Alumina Sib Tsoo Pob
Kev piav qhia txog khoom
Alumina sib tsoo pob,ua nrog txhuas oxide (Al₂O₃) ua lawv cov khoom tseem ceeb thiab siv cov txheej txheem ceramic sintering, yog cov pob ceramic ua haujlwm tshwj xeeb tsim rau kev sib tsoo, tsoo, thiab cov ntaub ntawv dispersing. Lawv yog ib qho ntawm cov khoom siv sib tsoo feem ntau siv hauv kev sib tsoo kev lag luam (xws li ceramics, coatings, thiab minerals).
Cov pob sib tsoo alumina raug faib ua peb hom raws li lawv cov alumina: pob nruab nrab-aluminium (60%-65%), pob nruab nrab-siab-aluminium (75%-80%), thiab pob siab-aluminium (saum toj no 90%). Cov pob siab-aluminium raug muab faib ua 90-ceramic, 92-ceramic, 95-ceramic, thiab 99-ceramic qib, nrog rau 92-ceramic yog qhov siv dav tshaj plaws vim nws qhov kev ua tau zoo tshaj plaws. Cov pob sib tsoo no muaj qhov nyuaj siab (Mohs hardness ntawm 9), qhov ceev siab (saum toj no 3.6g / cm³), kev hnav thiab kev tiv thaiv corrosion, thiab kev tiv thaiv kub siab (1600 ° C), ua rau lawv tsim nyog rau kev sib tsoo zoo ntawm cov iav ceramic, cov khoom siv tshuaj lom neeg, thiab cov hlau minerals.
Nta:
Kev Nyuaj Siab thiab Kev Tiv Thaiv Kev Hnav Muaj Zog:Mohs hardness ncav cuag 9 (ze li pob zeb diamond), nrog rau qhov hnav tsawg (<0.03%/1,000 teev rau cov qauv siab-purity). Nws tiv taus brittleness thiab cov khib nyiab thaum lub sijhawm sib tsoo ntev, ua rau lub neej ua haujlwm ntev.
Kev Ceev Ceev thiab Kev Sib Tsoo Siab:Nrog rau qhov ceev ntawm 3.6-3.9 g / cm³, nws muab cov kev cuam tshuam muaj zog thiab cov zog shear thaum lub sijhawm sib tsoo, sai sai refining cov ntaub ntawv mus rau qib micron, nrog rau kev ua haujlwm zoo dua 20% -30% dua li cov pob txhuas nruab nrab thiab qis.
Cov Khoom Uas Tsis Muaj Peev Xwm Thiab Kev Ruaj Ntseg Tshuaj:Cov qauv uas muaj cov khoom huv siab muaj tsawg dua 1% ntawm cov khoom tsis huv (xws li Fe₂O₃), tiv thaiv kev ua qias tuaj ntawm cov khoom siv. Tiv taus feem ntau cov kua qaub thiab alkalis (tshwj tsis yog cov kua qaub muaj zog thiab alkalis), kub siab (saum toj no 800 ° C), thiab haum rau ntau yam kev sib tsoo.
Qhov Loj thiab Kev Sib Xws:Muaj cov kab uas hla ntawm 0.3 txog 20 hli, lub pob tuaj yeem siv rau hauv ib qho lossis sib xyaw, sib xws nrog cov tshuab sib tsoo pob, cov tshuab xuab zeb, thiab lwm yam khoom siv, ua tau raws li txhua yam kev xav tau los ntawm kev sib tsoo ntxhib mus rau kev sib tsoo zoo.
