Kugwiritsa ntchito kwa silicon carbide ceramic

1, 'Mphamvu yoposa zonse' yazoumbaumba za silicon carbide
(1) Kuuma kwambiri, kosatha kuvala komanso kolimba
Kuuma kwa silicon carbide ceramics kuli pakati pa makampani opanga zinthu, chachiwiri pambuyo pa diamondi. Izi zikutanthauza kuti imakhala ndi mphamvu yolimba kwambiri yolimbana ndi kusweka ndi kukanda. Mwachitsanzo, ngati tiyerekeza zinthu wamba ndi nsapato wamba, zidzatha kwambiri mutazivala kwa kanthawi kochepa; silicon carbide ceramic imeneyo ili ngati nsapato za akatswiri oyenda panja, ngakhale zitasunthidwa movutikira bwanji, sizophweka kusweka. Monga zida zina zamakanika, zinthu wamba zimatha kusweka mwachangu mukamagwiritsa ntchito mwachangu komanso nthawi zambiri. Komabe, ngati silicon carbide ceramics igwiritsidwa ntchito, nthawi yawo yogwirira ntchito imatha kukulitsidwa kwambiri, nthawi zambiri kusintha kwa zigawo kungachepe, ndipo ndizotsika mtengo komanso zopanda nkhawa.
（2） Kukana kutentha kwambiri, osaopa "Phiri la Moto"
Tangoganizirani kuti pamalo otentha kwambiri a 1200 ℃, zinthu zambiri "sizingathe kupirira", kaya zimasungunuka ndi kusokonekera, kapena magwiridwe antchito awo amachepa kwambiri. Koma zoumba za silicon carbide zitha kukhalabe zosasintha mawonekedwe, osati kungosunga zinthu zokhazikika zakuthupi ndi zamankhwala, komanso mpaka 1350 ℃, zomwe zimapangitsa kuti zikhale "mfumu yamphamvu kwambiri" pakati pa zinthu zoumba. Chifukwa chake m'mafakitale ena otentha kwambiri, monga zoumba zotentha kwambiri, zosinthira kutentha, zipinda zoyaka moto, ndi zina zotero, zoumba za silicon carbide mosakayikira ndizomwe zimakondedwa, zomwe zimatha kugwira ntchito mokhazikika m'malo otentha kwambiri ndikuwonetsetsa kuti zipangidwa bwino.
(3) Kukhazikika kwa mankhwala, kukana asidi ndi alkali
Pakupanga mankhwala, nthawi zambiri munthu amakumana ndi mankhwala owononga kwambiri monga ma asidi amphamvu ndi alkali. Zida za silicon carbide, zomwe zimakhala ndi kukhazikika kwa mankhwala, zimakhala ngati "chivundikiro cha belu lagolide" patsogolo pa zinthuzi, zomwe zimapangitsa kuti zisawonongeke ndi dzimbiri. Izi zimapangitsa kuti zikhale ndi gawo lofunika kwambiri popanga zida zamakemikolo, monga mapaipi osagwira dzimbiri, ma valve, mapampu, ndi zina, zomwe zimatha kupirira kuwonongeka kwa zinthu zamakemikolo ndikuwonetsetsa kuti kupanga mankhwala kuli kotetezeka komanso kokhazikika.

2, "Ntchito" yazoumbaumba za silicon carbide
（1） Makampani opanga makina: 'chitsanzo cha ntchito' cholimba komanso chosawonongeka
Pakukonza makina, zida zosiyanasiyana zodulira, mabearing, mphete zotsekera ndi zinthu zina ziyenera kupirira katundu wambiri ndi kuwonongeka komwe kumachitika chifukwa cha kuyenda mwachangu. Kuuma kwambiri ndi mphamvu ya silicon carbide ceramics zimapangitsa kuti zikhale zinthu zabwino kwambiri pazinthu izi. Zida zodulira zopangidwa ndi silicon carbide ceramics zimatha kusintha kwambiri kulondola kwa makina ndi moyo wa zida, ndikuchepetsa ndalama zopangira; mabearing ndi mphete zotsekera za Silicon carbide ceramic ali ndi kukana bwino kuvala ndi magwiridwe antchito otsekera, zomwe zimatha kugwira ntchito bwino m'malo ovuta ogwirira ntchito, kuchepetsa kulephera kwa zida, ndikuwonjezera magwiridwe antchito.
