Hot-kuviika galvanizing, ndi pa kutentha zinki ingots kusungunuka, kuikidwa mu zinthu wothandiza, ndiye dongosolo zitsulo kumizidwa mu nthaka plating kusamba, kuti zitsulo membala Ufumuyo wosanjikiza pa nthaka wosanjikiza.The otentha kanasonkhezereka ubwino zimadalira wosunga mphamvu, ndi bwino adhesion ndi kuuma kanasonkhezereka wosanjikiza.

Cold galvanizing ndi nthaka mchere njira ndi electrolysis, kuti plating pa ❖ kuyanika, ambiri, amene alibe Kutentha, kuchuluka kwa nthaka kawirikawiri anakumana chinyezi chilengedwe n'zosavuta kugwa.Kuzizira galvanizing mankhwala, basi padziko burashi wosanjikiza nthaka, nthaka ❖ kuyanika mosavuta kugwa ntchito yotentha-kuviika kanasonkhezereka yomanga.

Njira ya kutentha-kuviika galvanizing ndi ozizira galvanizing

Hot kuviika kanasonkhezereka kumizidwa mu madzi nthaka kusungunuka workpiece degreasing, pickling, kuviika, kuyanika nthawi ina ndi kuika patsogolo.

Cold galvanizing, amatchedwanso electro-galvanized, ndi ntchito electrolysis chipangizo workpiece mu zikuchokera njira mchere nthaka, pambuyo degreasing, pickling, ndi kulumikiza zoipa elekitirodi electrolytic chipangizo;Zinc mbale anaika mbali ina ya workpiece chikugwirizana mu electrolytic chipangizo ndi elekitirodi zabwino, mphamvu ndi anatembenukira, panopa kuchokera elekitirodi zabwino kwa kayendedwe negative directional, izo waikamo pa workpiece ndi wosanjikiza nthaka. .

Kuwoneka kwa kutentha kwa dip galvanizing ndi kuzizira kozizira

Cold galvanizing amawoneka yosalala, yowala, mtundu passivation ndondomeko plating wosanjikiza ndi wachikasu wobiriwira mu mtundu, anali zokongola.Plating wosanjikiza anali bluish-woyera kapena woyera ndi njira yoyera passivation anali wobiriwira, woyera ❖ kuyanika njira passivation ndi dzuwa anali ofunika Colorful ngodya.Mbali zovuta za m'mphepete mwazitsulo zomwe zimakhala ndi "kuwotcha kwamagetsi" kuchokera kumdima, zigawo za zinc wosanjikiza.Malo a ngodya ya Yin ndi osavuta kupanga malo otuwa omwe alipo pano komanso malo a zinc ndi ochepa.The workpiece wonse zinc chotupa, caking chodabwitsa.

Hot kuviika kanasonkhezereka kuyang'ana pang'ono akhakula poyerekeza ndi elekitiroti kanasonkhezereka, silvery woyera, kuyang'ana sachedwa ndondomeko waterlines ndi madontho ochepa cha chotupa ndi zoonekeratu, makamaka kumapeto kwa workpiece.Hot kuviika kanasonkhezereka nthaka wosanjikiza kuposa kangapo wa elekitiro-galvanized wandiweyani dzimbiri chitetezo ndi kangapo kuti elekitiro-galvanized.
