'Malo amphamvu osatha kutopa' opangidwa ndi mafakitale: mphamvu yolimba ya pampu ya slurry ya silicon carbide

Mu njira yotumizira zinthu m'mafakitale monga migodi, zitsulo, ndi uinjiniya wa mankhwala, mapampu a slurry ndi "oyendetsa" omwe ali ndi udindo wonyamula zinthu monga slurry ndi matope okhala ndi tinthu tolimba. Komabe, mapampu wamba a slurry nthawi zambiri amakhala ndi moyo waufupi ndipo amakhala ofewa akawonongeka kwambiri komanso dzimbiri lamphamvu, pomwe kutuluka kwamapampu a slurry a silicon carbideimathetsa mwachindunji vuto lakale ili.
Ngati gawo lamagetsi ochulukirapo la pampu wamba ndi "mbale ya mpunga ya pulasitiki" yomwe imasweka ikagunda pamalo olimba, ndiye kuti gawo lamagetsi ochulukirapo lopangidwa ndi zinthu za silicon carbide ndi "mbale ya diamondi" yokhala ndi kuuma kwachiwiri kuposa diamondi. Ponyamula zinthu zokhala ndi mchenga, miyala, ndi slag, tinthu tating'onoting'ono tomwe timayenda mwachangu timatsuka thupi la pampu nthawi zonse, koma zigawo za silicon carbide zimatha kukhalabe "zosasunthika", ndi kukana kuwonongeka kopitilira kwa zinthu zachitsulo, zomwe zimakulitsa kwambiri moyo wa pampu ndikuchepetsa vuto loyimitsa ndikusintha ziwalo.

Kuwonjezera pa kukana kutopa, pampu ya silicon carbide slurry imabweranso ndi "anti-corrosion buff". Mafakitale ambiri okhala ndi ma acid ndi alkali amphamvu, ndipo mapampu wamba achitsulo posachedwa adzazimiririka ndi mabowo. Komabe, silicon carbide ili ndi mphamvu zokhazikika zamakemikolo, monga momwe zimakhalira ndi "zoteteza kutopa" pa thupi la pampu. Imatha kugwira zinthu zosiyanasiyana zowononga mofatsa ndipo siidandaulanso ndi ngozi zopanga zomwe zimachitika chifukwa cha kutayikira kwa dzimbiri.
Chofunika kwambiri ndichakuti khoma lamkati la gawo loyenda la pampu ya silicon carbide slurry ndi losalala, zomwe zimapangitsa kuti zinthu zisagwiritsidwe ntchito bwino. Izi sizimangochepetsa kugwiritsa ntchito mphamvu, komanso zimachepetsa kutsekeka ndi kutsekeka kwa tinthu tating'onoting'ono mkati mwa pampu. Ngakhale kuti ndi "yolimba", siili ndi nkhawa komanso ndi yothandiza kugwiritsa ntchito. Muzochitika zomwe zimafuna kunyamula zinthu zolimba kwa nthawi yayitali komanso mwamphamvu, ndi "wantchito wodalirika".
Masiku ano, mapampu a silicon carbide slurry akhala zida zomwe zimakonda kwambiri m'mafakitale chifukwa cha ubwino wawo wowirikiza wa kukana kuwonongeka ndi kukana dzimbiri. Ndi magwiridwe antchito, amapereka chitetezo kwa mabizinesi kuti achepetse ndalama ndikuwonjezera magwiridwe antchito.
