Titanium valve feem ntau yog siv cov titanium hlau cov ntaub ntawv nyob rau hauv muaj zog corrosion ib puag ncig oxidation zaj duab xis muaj kev ruaj ntseg zoo thiab nws tus kheej-passivation muaj peev xwm, cov yam ntxwv no los tiv thaiv ntau yam mob hnyav corrosion. Txawm hais tias lub titanium valve tuaj yeem tiv taus qhov corrosion ntawm qhov chaw ua haujlwm nruab nrab, qhov tseem ceeb nyob hauv kev ruaj ntseg tshuaj ntawm "blunt oxide zaj duab xis" ntawm nws qhov chaw hauv nruab nrab corrosive. Rau nruab nrab, oxidizing, tsis muaj zog txo qhov nruab nrab ib puag ncig, "blunt oxide zaj duab xis" nws tus kheej muaj kev ruaj ntseg zoo. Rau kev txo cov corrosive media nrog kub lossis PH nqi qis, txhawm rau txhim kho kev ruaj ntseg ntawm nws "blunt oxide zaj duab xis", corrosion inhibitors (xws li huab cua, dej, hnyav hlau ions thiab anions, thiab lwm yam) tuaj yeem ntxiv, xws li titanium nto ion hloov kho kev kho mob, kev kho mob anodizing thiab lwm txoj hauv kev los txhim kho corrosion kuj thiab nto hardness ntawm "titanium" hauv kev txo cov xov xwm kom tau raws li qhov yuav tsum tau siv.
Titanium pob valve txais cov qauv saum toj kawg nkaus, uas txo qhov kev sib txuas bolts ntawm lub valve lub cev nws tus kheej nyob rau hauv cov xwm txheej ntawm kev kub siab thiab txoj kab uas hla loj, txhim kho kev ntseeg siab ntawm lub valve thiab tuaj yeem kov yeej lub zog ntawm lub cev qhov hnyav ntawm kev ua haujlwm ib txwm muaj. valve.
Titanium muaj qhov zoo ntawm lub teeb tshwj xeeb lub ntiajteb txawj nqus, siab zog, corrosion kuj, zoo siab tsis kam thiab lwm yam. Titanium kuj tseem muaj kev tiv thaiv zoo heev rau seawater corrosion thiab seawater yaig.
Muaj ntau yam khoom ntawm titanium valve
1, titanium ntom ntom hauv titanium valve yog me me, lub zog tshwj xeeb yog siab, qhov ceev ntawm titanium hlau yog 4.51g / cm3, siab dua txhuas thiab qis dua hlau, tooj liab, npib tsib xee.
2, Titanium valve corrosion kuj muaj zog.
3, titanium valve muaj cov cua kub zoo, thiab cov titanium alloy tshiab tuaj yeem siv tau ntev ntawm 600 degree lossis siab dua.
4, Titanium valve muaj qhov kub thiab txias tsis kam, titanium alloys TA7 (Ti-5Al-2.5Sn), TC4(Ti-6Al-4V) thiab Ti{{ 8}}.5Zr-1.5Mo yog cov titanium alloys kub, thiab lawv lub zog nce nrog qhov kub thiab txias, tab sis cov yas hloov me ntsis. Ua kom zoo ductility thiab toughness ntawm -196-253 degree qhov kub thiab txias, tsis txhob txias brittleness, yog cov khoom zoo tagnrho rau cov thawv kub kub, cov thawv ntim khoom thiab lwm yam khoom siv.
5, Titanium valve anti-damping kev ua tau zoo yog muaj zog, titanium hlau los ntawm txhua yam kev co, hluav taws xob kev co, piv nrog cov hlau, tooj liab hlau, nws tus kheej vibration attenuation lub sij hawm ntev.
6, Cov cuab yeej ntawm titanium no tuaj yeem siv los ua lub diav rawg. Titanium valve yog non-magnetic, tsis muaj tshuaj lom, titanium yog cov hlau tsis sib nqus, nyob rau hauv ib qho chaw sib nqus loj yuav tsis raug magnetized.
7, Lub zog tensile ntawm titanium valve yog nyob ze rau nws lub zog tawm los, thiab qhov kev ua tau zoo ntawm titanium qhia tau hais tias nws cov txiaj ntsig zoo (lub zog tensile / yield zog) siab, qhia tias cov khoom siv hlau titanium tsis zoo hauv cov yas deformation thaum tsim. Vim muaj qhov sib piv loj ntawm qhov kev txwv tsis pub dhau thiab qhov elastic modulus ntawm titanium, lub peev xwm ntawm titanium thaum lub sij hawm molding yog loj.
8, Titanium valve hloov hluav taws xob ua haujlwm tau zoo, txawm hais tias cov thermal conductivity ntawm titanium hlau yog qis dua cov hlau thiab tooj liab, tab sis vim qhov zoo tshaj plaws corrosion kuj ntawm titanium, yog li cov phab ntsa tuab tuaj yeem txo, thiab qhov kub thiab txias hloov pauv. txoj kev yog tee dej condensation, txo cov cua sov pab pawg, ib yam nkaus thiab cov nto tsis scale kuj yuav txo tau lub thermal kuj, yog li ntawd lub tshav kub hloov kev kawm ntawm titanium yog ho txhim kho.
9, Titanium valve suction kev ua tau zoo, titanium yog cov khoom siv tshuaj lom neeg, thaum kub kub tuaj yeem cuam tshuam nrog ntau lub ntsiab lus thiab cov khoom sib txuas. Titanium inhalation feem ntau yog hais txog cov tshuaj tiv thaiv nrog carbon, hydrogen, nitrogen thiab oxygen ntawm qhov kub thiab txias.
