Chizindikiritso cha electrogalvanized zitsulo kabati ndi otentha-kuviika kanasonkhezereka zitsulo kabati

M'mbuyomu, kusiyana pakati pa electrogalvanized zitsulo kabati ndi otentha-kuviika kanasonkhezereka zitsulo kabati makamaka anadalira kuyendera maganizo a zinki spangles. Zinc spangles zimatanthawuza maonekedwe a njere zomwe zimapangidwira pambuyo potulutsa zitsulo zotentha zoviikidwa mumphika watsopano ndipo nthaka yosanjikiza ya zinki imazizira ndi kulimba. Choncho, pamwamba pa kutentha kuviika kanasonkhezereka zitsulo kabati zambiri akhakula, ndi mmene nthaka spangles, pamene pamwamba pa electrogalvanized zitsulo kabati ndi yosalala. Komabe, ndi kusintha kwa umisiri watsopano, kutentha kuviika kanasonkhezereka zitsulo kabati alibenso makhalidwe mmene wamba nthaka spangles. Nthawi zina pamwamba pa kutentha-kuviika kanasonkhezereka zitsulo kabati ndi owala ndi kuwala kwambiri kuposa electrogalvanized zitsulo kabati. Nthawi zina, pamene kutentha-kuviika kanasonkhezereka zitsulo kabati ndi electrogalvanized zitsulo kabati aikidwa palimodzi, n'zovuta kusiyanitsa chimene ndi otentha-kuviika kanasonkhezereka zitsulo kabati ndi chomwe ndi electrogalvanized zitsulo kabati. Choncho, awiriwa sangasiyanitsidwe ndi maonekedwe pakali pano.

Palibe njira yozindikiritsira kusiyanitsa njira ziwirizi zopangira galvanizing ku China kapena ngakhale padziko lonse lapansi, kotero ndikofunikira kuphunzira njira yosiyanitsira awiriwa kuchokera muzu wazongopeka. Pezani kusiyana pakati pa ziwirizi kuchokera pa mfundo ya galvanizing
, ndi kuwasiyanitsa ndi kukhalapo kapena kusowa kwa Zn-Fe alloy wosanjikiza kwenikweni. Zikatsimikiziridwa, ziyenera kukhala zolondola. Mfundo yotentha-kuviika galvanizing ya zitsulo grating mankhwala ndi kumiza zitsulo mankhwala pambuyo kuyeretsa ndi kutsegula mu sungunuka zinki madzi, ndi mwa anachita ndi mayamwidwe pakati chitsulo ndi nthaka, ndi nthaka aloyi ❖ kuyanika ndi zomatira zabwino ndi yokutidwa pamwamba pa zitsulo grating mankhwala. Kapangidwe ka galvanizing layer yotentha ndi njira yopangira aloyi yachitsulo-zinc pakati pa matrix achitsulo ndi wosanjikiza wakunja wa zinc. Kumamatira kwake kolimba kumatsimikiziranso kukana kwake kwa dzimbiri. Kuchokera ku mawonekedwe a microscopic, amawonedwa ngati mawonekedwe a magawo awiri.
Mfundo electrogalvanizing zitsulo grating mankhwala ndi ntchito electrolysis kupanga yunifolomu, wandiweyani, ndi bwino Bonded zitsulo kapena aloyi mafunsidwe wosanjikiza pamwamba pa zitsulo kabati mbali zitsulo, ndi kupanga ❖ kuyanika pamwamba pa kabati zitsulo, kuti tikwaniritse ndondomeko kuteteza kabati zitsulo ku dzimbiri. Chifukwa chake, zokutira zama electro-galvanized ndi mtundu wa zokutira zomwe zimagwiritsa ntchito kayendedwe ka magetsi kuchokera ku electrode yabwino kupita ku electrode yoyipa. Zn2 + mu ma electrolyte nucleates, imakula ndikuyika pagawo lachitsulo lachitsulo pansi pa mphamvu yokhoza kupanga gulu lamalata. Munjira iyi, palibe njira yolumikizirana pakati pa zinki ndi chitsulo. Malinga ndi mawonekedwe a microscopic, ndithudi ndi wosanjikiza wa zinki.
Kwenikweni, galvanizing yotentha imakhala ndi chitsulo-zinki aloyi wosanjikiza ndi wosanjikiza wa zinki koyera, pamene electro-galvanizing ali kokha woyera zinki wosanjikiza. Kukhalapo kapena kusakhalapo kwa chitsulo-zinc alloy wosanjikiza mu zokutira ndiye maziko akulu ozindikiritsa njira yokutira. Metallographic njira ndi XRD njira makamaka ntchito kudziwa ❖ kuyanika kusiyanitsa electro-galvanizing ndi otentha-kuviika galvanizing.
