Kusankha koyenera kwa media media opera - zirconia mikanda ndi ntchito zawo
M'munda wamphesa wonyowa kwambiri komanso kubalalitsidwa, zofunikira zogwirira ntchito pogaya media zikuwonjezeka. Makamaka m'mafakitale monga mphamvu zatsopano, zamagetsi, zoumba mwatsatanetsatane ndi zokutira zapamwamba, zofalitsa zachikhalidwe zogaya sizingathenso kukwaniritsa zofunikira zakupera kopitilira muyeso, kuwongolera chiyero ndi kukhathamiritsa kwamphamvu. Panthawiyi, mikanda ya zirconia, monga mtundu watsopano wazitsulo zamakono zogwiritsira ntchito zida za ceramic, pang'onopang'ono zimakhala zofunikira kwambiri pamsika.
Kodi mikanda ya zirconia ndi chiyani?
Mikanda ya Zirconia ndi timizere ting'onoting'ono tomwe timapangidwa kuchokera ku zida zokhazikika za zirconia zokhala ndi mphamvu zambiri, kulimba kwambiri, kachulukidwe kwambiri komanso kukana kuvala bwino. Zopangira zake zazikulu, zirconia, zimakhala ndi kulimba kwabwino komanso kusakhazikika kwamankhwala, zomwe zimathandiza kuti mikanda ya zirconia ikhalebe yokhazikika komanso moyo wautumiki mu kachulukidwe kakang'ono ka mphamvu, kukameta ubweya wambiri komanso makina owoneka bwino kwambiri.
Mitundu yodziwika bwino ya mikanda ya zirconia ndi:
Y-TZP yokhazikika zirconia mikanda: doped ndi yttrium okusayidi, ndi kachulukidwe kwambiri ndi kuuma, oyenera nano-level akupera;
Mikanda ya zirconia ya ZTA: yopangidwa ndi alumina ndi zirconia, yotsika mtengo;
PSZ yokhazikika pang'ono mikanda ya zirconia: kulimba kwambiri, koyenera kugaya kwamphamvu kwambiri kapena njira zoyambira zopera.
Zochita zabwino za mikanda ya zirconia
Chifukwa chomwe mikanda ya zirconia imatha kuwoneka bwino pakati pazambiri zambiri zogaya makamaka chifukwa cha izi:
Kuchulukira kwakukulu (5.8 ~ 6.2 g/cm³): kumabweretsa mphamvu yamphepo yokulirapo komanso kumathandizira kugaya bwino;
Kuuma kwakukulu (kuuma kwa Mohs ≥8): kusakhala kosavuta kuvala, sikungabweretse kuipitsidwa kwa zonyansa kuzinthu zogaya;
Kulimba kwakukulu: kosavuta kuthyola ngakhale pansi pa mphamvu yamphamvu kwambiri, kuonetsetsa kuti kugaya kukhazikika;
Kutsika kovala: kutayika kochepa kwambiri kwa mikanda pa nthawi ya unit, kukulitsa moyo wautumiki;
Malo osalala komanso ozungulira kwambiri: ntchito yosalala, kuchepetsa kuvala kwa zida ndi kugwiritsa ntchito mphamvu.
Ntchito zosiyanasiyana
Mikanda ya Zirconium oxide imatha kugwiritsidwa ntchito kwambiri pazida zosiyanasiyana zonyowa zonyowa (monga mphero zopingasa mchenga, mphero zowawitsa, zopukutira mabasiketi, ndi zina zotero), ndipo ntchito zake zenizeni zikuphatikiza, koma sizimangokhala:
Zida zatsopano zamagetsi: kupera kwa lithiamu iron phosphate, ternary materials, silicon-carbon negative electrode, etc.;
Zoumba zapamwamba kwambiri: zomwe zimagwiritsidwa ntchito pakuwongolera ufa wa aluminium oxide, silicon nitride, silicon carbide, etc.;
Zida zamagetsi zamagetsi: monga ITO conductive glass slurry, MLCC ceramic powder, etc.;
Inki zokutira zapamwamba kwambiri: kubalalitsidwa kofanana kwa inki za UV, zokutira za nano, ndi inki zamagetsi;
Mankhwala ndi chakudya: amagwiritsidwa ntchito pogaya zopanda kuyipitsa mu biopharmaceuticals ndi zakudya zogwira ntchito.
Chidule
Monga sing'anga yapamwamba yopera yomwe imaphatikiza mphamvu zambiri, kuyera kwakukulu ndi kukhazikika kwakukulu, mikanda ya zirconia ikukhala chinthu chofunika kwambiri m'mafakitale osiyanasiyana kuti apititse patsogolo kulondola kwa ufa, kukhazikika kwa kupanga, ndi kukhathamiritsa nyumba zamtengo wapatali. Ndikupita patsogolo kosalekeza kwa kupanga mwatsatanetsatane komanso kupanga zobiriwira, mikanda ya zirconia idzakhala ndi gawo lalikulu pakugwiritsa ntchito mphesa konyowa mtsogolo.
