Hais txog qib steel
Tam sim no nws yog qhov feem ntau siv, xws li TDC51 qib uas tsim los ntawm Baosteel, lub zog tawm los ntawm 260-320Mpa, thiab lub zog tensile nyob nruab nrab ntawm 350-400Mpa. Piv nrog rau cov qauv hlau, nws cov txiaj ntsig lub zog piv yog siab dua me ntsis.
txog dav
Kev xa khoom raug ntawm cov hlau coils hauv txhua lub teb chaws hauv ntiaj teb yog qhov ua tau zoo, uas yog, qhov dav dav dav dav dua los yog sib npaug rau qhov dav nominal thaum lub sijhawm xaj. Kev tswj hwm ntawm cov dav dav no feem ntau suav hais tias yog thaum lub phaj steel yog txias-dov, vim tias cov txheej txheem galvanizing thiab xim txheej tom ntej yuav cuam tshuam rau kev tiv thaiv corrosion ntawm ntug yog tias cov txheej txheem trimming ua tiav. Tab sis yog tias qhov zoo siab ntev ntawm cov phaj hlau loj dhau, nws yuav dhau qhov kev txwv pub noj ntawm lub tshuab tsim. Raws li kev paub dhau los, nws yog qhov tsim nyog los tswj nws ntawm 0-5mm.
txog thickness
Lub thickness ntawmPpgi Xim Coated Sheetslos ntawm ntau yam manufacturers muaj ntau lub ntsiab lus.
Lub thickness cim rau ntawm daim ntawv lo ntawm cov xim-coated steel kauj yog qee zaum lub thickness ntawm substrate, ib co yog lub thickness ntawm substrate ntxiv rau lub thickness ntawm txheej, thiab ib co yog lub thickness ntawm lub substrate ntxiv rau lub thickness ntawm txheej ntxiv. lub thickness ntawm txheej.
Baosteel tam sim no tau txais cov txheej txheem substrate ntxiv rau txheej tuab (tsis suav nrog xim txheej). Qhov no txoj kev ntawm thickness xam yog haum rau lub tsev designers, vim hais tias lub zog ntawm cov xim txheej yog tsawg. Xav txog cov qauv tsim thiab kev nyab xeeb Qhov kev sib deev yuav tsum tsis txhob muab rau hauv tus account. Nyob rau hauv tib txoj kev, nyob rau hauv cov nqe lus ntawm tus me nyuam thickness kam rau ua, Baosteel yeej ib txwm ua raws li qhov zoo kam rau ua tus me nyuam. Nyob rau hauv txoj kev no, txawm hais tias qhov chaw ua haujlwm ib tuj ntawm cov hlau raug txo, kev nyab xeeb ntawm lub tsev yog lav thaum kawg. Steel phaj thinning yuav tsum tau ua nyob rau hauv cov xwm txheej ntawm kev txhim kho lub zog.
Txog txheej txheej
Feem ntau siv cov coatings rau architectural Ppgi Xim Coated Sheets yog kub-dip galvanized thiab kub-dip galvanized. Rau Ppgi Xim Coated Sheets, tsis muaj qhov sib txawv hauv daim ntawv thov ntawm ob lub substrates. Nyob rau hauv ib puag ncig acidic, galvanized substrate yog ib qho kev xaiv zoo dua. Rau kev siv nyob rau hauv cov av noo thiab alkaline ib puag ncig, qhov zoo ntawm galvanized substrate lub incision corrosion kuj yog reflected.
Raws li rau lub thickness ntawm cov txheej, cov kev cai dav dav rau lub ru tsev panels thiab sab nrauv phab ntsa panels yog kub-dip galvanizing Ntau tshaj los yog sib npaug rau 180g / m 2 (li 26μm), galvanized Ntau tshaj los yog sib npaug rau 100g / m 2 (kwv yees 27μm ), thiab kev siv ib puag ncig yog nyob rau hauv ib cheeb tsam kev lag luam hnyav Los yog ntawm ntug hiav txwv, cov koom haum txawv teb chaws muaj qhov tsawg kawg nkaus galvanizing, xws li ECCA cov qauv thiab Australian cov qauv xav tau galvanized txheej hnyav dua lossis sib npaug li 275g / m 2 (kwv yees 38μm), galvanized Ntau dua lossis sib npaug ntawm 150g / m 2 (li 40μm).
Hais txog hom txheej txheej
Feem ntau siv topcoats rau coil txheej muaj xws li polyester (PE), polyurethane (PU), silicon-hloov polyester (SMP), fluorocarbon (PVDF), high weather-resistant polyester (HDP), primers thiab backcoats. Cov ntau hom yog epoxy (EP), polyester (PE), polyurethane (PU) thiab lwm yam.
Hais txog Txheej Xim thiab Gloss
Qhov kev xaiv ntawm cov xim yog tsuas yog xav txog qhov sib txuam nrog ib puag ncig ib puag ncig thiab kev nyiam ntawm tus tswv, tab sis los ntawm kev xav ntawm kev siv thev naus laus zis, lub teeb xim muaj zog muaj peev xwm ua kom muaj cua sov muaj peev xwm thiab qhov sib txawv me me tom qab cov hmoov txheej txheej. Yog tias nws tau ntxuav thiab tswj kom zoo, lub neej kev pabcuam yuav ntev dua. yuav zoo nkauj dua. Rau gloss, nyob rau sab nraum zoov siv cov xim-coated panels, poob ntawm lub teeb yog qhov tshwm sim ntxov tshaj plaws, tshwj xeeb tshaj yog rau cov khoom siv high-gloss, qhov pib poob ntawm lub teeb yuav nrawm heev. Thaum lub glossiness poob mus txog 20, nws yuav kav ntev. Qhov tshwm sim no yuav tshwm sim tom qab ob peb lub hlis ntawm kev siv. Yog li ntawd, cov xim-coated panels rau cov tsev sab nraum zoov feem ntau tsis tshua muaj gloss.
Hais txog Txheej Thickness
Microscopically hais lus, txheej txheej yog ib lub koom haum ntxeem tau. Cov dej hauv huab cua thiab corrosive media (chloride ions, thiab lwm yam) yuav cuam tshuam los ntawm qhov tsis muaj zog ntawm txheej txheej, ua rau corrosion nyob rau hauv zaj duab xis, thiab tom qab ntawd cov txheej yuav blister thiab tev tawm. Tsis tas li ntawd, txawm tias tib lub txheej tuab, cov txheej txheej thib ob yog denser dua li cov txheej txheem thawj. Raws li cov ntaub ntawv xov xwm txawv teb chaws thiab cov txiaj ntsig kev ntsuas corrosion, cov txheej txheem pem hauv ntej tuaj yeem tiv thaiv kev nkag mus ntawm cov xov xwm corrosive yog tias nws muaj ntau tshaj 20 μm. PVDF cov khoom lag luam xav tau cov yeeb yaj kiab tuab dua. Cov kev xav tau rau cov txheej txheem rov qab yog nyob ntawm daim ntawv thov. Lub vaj huam sib luag sandwich tsuas yog yuav tsum tau ib txheej ntawm primer uas tuaj yeem sib koom ua ke, thaum lub phaj tsim steel kuj xav tau ob txheej txheej txheej vim qhov chaw nyob sab hauv tsev, nrog lub thickness ntawm tsawg kawg yog 10 μm.
