Cov yam ntxwv ntawm Aggressive Chemical Environments
Cov tshuaj phem ib puag ncig feem ntau cuam tshuam nrog cov kua qaub muaj zog, alkalis, oxidizing cov neeg ua haujlwm, lossis cov txheej txheem rov ua haujlwm. Nyob rau hauv cov xwm txheej zoo li no, cov ntaub ntawv tsis tu ncua los ntawm corrosion, tshuaj tua kab mob, thiab degradation nto.
Titanium cua sov raj feem ntau xaiv rau cov cheeb tsam no vim lawv qhov kev tiv thaiv corrosion thiab muaj peev xwm los tsim cov txheej txheem oxide ruaj khov. Cov txheej tiv thaiv no ua qhov thaiv ntawm cov hlau substrate thiab cov tshuaj nyob ib puag ncig, txo qis cov tshuaj tiv thaiv thiab txo cov khoom poob.
Lub peev xwm los tswj cov txheej txheem thiab tshuaj lom neeg kev ncaj ncees nyob rau hauv cov xwm txheej no yog qhov tseem ceeb rau kev ua kom lub sijhawm ntev - ua haujlwm ruaj khov thiab ua haujlwm zoo thermal.
Passive Oxide Txheej thiab Corrosion Resistance
Ib qho tseem ceeb hauv titanium qhov kev ua tau zoo yog qhov tsim ntawm nyias txheej oxide txheej ntawm nws qhov chaw. Cov txheej no txhim kho ib txwm muaj thaum titanium raug rau cov pa oxygen-ib puag ncig thiab muab cov ntaub thaiv npog tiv thaiv kev tawm tsam tshuaj lom ntxiv.
Nyob rau hauv aggressive मीडिया, no passive txheej pab tiv thaiv kev sib cuag ncaj qha ntawm lub hauv paus hlau thiab reactive hom. Txawm hais tias qhov chaw muaj kev cuam tshuam los yog puas tsuaj me ntsis, oxide txheej muaj peev xwm hloov kho, rov ua kom muaj kev tiv thaiv lub sijhawm.
Qhov no tus kheej - kho tus yam ntxwv yog tshwj xeeb tshaj yog muaj nqis nyob rau hauv dynamic industrial systems qhov chaw tej zaum yuav muaj kev hnav, qhov hloov pauv, los yog cov dej txav uas tuaj yeem nthuav tawm cov khoom hauv paus.
Phab ntsa Thickness thiab tshuaj lom neeg tiv taus
Phab ntsa thickness contributes indirectly rau chemical durability. Lub phab ntsa tuab muab lub cev muaj zog ntau dua ntawm cov txheej txheem nruab nrab thiab cov txheej txheem ntawm lub raj, muab sijhawm ntxiv ua ntej qhov kev puas tsuaj tuaj yeem cuam tshuam kev ncaj ncees.
Txawm li cas los xij, tshuaj tiv thaiv tsis yog nyob ntawm tuab. Qhov saum npoo av, cov khoom zoo, thiab ib puag ncig txhua yam ua lub luag haujlwm tseem ceeb. Ib lub qhov dej zoo- cov phab ntsa nyias nyias tuaj yeem ua tau zoo hauv ntau qhov chaw nruj heev yog tias cov txheej txheem tsis zoo nyob ruaj khov thiab tsis zoo.
Hauv kev xyaum, cov phab ntsa tuab tuab feem ntau xaiv los sib npaug ntawm cov khoom siv dag zog, kev ua haujlwm thermal, thiab kev xav txog tshuaj lom neeg.
Surface Condition thiab Chemical Stability
Qhov zoo ntawm qhov chaw yog qhov tseem ceeb hauv cov txheej txheem tshuaj lom neeg. Qhov chaw du, huv si txo qhov chaw uas muaj tshuaj lom neeg tuaj yeem pib lossis nrawm. Qhov chaw ntxhib, ntawm qhov tod tes, tuaj yeem ntxiab cov khoom seem lossis tsim micro-ib puag ncig qhov chaw muaj kev xeb tuaj yeem tshwm sim.
Kev kho saum npoo kom zoo thiab ua tiav pab txhim kho kev ruaj ntseg ntawm cov oxide txheej thiab txo qhov kev pheej hmoo ntawm kev sib kis los yog qhov chaw tshuaj tiv thaiv. Nyob rau hauv siab -purity los yog rhiab heev cov txheej txheem tshuaj, tuav ib tug zoo ib yam thiab tsis xws luag -dawb nto yog ib qho tseem ceeb rau lub sij hawm ntev - ntseeg.
Cov txheej txheem deg passivation qee zaum siv los ntxiv dag zog rau cov txheej txheem tiv thaiv thiab xyuas kom muaj kev sib raug zoo nrog cov tshuaj lom neeg tshwj xeeb.
Qhov kub thiab txias cuam tshuam rau kev coj tus cwj pwm
Qhov kub thiab txias plays lub luag haujlwm tseem ceeb hauv chemical reactivity. Raws li qhov kub thiab txias, cov tshuaj tiv thaiv feem ntau nrawm dua, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm qhov chaw corrosive.
Nyob rau hauv titanium cua sov raj, elevated tej yam kev mob yuav tsum tau ua tib zoo tswj xyuas kom meej tias cov tiv thaiv oxide txheej tseem ruaj khov. Thaum titanium ua tau zoo nyob thoob plaws qhov kub thiab txias, huab cua huab cua yuav xav tau kev tsim qauv ntxiv kom tswj tau ntev - lub sij hawm tsis kam.
Thermal gradients kuj tuaj yeem cuam tshuam cov cwj pwm ntawm cov tshuaj lom neeg los ntawm kev tsim cov cheeb tsam hauv cheeb tsam ntawm ntau dua reactivity. Kev faib tawm qhov kub tsis sib xws pab tiv thaiv xws li kev nrawm nrawm ntawm cov txheej txheem tshuaj.
Flow Conditions thiab Chemical Distribution
Hauv cov kua dej-raws li cov tshuab, ntws tus cwj pwm cuam tshuam li cas cov tshuaj cuam tshuam nrog cov cua sov. Uniform flow kom ntseeg tau tias cov tshuaj nruab nrab yog sib npaug ntawm cov raj, tiv thaiv cov cheeb tsam ntawm cov hom reactive.
Kev faib tawm tsis zoo tuaj yeem ua rau thaj chaw stagnation uas cov tshuaj tseem nyob hauv kev sib cuag nrog qhov ntev. Cov tshuaj no yuav muaj kev sib cuam tshuam tshuaj lom neeg ntau dua piv rau cov cheeb tsam uas muaj dej ntws.
Kev tswj kom ruaj khov thiab ua haujlwm zoo ib yam yuav pab txo qis hauv cheeb tsam thiab txhawb kev sib cuam tshuam tshuaj lom neeg ntau dua thoob plaws lub cev.
