Yuav ua li cas xaiv txoj cai roj nplua los tiv thaiv lub galvanized txheej thaum stamping?
Hauv cov txheej txheem stamping ntawm Spcc- gi (kub} Cov ntsiab cai xaiv thiab hom muaj raws li hauv qab no:
1. Cov ntsiab cai tseem ceeb rau cov roj nplua nyeem xaiv
Tshuaj sib xyaw ua ke:
Lub galvanized txheej (zinc) yog yooj yim corroded los ntawm cov tshuaj acidic thiab alkaline. Yog li ntawd, cov roj nplua nyeem yuav tsum yog nruab nrab lossis me ntsis alkaline (pH 6.5-8.5). Nws yuav tsum tsis muaj muaj cov kua qaub muaj zog (xws li hydrochloric acid thiab sulfuric acid), xws li sodium hydroxide) los tiv thaiv cov txheej los ntawm corroding, tig nws dawb, thiab tev. Lubrication kev ua tau zoo txuam:
Xaiv covrication siv raws li cov nyom ntawm cov txheej txheem stamping (ntiav, sib sib zog nqus, lossis kos duab):
Canow stamping / Yooj yim tsim: Moderate Pluav muaj txaus kom tsis txhob muaj cov dej khov nplua nuj uas tsis huv.
Kev sib sib zog nqus duab / cov teeb meem nyuaj: siab heev siab tiv taus ntawm kev tuag thiab cov txheej txheem, uas tuaj yeem ua rau txheej thiab siab {{{} kev yi emosion.
Haum rau cov txheej txheem tom ntej:
Yog tias vuam lossis tha xim yog xav tau tom qab stamping, cov roj nplua nyeem yuav tsum:
Yooj yim tshem tawm ua ntej vuam (tsis muaj seem uas cuam tshuam rau kev ua haujlwm);
Tshem tawm los ntawm kev ntxuav cov tshuaj tiv thaiv ua ntej kev pleev xim (tsis cuam tshuam rau ntawm txheej txheej adhesion).
Stability:
Resistant rau delamination thiab detheration dhau ntev -} {1} corrosive rau cov kua roj (xeb).
