Hauv cov xwm txheej ntawm cov chaw ua haujlwm hauv Hoobkas, kev khawb av, lossis kev xa hluav taws xob, muaj ib hom kav dej uas "tsis paub" txhua xyoo puag ncig tab sis nqa lub luag haujlwm hnyav - lawv feem ntau thauj cov xov xwm nrog cov khoom siv sib txhuam muaj zog xws li xuab zeb, slurry, hmoov thee, thiab lwm yam. Cov kav dej ib txwm yuav raug hnav dhau hauv lub sijhawm luv luv, uas tsis tsuas yog cuam tshuam rau kev ua haujlwm zoo ntawm kev tsim khoom tab sis kuj ua rau muaj kev phom sij rau kev nyab xeeb. Kev tshwm sim ntawmsilicon carbide hnav-resistant yeeb nkabyog qhov tseeb los daws qhov teeb meem kev lag luam no, ua tus saib xyuas "hard core" hauv kev thauj mus los nyuaj.
Dab tsi yog silicon carbide hnav-resistant pipeline?
Hauv lus yooj yim, cov kav dej silicon carbide hnav-resistant yog cov kav dej thauj khoom ua los ntawm kev sib xyaw silicon carbide ua cov khoom siv hnav-resistant tseem ceeb nrog cov kav dej hlau (xws li cov kav dej hlau) los ntawm cov txheej txheem tshwj xeeb.
Tej zaum yuav muaj ib tug neeg nug tias, silicon carbide yog dab tsi? Nws yog ib yam khoom siv tsis yog hlau uas tsis yog inorganic uas muaj zog heev, thib ob tsuas yog pob zeb diamond xwb. Ntau daim ntawv xuab zeb thiab cov log sib tsoo uas peb pom hauv lub neej txhua hnub yog ua los ntawm silicon carbide. Siv cov kws tshaj lij 'hnav-resistant' los ua cov kab hauv cov kav dej tuaj yeem ua rau lawv muaj zog hnav tsis kam.
Piv nrog cov kav hlau ib txwm muaj thiab cov kav hlau pob zeb cam khwb cia, qhov zoo ntawm cov kav hlau silicon carbide hnav-resistant yog "ob qho tib si sab hauv thiab sab nraud kho": cov txheej silicon carbide sab hauv yog lub luag haujlwm rau kev tiv thaiv kev yaig thiab hnav ntawm cov khoom nruab nrab, thaum cov txheej hlau sab nraud ua kom muaj zog tag nrho thiab lub zog compressive ntawm cov kav dej. Kev sib xyaw ua ke ntawm ob qho tsis yog tsuas yog daws qhov teeb meem ntawm kev hnav-resistant, tab sis kuj suav nrog kev nyab xeeb thiab kev ntseeg siab ntawm kev siv hauv kev lag luam.
Vim li cas nws thiaj li 'tiv taus' qhov chaw ib puag ncig hnyav?
Qhov ruaj khov ntawm cov kav dej silicon carbide hnav-resistant feem ntau yog los ntawm cov yam ntxwv ntawm cov khoom siv silicon carbide nws tus kheej:
Kev tiv thaiv kev hnav zoo heev: Raws li tau hais ua ntej, silicon carbide muaj qhov nyuaj heev, thiab nws qhov kev hnav ntawm qhov chaw qeeb heev thaum muaj kev yaig ntev los ntawm cov khoom siv granular xws li slurry thiab xuab zeb. Piv rau cov kav hlau ib txwm, lawv lub neej kev pabcuam feem ntau tuaj yeem ntev dua ntau zaus lossis ntau dua kaum zaug, txo qhov zaus thiab tus nqi ntawm kev hloov kav dej.
Kev tiv taus kub thiab qis thiab kev tiv taus corrosion: Ntxiv rau kev hnav tsis kam, silicon carbide kuj tseem tuaj yeem hloov kho rau ntau qhov kub thiab txias, thiab tuaj yeem ua haujlwm ruaj khov hauv cov chaw ib puag ncig txij li kaum tawm degrees Celsius mus rau ntau pua degrees Celsius. Tib lub sijhawm, nws kuj muaj kev tiv taus zoo rau cov xov xwm corrosive xws li acid thiab alkali, uas ua rau nws "muaj peev xwm" hauv cov xwm txheej kev thauj mus los nyuaj hauv kev lag luam xws li tshuaj lom neeg thiab metallurgical.
Kev thauj khoom ruaj khov: Vim yog qhov du ntawm cov silicon carbide lining, qhov tsis kam ntawm cov khoom nruab nrab ntws hauv cov kav dej yog qis, ua rau nws tsis yooj yim rau kev thaiv. Qhov no tsis yog tsuas yog ua kom muaj kev thauj mus los ruaj khov, tab sis kuj txo cov sijhawm tsis ua haujlwm los ntawm kev ntxuav cov kav dej.
Nws qhia nws cov txuj ci nyob qhov twg?
Txawm hais tias nws suab zoo li "kev tshaj lij", daim ntawv thov ntawm cov kav dej silicon carbide hnav-resistant yog qhov ze heev rau peb cov khoom tsim thiab lub neej:
Hauv kev lag luam mining thiab metallurgical, nws yog siv los thauj cov mineral slurry los ntawm kev mining thiab cov khib nyiab los ntawm smelting, thiab raug kev hnav thiab tsim kua muag los ntawm cov khoom siv high concentration particulate media;
Hauv kev lag luam fais fab, nws yog ib qho tseem ceeb rau kev thauj cov hmoov thee hauv cov chaw tsim hluav taws xob thermal, kom ntseeg tau tias muaj roj boiler ruaj khov;
Hauv cov ntaub ntawv tsim kho thiab kev lag luam tshuaj lom neeg, nws tuaj yeem thauj cov khoom siv cement, cov ntaub ntawv tshuaj lom neeg, thiab lwm yam, kom daws tau qhov hnav thiab xeb me ntsis ntawm cov xov xwm sib txawv.
Nws tuaj yeem hais tias nyob rau hauv txhua qhov chaw lag luam uas xav tau kev thauj mus los ntawm cov xov xwm nrog kev tiv thaiv kev hnav thiab kev ua haujlwm nyuaj, qhov muaj cov kav dej silicon carbide hnav-resistant tuaj yeem pom. Nws muab cov lus lees paub tseem ceeb rau kev ua haujlwm tas mus li thiab ua haujlwm tau zoo ntawm kev tsim khoom lag luam nrog nws tus kheej "hardcore", thiab kuj tau dhau los ua ib feem tseem ceeb ntawm cov txheej txheem kev thauj khoom niaj hnub.
