Mitundu ya ceramics zamakampani

Zoumba zamafakitale ndi mtundu wa zoumba zabwino, zomwe zimatha kupanga makina, matenthedwe, mankhwala ndi ntchito zina zomwe zikugwiritsidwa ntchito. Zoumba zamafakitale zimakhala ndi maubwino angapo monga kukana kutentha kwambiri, kukana kwa dzimbiri, kukana kuvala komanso kukana kukokoloka.

Pali mitundu yambiri ya zirconia zadothi zoumba mafakitale, zomwe zimagawidwa m'magulu otsatirawa malinga ndi gulu la zipangizo:

1. Zoumba za okosidi: makamaka alumina zadothi, zirconia ceramics, mullite ceramics, etc.;

2. Zoumba zadothi: makamaka zoumba za silicon, zoumba za aluminiyamu, zoumba za boroni, ndi zina zotero;

3. Carbide ceramics: makamaka silicon carbide ceramics, titanium carbide ceramics, boron carbide ceramics, etc.;

4. Boride ceramics: makamaka titaniyamu boride ceramics, zirconium boride ceramics, etc.

Ntchito za zitsulo zamafakitale zimakhala ndi mphamvu zawo ndipo zimagwiritsidwa ntchito kwambiri, monga kugwiritsa ntchito kuuma kwapamwamba ndi zoumba zapamwamba zowonongeka kuti zipange zida zamakina, zisindikizo, zida zodulira ndi zipangizo zina, komanso kugwiritsa ntchito kukana kwapamwamba kwambiri, mphamvu zambiri zoumba zolimba kwambiri zopangira magalimoto Gwiritsani ntchito zida zovala- zosamva, zopepuka, kutentha- zosagwira ndi kutentha-zigawo zotchingira, zotchingira mpweya, nsonga za pistoni, zoyikapo, ndi zina zambiri, ndikugwiritsa ntchito zoumba zomwe zimakhala ndi dzimbiri- zosagwira komanso zimakhala ndi kukhazikika kwamankhwala polumikizana ndi michere yachilengedwe kuti ipangitse crucibles ndi zosinthira kutentha kwazitsulo zosungunulira zitsulo, Zachilengedwe monga zolumikizira utoto wopanga mano, ndi zina zambiri, zimagwiritsa ntchito zida zapadera zomwe zimagwira ndi kuyamwa ma neutroni kuti apange zida zosiyanasiyana zanyukiliya. zomangamanga, etc.

Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo, zotsogola zachitika pakupititsa patsogolo zoumba zamafakitale, makamaka kafukufuku ndi chitukuko chamitundu yambiri yamagulu a ceramic ndi nano-ceramics. Pankhani ya kafukufuku wamitundu yambiri yamagulu a ceramic, zida zadothi zotsogola zapangidwa kuchokera pagawo loyambirira - gawo ndi mawonekedwe apamwamba - chiyero kupita kumagulu angapo, ndikupanga okha-zingwe zomangirira zadothi kapena krustalo - zowumbika pamwamba zophatikizika zadothi, zowuma zowoneka bwino. ndi nano-composite ceramics. Kuchita bwino Imathetsa zovuta zaukadaulo za brittleness, kudalirika kochepa, mphamvu zosakwanira kutentha komanso kusakwanira kwa single-zigawo zapamwamba za ceramic.

Pankhani ya kafukufuku wa nano-ceramics, zoumba zamafakitale zikukula kuchokera pamlingo wa micron kupita ku nano-level, ndipo njira zambiri zatsopano zopangira nano-ceramic powders zapangidwa, monga mpweya wamankhwala, chitsulo-organic compound solution, ndi mankhwala. gas gawo reaction. Kupanga kumapereka mikhalidwe yabwino.

Ntchitoyi ikuwonetsa kuti kuyengedwa kwa nano-njere za ceramic kumatha kupeza zinthu zopanda chilema kapena zolakwika, kuwongolera kwambiri zida zoyambira zadothi, komanso kuwoneka zatsopano, kupangitsa kuti malo a ceramic achuluke. Chifukwa chake, nano-ceramics yakhala phunziro latsopano lofufuzira ndipo yalandira chidwi kwambiri. Zikuyembekezeka kuti tsogolo lidzakhala nthawi yaukadaulo wapamwamba kwambiri, womwe udzakhala ndi gawo lofunikira kwambiri mu sayansi yamakono ndiukadaulo komanso makampani amakono.
