Automotive tso yeeb nkab luj tshib feem ntau yog ua los ntawm titanium. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm titanium tso cai rau nws los tsim cov txheej txheem tiv thaiv ntawm nws qhov chaw, tiv thaiv corrosion thiab tiv thaiv xeb, yog li tswj lub luj tshib hauv kev ua haujlwm zoo. Txawm li cas los xij, cov yam ntxwv ntawm titanium kuj hais tshwj xeeb rau kev tu thiab kev teeb tsa. Kev ua haujlwm tsis zoo tuaj yeem ua tsis tau tsuas yog ua rau lub ntsej muag tiv thaiv kab mob tab sis kuj cuam tshuam rau kev sib khi ua haujlwm thiab kev pabcuam lub neej ntawm lub luj tshib. Yog li ntawd, nws yog ib qho tseem ceeb kom ua raws li cov txheej txheem nruj me ntsis thiab ua tib zoo saib xyuas txhua yam hauv lub sijhawm ua haujlwm tiag tiag.
Thaum ntxuav lub tsheb titanium lub luj tshib, nws yog ib qho tsim nyog yuav tau xaiv cov kev tu kom tsim nyog raws li qhov xav tau ntawm cov khoom ua haujlwm tiag tiag, qib ntawm qhov paug paug, thiab kev puas tsuaj. Cov kev siv feem ntau suav nrog kev ntxuav alkaline, so nrog dej - cov tshuaj ntxuav cov dej soluble, cov tshuaj chlorine hnyav sandblasting, thiab tua blasting. Cov txheej txheem no tuaj yeem tshem tawm cov stains thiab oxide txheej thaum kawg tiv thaiv cov qauv kev tiv thaiv ntawm titanium nto, zam cov khoom puas. Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tias acid pickling yog nruj me ntsis txwv tsis pub thaum lub sij hawm ntxuav. Acid pickling yuav cuam tshuam cov tshuaj sib npaug ntawm cov khoom siv titanium, corrode txheej tiv thaiv nto, thiab txo nws cov xeb thiab corrosion kuj, ua rau muaj teeb meem xeb thiab puas thaum siv tom ntej. Kev tu kom huv thiab zoo tuaj yeem txo qhov kev ua tsis tiav los ntawm cov av nkos thiab cov khoom siv corrosion thaum siv titanium luj tshib, txhim kho kev nyab xeeb tag nrho ntawm cov yeeb nkab tso pa, thiab txuas ntxiv lub neej kev pab cuam ntawm lub luj tshib titanium thiab tag nrho cov pa tawm.
Yog hais tias vuam yuav tsum tau thaum lub sij hawm installation ntawm lub luj tshib titanium, cov ntsiab lus ntawm cov txheej txheem vuam ncaj qha cuam tshuam qhov zoo ntawm lub luj tshib titanium. Kev tuav thiab xaiv cov welding rods yog cov ntsiab lus tseem ceeb. Vuam rods yuav tsum tau qhuav ua ntej siv. Ntau hom vuam rods muaj qhov sib txawv kom qhuav: titanium-calcium type welding rods yuav tsum tau ziab ntawm 150℃rau 1 teev, thaum qis -hydrogen hom vuam rods xav kom qhuav ntawm 200-250℃rau 1 teev. Tsis tas li ntawd, welding rods yuav tsum tsis txhob qhuav ntau zaus, txwv tsis pub, cov txheej txheej flux yuav tawg thiab tev tawm, poob nws txoj haujlwm tiv thaiv. Nyob rau tib lub sijhawm, kev khaws cia kom zoo thiab kev tiv thaiv ntawm cov welding rods yog qhov tseem ceeb los tiv thaiv cov txheej txheem flux kom tsis txhob muaj roj, plua plav, thiab lwm yam av. Yog hais tias cov txheej txheem flux tsis muaj paug, nws yuav ua rau muaj kev nce hauv cov ntsiab lus ntawm cov khoom siv vuam thaum lub sij hawm vuam, cuam tshuam rau lub zog thiab corrosion kuj ntawm vuam, thiab yog li txo qhov zoo ntawm tag nrho cov welded ib feem. Cov yam ntxwv vuam ntawm titanium lub luj tshib txawv ntawm cov hlau zoo tib yam. Thaum lub sij hawm vuam, titanium lub luj tshib raug cuam tshuam los ntawm kev rov ua cua sov, uas yooj yim ua rau carbide nag lossis daus hauv cov khoom.
