1.How tsis tiav kev ntxuav tu nws tus kheej?
Cov Txheej Txheem Tseem Ceeb: Degreasing (alkaline / electrolytic huv) siab, kub, thiab sijhawm; acid confentration thiab ceev rau pickling (yog tias yuav tsum tau).
Teeb Meem Teeb Meem:
Residual dov roj, plua plav plua plav, lossis roj stains ntawm lub substrate saum ua rau kev siv roj carbonancy thaum lub sij hawm anealing, sib sau "roj pob." Qhov no txwv tsis pub zinc los ntawm adhering thaum Galvanizing, uas ua rau plating txeej.
Oxide nplai tsis tau tshem tawm tag nrho, tsis muaj zog cov nyiaj sib khi ntawm cov oxide nplai thiab cov substrate tom qab anealing. Thaum Galvanizing, Zinc Slag cov ntaub ntawv raws li cov zinc daws teeb, ua rau zinc pattratling tsis xws luag.
2. Qhov teeb meem ntawm cov qauv ua tsis zoo substrate manifest nws tus kheej?
Cov Txheej Txheem Tseem Ceeb: Flnessness ntawm cov khaub ncaws txias-rolled (piv txwv li, laim ntoom, laim ntoom los yog camber).
Teeb Meem Teeb Meem: Ntug los yog Center Wavy Strips Ua Rau Tsis Muaj Cua Sov Thaum nkag mus rau Innaling Rauv, uas tuaj yeem yooj yim ua rau muaj kev sib xyaw ua ke hauv cheeb tsam.
Kev txom nyem sawb cov qauv ua rau muaj kev cuam tshuam tsis sib xws thaum lub sijhawm ua haujlwm ntawm cov zeb, tsis sib haum ntawm cov cua tshuab, thiab tsis sib xws.
3.Qhov teeb meem yuav tshwm sim los ntawm kev tswj hwm qhov kub ntawm annealing kub / sijhawm?
Tsawg heev ntawm qhov kub lossis kub tsis txaus: kev ntxhov siab tsis txaus ntawm substrate tsis tau muab tshem tawm tag nrho, ua rau kev ua tiav (xws li stamping) nquag mus tawg.
Siab dhau qhov kub thiab txias lossis ntau dua cov nplej uas muaj ntau yam kom txo qis cov khoom siv tau yooj yim rau saum npoo (yog tias cov huab cua tsis zoo).
4.Qhov teeb meem txawv txav annealing huab cua zoo li cas?
Cov Txheej Txheem Tseem Ceeb: Yuav tsum muaj ntau dua los yog sib npaug ntawm 99.9%), huab cua kom tsis txhob muaj oxidation), yuav tsum tsawg dua lossis sib npaug rau 10 ppm).
Teeb Meem Teeb Meem:
Ntau dhau dew point (ntau dhau noo) lossis ntau dhau cov pa oxygen: oxidation cov ntaub ntawv ib feo / fe₃o₄ zaj duab xis nyob rau sab nraud. Thaum lub sijhawm Zin plating, cov zinc tsis muaj peev xwm nkag mus rau thaj chaw oxidized, ua rau cov plating hle plaub hau lossis zinc txheej shedding.
Lub zog hydrogen Tsis txaus: lub zog txo qis yog tsis muaj zog, tsis tuaj yeem tshem tawm LACE oxide nplai seem, cuam tshuam rau cov nplaum ntawm zinc txheej.
5.Qhov teeb meem dab tsi tuaj yeem hle kev sib cav lossis kev nyuaj siab hloov ua?
Cov Txheej Txheem Tseem Ceeb: kev ua kom sib haum xeeb ntawm cov phau ntawv qhia cov txiv ntoo hauv kev siv hluav taws xob hauv lub cub tawg thiab nro tswj qhov.
Teeb Meem Teeb Meem:
Sawb dispiation ua rau ntug ntawm sawb los txhuam tiv thaiv cov cua sov phab ntsa, ua rau "ntug hlawv" lossis khawb.
Kev nro ntau dhau ua rau cov sawb rau deform lossis txawm so. Kev sib tw ntau dhau ua rau cov sawb rau sag rau sag, uas nyob rau hauv kev sib cuag tsis ncaj nrog cov chais thiab nquag rau cov menyuam cim.
