Tshuaj Muaj Tshuaj
Lub ntsiab tivthaiv yog txhuas oxide (al₂o₃), nrog kev ua kom zoo nkauj feem ntau yog li 90% rau 99%, feem ntau muaj cov dab neeg los ntawm lub siab, na₂o, thiab lwm yam). Qhov siab dua cov kev coj dawb huv, qhov zoo dua ntawm kev ua tau zoo.
01
Crystal Qauv
Dawb fused alumina belongs rau - al₂o₃ crystal qauv, nrog ib tug qauv hexagonal kaw lus, tus qauv tuab, thiab muaj zog ruaj khov.
02
Kev tshwm sim
Hauv nws lub xeev ntuj, nws yog cov nplais dawb lossis hmoov. Tom qab raug tsoo, nws nthuav qhia cov duab angular, nrog cov ntxhib partle siurfaces, uas yog qhov zoo los ua ke nrog lwm cov ntaub ntawv.
03
Cov Khoom Siv Lub Cev
Lub mohs hardness yog 9.0 (thib ob tsuas yog pob zeb diamond thiab silicon yog kwv yees li siab dua li ntawm 1800 cov thermal nthuav tawm coefficiention yog me me.

Pob:1 mt lub hnab loj lossis 25kg hnab ntawv ntawm ib qho pallet; Raws li cov neeg yuav tsum tau ua
Dawb Fused Alumina muaj kev ua tau zoo raws li hauv qab no
Siab hardness thiab hnav tsis kam
Lub hardness yog thib ob nkaus xwb rau pob zeb diamond thiab silicon carbide, nrog cov coj zoo heev. Nws yog qhov haum rau cov khoom sib tsoo, polishing thiab lwm yam ua.
01
Kub Ceev
Kev ua siab ntev, tsis soften lossis decompose thaum muaj kev kub ntxhov, thiab muaj qhov zoo {{}} {{{1} {1}-}}}}}} qhov chaw dej khov.
02
Tshuaj Muaj Peev Xwm
Lub zog tiv thaiv kom xeb tawm media xws li cov kua qaub thiab alkalis, tsis muaj kev tawm tsam nrog cov hlau oxesis feem ntau (tshwj tsis yog alkalis thiab hydrofluoric acid).
03
Kev rwb thaiv tsev
Muaj hluav taws xob rwb hluav taws xob kev ua tau zoo, tuaj yeem siv ua cov khoom siv rwb thaiv tsev hauv cov khoom siv hluav taws xob.
04
Tsis - sib nqus
Tsis muaj cov yeeb tshuaj sib nqus, haum rau cov xwm txheej tsis raug rau cov hlau nplaum (xws li cov khoom siv ua kom haum).
05
Daim ntaub ntawv Fused dawb
Cov kev siv dawb corundum npog ntau thaj teb xws li abrasives, Refrasives, Refractory cov ntaub ntawv, ceramics, thiab lwm yam yog cov hauv qab no:
Nyob rau hauv daim teb ntawm abrasives
Nov yog lub chaw thov tseem ceeb ntawm dawb corundum. Los ntawm kev noj kom zoo dua nws cov hardness siab thiab hnav tsis kam, ntau cov cuab yeej uas cov uas muaj cov khoom siv abrasity thiab cov khoom lag luam tuaj yeem ua tau
Muab cov abrasives
Xws li sib tsoo log, sib tsoo pob zeb, sib tsoo, siv rau cov hlau sib tsoo (xws li cov cuab yeej siv roj carry (xws li cov cuab yeej ua kom sib sib zog (xws li cov cuab yeej sib tsoo, cov kabmob polishing).
Coated abrasives
Xws li cov xuab zeb, xuab zeb ntaub, xuab zeb siv xuab zeb, thiab lwm yam.
Pub dawb abrasives
Xws li kev sib tsoo hmoov, sandblasting abrasives, siv rau xeb tshem tawm ntawm hlau chaw, lossis polishing ntawm cov iav thiab piide ntawm cov iav, lossis pade, raws li meej tu ntawm aerospace Cheebtsam.
