Thaum qhov kub ntawm cov roj hydrogen tsawg dua 350 ℃, 20 # cov kav hlau tsis muaj qhov sib txuas feem ntau siv rau cov roj hydrogen nrog lub siab ntawm 1.0MPa. Thaum qhov kub ntawm cov roj hydrogen nyob hauv qhov ntau ntawm 351-400 ℃, 15CrMo lossis 12CrMo cov kav hlau tsis muaj qhov sib txuas feem ntau siv.
(4) Kev cuam tshuam ntawm cov khoom siv tshuaj lom neeg nruab nrab
Siv cov yeeb nkab sib txawv thauj cov khoom sib txawv. Qee cov khoom sib txawv yog qhov nruab nrab thiab feem ntau tsis xav tau cov khoom siv siab. Cov yeeb nkab hlau carbon ib txwm siv tau; Qee cov khoom sib txawv yog acidic lossis alkaline, yog li nws yog qhov tsim nyog los xaiv cov yeeb nkab uas tiv taus acid lossis alkali. Cov kev cai rau kev siv cov yeeb nkab yog txawv ntawm cov kua qaub thiab cov hauv paus muaj zog thiab tsis muaj zog. Tib cov kua qaub lossis hauv paus, nrog cov concentration sib txawv, kuj muaj cov kev cai sib txawv rau cov khoom siv ntawm cov yeeb nkab. Yog tias thauj dej thiab pa dej, cov yeeb nkab ua los ntawm cov khoom siv hlau carbon txaus. Hauv cov nroj tsuag urea, cov yeeb nkab hlau stainless feem ntau siv rau kev thauj cov pa roj carbon dioxide, vim tias cov pa roj carbon dioxide tsim cov pa roj carbon dioxide thaum nws ntsib dej, uas muaj cov teebmeem corrosive rau cov yeeb nkab hlau dav dav. Yog tias tsim cov kua qaub sulfuric, cov yeeb nkab hlau carbon tuaj yeem siv tau, thaum rau cov kua qaub sulfuric dilute, cov yeeb nkab hlau carbon tsis tuaj yeem siv vim tias cov kua qaub sulfuric dilute thiab cov hlau carbon tuaj yeem ua rau cov tshuaj lom neeg thiab corrode cov hlau carbon. Yog li ntawd, cov yeeb nkab txhuas tawv tuaj yeem siv tau.
(5) Qhov cuam tshuam ntawm kev ua haujlwm ntawm cov yeeb nkab nws tus kheej
Ntxiv rau qhov ua haujlwm ntawm kev xa cov khoom nruab nrab, qee cov kav dej kuj muaj qhov ua haujlwm ntawm kev nqus dej thiab coefficient ntawm thermal expansion. Nyob rau hauv cov xwm txheej ua haujlwm, lawv tuaj yeem txav mus los ntau zaus, xws li cov roj av liquefied, oxygen thiab acetylene roj rau kev siv pej xeem ntawm qhov chaw ntim lub raj mis. Cov kav hlau hlau siab siab woven roj hmab feem ntau siv rau cov kav dej, es tsis txhob siv cov kav hlau tawv uas tsis yooj yim txav mus los.
(6) Qhov cuam tshuam ntawm kev poob siab
Tom qab xaiv cov khoom siv yeeb nkab thawj zaug, yuav tsum xam qhov siab ntawm cov yeeb nkab kom paub seb lub raj sab hauv puas loj. Xam qhov siab ntawm cov yeeb nkab kom pom tias cov khoom siv xaiv puas ua tau raws li qhov yuav tsum tau ua. Tshwj xeeb tshaj yog thaum xaiv cov yeeb nkab yas thawj zaug, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov siab ntawm cov yeeb nkab.
Rau kev xam cov kav dej siab, hauv kev tsim qauv engineering, kev sib npaug ntawm cov khoom siv, kev sib npaug ntawm lub zog thiab kev xam cov khoom siv feem ntau yog ua raws li qhov ntsuas ntau lawm los txiav txim siab ua ntej txog cov khoom ntws. Nrog rau kev xa mus rau cov ntaub ntawv cuam tshuam, xav txog tus nqi ntws ntawm cov khoom siv, xam lub cheeb sab hauv ntawm cov kav dej, xyuas phau ntawv lossis tus qauv, thiab xaiv cov kav dej tus qauv. Lub cheeb sab hauv ntawm cov kav dej tus qauv feem ntau xaiv yuav tsum sib npaug lossis loj dua me ntsis ntawm lub cheeb sab hauv uas tau xam ntawm cov kav dej. Xam qhov poob siab ntawm cov kav dej dua.
