Ukuhlonza i-electrogalvanized steel grating kanye ne-hot-dip galvanized steel grating

Esikhathini esedlule, umehluko phakathi kwe-electrogalvanized steel grating ne-hot-dip galvanized steel grating wawuncike kakhulu ekuhlolweni kwezinzwa zama-spangles ezinc. Ama-spangles e-zinc abhekisela ekubukekeni kwezinhlamvu ezibunjwe ngemva kokuba igridi yensimbi eshisayo ikhishwe ebhodweni elisha futhi ungqimba lwezinc luphole luqine. Ngakho-ke, ingaphezulu le-hot-dip galvanized steel grating ngokuvamile lilukhuni, linezipangle ezijwayelekile ze-zinc, kuyilapho ingaphezulu le-electrogalvanized steel grating libushelelezi. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe obusha, i-hot-dip galvanized steel grating ayisenazo izici ezijwayelekile zama-spangles ezinc ezivamile. Kwesinye isikhathi ingaphezulu le-hot-dip galvanized steel grating liyakhanya futhi likhanya kakhulu kunalelo le-electrogalvanized steel grating. Ngezinye izikhathi, lapho igriyitha yensimbi eshisayo ediphu kanye ne-electrogalvanized steel grating kubekwa ndawonye, ​​kuba nzima ukuhlukanisa ukuthi iyiphi igriyiti yensimbi ecwebileyo eyidiphu futhi iyini i-electrogalvanized steel grating. Ngakho-ke, lezi ezimbili azikwazi ukuhlukaniswa ngokubukeka njengamanje.

Ayikho indlela yokuhlonza yokuhlukanisa lezi zindlela ezimbili zokuvuza eShayina noma ngisho nakwamanye amazwe, ngakho-ke kuyadingeka ukufunda indlela yokuhlukanisa kokubili emsuka wetiyori. Thola umehluko phakathi kokubili kusukela isimiso galvanizing
, futhi uwahlukanise kusukela ekubeni khona noma ukungabikho kongqimba lwe-alloy ye-Zn-Fe empeleni. Uma sekuqinisekisiwe, kufanele kube neqiniso. Umgomo wokushibilika kwe-hot-dip galvanizing yemikhiqizo ye-steel grating ukucwilisa imikhiqizo yensimbi ngemva kokuhlanza nokwenza kusebenze oketshezini oluncibilikisiwe lwe-zinc, futhi ngokusabela nokusabalalisa phakathi kwensimbi ne-zinc, ingxube ye-zinc alloy ene-adhesion enhle ibekwa phezu kwemikhiqizo ye-steel grating. Inqubo yokwakheka kongqimba lwe-hot-dip galvanizing empeleni inqubo yokwenza ingxubevange ye-iron-zinc phakathi kwe-matrix yensimbi kanye nongqimba lwezinc oluhlanzekile olungaphandle kakhulu. Ukunamathela kwayo okuqinile nakho kunquma ukumelana kwayo nokugqwala okuhle kakhulu. Kusukela esakhiweni se-microscopic, ibhekwa njengesakhiwo esinezingqimba ezimbili.
Umgomo we-electrogalvanizing yemikhiqizo ye-steel grating ukusebenzisa i-electrolysis ukwakha ungqimba lwensimbi olulinganayo, oluminyene, oluboshwe kahle noma i-alloy phezu kwezingxenye ze-grating zensimbi, kanye nokwenza ukumboza phezu kwe-grating yensimbi, ukuze kuzuzwe inqubo yokuvikela i-grating yensimbi ekugqwaleni. Ngakho-ke, i-electro-galvanized coating iwuhlobo lwe-coating olusebenzisa ukunyakaza okuqondisayo kwamandla kagesi ukusuka ku-electrode enhle kuya ku-electrode engalungile. I-Zn2+ kuma-nucleates e-electrolyte, iyakhula futhi ibeke ku-grating substrate yensimbi ngaphansi kwesenzo samandla okwakha ungqimba olunothayela. Kule nqubo, ayikho inqubo yokusabalalisa phakathi kwe-zinc nensimbi. Ngokubuka kwe-microscopic, ungqimba oluhlanzekile lwezinc.
Empeleni, i-hot-dip galvanizing ine-iron-zinc alloy layer kanye ne-zinc ehlanzekile, kuyilapho i-electro-galvanizing ine-zinc ehlanzekile kuphela. Ukuba khona noma ukungabi khona kwe-iron-zinc alloy layer ekugqokeni kuyisisekelo esiyinhloko sokukhomba indlela yokugqoka. Indlela ye-Metallographic kanye nendlela ye-XRD isetshenziswa kakhulu ukuthola ukunamathela ukuze kuhlukanise i-electro-galvanizing kusukela ekushiseni kwediphu.
