Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
1. Qhov kawg tiv thaiv corrosion
Titanium cladding can instantly form a dense and stable oxide film (TiO₂) in the atmosphere or oxidizing medium, which is extremely resistant to chloride ions (Cl⁻), strong acids (such as sulfuric acid, nitric acid), alkali and seawater. Nyob rau hauv hnyav roj thiab roj ib puag ncig uas muaj H₂S / CO₂, tus nqi corrosion ntawm peb cov titanium steel puas vaj huam sib luag tuaj yeem qis li<0.001mm/year, which is more than 300% higher than that of ordinary carbon steel, ensuring that the equipment can achieve 30 years of maintenance-free operation on deep-sea platforms or chemical reactors.
2. Siab load-cov kabmob thiab lub zog muaj zog
Ua tsaug rau siab -lub zog steel (xws li Q345R, Q235B, thiab lwm yam) raws li lub hauv paus txheej, lub vaj huam sib luag sib xyaw muaj peev xwm zoo heev, thiab lub zog tensile tuaj yeem ncav cuag ntau dua lossis sib npaug li 500 MPa. Nyob rau hauv qhov xwm txheej ntawm kev kub siab thiab hnyav tonnage load, lub hauv paus hlau muab cov qauv kev txhawb nqa, thiab titanium txheej yog lub luag hauj lwm rau kev tiv thaiv - corrosion, thiab ob qho tib si ua hauj lwm ua ke kom ua tau raws li qhov tsim nyog lub zog ntawm cov hlab ntsha thiab cov khoom hnyav.
3. Zoo heev interface bonding kev ua tau zoo
Cov txheej txheem tshwj xeeb ntawm kev tawg vuam tso cai rau titanium / steel interface los tsim ib daim ntawv cog lus ntom "corrugated" metallurgical. Tom qab thib peb-kev kuaj pom zoo, lub zog shear ntawm peb cov khoom lag luam sib cuam tshuam deb tshaj li lub teb chaws tus qauv (feem ntau> 196MPa, thiab qee cov txheej txheem tuaj yeem ncav cuag ntau dua 330MPa), thiab tsis muaj kev pheej hmoo ntawm delamination lossis tawg hauv cov txheej txheem tom ntej coiling, stamping, vuam thiab thermal cycling txheej txheem.
4. Kev ua haujlwm zoo thiab kev tsim khoom
Txawm hais tias titanium laminate yog thinner, lub vaj huam sib luag ua kom pom tag nrho cov txheej txheem kev hloov pauv tau zoo:
Formability: Nws tuaj yeem dov, kub nias, spinning thiab lwm yam txias thiab kub ua kom tiav 180℃txias dabtsi yog khoov yam tsis muaj cracking.
Weldability: Txais cov qauv tsim tshwj xeeb (xws li npog phaj vuam txheej txheem), uas tuaj yeem vuam txheej txheej steel thiab txheej txheej titanium nyias kom tsis txhob nkig theem thiab ua kom yooj yim ntawm - qhov chaw sib dhos vuam thiab kev teeb tsa.

Core zoo
1. Kev lag luam tseem ceeb
Piv nrog cov ntshiab titanium los yog npib tsib xee-raws li alloys xws li Hastelloy, titanium hlau tawg puas vaj huam sib luag tuaj yeem txuag tau 70%-80% ntawm cov hlau tsis tshua muaj nqi kim. Ua tiav yuav luag "titanium" kev ua tau zoo ntawm tus nqi ntawm "steel" yog qhov kev daws teeb meem zoo kom txo tau qhov project nqi.

Core zoo
2. Designable asymmetrical qauv
Peb tuaj yeem hloov kho lub thickness ntawm lub laminate (feem ntau yog 1.5mm-12mm) thiab cov khoom thiab thickness ntawm lub hauv paus txheej raws li cov kev ua hauj lwm ntawm cov neeg siv. Nws tuaj yeem siv tsis tau tsuas yog nkoj daim hlau, thawv ntawv, qis- alloy high-strength steel, tab sis kuj stainless hlau ua lub hauv paus txheej kom ua tiav qhov zoo tshaj plaws match ntawm kev ua haujlwm thiab tus nqi.
3. Kev loj hlob ntsuab thiab ruaj khov
Los ntawm kev ncua kev pab cuam lub neej ntawm cov cuab yeej siv (ntau zaus ntawm cov hlau zoo tib yam), qhov zaus ntawm cov khoom siv hloov pauv vim yog corrosion raug txo, thiab cov pa roj carbon emissions thoob plaws hauv lub neej yuav raug txo. Nyob rau tib lub sijhawm, peb muaj kev ua tiav titanium nti recycling system, uas yog nyob rau hauv txoj kab nrog lub tswv yim kev taw qhia ntawm lub teb chaws ntsuab manufacturing.
