Cov hlab ntsha siab yog ib hom thawv uas tsim los tuav cov kua lossis cov pa roj ntawm qee qhov siab thiab kub. Nws yog dav siv nyob rau hauv ntau yam lag luam, xws li roj thiab roj, tshuaj, thiab petrochemical industries. Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov hlab ntsha siab yog lawv cov kev tsim kho zoo, uas ua kom lawv muaj zog, ruaj khov, thiab muaj peev xwm tiv taus qhov kub thiab txias.
Lub tshuab ua haujlwm ntawm cov hlab ntsha siab yog qhov tseem ceeb rau lawv txoj kev nyab xeeb thiab kev ua haujlwm. Cov hlab ntsha siab zoo yog tsim los ntawm cov ntaub ntawv muaj zog, xws li carbon steel, stainless hlau, thiab txhuas. Cov ntaub ntawv no yog xaiv rau lawv lub zog, toughness, thiab tsis kam mus corrosion. Tsis tas li ntawd, cov txheej txheem tsim khoom muaj cov txheej txheem tswj xyuas nruj kom ntseeg tau tias lub nkoj ua tau raws li cov qauv thoob ntiaj teb.
Kev tiv thaiv corrosion ntawm cov hlab ntsha siab yog lwm qhov tseem ceeb ntawm lawv cov qauv tsim. Kev kub siab thiab kub nyob rau hauv cov hlab ntsha no tuaj yeem ua rau corrosion, uas tuaj yeem ua rau cov dej xau thiab lwm yam kev nyab xeeb. Cov hlab ntsha siab zoo yog tsim los ntawm cov khoom siv corrosion-resistant uas muaj peev xwm tiv taus cov tshuaj lom neeg hnyav. Piv txwv li, stainless hlau muaj zoo heev corrosion kuj mus rau ntau yam ntawm acids thiab bases, ua rau nws yog ib tug nrov khoom siv nyob rau hauv siab hlab ntsha.
Cov hlab ntsha siab kuj tau tsim los tiv thaiv qhov kub thiab txias. Hauv qee qhov kev lag luam, xws li kev lag luam petrochemical, cov hlab ntsha siab tau raug rau qhov kub thiab txias uas tuaj yeem ncav cuag 600 degrees Celsius. Cov hlab ntsha siab zoo yog tsim los ntawm cov khoom siv uas muaj peev xwm tiv taus qhov kub siab no yam tsis muaj degrading lossis ua tsis tiav. Piv txwv li, npib tsib xee-raws li alloys feem ntau yog siv rau hauv kev tsim cov hlab ntsha siab vim lawv qhov kub thiab txias zog thiab tiv thaiv oxidation.
Hauv kev xaus, cov hlab ntsha siab zoo yog qhov tseem ceeb rau kev tswj xyuas kev nyab xeeb thiab kev ua haujlwm zoo hauv ntau yam kev lag luam. Lawv tau tsim los nrog cov ntaub ntawv muaj zog, tsim los ntawm cov txheej txheem tswj kev ua tau zoo, thiab muaj peev xwm tiv taus siab, kub, thiab corrosion. Los ntawm kev ua kom cov hlab ntsha siab tau ua rau cov qauv siab tshaj plaws, peb tuaj yeem txo qhov kev pheej hmoo ntawm kev sib tsoo thiab ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov txheej txheem kev lag luam.
