1.What yog qhov cuam tshuam ntawm cov txheej txheej ntawm cov khoom puas ntawm cov hlau galvanized?
Txheej txheej hnyav yog tsawg dhau (piv txwv li, hauv qab no z40): Cov khaub ncaws zinc dhau heev (piv txwv li kev sib tw sib npaug Yog hais tias tus khoov kaum sab xis yog loj (piv txwv li, 180℃lub kaus mom yuav yog "Torn
Txheej txheej hnyav dhau (piv txwv li, saum toj no Z180): Lub zinc txheej ntawm lub zensile (piv txwv li cov txheej txheem zinc Qhov no tuaj yeem ua rau tawg, wrinkling, lossis flaking ntawm cov txheej vim "tsis muaj zinc tsis yooj yim," tshwj xeeb tshaj yog nyob rau ntawm me me radii. Piv txwv li, qhov tshwm sim ntawm zinc tawg hauv z275 tuab - Coated steel thaum bent ntawm ib tug me me 90 solitly voj voog yog qhov siab dua uas muaj z100-coated steel. Haum ntau yam: Cov txheej txheem dabtsi yog khoov (xws li kev txhim kho tsev thiab cov khoom siv hauv tsev) yog cov khoom siv z60 z120 ntau. Cov txheej zinc txheej muaj ib qho thickness, uas tuaj yeem ua tau raws li kev ua kom muaj kev sib koom tes deformation thaum tsis tau nyias nyias kom ua rau hauv qab.
2.What yog qhov cuam tshuam rau kev ua yeeb yam?
Txheej txheej hnyav thiab kev sib txhuam sib txhuam: "sprantic txheej (piv txwv li} Cov txheej txheej tuab (piv txwv li, z150 thiab siab dua) tsis muaj cov kab du yuav muaj cov kab mob sib tw thiab cov plaub hau. Qhov no nce cov kev txhuam tawm tsam nrog kev tuag thaum lub sijhawm kaw, ua rau nws muaj kev sib txhuam tsis zoo, lossis tsis muaj peev xwm sib txhuam thiab cov khoom siv tsis sib xws thiab wrinkling) ntawm workpiece.
Hloov pauv, nyias nyias (piv txwv li, z60 {{4 4} {{{{10} {{{10} {{ (Rau tob-kos-kos cov hlau galvanized zoo li DX53D + Z, kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv kab ke.) Kev muaj kev ntxhov siab thiab kev ntxhov siab tensile los ntawm pwm. Yog tias cov nplaum ntawm cov txheej tuab yog tsis txaus (piv txwv li, ib qho oxide txheej uas muaj tshwm sim ntawm cov fillets thiab thaj chaw nrog cov khoom lag luam loj dua). Qhov no tuaj yeem pom tias yog nplaim taws "bubbling" lossis zinc txheej flakes poob tawm, uas tsis yog ua rau txo qis dua hauv txheej nplaum (xws li cov xim pleev tshuaj).
3.Qhov dab tsi cuam tshuam rau kev siv cov txheej txheem vuam?
Ntau txheej txheej hnyav: tuab zinc txheej → ntau dhau zinc vapor evaporates thaum vuam. Yog tias cov vapor no tsis tuaj yeem khiav tawm sai sai, nws tuaj yeem yooj yim tsim cov hws thiab cov nplais me me hauv Weld (tshwj xeeb hauv cov vuam, qhov chaw zinc vuam tuaj yeem cuam tshuam nrog Arc stability). Ntau dhau zinc vapor kuj tseem tuaj yeem ua rau cov neeg pluag weld fusion lossis tsim ntawm "zinc britive txheej" ze rau ntawm weld (zinc reacts), txo weld lub zog), txo weld lub zog), txo weld lub zog.
Piv txwv li, thaum vuam z180-coated steel, qhov xwm txheej ntawm pores yog tshaj 30% siab dua li ntawm z80-coated steel. Qhov no yuav tsum tau tswj ntxiv ntawm vuam tam sim no thiab nrawm (piv txwv li, nce ntxiv tam sim no kom nrawm zinc vapor khiav dim), nce cov txheej txheem nyuaj.
Leev txheej hnyav: nyias zinc txheej → Txawm li cas los xij, kev saib xyuas yuav tsum tau them rau kev tiv thaiv cov cua sov -} cuam tshuam thaj chaw (Haz). Ib txheej zinc nyias tuaj yeem oxidize ntawm siab vuam kub, ua rau cov xeb tsis txaus ntseeg (re {} {}} xeb pleev xim yog qhov tsim nyog).
4.Qhov dab tsi cuam tshuam rau ntawm shearing / txiav kev ua tau zoo?
Ntau dua txheej hnyav: cov txheej zinc yog tuab thiab muaj nkig. Thaum lub sij hawm shearing, zinc txheej ntawm cov npoo tau yooj yim tawg thiab cais tawm vim yog "shear cuam tshuam, xav tau kev kho mob ntxiv (xws li kev kho mob hla) kom tiv thaiv xeb. Yog tias txiav laser yog siv, cov txheej tuab zinc yuav ua rau muaj ntau npaum li cas ntawm zinc slag, uas ua raws li cov nqi huv.
Kev txiav ntau dhau ntawm cov txheej hnyav: cov txheej zinc yog nyias thiab muaj ntau dua nruj nreem rau lub substrate. Cov txheej zinc txheej yog qhov tsawg dua yuav txhawm rau hauv cov npoo thaum lub sij hawm shearing, uas ua rau txiav cov npoo av, yooj yim ntxiv.
5. Dab tsi yog tus "tseem ceeb ua rau muaj logic" ntawm cov txheej txheej ntawm kev ua haujlwm?
Tsawg txheej hnyav (z40-z80): Haum rau cov txheej txheem xws li kev tsim kho, tab sis yuav tsum muaj kev tiv thaiv me me ntawm cov txheej zinc nyias nyias.
Nruab nrab txheej hnyav (Z80-Z120): Muaj cov kev ua tau zoo tshaj plaws thiab tsim nyog rau kev siv thoob plaws hauv kev siv tsheb, kev siv hluav taws xob, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab kev tsim kho hauv tsev, thiab siv tsev.
High txheej hnyav (Z150 thiab siab dua): Pom zoo tsuas yog rau cov kev siv uas yuav tsum tau ua kom muaj kev tawm tsam tshiab (xws li sab nraum zoov billboards thiab zoo li qub nkhaus). Cov stamping nyuaj thiab me me- lub log radius} lub log radioms yuav tsum tau zam, thiab vuam siv cov tshuaj tshwj xeeb.
