1.Vim li cas galvanized coils haum rau ntug-jointing?
Formability zoo heev:
Lub substrate ntawm galvanized coils feem ntau yog qis - carbon steel, muaj qhov yooj yooj yim thiab ductility. Qhov no tso cai rau nws mus txuas ntxiv dov mus rau ntau yam kev sib txawv ntawm ntug (xws li ntsug seams, kab rov tav seams, thiab lwm yam) los ntawm cov cav tov yam tsis muaj kev tawg.
Inherent Corrosion Protection:
Zinc txheej muab kev tiv thaiv kev txi rau cov hlau substrate. Txawm hais tias cov txheej txheem raug khawb me me los yog deformation thaum lub sij hawm dov, zinc nyiam dua corrodes, tiv thaiv cov hlau sab hauv thiab tiv thaiv xeb los ntawm kev sib koom ua ke. Qhov no yog ib qho tseem ceeb rau lub sij hawm ntev - durability.
Smooth Surface thiab High Consistency:
Lub npoo du ntawm galvanized coils ua kom yooj yim rau siab -ceev, meej yob tsim ntawm cov kab ntau lawm, kom ntseeg tau qhov ntev ntawm txhua qhov txuas.
2.Yuav ua li cas hom dov ntug sib txuas muaj?
Vertical seam kev twb kev txuas: Feem ntau siv nyob rau hauv hlau vov tsev systems. Ob lub vaj huam sib luag tau koom ua ke ntawm lawv cov npoo ncaj thiab tom qab ntawd muab khi nrog cov seam tshwj xeeb - lub tshuab kaw. Txoj kev sib txuas no ua tau zoo tiv thaiv dej nag thiab tuaj yeem ua kom haum rau thermal expansion thiab contraction.
Smooth seam kev twb kev txuas: Feem ntau siv nyob rau hauv qhov cua ducts thiab phab ntsa panels. Cov npoo ntawm cov vaj huam sib luag yog bent, hooked ua ke, thiab nias nruj nreem kom tsim ib tug seam du.
Locked seam kev twb kev txuas: Lwm txoj kev sib txuas ntawm cov khoom siv feem ntau siv hauv cov kav dej, suav nrog ib qho -lock thiab ua ke kaum -lock hom.
3.Yuav ua li cas xaiv lub thickness thiab hom zinc txheej?
Zinc Txheej Nyhav: Rau kev siv sab nraum zoov lossis qhov chaw corrosive, cov zinc txheej tuab (xws li Z275 tsis yog Z180) yuav tsum tau muab lub neej ntev dua.
Kev Kho Hniav: Tus qauv passivation (chromium-dawb lossis trivalent chromium) feem ntau tiv thaiv cov xeb dawb thiab muaj kev cuam tshuam me ntsis ntawm kev ua tiav ntawm ntug. Txawm li cas los xij, yog tias yuav tsum tau pleev xim tom qab, yuav tsum xaiv tus ntiv tes -resistant, roj-resistant, los yog tshwj xeeb kho nto yuav tsum tau xaiv.
4.Dab tsi yuav tsum tau ceev faj txog kev tsim khoom thiab kev siv tiag tiag?
Lubrication:
Thaum lub sij hawm siab - yob txoj kev ceev, lubrication kom zoo txo pwm hnav, tiv thaiv zinc txheej tev los yog khawb, thiab ua kom zoo zoo crimp zoo. Ib lub teeb daim ntawv thov roj rau cov khoom nto yog feem ntau txaus.
Tool thiab Pwm Hnav:
Zinc yog softer dua hlau, tab sis ntev nruam ntau lawm yuav ua rau ib co coj mus ua pwm. Pwm ua los ntawm hnav- cov ntaub ntawv tiv taus yuav tsum tau, nrog rau kev saib xyuas tsis tu ncua.
Cov cuab yeej ua haujlwm tshwj xeeb:
Crimp koom feem ntau yuav tsum tau tshwj xeeb yob txoj kev tshuab thiab overlock tshuab kom ua tau siab -zoo, siab- efficiency ntau lawm. Cov cuab yeej tes tsuas yog tsim rau me me - nplai lossis kho daim ntawv thov.
5.Dab tsi yog qee qhov kev thov raug cai?
Hlau ntsug sib koom ua ke vov tsev: Qhov no yog daim ntawv thov classic tshaj plaws ntawm galvanized dov ntug kev sib txuas. Nws muab cov nag thiab cua tiv taus zoo heev.
Qhov cua thiab cua txias ducts: Galvanized steel ntawv ducts feem ntau siv dov ntug (interlocking) kev sib txuas kom ntseeg tau tias airtightness thiab lub zog.
Phab ntsa vaj huam sib luag: Qee cov phab ntsa vaj huam sib luag kuj tseem siv cov kev sib txuas ntawm cov npoo npog, uas ua rau kom huv thiab zoo nkauj zoo nkauj.
