SPCChlau phaj
SPCC steel phaj yog atxias dov carbon steel phajtau teev nyob rau hauv Japanese Industrial Standard (jis g 3141).Nws lub npe tag nrho yog "steel phaj txias dov ua lag luam zoo", qhov twg spcc sawv cev rau cov yam ntxwv thiab siv cov phaj steel: s sawv cev rau cov hlau., p txhais tau tias cov phaj tiaj tus, c txhais tau tias yog qib lag luam, thiab qhov kawg c txhais tau tias kev ua haujlwm txias.Cov phaj hlau no yog cov phaj hlau uas tsis tshua muaj carbon feem ntau siv los ua cov khoom rau cov tub yees tshiab, cov tub yees txias lossis cov khoom siv conveyor rau cov tsheb tsis siv neeg.Cov phaj hlau no muaj kev sib sau zoo heev thiab stamping zog, thiab tuaj yeem ua tiav los ntawm kev sib sib zog nqus txias stamping.Vim nws cov ntsiab lus carbon tsawg, nws muaj cov khoom siv tsis zoo, tab sis muaj cov yas zoo, ua rau nws yooj yim thiab yooj yim rau cov duab sib txawv.Txawm hais tias spcc steel phaj tsis haum rau cov ntawv thov uas xav tau lub zog siab dua, nws tseem siv dav hauv ntau qhov kev lag luam xws li cov khoom siv hauv tsev thiab tsheb.Nyob rau tib lub sijhawm, cov khoom siv no kuj muaj kev tiv thaiv corrosion zoo heev thiab tau siv dav hauv qee lub sijhawm nrog cov kev xav tau siab heev.
Kev kho saum npoo ntawm spcc steel phaj tuaj yeem ua tau ntau txoj hauv kev.Nov yog qee txoj hauv kev:
Kev tu neeg kho tshuab: Siv cov cuab yeej xws li txhuam hlau los yog cov ntawv xuab zeb los txhuam thiab yaug qhov chaw kom tshem tawm cov av xws li xeb thiab roj.
Kev kho tshuaj lom neeg: siv cov kua qaub, alkali lossis lwm yam tshuaj reagents kom yaj lossis hloov cov oxides los yog lwm yam impurities rau hauv cov khoom siv kom huv si kom ua tiav lub hom phiaj ntawm kev ntxuav qhov chaw.
Electroplating kev kho mob: Hlau plating yog ua nyob rau saum npoo ntawm steel phaj los ntawm electrolysis los tsim ib txheej ntawm hlau tiv thaiv txheej los txhim kho nws corrosion kuj thiab zoo li.
Txheej kev kho mob: Txau ntau yam xim ntawm cov xim pleev xim rau saum npoo ntawm spcc steel phaj ua si los tiv thaiv corrosion thiab kev ua kom zoo nkauj.
Cov txheej txheem kev kho deg sib txawv yog tsim rau cov kev xav tau sib txawv.Xaiv txoj kev tsim nyog los kho qhov saum npoo ntawm spcc steel phaj raws li qhov xwm txheej tiag tiag tuaj yeem txuas ntxiv nws lub neej kev pab cuam thiab tswj cov khoom siv kho tshuab zoo heev.
SECC steel phaj
Lub npe tag nrho ntawm SECC yog Hlau, Electrolytic Zinc-coated, Cold Rolled Steel Chev, uas yog cov hlau phaj uas yog electrolytically galvanized tom qab txias dov.Qhov saum npoo yog electrolytically galvanized kom muaj kev tiv thaiv corrosion zoo dua thiab zoo nkauj.Nws feem ntau yog siv los tsim cov khoom lag luam uas tsis tshua muaj kev tiv thaiv corrosion thiab cov kev xav tau zoo nkauj, xws li cov khoom siv hauv tsev, cov twj paj nruag, thiab lwm yam.
SECC galvanizing txoj kev:
Kub Dipped Galvanized Coil: Kub-dip galvanizing yog ib qho kev tiv thaiv corrosion uas tsim cov zinc txheej ntawm cov hlau.Nws yog txhawm rau txhawm rau cov hlau los yog cov hlau rau hauv cov kua zinc uas yog preheated rau qhov kub thiab txias (feem ntau yog 450-480 degrees Celsius), thiab tsim ib lub thicker thiab ntom zinc-hlau alloy txheej rau ntawm qhov chaw ntawm cov hlau los ntawm cov tshuaj tiv thaiv.Tiv thaiv steel qhov chaw los ntawm corrosion.Piv nrog electrolytic galvanizing, kub-dip galvanizing muaj ntau dua corrosion kuj thiab kev pab lub neej ntev, thiab feem ntau yog siv los tsim cov khoom tseem ceeb xws li cov qauv loj, nkoj, txuas hniav, thiab cov khoom siv hluav taws xob.
Nruam galvanizing txoj kev: Rolled steel los xij yog txuas ntxiv rau hauv lub plating da dej uas muaj zinc yaj.
Phaj galvanizing txoj kev: Cov phaj hlau txiav yog muab tso rau hauv lub plating da dej, thiab yuav muaj zinc spatter tom qab plating.
Txoj kev electroplating: electrochemical plating.Muaj zinc sulfate tov nyob rau hauv lub plating tank, nrog zinc raws li cov anode thiab thawj steel phaj li cathode.
SPCC vs SECC
SECC galvanized steel ntawv thiab SPCC txias dov steel ntawv yog ob yam khoom sib txawv.Ntawm lawv, SECC hais txog electrolytically galvanized txias-kuav los tiag steel nplooj ntawv, thaum SPCC yog ib tug universal txias-kuav los tiag steel ntawv txheej txheem.
Lawv qhov sib txawv tseem ceeb yog:
Lub cev muaj zog: SECC muaj zinc txheej thiab muaj kev tiv thaiv corrosion zoo dua;SPCC tsis muaj txheej tiv thaiv corrosion.Yog li, SECC yog qhov ruaj khov dua li SPCC thiab tiv thaiv xeb thiab xeb.
Kev kho deg: SECC tau dhau los ntawm electrolytic galvanizing thiab lwm yam kev kho mob, thiab muaj qee qhov kev kho kom zoo nkauj thiab zoo nkauj;thaum SPCC siv cov txheej txheem txias dov yam tsis muaj kev kho deg.
Kev siv sib txawv: SECC feem ntau yog siv los tsim cov khoom lossis cov khoom siv hauv cov khoom siv hluav taws xob, tsheb, thiab cov khoom siv hauv tsev, thaum SPCC tau siv dav hauv kev lag luam xws li kev tsim kho, tsim khoom, thiab ntim khoom.
Nyob rau hauv luv luv, txawm hais tias ob qho tib si yog txias-kuav los tiag steel daim hlau nyob rau hauv cov nqe lus ntawm cov txheej txheem Cheebtsam, muaj ib tug tseem ceeb sib txawv nyob rau hauv lawv cov anti-corrosion zog, nto kho thiab siv.Kev xaiv ntawm SECC lossis SPCC steel phaj yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb, suav nrog ntau yam xws li kev siv cov khoom tsim, ib puag ncig thiab kev xav tau tiag tiag, thiab xaiv cov khoom tsim nyog tshaj plaws.
