1.How los xaiv hom ntawm galvanizing?
Nce cov txheej thickness: qhov no yog ib txoj kev ncaj qha thiab muaj txiaj ntsig. Xaiv cov txheej luv Thicker zinc Txheej txhais tau ntau dua kev tiv thaiv kev tiv thaiv.
Zinc-aluminium txheej: Qhov no yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws los txhim kho corrosion tsis kam. Ntxiv txhuas thiab magnesium rau Zinc Tsim ib txheej nrog: Mix-compited thiab Zinc-Magnesium Hydroxide) uas zoo dua blocks chloride ion thiab oxygen nkag. Muaj kev tiv thaiv ntau dua rau kev tiv thaiv kab mob anode. Zoo heev tiv thaiv kom txiav-ntug corrosion thiab kos corrosion. Hauv cov ntug dej hiav txwv ntsev ib puag ncig, nws corrosion kuj feem ntau yog 2-10 npaug uas ntawm cov kub dog kub-dip galvanizing.
Galvalume: Txhuas muab txoj kev tiv thaiv zoo heev (oxidation thiab tshuaj lom neeg Kuj) thiab Zinc muab kev tiv thaiv kab mob fij. Hauv cov ntug dej hiav txwv, nws txoj kev tiv thaiv kom xeb ntau dua li qhov zinc txhuas tsis zoo yog tsis zoo li cov tshuaj ntsuab zoo nkauj tsis zoo, thiab nws txiav tiv thaiv av tsis zoo. Cov xeb dawb xeb kuj yuav tsis zoo li cov malvanizing galvanizing.
High zinc Alloy Alloy: Cov ntsiab lus Zinc yog siab dua li ntawm Aluminium-zinc alloy, nws muaj kev tiv thaiv zoo dua, thiab nws cov kev ua tau zoo yog nruab nrab ntawm Galvanizing thiab Aluminium-Zinc.
2.Yog li cas rau kev ua kom zoo saum npoo?
Zoo siab passivation:
Chromium-dawb passiveation: cov kev xaiv tseem ceeb tshaj plaws nyob rau hauv ib puag ncig kev tiv thaiv. Xaiv cov tshuaj chromium-pub dawb passivation optimized ib cheeb tsam chaw ib puag ncig (titanium / zirconate, molybdate, phosphate, thiab lwm yam). Cov duab skeeiv no tuaj yeem ncua kev tsim cov xeb dawb thiab txhim kho thawj zaug corrosion tsis kam.
Trunticent Chromium Passivation: Qhov kev ua tau zoo dua Hexavalent Chromium passive, ntau ib puag ncig tus phooj ywg, thiab muaj zoo corrosion tsis kam.
3.Yog li cas lub luag haujlwm tiv thaiv kev ua si?
Organic Sealer: ib txheej nyias nyias ntawm cov pob tshab organic (xws li cov dej-raws li acrylic, polyurethane, epoxy cob, thiab lwm yam) yog thov ntawm txheej passivation. Zaj duab xis no tuaj yeem kho lub cev corrosive corrosive corrosive, ho ncua dawb xeb thiab pib xeb, thiab tswj kev zoo nkauj. Qhov no yog qhov raug nqi-ua tau zoo thiab feem ntau siv txoj kev los txhim kho cov avast corrosion.
Cov xim xim txheej: Rau cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv ntau dua lossis xim tshwj xeeb, ua kom tiav cov txheej galvanized. Nco ntsoov xaiv qhov primer uas tau sib haum nrog lub galvanized substrate (xws li epoxy zinc-eptated txheej txheem (xws li huab cua zoo heev (xws li polyuretholarbon. Qhov no muab ob chav kev tiv thaiv (tshuaj rau anode + Barrier tiv thaiv).
4.How peb tuaj yeem txhim kho cov qauv tsim thiab teeb tsa?
Zam kev txo cov dej tsub zuj zuj: thaum tsim cov khoom siv, xyuas kom cov khoom siv kom tsis txhob muaj dej ntws ntev ntawm cov dej nag thiab cov hws hauv grooves thiab khoob. Them sai sai rau kev tso kua dej thaum khawb. ◦ Txo cov gaps: sim kom tsis txhob muaj qhov sib txawv ntawm qhov khoob (xws li overlaps ntawm cov phaj hlau), uas yog nquag los ua cov hlwb kaw thiab ua kom muaj zog. Siv cov foob los sau qhov sib tw. ◦ Zam zam kev sib cuag ntawm cov hlau cais: yog tias galvanized steel yuav tsum muaj peev xwm ntau dua siv cov pa roj hlau lossis lub tes tsho, txwv tsis pub nws yuav ua rau nws muaj peev xwm ua rau nws muaj peev xwm ua rau muaj cov roj av. ◦ Qhov cua: Xyuas kom zoo qhov chaw tso pa tawm hauv cov qauv los txo cov av noo thiab ua kom ziab kom qhuav. ◦ Tiv thaiv cov npoo txiav thiab cov qhov chaw ua haujlwm: cov chaw no muaj cov txheej thinnest zinc lossis raug puas. Lawv tuaj yeem ua tib zoo kho nrog zinc-nplua nuj xim (txias galvanizing xim) los muab kev tiv thaiv ntxiv.
5.Qhov lwm cov kev ntsuas yuav ua tau los txhim kho nws?
Kev fij rau cov khoom noj khoom haus (xws li cov qauv hluav taws xob (xws li cov khoom tsis zoo ntawm lub zog
Kev tiv thaiv tam sim no tam sim no (feem ntau yog siv rau cov qauv loj lossis faus / hauv qab, cov kev tiv thaiv tam sim no yog muab los ntawm kev tiv thaiv sab nraud. Nws tsawg dua siv hauv cov dej hiav txwv atmospheric.
