M'mafakitale monga migodi, zitsulo, ndi magetsi, mapampu otayira ndi zida zofunika kwambiri zonyamulira zinthu zowononga kwambiri komanso zowononga kwambiri. Ngakhale kuti mapampu achitsulo achikhalidwe ali ndi mphamvu zambiri, nthawi zambiri amakumana ndi mavuto owonongeka mwachangu komanso nthawi yochepa yogwirira ntchito akakumana ndi zovuta zogwirira ntchito. M'zaka zaposachedwa, kugwiritsa ntchito mtundu watsopano wa zinthu -zoumbaumba za silicon carbide– yakweza kulimba ndi kugwira ntchito bwino kwa mapampu a slurry kufika pamlingo watsopano.
1, Silicon carbide ceramics: kuyambira "mano a mafakitale" mpaka kupopera zinthu zogwirira ntchito
Silicon carbide (SiC) imadziwika kuti "dzino la mafakitale", lolimba kwambiri kuposa diamondi koma lopepuka kwambiri kuposa zitsulo. Choyamba, chida ichi chinagwiritsidwa ntchito pogaya mawilo ndi zida zodulira. Pambuyo pake, asayansi adapeza kuti kukana kwake kutopa komanso kukhazikika kwa mankhwala kumatha kuthetsa ululu wa mapampu a slurry:
Yosatopa komanso yosapsa: Kulimba kwake ndi kwachiwiri kuposa diamondi, ndipo imatha kupirira mosavuta kuwonongeka kwa zinthu zomwe zili ndi mchenga, miyala, ndi tinthu tating'onoting'ono;
Kuletsa dzimbiri mwachilengedwe: Kumalimbana kwambiri ndi asidi wamphamvu ndi njira zina zothetsera dzimbiri, kupewa mavuto ofala a dzimbiri a mapampu achitsulo;
Kapangidwe kopepuka: Kuchuluka kwake ndi gawo limodzi mwa magawo atatu okha a chitsulo, zomwe zimachepetsa katundu wa zida ndi kugwiritsa ntchito mphamvu.
2, Ubwino waukulu wa mapampu a ceramic a silicon carbide
1. Kuonjezera nthawi ya moyo ndi kangapo
Mapampu achitsulo achikhalidwe angafunike kusintha ma impeller ndi ma casing a pampu m'miyezi ingapo akamanyamula ma slurry okhwima, pomwe zinthu za silicon carbide zimatha kugwira ntchito mosasunthika kwa zaka zingapo, zomwe zimachepetsa kwambiri nthawi yogwira ntchito komanso kukonza.
2. Chepetsani ndalama zokonzera
Chifukwa cha kuchepa kwa kuwonongeka ndi kung'ambika, nthawi yosinthira zowonjezera yawonjezeka, ndipo zida zadothi sizifunikira chithandizo chambiri choletsa dzimbiri, zomwe zapangitsa kuti ndalama zonse zokonzera zichepetse kwambiri.
3. Kuchita bwino kokhazikika
Kusalala kwa pamwamba pa zinthu zadothi ndi kwakukulu kwambiri, ndipo kugwiritsa ntchito kwa nthawi yayitali sikophweka kupanga mabowo kapena mapindikidwe. Nthawi zonse kumasunga njira yosalala yoyendera kuti tipewe kuwonongeka kwa magwiridwe antchito.
3, Ndi zochitika ziti zomwe zimafuna mapampu a ceramic a silicon carbide kwambiri?
Mavuto aakulu otupa: monga kunyamula zinthu zotsalira m'migodi, kuchiza matope a malasha m'mafakitale otsukira malasha
Malo amphamvu owononga: mayendedwe a asidi amphamvu ndi zinthu zina zamagetsi mumakampani opanga mankhwala, kufalikira kwa slurry ya desulfurization
Malo ofunikira kwambiri pa kuyera: Makhalidwe osagwira ntchito a zinthu zadothi amatha kupewa kuipitsidwa kwa ayoni yachitsulo ya sing'anga
4, Malangizo Oyenera Kutsatira
Ngakhale mapampu a ceramic a silicon carbide ali ndi magwiridwe antchito abwino kwambiri, amafunika kufananizidwa malinga ndi mikhalidwe inayake yogwirira ntchito:
Ndikofunikira kusankha silicon carbide yopangidwa ndi reaction sintered (yokhala ndi mphamvu yolimba yolimbana ndi impact) ngati ultrafine particle medium
Chisamaliro chiyenera kuperekedwa pa kutseka zipangizo ndi kapangidwe kake m'malo otentha kwambiri.
Pewani kugundana kwakukulu panthawi yoyika (zinthu zadothi zimakhala zofooka kuposa chitsulo)
mapeto
Monga "woteteza kukalamba" m'mafakitale, mapampu a silicon carbide ceramic slurry akulimbikitsa kukweza mafakitale achikhalidwe kuti azitha kugwira ntchito bwino komanso kuteteza chilengedwe ndi moyo wautali komanso kugwiritsa ntchito mphamvu zochepa. Kwa mabizinesi, kusankha mtundu woyenera wa pampu wokalamba sikuti kumangotanthauza kusunga ndalama za zida, komanso chitsimikizo chofunikira cha kupitiriza kupanga ndi chitetezo.
Shandong Zhongpengyakhala ikugwira ntchito mwakhama pa zinthu zosatha kwa zaka zoposa khumi, ndipo ili yokonzeka kupereka mayankho a nthawi yayitali pamavuto anu oyendera mafakitale pogwiritsa ntchito ukadaulo watsopano wazinthu.
