Cov txheej txheem kuaj ntawm Boron Nitride Ceramics

Kev sim txheej txheem ntawm boron nitride ceramics

Boron nitride ceramics yog ib chav kawm ntawm cov ntaub ntawv siab heev paub txog lawv cov thermal conductivity, zoo hluav taws xob rwb thaiv tsev, thiab tshwj xeeb txhua yam muaj zog. Vim lawv cov khoom tshwj xeeb, lawv pom cov ntawv thov dav hauv ntau thaj chaw xws li hluav taws xob mus rau aerospace.

Txhawm rau kom ntseeg tau tias lawv qhov kev ua tau zoo, nws yog ib qho tseem ceeb uas yuav tsum tau ua nruj me ntsis kev ntsuam xyuas ntawm boron nitride ceramics ua ntej lawv ua hauj lwm hauv cov ntawv thov. Ntawm no, peb nthuav qhia cov txheej txheem kev sim ua tiav uas tsim los ntsuas cov khoom ntawm cov khoom no kom raug thiab ua tau zoo.

Thawj kauj ruam hauv cov txheej txheem sim yog kev tshuaj xyuas qhov muag. Cov ceramics raug tshuaj xyuas rau tej yam tsis xws li tawg, chips, los yog impurities uas yuav cuam tshuam rau lawv cov kev ua tau zoo. Tom ntej no, qhov ceev ntawm cov khoom yog ntsuas siv Archimedes txoj kev los txiav txim nws porosity thiab seem stability.

Cov theem tom ntej suav nrog ntsuas cov khoom thermal ntawm cov ceramics, uas tuaj yeem ua tiav los ntawm kev ntsuas thermal conductivity. Qhov no suav nrog cua sov ib qho qauv ntawm cov khoom siv thiab ntsuas tus nqi ntawm cov cua sov hloov mus los ntawm nws. Cov thermal expansion coefficient, tshwj xeeb kub muaj peev xwm, thiab thermal diffusivity ntawm boron nitride ceramics kuj ntsuas, nrog rau lawv cov hluav taws xob resistivity thiab dielectric tas li.

Tom qab ntawd, kev kuaj tshuab yog ua los txiav txim siab cov khoom siv lub zog, toughness, thiab hardness. Kev ntsuam xyuas xws li lub zog tensile, compressive zog, thiab lub zog flexural yog ua los ntsuas cov khoom tiv thaiv rau sab nraud quab yuam.

Lwm qhov kev sim uas yuav ua tau suav nrog kev sim tshuaj tiv thaiv kab mob, kev sim hnav tsis kam, thiab kev sim tribology. Tag nrho cov ntaub ntawv tau txais los ntawm cov kev ntsuam xyuas raug txheeb xyuas los txiav txim siab cov ntaub ntawv tsim nyog rau cov ntawv thov tshwj xeeb.

Hauv kev xaus, kev sim cov txheej txheem ntawm boron nitride ceramics yog ib kauj ruam tseem ceeb hauv kev ua kom lawv cov kev ua tau zoo hauv kev siv tswv yim. Los ntawm kev ua raws li kev soj ntsuam nruj, peb tuaj yeem txiav txim siab cov khoom ntawm cov ntaub ntawv no thiab xyuas kom lawv muaj kev nyab xeeb, zoo, thiab kev ntseeg tau.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
