Ukuchongwa kwe-electrogalvanized steel grating kunye ne-hot-dip galvanized grating

Ngaphambili, ukwahlukana phakathi kwe-electrogalvanized steel grating kunye ne-hot-dip galvanized steel grating yayixhomekeke ekuhlolweni kweemvakalelo ze-zinc spangles. I-zinc spangles ibhekiselele kwinkangeleko yeenkozo ezenziwe emva kokuba i-hot-dip galvanized grating itsalwa ngaphandle kwembiza entsha kwaye umaleko we-zinc uyaphola kwaye uqina. Ngoko ke, umphezulu we-hot-dip galvanized grating udla ngokuba rhabaxa, kunye ne-zinc spangles eqhelekileyo, ngelixa umphezulu we-electrogalvanized steel grating ugudileyo. Nangona kunjalo, ngokuphuculwa kobuchwepheshe obutsha, i-hot-dip galvanized grating ayisekho iimpawu eziqhelekileyo ze-zinc spangles. Ngamanye amaxesha umphezulu we-hot-dip galvanized grating ikhanya ngakumbi kwaye ibonakalisa ngakumbi kune-electrogalvanized steel grating. Ngamanye amaxesha, xa i-hot-dip galvanized grating kunye ne-electrogalvanized steel grating ibekwe kunye, kunzima ukwahlula ukuba yeyiphi i-hot-dip galvanized grating kwaye yeyiphi i-electrogalvanized steel grating. Ke ngoko, ezi zimbini azinakwahlulwa ngokubonakala ngoku.

Akukho ndlela yokuchonga yokwahlula ezi ndlela zimbini ze-galvanizing e-China okanye nakwamanye amazwe, ngoko ke kuyimfuneko ukufunda indlela yokwahlula ezi zimbini kwingcambu yethiyori. Fumana umahluko phakathi kwezi zimbini ukusuka kumgaqo wokwenza igalvanizing
, kwaye bahlule kubukho okanye ukungabikho kwe-Zn-Fe i-alloy layer ngokubaluleka. Nje ukuba iqinisekisiwe, kufuneka ichaneke. Umgaqo-siseko wokutshisa i-galvanizing yeemveliso zensimbi kukuntywilisela iimveliso zentsimbi emva kokucoca kunye nokusebenza kwi-zinc liquide etyhidiweyo, kwaye ngokuphendula kunye nokusabalalisa phakathi kwentsimbi kunye ne-zinc, i-alloy ye-zinc i-alloy i-adhesion ifakwe kumphezulu weemveliso ze-steel grating. Inkqubo yokwenziwa kwe-hot-dip galvanizing layer yinkqubo yokwenza i-iron-zinc alloy phakathi kwe-matrix yentsimbi kunye ne-zinc ecocekileyo engaphandle. Ukunamathela kwayo okuqinileyo kukwamisela ukuxhathisa kwayo okugqwesileyo kokutya. Ukususela kwisakhiwo se-microscopic, sibonwa njengesakhiwo sesibini.
Umgaqo-siseko we-electrogalvanizing yeemveliso ze-steel grating kukusebenzisa i-electrolysis ukwenza iyunifomu, i-dense, kunye nentsimbi edibeneyo okanye i-alloy deposition layer phezu kwendawo yentsimbi yentsimbi, kunye nokwenza i-coating phezu kwe-grating yensimbi, ukuze kufezekiswe inkqubo yokukhusela i-steel grating kwi-corrosion. Ke ngoko, i-electro-galvanized coating luhlobo lokwaleka olusebenzisa intshukumo yalathiso yangoku yombane ukusuka kwi-electrode elungileyo ukuya kwi-electrode engalunganga. I-Zn2 + kwi-nucleates ye-electrolyte, ikhula kwaye ifake kwi-steel grating substrate phantsi kwesenzo sokukwazi ukwenza i-galvanized layer. Kule nkqubo, akukho nkqubo yokusabalalisa phakathi kwe-zinc kunye nentsimbi. Ukusuka kuqwalaselo lwe-microscopic, ngokuqinisekileyo ngumaleko ococekileyo we-zinc.
Ngokwenene, i-galvanizing ye-hot-dip ine-iron-zinc alloy layer kunye ne-zinc ecocekileyo, ngelixa i-electro-galvanizing ine-zinc ecocekileyo kuphela. Ubukho okanye ukungabikho kwe-iron-zinc alloy layer kwi-coating iyona siseko esisisiseko sokuchonga indlela yokugqoka. Indlela ye-Metallographic kunye nendlela ye-XRD isetyenziswa kakhulu ukukhangela i-coating ukwahlula i-electro-galvanizing ukusuka kwi-galvanizing eshushu-dip.
