Hauv kev lag luam kev lag luam ntawm tshuaj lom neeg, lub zog, thiab kev tiv thaiv ib puag ncig, cov kav dej yog zoo li "cov hlab ntsha" ntawm cov khoom siv, tas li thauj ntau yam xov xwm tseem ceeb. Tab sis qee qhov kev ua haujlwm tuaj yeem hu ua "purgatory": qhov kub thiab txias ib puag ncig tuaj yeem ua rau cov hlau mos, muaj zog acids thiab alkalis tuaj yeem ua rau cov yeeb nkab phab ntsa, thiab cov kua dej uas muaj cov khoom yuav txuas ntxiv mus thiab hnav. Lub sijhawm no, cov kav dej ib txwm muaj feem ntau tawm tsam, thaumsilicon carbide pipelinesdaws cov teeb meem no nrog lawv cov xwm txheej unbreakable.
Yug Muaj Zog: Kev Ua Haujlwm Password ntawm Silicon Carbide
Lub zog ntawm silicon carbide ceramics nyob hauv nws "cov khoom siv noob" - silicon carbide ceramics hu ua "dub pob zeb diamond" ntawm kev lag luam, nrog peb qhov zoo.
Nws hardness yog dhau qhov kev xav, thib ob tsuas yog pob zeb diamond thiab txog li tsib npaug ntawm cov hlau zoo tib yam. Tau ntsib nrog cov kua dej yaig uas muaj cov khoom siv, nws zoo li hnav "cov ris tsho hnav-tiv taus" uas tsis yooj yim hnav nyias thiab muaj lub neej ua haujlwm ntev dua li cov kav hlau. Nyob rau hauv qhov kub thiab txias ib puag ncig, nws yog ib tug 'ceev tus tswv', txawm nyob rau hauv qhov kub ntawm ntau txhiab degrees Celsius, nws cov qauv tseem nyob ruaj khov, tsis zoo li stainless hlau uas muaj ib tug cia li poob rau hauv lub zog ntawm me ntsis kub. Thiab nws tuaj yeem tiv taus qhov kub thiab txias hloov pauv, thiab nws yuav tsis tawg txawm tias dheev raug rau cov xov xwm kub kub hauv lub caij ntuj no.
Qhov tseem ceeb tshaj plaws yog nws "txoj kev tiv thaiv corrosion", uas tuaj yeem hu ua acid-base "immune". Txawm hais tias nws yog cov muaj zog acids xws li concentrated sulfuric acid thiab hydrofluoric acid, siab concentration ntawm sodium hydroxide thiab muaj zog hauv paus, los yog txawm ntsev tsuag thiab molten hlau, nws yog ib qho nyuaj rau corrode nws cov yeeb nkab phab ntsa. Qhov no daws qhov teeb meem loj ntawm pipeline corrosion thiab to hauv ntau qhov kev lag luam scenarios.
Piv rau kev lig kev cai: vim li cas nws thiaj li ntseeg tau ntau dua?
Piv nrog rau cov kav dej ib txwm muaj, qhov zoo ntawm cov kav dej silicon carbide tuaj yeem hais tau tias yog "kev tawm tsam txo qis".
Cov kav hlau hlau yog qhov ua rau softening ntawm qhov kub thiab txias thiab tuaj yeem cuam tshuam electrochemical corrosion thaum raug cov kua qaub thiab alkali. Cov impurities tej zaum yuav precipitate thaum lub sij hawm thauj mus los ntawm precision media, cuam tshuam rau lawv zoo. Txawm hais tias engineering yas kav yog corrosion-resistant, lawv qhov ntsuas kub tsis kam yog tsawg heev, feem ntau tsawg dua 200 ℃, thiab lawv kuj ua rau cov laus thiab tawg tawg. Cov kav dej ceramic feem ntau tiv taus qhov kub thiab hnav, tab sis lawv nkig dhau lawm thiab tuaj yeem tawg nrog kev hloov pauv me ntsis.
Thiab cov kav dej silicon carbide zoo kawg nkaus zam cov kev tsis txaus no, nrog peb lub peev xwm loj ntawm hardness, kub tsis kam, thiab corrosion kuj tau siv tag nrho, uas ua tau raws li cov kev cai tseem ceeb ntawm kev lag luam niaj hnub rau "ntev ntev, ruaj khov, thiab kev saib xyuas tsawg" ntawm cov kav dej.
Nkag mus rau kev lag luam: Nws lub xub ntiag tuaj yeem pom nyob txhua qhov chaw
Niaj hnub no, cov kav dej silicon carbide tau dhau los ua "tus qauv" rau ntau yam kev ua haujlwm hnyav. Hauv kev lag luam tshuaj, nws yog lub luag haujlwm rau kev thauj ntau cov kua qaub thiab alkalis tsis tas yuav hloov thiab kho; Nyob rau hauv desulfurization thiab denitrification system ntawm cov nroj tsuag fais fab, nws tuaj yeem tiv taus qhov kub thiab txias siab corrosive ib puag ncig, thiab nws cov kev pab cuam lub neej tuaj yeem tshaj 10 xyoo.
Nyob rau hauv semiconductor factories, nws ultra-siab purity ua kom tsis muaj kuab paug nyob rau hauv kev thauj mus los ntawm high-purity gases, ua rau nws "tus qauv kub" rau chip manufacturing; Hauv kev lag luam metallurgical, nws tuaj yeem thauj cov khoom kub kub thiab cov hmoov ore tsis ntshai kev yaig thiab hnav. Txawm tias nyob rau hauv kev lag luam aerospace, qhov kub-kub gas ducts ntawm foob pob ua ntxaij cav tsis tuaj yeem ua yam tsis muaj kev txhawb nqa.
Nrog rau kev ua tiav ntawm kev siv thev naus laus zis hauv tsev, tus nqi ntawm silicon carbide pipelines tau txo qis, thiab lawv kuj tuaj yeem hloov kho rau cov chaw tawm tshiab xws li hydrogen zog thiab aerospace los ntawm cov txheej txheem tshuaj kho mob. Qhov no ' Pob Zeb Diamond Warrior ' nyob rau hauv cov kav xa dej yog siv nws lub zog los tiv thaiv kev ua haujlwm ruaj khov ntawm ntau yam kev lag luam.