（2） Kuchotsa sulfur ku chilengedwe: "mtsogoleri wobiriwira" pochepetsa kuipitsa chilengedwe
Mu ndondomeko yochotsa sulfurization m'mafakitale, zida ziyenera kuyikidwa pa slurry yamphamvu ya acidic desulfurization kwa nthawi yayitali, ndipo zipangizo wamba zimawonongeka mosavuta. Silicon carbide ceramics, yokhala ndi kukhazikika kwabwino kwa mankhwala, sizisintha m'malo okhala ndi acidity ndipo zimatha kukana kuwonongeka kwa slurry ya desulfurization; Nthawi yomweyo, kuuma kwake kwakukulu komanso kukana kuvala kumatha kusunga umphumphu wa zigawo ngakhale zitakhala kuti zawonongeka ndi tinthu tolimba mu slurry. Zigawo monga ma nozzles a desulfurization ndi mapaipi opangidwa ndi silicon carbide ceramics sizimangowonjezera nthawi yawo yogwirira ntchito ndikuchepetsa kutayika kwa nthawi yogwira ntchito komwe kumachitika chifukwa chosinthidwa pafupipafupi, komanso zimawonetsetsa kuti desulfurization ikuyenda bwino, zomwe zimathandiza kupanga mafakitale kupita patsogolo bwino panjira yopita ku miyezo yachilengedwe.
(3) Makampani opanga mankhwala: 'chitetezo choteteza' chosagwira dzimbiri
Pakupanga mankhwala, zida ziyenera kukhudzana pafupipafupi ndi zinthu zosiyanasiyana zowononga kwambiri. Kukhazikika kwabwino kwa mankhwala a silicon carbide ceramics kumawathandiza kuti asawonongeke ndi mankhwala awa. Pazida zamankhwala, kugwiritsa ntchito silicon carbide ceramics pazinthu zofunika monga mapampu, ma valve, ndi mapaipi kumatha kutsimikizira kuti zidazi zikugwira ntchito bwino kwa nthawi yayitali m'malo ovuta a mankhwala, kuchepetsa ndalama zosamalira ndi kusintha zida, ndikuwonjezera chitetezo ndi kudalirika kwa kupanga mankhwala.
3, 'Tsogolo labwino' lazoumbaumba za silicon carbide
Ndi kupita patsogolo kosalekeza ndi chitukuko cha ukadaulo, mwayi wogwiritsa ntchito ziwiya za silicon carbide udzakhala wokulirapo. Kumbali imodzi, ndi kusintha kosalekeza komanso luso lokonzekera ukadaulo, mtengo wopanga ziwiya za silicon carbide ukuyembekezeka kuchepetsedwa kwambiri, zomwe zimapangitsa kuti zigwiritsidwe ntchito m'magawo ambiri; Kumbali ina, ukadaulo wophatikizana wa ziwiya za silicon carbide ndi zipangizo zina ukukulirakulira nthawi zonse. Mwa kuphatikiza ziwiya za silicon carbide ndi zipangizo zina, zipangizo zophatikizana zokhala ndi makhalidwe abwino kwambiri zitha kupangidwa kuti zikwaniritse zosowa zosiyanasiyana zogwiritsira ntchito.
Shandong Zhongpeng, monga kampani yodziwika bwino popanga zoumba za silicon carbide, yadzipereka kufufuza ndikupanga zinthu zapamwamba kwambiri za silicon carbide ceramic, nthawi zonse imayang'ana momwe zoumba za silicon carbide zimagwiritsidwira ntchito m'magawo osiyanasiyana. Tikukhulupirira kuti zoumba za silicon carbide, "ngwazi yayikulu" yamakampani opanga zinthu, zipanga zodabwitsa zambiri pakukula kwaukadaulo ndi kupanga mafakitale mtsogolo, ndikupereka zopereka zazikulu pakupititsa patsogolo kwa anthu.
