Mbali
Zirconia fiber ndi mtundu wa polycrystalline refractory fiber material.Kachulukidwe wachibale ndi 5.6 ~ 6.9.Ili ndi kukhazikika kwamankhwala abwino komanso kukana kwa okosijeni, kutsika kwamafuta, kukana kwamphamvu, komanso kusakhazikika.Chifukwa cha kusungunuka kwakukulu, makutidwe ndi okosijeni ndi makhalidwe ena a kutentha kwa ZrO2, ZrO2 CHIKWANGWANI chimakhala ndi kutentha kwapamwamba kwa utumiki kuposa ulusi wina wotsutsa monga alumina CHIKWANGWANI, mullite CHIKWANGWANI, aluminium silicate CHIKWANGWANI, etc. Zirconia CHIKWANGWANI ntchito kwa nthawi yaitali. mu ultra-high kutentha oxidation mpweya pamwamba 1500 ℃.Kutentha kwakukulu kogwiritsa ntchito mpaka 2200 ℃, ndipo ngakhale pa 2500 ℃, kumatha kukhalabe ndi mawonekedwe athunthu, ndipo kumakhala ndi zinthu zokhazikika zotentha kwambiri, kukana dzimbiri, kukana makutidwe ndi okosijeni, kukana kutenthedwa kwamafuta, kusasunthika, komanso kuipitsidwa. .Pakali pano ndi chida chapamwamba kwambiri padziko lonse lapansi cha refractory fiber.
Kugwiritsa ntchito
Zirconia imakhala ndi oxygen ndi zirconium.Amagawidwa makamaka kukhala clinozoite ndi zircon.
Clinozoite ndi kristalo wa monoclinic wokhala ndi chikasu choyera.
Zircon ndi mchere wakuya wa mwala woyaka moto, wokhala ndi chikasu chowala, chofiirira chachikasu, chobiriwira chachikasu ndi mitundu ina, mphamvu yokoka ya 4.6-4.7, kuuma kwa 7.5, kuwala kwachitsulo kolimba, ndipo kungagwiritsidwe ntchito ngati zopangira zopangira glaze.
Amagwiritsidwa ntchito kwambiri popanga zinthu za ceramic za piezoelectric, zoumba tsiku ndi tsiku, zowumitsa ndi njerwa za zirconium, machubu a zirconium ndi crucibles omwe amagwiritsidwa ntchito kusungunula zitsulo zamtengo wapatali.Amagwiritsidwanso ntchito popanga zitsulo ndi zitsulo zopanda chitsulo, galasi la kuwala ndi zirconia fiber.Itha kugwiritsidwa ntchito ngati chida chothandizira kutentha kwambiri.
Zofotokozera
1) makulidwe: 70±10μm Waya awiri: kuposa 0.3mm
Kutsegula: 0.40 ± 0.02mm Kuwerengera kwa Mesh: 32

Kutsegula: 0.40 ± 0.02mm Kuwerengera kwa Mesh: 32
4) makulidwe: 35±10μm Waya awiri: kuposa0.18mm
Kutsegula: 0.18 ± 0.02mm Kuwerengera kwa Mesh: 60
Ubwino
1. Ni mauna pambuyo kupopera mbewu mankhwalawa: palibe mapindikidwe zoonekeratu, warping, kuwonongeka, ❖ kuyanika osagwirizana, etc
2. Zigawo zazikulu za ❖ kuyanika: khola zirconia ❖ kuyanika, yunifolomu mtundu, palibe zotsatira pa ntchito mankhwala;
3. Pambuyo popirira matenthedwe osachepera 100, kuyanika kwabwino kosalekeza kumatha kusungidwa popanda zokutira zoonekeratu kugwa.
4. Kutentha kwa kutentha ndi kutsika kwachangu: 3-8 ° C / min, kutentha kwakukulu 1300 ° C kwa 2h.
