Cov khoom no yog dav siv nyob rau hauv kev lag luam ntim, tshwj xeeb tshaj yog rau kev tsim cov khoom noj thiab dej haus. Cov khoom thaiv ntawm aluminium pab tiv thaiv cov ntsiab lus ntawm lub teeb, noo noo, thiab oxygen, ua kom cov khoom tshiab thiab ua kom lub neej ntev. Nws kuj tseem siv tau rau lwm cov ntawv ntim khoom xws li ntawv ci, hau, thiab kaw.
Cov no tsuas yog qee qhov piv txwv ntawm ntau hom kev lag luam thiab cov ntawv thov uas nws tau siv dav. Nws lub teeb yuag, kev siv khoom thaiv, kev ua kom sov, thiab cov khoom siv hluav taws xob ua rau nws cov khoom siv tau yooj yim nrog kev siv deb thiab dav hauv ntau qhov chaw.
Brazing yog ib qho txheej txheem siv los koom nrog nws cov ntu lossis kho qhov chaw puas. Nws muaj txoj hauv kev txhim khu kev qha thiab muaj txiaj ntsig los tsim kev sib raug zoo ntawm lawv. Hauv tsab xov xwm no, peb yuav tham txog cov txheej txheem ntawm brazing cov khoom no thiab cov kauj ruam tsim nyog koom nrog.
Ua ntej brazing, nws yog ib qho tseem ceeb rau kev teeb tsa txheej txheej ntawm aluminium curl los ntawm kev tshem tawm cov av, oxides, los yog cov khoom txawv teb chaws uas tuaj yeem cuam tshuam rau kev tuav tswj. ruaj khov. Cov txheej txheem tu tshuab xws li xuab zeb lossis hlau txhuam tuaj yeem ua haujlwm, lossis siv cov tshuaj ntxuav kom tsim nyog los tshem tawm cov kab mob tsis zoo.
Flux yog ib qho tseem ceeb ntawm cov txheej txheem brazing vim nws pab tiv thaiv oxidation thaum cua sov. Nws chemically reacts nrog oxide txheej ntawm aluminium nto, tso cai rau kom zoo adhesion ntawm qhov chaw koom. Lub flux kuj tseem pab txhawb kev khiav ntawm cov khoom muab tub lim rau hauv qhov sib koom ua ke. Muaj ntau yam kev hloov pauv tau siv tau, suav nrog kev puas tsuaj thiab tsis muaj kev puas tsuaj, cuam tshuam raws li kev thov tshwj xeeb.
Nws brazing feem ntau yog ua los ntawm kev siv lub teeb los yog qhov cub. Lub tshav kub yog siv rau thaj tsam sib koom ua ke kom txog thaum lub hauv paus hlau ncav cuag qhov ntsuas kub kom haum rau cov khoom muab tub lim kom yaj. Nws yog ib qho tseem ceeb kom sov lub txhuas tusyees kom tsis txhob thermal stress los yog distortion. Thaum lub hauv paus hlau ncav cuag qhov xav tau ntawm qhov kub thiab txias, cov khoom molten muab tub lim, feem ntau yog nyob rau hauv daim ntawv ntawm ib tug hlau los yog pre-ntim ntawv ci, yog nkag mus rau hauv kev sib koom ua ke. Cov khoom siv muab tub lim yuav tsum muaj qhov qis qis dua li cov txhuas kom ntseeg tau tias nws ntws thiab kev sib raug zoo.
Tom qab cov txheej txheem brazing, nws yog ib qho tseem ceeb kom txias cov khoom maj mam los tiv thaiv thermal kev nyuaj siab thiab tswj kev ncaj ncees ntawm kev sib koom tes. Kev txias nrawm tuaj yeem ua rau tawg lossis tawg. Thaum lub rooj sib dhos brazed tau txias, cov dej ntau dhau lossis cov seem yuav tsum tau muab tshem tawm. Flux residues tuaj yeem raug ntxuav los ntawm cov txheej txheem tsim nyog, xws li txhuam los yog ntxuav nrog dej los yog tus neeg saib xyuas tshwj xeeb rau hom flux siv. Nws yog ib qho tseem ceeb kom tshem tawm tag nrho cov residues vim tias lawv tuaj yeem cuam tshuam cov tsos thiab kev ua haujlwm ntawm kev sib koom ua ke.
