Qhov zoo ntawm 95% alumina ceramics

1. Dab tsi yog alumina ceramics:

Alumina ceramics yog cov khoom siv ceramic nrog alumina (Al2O3) ua lub cev tseem ceeb, siv nyob rau hauv tuab zaj duab xis kev sib koom ua ke. Alumina ceramics muaj cov coj zoo, lub zog ntawm lub zog thiab siab kub. Nws yuav tsum nco ntsoov tias kev tu ultrasonic yog qhov yuav tsum tau ua. Alumina ceramics yog hom ntawm ceramics uas muaj qhov siv ntau. Vim tias nws cov khoom muaj zog, nws tau dhau los ua ntau dua thiab siv dav hauv zej zog niaj hnub kom tau raws li qhov xav tau ntawm kev siv txhua hnub thiab cov khoom tshwj xeeb.

2. Kev faib tawm ntawm alumina ceramics:

Alumina ceramics tau muab faib ua hom siab-siab huv thiab ntau hom. High-purity alumina ceramics yog cov khoom siv ceramic nrog cov ntsiab lus Al2O3 ntau dua 99.9%. Vim tias lawv qhov kub siab sintering kub npaum li 1650-1990 ℃, thiab qhov kis tau tus mob yoj yog 1 txog 6 μm, lawv feem ntau yog ua los ntawm iav iav los hloov platinum ntsia saum ntoo; siv nws lub teeb xa hluav taws xob Nws tuaj yeem siv ua sodium sodium tube raj thiab tuaj yeem siv ua hluav taws xob sib xyaw ua ke thiab cov khoom siv hluav taws xob ntau hauv cov khoom siv hluav taws xob.

Ordinary alumina ceramics tau muab faib ua 99 cov pob zeb yas, 95 plooj (veneers), 92 plooj (veneers), 85 cov plooj (veneers) thiab lwm yam raws li Al2O3 ntsiab lus sib txawv. Qee lub sij hawm cov neeg uas muaj 80% lossis 75% Al2O3 cov ntsiab lus kuj tseem cais raws li dog dig alumina ceramic series. Ntawm lawv, 99 alumina cov khoom siv plooj (porcelain) yog siv los ua qhov kub siab ua kom tawg, cov hluav taws xob refractory lub rhawv thiab cov ntaub ntawv hnav tshwj xeeb, xws li cov kabmob ceramic, cov ntsaws ruaj ruaj ceramic thiab cov dej dej valve 95 alumina cov plooj (porcelain) feem ntau yog siv los ua cov khoom tiv thaiv corrosion thiab hnav-resistant; 85 cov plooj (porcelain) Vim tias nws feem ntau xyaw nrog qee cov talc, cov khoom siv hluav taws xob thiab lub zog ntawm lub tshuab tau zoo tuaj, thiab nws tuaj yeem raug ntim nrog hlau xws li molybdenum, niobium, thiab tantalum, thiab qee qhov siv los ua cov tshuab nqus hluav taws xob.

Qhov zoo ntawm 95% alumina ceramics:

1. Lub hardness ntawm 195% alumina ceramics: nws cov hardness yog HRA80-90, uas yog thib ob rau pob zeb diamond thiab deb tshaj qhov hnav tsis kam ntawm hnav-resistant hlau thiab stainless hlau.

2.95% alumina ceramics muaj zoo hnav tsis kam: nws hnav tsis kam yog sib npaug rau 266 lub sijhawm uas ntawm manganese steel thiab 171.5 npaug ntawm cov muaj siab chromium nrum hlau.

3. Lub 95% alumina ceramic yog lub teeb nyob hauv qhov hnyav: nws cov ntom ntom yog 3.6g / cm3, uas tsuas yog ib nrab ntawm cov hlau, uas tuaj yeem txo cov cuab yeej ntsaws.

4. 95% ntawm alumina ceramics sib raug zoo thiab muaj cua sov tsis kam: cov ntaub coj los tiv thaiv cov nplais yog glued rau sab hauv phab ntsa sab hauv ntawm cov khoom siv los ntawm tshav kub-muaj zog kua nplaum. Cov nplaum tuaj yeem khiav ntev ntev li ntawm 350 ° C yam tsis muaj kev laus, thiab cov nplaum inorganic ntawm cov khoom siv cement muaj qhov tsis kam ntawm 750 ° C. Qhov ntsuas kub tsis kam thiab qhov ntsuas qhov ua tau zoo ntawm kev nplaum yog deb deb hauv Suav teb.

5. 95% ntawm alumina ceramics yog qhov yooj yim rau kev txhim kho: Lub tuam txhab muaj cov kws txawj thiab cov neeg ua haujlwm tsim ua lub luag haujlwm rau lub installation ntawm ntau yam khoom.

6. 95% ntawm alumina ceramics muaj ntau qhov kev siv: dav siv hauv cov thee, hlau, mining, tshuaj lom neeg, cement, chaw nres nkoj thiab lwm yam lag luam' tshuab siv roj, tsheb thauj mus los, sib tsoo tshuab, tshem tawm tshauv, tshem plua plav thiab txhua yam khoom siv cav piv txwv, hauv cov kab ke, cov khoom sib txawv tuaj yeem xaiv raws li kev xav tau sib txawv.
