Dab tsi yog qhov chaw zoo ntawm s235jr galvanized khoom?
Qhov chaw zoo ntawm s235jr galvanized khoom (feem ntau kub {{1} Kev tswj galvanizing; Zuag qhia tag nrho, nws ua rau cov kev sib luag, txuas ntxiv, thiab qee yam kev tiv thaiv thiab kev ua kom zoo nkauj. Qhov no yog qhia tshwj xeeb raws li hauv qab no:
1. Qhov xwm txheej thiab tsos
Kev zoo ib yam ntawm kub - dip galvanizing: qhov chaw nyob ib txwm muaj cov khoom sib dhos nrog cov xim av thiab muaj kev sib dhos. Qhov no yog vim zinc txheej rov qab nrog lub hauv paus hlau ntawm kev kub siab rau ua ib txheej zoo nkauj (sab hauv txheej zinc (sab hauv txheej). Tom qab txias, ib qho chaw ua haujlwm txuas ntxiv saum npoo av yog tsim.
Cov khoom siv nquag: Cov nplaim hluav taws xob tuaj yeem muaj cov kab mob zoo "zinc Cov qauv no tau tsim los ntawm cov qauv siv lead ua thaum kub- dip galvanizing cov txheej txheem, raws li zinc daws cov tshuaj txias. Qhov loj me ntawm cov spangles tuaj yeem hloov kho los ntawm cov txheej txheem tswj (xws li ntxiv cov ntsiab lus thiab kho tus nqi txias). Qhov no tsis cuam tshuam rau cov khoom tiv thaiv thiab tej zaum kuj tau suav tias yog ib qho kev zoo nkauj hauv qee qhov xwm txheej . 2. coating txuas ntxiv thiab muaj kev ncaj ncees
Qhov kub - dip galvanizing cov txheej txheem ua tiav cov npoo, yog tias muaj kev tiv thaiv cov roj av, tshwj tsis yog cov khoom siv tsis zoo lossis tsis tiav ntxuav), ua kom muaj kev tiv thaiv zoo.
Cov txheej zinc zinc tau sib khi kom nruj rau cov txheej txheem (metallurgically sib khi), siv dag zog, thiab lwm yam kev tawm tsam, thiab lwm yam kev tawm tsam tau ua rau muaj kev puas tsuaj hauv cheeb tsam).
3. Cov khoom hluav taws xob tsis xws luag thiab tswj
Txawm hais tias muaj kev loj hlob ntawm cov txheej txheem, tsis zoo me me tseem yuav tshwm sim vim yog kev tswj cov txheej txheem tsis raug cai. Txais yuav tsum tau txiav txim raws li daim ntawv thov cov xwm txheej:
Me tsis xws luag:
Cov Zinc Nodules Hauv Zos (Zinc Supup): Feem ntau tsis cuam tshuam kev tiv thaiv thiab tuaj yeem muab tshem tawm nrog kev ua tiav tom ntej;
Cov khawb me me lossis cov pob khaus: yog tias lub substrate tsis raug, cov txheej zinc, txheej zinc tseem muaj kev tiv thaiv;
Kev sib txawv: cov xim xim me muaj kev sib txawv tshwm sim los ntawm qhov sib txawv hauv cov nqi txias tsis muaj kev cuam tshuam ua haujlwm. Kev tsis xws luag loj kom tsis txhob:
Excosposed zinc: lub substrate tsis duav los ntawm zinc txheej, cia nws kom xeb ncaj qha, uas ua rau cov khoom tsis xws luag.
Zinc Detachment: Qhov no yog vim tsis zoo substrate pretreatment (piv txwv li, tsis tiav oxide nplai tshem tawm), ua rau muaj kev tiv thaiv txom nyem thiab kev tiv thaiv tsis zoo.
Thaj chaw loj ntawm cov dub lossis xeb: qhov no yuav tshwm sim los ntawm kev ua kom muaj kev cog qoob loo thiab tsis ua tiav cov txheej zinc, ua rau kev ua kom huv si ntawm cov txheej zinc. Kev Cia Cov Neeg Yuav Tsum Cia Yuav Tsum Tau Tswj.
4. Post {{- kev kho mob los txhim kho qhov chaw zoo
Txhawm rau txhim kho cov tsos lossis txhim kho corrosion tsis kam, s235jr galvanized cov khoom lag luam feem ntau yauv- kev kho:
Passivation: Kev kho nrog Chromate (ib txwm muaj) lossis chromium - Pub dawb passive Commic Form ua lub passive zaj duab xis nyob rau ntawm zinc nto. Qhov no txhim kho cov ntiv tes ua kom zoo thiab tiv thaiv kom muaj xeb dawb (thaum tseem tsim cov txheej txheem bluish hauv thaj chaw npau taws (nyob ntawm hom passivator).
Painting los yog phosphating: rau cov tsos ntxiv (piv txwv li, cov txheej txheej xim), tha xim tuaj yeem siv tau ntawm cov txheej zinc. Lub Zinc Txheej Kev Ua Haujlwm thiab Adhesion pab txhawb adhesion, muab ob qho kev tiv thaiv corrosion thiab zoo nkauj} Cov qauv zoo nkauj
Qhov chaw zoo ntawm s235jr galvanized cov khoom feem ntau ua raws li cov qauv galvanizing, xws li:
En 10346 (Kub Kub - dip galvanized steel ntawv (piv txwv li qhov loj me rau ploj galvanizing thiab zinc nodules);
ISO 1461 (Kev ua haujlwm ua rau kub- dip galvanized txheej ntawm cov khoom siv hlau thiab steel, zoo nkauj, thiab cov tsos ntawm txheej.
Lub ntsiab
Cov khoom lag luam zoo ntawm S235jr Galvanized cov khoom yog nruab ib ncig ntawm ** "Kev tiv thaiv, thiab cov kev siv hauv chaw nyob thiab cov txheej txheem sab nraud thiab sab nraum zoov. Thaum nws cov tsos tsis tiav siab dua - precision zoo nkauj zoo (piv txwv li daim iav ua kom tiav), cov kev kho kom yooj yim tuaj yeem tswj hwm los ntawm kev kho kev tu tsiaj lossis kev kho mob. Me me deg tsis xws luag feem ntau tsis cuam tshuam rau cov tub ntxhais ua haujlwm tiv taus. Rau cov ntawv thov yuav tsum muaj cov kev yuav tsum muaj zog (xws li cov tsev nyob), yuav ua tiav cov tsev), tuaj yeem ua tiav tau los ntawm kev ua kom zoo dua los ntawm kev ua kom zoo dua los ntawm kev ua kom zoo dua los ntawm kev ua kom zoo dua los ntawm kev ua kom huv lossis ncej} kev ua.
