Mu zochitika za mafakitale, migodi, kapena kutumiza mphamvu, pali mtundu wa mapaipi omwe "sakudziwika" chaka chonse koma ali ndi maudindo akuluakulu - nthawi zambiri amanyamula zinthu zoyatsira moto zomwe zimakhala ndi mphamvu zowononga monga mchenga, matope, ufa wa malasha, ndi zina zotero. Mapaipi wamba amatha kuphwanyidwa pakapita nthawi yochepa, zomwe sizimangokhudza momwe ntchito ikuyendera komanso zimayambitsa ngozi.mapaipi osagwira ntchito a silicon carbideCholinga chake ndi kuthetsa vuto la mafakitale, kukhala "woteteza kwambiri" m'malo ovuta oyendera.
Kodi payipi yolimba yosatha ya silicon carbide ndi chiyani?
Mwachidule, mapaipi osatha kutopa a silicon carbide ndi mapaipi onyamulira opangidwa pophatikiza silicon carbide ngati chinthu chachikulu chosatha kutopa ndi mapaipi achitsulo (monga mapaipi achitsulo) kudzera m'njira zapadera.
Wina angafunse kuti, kodi silicon carbide ndi chiyani? Ndi chinthu chopangidwa mwaluso chosakhala chachitsulo chomwe chili ndi kuuma kwakukulu, chachiwiri kwa diamondi. Mapepala ambiri a sandpaper ndi mawilo opukutira omwe timawona m'moyo watsiku ndi tsiku amapangidwa ndi silicon carbide. Kugwiritsa ntchito 'katswiri wosatopa' wotere popanga mkati mwa mapaipi kungapangitse kuti asamavutike kwambiri.
Poyerekeza ndi mapaipi achitsulo wamba ndi mapaipi a miyala yopangidwa ndi miyala, ubwino waukulu wa mapaipi osagwiritsidwa ntchito ndi silicon carbide uli mu "kukonzanso mkati ndi kunja": gawo lamkati la silicon carbide limayang'anira kukana kukokoloka ndi kuwonongeka kwa cholumikizira, pomwe gawo lakunja lachitsulo limatsimikizira mphamvu yonse ndi mphamvu yokakamiza ya chitoliro. Kuphatikiza kwa ziwirizi sikuti kumangothetsa vuto la kukana kuwonongeka, komanso kumaganiziranso chitetezo ndi kudalirika kwa ntchito zamafakitale.
N’chifukwa chiyani imatha ‘kupirira’ malo ovuta?
Kulimba kwa mapaipi osagwira ntchito a silicon carbide makamaka kumachokera ku mawonekedwe a zinthu za silicon carbide zokha:
Kukana kwamphamvu kwambiri kwa kuvala: Monga tanenera kale, silicon carbide ili ndi kuuma kwakukulu, ndipo kuvala kwake pamwamba kumachepa kwambiri chifukwa cha kuwonongeka kwa nthawi yayitali kuchokera ku granular media monga slurry ndi mchenga. Poyerekeza ndi mapaipi wamba achitsulo, nthawi yawo yogwirira ntchito nthawi zambiri imatha kukulitsidwa kangapo kapena kupitirira nthawi khumi, zomwe zimachepetsa kwambiri kuchuluka ndi mtengo wosinthira mapaipi.
Kukana kutentha kwambiri komanso kotsika komanso kukana dzimbiri: Kuwonjezera pa kukana kutopa, silicon carbide imathanso kusintha kutentha kwambiri, ndipo imatha kugwira ntchito bwino m'malo osiyanasiyana kuyambira madigiri Celsius ochepa mpaka madigiri Celsius mazana ambiri. Nthawi yomweyo, imalimbananso bwino ndi zinthu zowononga monga asidi ndi alkali, zomwe zimapangitsa kuti ikhale "yokhoza" m'malo ovuta oyendera m'mafakitale monga mankhwala ndi zitsulo.
Kugwira ntchito bwino kwa mapaipi: Chifukwa cha pamwamba pake posalala pa silicon carbide, kukana kwa njira yoyendera mupaipi kumakhala kochepa, zomwe zimapangitsa kuti isatsekeke mosavuta. Izi sizimangotsimikizira kuti mayendedwe ake ndi okhazikika, komanso zimachepetsa nthawi yogwira ntchito chifukwa choyeretsa mapaipi.
Kodi imasonyeza kuti luso lake ndi lotani?
Ngakhale zikumveka ngati "zaukadaulo", kugwiritsa ntchito mapaipi osagwira ntchito a silicon carbide kuli pafupi kwambiri ndi kupanga ndi moyo wathu:
Mu mafakitale a migodi ndi zitsulo, imagwiritsidwa ntchito kunyamula matope a mchere kuchokera ku migodi ndi zinyalala kuchokera ku kusungunula, ndipo imawonongeka kwambiri kuchokera ku tinthu tating'onoting'ono tomwe timakhala ndi kuchuluka kwakukulu kwa zinthu;
Mu makampani opanga magetsi, ndi njira yofunika kwambiri yotumizira ufa wa malasha m'malo opangira magetsi otentha, kuonetsetsa kuti mafuta a boiler akupezeka bwino;
Mu mafakitale a zipangizo zomangira ndi mankhwala, imatha kunyamula zinthu zopangira simenti, zinthu zopangira mankhwala, ndi zina zotero, kuti ithane ndi kuwonongeka ndi dzimbiri pang'ono kwa zinthu zosiyanasiyana.
Tinganene kuti m'mafakitale aliwonse omwe amafunikira kunyamula zinthu zo ...
