Silicon nitride bearing npas yog cov kabmob pob ua los ntawm silicon nitride. Cov khoom muaj qhov zoo ntawm thermal stability zoo, kev txhim kho corrosion, hnav tsis kam, tus kheej lubricating, thiab lwm yam, thiab nws cov kev pabcuam lub neej yog siab dua li ntawm cov khoom muaj nqis zoo tib yam. Nws yog tsim hauv qib high-kawg Daim ntawv thov kev thov nyob rau hauv cov teb ntawm kev lag luam, cua zog tsim hluav taws xob, aerospace, thiab lwm yam.
Vim txoj kev loj hlob sai ntawm lub ntiaj teb kev tsim kho hluav taws xob tshiab nyob rau xyoo tas los no, qhov kev loj hlob tsis tu ncua ntawm cov khoom siv thauj khoom cua tau ua rau lub ntiaj teb xav tau silicon nitride cov kabmob npas txuas ntxiv mus ntxiv, thiab kev ua lag luam loj tau nce raws li, tau txog 480 lab nyiaj Asmeskas nyob rau hauv 2019, thiab ntxiv nplai los ntawm 500 lab las Asmeskasthaum xyoo 2020.
Raws li" Tshawb Fawb Kev Tshaj Tawm Ntawm Kev Thov Kev Ua Lag Luam Kev Xav Tau thiab Kev Txhim Kho Kev Lag Luam ntawm Tuam Tshoj' s Silicon Nitride Bearing Pob Kev Lag Luam los ntawm 2021-2026" tawm los ntawm Kev Tshawb Fawb Txog Kev Lag Luam Tshiab Sijhawm, ntau dua paub zoo silicon nitride cov kabmob npas cov khoom lag luam hauv lub ntiaj teb suav nrog Nyiv' s NSK thiab Tebchaws Asmeskas, companiesnyiamCoorsTek thiab Toshiba Ceramics muaj cov khoom lag luam nyob hauv khw muag khoom thoob ntiaj teb thiab Suav vim lawv cov npe nrov siab, cov khoom lag luam nplua nuj thiab cov khoom zoo dua.
Nrog rau txoj kev loj hlob sai ntawmTuam Tshoj’s kev lag luam, domestic silicon nitride bearing npas manufacturers kuj tseem loj hlob. Cov tuam txhab sawv cev suav nrog Sinoma High-tech, Shanghai Fanlian, thiab Shanghai Khoom Siv Tshawb Xyuas Lub Koom Haum, tab sis lawv tau txwv los ntawm kev tsim thev naus laus zis. Muaj qee qhov sib txawv nruab nrab ntawm qhov ua tau zoo ntawm silicon nitride bearing npas hauv kuv lub teb chaws thiab txawv teb chaws. Tam sim no, 80% ntawm high-end silicon nitride bearing npas yuav tsum tau ua txawv teb. Nyob rau hauv lub neej yav tom ntej, muaj ntau chav rau hloov chaw hauv khw muag khoom high-end rau silicon nitride bearing npas.
Silicon nitride hmoov yog cov khoom siv raw khoom rau kev tsim cov roj silicon nitride cov npas. Cov txheej txheem tam sim no ntawm silicon nitride hmoov suav nrog silicon hmoov nitriding txoj kev thiab cov qauv tshuaj lom neeg. Ntawm nimno, kev siv lub ntsiab ntawm silicon hmoov nitriding txujci thiab tshuaj lom neeg,crho tawm nrog cov hmoov uas npaj los ntawm tus qauv, cov hmoov uas npaj los ntawm tom kawg tau muaj qhov siab dua, kev ua kom zoo dua qub, muaj kev ua haujlwm siab dua, thiab qis dua ntawm cov khoom siv silicon, ua rau nws xaiv thawj rau kev npaj siab silicon nitride bearing npas.
Hauv ntiaj teb, lub tuam txhab Japanese UBE yog lub tuam txhab uas tuaj yeem siv cov tshuaj lom neeg los ua cov tshuaj silicon nitride hmoov rau ntawm qhov loj, tab sis cov tuam txhab txwv tsis pub nws cov khoom xa mus rauTuam Tshojthiab tsuas yog txwv los ntawm kev xa cov khoom raw.
Qhov tseeb ntawm silicon nitride cov npas kabmob tuaj yeem raug faib ua G10～G2 qib raws li cov qauv hauv tebchaws. Nrog kev txhawb nqa ntawm txoj cai hauv tebchaws, cov chaw lag luam hauv zos tau ua cov kev lag luam hauv kev tsim tshuab ntawm silicon nitride bearing npas. Tam sim no, kev ua haujlwm hauv silicon nitride cov npas muaj feem ntau yog ua tiav hauv G5 qib.Qee qhov kev lag luam tuaj yeem ncav G3. Hauv lub ntiaj teb, silicon nitride bearing npas tuam ntxhab,xws li Nyiv’s Tsubaki Nakajima, AKS, Sweden’s SKF, thiab lwm yam, tuaj yeem tsim cov khoom lag luam nrog kev ntsuas siab ntawm G3 thiab G2. Cov khoom lag luam tsim los ntawm lawv muaj lub suab qis, lub neej ntev, thiab kev kub ceev, uas yog favored los ntawm kev ua lag luam.
Cov kws tshuaj ntsuam xyuas kev lag luam tau hais tias raws li ib qho tseem ceeb ntawm cov cuab yeej siv high-end, silicon nitride cov npas kabmob tau siv rau hauv cov cuab yeej siv cua, aerospace thiab lwm cov teb. Nrog rau txoj kev loj hlob ntawm lub davhlau ya nyob twg hauv kev lag luam, qhov kev thov ua lag luam rau silicon nitride cov npas txuas ntxiv tau nce. Hais txog kev tsim tawm, vim yog thev naus laus zis thiab cov khoom siv tsis zoo, qhov tseeb ntawm silicon nitride bearing npas hauvTuam Tshojyog feeb meej hauv G5, thaum cov tuam txhab txawv teb chaws tau ua kom loj-tsim silicon nitride cov kabmob npas cov khoom nrog precision ntawm G3 thiab G2.Tuslub teb chaws’s high-end nitride kev ua lag luam xav tau rau silicon bearing npas vam khom rau kev ntshuam, thiab muaj ntau chav rau kev uakhoomyav tom ntej.
