Qhuav dej khov thiab thermal txauyog cov txheej txheem tshuaj tsuag uas tau siv dav hauv ntau qhov chaw lag luam. Txawm hais tias lawv ob leeg koom nrog cov tshuaj pleev xim rau ntawm qhov chaw, muaj qee qhov sib txawv ntawm cov hauv paus ntsiab lus, kev siv, thiab cov teebmeem ntawm cov dej khov qhuav qhuav thiab thermal txau. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov sib txawv ntawm qhuav ice spraying thiab thermal spraying.
Ua ntej, cia peb kawm txog cov dej khov qhuav qhuav. Kev txau dej khov qhuav yog ib qho txheej txheem uas siv cov dej khov qhuav kom nrawm nrawm nrawm thiab txau rau ntawm qhov chaw coated. Cov dej khov qhuav yog cov khoom carbon dioxide, yog li nws nkag mus rau sublimation thaum lub sijhawmpleev ximtxheej txheem, ncaj qha transforming ntawm ib lub xeev ruaj khov rau agasxeev tsis ua kua. Cov txheej txheem tshwj xeeb no muab cov dej khov qhuav txau kom zoo hauv ntau daim ntawv thov.
Ib qho tseem ceeb feature ntawm cov dej khov qhuav yog tias nws tsis corrosive. Cov dej khov qhuav yuav ncaj qha hloov mus rau hauv cov pa thaum lub sij hawm txau, tsis muaj qhov seem ntawm qhov chaw. Qhov no ua rau cov dej khov qhuav txau yog qhov kev xaiv zoo tshaj plaws rau kev tu qhov chaw, tshwj xeeb tshaj yog thaum nws los txog rau cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob. Tsis tas li ntawd, vim tias cov dej khov qhuav qhuav tsis tas yuav tsum tau siv cov kuab tshuaj los yog cov tshuaj ntxuav, nws kuj yog ib txoj hauv kev zoo rau kev txau.
Cov dej khov qhuav qhuav kuj muaj cov yam ntxwv ntawm qhov kub thiab txias. Thaum lub sij hawm txau cov txheej txheem, cov dej khov qhuav qhuav nqus cua sov thiab txo qhov kub thiab txias. Qhov no ua rau cov dej khov qhuav qhuav muaj txiaj ntsig zoo hauv qee yam kev siv tshwj xeeb, xws li kev ua zaub mov khov, kev lag luam tshuaj, thiab kev lag luam aerospace. Los ntawm kev tswj lub sijhawm thiab ceev ntawm cov dej khov qhuav qhuav, qhov sib txawv ntawm cov cua txias tuaj yeem ua tiav.
Piv rauqhuav dej khov, thermal spraying yog ib qho kev siv tshuab uas txau cov ntaub ntawv melted los yog ib nrab yaj mus rau qhov coated nto ntawm kev kub ceev. Txoj kev txau no feem ntau siv cov khoom siv hluav taws xob xws li nplaim taws, ntshav arcs, lossis cov kab hluav taws xob los ua kom sov thiab yaj cov ntaub ntawv. Lub ntsiab feature ntawm thermal spraying yog hais tias nws muaj peev xwm tsim ib tug ruaj khov thiab check txheej tiv thaiv ntawm lub nto, thiab muab zoo heev hnav tsis kam, corrosion kuj, thiab kub kuj.
Muaj ntau hom thermal txau cov txheej txheem, suav nrog cov nplaim hluav taws xob, tshuaj tsuag plasma, thiab arc txau. Cov nplaim hluav taws kub hnyiab yog hom ntau tshaj plaws, uas siv cov nplaim hluav taws kub hnyiab cov ntaub ntawv, yaj lawv, thiab tshuaj tsuag rau saum npoo coated. Plasma spraying siv lub plasma arc los ua kom sov cov khoom txheej, thiab qhov kub siab uas tsim los ntawm arc melts nws thiab txau rau saum npoo. Cov txheej txheem thermal txau no feem ntau yuav tsum tau siv rab phom ntxiv los yog cov khoom siv hluav taws xob txau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm thermal txau yog nws cov txheej txheem muaj zog adhesion. Cov khoom siv melted txheej sai sai ua ke nrog lub ntsej muag thaum lub sij hawm txau thiab tsim cov qauv khoom. Qhov no zoo heev adhesion ua rau thermal spraying dav siv nyob rau hauv daim ntaub ntawv uas yuav tsum tau hnav tsis kam, corrosion kuj, los yog kub tsis kam, xws li aerospace, zog, tsheb, thiab manufacturing industries.
