Hauv cov ntawv cog lus tshiab 2019 Xinyu xim pawg thawj coj saib zhengzhou chaw nres tsheb khoom txhawb nqa lub rooj sib tham, xinyu tshiab tiam zinc plating, aluminium magnesium board thiab Tianyu tsiaj lub rooj tsav xwm cov khoom lag luam, ntawm nws tus kheej tau tsim los ntawm Xinyu technical pab neeg, tau tshwm sim hauv lub rooj sib tham loj hauv kev tshaj tawm.
Txij li thaum xyoo 2012, Tianjin Xinyu tau teeb tsa lub chaw kuaj kab mob los tshawb nrhiav thiab tsim cov khoom plating; Hauv xyoo 2015, cov qauv ntawm galvanized aluminium thiab magnesium cov khoom tau txiav txim siab. Xyoo 2016, Xinyu ua tiav kev sim thiab daim ntawv thov kev soj ntsuam ntawm galvanized aluminium thiab magnesium cov khoom lag luam.Hauv xyoo 2018, kev sim zaum thib ob thiab kev thov kev ntsuam xyuas tau ua tiav.Hauv xyoo 2019, nws yuav ua tiav tso rau hauv ntau lawm.
Kaum xyoo ua rau rab ntaj zoo nkauj, zoo siab plum paj tawg paj xyoob.Xinyu 7 xyoo, kev ua haujlwm ntawm kev ua tau zoo, zoo tshaj plaws ntawm lub cim tshiab ntawm galvanized aluminium thiab magnesium phaj thiab tsiaj txhu cov khoom lag luam yuav tau nthuav tawm rau hauv khw.
Los ntawm ZAM mus rau superdyma
Nrog rau kev tsim cov khoom siv steel thiab nrog polish plating thev naus laus zis, kev ua lag luam rau txheej ntawm steel corrosion tsis kam tso rau hauv kev thov siab dua, cov tsoos kub dip galvanized txheej steel twb tsis txaus siab rau daim ntawv thov yuav tsum tau, magnesium nyob rau hauv daim ntawv thov ntawm kub dip plating tuaj yeem tau taug qab mus txog xyoo 1960 s, siab corrosion kuj ntawm zinc - Al - Mg alloy txheej los ua lub ntsiab lus tseem ceeb ntawm txoj kev loj hlob ntawm thaj teb ntawm cov khoom siv txheej, txheej txheej thiab zinc txhuas thiab magnesium kev lag luam tau pib thaum xyoo 1990 s hauv Nyij Pooj, Japanese nissin steel tau tsim nyob rau hauv 1988 zinc - Al - Mg alloy txheej, thiab ZAM lub cim tau sau npe.
Lub peev xwm ntawm kev thov ntawm ZAM txheej hauv tsheb tau tshawb nrhiav tam sim ntawd tom qab ZAM txheej tau qhia los ntawm Nissin steel.
Raws li lub sijhawm dhau los, Nippon Nippon Steel Corporation ntawm Nyij Pooj, tom qab kev tshawb fawb txuas ntxiv, tsim thiab tsim cov alloying txheej ntawm Zn-11% al-3% MG-0.2% Si thiab npe nws Superdyma. Nws yog cov xim coated steel phaj nrog siab corrosion kuj thiab cov cuab yeej kho tus kheej.
Tam sim no, galvanized aluminium magnesium phaj feem ntau yog siv hauv kev ua liaj ua teb tsiaj txhu kev tsim, kev tsheb nqaj hlau, tsheb tsheb, kev lag luam tub yees thiab lwm yam kev lag luam, kev siv cov liaj teb dav.
Xinyu tshiab tiam galvanized aluminium magnesium phaj
Xinyu lub cim tshiab ntawm cov khoom tsim cov txheej txheem txheej txheem, feem ntau yog siv cov zinc, aluminium thiab magnesium thiab lwm yam ntawm cov qauv zoo meej ntawm galvanized aluminium magnesium alloy phaj, hu ua YAM.
Kev ntsuam xyuas tiv thaiv corrosion mechanism tawm
Ntau qhov kev sim tau pom tias Xinyu YAM lub rooj tsavxwm tsis tsuas yog muaj kev txhim kho corrosion zoo heev, tab sis kuj muaj cov cuab yeej zoo rau kev kho tus kheej.Qhov chaw: Qhov kev txiav txim siab ua ke ntawm zinc, txhuas thiab magnesium tsim ua tuab thiab xaj oxide zaj duab xis nyob rau saum npoo ntawm phaj; Qhov chaw txiav txim siab: Ntxiv cov magnesium los ua kom tus kheej txhim kho kev ua haujlwm, ua ke nrog zinc thiab txhuas, zoo heev txhim kho kev phais tiv thaiv kev ua tau zoo.Qhov no yog vim peb ntxiv ib qho kev faib ua feem ntawm Mg rau hauv cov khoom, txheej txheej yuav tsim kev ruaj khov tiv thaiv. txheej txheej uas muaj Mg Zn thiab ZnAl, uas ua rau qeeb qeeb ntawm kev xeb ntawm txheej txheej.
Ntsev cov tshuaj tiv thaiv corrosion test.2500 teev
Xeem xaus:
Tiaj tiaj: YAM phaj ntsev tshuaj tsuag rau kev ntsuas yog zoo li 55% txhuas-zinc phaj;
Kev txiav txim feem: YAM board ntsev txau cov tshuaj tiv thaiv kev ntsuas yog qhov ua tau zoo dua li 55% aluminium-zinc phaj thiab galvanized phaj.
YAM phaj muaj cov ntsev tiv thaiv zoo tiv thaiv.
Acid thiab alkali tsis kam kuaj
Tom qab kuaj, nws xaus lus tias thaum PH tus nqi yog nyob rau hauv thaj tsam ntawm 4-10, zinc txheej poob ntawm YAM steel phaj yuav luag 0, uas zoo dua li kub-dip galvanized steel phaj thiab txhuas-zinc plated steel phaj. Thaum PH tus nqi yog> 10, zinc txheej poob ntawm YAM steel phaj tau zoo dua li cov kub-dip galvanized steel phaj thiab aluminium-zinc plated steel phaj, uas qhia muaj zog alkali tsis kam.Thaum PH tus nqi tsawg dua 4, zinc txheej poob ntawm YAM steel yog nruab nrab ntawm aluminium-zinc phaj thiab kub-dip galvanized steel phaj.
Raws li cov kev sim saum toj no, acid thiab alkaline tsis kam ntawm YAM steel phaj ntawm lub cim tshiab ntawm Xinyu yog zoo dua. Yog li no, Tianyu Tsiaj txhu pawg thawj coj kuj tseem muaj kua qaub zoo thiab alkaline tsis kam.
