Polowa m'dziko lamakono la mafakitale, munthu amatha kuona kupezeka kwa zinthu zapadera - sizili zowala ngati zitsulo kapena zopepuka ngati pulasitiki, koma zimathandiza mwakachetechete kugwira ntchito kwa mafakitale amakono. Uwu ndi banja la zoumba za mafakitale, gulu la zinthu zopanda organic zomwe sizili zachitsulo zomwe zimadziwika ndi makhalidwe awo apadera.
I. "Anthu otchuka" a m'banja la zoumbaumba zamafakitale
Pakati pa banja la zoumba za mafakitale, pali mamembala angapo omwe amasiyana kwambiri: Zoumba za alumina zili ngati mchimwene wake wamkulu wodalirika, zomwe zimadalira kutenthetsa bwino komanso kukana dzimbiri, zomwe zimagwira ntchito yofunika kwambiri pazida zamagetsi ndi zida zamakemikolo; Zoumba za silicon nitride zili ngati othamanga opepuka, zomwe zimakhala ndi kuuma kwa zoumba zadothi komanso kulimba kwa zitsulo, zomwe zikuwonetsa magwiridwe antchito abwino kwambiri mu mabearing ndi zida zodulira; Zoumba za zirconia zili ngati mafashoni, osati zokhala ndi kuwala ngati ngale kokha komanso zokhala ndi ukadaulo wakuda wa "kusintha kwa gawo", zomwe zimakondedwa kwambiri mu mano obisika komanso zigawo zolondola.
II.Zoumbaumba za silicon carbide: Msilikali wodziwika bwino m'munda wa mafakitale
Pakati pa banjali, zoumba za silicon carbide zitha kuonedwa ngati msilikali weniweni. Choumba chapadera ichi chopangidwa ndi zinthu za silicon ndi carbon chinapangidwa koyamba ndi anthu mu 1905 ndipo chakhala chikuswa mbiri ya magwiridwe antchito a zipangizo zamafakitale. Chili ngati chishango chopangidwa ndi diamondi, chokhala ndi kuuma kwa Mohs mpaka 9.5, chachiwiri kwa diamondi yokha; chili ngati zida zopangidwa ndi njerwa zosalimba, zomwe zimatha kupirira kutentha kwa 1350℃.
Mu malo ochitira zitsulo, zida za silicon carbide zopangidwa ndi ziwiya za kilnware zimathandiza kuzimitsa zitsulo; m'mapaipi a mankhwala, zimasanduka choteteza chosagwira dzimbiri, zomwe zimawonjezera moyo wa mapaipi; pamizere yopanga ma semiconductor, ndi chisankho chabwino kwambiri chogwiritsira ntchito molondola; chodabwitsa kwambiri n'chakuti, chinthu cholemera ichi ndi chowongolera kutentha chabwino kwambiri, chomwe chimachipangitsa kuti chipeze malo ake pantchito yochotsa kutentha kwamagetsi.
III. Kusintha ndi kubadwanso kwatsopano komwe kumabwera chifukwa cha ukadaulo
Ukadaulo wamakono wapatsa zinthu za silicon carbide moyo watsopano. Kudzera mu ukadaulo wa nanomodification, asayansi awonjezera kulimba kwake; pogwiritsa ntchito ukadaulo wosindikiza wa 3D, ziwalo zovuta zofanana ndi ntchito zaluso zitha kupangidwa. Mu labotale ya kampani yathu, mainjiniya akuphunzira njira zoyeretsera zinthu za silicon carbide, pogwiritsa ntchito ukadaulo wapamwamba woyeretsera zinthu kuti akwaniritse zofunikira zosiyanasiyana za makasitomala ndikuwongolera nthawi zonse magwiridwe antchito a zinthu za silicon carbide ceramic, zomwe zimawathandiza kuti azolowere mikhalidwe yovuta yogwirira ntchito.
Kuchokera ku mafakitale achikhalidwe mpaka ukadaulo wamakono, zoumba za mafakitale zikulemba nthano yatsopano. Monga wopereka chithandizo chaukadaulo wodziwa bwino ntchito zoumba za silicon carbide, nthawi zonse timadzipereka kupereka mayankho okonzedwa mwamakonda. Kaya ndi kukonza ziwalo zapadera zokhala ndi mawonekedwe apadera kapena kapangidwe ka mayankho ogwiritsira ntchito pamavuto ogwirira ntchito, tingapeze thandizo la akatswiri apa.
