Qhov sib txawv ntawm GI thiab MS
Muaj ob qho txuj ci uas yuav siv los ua cov hlau galvanized. Qhov feem ntau yog kub-dip galvanization, nyob rau hauv uas cov hlau tau tsiv los ntawm qhov kub tsis tshua muaj kub ntawm molten zinc, uas tuaj yeem sib xyaw nrog cov hmoov txhuas me me, nyob ntawm seb muaj xwm txheej. Thaum cov hlau tawm hauv da dej, cov zinc yuav muaj kev sib koom tes, tsim txheej txheej zinc ntawm nplaim hlau. Qee zaum, cov hlau tuaj yeem dhau los ntawm kev siv zeb los ua kom tiaj thiab txawm tias tawm los ntawm txheej. Lwm cov txheej txheem uas tuaj yeem siv tau yog electrodeposition, tseem hu ua electroplating, txawm hais tias qhov no tsis tshua muaj.Yog li galvanized, hlau npog hauv ib txheej ntawm zinc uas yuav ci ci rau cov xim grey. Cov tshuaj pleev xim zinc tuaj yeem pleev xim, yog tias xav tau, lossis sab laug. Kev pleev xim tha xim feem ntau ua tiav thaum cov hlau yuav tsum sib phim nrog lwm cov khoom siv hauv tsev, lossis thaum tib neeg xav ua kom pom tseeb. Hauv lub vaj, piv txwv li, nws yuav pleev xim ntsuab kom nws yuav sib xyaw rau hauv cov nplooj ntoo es tsis txhob sawv tawm.
Ntev npaum li cov zinc txheej tseem zoo li qub, cov hlau galvanized yuav tsum nyob twj ywm rau qhov xwm txheej zoo. Txawm li cas los xij, cov kab mob acidic tuaj yeem yaig zinc hauv lub sijhawm, tsim kev thaj ua rau xeb qhov twg corrosion tuaj yeem tshwm sim. Kev xeb kuj tseem tuaj yeem tshwm sim thaum txheej txheej nkag mus, zoo li thaum ib tus neeg tsav ntsia hlau los ntawm daim ntawv ntawm cov hlau galvanized, ua kom pom cov hlau hauv sab hauv rau cov khoom. Thaum xeb pib, nws tuaj yeem sib kis tau rau hauv qab zinc, nws thiaj li ua rau cov hlau tsis tas.Yog muaj ntau hom kev siv rau hom hlau, uas tuaj hauv cov kav dej, cov ceg tawv, cov ntawv, thiab cov hlau, thiab lwm hom. Ntau cov khoom siv kho vajtse thiab cov khoom siv hauv tsev nqa cov khoom lag luam galvanized hlau thiab tej zaum yuav txaus siab txiav rau cov khoom siv rau cov kev cai ntau thiab tsawg tau thov. Tib neeg tseem tuaj yeem raug xa mus rau cov kws tshaj lij uas yuav txuas rau lossis txiav cov hlau galvanized kom tau raws li qhov xav tau ntawm ib qhov haujlwm tshwj xeeb.
Cov hlau me yog qhov tsawg tshaj li tus nqi ntawm cov hlau thiab cov feem ntau siv cov hlau. Siv nyob rau hauv yuav luag txhua hom khoom tsim los ntawm cov hlau, nws yog weldable, nyuaj heev thiab, txawm tias nws yooj yim xeb, siv tau ntev heev. Muaj cov siab kawg ntawm 0.29% cov pa roj carbon, hom hlau no tuaj yeem ua kom muaj hlau nplaum thiab siv nyob rau hauv yuav luag txhua qhov haujlwm uas yuav tsum muaj hlau ntau. ntawm cov khoom siv niaj hnub uas tau tsim los ntawm cov hlau tau ua siv cov hlau me, nrog rau lub tsheb chassis, lub cev maus taus, thiab feem ntau cov khoom siv ua noj. Vim nws qhov kev xeb tsis zoo, nws yuav tsum pleev xim lossis tiv thaiv thiab kaw thiab txhawm rau txhawm rau tiv thaiv xeb los ntawm kev ua kom nws. Ib lub tsho tiv no ntawm cov roj lossis cov roj yog muaj peev xwm kaw cov hlau no thiab kev pab hauv kev tswj xeb.
Tsis zoo li high-carbon steel, hlau me yog yooj yim welded. Cov yam ntxwv ntawm cov hlau tso cai rau lub tshuab hluav taws xob hloov mus los los ntawm cov hlau yam tsis cuam tshuam qhov pleev ntawm cov khoom. Qee hom qib siab carbon hlau, xws li steel hlau, yuav tsum muaj cov txuj ci tshwj xeeb kom thiaj li txuas tau cov khoom sib txuas. Raug tsawg dua li cov pa roj carbon ntau ntau, qhov sib txawv me me muaj peev xwm hloov tau thiab muab rau hauv cov phiaj xwm kev tsim ua qhov twg cov pa roj carbon ntau dua tuaj yeem tsoo.
Feem ntau ntawm cov raj dej hauv lub ntiaj teb yog tsim los siv cov hlau tsis khov. Qhov no tso cai rau cov yeeb nkab kom tsis tsuas yog tau yooj yim welded rau hauv qhov chaw, tab sis kuj cia tus kav raj xa dej thiab tsis txhob tawg thiab tawg hauv qab lub siab. Cov cuab yeej tiv thaiv tsis zoo ntawm cov kav hlau txhais tau tias nws yuav tsum tau muab ntim zoo los ntawm kev pleev xim los yog cov txheej txheem feem ntau siv rau ntawm cov raj dej uas yuav tsum tau qhwv cov yeeb nkab nrog cov khoom tiv thaiv corrosive.Often hauv cov huab cua txias heev, hom sov so ntawm insulating yog qhwv ib puag ncig. lub raj xa dej. Cov khoom no pab ua kom txias hauv cov yeeb nkab khiav kom zoo. Cov ntawv qhwv kuj tseem tiv thaiv qhov muag muag hlau yeeb yaj kiab kom tsis txhob ua nkig thiab tawg. Qhov kev nthuav dav tas mus li thiab txo qis vim qhov txias thiab sov caij tsheb kauj vab hauv cov yeeb nkab tuaj yeem tsim cov teeb meem kev teeb tsa, tab sis cov no tau tuav los ntawm daim ntawv insulating. Ntawm qhov ntsuas ntau me me, cov kav dej hauv tsev tuaj yeem tiv thaiv kom tsis txhob txias thiab tawg los ntawm kev siv hluav taws xob cua sov daim kab xev.
