Kev ceev faj rau kev siv Boron Nitride Ceramics
Jul 31, 2023
Boron nitride ceramics yog cov khoom siv tseem ceeb nrog kev siv dav hauv ntau qhov chaw, suav nrog cov chaw kub kub, hluav taws xob, thiab cov cuab yeej txiav. Raws li cov khoom siv qib siab thiab tsim tshiab, nws yog ib qho tseem ceeb uas yuav tsum siv boron nitride ceramics nrog kev saib xyuas thiab saib xyuas kom tsim nyog. Nov yog qee cov lus qhia los xav txog thaum siv boron nitride ceramics:
1. Siv cov cuab yeej tsim nyog: Boron nitride ceramics yog cov khoom tawg yooj yim thiab tuaj yeem raug puas tsuaj los ntawm cov neeg kho tshuab siab. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov cuab yeej tsim nyog uas tuaj yeem tswj cov khoom siv nrog kev saib xyuas, xws li cov cuab yeej pob zeb diamond thiab cov cuab yeej siv dej txias.
2. Tsis txhob raug cov dej noo thiab av noo: Boron nitride ceramics yog hygroscopic thiab tuaj yeem nqus dej noo los ntawm ib puag ncig. Yog tias cov ceramics raug cov av noo los yog noo noo, nws tuaj yeem ua rau tawg lossis tsis muaj zog ntawm cov khoom. Yog li ntawd, nws yog ib qho tseem ceeb kom khaws cov khoom nyob rau hauv ib qho chaw qhuav thiab ruaj khov.
3. Siv cov iav tiv thaiv: Thaum tuav cov boron nitride ceramics, nws yog ib qho tseem ceeb uas yuav tsum hnav cov iav tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg kom tsis txhob muaj kev sib cuag lossis nqus cov hmoov av.
4. Tswj qhov kub thiab txias: Boron nitride ceramics muaj cov thermal expansion coefficient tsawg, thiab yog li ntawd nws yog ib qho tseem ceeb los tswj qhov kub thiab txias thaum siv. Kev hloov pauv ntawm qhov kub thiab txias tam sim ntawd tuaj yeem ua rau tawg ntawm cov khoom, thiab nws yog ib qho tseem ceeb kom tsis txhob cuam tshuam cov khoom kom sov, tshwj xeeb tshaj yog thaum txias txias.
5. Tsis txhob sib cuag nrog cov kua qaub: Boron nitride ceramics feem ntau tiv taus cov tshuaj feem ntau, tab sis lawv tuaj yeem raug puas los ntawm cov kua qaub uas muaj zog. Nws yog ib qho tseem ceeb kom tsis txhob nthuav tawm cov khoom mus rau ib qho muaj zog acids lossis alkalis.
Los ntawm kev ua raws li cov lus qhia saum toj no, koj tuaj yeem ua kom muaj kev nyab xeeb thiab siv tau zoo ntawm boron nitride ceramics thiab zam kev puas tsuaj rau cov khoom siv. Nrog kev saib xyuas thiab kev saib xyuas kom zoo, boron nitride ceramics tuaj yeem muab kev ua haujlwm ntev thiab ua haujlwm zoo hauv ntau daim ntawv thov.
