Brown fused aluminamuaj ib tug heev hardness, tab sis sib tsoo log ua los ntawm nws yuav ua tau ib tug superhard los yog mos. Vim li cas qhov no? Vim li cas thiaj tuaj yeem sib tsoo lub log ua los ntawm tib cov khoom siv raw, xim av fused alumina, muaj qib sib txawv hardness?
Nws hloov tawm tias hardness ntawm ibxim av aluminium oxide sib tsoo logtsis yog txiav txim los ntawm tus abrasive nws tus kheej, tab sis los ntawm cov binder siv los ua lub log. Muaj ntau cov ntaub ntawv siv los ua cov log sib tsoo, feem ntau suav nrog ceramics, resins, thiab roj hmab. Kev sib tsoo lub log ua nrog peb hom kev sib khi no yog hu ua lub log sib tsoo nyuaj, nruab nrab- cov log sib tsoo mos, thiab cov log sib tsoo mos.
Vim li cas xim av aluminium oxide sib tsoo lub log ua rau peb hom sib txawv? Qhov sib txawv tseem ceeb nyob hauv lawv daim ntawv thov. Kev sib tsoo nyuaj yog cov uas cov khoom abrasive nyuaj rau tshem tawm ntawm lub log. Hauv kev txiav cov hlau mos, qhov tseem ceeb heev uas cov khoom abrasive yog qhov nyuaj rau kev tshem tawm, siv lub log sib tsoo nyuaj. Txawm li cas los xij, hauv kev ua cov hlau tawv tawv, txhawm rau tiv thaiv cov txheej txheej ntawm abrasive los ntawm kev ua npub tom qab sib tsoo, nws yog qhov tsim nyog rau cov khoom abrasive kom tshem tau yooj yim dua, nthuav tawm txheej tshiab thiab ua kom muaj zog txiav. Nyob rau hauv cov ntaub ntawv no, mos sib tsoo log feem ntau yog siv.
Nov yog tsib yam ntxwv tseem ceeb ntawm cov xim av aluminium oxide sib tsoo log. Kev nkag siab txog cov yam ntxwv no yuav pab peb nkag siab tias vim li cas lawv thiaj li nrov.
1. Brown aluminium oxide sib tsoo lub log tuaj yeem ua haujlwm sib tsoo tsis tu ncua rau lub sijhawm ntev yam tsis muaj kev sib tsoo ntau dhau los yog txhaws.
2. Brown aluminium oxide sib tsoo lub log tuaj yeem siv rau kev sib tsoo cov ntaub ntawv ntawm qhov sib txawv hardness, thiab muaj kev cuam tshuam zoo heev ntawm kev sib tsoo cov npoo nkhaus thiab cov hlau tshwj xeeb.
3. Brown aluminium oxide sib tsoo lub log tuaj yeem muab qhov ntim loj dua thiab cov nyhuv sib tsoo zoo ib yam, thiab tuaj yeem txo lub sijhawm sib tsoo zoo thiab tshem tawm qee qhov kev ua haujlwm.
4. Haum rau kev sib tsoo zoo tib yam ntawm workpieces ua los ntawm siab - lub zog thiab siab - cov ntaub ntawv hardness xws li quenched steel, siab - ceev steel, thiab siab - carbon steel. Nws kuj tseem siv tau rau machining threads, gears, thiab nyias -walled qhov chaw.
5. Siv rau kev sib tsoo sab hauv thiab sab nraud, sib tsoo nto, tsis muaj kev sib tsoo, cov cuab yeej sib tsoo, thiab ntau yam tshwj xeeb - lub hom phiaj sib tsoo tshuab thiab semi- precision sib tsoo.
