Nyob rau hauv cov ces kaum ntawm Hoobkas kev cob qhia thiab kev thauj mus los tsuas, muaj ib qho tseem ceeb tab sis yooj yim overlooked "lub luag hauj lwm" - lub conveying pipeline. Lawv thauj cov ntxhia, tshuaj khib, thiab cov khoom siv tshuaj lom neeg ib hnub dhau ib hnub, thiab lawv cov phab ntsa sab hauv tau raug kev sib txhuam thiab cuam tshuam los ntawm cov ntaub ntawv. Sij hawm dhau mus, lawv nquag hnav thiab tsim kua muag, cov dej xau, uas tsis tsuas yog cuam tshuam rau kev tsim khoom tab sis kuj yuav tsum tau saib xyuas kim thiab hloov pauv. Lub silicon carbide hnav-resistant pipeline hauv ob sab phlu peb yuav tham txog niaj hnub no zoo li muab ib txheej ntawm "invisible steel armor" rau ntawm cov kav dej zoo tib yam, ntsiag to daws qhov teeb meem loj no.
Tej zaum ib tug yuav nug, yog dab tsisilicon carbide? Qhov tseeb, nws tsis yog mysterious. Qhov tseem ceeb, nws yog ib qho khoom siv hluavtaws tsim los ntawm cov pa roj carbon thiab silicon, nrog lub hardness thib ob tsuas yog pob zeb diamond.
Piv rau cov phab ntsa sab hauv ntawm cov kav dej zoo tib yam, qhov nyuaj ntawm silicon carbide hauv ob sab phlu yog ntau dua. Thaum cov khoom ntse ore thiab high-speed ntws mortar ntxuav tawm ntawm phab ntsa sab hauv, silicon carbide tuaj yeem ua tau zoo li cov ntaub thaiv npog los thaiv kev sib txhuam thiab tiv thaiv khawb los yog dents los ntawm yooj yim tshwm sim. Txawm hais tias kev thauj mus los ntev ntawm cov ntaub ntawv hnav siab, nws cov phab ntsa sab hauv tuaj yeem nyob tiaj tus thiab du, tsis ua kom tuab lossis nkig vim hnav, ua rau lub neej ntev ntawm cov raj xa dej.
Ntxiv nrog rau kev hnav tsis kam, nws kuj muaj cov txuj ci zais - 'tuaj yeem tiv thaiv kev tsim kho'. Hauv kev tsim khoom, cov ntaub ntawv xa tawm feem ntau tsis yog "hauv av", tab sis kuj tseem tuaj yeem nqa qhov kub thiab txias acid-puag corrosion. Piv txwv li, hauv kev lag luam chemical engineering, qee cov ntaub ntawv muaj zog corrosiveness, thiab hauv ob sab phlu ntawm cov kav dej zoo tib yam tau yooj yim corroded thiab tev tawm; Hauv kev lag luam metallurgical, cov ntaub ntawv kub kub tuaj yeem ua rau deformation thiab tsis ua haujlwm ntawm lub hauv ob sab phlu. Lub silicon carbide hauv ob sab phlu tuaj yeem tiv taus qhov kub thiab txias ntawm ntau pua degrees Celsius thiab tiv thaiv kev yaig ntawm feem ntau acidic thiab alkaline xov xwm, tswj kev ua haujlwm ruaj khov hauv txhua qhov "qhov hnyav".
Rau cov lag luam, cov txiaj ntsig tau los ntawm cov kab me me no yog qhov pom tseeb heev: tsis tas yuav tsum nquag kaw thiab hloov cov kav dej, txo qhov kev poob los ntawm kev cuam tshuam ntau lawm; Tsis tas yuav rov ua lag luam rau cov nqi tu, nws tuaj yeem txuag tau nyiaj ntau hauv lub sijhawm ntev; Qhov tseem ceeb tshaj, nws tuaj yeem ua kom muaj kev thauj mus los yooj yim thiab zam kev nyab xeeb thiab teeb meem ib puag ncig los ntawm cov kav dej xau.
Los ntawm cov kav dej tsis pom zoo rau "cov cuab yeej hnav-tiv taus" uas tiv thaiv kev tsim khoom lag luam, tus nqi ntawm silicon carbide hnav-resistant pipeline hauv ob sab phlu yog nyob rau hauv nws lub peev xwm " daws teeb meem loj hauv cov ntsiab lus me". Rau cov lag luam uas nrhiav kev ua haujlwm tau zoo thiab ruaj khov, xaiv nws tsis yog tsuas yog kev txhim kho ntawm cov cuab yeej siv, tab sis kuj tseem xav txog lub sijhawm ntev rau kev tsim khoom thiab kev tswj hwm tus nqi.
