ASTM A179inotonhora inokweva isina musono kabhoni simbi pombiinonyanya kushandiswa muzvikamu zvakasiyana zvezvivakwa zvesimbi, kunyanya mushure mekuita ngura yezvidimbu zvesimbi zvakanyudzwa mu440 ~ 460.℃kunyunguduka zinc solution, kuitira kuti simbi yepamusoro yakanamatira kune zinc layer, iyo inotamba chinangwa chekuchengetedza.Iyi inzira inoshanda yesimbi corrosion, kushandiswa kweiyo huru maficha ndeaya anotevera:
(1) ASTM A179 inotonhora inodhonzwa isina musono vagadziri vepombi ine gobvu dense dense zinc layer yakavharwa neinotonhora inodhonzwa isina musono chubhu pamusoro, inogona kudzivirira inotonhora inodhonzwa isina musono chubhu matrix uye chero kusangana neyakaora mhinduro kuchengetedza simbi matrix kubva mukuora.Mumamiriro ekunze, pamusoro pe zinc layer kuti iite dhiri uye dense zinc oxide pamusoro, zvakaoma kunyungudika mumvura, saka simbi matrix inoita basa rekudzivirira.Kana zinc oxide uye zvimwe zvikamu zvemumhepo zvichigadzira insoluble zinc munyu, iyo anti-corrosion effect inonyanya kudiwa.
(2) Nesimbi - zinc alloy layer, yakasanganiswa nedense, uye ine yakasarudzika anti-corrosion mumhepo yegungwa uye mumhepo.
(3) ASTM A179 inotonhora inokweva isina musono pombi ine yakasimba kupfeka kuramba nekuda kwekubatanidzwa kweiyo yakasimba, zinc - iron miscible.
(4) Sezvo zinc ine yakanaka ductility, alloy layer yayo uye chigadziko chesimbi chakasungirirwa kune yakasimba, saka zvikamu zvinopisa-zvinoputika zvinogona kutonhora, kukunguruka, kudhirowa, kupeta uye kumwe kuumbwa pasina kukuvadzwa kwekuputira.
(5) Kupisa-dip galvanized structural simbi pombi, yakaenzana neanoremerwa kurapwa, inogona kunyatso kuvandudza ma mechanic zvimiro zvesimbi matrix kubvisa simbi inogadzira welding kushushikana, inoenderana nesimbi chimiro chekushandura.
(6) Pamusoro pepombi inotonhora yakadhonzwa isina musono mushure mekupisa kwemarata inopenya uye yakanaka.
(7) Yakachena zinc layer ndiyo yakanyanya kupisa galvanized layer yegalvanized layer, chimiro chayo chiri padyo ne pure zinc, ine ductility, saka izere nekuchinjika.
