Piv nrog cov pa fasteners xws li stainless hlau thiabcarbon steel screws, titanium alloy screws qhia tau zoo heev cov khoom siv kho tshuab thiab ib puag ncig adaptability. Lawv yog cov nyiam fasteners rau siab - khoom siv kawg, aerospace, marine ua hauj lwm tej yam kev mob thiab precision instruments. Kab lus no piav qhia txog qhov tseem ceeb ntawm kev ua tau zoo, cov txheej txheem kho cua sov thiab ya raws - pov thawj tiv thaiv kev ntsuas ntawm titanium alloy screws.
1. Core Performance Advantages ntawm
1. Ultra-siab Specific Strength
Titanium alloy nta lub zog tshwj xeeb heev (qhov sib piv ntawm lub zog tensile rau qhov ntom). Nws lub zog tensile ncav cuag 100 ~ 140kgf / mm², thaum nws qhov ceev tsuas yog 60% ntawm cov hlau. Nyob rau hauv tib lub zog yuav tsum tau, titanium alloy screws yog sib dua nyob rau hauv qhov hnyav, uas zoo paub txog lub teeb yuag ntawm cov khoom siv.
2. Zoo heev nruab nrab-kub muaj zog
Titanium alloy muaj qhov zoo dua siab -kub tsis kam tshaj aluminium alloy. Nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm 450℃~ 500℃thiab tswj lub zog zoo ib yam, ua rau nws tsim nyog rau cov khoom siv fastening nyob rau hauv ntau yam nruab nrab thiab siab - kub ua hauj lwm tej yam kev mob.
3. Superior Corrosion Resistance
When exposed to the atmosphere, a dense and uniform inert oxide protective film will instantly form on the surface of titanium alloy, effectively isolating corrosive media. Nws ua tau zoo heev nyob rau hauv nruab nrab thiab oxidizing ib puag ncig xws li atmospheric tej yam kev mob, seawater, humid chlorine gas thiab chloride daws. Txawm li cas los xij, nws cov kev tiv thaiv corrosion kuj txo qis hauv kev txo cov kua qaub tawm xws li hydrochloric acid.
4. Tsis tshua muaj siab -kub Toughness
Tsawg-interstitial titanium alloys (xws li TA7) muaj qhov ua tau zoo heev - kub. Lawv tuaj yeem tuav cov yas zoo ntawm qhov ultra- qhov kub thiab txias ntawm -253℃yam tsis muaj qhov txias txias thiab tawg, thiab muaj feem xyuam rau cov khoom siv cryogenic thiab cov haujlwm ua haujlwm kub qis.
5. Lub cev muaj zog zoo heev
Titanium alloy screwsmuaj cov qauv qis elastic, tsis tshua muaj thermal conductivity thiab tsis yog{0}} cov khoom sib nqus yam tsis muaj kev cuam tshuam sib nqus, uas yog tsim rau cov xwm txheej tshwj xeeb xws li cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv kho mob.
6. Siab hardness thiab muaj zog cov qauv ruaj khov
Titanium alloy muaj siab zuag qhia tag nrho hardness thiab muaj zog extrusion thiab hnav tsis kam. Nws tsis yooj yim rau deform thaum lub sij hawm ntev - kev pab cuam lub sij hawm thiab tuav tswj kev ruaj ntseg zoo zoo li lub fastener.
7. Kev ua haujlwm thermal zoo
Titanium alloy muaj qhov nruab nrab stamping kev ua tau zoo ntawm chav tsev kub tab sis zoo heev thermoplasticity ntawm qhov kub thiab txias. Ntau yam tshwj xeeb tshwj xeeb- zoo li tus ntsia hlau tuaj yeem ua tiav los ntawm kev kub forging thiab kub sib sau nrog ruaj khov molding zoo.
2. Kev kho cua sov txheej txheem ntawmTitanium Alloy Screws
Kho cov txheej txheem kev kho cua sov tuaj yeem hloov cov txheej txheem sab hauv ntawm titanium alloy kom ua tau raws li cov kev xav tau sib txawv rau lub zog, toughness thiab qaug zog ua haujlwm. Cov qauv zoo equiaxed xa cov yas zoo, thermal stability thiab qaug zog; cov qauv acicular muab lub zog muaj zog ntau dua, nkag siab lub zog thiab tawg toughness; sib xyaw equiaxed thiab acicular lug ua tiav qhov zoo tshaj plaws kev ua haujlwm zoo tshaj plaws.
