsa utsi, kuteteza chilengedwe, komanso kuwononga kwambiri zinyalala panthawi yopanga, kupititsa patsogolo kayendedwe kake ndi kugwiritsa ntchito zinthu.

Njira yokonzekera zitsulo zamphamvu za graphite silicon carbide zosungunula zitsulo zimaphatikizapo izi:

1. Kukonzekera kwazinthu zopangira: Silicon carbide, graphite, dongo, ndi zitsulo zachitsulo zimayikidwa muzitsulo zawo ndi crane, ndipo pulogalamu ya PLC imangoyang'anira kutulutsa ndi kulemera kwa chinthu chilichonse malinga ndi chiŵerengero chofunika.Mavavu a pneumatic amawongolera kutulutsa, ndipo masensa osachepera awiri olemera amayikidwa pansi pa chophatikizira chilichonse.Pambuyo kuyeza, zidazo zimayikidwa mu makina osakaniza ndi ngolo yosunthika.Kuwonjezera koyamba kwa silicon carbide ndi 50% ya kuchuluka kwake.
2. Kusanganikirana kwachiwiri: Zopangira zitasakanizidwa mu makina osakaniza, zimatulutsidwa mu chopukutira chotchinga, ndipo zinthu zomwe zili mu chopukusira chamadzi zimakwezedwa ku chophatikizira chophatikizira ndi chokwezera chidebe kuti chisakanize chachiwiri.Chipangizo chochotsera chitsulo chimayikidwa pa doko lotayira la chikepe cha ndowa, ndipo chipangizo chowonjezera madzi chimayikidwa pamwamba pa chophatikizira chophatikizira kuti chiwonjezere madzi poyambitsa.Mlingo wowonjezera madzi ndi 10L / min.
3. Kuyanika kwazinthu: Zinthu zonyowa pambuyo posakaniza zimawumitsidwa mu chipangizo chowumitsa pa kutentha kwa 120-150 ° C kuchotsa chinyezi.Pambuyo kuyanika kwathunthu, zinthuzo zimachotsedwa kuti ziziziziritsa mwachilengedwe.
4. Kuphwanya ndi kuwunika: Zinthu zowuma zowuma zimalowa m'chida chophwanyira ndikuwunika kuti chisaphwanyidwe, kenako ndikulowa mu chopondapo chomenyera nkhondo kuti chiphwanyidwenso, ndikudutsa pazida zowonera ma mesh 60.Tinthu tating'onoting'ono toposa 0.25mm timabwezeredwa kuti tidzabwezerensonso kuti tipitirize kuphwanyidwa, kuphwanya, ndikuwunika, pomwe tinthu tating'ono kuposa 0.25mm timatumizidwa ku hopper.
5. Kukonzekera kwazinthu zachiwiri: Zida zomwe zili mu hopper yotulutsa zimatumizidwa ku makina ophatikizira kuti akonzekere kachiwiri.50% yotsala ya silicon carbide imawonjezedwa panthawi yokonzekera yachiwiri.Zipangizo pambuyo pokonzekera yachiwiri zimatumizidwa ku makina osakaniza kuti asakanikenso.
6. Kusakaniza kwachiwiri: Panthawi yachiwiri yosakanikirana, njira yapadera yokhala ndi viscosity imawonjezeredwa ku hopper yosakaniza kudzera mu njira yapadera yowonjezera chipangizo chokhala ndi mphamvu yokoka.Njira yapaderayi imayesedwa ndi chidebe cholemera ndikuwonjezeredwa ku hopper yosakaniza.
7. Kukanikiza ndi kuumba: Zida zitatha kusakanikirana kwachiwiri zimatumizidwa ku makina osindikizira a isostatic.Pambuyo pakutsitsa, kuphatikizika, kupukuta, ndikuyeretsa mu nkhungu, zidazo zimakanikizidwa mu makina osindikizira a isostatic.
8. Kudula ndi kudula: Izi zikuphatikizapo kudula kutalika ndi kudula ma crucible burrs.Kudula kumachitidwa ndi makina odulira kuti adule crucible mpaka kutalika kofunikira, ndipo ma burrs atatha kudula amakonzedwa.
9. Kuyanika: Chophimbacho, chitatha kudulidwa ndikudulidwa mu sitepe (8), chimatumizidwa ku ng'anjo yowumitsa, ndi kutentha kwa 120-150 ° C.Pambuyo kuyanika, imasungidwa kutentha kwa maola 1-2.Uvuni wowumitsa uli ndi makina osinthira ma air duct, omwe amakhala ndi mbale zingapo zosinthika za aluminiyamu.Ma mbale a aluminiyamu osinthikawa amakonzedwa m'mbali ziwiri zamkati mwa uvuni wowumitsa, ndi njira ya mpweya pakati pa mbale ziwiri zilizonse za aluminiyamu.Kusiyana pakati pa mbale ziwiri zilizonse za aluminiyamu zimasinthidwa kuti ziwongolere mpweya.
10. Kuwala: Kunyezimira kumapangidwa ndi kusakaniza zinthu zonyezimira ndi madzi, kuphatikizapo bentonite, dongo losungunuka, ufa wagalasi, ufa wa feldspar, ndi sodium carboxymethyl cellulose.The glaze ntchito pamanja ndi burashi pa glazing.
11. Kuwombera koyambirira: Chowotcha chokhala ndi glaze chimawotchedwa kamodzi mu uvuni kwa maola 28-30.Kuti kuwombera bwino bwino, bedi la ng'anjo ya labyrinth yokhala ndi zotsekera komanso kutsekeka kwa mpweya kumayikidwa pansi pa ng'anjoyo.Bedi la ng'anjo limakhala ndi thonje lotsekera pansi, ndipo pamwamba pa thonje losindikizira, pali nsanjika ya njerwa, kupanga bedi la labyrinth.
12. Impregnation: crucible yothamangitsidwa imayikidwa mu thanki yotsekera kuti ichotsedwe komanso kukakamiza kulowetsedwa.Njira yothetsera vutoli imatumizidwa ku thanki ya impregnation kudzera mu payipi yosindikizidwa, ndipo nthawi yoyamwitsa ndi mphindi 45-60.
13. Kuwombera kwachiwiri: crucible yoikika imayikidwa mu uvuni kuti iwomberenso kwa maola awiri.
14. Kupaka: Chophimbacho pambuyo powombera chachiwiri chimakutidwa ndi utoto wopangidwa ndi madzi wa acrylic resin pamwamba.
15. Zomwe zatsirizidwa: Chophimbacho chikatha, pamwamba pake amauma, ndipo atatha kuyanika, crucible imayikidwa ndikusungidwa.
