Menene bambanci tsakanin hot galvaninzed da sanyi galvanized?
Hot-tsoma galvanizing da sanyi galvanized bambanci:
1. Galvanizing, kuma aka sani da zafi tsoma galvanized, shi ne ingot narke a high yanayin zafi, da dama supplemental abu a wurin, sa'an nan tsoma galvanized karfe tsarin Ramin, da karfe bangaren a Layer na tutiya shafi . A abũbuwan amfãni daga zafi-tsoma galvanizing lalata da ikon, mannewa da taurin tutiya shafi ne mafi alhẽri.
"Cold plated" ko "plating", watau zinc gishiri bayani ta hanyar electrolysis, zuwa plating a kan shafi, kullum ba su da dumama, kananan adadin zinc, da rigar yanayi ne mai sauqi ka fadi a kashe.
2. Hot tsoma galvanized (galvanizing)
Hot-tsoma galvanizing wani sinadari magani, shi ne electrochemical dauki.
Cold galvanizing shine adireshin jiki, kawai goge saman saman tutiya, Layer na zinc yana da sauƙin faɗuwa. Gina a cikin amfani da zafi tsoma galvanizing.
Ci gaba da zafi tsoma galvanizing tsari: karfe → dumama → sanyaya ga zazzabi galvanized galvanized → sanyaya →
Cold galvanized zinc shine kawai 10-50g/m2, juriyarsa na lalata fiye da tsoma mai zafi galvanized mai yawa bambanci. Galvanized ta farashi mai rahusa.
Hot tsoma galvanized karfe jiki ne zafi tsoma galvanized surface a karkashin yanayin da mannewa da karfi, ba sauki fado kashe, ko da yake akwai zafi tsoma.galvanized bututuabin mamaki na lalata, amma a cikin dogon lokaci don saduwa da fasaha, bukatun kiwon lafiya.
3. Bambance-bambancen fasaha
Da farko, shi ne bambanci tsakanin tsari: zafi-tsoma galvanizing ne workpiece degreasing, pickling, dipping, bushewa ruwa nutsewa a cikin zurfafa tutiya wani lokaci, za a iya tashe.
Har ila yau aka sani da electro-galvanized sanyi galvanizing, shi ne don amfani da electrolysis na'urorin aiki yanki ta wurin ragewa, pickling sinadaran post a cikin tutiya gishiri bayani, da kuma haɗa da anode electrolysis kayan aiki; a wuri fadin sassa na tutiya farantin da aka haɗa zuwa electrolysis kayan aiki tabbatacce, iko a kan, amfani da halin yanzu daga cathode zuwa anode na directional motsi na workpiece za a ajiye a cikin wani Layer na zinc.
Tutiya gama da bambanci: babu sanyi galvanized zafi tsoma galvanizing m haske bayyanar, amma kauri na tutiya shafi na sanyi galvanizing al'amurran da zafi-tsoma galvanizing ne 'yan sau. Galvanized lalata juriya shima sau da yawa.
