Hauv kev tsim khoom lag luam, cov kav dej zoo li "cov hlab ntsha" uas yog lub luag haujlwm rau kev thauj ntau yam xws li cov hlau nplaum, cov tshauv ya, thiab cov khoom siv tshuaj lom neeg. Tab sis cov xov xwm no feem ntau nqa cov khoom me me thiab yog corrosive. Cov kav dej ib txwm yuav sai sai no hnav thiab corroded, xav tau kev hloov pauv ntau zaus thiab ua rau muaj teeb meem kev nyab xeeb vim yog xau. Lubsilicon carbide hnav-resistant pipelinepeb yuav qhia hnub no yog "Pipeline Iron Man" yug los daws cov teeb meem no.
Tej zaum yuav muaj ib tug neeg nug tias, silicon carbide yog dab tsi? Hais yooj yim xwb, nws yog ib yam khoom inorganic uas muaj qhov nyuaj heev, thib ob tsuas yog pob zeb diamond thiab cubic boron nitride xwb. Nws muaj nyob rau hauv cov ntawv xuab zeb thiab cov log sib tsoo txhua hnub. Thaum cov khoom "tawv pob txha" no ua rau hauv cov kav dej, nws muaj kev tiv thaiv kev hnav zoo heev - ntsib cov khoom siv granular uas ntws ceev ceev, nws tuaj yeem tiv taus kev yaig zoo li cov cuab yeej ua rog, ua rau lub neej ua haujlwm ntawm cov kav hlau ib txwm ntev dua ntau zaus.
Ntxiv rau qhov zoo ntawm "kev tiv thaiv kev hnav", cov yeeb nkab silicon carbide hnav-resistant kuj muaj ob "kev txawj zais cia". Ib qho yog kev tiv thaiv corrosion. Txawm hais tias cov xov xwm kis tau yog acidic lossis alkaline, nws tuaj yeem "ruaj khov zoo li Mount Tai" thiab yuav tsis raug corroded thiab xeb zoo li cov yeeb nkab hlau; Qhov thib ob yog kev tiv thaiv kub siab, txawm tias thaum thauj cov khoom kub siab, cov yeeb nkab yuav tsis deform lossis tawg, ua rau nws muaj txiaj ntsig tshwj xeeb hauv kev ua haujlwm kub siab xws li metallurgy thiab hluav taws xob.
Qhov tseem ceeb tshaj plaws yog tias txawm hais tias hom kav dej no muaj kev ua tau zoo, kev teeb tsa thiab kev saib xyuas tsis nyuaj. Nws qhov hnyav sib dua li cov kav hlau ntawm tib qho kev qhia, ua rau kev thauj mus los thiab kev teeb tsa yooj yim dua; Ntxiv mus, vim nws muaj zog ruaj khov, yuav luag tsis tas yuav tsum tau saib xyuas thiab hloov pauv ntau zaus hauv theem tom qab, uas tuaj yeem pab cov lag luam txo qhov poob ntawm lub sijhawm tsis ua haujlwm thiab txo cov nqi ua haujlwm thiab kev saib xyuas.
Niaj hnub nim no, nrog rau qhov kev thov kom ua haujlwm tau zoo thiab muaj kev nyab xeeb hauv kev tsim khoom lag luam, cov kav dej silicon carbide hnav-resistant tau sai sai los ua nrov hauv kev tsuas, fais fab, tshuaj lom neeg thiab lwm yam teb. Nws tsis xav tau cov ntaub ntawv nyuaj los ua pov thawj, tab sis tsuas yog muaj qhov ua tau zoo ntawm "kev puas tsuaj tsawg dua, ruaj khov, thiab tsis txhawj xeeb", ua tus hlub tshiab hauv kev xa khoom lag luam. Yav tom ntej, hom 'Pipeline Iron Man' no yuav txuas ntxiv mus txhim kho, muab kev txhawb nqa kev tsim khoom ruaj khov rau ntau lub tuam txhab.