Qhov no ncaj qha txo cov corrosion kuj thiab txhua yam khoom ntawm titanium luj tshib. Tsis tas li ntawd, cov khoom siv tawv tawv heev tom qab vuam, ua rau nws muaj kev cuam tshuam rau kev tawg thaum lub caij txias, yog li cuam tshuam rau kev nyab xeeb. Txhawm rau daws qhov teeb meem no, txoj kev vuam tsim nyog yuav tsum raug xaiv raws li qhov tseeb: Yog tias siv vuam rods ntawm tib yam khoom titanium raws li lub luj tshib, lub luj tshib titanium yuav tsum tau preheated rau saum 300℃ua ntej vuam, thiab kev kho cua txias ntawm ib ncig ntawm 700℃yuav tsum tau tom qab vuam. Qhov ntsuas kub no txo qis carbide nag lossis daus thiab tiv thaiv kev tawg. Yog tias tom qab-weld kev kho cua sov tsis tuaj yeem ua tsis tau vim qhov chaw teeb tsa lossis kev txwv cov qauv, ces vuam rods ntawm tib hom yuav tsum tau tso tseg, thiab chromium-nickel-titanium vuam rods yuav tsum tau siv los hloov. Cov welding rods muaj kev sib tw vuam zoo dua thiab tuaj yeem ua kom vuam zoo yam tsis muaj kev kho cua sov tom qab, txo qhov kev pheej hmoo ntawm cov kab nrib pleb thiab corrosion.
Tom qab ntxuav thiab vuam lub luj tshib titanium, kev tshuaj xyuas thiab kev npaj ua haujlwm yuav tsum tau ua ua ntej kev teeb tsa raug cai kom tsis txhob muaj teeb meem tshwm sim los ntawm kev tsis saib xyuas ua ntej. Ua ntej, ua tib zoo xyuas tag nrho cov txheej txheem ntawm lub luj tshib titanium kom paub meej tias txoj kab uas hla, qauv, thiab cov ntsiab lus ntawm lub luj tshib titanium zoo kawg nkaus phim cov kev xav tau ntawm cov yeeb nkab tso tawm. Qhov no tiv thaiv cov teeb meem xws li tsis sib haum xeeb, tsis muaj peev xwm txhim kho, lossis kev sib khi tsis zoo tom qab kev teeb tsa. Qhov thib ob, xyuas seb lub luj tshib titanium puas muaj qhov tsis xws luag xws li pob, deformation, lossis khawb thaum thauj thiab khaws cia. Yog tias pom muaj teeb meem, lawv yuav tsum tau kho lossis hloov tam sim ntawd kom tsis txhob cuam tshuam rau kev siv tom ntej. Thaum kawg, ntxuav qhov saum npoo ntawm lub luj tshib titanium dua kom tshem tawm cov av, vuam slag, plua plav, thiab lwm yam khib nyiab, ua kom lub ntsej muag huv thiab huv si rau kev txhim kho du.
Thaum lub sij hawm kev teeb tsa, lub luj tshib titanium tuaj yeem raug ntsia ncaj qha rau ntawm cov kav dej sib txuas raws li nws txoj kev sib txuas. Lub installation txoj hauj lwm yuav tsum tau nruj me ntsis txiav txim siab raws li qhov yuav tsum tau los ua ke ntawm cov pa yeeb nkab kom paub meej lub kaum sab xis thiab txoj hauj lwm ntawm kev sib txuas ntawm lub luj tshib titanium thiab cov kav dej. Lub hauv paus ntawm lub installation yog sealing zoo. Xyuas seb cov gaskets, O-rings, thiab lwm yam khoom siv puas zoo lawm, thiab xyuas kom meej tias lawv tau haum rau lub sealing txoj hauj lwm thaum lub sij hawm installation los xyuas kom meej ib tug nruj thiab seamless kev twb kev txuas thiab tiv thaiv kom txhob tso pa tawm. Yog tias lub foob tsis nruj, nws yuav tsis tsuas yog ua rau lub suab nrov ntawm lub tsheb, tab sis kuj cuam tshuam rau lub cav lub tshuab pa, yog li cuam tshuam rau lub tsheb lub zog kev ua haujlwm thiab kev lag luam roj. Hauv qhov xwm txheej hnyav, cov pa tawm tuaj yeem ua rau muaj kev phom sij.
Zuag qhia tag nrho, kev tu thiab kev teeb tsa ntawm titanium tso cov yeeb nkab khoov hauv lub tsheb koom nrog cov txheej txheem kev khiav hauj lwm tshwj xeeb thiab kev ceev faj ntawm txhua kauj ruam. Tsuas yog los ntawm kev ua raws li cov txheej txheem nruj me ntsis thiab ua tib zoo saib xyuas cov ntsiab lus tuaj yeem ua kom muaj kev txhim kho zoo ntawm titanium khoov, tso cai rau cov khoom siv titanium kom siv tag nrho nws cov kev tiv thaiv corrosion thiab hnav tsis kam, tswj cov titanium khoov hauv kev ua haujlwm zoo, thiab ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm lub tsheb lub tso pa tawm.
