Hauv kev tsim khoom lag luam, cov raj xa dej zoo li "cov hlab ntsha" ntawm cov khoom siv, lub luag haujlwm thauj khoom "kub tempered" xws li xuab zeb, pob zeb, thiab cov roj kub kub. Sij hawm dhau mus, cov phab ntsa sab hauv ntawm cov kav dej zoo tib yam tau yooj yim hnav thiab tuaj yeem xau, xav tau kev saib xyuas thiab hloov kho, thiab tseem tuaj yeem ncua kev ua tiav. Qhov tseeb, ntxiv ib txheej ntawm "cov khaub ncaws tiv thaiv tshwj xeeb" rau hauv cov kav dej tuaj yeem daws qhov teeb meem, uas yogsilicon carbide pipeline hauv ob sab phlupeb yuav tham txog hnub no.
Qee tus neeg yuav nug, dab tsi yog lub hauv paus chiv keeb ntawm silicon carbide ceramics uas suab zoo heev "hardcore"? Yooj yim muab tso, nws yog cov khoom siv ceramic ua los ntawm cov khoom siv tawv xws li silicon carbide los ntawm cov txheej txheem tshwj xeeb, thiab nws qhov tseem ceeb tshaj plaws yog "durability": nws qhov tawv yog qhov thib ob rau pob zeb diamond, thiab nws tuaj yeem tiv taus qhov yaig ntawm cov xuab zeb thiab pob zeb thiab cov ntaub ntawv corrosive tsis tu ncua, tsis zoo li cov hlau zoo tib yam liners uas nquag xeb thiab hnav, thiab nws kuj muaj ntau qhov kub thiab txias.
Lub hauv paus ntawm kev txhim kho silicon carbide hauv ob sab phlu hauv cov kav dej yog txhawm rau ntxiv "txhim kho qhov thaiv" rau sab hauv phab ntsa. Thaum txhim kho, tsis tas yuav ua kom muaj zog loj. Feem ntau ntawm cov sij hawm, prefabricated silicon carbide ceramic pieces yog sib txuas rau sab hauv phab ntsa ntawm lub raj xa dej nrog cov nplaum tshwj xeeb los tsim cov txheej txheem tiv thaiv tiav. Qhov txheej ntawm 'barrier' no yuav tsis zoo li tuab, tab sis nws txoj haujlwm yog qhov tshwj xeeb:
Ua ntej, nws yog 'tag nrho hnav tsis kam'. Txawm hais tias nws yog thauj cov ore hais nrog cov npoo ntse lossis kev kub ceev ntws slurry, qhov saum npoo ntawm silicon carbide hauv ob sab phlu yog tshwj xeeb tshaj yog du. Thaum cov khoom hla dhau, qhov kev sib txhuam me me, uas tsis tsuas yog tsis ua rau lub hauv ob sab phlu, tab sis kuj txo qhov kev tiv thaiv thaum lub sij hawm thauj khoom, ua rau kev thauj mus los smoother. Cov kav xa dej zoo ib yam yuav xav tau kev saib xyuas tom qab ib nrab xyoo ntawm kev hnav thiab tsim kua muag, thaum cov kav dej nrog silicon carbide hauv ob sab phlu tuaj yeem txuas ntxiv lawv lub neej kev pab cuam, txo qhov hassle thiab tus nqi ntawm kev hloov cov yeeb nkab rov qab.
Tom qab ntawd muaj "corrosion tsis kam thiab kub kub ua haujlwm dual kab". Hauv ntau qhov xwm txheej ntawm kev lag luam, cov khoom siv thauj khoom nqa cov khoom corrosive xws li acid thiab alkali, thiab qhov kub tsis qis. Cov ntaub ntawv zoo tib yam yog corroded thiab tawg, los yog deformed los ntawm kub kub ci. Tab sis silicon carbide ceramics lawv tus kheej muaj cov tshuaj ruaj khov thiab tsis ntshai ntawm cov kua qaub thiab alkali yaig. Txawm tias thaum raug kub ntawm ntau pua degrees Celsius, lawv tuaj yeem tswj tau ib daim ntawv ruaj khov, ua rau lawv tsim nyog rau kev siv cov kav dej hauv "qhov chaw hnyav" xws li tshuaj lom neeg, metallurgical, thiab mining.
Lwm lub ntsiab lus tseem ceeb yog "kev txhawj xeeb thiab tsis muaj zog". Cov kav dej uas muaj silicon carbide tsis tas yuav tsum tau kaw ntau zaus rau kev saib xyuas, thiab tseem yooj yim rau kev tswj hwm - qhov saum npoo tsis yooj yim rau scaling lossis cov khoom dai, thiab tsuas yog yuav tsum tau ntxuav me ntsis tsis tu ncua. Rau cov lag luam, qhov no txhais tau tias txo qhov kev pheej hmoo ntawm kev cuam tshuam kev tsim khoom thiab txuag nyiaj ntau ntawm kev ua haujlwm thiab cov nqi khoom siv, uas yog sib npaug rau "kev teeb tsa ib zaug, kev txhawj xeeb mus sij hawm ntev".
Qee tus neeg yuav xav tias cov ntaub ntawv zoo li no tseem kim heev? Qhov tseeb, xam "cov nyiaj mus sij hawm ntev" yog qhov tseeb: txawm hais tias tus nqi pib ntawm cov txheej txheem qis qis, nws yuav tsum tau hloov txhua peb mus rau tsib lub hlis; Thawj qhov peev txheej rau silicon carbide hauv ob sab phlu yog me ntsis siab dua, tab sis nws tuaj yeem siv tau ntau xyoo, thiab tus nqi nruab nrab ntawm ib hnub yog qis dua. Tsis tas li ntawd, nws tuaj yeem zam kev poob los ntawm kev puas tsuaj los ntawm cov kav xa dej, thiab tus nqi ua tau zoo yog qhov siab heev.
Niaj hnub no, silicon carbide pipeline hauv ob sab phlu tau maj mam dhau los ua "kev daws teeb meem" rau kev tiv thaiv kev lag luam, los ntawm cov tailings conveying pipelines hauv mines, mus rau cov khoom siv corrosive pipelines hauv kev lag luam tshuaj, mus rau high-temperature flue gas pipelines hauv kev lag luam fais fab, nws muaj peev xwm pom tau. Yooj yim muab tso, nws zoo li "tus kheej lub cev tiv thaiv" ntawm cov kav dej, ntsiag to saib xyuas kev ua haujlwm zoo ntawm kev tsim khoom lag luam nrog nws tus kheej hardness thiab durability - qhov no kuj yog vim li cas ntau thiab ntau lub tuam txhab txaus siab los muab cov kav dej nrog "cov khaub ncaws tiv thaiv tshwj xeeb".