Tsis tas li ntawd, nyob ntawm daim ntawv thov yuav tsum tau, thaj tsam brazed yuav xav tau kev kho saum npoo ntxiv. Qhov no tuaj yeem suav nrog cov txheej txheem kev ua tiav xws li kev sib tsoo lossis polishing los txhim kho cov tsos lossis kev ua haujlwm ntawm kev sib koom ua ke. Anodizing lossis txheej txheej txheej kuj tseem tuaj yeem siv los txhim kho corrosion los yog muab kev tiv thaiv ntxiv.
Hauv kev xaus, brazing yog cov txheej txheem dav siv los koom nrog nws ntu lossis kho qhov chaw puas. Cov txheej txheem suav nrog kev npaj qhov chaw, thov cov flux, cua sov thiab koom nrog cov khoom, thiab ua cov kev kho mob tom qab brazing. Kev npaj kom zoo, kev xaiv flux, cov cua sov sib xws, thiab cov cua txias uas tsim nyog yog qhov tseem ceeb rau kev ua tiav cov pob qij txha zoo hauv nws daim ntawv thov.
Lub ntsuas ntawm nws cov Tshuag hais txog lub thickness ntawm cov ntawv txhuas siv los tsim cov kauj. Nws yog ib qho tseem ceeb xav thaum xaiv cov khoom haum rau ib qho kev thov tshwj xeeb. Aluminium curl Tshuag yog nkag tau rau hauv cov tshev sib txawv, mus los ntawm me ntsis mus rau tuab, thiab qhov kev txiav txim siab yog nyob ntawm qhov tsim nyog ntawm daim ntawv thov.
Qhov ntsuas ntawm cov khoom muaj qhov cuam tshuam ncaj qha rau nws lub zog, durability, thiab yooj. Thicker gauges feem ntau muab lub zog ntau dua thiab nruj, ua rau lawv haum rau cov ntawv thov uas xav tau kev ua haujlwm ruaj khov thiab muaj peev xwm thauj khoom. Kev tsim kho, tsheb, thiab kev lag luam aerospace tag nrho tso siab rau cov ntsuas tuab no rau lawv lub zog thiab kav ntev.
Ntawm qhov tod tes, thinner gauges muab cov formability thiab yooj yim ntawm manipulation. Lawv tuaj yeem khoov, zoo li, thiab tsim rau hauv cov qauv tsim los yog nruj nkhaus yam tsis muaj kev tawg lossis tawg. Cov ntsuas nyias feem ntau nyiam nyob rau hauv cov ntawv thov uas qhov zoo nkauj zoo nkauj yog qhov tseem ceeb, xws li cov phiaj xwm vaj tsev, tsim sab hauv, lossis kos npe. Lawv kuj feem ntau siv rau hauv kev tsim cov txheej txheem uas koom nrog stamping, dabtsi yog khoov, lossis kos duab sib sib zog nqus.
Thaum txiav txim siab qhov kev ntsuam xyuas haum rau ib daim ntawv thov, ob peb lub ntsiab lus yuav tsum xav txog. Cov kev xav tau ntawm cov kabmob ntawm daim ntawv thov ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ntsuas pom zoo. Cov ntawv thov uas muaj cov khoom hnyav lossis xav tau kev txhawb nqa cov qauv feem ntau xav tau cov ntsuas tuab kom ntseeg tau tias tsim nyog lub zog thiab ruaj khov.
Cov xwm txheej ib puag ncig kuj tseem ua lub luag haujlwm hauv kev ntsuas ntsuas. Piv txwv li, cov ntawv thov raug corrosive ib puag ncig lossis huab cua huab cua huab cua yuav tau txais txiaj ntsig los ntawm cov ntsuas tuab nrog kev txhim kho corrosion kuj.
Tsis tas li ntawd, qhov xav tau kev zoo nkauj ntawm cov khoom kawg yog lwm qhov kev xav. Kev ntsuas ntau dua yog ntau zaus xaiv rau cov ntawv thov uas xav tau txoj kev npaj du thiab sib sib zog nqus, thaum cov tshev tuab yuav raug xaiv rau cov ntawv thov uas nyiam qhov muaj zog dua thiab tseem ceeb dua.
