Kodi mudamvapo za pampu ya silicon carbide slurry? N’chifukwa chiyani imatha 'kuluma mafupa olimba'?

Mu kupanga mafakitale, nthawi zonse pamakhala zinthu zina “zovuta kugwiritsa ntchito” zamadzimadzi – monga mchere wosakaniza ndi tinthu ta mkuwa, madzi otayira okhala ndi matope, “matope” amenewa osalala komanso ophwanyika omwe amatha kuphwanyidwa ndi mapampu wamba amadzi pambuyo pa mapampu ochepa okha. Pakadali pano, ndikofunikira kudalira “osewera olimba” apadera –mapampu a slurry a silicon carbide– kukwera pa siteji.
Anthu ena angafunse kuti, kodi pampu yothira madzi si pampu yongotulutsira madzi? Kodi kusiyana kotani pakati pa kuwonjezera mawu atatu akuti 'silicon carbide'? Ndipotu, chinsinsi chili mu zigawo zake za "mtima" - zigawo zoyendera madzi, monga matupi a mapampu, ma impeller, ndi zina zomwe zimalumikizana mwachindunji ndi madzi, zomwe zambiri zimapangidwa ndi zinthu za silicon carbide.
Kodi silicon carbide ndi chiyani? Mwachidule, ndi chinthu chapadera cha ceramic chomwe ndi cholimba komanso chosawonongeka, chokhala ndi kuuma kwachiwiri kuposa diamondi, ndipo chimalimbana ndi kutentha kwambiri komanso dzimbiri. Ngakhale chikakumana ndi slag slag yokhala ndi tinthu takuthwa, chimatha "kupirira kuwonongeka ndi dzimbiri". Zigawo zamadzimadzi zomwe zimadutsa m'mapampu wamba amadzi zimapangidwa ndi chitsulo. Zikakumana ndi slag ya tinthu tating'onoting'ono, zimaphwanyidwa mwachangu m'dzenje ndipo zimafunika kusinthidwa posachedwa; Zigawo zamadzimadzi zomwe zimadutsa m'madzi zopangidwa ndi silicon carbide zili ngati "ma vest osawombera zipolopolo" omwe amaikidwa pa mapampu, zomwe zimatha kukulitsa nthawi yawo yogwira ntchito ndikuchepetsa mavuto okonza ndi kusintha pafupipafupi.

Komabe, pampu ya slurry ya silicon carbide si chinthu chogwiritsidwa ntchito mosasamala, imapangidwa molingana ndi momwe slurry imakhalira. Mwachitsanzo, ngati tinthu tina ta slurry ta slag tili tolimba, ndikofunikira kuti njira yoyendera ikhale yolimba ndikupanga kapangidwe kake bwino, kuti tinthu ta slag tidutse bwino popanda kutsekereza pampu; Slurry ina ya slag imawononga, kotero chithandizo chapadera chidzagwiritsidwa ntchito pamwamba pa silicon carbide kuti iwonjezere kukana kwake dzimbiri.
Masiku ano, kaya ndi kunyamula matope panthawi ya migodi, kukonza matope a ntchentche m'mafakitale opanga magetsi, kapena kunyamula matope owononga m'mabatani amakampani opanga mankhwala, chithunzi cha mapampu a matope a silicon carbide chikuwoneka. Sichofewa ngati mapampu wamba amadzi, ndipo chimagwira ntchito mokhazikika m'mikhalidwe yovutayi yogwirira ntchito, kuthandiza mafakitale kuchepetsa nthawi yogwira ntchito komanso kuchepetsa ndalama zopangira.
Pomaliza, ubwino wa mapampu a silicon carbide slurry uli mu "kuphatikiza kwamphamvu" kwa zipangizo ndi kapangidwe - kugwiritsa ntchito mphamvu za silicon carbide zosatha komanso zosatha dzimbiri kuti athetse vuto la "kusatha" kwa mapampu wamba, zomwe zimapangitsa kuti kunyamula slurry yovuta kukhale kodalirika komanso kopanda nkhawa. Ichi ndichifukwa chake yakhala "wothandizira" wofunikira kwambiri m'mafakitale ambiri omwe amafunikira "ntchito yolimba".
