Q: Yuav ua li cas yuav tsum tau ua nyob rau hauv kev xaiv cov tuab ntawm zinc txheej ntawm cov khoom siv tshuaj lom neeg?
A: 1. Yuav tsum muaj cov kev yuav tsum: Qhov nruab nrab thickness ntawm kub-dip galvanizing yog ≥85μm (GB \/ T 13912), thiab cov tuab yuav nce ntxiv los ntawm 20% {% nyob rau hauv ib puag ncig tshwj xeeb.
2. Txheej txheem xaiv: Nqus zinc infiltration yog nyiam rau cov kev kub siab lossis cov txheej txheem nyuaj, thiab zinc txau tiv thaiv yog siv rau cov khoom sib chwv.
3. Cov Thawj Coj Txheej Txheem: Tshaj dhau ntsev txau ntsuas (≥9 teev kom ntseeg tau tias qhov zoo ntawm zinc txheej ua tau raws li qhov yuav tsum tau ntawm ISO 1461 lossis ISO 12944.
Q: Hais txog kev tiv thaiv corrosion kuj yuav tsum muaj tshuaj lom neeg siv tshuaj, cov qauv kev lag luam rau kev xaiv cov txheej zincness?
A: Lub teb chaws tus qauv (GB \/ t 13912-2020)
Tsis-centrifugal seem nrog hlau thickness> 6 hli: hauv zos tuab ≥70μm, qhov nruab nrab tuab ≥85μm.
Cov khoom siv los yog centrifugally kho qhov chaw: cov tuab hauv zos thickness ≥40μμ, qhov nruab nrab tuab ≥50μm (siv rau xov kab, thiab lwm yam).
Cov txheej txheem corrosive (xws li cov txheej txheem tshuaj lom neeg): lub zinc txheej thickness xav tau nce los ntawm 20% {% rau qhov no.
Cov Txheej Txheem Thoob Ntiaj Teb (ISO 1461: 2022)
Kev siv tshuaj tua hluav taws xob: Thaum lub tshuab tuab hlau loj dua 6 hli, nruab nrab Zinc Txheej Thickness yog ≥85μm, thiab lub zos thickness yog ≥70μm 12.
Cov ntaub ntawv tshwj xeeb (xws li ultra-qis tshuaj tiv thaiv hlau): qhov ua tau siab dua yuav tsum ua raws.
Q: Yuav ua li cas xaiv cov tuab ntawm zinc txheej rau cov khoom siv tshuaj lom neeg raws li cov chaw corrosion sib txawv?
A: Kev Nyuaj Siab: Cov Khoom Siv Hluav Taws Xob: Kev Tshawb Fawb Ntsev, Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
High Industrial: Muaj zog acid \/ alkali post, siab av noo, muaj zog sulfide ≥100μm, lossis Nqus Zincizing {2} μm.
Cov tub rog siab heev: Nqaum siab cov ntsev tsuag, foob pob hluav taws kub, hluav taws kub falvanizing ≥120μm, lossis zinc-alloy txheej.
Q: Yuav ua li cas los xaiv cov txheej zinc txheej hauv cov xwm txheej tshwj xeeb?
A: 1. Kev kub siab ib puag ncig (xws li reactors, pipelines)
Cov txheej txheem pom zoo: Lub tshuab nqus tsev Dilcaltration (Zinc-}}} μm), zam oxidation thiab tev ntawm zinc txheej ntawm qhov kub thiab txias.
2. Cov cuab yeej sib cuag tau (xws li tso tsheb hlau luam, reactors)
Kev tiv thaiv phab ntsa sab hauv: zinc txau txheej tuab {{}}}}}} ≥400μm), tuaj yeem tiv thaiv muaj zog acid \/ alkali ua kua xeb.
Hauv qab phaj tiv thaiv: Zinc Txheej tuab yuav tsum yog ≥350μm, thiab kev tiv thaiv kev tua tsiaj anode.
3. Lub siab-zog hlau lossis cov txheej txheem nyuaj
Cov txheej txheem pom zoo: Lub tshuab nqus tsev Dinc Infiltration (thickness {{{} μm), vim nws txhim kho cov khoom sib txawv ntawm lub ntsej muag zoo nkauj (HV400 lossis siab dua).
Q: Lwm txoj kev xaiv rau corrosion tsis kam hauv kev lag luam tshuaj lom neeg?
A: Galvalume:
Zinc-aluminium alloy txheej (55% txhuas, 43.4% dhuav (° Corroson), tshwj xeeb ° C) thiab sulphur-muaj cov khoom siv Petrochemical (.
Daim Txheej (Galvanizing + Txau):
Txau cov tshuaj tiv thaiv xeb xws li epoxy thiab polyurethane ntawm qhov kub-dip galvanized txheej muaj peev xwm txuas ntxiv cov kev pabcuam lub neej (xws li offshore platform khoom).
Tu txij nkawm:
Txheeb xyuas kev ncaj ncees ntawm cov txheej thiab siv Zinc-raws li kev kho cov xim uas txias (xws li txias-dip galvanizing xim) los kho cov kev puas tsuaj hauv zos hauv lub sijhawm.
