Galvanized steel coils ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam, muab kev tiv thaiv corrosion thiab ntxiv cov kav ntev rau ntau yam kev siv. Galvanized steel kauj yog tsim los ntawm galvanizing SPCC (txias-rolled steel kauj). SPCC yog ib qho pheej yig thiab yooj yim muaj steel coil paub txog nws txoj kev ua haujlwm zoo, uas ua rau nws nyiam xaiv rau ntau yam txheej txheem xws li khoov thiab nyem. Txawm li cas los xij, SPCC muaj qhov cuam tshuam rau xeb thiab feem ntau xav tau qee yam kev kho saum npoo.
Muaj ntau qib muaj.SECC(electro-galvanized steel kauj) thiabSGCC(kub-dip galvanized steel kauj) yog ob qho kev xaiv nrov nrog cov yam ntxwv sib txawv thiab kev siv.
SPCC (Steel Coil Cold Commercial)
SPCC Steel coil - Cold rolled steel coil rau kev siv dav dav, uas yog sib npaug rau Suav Q195-215A qib lossis St12 hauv German Standard. S ntawm no yog rau hlau, thiab P yog rau phaj; C yog rau txias thiab qhov kawg C yog rau kev lag luam zoo.
SGCC (Kub-dip Galvanized Steel Chev)
SGCC txais cov txheej txheem kub-dip galvanizing, muab cov ntawv hlau rau hauv cov zinc molten los ua ib txheej zinc- hlau alloy. Cov txheej txheem no muab cov ntawv hlau muaj zog corrosion kuj.
SECC (Electrolytic Galvanized Steel Chev)
SECC yog electrogalvanized txias-rolled steel ntawv. Ib txheej ntawm zinc yog tsim rau ntawm nws qhov chaw los ntawm cov txheej txheem electrolytic galvanizing. Cov txheej ntawm zinc no tsis tsuas yog txhim kho cov ntawv hlau corrosion tab sis kuj txuas ntxiv nws lub neej kev pab cuam.
Qhov sib txawv ntawm SPCC, SGCC thiab SECC
SPCC yog qhov txias tshaj plaws -rolled steel kauj. Nws tsis yog galvanized thiab nws nto feem ntau yog dub thiab ntxhib.
Txoj kev ua:Cov txheej txheem tsim khoom ntawm SPCC yog qhov yooj yim thiab tus nqi qis, haum rau loj - nplai ntau lawm.
SGCC(Kub-Dip Galvanization): Kub-dip galvanization yuav immersing steel coils hauv molten zinc tom qab cua sov. Cov txheej txheem no tsim cov txheej txheej tuab thiab tsim cov txheej txheej txheej ntawm zinc thiab lub hauv paus hlau, uas ua rau muaj qhov tshwj xeeb durability thiab ntev - lub sij hawm corrosion kuj. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kub thiab txias tuaj yeem ua rau muaj cua sov- ua rau muaj kev cuam tshuam, ua rau muaj teeb meem hauv qee yam kev siv.
SECC(Electro-Galvanization): Electro-galvanization siv hluav taws xob tam sim no los tso cov zinc yaj mus rau saum npoo ntawm cov khoom yuav tsum tau plated. Txoj kev no muaj cov txheej txheej tuab tuab thiab cov khoom zoo nkauj, ua rau nws xaiv rau ntau yam kev siv. Tsis zoo li kub-dip galvanization, electro- cov ntaub ntawv galvanized feem ntau tau txais kev kho chromate los txhim kho corrosion thiab tiv thaiv cov hmoov dawb paug.
Kev sib piv
Corrosion Resistance
Ob leeg SECC thiab SGCC muaj qhov zoo corrosion kuj vim kev kho galvanizing. Ntawm lawv, SGCC muaj zog corrosion kuj me ntsis vim qhov kub -dip galvanized txheej yog tuab dua thiab zoo ib yam.
SPCC muaj kev tiv thaiv corrosion tsis zoo thiab yuav tsum tau muaj kev tiv thaiv ntxiv - kev kho corrosion thaum siv.
Lub zog thiab Toughness
SGCC muaj lub zog zoo thiab toughness, haum rau kev tsim cov khoom uas dais loj.
SECC kuj muaj lub zog zoo thiab tawv, ua tau raws li qhov xav tau ntawm cov khoom siv hauv tsev feem ntau.
SPCC muaj lub zog tsis tshua muaj zog thiab tawv tab sis tsim nyog rau kev tsim qee cov ntaub ntawv nyias.
Nto thiab Nto Zoo
Qhov saum npoo ntawm SECC yog du thiab ci, haum rau cov khoom uas muaj qhov xav tau siab.
Qhov saum npoo ntawm SGCC cov ntaub ntawv spangle thiab muaj qhov ci ntsa iab tab sis muaj qhov pom kev tshwj xeeb.
Qhov saum npoo ntawm SPCC feem ntau yog xim dub thiab ntxhib, xav tau kev kho mob ntxiv kom ua tiav qhov zoo tagnrho.

Kev tsim kho kev lag luam
SECC: Vim nws qhov chaw du thiab zoo heev corrosion kuj, SECC steel kauj yog dav siv nyob rau hauv kev tsim cov khoom siv hauv tsev, xws li lub plhaub sab nraud ntawm lub tub yees, tshuab ntxhua khaub ncaws, thiab cua txias, nrog rau cov khoom siv hluav taws xob thiab cov chassis.
SGCC: Nrog nws lub zog siab, siab tawv, thiab zoo corrosion kuj, SGCC steel coil yog siv rau hauv ntau yam xws li cov khoom siv hauv tsev, cov khoom siv hluav taws xob tsawg, kev kho kom zoo nkauj hauv tsev, thiab kev tsim tsheb, xws li lub qhov rooj ruaj ntseg, guardrails, thiab conveyor siv.
SPCC: Vim nws cov nqi qis, SPCC steel coil feem ntau yog siv los tsim cov khoom lag luam uas tsis tshua muaj kev tiv thaiv corrosion, xws li cov kaus poom, hauv qab, cov kav hlau, thiab cov ntsiav tshuaj.
SECC yog cov hlau uas tau dhau los ntawm electrolytic zinc plating siv rau SPCC (txias-rolled steel coil), thaum SGCC yog cov hlau uas tau dhau los kub-dip galvanizing siv rau SPCC. Ob leeg cov ntaub ntawv tsim nyog rau kev siv xws li hluav taws xob enclosures thiab cov khoom siv hauv tsev vim tias lawv muaj kev tiv thaiv corrosion thiab yooj yim rau kev ua haujlwm.