Tsis tas li ntawd, thermal spraying kuj tuaj yeem muab ntau yam kev xaiv cov khoom siv sib txawv. Raws li qhov yuav tsum tau ua ntawm daim ntawv thov, ntau hom khoom siv xws li hlau, ceramics, polymers, thiab lwm yam tuaj yeem xaiv rau kev txau. Qhov kev sib txawv no ua rau thermal spraying haum rau ntau yam kev tiv thaiv saum npoo thiab kev ua haujlwm zoo li kev xav tau.
Txawm li cas los xij, piv rauqhuav ice spraying, thermal txaukuj muaj qee qhov kev txwv thiab qhov tsis txaus. Ua ntej, cov txheej txheem thermal txau yuav tsum muaj qhov kub thiab txias thiab lub zog tawm tswv yim, uas tuaj yeem ua rau muaj kev nthuav dav ntawm cov cua sov cuam tshuam rau ntawm qhov chaw coated. Qee zaum, qhov no yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm thiab cov qauv ntawm cov substrate.
Tsis tas li ntawd, cov tshuaj tsuag ceev ntawm thermal spraying kuj qeeb. Vim tias qhov xav tau cua sov thiab melting ntawm cov ntaub ntawv txheej, nrog rau kev ua kom zoo adhesion, cov tshuaj tsuag ceev ntawm thermal spraying feem ntau qis dua. Qhov no tej zaum yuav yog qhov tsis zoo rau cov ntawv thov uas xav tau kev tsim khoom zoo thiab txheej txheej ceev.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb hauv cov hauv paus ntsiab lus thiab kev siv ntawm cov dej khov qhuav qhuav thiab thermal txau. Lub tshuab ziab khaub ncaws qhuav yog qhov tsis muaj corrosive, tsis tshua muaj cua kub txau tshuab uas tuaj yeem ntxuav cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab ua lub luag haujlwm hauv kev ua zaub mov khov, kev lag luam tshuaj, thiab lwm yam. Nws qhov zoo yog nyob rau hauv qhov tsis muaj residues, ib puag ncig tus phooj ywg, thiab cov yam ntxwv ntawm qhov kub thiab txias.
Nyob rau hauv sib piv, thermal spraying yog ib tug txheej txheem txau uas siv high-temperature melting ntawm cov ntaub ntawv txheej los ua ib tug ruaj khov thiab check txheej. Nws muab kev hnav zoo heev, tiv thaiv corrosion, thiab kub tsis kam, haum rau thaj chaw xws li aerospace, lub zog, thiab kev tsim khoom.
Txawm li cas los xij, qhov tsis zoo ntawm thermal spraying yog tias cov teebmeem thermal tsim thaum lub sij hawm txau yuav muaj kev cuam tshuam tsis zoo rau lub substrate, thiab cov tshuaj tsuag nrawm kuj qeeb. Ntawm qhov tod tes, cov dej khov qhuav qhuav tsis muaj qhov cuam tshuam thermal thiab kev txau nrawm nrawm.
Yuav kom suav tau, ob qho tib si qhuav dej khov thiab cov tshuaj tsuag cua sov yog cov txheej txheem tseem ceeb ntawm kev txau uas ua haujlwm sib txawv hauv ntau qhov chaw.Qhuav dej khovyog tsim rau cov ntawv thov uas yuav tsum tau muaj qhov seem ntawm qhov chaw siab, tsis muaj qhov kub thiab txias, thiab kev tiv thaiv ib puag ncig, thaum thermal txau yog tsim rau cov teb uas yuav tsum tau hnav tsis kam, corrosion resistance, thiab high-temperature kev ua tau zoo.
Txawm hais tias xaiv cov dej khov qhuav qhuav los yog txau cov cua sov, kev txiav txim siab yuav tsum tau ua raws li kev thov tshwj xeeb, cov yam ntxwv ntawm cov khoom siv, thiab cov txiaj ntsig xav tau. Kev txhim kho thiab siv cov cuab yeej tshuaj tsuag no yuav ua rau muaj kev vam meej thiab kev tsim kho tshiab hauv ntau yam lag luam.
