Kev piav qhia
Tabular alumina yog ib daim ntawv siab-purity ntawm txhuas oxide uas muaj cov qauv siv lead ua zoo thiab cov khoom tshwj xeeb uas ua rau nws yog ib qho khoom siv zoo heev rau kev siv polishing thiab lapping daim ntaub ntawv. Fine-grained tabular alumina, uas muaj qhov me me me dua li cov qauv tabular alumina, tshwj xeeb tshaj yog siv rau cov hom kev siv no.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov nplua-grained tabular alumina rau polishing thiab lapping yog nws cov hardness siab. Tabular alumina muaj Mohs hardness ntawm 9, uas ua rau nws yog ib qho nyuaj tshaj plaws hauv ntiaj teb. Qhov hardness no tso cai rau nws yooj yim tshem tawm qhov tsis zoo ntawm qhov chaw, xws li khawb lossis nicks, los ntawm ntau yam ntaub ntawv, suav nrog hlau, ceramics, thiab iav.
Tsis tas li ntawd, nplua-grained tabular alumina muaj qhov sib txawv me me, uas txhais tau hais tias cov khoom zoo sib xws hauv qhov loj thiab cov duab. Qhov no ua rau nws yooj yim dua kom ua tiav qhov du, txawm tias tiav thaum siv tabular alumina rau polishing thiab lapping.
Lwm qhov kom zoo dua ntawm kev siv cov nplua-grained tabular alumina yog nws tsis kam rau thermal shock. Qhov no txhais tau hais tias nws tuaj yeem tiv taus qhov kub hloov pauv sai yam tsis muaj kev tawg lossis tawg, uas tuaj yeem yog qhov tseem ceeb hauv kev kub kub polishing thiab lapping txheej txheem.

Tabular Alumina |
Tabular alumina muaj cov cua kub tsis kam, txhua yam muaj zog, tsis kam ua haujlwm, siab tshuaj purity, zoo rwb thaiv tsev zog, acid thiab alkali corrosion kuj.
Tabular alumina yog ib qho kev sib sau ua ke ntawm amorphous thiab zoo li cov khoom siv refractory siab, dav siv hauv steel, casting, petrochemical, ceramics thiab incineration industries nrog rau hluav taws xob rwb thaiv tsev, kiln rooj tog thiab catalyst carriers. Finely hauv av tabular alumina hmoov yog ib yam khoom zoo heev uas siv los ua ib qho muab tub lim hauv epoxy resins lossis resin systems. Nws yog siv los ua kom tau qhov xav tau siab dielectric zog, thermal conductivity thiab hnav tsis kam.
