Game da yadda tsoma bututun ƙarfe na galvanized, aiwatar da galvanizing mai zafi tsoma yana haifar da haɗin gwiwar ƙarfe tsakanin tutiya da ƙarfe tare da jerin gwanayen ƙarfe-zinc na musamman. Layin galvanizing mai zafi na yau da kullun yana aiki kamar haka:
1. Ana tsabtace karfe ta amfani da maganin caustic. Wannan yana cire mai/koko, datti, da fenti.
2. Ana wanke maganin tsaftacewa na caustic.
3. An tsince karfe a cikin maganin acidic don cire ma'aunin niƙa.
4. Ana wanke maganin pickling.
5. A juyi, sau da yawa zinc ammonium chloride ana amfani da shi zuwa karfe don hana iskar shaka na tsabtataccen farfajiya a kan fallasa zuwa iska. Ana barin juyi ya bushe akan karfe kuma yana taimakawa wajen aiwatar da jikakken tutiya mai ruwa da manne da karfe.
6. Ana tsoma karfen a cikin ruwan wanka na zinc da aka narkar da shi kuma a ajiye shi a can har sai zafin jiki na karfe yayi daidai da na wanka.
7. An sanyaya karfe a cikin tanki mai kashewa don rage yawan zafin jiki kuma ya hana halayen da ba a so na sabon suturar da aka kafa tare da yanayi.
A fasaha, galvanization wani tsari ne na shafa ƙarfe da ƙarfe tare da Layer na zinc ta hanyar nutsar da ƙarfe a cikin wanka na zurfafan zinc a zafin jiki na kusan 840 ° F (449 ° C). Lokacin da aka fallasa shi zuwa sararin samaniya, zinc mai tsabta (Zn) yana amsawa tare da oxygen (O2) don samar da zinc oxide (ZnO), wanda ya kara amsawa da carbon dioxide (CO2) don samar da zinc carbonate (ZnCO3), yawanci launin toka, mai ƙarfi sosai. kayan da ke kare karfen da ke ƙasa daga ƙarin lalacewa a yanayi da yawa. Gabaɗaya, bututun galvanized mai zafi yana da farashin bututun ƙarfe mafi girma fiye da sauran nau'ikan bututun da ake amfani da su saboda tsadar masana'anta a kasuwa.
Don aikace-aikacen aikace-aikacen, kamar sauran tsarin kariya na lalata, galvanizing galibi yana kare samfuran ƙarfe ta hanyar aiki azaman shinge tsakanin bututun ƙarfe da yanayi. Duk da haka, zinc ya fi ƙarfin lantarki idan aka kwatanta da karfe. Wannan siffa ce ta musamman don galvanizing. Musamman, lokacin da murfin galvanized ya lalace kuma samfurin karfe yana nunawa ga yanayi, zinc zai iya ci gaba da kare karfe ta hanyar lalata galvanic. Bugu da ƙari kuma, idan wannan shafi ya faru da za a karce ko gouged, zinc ta sakandare tsaro da ake kira don kare karfe ta galvanic mataki. A cikin injin niƙa, ana sarrafa kauri na zinc ta tsawon lokacin da kowane sashi ya nutse a cikin narkakken zinc bath da kuma saurin cire shi. Kalmar “dipping biyu” tana nufin sassan da suka yi girma da yawa don su dace da kettle na galvanizing kuma dole ne a tsoma ƙarshensu lokaci guda. Ba ya nufin ƙarin kauri.