Cov txheej txheem kev kho cua sov feem ntau rau cov titanium alloys suav nrog annealing, kev daws teeb meem thiab kev kho kev laus. Annealing feem ntau yog siv los tshem tawm cov kev ntxhov siab sab hauv, txhim kho plasticity thiab cov qauv kev ruaj ntseg, thiab txhim kho kev ua tau zoo. Rau cov pa alloys thiab ( + ) alloys, qhov kub ntawm annealing yog teem rau 120℃~ 200℃hauv qab no theem hloov point ntawm ( + ) → .
Kev daws thiab kev laus kev kho mob yog cov txheej txheem ntxiv dag zog. Kev ua kom txias sai sai ntawm qhov kub siab tau txais cov qauv metastable, thiab tom qab ntawd nruab nrab - qhov kub thiab txias preservation txhawb nqa nag lossis daus ntawm dispersed thib ob- theem hais los ntawm cov theem metastable kom ntxiv dag zog rau cov hlau. Lub quenching kub ntawm (+) alloys yog 40℃~ 100℃hauv qab ntawm theem hloov pauv, thaum lub metastable alloys yog 40℃~ 80℃saum toj no theem hloov point. Cov pa kub kub yog tswj ntawm 450℃~ 550 degree.
Txhawm rau ua kom tau raws li cov kev cai tshwj xeeb ntawm kev ua haujlwm, kev tsim kho kev lag luam xws li muab ob npaug rau annealing, isothermal annealing, kev kho cua sov thiab kev kho thermomechanical tuaj yeem siv los ua kom zoo dua qhov kev ua tau zoo ntawm titanium alloy screws.
3. Moisture -pov thawj Kev Ua Haujlwm thiab Kev Tiv Thaiv Kev Ntsuas ntawm Titanium Alloy Screws
Titanium alloy nws tus kheej muaj cov dej noo zoo heev - pov thawj, damp - pov thawj thiab xeb- pov thawj muaj peev xwm, thiab yuav tsis xeb lossis oxidize thiab ua tsis tiav hauv huab cua ntub thiab siab - av noo ib puag ncig. Txawm li cas los xij, kev kho kev tiv thaiv saum npoo tseem yuav tsum tau ua kom ntev ntev - kev pab cuam nyob rau hauv qhov kub thiab txias siab, tshuaj tsuag ntsev, kua qaub thiab alkali corrosive ib puag ncig kom ntev kev pab cuam lub neej thiab stabilize cov tsos thiab kev ua tau zoo. Cov kev tiv thaiv ib txwm muaj raws li hauv qab no:
1. Kev xaiv cov xim tiv thaiv insulating: Ua ntej epoxy resin thiab polyurethane impregnating xim tsis muaj volatile acid. Solvent- xim dawb yog pom zoo rau cov khoom siv vibrating kom tsis txhob xim xeb thiab tev.
2. Kev tswj cov txheej txheem curing: Thaum siv melamine alkyd xim rau kev tiv thaiv, nruj me ntsis tswj qhov curing tsis. Qhov kub curing yuav tsum yog me ntsis siab dua 130℃nrog lub sijhawm kho tsis pub tsawg tshaj 180 feeb. Tshwj xeeb tshaj yog nyob rau lub caij kub thiab av noo, cov txheej txheem kho kom tiav yuav tsum tau ua los tiv thaiv cov xim tev thiab noo noo rov tshwm sim los ntawm kev kho tsis tiav.
3. Nto tiv thaiv- kev kho corrosion sealing: Ntau yam txheej txheem sealing tau txais yuav los ua txheej txheej tiv thaiv ntawm qhov chawtitanium alloy screws, cais tawm sab nraud ya raws thiab corrosive media, inhibiting corrosion tshwm sim thiab ntxiv kev txhim kho kev tiv thaiv nyob rau hauv siab - av noo ua hauj lwm tej yam kev mob.
4. Cov Ntsiab Cai Xaiv Cov Ntsiab Cai ntawm Titanium Alloy Screws
1. Mechanical Performance matching: Xaiv cov ntaub ntawv titanium alloy nrog cov qib sib luag raws li cov khoom siv ceev ceev kom ua tau raws li tensile, shear thiab compressive mechanical indicators.
