galvanized koyilo processing

Kufotokozera Kwachidule:

Galvanizing amatanthauza pamwamba mankhwala luso plating wosanjikiza nthaka pamwamba zitsulo, aloyi kapena zipangizo kukongola ndi kupewa dzimbiri.Njira yaikulu ndi kutentha galvanizing.

Zinc imasungunuka mosavuta mu asidi ndi alkali, motero imatchedwa chitsulo cha amphoteric.Zinc sizisintha mumpweya wowuma.Mu mpweya wonyowa, filimu yowuma ya zinki carbonate idzapangidwa pamwamba pa nthaka.M'mlengalenga munali sulfure dioxide, hydrogen sulfide ndi m'nyanja m'mlengalenga, dzimbiri kukana nthaka ndi osauka, makamaka mu mlengalenga munali organic asidi pa kutentha ndi chinyezi, ndi nthaka ❖ kuyanika ndi zosavuta dzimbiri.Mphamvu ya elekitirodi ya zinki ndi -0.76v.Kwa gawo lapansi lachitsulo, zokutira zinki ndi za anodic zokutira.Amagwiritsidwa ntchito makamaka poletsa dzimbiri lachitsulo.Ntchito yake yoteteza imagwirizana kwambiri ndi makulidwe a zokutira.Zoteteza ndi zokongoletsera za zokutira za zinc zitha kusinthidwa bwino pambuyo pa passivation, utoto kapena kupaka ndi woteteza kuwala.
