Kev txhim kho tas mus li ntawm lub tshuab nqus tsev txheej tshuab, kom ntau yam ntawm cov khoom qub tsis tuaj yeem coated, tab sis tseem muaj qee cov ntaub ntawv tseem tsis tau tsim cov kev daws teeb meem, tab sis kuv tab tom nrhiav rau pem hauv ntej, vim tias kev siv tshuab tsis muaj qhov kawg. , ntau yam ntawm yav dhau los twv tsis xav txog cov cuab yeej technology, tam sim no paub, lub neej yav tom ntej yuav tsum tshwm sim ib nplooj ntawv tshiab.
Rau lub tshuab nqus tsev txheej tshuab, yas kuj tuaj yeem coated, uas yog ib qho kev txhim kho, tab sis tsis yog tag nrho cov yas tuaj yeem coated nrog lub tshuab nqus tsev, vim tias cov yas nws tus kheej nrog qee yam ntawm cov txheej txheem txheej txheem tam sim no tseem tsis tau daws.
Yog li dab tsi ntawm cov yas tuaj yeem coated los ntawm lub tshuab nqus tsev?
Ua ntej ntawm tag nrho cov, yuav tsum muaj ib tug tej yam affinity ntawm cov yas nws tus kheej thiab txheej txheej, tsuas yog cov zaj duab xis txheej thiab lub workpiece nyob ze ua ke, thiaj li tsis yooj yim rau poob tawm, lub neej ntev, ib co yas yuav tsis tau zoo ua ke nrog. txheej wax, cov kws tshawb fawb pom tias cov yas saum npoo ua ntej coated nrog ib txheej ntawm cov xim los pab txhawb kev sib xyaw ua ke ntawm cov zaj duab xis txheej, thiaj li daws tau qhov teeb meem ntawm adhesion, tab sis cov txheej no tuaj yeem ntxiv dag zog rau kev sib xyaw ua ke nrog cov yeeb yaj kiab.
txheej sab nraud, tam sim no kuj txhawm rau ntxiv dag zog rau daim ntawv cog lus nrog cov yas, thiab tib lub sijhawm kom ua tau raws li ob qho xwm txheej ntawm txheej txheej tsis yog qhov yooj yim mus nrhiav, tsuas yog ib feem ntawm cov yas tuaj yeem pom cov txheej txheem sib xws, tab sis qee qhov ntawm cov yas yog ib txwm tseem tsis tau pom, thiab cov yas no tsis tuaj yeem raug coated nrog lub tshuab nqus tsev.
Qhov thib ob, cov yas nws tus kheej yuav yeej muaj qee qhov tsis haum tshuaj, nrog rau qhov kub thiab txias, yuav tsis hloov pauv, tab sis raws li cov khoom siv tuaj yeem coated, cov khoom tsis muaj zog tuaj yeem zam tau raug txwv, yog li hauv kev xaiv cov ntaub ntawv yas rau lub tshuab nqus tsev, xaiv qhov tsawg dua outgassing, yog li rau lub tshuab nqus tsev txheej tshuab ua haujlwm ntawm lub tshuab nqus tsev kawm ntawv ntawm qhov cuam tshuam kuj tuaj yeem siv cov kev ntsuas los ua kom nws tswj tau, yog tias muaj ntau cov lus yuav tsis raug tswj thiab lub tshuab nqus tsev yuav raug txo thiab cov txheej txheem zoo. yuav raug cuam tshuam.
Qhov kawg yog qhov ruaj khov ntawm cov cua sov yas, cov yas siv dav siv yog vim nws tuaj yeem nyob rau hauv lub xeev ntawm cov cua sov raws li tus tsim qauv xav kom cov duab xav tau, uas yog kub deformation, tab sis nyob rau hauv lub tshuab nqus tsev txheej tshuab txheej ib puag ncig, yuav tsum. tsim kom muaj qhov kub thiab txias, yog tias cov yas tsis ruaj khov, nws yuav yog qhov zoo.
Yog tias cov yas tsis ruaj khov los ntawm cov cua sov, nws yuav deformed, txawm tias txheej txheej zoo, cov khoom ua haujlwm tau deformed, thiab siv nws li cas, yog li rau txheej txheej ntawm cov ntaub ntawv yas, yuav siv lub tshuab nqus tsev. uas generates tshav kub hauv qab lub melting point ntawm workpiece, tab sis ib co yas melting point yog tiag tiag tsawg, tam sim no technology tsis tau daws, yog li cov yas no tsis haum rau lub tshuab nqus tsev txheej tshuab txheej.
