Kub-dip galvanizingtxheej tsis zoo
1. Tsaus txheej
Nws yog nyob rau hauv patchy los yog reticular duab. Cov txheej hauv qhov grey thiab tsaus yog tag nrho Zn-Fe alloy. Cov txheej steel hlau uas muaj li ntawm 0.1% thiab ntau dua 0.3% silicon hlob sai heev. Ua ntej dej txias, txheej txheej alloy tau loj hlob mus rau saum npoo ntawm zinc txheej thiab poob nws cov xim hlau. Cov tsos ntawm grey txheej yog dab tuag, tab sis nws tsis muaj kev cuam tshuam rau lub txheej tiv thaiv atmospheric corrosion.
2. plating ploj
Cov xim seem, roj, oxide nplai, vuam slag thiab xeb qhov chaw uas tsis tuaj yeem raug tshem tawm los ntawm cov khoom siv li qub, lossis cov txheej txheem sib xyaw, cov khoom tsis yog xim hlau, thiab lwm yam, thaum txoj kab uas hla tsawg dua 2 hli, yuav tsis cuam tshuam rau corrosion kuj. Qhov luaj li cas ntawm thaj chaw tso cai rau kev kho, qhov kev faib ua feem ntawm tag nrho cheeb tsam thiab txoj kev kho yog ua raws li cov qauv ntawm cov khoom.
3. Plua plav daig ntawm qhov chaw
Cov particle zinc protrusions muaj cov khoom ntawm zinc-coated zinc slag FeZn13 (muaj 6% Fe), uas tsis cuam tshuam rau corrosion kuj.
4. Oxide zaj duab xis cim
Phenomenon: me ntsis oxide zaj duab xis cim rau ntawm qhov chaw ntawm plated.
Ua rau: tsis muaj txhuas; nres thaum lub sij hawm nqa ntawm plated qhov chaw los yog txoj kev tsis zoo ntawm kev tshem cov zinc plua plav.
Kev ntsuas kev kho mob: Tsis tas yuav tsum muaj kev kho mob, tab sis nws yuav tsum zam los ntawm kev kho cov tshuaj zinc thiab tshem tawm cov plua plav kom raug.
5. dawb xeb
Phenomenon: Plated qhov chaw tsim ib tug loj npaum li cas ntawm dawb corrosion khoom vim tsis raug stacking los yog cia tej yam kev mob.
Ua rau: Nyob rau hauv ib qho chaw ntub nrog huab cua tsis zoo, cov khoom siv plated tshiab tau ntim ua ntej yuav qhuav.
Yifa khoom: daim hlau, lub kaum sab xis steel, yeeb nkab fittings, thiab lwm yam.
Kev ntsuas kev kho mob: Qhov saum npoo ntawm cov khoom plated yuav tsum huv thiab tsis muaj dej noo thiab lwm yam khoom seem, thiab yuav tsum muab cia rau hauv qhov chaw qhuav thiab qhov cua. Cov khoom ntim yuav tsum tsis txhob sib cuag nrog hauv av, thiab tawm qhov sib txawv ntawm qhov chaw.
6. Dai zinc
Phenomenon: Zinc lossis zinc cov qog dai ntawm tus Tsov tus tw ntawm lub workpiece.
Yog vim li cas: Lub kaum sab xis ntawm cov hlau plated tsis txaus, lub lifting ceev ceev heev, qhov tsis xws luag yog tsis khawb nyob rau hauv lub sij hawm thaum lub plated seem tawm ntawm lub lauj kaub, los yog cov qauv peb-dimensional yog ib qho nyuaj rau tshem tawm.
Kev ntsuas kev kho mob: cov ntaub ntawv, grind thiab trim.
