Ibiranga birindwi biranga Alumina Poroseri

1.Imbaraga zikomeye.Imbaraga zihindagurika zaalumina farforine ibicuruzwa byacumuyeni 250MPa, naho ibicuruzwa bishyushye bigera kuri 500MPa.Isuku ya alumina, niko imbaraga nyinshi.Imbaraga zirashobora kugumaho kugeza kuri 900 ° C mubushyuhe bwinshi.Gukoresha imbaraga za mashini zaalumina farfor, irashobora gukorwa mubice byubukanishi nka farashi.Mohs gukomera kwaalumina ceramicsirashobora kugera kuri 9, wongeyeho ifite imbaraga zo kwihanganira kwambara, bityo ikoreshwa cyane mubikoresho byo gukora, imipira yumupira, gusya ibiziga, imisumari ya ceramic, imisumari, nibindi, muribyo bikoresho bya alumina ceramic nibikoresho byinganda bikoreshwa cyane.

2.Kurwanya cyane, imikorere myiza yo gukwirakwiza amashanyarazi.Icyumba cy'ubushyuhe bwo kurwanyaalumina farforni 1015 Ω · cm, kandi imbaraga zo gukumira ni 15kV / mm.Ukoresheje insulasiyo n'imbaraga zayo, irashobora gukorwa muri substrate, sock, plug spark, shell circuit nibindi.

3.Ubukomere bukabije.Alumina farformohs ubukana bwa 9, hiyongereyeho kwihanganira kwambara neza, kubwibyo bikoreshwa cyane mubikoresho byo gukora, gusya ibiziga, ibikoresho byo gusya, gushushanya bipfa, gukuramo bipfa, kwishyiriraho nibindi.Ibisobanuro bihanitse birashobora kugerwaho kumuvuduko mwinshi mugihe utunganya moteri yimodoka nibice byindege ukoresheje ibikoresho bya alumina ceramic.

4.Icyerekezo kinini cyo gushonga.Kurwanya ruswa ya farumasi ya alumina ni 2050 and, kandi ifite imbaraga zo kurwanya Be, Sr, Ni, Al, V, Ta, Mn, Fe, Co nibindi byuma bishongeshejwe.Irwanya kandi cyane isuri ya NaOH, ikirahure na slag.Ntabwo ikorana na Si, P, Sb na Bi mukirere cya inert.Kubwibyo, irashobora gukoreshwa nkibikoresho byangiritse, umuyoboro w itanura, insinga yikirahure ishushanya ingenzi, umupira wuzuye, fibre, igifuniko gikingira thermocouple, nibindi.

5. Imiterere ihamye yimiti.Sulfide nyinshi, fosifate, arsenide, chloride, nitride, bromide, iyode, okiside, na sulfurike, hydrochloric, nitric, na hydrofluoric aside ntabwo ikorana na alumina.Kubwibyo, alumina irashobora gukorwa mubyuma byera no gukura kwa kristu imwe rukomeye, ingingo zabantu, amagufwa yubukorikori nibindi.

6. Ibikoresho byiza.Alumina farforIrashobora gukorwa mubintu bisobanutse (parufe ya alumina ibonerana), itara rya sodium ya vapor, imurikagurisha rya microwave, idirishya rya infragre, ibintu bya laser oscillation, nibindi.

7.Icyerekezo cyonyine.Alumina farforirashobora gukoreshwa nkibikoresho byizuba hamwe nibikoresho bya batiri.
