Nyob rau hauv kev sib ntaus sib tua ntawm kev tsim khoom, cov kav dej yog zoo li "lifeline" uas tswj cov kev lag luam ntawm kev lag luam, tab sis lawv ib txwm ntsib kev hem thawj ntawm kev hnav thiab corrosion. Thaum cov kav hlau siv ib txwm siv "rov qab" nyob rau hauv kev ua haujlwm hnyav, tus neeg saib xyuas hom tshiab -Cov tshuaj tiv thaiv sintered silicon carbide ceramic lineryog ntsiag to hloov cov cai ntawm qhov kev ua si.
Ceramic armor uas yog tawv dua li hlau
Los ntawm cov txheej txheem sintering tshwj xeeb, silicon carbide hmoov ua tiav qib molecular reconstruction ntawm qhov kub thiab txias ntawm 2150 ℃, tsim cov qauv hnav-resistant ntau dua li cov hlau zoo tib yam. Qhov micro theem 'molecular vuam' thev naus laus zis muab cov txheej txheem ceramic hauv qhov tawv tawv piv rau pob zeb diamond, tab sis nrog cov khoom tiv thaiv corrosion uas hlau tsis tuaj yeem sib xws. Thaum muaj ntau cov xov xwm corrosive ntws los ntawm cov raj xa dej, cov txheej txheem tiv thaiv ceramic zoo li muab "golden tswb cover" rau ntawm lub raj xa dej, maj mam tiv nrog qhov chaw muaj corrosive heev.
Lub teeb yuag thiab kev tiv thaiv ntev
Kev hnav-tiv taus cov kev daws teeb meem feem ntau xav tau kev sib haum xeeb ntawm qhov hnyav thiab lub neej ntev, thaum qhov ntom ntawm silicon carbide ceramic hauv ob sab phlu tsuas yog ib feem peb ntawm cov hlau. Lub tswv yim tsim qauv ntawm "siv softness los kov yeej hardness" tso cai rau lub raj xa dej kom tswj tau cov dej ntws zoo thaum txo qhov hnyav tag nrho.
Economic account ntawm tag nrho cov lifecycle
Ntawm qhov chaw tsheb thauj mus los tsuas, kev pabcuam lub neej ntawm cov kav dej khoov nrog cov kab hluav taws xob tuaj yeem ncav cuag ob peb zaug ntawm cov kav hlau zoo tib yam; Nyob rau hauv thermal fais fab nroj tsuag, kev tu lub voj voog ntawm desulfurization pipelines yog txuas ntxiv, zoo heev txo qhov poob los ntawm kev kaw thiab tu. Tus yam ntxwv ntawm "ib lub sijhawm peev, txiaj ntsig mus ntev" yog hloov kho tus nqi ntawm cov kav dej. Qhov tseem ceeb tshaj, nws tus du thiab daim iav zoo li ceramic nto tuaj yeem txo qee qhov kev khiav hauj lwm, tsis tu ncua tsim cov txiaj ntsig txuag hluav taws xob thaum lub sijhawm ua haujlwm ntev.
Los ntawm " mais kawg" ntawm kev thauj mus los ntawm slurry hauv mines mus rau kev kho cov xov xwm corrosive hauv cov chaw ua si tshuaj, qhov kev sib xyaw ua ke zoo tshaj plaws ntawm ceramics thiab hlau yog sau tus qauv tshiab hauv kev lag luam hnav thiab corrosion kuj. Nws ua pov thawj nrog lub zog ntawm thev naus laus zis tias kev tiv thaiv tiag tiag tsis yog dag hauv cov ntaub ntawv tuab, tab sis nyob rau hauv kev tswj xyuas meej ntawm lub cev txwv. Thaum peb rov hais dua cov kav dej nrog cov ceramics, peb tseem ceeb tshaj qhov tseem ceeb tshaj plaws nyob rau hauv cov khoom siv.
