Kev Txhais Lus:cov yeeb nkab hlau kub tsawgyog nruab nrabcov hlau ua los ntawm cov pa roj carbonCov kav dej hlau txias thiab kub thiab qis kub muaj kev ua tau zoo, cov khoom siv kho tshuab zoo, tus nqi qis thiab cov peev txheej dav, yog li lawv tau siv dav. Nws qhov tsis muaj zog tshaj plaws yog tias cov haujlwm ua haujlwm nrog qhov nyuaj tsawg, qhov loj ntawm qhov seem thiab qhov xav tau siab yuav tsum tsis txhob siv.
Lubcov yeeb nkab hlau tsis muaj qhov kub thiab txiastuaj yeem ua haujlwm hauv qhov chaw txias heev ntawm - 45 ~ - 110 ℃. Qhov zoo tshaj plaws ntawm cov yeeb nkab hlau tsis muaj qhov kub thiab txias yog tias nws tuaj yeem ua haujlwm hauv qhov chaw qis heev, uas tsis muaj qhov sib piv nrog cov yeeb nkab hlau tsis muaj qhov kub thiab txias. Cov yeeb nkab hlau tsis muaj qhov kub thiab txias muaj lub zog zoo thiab qhov kub thiab txias toughness, thiab siv dav hauv kev tsim cov khoom siv kub thiab txias hauv roj av, tshuaj lom neeg, chiv thiab lwm yam lag luam nrog qhov kub thiab txias ua haujlwm ntawm - 45 ~ - 110 ℃. Nrog rau kev txhim kho ntawm cov lag luam cuam tshuam, cov kev xav tau rau cov ntaub ntawv tsis yog tsuas yog txwv rau cov kev xav tau yooj yim xws li cov khoom siv kho tshuab thiab cov khoom vuam, tab sis kuj tseem muaj cov kev xav tau rau H2S corrosion tsis kam ntawm cov yeeb nkab kub thiab txias.
Cov yeeb nkab hlau tsis muaj qhov kub thiab txiassiv tau rau kev tsim cov kav dej hauv qhov chaw kub tsawg. Muaj ob txoj hauv kev: kos duab txias thiab dov kub. Los ntawm qhov kev xav ntawm kev tsim hlau, kev ua hlau, dov, kev kho cua sov thiab lwm yam txheej txheem ntawm cov yeeb nkab hlau tsis muaj qhov kub tsawg yuav tsum tau tswj hwm nruj me ntsis kom ntseeg tau tias cov yeeb nkab hlau tsis muaj qhov kub tsawg muaj lub zog zoo, tawv thiab tiv taus corrosion. Rau cov kev xav tau ntawm cov yeeb nkab hlau tsis muaj qhov kub tsawg, lub koom haum tsim khoom thiab tus nqi tsim khoom ntawm cov yeeb nkab hlau yuav tsum tau txiav txim siab tag nrho. Kev tsim cov khoom sib xyaw ntawm cov yeeb nkab hlau tsis muaj qhov kub tsawg yuav tsum xyuas kom meej tias cov khoom muaj lub zog tsim nyog, siab qis kub, thiab cov txheej txheem kho cua sov yooj yim weldability zoo thiab tiv taus hydrogen-induced cracking.
