The difference between galvanized bridge and hot-dip galvanized bridge

Firam ɗin gada mai galvanized:

Galvanized gada, kuma aka sani da gadar galvanized lantarki; Gabaɗaya ana fahimtar gadar galvanized gada mai zafi tsoma galvanized, a gaskiya, ba daidai ba ne, kamar galvanized tube, galvanized gada ya kasu kashi biyu, wato, sanyi galvanized (electric galvanized) da zafi tsoma galvanized (hot- tsoma galvanized). );

Ƙarfe da tsatsa cikin sauƙi a cikin iska, ruwa ko ƙasa, ko ma lalacewa gaba ɗaya. Asarar karfe na shekara-shekara da lalacewa ta haifar ya kai kusan kashi 1/10 na dukkan kayan aikin karfe. A gefe guda kuma, don yin samfuran ƙarfe da sassa suna da aiki na musamman a saman, kuma suna ba da siffar adonsa a lokaci guda, don haka gabaɗaya ana bi da shi ta hanyar galvanizing na lantarki.

1. Ka'ida:

Saboda zinc ba sauki canza a bushe iska, kuma a cikin m iska, da surface iya samar da wani sosai m asali zinc carbonate film, wannan fim iya yadda ya kamata kare ciki daga lalata. Kuma lokacin da rufin ya lalace saboda wasu dalilai kuma tushe na karfe bai yi girma ba, zinc da matrix na karfe suna samar da microbattery, don haka matrix na karfe ya zama cathode kuma ana kiyaye shi.

2. Halayen Aiki:

1) Rufin zinc yana da kauri, crystallization yana da kyau, uniform kuma babu pores, kuma juriya na lalata yana da kyau;

2) Tushen zinc da aka samu ta hanyar lantarki yana da tsabta kuma yana lalata sannu a hankali a cikin acid da alkali hazo, wanda zai iya kare matrix karfe yadda ya kamata;

3) Tutiya shafi kafa ta chromic acid passivation fari, launi, soja kore, kyau, yana da wani kayan ado;

4) Domin tutiya shafi yana da kyau ductility, zai iya zama sanyi blanking, mirgina, lankwasawa da sauran forming ba tare da žata da shafi.

3. Iyakar aikace-aikace:

Misali, kera injina, na'urorin lantarki, na'urori masu inganci, masana'antar sinadarai, masana'antar hasken wuta, sufuri, makamai, sararin samaniya, makamashin atomic da sauransu, suna da matukar muhimmanci a tattalin arzikin kasa.

Gada mai zafi-tsoma galvanized(Zincin gada mai zafi)

1, bayanin zinc tsoma zafi:

Hot tsoma tutiya daya daga cikin mafi kyau shafi hanyoyin don kare karfe substrate. Yana da a cikin ruwa jihar na tutiya, bayan quite hadaddun jiki da kuma sinadaran mataki, ba kawai a kan karfe plating thicker tsarki tutiya Layer, amma kuma samar da tutiya - baƙin ƙarfe gami Layer. Wannan plating hanya ba kawai yana da halaye na lalata juriya na galvanizing, amma kuma yana da tutiya-baƙin ƙarfe gami Layer. Hakanan yana da juriya mai ƙarfi wanda ba za a iya kwatanta shi da galvanizing ba. Saboda haka, wannan hanyar plating ta dace musamman ga kowane nau'in acid mai ƙarfi, hazo na alkali da sauran yanayin lalata mai ƙarfi.

2. Ka'ida:

Hot tsoma zinc Layer yana samuwa a cikin matakai uku a ƙarƙashin ruwan zafi mai zafi:

1) Ƙarfe tushe surface an narkar da ta zinc bayani samar da wani tutiya-baƙin ƙarfe gami lokaci Layer;

2) Zinc ions a cikin alloy Layer sun kara yaduwa zuwa matrix don samar da nau'i mai banƙyama na zinc-iron;

3) Fuskar alloy Layer yana rufe murfin zinc.

3. Halayen ayyuka:

(1) Tare da kauri mai kauri mai tsantsa tsantsa Layer na tutiya wanda ke rufe saman karfen, zai iya guje wa matrix karfe da duk wani lamuni na lalata, kare matrix na karfe daga lalata. A cikin yanayi na gabaɗaya, saman tudun zinc yana samar da sirara mai ƙarfi da ɗigon zinc oxide Layer surface, yana da wahala a narke cikin ruwa, don haka yana taka rawar kariya akan matrix na ƙarfe. Idan zinc oxide da sauran abubuwan da ke cikin yanayi don samar da gishirin zinc wanda ba zai iya narkewa ba, kariya ta lalata ta fi dacewa.

(2) Akwai baƙin ƙarfe - zinc gami Layer, m, a cikin Marine gishiri fesa yanayi da masana'antu yanayi yi musamman lalata juriya;

(3) Saboda m hade, zinc-baƙin ƙarfe miscible, tare da karfi lalacewa juriya;

(4) Saboda zinc yana da kyau ductility, da gami Layer da karfe tushe da tabbaci a haɗe, don haka zafi plating sassa na iya zama sanyi stamping, mirgina, zane, lankwasawa da sauran siffofin ba tare da žata da shafi;

(5) Bayan zafi-tsoma galvanizing na karfe tsarin sassa, shi ne daidai da guda annealing magani, wanda zai iya yadda ya kamata inganta inji Properties na karfe matrix, kawar da danniya a lokacin forming da waldi na karfe sassa, kuma shi ne conducive zuwa juya. na karfe tsarin sassa.

(6) Fuskar kayan haɗi bayan zafi tsoma galvanizing yana da haske da kyau.

(7) Pure zinc Layer ne mafi filastik Layer na zafi tsoma galvanized Layer, da kaddarorin ne m kusa da tsarki tutiya, ductility, don haka shi ne m.

4. Iyakar aikace-aikace:

Aikace-aikacen galvanizing mai zafi yana faɗaɗa tare da haɓaka masana'antu da noma. Sabili da haka, samfuran da aka yi amfani da su a cikin masana'antu (kamar kayan aikin sinadarai, sarrafa man fetur, binciken ruwa, tsarin karfe, watsa wutar lantarki, ginin jirgi, da dai sauransu), aikin noma (kamar: ban ruwa, greenhouse), gine-gine (kamar: ruwa da kuma). iskar gas, jakar waya, ƙwanƙwasa, gidaje, gadoji, sufuri, da dai sauransu, an yi amfani da su sosai a cikin 'yan shekarun nan samfurori masu zafi masu zafi suna amfani da su sosai saboda kyawawan bayyanar su da kyau juriya lalata.
