Cov txiaj ntsig zoo ntawm Boron Nitride Ceramics yog Cov no
Aug 10, 2023
Boron nitride ceramics, tseem hu ua BN ceramics, yog cov khoom tsim nyog rau ntau yam kev siv. Qhov no yog vim hais tias lawv muaj ntau yam zoo nkauj ntawm cov khoom tsim nyog, ua rau lawv xaiv qhov zoo tshaj plaws rau ntau yam kev lag luam thiab kev siv txuj ci.
Ua ntej, ib qho ntawm qhov zoo tshaj plaws ntawm boron nitride ceramics yog lawv cov khoom siv thermal zoo. Lawv muaj qhov tshwj xeeb thermal conductivity, cia lawv tiv taus qhov kub thiab txias yam tsis muaj kev puas tsuaj. Tsis tas li ntawd, lawv nthuav tawm thermal expansion tsawg heev, uas txhais tau hais tias lawv khaws lawv cov duab thiab tsis tawg lossis deform nyob rau hauv qhov kub thiab txias. Qhov no ua rau lawv cov ntaub ntawv zoo tshaj plaws rau kev siv kub-kub, xws li hauv aerospace thiab metallurgical industries.
Thib ob, boron nitride ceramics paub txog lawv cov khoom siv hluav taws xob zoo heev. Tsis tsuas yog lawv muaj peev xwm tiv taus hluav taws xob conductivity, tab sis lawv kuj muaj lub zog dielectric zoo, ua rau lawv cov ntaub ntawv zoo tshaj plaws rau kev siv hluav taws xob thiab hluav taws xob.
Ntxiv nrog rau cov khoom no, boron nitride ceramics kuj tsis muaj tshuaj lom, tshuaj lom neeg, thiab tiv taus corrosion. Qhov no ua rau lawv zoo tagnrho rau kev siv khoom noj, kev kho mob, thiab kev lag luam tshuaj. Lawv kuj yog cov hnav-resistant, nrog superior zog thiab hardness, uas ua rau lawv zoo tagnrho rau tej cuab yeej, pwm, thiab abrasives.
Thaum kawg, cov khoom lubrication zoo ntawm boron nitride ceramics ua rau lawv zoo tagnrho rau kev siv hauv high-speed thiab high-temperature applications. Lawv ua haujlwm raws li cov khoom siv tiv thaiv kev hnav zoo heev thiab sib xws nrog cov hlau, yas, thiab lwm yam khoom siv.
Hauv kev xaus, qhov tshwj xeeb ua ke ntawm thermal, hluav taws xob, hnav-tiv taus, thiab lubrication zog ua rau boron nitride ceramics yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev lag luam, kev tshawb fawb, thiab kev siv kho mob. Lawv muab ntau yam txiaj ntsig kev ua tau zoo thiab tau dhau los ua qhov kev xaiv nrov zuj zus rau cov tuam txhab niaj hnub no.
