1.Superior Tsatsa Resistance
Babban burin galvanizing shine dakatar da tsatsa a cikin waƙoƙin sa - kuma anan ne ma'aunin zinc oxide akan karfen galvanized ya shigo. Ga yadda yake aiki: murfin zinc yana lalata da farko, yana ɗaukar bugun don haka karfen da ke ƙarƙashinsa ya daɗe. Idan ba tare da wannan garkuwar zinc ba, ƙarfe zai fi dacewa da tsatsa, kuma bayyanar da ruwan sama, zafi, ko wasu abubuwa na halitta zai gaggauta lalata.
2. Tsawon Rayuwa
Wannan tsawon rai yana fitowa kai tsaye daga murfin kariya. Bincike ya nuna cewa, a cikin yanayi na yau da kullun, ƙarfe na galvanized da ake amfani da shi a cikin saitunan masana'antu na iya ɗaukar tsawon shekaru 50. Ko da a cikin mahalli masu lalacewa sosai-tunanin wuraren da ruwa mai yawa ko danshi-zai iya ɗauka har tsawon shekaru 20 ko fiye.

Yawancin mutane sun yarda cewa galvanized karfe yana da kyan gani fiye da sauran kayan haɗin ƙarfe. Fuskokinsa yana ƙara yin haske da tsabta, yana ba shi kyan gani.
Inda Aka Yi Amfani da Karfe Galvanized
Ana iya amfani da matakai daban-daban don galvanizing:
2. Electro galvanizing
3. Zinc yaduwa
4. Karfe feshi
Hot-tsoma galvanized
A lokacin aikin galvanizing, ana nutsar da ƙarfe a cikin narkakken wankan zinc. Hot-tsoma galvanizing (HDG) ya ƙunshi matakai na asali guda uku: shirye-shiryen saman, galvanizing, da dubawa.
Shirye-shiryen Sama
A cikin tsarin shirye-shiryen saman, an aika da ƙarfe da aka riga aka yi don galvanizing kuma yana jurewa matakan tsaftacewa guda uku: raguwa, wanke acid, da jujjuyawa. Idan ba tare da wannan tsarin tsaftacewa ba, galvanizing ba zai iya ci gaba ba saboda zinc ba zai amsa da ƙarfe mara kyau ba.
Galvanizing
Bayan an gama shirye-shiryen saman, ana nutsar da ƙarfe a cikin zurfafan zinc 98% a 830 ° F. Wurin da aka nutsar da ƙarfe a cikin tukunyar ya kamata ya ba da damar iska ta tsere daga sifofin tubular ko wasu aljihu. Wannan kuma yana ba da damar zinc ta gudana ta cikin jikin karfe duka. Ta wannan hanyar, zinc yana shiga cikin hulɗa tare da dukan karfe. Iron da ke cikin karfe ya fara amsawa tare da zinc, yana samar da suturar tsaka-tsakin zinc-baƙin ƙarfe. A gefen waje, an ajiye murfin zinc mai tsabta.
Dubawa
Mataki na ƙarshe shine bincika sutura. Ana gudanar da bincike na gani don bincika duk wuraren da ba a rufe ba a jikin karfe, saboda rufin ba zai bi da karfe marar tsabta ba. Hakanan za'a iya amfani da ma'aunin kauri na maganadisu don tantance kauri.
2 Electro galvanizing
Electrogalvanized karfe ana yin shi ta hanyar tsarin lantarki. A cikin wannan tsari, ana nutsar da karfe a cikin wanka na zinc, kuma ana ratsa wutar lantarki ta cikinsa. Wannan tsari kuma ana kiransa da electroplating.
Kafin aikin electrogalvanizing, dole ne a tsaftace karfe. Anan, zinc yana aiki azaman anode don kare karfe. Don electrolysis, zinc sulfate ko zinc cyanide ana amfani dashi azaman electrolyte, yayin da cathode ke kare karfe daga lalata. Wannan electrolyte yana sa zinc ya kasance a kan saman karfe a matsayin sutura. Tsawon lokacin da karfe yana nutsewa a cikin wanka na zinc, daɗaɗɗen rufin ya zama.
