'Wosewera wolimba' mumakampani opanga mapaipi osatha: Nchifukwa chiyani chitoliro chosatha cha silicon carbide chimatuluka m'bwalo?

M'malo opangira mafakitale, mapaipi ndiye "njira yopezera moyo" wonyamulira zinthu. Komabe, poyang'anizana ndi kuwonongeka kwa zinthu zolimba monga mchenga, matope, ndi zinyalala, mapaipi wamba nthawi zambiri amataya madzi ndi kuwonongeka mkati mwa nthawi yochepa. Izi sizimangofunika kuzimitsidwa ndi kusinthidwa pafupipafupi, komanso zitha kubweretsa zoopsa zachitetezo. Pakati pa mapaipi ambiri osatha, mapaipi osatha a silicon carbide akhala chinthu chodziwika bwino m'mafakitale chifukwa cha kukana kwawo kwambiri. Lero, tikambirana za "wosewera wolimba" uyu mumakampani opanga mapaipi.
Anthu ambiri sadziwa bwino za silicon carbide yopangidwa ndi zinthuzi. Mwachidule, ndi chinthu chosapangidwa ndi chitsulo chomwe chili ndi kuuma kwachiwiri kuposa diamondi, ndipo mwachibadwa chimakhala ndi mphamvu "zoletsa kupanga". Chitoliro cholimba chomwe chimapangidwa nacho chili ngati kuyika "zoteteza za diamondi" pa payipi, zomwe zimatha kukana mosavuta kukhudzidwa ndi zinthu zosiyanasiyana zowononga kwambiri.
Poyerekeza ndi mapaipi achitsulo achikhalidwe ndi mapaipi a ceramic, ubwino wamapaipi osagwira ntchito a silicon carbidendi otchuka kwambiri. Choyamba, imakhala ndi mphamvu yolimba yolimbana ndi kuwonongeka. Kaya ikunyamula matope okhala ndi mchenga wa quartz kapena zinyalala zotsalira ndi tinthu tolimba, imatha kusunga mawonekedwe ake pamwamba ndipo imakhala ndi moyo wautali kangapo kuposa mapaipi wamba achitsulo, zomwe zimachepetsa kwambiri kuchuluka ndi mtengo wosinthira mapaipi. Kachiwiri, imakhala ndi mphamvu yolimba yolimbana ndi dzimbiri. Zipangizo zamafakitale nthawi zambiri zimakhala ndi zinthu zowononga monga asidi ndi alkali, ndipo mapaipi wamba amatha kuwononga ndi kukalamba. Komabe, silicon carbide yokha ili ndi mphamvu zokhazikika zamakemikolo ndipo imatha kukana kuwonongeka kwa zinthu zosiyanasiyana za acid ndi alkali, zomwe zimapangitsa kuti ikhale yoyenera malo ovuta ogwirira ntchito.

Kuphatikiza apo, mapaipi osatha kutopa a silicon carbide alinso ndi mawonekedwe abwino - kutentha kwabwino, komwe kumatha kufalitsa kutentha mwachangu ponyamula zinthu zotentha kwambiri, kupewa kusintha kwa mapaipi komwe kumachitika chifukwa cha kutentha kwambiri, komanso kuchepetsa kutayika kwa kutentha, kuchepetsa mphamvu yogwiritsira ntchito popanga. Kuphatikiza apo, kapangidwe kake kakang'ono kamaipangitsa kuti isasiyane kwambiri ndi mapaipi wamba ikayikidwa, popanda kufunikira kusintha zida zina. Ili ndi vuto lochepa poyambira ndipo imatha kusintha mosavuta mapulojekiti atsopano omanga komanso kukonzanso mapaipi akale.
Masiku ano, mapaipi osatha kutopa a silicon carbide akhala akugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga migodi, zitsulo, zamagetsi, ndi uinjiniya wa mankhwala, monga mayendedwe a matope m'migodi, machitidwe ochotsa sulfurization ndi denitrification m'mafakitale amagetsi, komanso mayendedwe a zinyalala m'makampani opanga zitsulo, komwe kupezeka kwawo kumatha kuwoneka. Sikuti zimangothetsa mavuto a mapaipi achikhalidwe omwe amatha kutha ndi dzimbiri, komanso zimathandiza mabizinesi kuchepetsa nthawi yogwira ntchito, kuchepetsa ndalama zokonzera, ndikuwonjezera magwiridwe antchito opangira, kukhala "chida chofunikira kwambiri chothana ndi kutha" m'mafakitale.
Ndi chitukuko chopitilira cha ukadaulo wamafakitale, kugwiritsa ntchito zinthu za silicon carbide kukukulirakulirabe. Tikukhulupirira kuti mtsogolomu, mapaipi osagwira ntchito a silicon carbide adzatulutsa kuwala ndi kutentha m'magawo osiyanasiyana, zomwe zidzateteza kuti ntchito yopanga mafakitale ikhale yokhazikika.
