Boron nitride Hmoov yog ib yam khoom siv tau ntau yam uas tau txais kev lees paub dav thoob plaws ntau yam lag luam vim nws cov yam ntxwv tshwj xeeb. Paub txog nws cov thermal conductivity siab, hluav taws xob rwb thaiv tsev, thiab tshuaj lom neeg thiab kub siab, boron nitride hmoov muaj ntau yam kev siv. Txij li cov khoom siv hluav taws xob mus rau metallurgy, cov hmoov tshwj xeeb no tau hloov pauv ntau yam lag luam.
Ib qho ntawm cov kev siv tseem ceeb ntawm boron nitride hmoovyog ua ib lub roj nplua nyeem. Nws cov khoom siv lubricating yog vim nws cov qauv zoo li graphite. Yog li ntawd, nws feem ntau siv ua cov roj nplua nyeem qhuav hauv cov xwm txheej uas tsis pub siv cov roj lossis cov roj nplua nyeem ib txwm muaj, xws li hauv qhov chaw kub siab. Boron nitride hmoov ua haujlwm ua ib txheej tiv thaiv, txo kev sib txhuam thiab hnav ntawm cov nplaim mating. Cov yam ntxwv no ua rau nws zoo tagnrho rau cov ntawv thov uas cuam tshuam nrog kev sib cuag swb thiab kev ua haujlwm ceev ceev.
Hauv kev lag luam hluav taws xob, boron nitride hmoov ua lub luag haujlwm tseem ceeb. Nws cov khoom siv hluav taws xob zoo heev ua ke nrog kev ua kom sov siab ua rau nws zoo tagnrho rau cov dab dej kub, cov khoom siv hluav taws xob insulators thiab cov khoom siv hauv cov khoom siv hluav taws xob. Los ntawm kev ua kom cov cua sov tsim los ntawm cov khoom siv hluav taws xob, boron nitride hmoov pab tswj qhov kub thiab txias zoo tshaj plaws, ua kom ntseeg tau tias lub neej ntev thiab kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.
Hmoov Boron nitride kuj siv dav hauv kev lag luam hlau. Nws ua haujlwm ua tus neeg sawv cev tso tawm muaj txiaj ntsig thaum lub sijhawm casting, tiv thaiv cov hlau molten los ntawm kev lo rau ntawm qhov chaw pwm, yog li ua rau demolding yooj yim. Tsis tas li ntawd, cov hmoov zoo no tuaj yeem siv ua cov khoom siv refractory hauv crucible coatings thiab hauv kev tsim cov crucibles, nozzles thiab lwm yam khoom rau kev siv kub siab. Nws cov tshuaj lom neeg ruaj khov thiab thermal shock tiv taus ua rau nws yog qhov kev xaiv zoo rau hom kev siv no.
Lwm thaj chaw tshiab uas tau txais txiaj ntsig los ntawm kev siv boron nitride hmoovyog kev lag luam tshuaj pleev ib ce. Nws cov yam ntxwv tshwj xeeb, suav nrog lub peev xwm tawg lub teeb thiab cov yam ntxwv nqus roj, ua rau nws yog ib qho khoom xyaw tshwj xeeb hauv ntau yam tshuaj pleev ib ce, xws li hmoov, lub hauv paus thiab tshuaj pleev. Boron nitride hmoov muab cov khoom no cov qauv du uas ua rau lawv yooj yim rau kev thov thiab sib tov. Tsis tas li ntawd, nws lub peev xwm los cuam tshuam lub teeb pab txo qhov pom ntawm wrinkles thiab lwm yam blemishes, ua rau daim tawv nqaij ci ntsa iab, zoo nkauj.
Hauv kev ua liaj ua teb, boron nitride hmoov yog siv ua phytonutrient. Nws yog ib qho chaw ntawm boron, ib qho micronutrient tseem ceeb uas yuav tsum tau rau kev loj hlob ntawm cov nroj tsuag kom zoo. Los ntawm kev ntxiv boron nitride hmoov rau hauv av, koj ua kom muaj cov as-ham tseem ceeb no, txhim kho kev noj qab haus huv ntawm cov nroj tsuag thiab ua kom cov qoob loo ntau ntxiv.
Ntxiv rau cov ntawv thov uas tau hais los no, boron nitride hmoovyog siv rau hauv kev tsim cov khoom siv ceramics, xim thiab coatings, ua tus neeg sawv cev tso tawm hauv kev tsim cov yas, thiab txawm tias hauv cov ntawv thov aerospace qhov twg nws cov khoom sib dua tab sis ruaj khov yog. Qhov pov thawj tsis muaj nqi.
Xaus lus, hmoov boron nitride yog ib yam khoom zoo heev uas muaj ntau yam kev siv hauv ntau yam lag luam. Nws qhov kev ua tau zoo ua ke nrog kev ua tau zoo ua rau nws yog ib feem tseem ceeb ntawm kev siv tshuab niaj hnub thiab kev nce qib. Txij li cov roj nplua nyeem mus rau cov khoom siv hluav taws xob, cov tshuaj pleev ib ce mus rau kev ua liaj ua teb, kev siv hmoov boron nitride txuas ntxiv nthuav dav, qhib txoj hauv kev tshiab rau kev tsim kho tshiab thiab pab txhawb rau kev nce qib ntawm ntau yam lag luam.
Peb yog tus muab khoom Boron nitride saum toj kawg nkaus hauv Suav teb, muab ntau hom Boron nitride, tib lub sijhawm peb tuaj yeem tshawb nrhiav thiab tsim cov Boron Nitride tshiab raws li qhov xav tau tshwj xeeb ntawm peb cov neeg siv khoom. Nov yog peb qee qib Boron nitride, yog xav paub ntxiv thov hu rau ntawm info@theoremchem.com
