Hot dip galvanizing ea tšepe ea tšepe e boetse e bitsoa hot dip galvanizing.Li-ingots tsa zinc lia qhibiliha libakeng tsa tropike 'me lisebelisoa tse ling tse thusang li kenngoa ka har'a sekontiri se chesang.Joale likarolo tsa marang-rang tsa tšepe li kenngoa ka har'a tanka ea galvanizing 'me ho kenngoa lesela la galvanizing holim'a poleiti ea tšepe.Matla a chesang qoela galvanizing itšetlehile ka kutu ho hanyetsa ha eona, 'me ho khomarela le ho thatafala ha galvanized lakane ba molemo.Bongata ba poleiti ya galvanized steel after galvanizing.Kahoo sena ke palo e akaretsang ea zinki.
Sebopeho sa hot dip galvanizing layer e entsoe ka hot dip galvanizing layer, e entsoeng ka motsoako oa tšepe oa zinki pakeng tsa matrix a tšepe le lera le hloekileng la zinki.Sebopeho sa workpiece e thehoa ke tšepe zinki alloy lera e chesang, e le hore tšepe le hloekileng zinki lera ama e ikhethang.Ha tšepe ea tšepe e qoelisoa ka har'a tharollo ea zinki e qhibilihisitsoeng, zinki ea pele le tšepe ('mele) li thehoa sebopeho.Ena ke kristale e entsoeng ka liathomo tsa zinki ka har'a tšepe e tiileng ea tšepe.Ha liathomo tse peli tsa tšepe li kopantsoe hammoho, matla a khoheli a pakeng tsa liathomo a fokola haholo.
Kahoo, ha zinki e lekana ho qhibiliha ho tiileng, liathomo tse peli tsa zinki le tšepe lia qhalana.Liathomo tsa zinki tse ka har'a matrix ea tšepe li fetisetsoa ka har'a lesela la matrix, 'me likarolo tsa tšepe li thehoa butle-butle hore e be li-alloys.Motsoako oa zinki oa tšepe le motsoako oa intermetallic FeZn13 ka tharollo ea zinki e qhibilihisitsoeng le tlase ea lakane e chesang e ka sebelisoa e le slag ea zinki.Lera le hloekileng la zinki le entsoeng ka tharollo ea zinc leaching ke kristale ea hexagonal.
Ha mocheso o ntse o sebetsa ka mocheso o tšoanang 'me mocheso o tšoanang o bolokoa, palo ea tšepe e qhibilihisitsoeng ha e tšoane.Hoo e ka bang 500, tahlehelo ea tšepe e eketseha haholo ka ho eketsoa ha mocheso le ho kenya letsoho.E tlase kapa e phahame ho feta 480 ~ 510c, 'me tahlehelo ea epitaxial iron e lieha,' me ho thata ho fumana nako.Ka hona, motho e mong le e mong o tla bitsa 480 ~ 510c sebaka se kotsi se qhibilihang.
Sebakeng sena sa mocheso, tharollo ea zinki e senyeha haholo ho workpiece le pitsa ea zinki, 'me tšepe e lahleheloa ke likhato tse 560 tsa Celsius ho eketsa ka ho hlaka,' me zinki e tla ba karolo ea tšepe e ka holimo ho likhato tse 660 tsa Celsius, slag ea zinki e tla ekeletsoa. ka potlako, plating e ke ke ea sebelisoa.Ka hona, electroplating e etsoa ka mefuta e fapaneng ea likhato tse 430 ~ 450 tsa Celsius.
