A lokacin watsa wutar lantarki, hasumiya na ƙarfe abu ne mai mahimmanci. Lokacin samar da samfuran ƙarfe na hasumiya na baƙin ƙarfe, ana ɗaukar tsarin samar da galvanizing mai zafi gabaɗaya akan saman don kare saman samfuran ƙarfe daga lalatar iska ta waje da wurare daban-daban. Yin amfani da tsarin galvanizing mai zafi mai zafi zai iya cimma sakamako mai kyau na lalata. Tare da mafi girman buƙatun watsa wutar lantarki, abubuwan da ake buƙata don tsarin samar da samfuran ƙarfe na galvanized kuma sun fi girma.
(1) Asalin ka'idar zafi tsoma galvanizing
Hot tsoma galvanizing, kuma aka sani da zafi tsoma galvanizing, yana daya daga cikin mafi ingancin shafi hanyoyin don kare karfe substrate. A cikin tutiya ruwa, bayan karfe workpiece ya jure jiki da kuma sinadaran magani, da karfe workpiece ne immersed a zurfafa tutiya da zazzabi na 440 ℃ ~ 465 ℃ ko mafi girma ga magani. Ƙarfe na ƙarfe yana amsawa tare da zurfafan tutiya don samar da Layer na Zinare na Zinariya da tsantsa mai tsaftataccen tutiya kuma ya rufe gabaɗayan saman aikin ƙarfe. Fuskar galvanized yana da wasu tauri, yana iya jure babban juzu'i da tasiri, kuma yana da kyakkyawar haɗuwa tare da matrix.
Wannan hanyar plating ba kawai yana da juriyar lalata na galvanizing ba, har ma yana da Layer na Zn Fe gami. Hakanan yana da juriya mai ƙarfi wanda ba za a iya kwatanta shi da galvanizing ba. Saboda haka, wannan hanyar plating ya dace musamman ga wurare daban-daban masu ƙarfi masu lalata kamar su acid mai ƙarfi, alkali da hazo.
(2) Halayen ayyuka na hot tsoma galvanizing
Yana da kauri da ƙaƙƙarfan tsaftataccen tulin tutiya a saman saman ƙarfe, wanda zai iya guje wa tuntuɓar ma'aunin ƙarfe tare da duk wani bayani na lalata da kuma kare ƙwayar ƙarfe daga lalata. A cikin yanayi na gabaɗaya, an samar da siriri kuma mai yawa zinc oxide Layer a saman tudun zinc, wanda ke da wahalar narkewa a cikin ruwa, don haka yana taka rawa wajen kare matrix na karfe. Idan zinc oxide da sauran abubuwan da ke cikin yanayi sun samar da gishirin zinc maras narkewa, tasirin anti-lalata ya fi dacewa.
Bayan galvanizing mai zafi-tsoma, ƙarfe yana da Layer alloy na Zn Fe, wanda yake ƙanƙanta kuma yana da juriya na musamman a cikin hazo gishirin ruwa da yanayin masana'antu. Saboda haɗin gwiwa mai ƙarfi, Zn Fe yana da ɓarna kuma yana da ƙarfi juriya. Saboda tutiya yana da kyau ductility da gami Layer aka da tabbaci a haɗe zuwa karfe substrate, da zafi-tsoma galvanized workpiece za a iya kafa ta sanyi punching, mirgina, waya zane, lankwasawa, da dai sauransu ba tare da žata tutiya shafi.
Bayan zafi galvanizing, da karfe workpiece ne daidai da wani annealing magani, wanda zai iya yadda ya kamata inganta inji Properties na karfe substrate, kawar da danniya na karfe workpiece a lokacin kafa da waldi, kuma shi ne m ga juya karfe workpiece.
A saman karfe workpiece bayan zafi galvanizing ne mai haske da kyau. Tushen tutiya mai tsafta shine mafi filastik tutiya Layer a cikin galvanizing mai zafi. Kaddarorinsa suna kama da tutiya mai tsabta, kuma yana da ductility, don haka yana da sassauƙa.
