Kuv yuav tsum xyuam xim rau dab tsi thaum yuav Zn-Al-Mg photovoltaic brackets?
Apr 19, 2022
Zinc-aluminium-magnesium yog cov hlau alloy, uas yog hais txog cov ntawv hlau electroplated nrog ib qho nyiaj ntawm Al thiab Mg ntxiv rau cov txheej txheem kub-dip galvanized. Nws yog cov hlau alloy uas muaj cov khoom zoo heev. Galvanized aluminium magnesium photovoltaic kev them nyiaj yug muaj cov yam ntxwv hauv qab no:
1. Kev ua haujlwm yooj yim, galvanized aluminium-magnesium photovoltaic bracket, ncaj txiav thiab siv;
Txheej txheem kub dip galvanizing txheej txheem: workpiece → degreasing → dej ntxuav → pickling → dej ntxuav → immersion nyob rau hauv auxiliary electroplating hnyav → ziab thiab preheating → kub dip galvanizing → xov → txias → passivation → yaug → ziab → tshuaj xyuas. Yog tias kev ua haujlwm ntawm cov txheej txheem yav dhau los tsis zoo, nws yuav ua rau muaj kev cuam tshuam tsis zoo nyob rau hauv cov txheej txheem tom ntej, thiab ua rau cov nqi khiav lag luam zoo heev, lossis ua rau cov khoom tsis zoo kub dip txheej ntawm cov khoom galvanized.
Yog hais tias qhov pretreatment tsis zoo, cov zinc molten yuav tsis ua rau tag nrho cov hlau thiab tsim cov qauv zoo tshaj plaws galvanized zaj duab xis. Yog tias tom kawg tsis tau ua haujlwm zoo, cov tsos ntawm cov yeeb yaj kiab galvanized yuav puas thiab cov khoom lag luam yuav raug txo. Cov tsoos kub-dip galvanizing txiav yuav tsum tau galvanizing, kho xim, npaj nto, thiab rov qab logistics nyob rau hauv nruab nrab, thiab cov txheej txheem yog cumbersome. Piv nrog rau qhov no, kev txiav ncaj qha thiab siv cov zinc-aluminium-magnesium-coated stents yuav tsum tsis muaj kev rov ua dua thiab yog qhov hnyav thiab zoo nkauj.
Yog li ntawd, piv nrog cov txheej txheem ib txwm muaj, zinc-aluminium-magnesium txheej yuav txo tau ntau lub sijhawm, cov neeg ua haujlwm, cov khoom siv thiab cov nyiaj txiag, thiab cov nqi tsim nyog!
2. Tsis siv neeg kho, zinc, aluminium thiab magnesium yuav tau kho cov txheej txheem ntawm kev txiav, stamping thiab profiles;
Yog vim li cas yog tias txheej txheej dhau los ua tshuaj lom neeg hauv huab cua. Magnesium ions ua ntej tsim magnesium hydroxide, thiab tom qab ntawd magnesium hydroxide absorbs carbon dioxide los ua magnesium carbonate. Cov tshuaj no muaj cov nyhuv buffering ntawm tus nqi pH thiab txo qhov kev sib cais ntawm zinc hauv dej. anode cheeb tsam thiab inhibit oxidation.
Qhov tsim ntawm zinc thiab magnesium txhawb nqa kev tsim cov khoom siv tuab thiab txo qhov kev sib txawv ntawm cov pa oxygen, yog li txo qhov txo tus pa hauv cheeb tsam cathode. Ntawm lawv, magnesium ions thiab oxygen ions tau txais cov tshuaj tiv thaiv redox, thiab "dawb xeb" txheej tiv thaiv tsim ntawm stent paub txog kev kho tsis siv neeg.
Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm kev txiav, xuas nrig ntaus thiab ntoo khaub lig-section uas puas lub txheej, magnesium ion redox cov tshuaj tiv thaiv yuav tsiv mus nyob rau qhov puas ntawm cov txheej, tsim ib tug ntom magnesium carbonate tiv thaiv zaj duab xis, thiab qhov ceev yuav tsis tuag! kho.
3. Corrosion kuj, corrosion kuj ntawm zinc-aluminium-magnesium yog 5-10 zaus ntawm cov tsoos kub-dip galvanizing;
Cov tsoos kub-dip galvanized txheej txheej muaj ntau zaus thiab xeb liab ntawm qhov chaw raug thaum ntxov ntawm corrosion. Nrog rau lub sijhawm ntev ntawm corrosion, thaj tsam ntawm xeb liab yuav nce; zaj duab xis "dawb xeb" yog ib txheej tiv thaiv ntom tsim ntawm stent, uas tuaj yeem ua tiav cov nyhuv kho tus kheej.
Raws li qhov tshwm sim, zinc, aluminium thiab magnesium txheej tuaj yeem ua tau zoo dua corrosion kuj thiab tsawg txheej adhesion piv rau cov khoom siv, txuag cov khoom siv thiab sijhawm. Nws muaj kev tiv thaiv zoo dua rau kev txiav ntug ntawm cov hlau phaj, qhov chaw welded thiab qhov chaw uas cov txheej yog puas vim yog deformation loj.
