Khoom Description

Alumina hmoov zoo yog txawv ntawm cov tshuaj txhuas oxide hmoov thiab siab -kub calcined aluminium oxide hmoov. Nws siv tsawg sodium calcined aluminium oxide ua cov khoom siv raw thiab yog tsim los ntawm ntau-theem precision sib tsoo, muab qhab nia, thiab kev ua kom huv. Tag nrho cov txheej txheem tsim khoom yog tsom rau kev tswj cov particle loj faib, cov ntsiab lus sodium, thiab impurity piv.
Alumina hmoov zoo yog nyob rau hauv daim ntawv ntawm dawb xoob hmoov, nrog lub siab melting point, ruaj khov lub cev thiab tshuaj, thiab tsis muaj ntxhiab los yog toxicity. Kev daws qhov tsis zoo ntawm qhov tsis sib xws ntawm qhov loj me, cov ntsiab lus sodium siab, thiab tsis zoo sintering compatibility ntawm zoo tib yam alumina hmoov hauv precision machining. Nws qhov loj me me thiab zoo dispersibility ua rau nws muaj peev xwm sib xyaw nrog lwm cov ntaub ntawv raw hauv cov txheej txheem qhuav lossis ntub dej, kom ntseeg tau qhov sib xws thiab ruaj khov ntawm cov khoom tiav.

Khoom nta ntawm Alumina hmoov zoo

1. Tsawg sodium thiab tsis muaj impurity cov ntsiab lus
Ua los ntawm cov khoom siv uas tsis muaj sodium calcined alumina raw cov ntaub ntawv, cov ntsiab lus sodium oxide yog nruj me ntsis tswj nyob rau hauv ib tug tsawg ntau yam, tsis txhob muaj kev cuam tshuam ntawm sodium impurities rau cov khoom sintering, rwb thaiv tsev, thiab siab -kub kev ua tau zoo. Cov ntsiab lus ntawm hlau, silicon, calcium, thiab lwm yam kev puas tsuaj impurities kuj raug txo kom tsawg los xyuas kom meej lub purity ntawm cov khoom.
2. Ultra nplua thiab tsis zoo particle loj
Tom qab kev sib tsoo thiab ntau- theem kev muab qhab nia, qhov kev faib tawm qhov loj me yog qhov sib xyaw ua ke thiab sib xws, tsis muaj cov khoom loj lossis pawg.
3. High melting point thiab siab mechanical zog
Nws muaj lub siab melting point thiab zoo heev mechanical zog thiab hardness. Cov khoom tsim los ntawm cov hmoov no muaj zog tiv thaiv, hnav tsis kam, thiab kev cuam tshuam tsis kam, thiab tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ua haujlwm hnyav.
4. High hluav taws xob rwb thaiv tsev thiab thermal conductivity
Nws muaj lub siab ntim resistivity thiab zoo heev thermal conductivity, uas tuaj yeem ua cua sov sai sai thaum ua kom muaj kev nyab xeeb hluav taws xob.

daim ntawv thov

1. Cov khoom siv hluav taws xob thiab cov khoom siv
Raws li cov khoom siv raw rau hluav taws xob ceramics, insulating substrates, thiab cov khoom siv hluav taws xob.
