Titanium qhov tshwj xeeb tsis kam tiv thaiv corrosion hauv dej hiav txwv tshaj li ntawm tag nrho lwm cov hlau. Nws muaj kev ruaj ntseg zoo kawg nkaus hauv cov dej hiav txwv zoo li qub thiab cov dej ntws siab, ua rau nws yog cov khoom siv zoo tshaj plaws rau cov tshuab desalination. Kev siv cov titanium hauv qhov no yog npaj kom nthuav dav.
Lub teeb nrog lub zog siab: Titanium muaj qhov ceev ntawm 4.51 g / cm³, siab dua aluminium tab sis qis dua hlau, tooj liab, thiab npib tsib xee. Txawm li cas los xij, nws boasts lub zog siab tshaj plaws-rau-qhov sib piv ntawm cov hlau, ua 3 zaug ntawm stainless hlau thiab 1.3 npaug ntawm aluminium alloys.
Zoo heev corrosion kuj: Titanium yog ib qho hlau uas muaj zog heev uas muaj qhov sib npaug qis, qhia txog kev tiv thaiv corrosion siab hauv xov xwm. Txawm li cas los xij, titanium nthuav tawm kev ruaj ntseg zoo kawg nkaus hauv ntau qhov chaw. Nws tiv taus corrosion hauv oxidative, nruab nrab, thiab tsis muaj zog txo cov xov xwm. Qhov no yog ntaus nqi rau titanium muaj zog affinity rau oxygen, uas ua rau tsim ib tug ntom, nrees adherent, thiab inert oxide zaj duab xis rau nws nto nyob rau hauv lub xub ntiag ntawm huab cua los yog oxygen-muaj xov xwm. Cov oxide zaj duab xis no tiv thaiv titanium puag los ntawm corrosion. Txawm tias cov khoom siv coj los ua kom kho tus kheej sai lossis rov tsim dua tshiab ntawm oxide zaj duab xis. Qhov no ua piv txwv titanium lub pronounced passivation nyiam. Cov oxide zaj duab xis khaws cov yam ntxwv no ntev npaum li qhov nruab nrab kub tseem qis dua 315 degree.
Kev ua tau zoo ntawm kev hloov pauv cua sov: Txawm hais tias titanium muaj qis thermal conductivity tshaj carbon steel thiab tooj liab, nws zoo heev corrosion kuj pab kom txo tau cov phab ntsa thickness. Ntxiv mus, hloov tshav kub ntawm titanium nto thiab chav tshwm sim los ntawm dropwise condensation, minimizing fouling thiab txo thermal kuj. Yog li ntawd, titanium nthuav tawm qhov ua tau zoo ntawm kev hloov hluav taws xob zoo.
Zoo kub tsis kam: Advanced titanium alloys tuaj yeem ua haujlwm rau lub sijhawm ntev ntawm qhov kub ntawm 600 degree lossis siab dua.
Cov tshuaj tiv thaiv kub kub zoo heev: Cov neeg sawv cev kub kub titanium alloys, xws li TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) , thiab Ti-2.5Zr-1.5Mo, nthuav tawm cov yam ntxwv muaj zog zoo dua nrog txo qhov kub thiab txias, thaum muaj cov yas deformation tsawg heev.
Lub zog tensile siab thiab lub zog tawm los: Cov cuab yeej no qhia qhov sib piv siab ntawm lub zog tensile rau lub zog tawm los, qhia tias txo cov yas deformation thaum lub sij hawm tsim titanium. Qhov sib piv tseem ceeb ntawm titanium qhov kev txwv tsis pub dhau thiab elastic modulus confers lub caij nplooj ntoos hlav-rov qab muaj peev xwm thaum tsim.
