Galvanized steel phaj
Kev faib tawm thiab siv
Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no:
1.Alloyed galvanized steel phaj.Hom steel phaj no kuj yog ua los ntawm kub-dip txoj kev, tab sis nws yog rhuab mus rau lub alloy txheej ntawm zinc thiab hlau yog tsim ntawm txog 50O ℃.Qhov no galvanized ntawv muaj zoo txheej adhesion pw ua ke thiab weldability.
2.Kub-dip galvanized steel phaj.Raus cov hlau phaj rau hauv molten Duo zawj kom nws ua raws li ib txheej ntawm Duo steel phaj.
Tam sim no, nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing tas li, uas yog, dov steel phaj yog txuas ntxiv mus rau hauv lub molten zinc plating da dej los ua galvanized steel phaj.
3.Electrogalvanized steel phaj.Cov ntawv hlau galvanized tsim los ntawm txoj kev electroplating muaj kev ua haujlwm zoo.Txawm li cas los xij, cov txheej txheej yog thinner thiab corrosion kuj tsis zoo li cov ntawv kub-dip galvanized;④ Alloy thiab composite galvanized steel phaj.Nws yog steel phaj ua los ntawm zinc thiab lwm yam hlau xws li txhuas thiab zinc.Hom steel phaj no tsis tsuas yog muaj kev ua haujlwm zoo los tiv thaiv xeb, tab sis kuj muaj cov txheej txheem zoo.
4.Ib sab galvanized steel phaj thiab ob sab sib txawv galvanized steel phaj Ib sab galvanized steel phaj, uas yog, cov khoom uas galvanized ntawm ib sab nkaus xwb.Nws muaj qhov hloov tau zoo dua li ob sab galvanized ntawv hauv thee vuam, txheej txheej, kev kho xeb, kev ua haujlwm, thiab lwm yam. Yuav kom kov yeej qhov tsis zoo ntawm tsis txheej zinc ntawm ib sab, muaj lwm hom ntawv galvanized coated nrog nyias. txheej zinc ntawm lwm sab, uas yog, ob npaug thiab sib txawv zinc ntawv.
5.Alloy thiab composite galvanized steel phaj.Nws yog ib lub phaj hlau ua los ntawm zinc thiab lwm yam hlau xws li txhuas, txhuas, zinc, thiab lwm yam. Qhov no steel phaj tsis tsuas yog muaj kev ua haujlwm zoo heev los tiv thaiv xeb, tab sis kuj muaj cov txheej txheem zoo.
Ntxiv rau tsib hom saum toj no, kuj tseem muaj xim galvanized steel phaj, luam ntawv coated galvanized steel phaj, PVC laminated galvanized steel phaj, thiab lwm yam. Txawm li cas los xij, feem ntau siv yog tseem kub-dip galvanized ntawv.
Qhov tshwm sim
1. Ntim
Nws tuaj yeem muab faib ua ob hom: galvanized ntawv txiav rau hauv qhov ntev thiab galvanized ntawv nrog coil.Kev ntim cov ntawv hlau dav dav yog lined nrog cov ntawv pov thawj noo noo, thiab sab nraud yog khi nrog lub duav hlau, uas yog fastened kom ruaj khov los tiv thaiv cov ntawv galvanized sab hauv los ntawm kev sib tsoo.
2. Specification thiab loj
Yam khoom qhov ntev (xws li cov hauv qab no thiab) sau qhov pom zoo qhov ntev, tuab, ntev thiab dav ntawm cov ntawv galvanized thiab lawv qhov tsis xws luag.Tsis tas li ntawd, qhov dav thiab ntev ntawm lub rooj tsavxwm thiab qhov dav ntawm lub yob kuj tuaj yeem txiav txim siab raws li tus neeg siv qhov kev thov.
3. Nto
Qhov xwm txheej dav dav: vim tias muaj cov txheej txheem kev kho mob sib txawv hauv txheej txheej txheej txheej, qhov xwm txheej dav dav ntawm cov ntawv galvanized kuj txawv, xws li qhov xwm txheej ntawm cov zinc flake zoo tib yam, zoo zinc flake, ca zinc flake, zinc-free flake thiab phosphating kev kho mob.Cov ntawv galvanized thiab galvanized coil txiav rau hauv qhov ntev yuav tsum tsis muaj qhov tsis xws luag uas cuam tshuam rau kev siv (raws li tau piav qhia hauv qab no), tab sis cov kauj yuav tsum raug tso cai kom muaj qhov vuam thiab lwm yam tsis muaj qhov tsis zoo.
4. Galvanizing kom muaj nuj nqis
Scale tus nqi ntawm galvanizing kom muaj nuj nqis: galvanizing kom muaj nuj nqis yog ib txoj kev siv dav thiab siv tau los qhia cov thickness ntawm zinc txheej ntawm cov ntawv galvanized.Muaj ob hom zinc plating: tib tus nqi ntawm zinc plating ntawm ob sab (xws li sib npaug thickness zinc plating) thiab qhov sib txawv ntawm zinc plating ntawm ob sab (ie txawv thickness zinc plating).Chav tsev ntawm galvanizing kom muaj nuj nqis yog g / m.
5. Tshuab muaj nuj nqi
(1) Tensile xeem: feem ntau hais lus, tsuav yog daim ntawv galvanized rau layout, kos duab thiab sib sib zog nqus nqus muaj zog tensile yuav tsum.
