Magwiridwe ndi mawonekedwe a zirconium corundum njerwa zopangira

Zirconium corundum njerwa zaumbali Amapangidwa kuchokera ku aluminium ya mafakitale ndi mchenga wa zircon. Malinga ndi momwe amapangidwira, njerwa za zirconium corundum zitha kugawidwa mu njerwa za zirconium corundum ndi sintered zirconium corundum njerwa.

Wopanga njerwa za Henan, wopanga mpira wotsutsa, njerwa yopepuka, Zhengzhou Huaxin Kutentha Kwambiri Co., Ltd.

Njerwa za zirconium corundum zimatchedwa njerwa zoyera zachitsulo, zotchedwanso corundum clinoptilolite njerwa. Mankhwala akuluakulu ndi 350% ～ 70% Al2O, 220% ～ 40% ZrO, ndipo enawo ndi SiO2. Zida zazikuluzikulu zamchere ndi zircon (ZrO2), corundum (α-Al2O3) ndi gawo lamagalasi. Makristoni a Zircon amapanga mafupa a njerwa. Zirconia imakhala ndi malo osungunuka kwambiri (2715 ° C) komanso kukhazikika kwamankhwala. Zircon imawononga kwambiri media acidic ndi zamchere, makamaka magalasi osungunuka.

Njerwa zosakanizidwa zirconium corundum zimagwiritsidwa ntchito pamavumba agalasi ndi ng’anjo ina yamafuta. Magalasi osungunulira ng’anjo omwe amagwiritsidwa ntchito mu galasi losungunuka ndi magalasi akuphatikizira khoma lakumtunda, kabotolo kakang’ono kotentha, kabowo kakang’ono kotentha, lilime lamanja ndi khoma la m’mawere. Nkhani zotsatirazi ziyenera kusamalidwa mukamagwiritsa ntchito njerwa za zirconia corundum.

Kusintha kosasintha pakukula kwamatenthedwe. Kukula kwa njerwa ya zirconia corundum yosakanikirana kumawonetsa gawo lachilendo pafupi ndi 1000 ℃. Zosintha zosinthika zimachitika mkati mwa Zr02 crystal, ndipo voliyumu imasintha kwambiri. Chifukwa chake, njerwa zomwe zili ndi ZrO2 siziyenera kugwiritsidwa ntchito m’malo omwe kutentha kumasinthasintha mozungulira 1000 ° C. Mu uvuni, kutentha kumasintha pakati pa 900 ～ 1150 ℃ sayenera kukhala yayikulu kwambiri, nthawi zambiri sayenera kupitirira 15 ℃ / h, ndipo kutentha kuyenera kukwezedwa pang’onopang’ono. Malo ena ayenera kutetezedwa ku mphepo yozizira, ndipo njerwa zina zigwiritsidwe ntchito kuti zisawonongeke.

② Kudula. Pakutsanulira, mabowo ochepera nthawi zambiri amawoneka, thupi la njerwa limakhala ndi ma pores ambiri, ndipo kuuma kumakhala kovuta. Chifukwa chake, khoma la galasi losungunuka likamangidwa, malo ocheperako adzayamba kulowera mbali yamoto. Ngati chipata chimayang’ana panja, pomwe thupi la njerwa lidakokoloka mpaka kochepa kwambiri, limadzetsa ngozi zapa magalasi. Amagwiritsidwa ntchito kumtunda kwamoto wamoto kwambiri, wokhala ndi moyo wautali, ndipo palibe vuto la kuthawa kwa magalasi. Chifukwa chake, doko loponyera limagwiritsidwa ntchito panja kuti likulitse moyo wautumiki.

③ Zolemba. Pamene njerwa ya zirconia corundum ikulumikizana ndi njerwa yadothi, eutectic idzawonekera pa 1300 ℃. Chifukwa chake, posankha zida zopangira zinthu, zochitika zazikulu za eutectic zazida ziwirizi ziyenera kupewedwa.

Sintered zirconium corundum njerwa amatchedwanso ceramic womangidwa zotayidwa pakachitsulo zirconium njerwa. Poyerekeza ndi njerwa za zirconium corundum, sintered zirconium corundum njerwa zili ndi mankhwala ofanana, koma zili ndi mwayi wopanda kaboni, gawo lotsika lagalasi, kapangidwe ka yunifolomu, palibe kuchepa, kukhazikika kwamphamvu kwamadzimadzi, kukana dzimbiri, ndi zina zambiri.
