A na-akpọkwa galvanizing na-ekpo ọkụ nke efere ígwè.A na-agbaze ingot Zinc n'ebe okpomọkụ, a na-agbakwunyekwa ụfọdụ ihe enyemaka n'ime galvanizing na-ekpo ọkụ.A na-etinyezi akụkụ nke grid ígwè na tankị galvanizing na akwa galvanizing na-ejikọta na efere ígwè.Ike nke galvanizing na-ekpo ọkụ na-adabere na nguzogide corrosion ya, na adhesion na hardness nke galvanized mpempe akwụkwọ ka mma.Ọnụ ego nke galvanized ígwè efere mgbe galvanizing.Yabụ na nke a bụ ọnụọgụ zinc n'ozuzu ya.
Ngwakọta nke na-ekpo ọkụ itinye galvanizing oyi akwa bụ nke na-ekpo ọkụ itinye galvanizing oyi akwa, nke na-emi esịnede ígwè zinc alloy n'etiti ígwè matrix na elu dị ọcha zinc oyi akwa.The udi nke workpiece na-kpụrụ ígwè zinc alloy oyi akwa na-ekpo ọkụ itinye, nke mere na ígwè na dị ọcha zinc oyi akwa emetụ pụtara ìhè.Mgbe ígwè workpiece na-mikpu na a wụrụ zinc ngwọta, mbụ zinc na ígwè (ahụ) na-guzobere na interface.Nke a bụ kristal mejupụtara atọm zinc na ígwè siri ike.Mgbe atom ọla abụọ jikọtara ọnụ, ike ndọda dị n'etiti atọm dị obere.
Ya mere, mgbe zinc zuru ezu na agbaze siri ike, atom abụọ nke zinc na ígwè na-agbasasị ibe ha.Atọm zinc dị na matrix iron na-ebugharị n'ime lattice nke matrix ahụ, a na-eji nke nta nke nta mepụta ihe ndị ahụ ka ọ bụrụ alloys.Ngwakọta zinc nke ígwè na intermetallic compound FeZn13 na ngwọta zinc gbazere na ala nke mpempe akwụkwọ galvanized na-ekpo ọkụ nwere ike iji dị ka zinc slag.Igwe akwa zinc dị ọcha nke ihe ngwọta zinc leaching mejupụtara bụ kristal hexagonal.
Mgbe okpomọkụ na-agba ọsọ n'otu okpomọkụ ma na-echekwa otu okpomọkụ ahụ, ọnụ ọgụgụ nke ígwè gbazere abụghị otu.N'ihe dị ka 500, ọnwụ nke ígwè na-abawanye nke ọma na mgbakwunye nke okpomọkụ na mkpuchi.Ọ dị ala ma ọ bụ dị elu karịa 480 ~ 510c, na ọnwụ nke ígwè epitaxial na-adị nwayọọ, ọ na-esikwa ike ijide ogologo oge.Ya mere, onye ọ bụla ga-akpọ 480 ~ 510c mpaghara agbaze ọjọọ.
N'ime oke okpomọkụ a, ihe ngwọta zinc na-emebi nke ọma na workpiece na ite zinc, na ígwè ahụ na-efunahụ na 560 degrees Celsius iji gbakwunye n'ụzọ doro anya, na zinc ga-abụ ihe ntinye ígwè n'elu 660 degrees Celsius, zinc slag ga-agbakwunyere. ngwa ngwa, plating enweghị ike iji.Ya mere, electroplating a rụrụ na nso nke 430 ~ 450 degrees Celsius.
