Nyob rau hauv niaj hnub industrial teb,ntsuab silicon carbidethiabdawb aluminium oxideyog cov ntaub ntawv tseem ceeb rau kev tsim kev sib tsoo log. Niaj hnub no peb yuav sib piv ob lub abrasives.
Ntsuab silicon carbide yog ib yam khoom uas ua los ntawm high-purity quartz xuab zeb, roj av coke thiab high-zoo silica raws li lub ntsiab raw cov ntaub ntawv, thiab smelted nyob rau hauv lub kub kub nyob rau hauv lub cub tawg kuj. Nws lub siab tawv thiab zoo hnav tsis kam ua rau nws ci ntsa iab hauv kev sib tsoo cemented carbide, iav kho qhov muag, thiab lwm yam. Cov ntsuab silicon carbide sib tsoo lub log tsis yog tsuas yog muaj cov cuab yeej zoo ntawm tus kheej thiab tuaj yeem tswj kev ruaj ntseg ntawm kev sib tsoo, tab sis kuj muaj qhov zoo. thermal conductivity, uas zoo txo cov cua sov sib xyaw thaum lub sij hawm sib tsoo txheej txheem thiab txhim kho kev ua haujlwm zoo ntawm workpiece nto.
Dawb aluminium oxide yog ib qho khoom siv corundum ua los ntawm alumina hmoov ua raw khoom, uas yog crushed tom qab kub-kub melting thiab txias. Nws hardness yog me ntsis qis dua ntsuab silicon carbide, tab sis nws toughness yog zoo dua, thiab nws yog haum rau sib tsoo cov ntaub ntawv nyuaj xws li stainless hlau thiab high-ceev hlau. Cov dawb aluminium oxide sib tsoo lub log tuaj yeem tswj nws qhov kev ua tau zoo rau lub sijhawm ntev thaum lub sijhawm sib tsoo, txo qhov zaus ntawm kev sib tsoo log hloov thiab txo cov nqi tsim khoom. Nyob rau tib lub sijhawm, dawb corundum sib tsoo log kuj muaj qhov cuam tshuam zoo, uas ua rau nws muaj kev ruaj ntseg ua haujlwm hauv ib puag ncig kev sib tsoo thiab hloov tau.
Thaum muab piv ntsuab silicon carbide thiab dawb txhuas oxide, nws tsis yog nyuaj rau nrhiav tau tias lawv muaj lawv tus kheej zoo. Ntsuab silicon carbide ua tau zoo nyob rau hauv kev sib tsoo cov ntaub ntawv nyuaj nrog nws cov hardness siab thiab zoo heev tus kheej-sharpening, thaum dawb txhuas oxide muaj ib tug zoo dua nyob rau hauv sib tsoo cov ntaub ntawv tawv nrog nws zoo toughness thiab tej yam kuj. Hauv kev siv cov tswv yim, kev xaiv ntawm cov khoom siv sib tsoo log tseem yuav tsum tau hnyav raws li kev ua haujlwm tshwj xeeb.
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev loj hlob ntawm kev lag luam, kev tshawb fawb thiab kev tsim kho thiab kev siv cov khoom siv sib tsoo log yog niaj hnub innovating. Raws li cov neeg sawv cev ntawm kev sib tsoo cov ntaub ntawv, ntsuab silicon carbide thiab dawb txhuas oxide tseem nthuav lawv cov kev ua tau zoo thiab daim ntawv thov teb. Nyob rau hauv lub neej yav tom ntej, peb muaj laj thawj ntseeg tias nrog kev tshawb fawb tob ntawm cov ntaub ntawv tshawb fawb thiab kev tsim kho tshiab ntawm kev lag luam, kev sib tsoo cov ntaub ntawv yuav dhau los ua ntau haiv neeg thiab muaj txiaj ntsig, muab kev txhawb zog rau kev txhim kho kev lag luam niaj hnub.
