Dawb aluminium oxidetau dhau los ua ib qho ntawm cov khoom siv dav siv ntau tshaj plaws hauv kev ua lag luam. Nws cov tshuaj tiv thaiv tseem ceeb yog Al₂O₃, thiab nws tuaj yeem muab faib ua qib sib txawv raws li purity ntawm aluminium oxide hmoov. Vim nws lub siab tawv thiab nws tus kheej zoo-nplaum muaj peev xwm, nws yog dav siv los ntxuav, xeb tshem tawm, kho nto, precision xov, thiab sib tsoo ntawm ntau yam khoom tawv thiab nkig. Yog li, yuav ua li cas cov qoob loo tswj tau thaum lub sij hawm tsim khoom?
Crystal Structure thiab Tus Kheej -Sharpening Performance
Dawb aluminium oxide yog ib hom polycrystalline abrasive zoo ib yam li SG abrasive. Piv nrog rau cov tsoos abrasives, nws tuaj yeem ua tiav nws tus kheej zoo dua -kev ua tau zoo nyob rau hauv qis sib tsoo quab yuam. Thaum lub sij hawm sib tsoo, cov npoo hnav tuaj yeem tawg raws lub ntsej muag siv lead ua, nthuav tawm cov npoo tshiab ntse thiab tswj kev sib tsoo ruaj khov.
Txhawm rau kom ua tiav cov qoob loo zoo ib yam, cov txheej txheem tsim khoom yuav tsum muaj kev tswj hwm nruj ntawm cov khoom siv raw, melting kub, txias ceev, thiab crushing txoj kev. Yog tias qhov kub hnyiab kub dhau heev lawm, siv lead ua kev loj hlob tuaj yeem tshwm sim, cuam tshuam rau tus qauv microcrystalline qub thiab txo qhov kev ua haujlwm ntawm cov abrasive.
Grain Size Control Thaum lub sij hawm ua
Fine-grain dawb aluminium oxide feem ntau yog tsim los ntawm kev tswj qis -kub sintering thiab cov txheej txheem ua tiav. Thaum lub sij hawm tsim khoom, yam xws li qhov kub thiab txias thiab cov khoom ntws yuav tsum tau ua tib zoo tswj kom ntseeg tau tias cov qoob loo zoo ib yam.
Hauv kev tsim cov cuab yeej abrasive, tswj cov qoob loo kom zoo pab txhim kho kev sib tsoo thiab qhov zoo. Piv txwv li, thaum siv rau hauv kev sib tsoo lub log, zoo - cov nplej abrasives tuaj yeem txo cov log khiav thiab txhim kho qhov ua tiav ntawm cov khoom ua haujlwm. Kev sib tsoo quab yuam tuaj yeem nce ntxiv nrog kev hnav khaub ncaws, tso cai tshem tawm cov khoom ruaj khov thaum lub sijhawm ua haujlwm.
Cov txiaj ntsig ntawm cov qoob loo loj rau kev sib tsoo
Tom qab hnav khaub ncaws, cov nplej abrasive ntawm lub log sib tsoo tuaj yeem tshwm sim nyob rau hauv ntau lub xeev, nrog rau cov nplej tiaj tus, cov nplej me ntsis tawg, thiab cov nplej tawg tag. Qhov xwm txheej ntawm cov npoo abrasive ncaj qha cuam tshuam rau kev txiav muaj peev xwm thiab kev sib tsoo.
Thaum zoo -grain dawb aluminium oxide yog siv rau kev sib tsoo cov ntaub ntawv xws li yttrium vanadate crystals, alumina ceramics, thiab granite, sib tsoo qhov tob muaj qhov tseem ceeb ntawm kev sib tsoo quab yuam. Cov ntaub ntawv nyuaj zoo li alumina ceramics feem ntau xav tau kev sib tsoo ntau dua, thaum cov ntaub ntawv siv lead ua softer xav tau tsawg zog.
Xaiv qhov loj npaum li cas yog qhov tseem ceeb rau kev ua tiav qhov sib npaug ntawm kev sib tsoo efficiency thiab nto tiav. Kev tswj kom zoo ntawm cov dawb aluminium oxide grain loj thaum lub sij hawm tsim khoom kom ruaj khov kev ua tau zoo thiab ua rau nws haum rau ntau yam kev sib tsoo daim ntawv thov.
