Mchenga woyera wa corundum, ufa woyera wa corundum, corundum wofiirira ndi zina zonyamulira ndi zinthu zofala kwambiri, makamaka ufa woyera wa corundum, womwe ndi chisankho choyamba chopukutira ndi kupukuta. Uli ndi makhalidwe a kristalo imodzi, kuuma kwambiri, kudzinola bwino, komanso ntchito yopukutira ndi kupukuta. Ubwino monga kukweza kwagwiritsidwa ntchito ndikulimbikitsidwa m'mafakitale osiyanasiyana. Ndiye, mungasankhe bwanji popukuta?
Kusankha kowala
Chodulira ndi chinthu chachikulu chomwe chimagwira ntchito yodulira podula. Chimayang'anira mwachindunji ntchito yodulira ndipo ndicho chinthu chofunikira kwambiri kuti gudumu lodulira lipange mphamvu yodulira. Choduliracho chiyenera kukhala cha bulauni corundum chopangidwa ndi Xinli chosatha kutopa. Zogulitsa zake zimakhala zolimba kwambiri, zotsutsana ndi kutentha, zokhazikika pa kutentha komanso zokhazikika pa mankhwala, ndipo ziyeneranso kukhala zolimba kuti zizitha kupirira mphamvu inayake yodulira.
Mfundo yosankhira zinthu mopupuluma
Mukapera zinthu zomwe zili ndi mphamvu yokoka kwambiri, gwiritsani ntchito zopopera za corundum zomwe zili ndi mphamvu yokoka kwambiri. Mukapera zinthu zomwe zili ndi mphamvu yokoka yochepa kuti musankhe zopopera za silicon carbide zofooka.
Kuwonjezera pa kuganizira mphamvu yokoka ya chipangizo chogwirira ntchito, kuuma kwa chipangizo chogwirira ntchito ndiko maziko osankhika posankha zinthu zonyamulira. Kawirikawiri, kuuma kwa chinthu chonyamulira kuyenera kukhala kokwera nthawi 2-4 kuposa kuuma kwa chipangizo chogwirira ntchito. Kupanda kutero, tinthu tonyamulira tomwe tili ndi kuuma kochepa tidzatha kuchotsedwa mwachangu panthawi yodula mwachangu ndikutaya luso lodula, zomwe zipangitsa kuti kulimba kwa gudumu kukhale kochepa kwambiri ndikukhudza magwiridwe antchito odulira, komanso khalidwe lokonza silingatsimikizidwe. Chifukwa chake, kuuma kwa chinthu chogwirira ntchito kukakhala kwakukulu, kuuma kwa chinthu chonyamulira kuyenera kukhala kwakukulu.
Kusankha zinthu zowononga
Kuganiziranso kuyenera kuperekedwa pa momwe mankhwala angagwiritsidwire ntchito mu njira yopukusira. Mu malo opukusira, zinthu zopukusira, zomangira, zinthu zogwirira ntchito, madzi opukusira ndi mpweya zimakhala ndi zotsatirapo za mankhwala zomwe zimachitika mwadzidzidzi chifukwa cha kutentha ndi mphamvu yopukusira. Chitsulo chikagwiritsidwa ntchito, kuwonongeka kwa abrasive kumakhala kofulumira kuposa kwa corundum abrasive popukusira chitsulo. Chifukwa chachikulu cha izi ndi momwe mankhwala amagwirira ntchito mwamphamvu pakati pa silicon carbide abrasive ndi chitsulo.
Kuphatikiza apo, kukhazikika kwa kutentha kwa chopopera kuyeneranso kuganiziridwa posankha chopopera. Mukapera zinthu zina zovuta kugaya, ngozi zina zimachitika pamene malo opopera amakhala ndi kutentha kwambiri.
