4. Tshuaj Inertness

Khoom HBN yog cov tshuaj tsis muaj zog, txhais tau tias nws tiv taus cov tshuaj feem ntau. Cov yam ntxwv no ua rau nws haum rau siv nyob rau hauv ib puag ncig hnyav uas raug rau cov tshuaj corrosive yog ib qho kev txhawj xeeb.

5. Lubrication Properties

HBN hauv daim ntawv muaj peev xwm ua tau raws li cov khoom siv roj nplua nyeem. Nws txo kev sib txhuam thiab hnav ntawm qhov zawv zawg qhov chaw, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev lag luam xws li tsheb thiab aerospace.

Kev siv cov khoom HBN khoom

1. Aerospace Cheebtsam

Vim nws cov thermal stability thiab zoo heev thermal conductivity, khoom HBN yog siv nyob rau hauv aerospace daim ntaub ntawv. Nws yog ua hauj lwm nyob rau hauv cov khoom xws li foob pob ua ntxaij nozzles, tshav kub shields, thiab lwm yam high-temperature ib puag ncig.

2. Metallurgy thiab Foundry Operations

Khoom HBN yog siv los ua tus neeg sawv cev tso tawm hauv cov txheej txheem hlau casting thiab molding. Nws ua raws li cov txheej txheem uas tsis yog-stick, ua kom yooj yim tshem tawm cov khoom pov tseg los ntawm pwm.

3. High-temperature Insulators

Khoom HBN ceramics yog siv los ua cov insulators nyob rau hauv ib puag ncig kub. Lawv tuaj yeem tiv taus cua sov thiab muab hluav taws xob rwb thaiv tsev, ua rau lawv muaj txiaj ntsig zoo hauv kev lag luam xws li kev ua semiconductor.

Cov ntaub ntawv ntawm Khoom HBN Khoom

1. Tej Khoom HBN

Qhov no yog hom HBN ntau tshaj plaws. Nws yog tsim los ntawm cov txheej txheem xws li kub nias lossis sintering, uas ua rau cov blocks ntom ntom lossis cov nplooj ntawv ntawm HBN. Cov ntaub ntawv loj no ces machined rau hauv cov duab tshwj xeeb rau ntau yam kev siv.

2. HBN Crucibles thiab Ntim

Khoom HBN yog siv los tsim crucibles thiab ntim rau cov ntawv thov kub. Cov crucibles no yog siv nyob rau hauv cov txheej txheem xws li hlau melting thiab casting, qhov uas lawv muaj zoo heev tiv thaiv thermal shock thiab tshuaj corrosion.

3. HBN Insulators thiab Substrates

Khoom HBN ceramics yog siv los ua insulators thiab substrates hauv kev siv hluav taws xob thiab semiconductor. Lawv muab hluav taws xob rwb thaiv tsev thiab thermal stability, ua rau lawv cov khoom tseem ceeb nyob rau hauv high-power thiab high-frequency li.
