Peb Qhov Zoo
1. Oxidation thiab kub tsis kam
- Titanium yeeb nkab rau lub tshuab tso pa tawm yog tsim los ntawm tus qauv - cov ntaub ntawv ua raws thiab tau txais kev tshuaj xyuas spectrometer thiab kuaj. Cov impurities xws li oxygen, nitrogen, hydrogen, thiab hlau yog nruj me ntsis tswj kom cov yeeb nkab tswj kev ruaj ntseg ntawm qhov kub thiab txias.
- Peb cov kav dej tau dhau los ua cov txheej txheem kho cua sov kom txhim kho lawv qhov kev nkag siab ntawm qhov kub thiab txias, thiab lawv tau dhau qhov kev ntsuas kub ntawm - qhov kub thiab txias, kom tsis txhob deformation lossis oxidation tev tawm txawm tias tom qab ntev - lub sij hawm raug rau 400-700℃.
2. Corrosion Resistance
- Cov khoom siv hauv tsheb feem ntau cuam tshuam rau cov dej noo, ntsev, siab - cua kub gases, thiab acidic condensates. Titanium cov kav dej ib txwm tsim cov yeeb yaj kiab oxide, tiv thaiv corrosion los ntawm cov tshuaj no thiab ua kom cov yeeb nkab ntev ntev.
- Cov kav dej tau raug kuaj xyuas nruj heev, suav nrog kev ntsuas tshuaj ntsev thiab tshuaj ntsuam xyuas acidic condensate corrosion, kom ntseeg tau tias lawv ua haujlwm tau zoo hauv cov tshuab hluav taws xob hauv tsheb.
3. Lub teeb yuag thiab siab -Lub zog
- Titanium muaj qhov ceev ntawm kwv yees li 4.5 g / cm³, ua rau nws li 40-50% sib dua li cov hlau tsis muaj steel. Qhov no txo qhov hnyav tag nrho ntawm cov yeeb nkab tso pa, ua kom lub tsheb nrawm dua, tuav, thiab roj efficiency.
- Cov yeeb nkab tau kuaj xyuas cov cuab yeej cuab tam kom ntseeg tau tias nws lub zog tensile, lub zog tawm los, thiab lwm yam khoom raws li ASTM B861 cov qauv.
4. Kev kho deg
- Titanium yeeb nkab rau cov pa tawm yog pickled, polished, thiab ci ntsa iab annealed kom ua tiav ib qho chaw zoo nkauj uas txhim kho kev zoo nkauj thiab kev tiv thaiv corrosion.
- Cov kav dej tau raug kuaj xyuas zoo, nrog rau qhov chaw roughness Ra tsawg dua lossis sib npaug li 1.6μm, passivation zaj duab xis thickness ntawm 5-10μm, thiab qhov chaw tsis muaj khawb, pitting, thiab lwm yam tsis xws luag.
5. Kev ua haujlwm sealing
- Lub sealing kev ua tau zoo ntawm automotive tso yeeb nkab ncaj qha cuam tshuam rau lub cav fais fab tso zis. Peb cov kav dej tso tawm yog tsim los siv cov txheej txheem txias - kos duab, kom ntseeg tau tias qhov ntev thiab tsis muaj qhov khoob lossis qhov tsis muaj zog, tso cai rau kom haum zoo nrog lub tsheb lub tso pa tawm.
- Titanium muaj kev ruaj ntseg zoo heev, uas ua rau nws tswj tau cov khoom siv kho tshuab zoo nyob rau hauv qhov kub thiab txias hauv cov cua txias, tsis muaj deforming vim cua sov, yog li txo qhov kev pheej hmoo ntawm to.
thaj chaw thov
- Automotive Exhaust Systems: Headers thiab downpipes, nruab nrab -pipes thiab tailpipes, turbocharger tso tshuab, thiab lwm yam.
- Motorcycle Exhaust Systems: Kev cai sib tw cov kav dej, plam- ntawm mufflers, thiab txuas, thiab lwm yam.