Don haɓaka juriya na lalata, wasu suturar juyawa suna da tasiri sosai. Wannan tsari yana samar da ƙarin nau'in zinc da chromium hydroxides, wanda ke haifar da bayyanar shuɗi akan saman karfe.
3 Zuciyar Zinc
Plating na Zinc ya ƙunshi samar da suturar zinc a saman ƙarfe ko ƙarfe don hana lalata ƙarfe.
A cikin wannan tsari, ana sanya ƙarfe a cikin akwati da zinc, sannan a rufe shi kuma a yi zafi a ƙasa da wurin narkewa na zinc. Sakamakon wannan dauki shine samuwar sinadarin zinc-baƙin ƙarfe, tare da ƙaƙƙarfan Layer na tutiya mai tsafta wanda ke manne da saman ƙarfe kuma yana ba da juriya mai mahimmanci. Wannan shafi kuma yana sauƙaƙe mafi kyawun mannewar fenti a saman.
Don ƙananan abubuwa na ƙarfe, yin amfani da zinc shine hanya mafi kyau. Wannan tsari ya dace musamman don abubuwan ƙarfe waɗanda ba su da siffa ba bisa ka'ida ba, saboda Layer na waje yana iya bin tsarin karfen tushe cikin sauƙi.
4 Fesa Karfe
A cikin ƙarfe na fesa tutiya plating tsari, lantarki caje ko atomized narkakkar barbashi zinc a kan karfe surface. Ana aiwatar da wannan tsari ta hanyar amfani da bindigar feshi na hannu ko harshen wuta na musamman.
Kafin yin amfani da murfin zinc, duk wani gurɓataccen abu, kamar kayan da ba a so, mai, da tsatsa, dole ne a cire su. Bayan aikin tsaftacewa ya cika, ana fesa barbashin tutiya da aka narkar da su a kan ƙasa maras kyau, inda suke ƙarfafawa.
Wannan hanyar feshin ƙarfe na ƙarfe shine mafi dacewa don hana peeling da flaking, amma bai dace ba don samar da juriya mai mahimmanci.
Yaya tsawon lokacin da rufin zinc zai kasance?
Dangane da karko, yawanci ya dogara ne da kaurin murfin zinc, da kuma wasu abubuwa kamar nau'in muhalli, nau'in murfin zinc da aka yi amfani da shi, da ingancin fenti ko feshi. Girman murfin zinc, mafi tsayin rayuwa.
Hot-tsoma galvanizing vs. sanyi galvanizingRubutun galvanized mai zafi-tsoma gabaɗaya sun fi ɗorewa fiye da suturar galvanized mai sanyi saboda yawanci sun fi kauri kuma sun fi ƙarfi. Galvanizing mai zafi ya haɗa da nutsar da ƙarfe a cikin narkakkar zinc, yayin da a cikin hanyar galvanizing mai sanyi, ana fesa yadudduka ɗaya ko biyu ko a goge su.
Dangane da tsayin daka, suturar galvanized mai zafi mai zafi na iya wucewa sama da shekaru 50 ba tare da la’akari da yanayin muhalli ba. Sabanin haka, suturar galvanized mai sanyi-tsoma yawanci tana ɗaukar watanni kaɗan zuwa ƴan shekaru, ya danganta da kauri mai rufi.
Bugu da ƙari, a cikin mahalli masu ɓarna kamar saitunan masana'antu, za a iya iyakance tsawon rayuwar suturar zinc. Don haka, zaɓin kayan kwalliyar zinc masu inganci da kiyaye su na dogon lokaci yana da mahimmanci don haɓaka kariya daga lalata, lalacewa, da tsatsa.
