Kuyang'ana zotchingira zosavala za silicon carbide ceramics: chishango cholimba cha zida zamafakitale

Pakupanga mafakitale amakono, zida nthawi zambiri zimayang'anizana ndi malo ogwirira ntchito movutikira, ndipo kuwonongeka kwakhala chinthu chofunikira kwambiri chomwe chikukhudza kupanga bwino komanso mtengo wake.Silicon carbide ceramic kuvala zosagwira akalowa, monga zinthu zogwira ntchito kwambiri, zikuwonekera pang'onopang'ono ndikupereka mayankho abwino kwambiri osamva kuvala kwa mafakitale ambiri. Lero, tiyeni tifufuze zazitsulo zosavala za silicon carbide ceramics.

1, The 'Superpower' ya silicon carbide ceramics
Silicon carbide (SiC) ceramics ndi zinthu zophatikizika zopangidwa ndi zinthu ziwiri, silicon ndi kaboni. Ngakhale mawonekedwe ake osavuta, ali ndi ntchito yodabwitsa.
1. Kuphulika kwamphamvu: Kulimba kwa zoumba za silicon carbide ndizotsika pang'ono poyerekeza ndi diamondi yovuta kwambiri m'chilengedwe. Izi zikutanthauza kuti imatha kukana kukanda ndi kudula kwa tinthu tating'ono tolimba, ndikusungabe bata m'malo ovala kwambiri, monga kuyika zida zolimba pazida.
2. Kukana kuvala ndi kukana kupanga: Ndi kuuma kwake kopitilira muyeso komanso mawonekedwe apadera a kristalo, zoumba za silicon carbide zimakhala ndi kukana kwamphamvu kwambiri. Pansi pa mavalidwe omwewo, mavalidwe ake ndi otsika kwambiri kuposa zida zachitsulo zachikhalidwe, kukulitsa kwambiri moyo wautumiki wa zida ndikuchepetsa nthawi ndi kutayika kwamitengo komwe kumachitika chifukwa chakusintha kwagawo pafupipafupi.
3. Kukana kutentha kwakukulu: Zoumba za silicon carbide zimakhalanso ndi kutentha kwambiri ndipo zimatha kugwira ntchito mokhazikika kwa nthawi yayitali pa kutentha kwa 1400 ℃ kapena kupitirira apo. Izi zimapangitsa kuti zikhale ndi gawo lofunika kwambiri m'mafakitale otentha kwambiri monga kusungunula zitsulo, mphamvu zamagetsi zamagetsi, ndi zina zotero. Sizidzasokoneza, kuchepetsa kapena kutaya ntchito yake yoyambirira chifukwa cha kutentha kwakukulu.
4. Kukhazikika kwamphamvu kwamankhwala: Kupatulapo zinthu zingapo monga hydrofluoric acid ndi concentrated phosphoric acid, silicon carbide ceramics imakhala ndi mphamvu yolimbana ndi asidi amphamvu kwambiri, maziko amphamvu, ndi zitsulo zosiyanasiyana zosungunuka, ndipo mankhwala awo ndi okhazikika kwambiri. M'mafakitale monga mankhwala ndi petroleum, akuyang'anizana ndi zofalitsa zosiyanasiyana zowononga, zimatha kuteteza zida kuti zisawonongeke ndikuonetsetsa kuti zikupanga bwino.

2, Zochitika zogwiritsira ntchito silicon carbide ceramic kuvala zosagwira akalowa
Kutengera magwiridwe antchito omwe tawatchulawa, silicon carbide ceramic zomangira zosagwira ntchito zakhala zikugwiritsidwa ntchito kwambiri m'mafakitale angapo.
1. Migodi: Panthawi yonyamula miyala yamtengo wapatali, zinthu zina monga kupindika kwa mapaipi ndi chute zimakhala zosavuta kwambiri kugunda mofulumira komanso kukangana ndi tinthu tating'onoting'ono, zomwe zimapangitsa kuti ziwonongeke kwambiri. Mutakhazikitsa silicon carbide ceramic kuvala zosagwira akalowa, kukana kuvala kwa zigawozi kumakhala bwino kwambiri, ndipo moyo wautumiki ukhoza kuwonjezedwa kuchokera miyezi ingapo mpaka zaka zingapo, kuchepetsa nthawi yokonza zida ndikuwongolera magwiridwe antchito.
2. Makampani amagetsi: Kaya ndi makina otulutsa ufa ndi makina ochotsera phulusa la pneumatic yamagetsi otenthetsera, kapena makina osankhidwa a ufa ndi zomangira za mkuntho wa zomera za simenti, onse amakumana ndi kukokoloka kwa fumbi ndi kuvala. Silicon carbide ceramic kuvala chosagwira ntchito, yokhala ndi kukana kwabwino kwambiri, imachepetsa kuchuluka kwa zida, imawonjezera moyo wautumiki wa zida, komanso imachepetsa nthawi yopumira chifukwa cha kulephera kwa zida, kuwonetsetsa kuti mphamvu ndi kupanga simenti zikuyenda bwino.
3. Makampani opanga mankhwala: Kupanga mankhwala kumaphatikizapo zinthu zosiyanasiyana zowononga zinthu monga ma asidi amphamvu ndi ma alkalis, ndipo zida zimathanso kung'ambika mosiyanasiyana pakagwira ntchito. Silicon carbide ceramic kuvala zosagwira zingwe zonse ndi zosagwira dzimbiri komanso zosavala, ndipo zimatha kusinthiratu malo ogwirira ntchito ovutawa, kuwonetsetsa kuti zida zama mankhwala zikuyenda bwino komanso moyenera. Muzochitika monga kupanga batire la lithiamu komwe kumafunikira kuyeretsedwa kwazinthu zapamwamba kwambiri, kumatha kupewanso kuipitsidwa kwachitsulo ndikuonetsetsa kuti zinthu zili bwino.
Silicon carbide ceramic kuvala zosagwira chinsalu chimapereka chitetezo chodalirika cha zida za mafakitale ndi ntchito yake yabwino, kukhala wothandizira wamphamvu m'mafakitale ambiri kuti apititse patsogolo kupanga ndi kuchepetsa ndalama. Ngati kampani yanu ikuyang'anizananso ndi kuwonongeka kwa zida, mutha kusankha kusankha kansalu kosagwirizana ndi silicon carbide ceramic kuti muyambe mutu watsopano wopanga bwino!