(2) Kev sim khoov: Nws yog lub npe tseem ceeb los ntsuas qhov kev ua haujlwm ntawm cov phaj nyias.Txawm li cas los xij, cov kev cai ntawm ntau lub teb chaws rau ntau hom ntawv galvanized yog qhov sib txawv.Feem ntau, tom qab daim ntawv galvanized yog khoov 180 °, zinc txheej yuav tsum tsis txhob tawm ntawm qhov profile sab nraud, thiab daim ntawv hauv paus yuav tsum tsis txhob tawg lossis tawg.
Cov yam ntxwv ntawm galvanized steel phaj: galvanizing tuaj yeem tiv thaiv steel corrosion thiab ua haujlwm ntev.Galvanized steel ntawv (thickness 0.4 ~ 1.2mm) kuj hu ua galvanized hlau ntawv, feem ntau hu ua dawb hlau ntawv.Galvanized steel ntawv yog dav siv hauv kev tsim kho, tsheb, khoom siv hauv tsev, khoom siv niaj hnub thiab lwm yam lag luam.
Loj: raws li cov neeg siv khoom xav tau, qhov ntev thiab qhov dav tuaj yeem ua kom flattened lossis customized.
Deg lub xeev: Vim muaj cov txheej txheem kev kho mob sib txawv hauv txheej txheej txheej txheej, lub xeev saum npoo ntawm daim ntawv galvanized kuj sib txawv, xws li zinc flake zoo tib yam, zoo zinc flake, tiaj zinc flake, non-zinc flake thiab phosphating nto.Tus qauv German kuj qhia txog qib saum npoo.
Cov ntawv galvanized yuav tsum muaj qhov zoo nkauj thiab yuav tsum tsis muaj qhov tsis zoo rau kev siv cov khoom, xws li tsis muaj plating, qhov, tawg, scum, dhau plating thickness, khawb, chromic acid av, xeb dawb, thiab lwm yam. Cov qauv txawv teb chaws yog tsis paub meej txog cov tsos mob tshwj xeeb.Qee qhov tsis xws luag yuav tsum tau teev nyob rau hauv daim ntawv cog lus thaum xaj.
Mechanical Properties
Tensile xeem:
1.Performance index: Feem ntau hais lus, tsuas yog daim ntawv galvanized rau cov qauv, kos duab thiab kos duab sib sib zog nqus muaj cov khoom tensile yuav tsum.Cov ntawv galvanized rau cov qauv yuav tsum muaj qhov taw tes tawm, lub zog tensile thiab elongation;Tsuas yog elongation yog yuav tsum tau rau stretching.Saib cov qauv khoom tsim nyog nyob rau hauv "8" ntawm ntu no rau cov nqi tshwj xeeb.
2.Kev xeem txoj kev: nws yog tib yam li cov qauv kev sim rau cov ntawv hlau zoo tib yam, saib cov qauv tsim muaj nyob rau hauv "8" thiab cov qauv kev xeem uas tau teev tseg hauv "Ordinary carbon steel sheet".
Khoov xeem:
Kev sim khoov yog qhov tseem ceeb los ntsuas qhov kev ua tau zoo ntawm cov ntawv, tab sis cov kev cai ntawm ntau lub teb chaws cov qauv ntawm ntau cov ntawv galvanized tsis zoo ib yam.Cov qauv Asmeskas tsis tas yuav tsum tau khoov thiab ntsuas tensile tshwj tsis yog rau qib kev ua haujlwm.Hauv Nyij Pooj, yuav tsum muaj kev sim khoov tshwj tsis yog rau cov qauv, vaj tsev thiab cov phiaj xwm corrugated.
Qhov yuav tsum tau muaj: feem ntau, tom qab cov ntawv galvanized yog khoov 180 °, yuav tsum tsis muaj kev sib cais ntawm zinc txheej rau sab nrauv, thiab yuav tsum tsis txhob muaj qhov tawg thiab tawg ntawm lub phaj puag.
Nta thiab Kev Ua Haujlwm
Xim steel phaj txheej yog cov khoom ua los ntawm txias dov steel phaj, galvanized steel phaj, coated (yob coated) los yog composite organic zaj duab xis (PVC zaj duab xis, thiab lwm yam) tom qab tshuaj kho rau saum npoo, thiab ces ci thiab kho.Qee tus neeg kuj hu cov khoom no "cov menyuam coated steel phaj", "yas xim hlau phaj".Xim phaj cov khoom yog dov los ntawm cov tuam ntxhab ntawm cov kab ntau lawm, yog li lawv tseem hu ua xim coated steel phaj yob.Xim steel phaj tsis tsuas yog muaj zog txhua yam ntawm cov hlau thiab hlau cov ntaub ntawv, yooj yim rau kev ua tau zoo, tab sis kuj zoo zoo nkauj txheej cov ntaub ntawv thiab corrosion kuj.Xim hlau phaj yog cov khoom siv tshiab hauv ntiaj teb niaj hnub no.Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev txhim kho ntawm ib puag ncig kev paub, kev txhim kho ntawm tib neeg txoj kev ua neej nyob, xim steel phaj mobile vaj tse ntau thiab ntau dua qhia tau hais tias muaj zog loj thiab dav kev lag luam zeem muag, los ntawm kev tsim kho, khoom siv hauv tsev, tshuab thiab hluav taws xob, kev thauj mus los. , kho kom zoo nkauj sab hauv, khoom siv hauv chaw ua haujlwm thiab lwm yam kev lag luam nyiam.
