Hauv cov txheej txheem tseem ceeb ntawm kev tsim khoom, cov khoom siv thauj khoom ib txwm ntsib teeb meem xws li hnav thiab corrosion. Ordinary pipelines feem ntau muaj lub neej luv luv thiab cov nqi kho mob siab, uas cuam tshuam rau kev tsim khoom. Qhov tshwm sim ntawmsilicon carbide coj-resistant kav, nrog rau lawv cov kev ua tau zoo heev, tau dhau los ua " riam phom" los daws qhov mob no thiab muab kev tiv thaiv rau kev thauj mus los hauv kev lag luam.
Silicon carbide, raws li ib qho kev sib txuas ua ke inorganic non-metallic khoom, inherently muaj ib tug "tawv" yam ntxwv. Nws hardness yog thib ob tsuas yog pob zeb diamond, thiab nws hnav tsis kam tshaj cov kav dej ib txwm muaj xws li cov kav hlau zoo tib yam thiab cov kav dej ceramic. Txawm tias thaum thauj cov khoom hnav siab uas muaj cov khoom loj thiab cov hmoov, nws tuaj yeem tiv taus yaig thiab ua haujlwm tau zoo rau kev pab cuam lub neej ntawm cov kav dej. Nyob rau tib lub sijhawm, silicon carbide kuj muaj qhov kub thiab txias tsis kam thiab corrosion kuj. Nws tsis tuaj yeem yooj yim puas los ntawm cov xov xwm hnyav xws li kub-kub flue roj, muaj zog acid thiab alkali, uas tso cai rau nws ua lub luag haujlwm ruaj khov hauv ntau yam lag luam xws li metallurgy, tshuaj lom neeg kev lag luam, hluav taws xob, mining, thiab lwm yam.
Piv nrog rau cov kav dej ib txwm muaj, cov kav dej silicon carbide hnav-tiv taus tsis yog "ntev", tab sis kuj coj cov txiaj ntsig zoo rau cov lag luam. Vim nws lub neej ntev ntev, kev lag luam tsis tas yuav hloov cov kav dej ntau zaus, uas tsis yog tsuas yog txo qis rau kev txij nkawm tab sis kuj txo nqi zog thiab khoom siv. Tsis tas li ntawd, cov phab ntsa sab hauv ntawm silicon carbide pipelines yog du, nrog cov dej tsis tshua muaj zog, uas tuaj yeem txo lub zog poob thaum lub sij hawm thauj mus los thiab pab cov lag luam ua tiav kev txuag hluav taws xob thiab txo cov hom phiaj.
Niaj hnub no, raws li kev tiv thaiv ib puag ncig ntsuab dhau los ua cov qauv tseem ceeb ntawm kev tsim kho kev lag luam, qhov zoo ntawm cov kav dej silicon carbide hnav-tiv taus yog qhov tseem ceeb dua. Nws muaj ntau yam khoom siv raw, muaj kuab paug tsawg thaum lub sijhawm tsim khoom, thiab tuaj yeem rov ua dua tom qab raug muab pov tseg, uas ua tau raws li qhov yuav tsum tau muaj ntawm kev tsim kho kom ruaj khov. Nyob rau tib lub sijhawm, nws cov yam ntxwv ua haujlwm ruaj khov nyob rau lub sijhawm ntev kuj tseem txo cov kev puas tsuaj ib puag ncig xws li cov khoom xau los ntawm cov kav dej puas tsuaj, muab kev lees paub rau ntsuab ntau lawm hauv kev lag luam.
Los ntawm tailings kev thauj mus los hauv mines mus rau acid thiab alkali cov khoom thauj hauv kev lag luam tshuaj, los ntawm kev kho cov hmoov tshauv hauv kev lag luam hluav taws xob mus rau kev thauj mus los hauv kev lag luam metallurgical, silicon carbide hnav-resistant pipelines maj mam hloov cov kav dej nrog lawv cov "nyuaj core" kev ua tau zoo thiab dhau los ua cov nyiam tshiab hauv kev lag luam tsheb thauj mus los. Nws tsis tsuas yog qhia txog kev nce qib ntawm cov khoom siv thev naus laus zis, tab sis tseem qhia txog kev txhim kho lub tswv yim ntawm cov lag luam nrhiav kev ua haujlwm zoo, txuag hluav taws xob, thiab kev tsim khoom zoo ib puag ncig.
Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, silicon carbide coj cov kav dej yuav ua lub luag haujlwm hauv ntau thaj chaw, muab kev txhawb nqa ntau dua rau kev ua haujlwm zoo ntawm kev lag luam ntau lawm thiab dhau los ua lub zog tseem ceeb hauv kev txhawb nqa kev lag luam zoo.
