Electric galvanized:
Karfe yana da sauƙin tsatsa a cikin iska, ruwa ko ƙasa, ko ma ya lalace gaba ɗaya.Asarar karfe na shekara-shekara saboda lalata yana yin lissafin kusan 1/10 na duk kayan aikin karfe.Bugu da ƙari, don ba da saman kayan ƙarfe da sassan aiki na musamman, yayin da suke ba su bayyanar kayan ado, ana bi da su ta hanyar electro-galvanizing.
① Ka'ida:
Tun da zinc ba shi da sauƙi a bambanta a cikin iska mai bushe, a cikin iska mai laushi, saman zai iya haifar da fim din nau'in nau'in carbonate mai yawa, wanda zai iya kare ciki yadda ya kamata ba lalata ba.
② Halayen ayyuka:
1. Tushen zinc yana da kauri, tare da lu'ulu'u masu kyau, daidaituwa kuma babu porosity, da juriya mai kyau;
2. Tushen zinc da aka samu ta hanyar lantarki yana da tsabta mai tsabta, kuma yana lalata sannu a hankali a cikin hazo na acid, alkali, da dai sauransu, kuma yana iya kare kariya daga karfe;
3. Tushen zinc yana wucewa ta hanyar chromic acid don samar da fari, mai launi, kore na soja, da dai sauransu, wanda yake da kyau da kayan ado;
4. Saboda rufin zinc yana da ductility mai kyau, ana iya kafa shi ta hanyar sanyi mai sanyi, mirgina, lankwasawa, da dai sauransu ba tare da lalata murfin ba.

Ⅰ.Bayani:
A cikin hanyar shafi daban-daban matrix karfe mai kariya, tsoma zafi yana da kyau sosai.Yana cikin yanayin da zinc ya zama ruwa, bayan ingantaccen ilimin kimiyyar lissafi, sinadarai, ba kawai tulin tulin tutiya mai kauri ba kawai a kan karfe ba, har ma da zinc-ferrous Layer.Wannan plating hanya ba kawai yana da lalata juriya halayyar lantarki galvanization, amma kuma saboda wani tutiya baƙin ƙarfe gami Layer.Har ila yau, yana da ƙarfin juriya ga electroplated zinc.Sabili da haka, wannan hanyar plating ya dace musamman don yanayin lalata mai ƙarfi kamar nau'in acid mai ƙarfi, hazo na alkaline.
Ⅱ.Ka'ida:
Zafin-tsoma galvanized Layer shine zinc a cikin ruwan zafi mai zafi, kuma an kafa shi ta matakai uku:
1. An narkar da saman tushen ƙarfe ta hanyar maganin zinc don samar da lokaci na zinc-ferrous;
2. Zinc ions a cikin gami Layer an kara yaduwa zuwa ga substrate don samar da tutiya baƙin ƙarfe intercollation Layer;
3. an rufe saman alloy Layer a cikin tukwane na zinc.
Ⅲ.Halayen ayyuka:
(1) Yana da kauri mai ƙaƙƙarfan tulin tulin tutiya mai ƙyalƙyali akan saman ƙarfen, wanda ke nisantar tuntuɓar matrix ɗin ƙarfe daga duk wani bayani na lalata don kare matrix ɗin ƙarfe daga lalata.A cikin yanayi na gabaɗaya, saman tudun zinc yana samar da wani ɗan ƙaramin bakin ciki na bakin ciki da kusancin zinc oxide Layer, wanda ke da wahalar narkewa cikin ruwa, don haka matrix ɗin ƙarfe yana taka wani tasiri na kariya.
(2) Tare da baƙin ƙarfe-zinc gami Layer, haɗe tare da m, a cikin marine gishiri humex yanayi da masana'antu yanayi nuna musamman lalata juriya;
(3) Tun da haɗin gwiwa yana da ƙarfi, zinc-iron yana solubilized, yana da ƙarfin juriya;
(4) Tun da zinc yana da ductility mai kyau, ƙirar alloy yana amintacce a haɗe zuwa ƙungiyar ƙarfe, don haka sassa masu zafi za su iya zama masu sanyi, birgima, goge, lankwasa, da makamantansu ba tare da lalata murfin ba;
(5) Bayan zafi galvanization na karfe finisse, shi ne daidai da annealing magani, wanda zai iya yadda ya kamata inganta inji Properties na karfe matrix, kawar da danniya na karfe gyare-gyaren waldi, wanda shi ne m ga juya karfe tsarin memba.
(6) Fuskar guntu bayan zazzafan galvanization yana da haske da kyau.
(7) Tsaftataccen tutiya Layer shine mafi filastik-roba-plated galvanized Layer a cikin zafi galvanized, wanda yake kusa da tsarkin zinc, ductility, don haka yana da sassauƙa.
Ⅳ.Iyakar aikace-aikace:
Aikace-aikace na zafi-tsoma ghanelyly ci gaban masana'antu da aikin gona.Don haka, kayayyakin gared mai zafi na masana'antu ne (kamar kayan aikin sinadarai, sarrafa mai, binciken ruwa, tsarin ƙarfe, isar da wutar lantarki, ginin jirgin ruwa, da sauransu), aikin gona (kamar: yayyafawa), gine-gine (kamar isar da ruwa da iskar gas). waya kafa Tube, scaffolding, gida, da dai sauransu), gada, sufuri, da dai sauransu an yi amfani da a yawan 'yan shekarun nan.
Tun da zafi-tsoma galvanized kayayyakin da kyau bayyanar, da kyau lalata juriya yi, da aikace-aikace kewayon ƙara fadi.
