Taw qhia rau Spcc - gi
Spcc - gi yog kub - dip galvanized txias siv nyob rau hauv kev lag luam uas yuav tsum tau corrosion tsis kam. Nws lub npe yog kev sib xyaw ntawm cov khoom siv, ua cov thev naus laus zis, thiab hom txheej. Nws cov yam ntxwv tshwj xeeb yog li hauv qab no:
I. Lub npe ntsiab lus
Spcc: muab tau los ntawm tus qauv Japanese (sib raug rau International ISO tus qauv), nws sawv rau "txias {} {rolled carbon steel ntawv thiab sawb rau kev siv dav dav." Qhov twg:
S: Hlau;
P: phaj;
C: Txias;
C: Kev lag luam lag luam.
Cov ntaub ntawv yog tsawg -} cov ntsiab lus tsawg dua los yog sib npaug {{rolling proding (xws li stamping thiab dabtsi yog khoov).
GI: galvanized los ntawm kev raus dej, xa mus rau "kub - dip galvanizing." Qhov no cuam tshuam nrog txias- Rolling cov ntawv steel thiab tom qab ntawd raus nws hauv Molrening Zinc (kwv yees li 450℃zinc txheej rau saum npoo. Cov txheej txheej txheej txheej tuab yog li 5-25μm (kho tau nyob ntawm corrosion tsis kam). Ii. Yam ntxwv
Zoo tshaj plaws corrosion:
Cov txheej zinc zinc ua raws li kev ua kom muaj kev tua tsiaj, tiv thaiv cov hlau substrate los ntawm nws tus kheej corrosion. Hauv cov chaw qhuav, nws muaj kev ua kom muaj lub neej ntawm 10 - 20 xyoo. Hauv nooly corrosive ib puag ncig (xws li nyob sab hauv tsev thiab hauv qhov tsis yog}}} huab cua ntug dej hiav txwv txias-rolled steel ntawv (SPCC).
Kev ua tiav zoo:
Tau txais cov stamping zoo, khoov, thiab vuam cov khoom ntawm txias {{rolled steel ua cov txheej txheem (xws li cov cuab yeej siv hluav taws xob tsheb thiab cov khoom siv bending). Txawm li cas los xij, ceev faj yog qhia: zinc txheej yog nkig, thiab kev cuam tshuam ntau dhau los yog kev cuam tshuam loj tuaj yeem ua rau tawg lossis npau taws. Kev deformation yuav tsum tau tswj thiab txheej yuav tsum muaj kev tiv thaiv thaum ua.
Uniform nto:
Tom qab kub -}} dip galvanizing, saum npoo yog silvery dawb (lossis me ntsis spangled) thiab muaj ib qho zoo li cas. Nws tuaj yeem siv ncaj qha rau hauv cov ntawv thov kom zoo nkauj (xws li cov txheej txheej ua kom zoo nkauj (cov khoom siv ua kom zoo nkauj (cov txheej txheem zoo tshaj plaws rau cov xim). Tus nqi nruab nrab:
Piv rau electrogalvanized steel (Secc), GI muaj ib qho tuab me me, ua rau nws tus nqi qis dua nrog tus nqi sib npaug nrog tus nqi sib npaug nrog tus nqi sib npaug nrog lub ntsej muag sib piv.
III. Cov ntawv thov MAIN
Automotive: panels lub cev (xws li lub qhov rooj thiab hood interiors), chassis Cheebtsam, thiab siv cov nplaim hluav taws xob, thiab lwm yam kom txo tau xeb.
Cov khoom siv hauv tsev: vaj yees duab sab vaj tsev, tshuab ntxhua khaub ncaws, cua txias sab nraum zoov chav tsev, thiab lwm yam, ntsuas hluav taws xob tsis kam thiab tsos.
Architecture thiab cov qauv tsim: cua ntxhib cov qauv steel, cov neeg zov me nyuam, tsim nyog rau thaj chaw sab nraud thiab sab nraum zoov.
Cov Khoom Kho Vajtse: cov cuab yeej siv, txee, hlau Xwm, thiab lwm yam., Xav tau ntev- siv thiab corrosion tsis kam.
IV. Sib txawv ntawm cov ntaub ntawv zoo sib xws
Spcc (Ungalvanized): Tsis muaj corrosion tsis kam thiab tsuas yog tsim nyog rau qhuav, tsis {{corrosive ib puag ncig (xws li rooj tog kom haum).
Secc (electrogalvanized): muaj ib txheej nyias nyias (feem ntau 3 -}}}} {3} pretion {Precision hluav taws xob. SGCC (kub - dip galvanized kub {} {dov steel ntawv, SGCC muaj qhov chaw ua haujlwm kub thiab qis dua SPCC-GI. Nws yog feem ntau siv rau cov txheej txheem txheej txheem (xws li nkhaus thiab kav dej).
Hauv cov ntsiab lus, Spcc - gi, nrog nws cov khoom siv sib xyaw ua ke ntawm cov khoom lag luam txias, muaj feem sib npaug thiab cov kev yoog raws ib puag ncig.
