Ukukhishwa kwe-annealing okungaphandle komugqa kusho ukuthi ukufakwa kabusha kwensimbi okushisayo noma okubandayo kwepuleti lensimbi eligoqiwe kwenziwa ohlotsheni olungaphansi lwesithando somlilo noma isithando somlilo sohlobo lwekhava ngaphambi kokungena kulayini wezintambo ezicwebezelayo ezishisayo, ukuze kungabikho inqubo yokujula kuthayela. umugqa.Ipuleti lensimbi kufanele ligcine indawo ehlanzekile esebenzayo yensimbi emsulwa, engenawo ama-oxide nokunye ukungcola, ngaphambi kokwenza idiphu elishisayo libe galvanizing.Ngale ndlela, ishidi le-annealed surface oxide liqala lisuswe ngendlela yokukhetha, bese limbozwa ungqimba lwe-zinc chloride noma ingxube ye-ammonium chloride ne-zinc chloride solvent ukuze livikeleke, ukuze kuvinjwe ipuleti ukuthi liphinde lifakwe i-oxidized.
Le ndlela ngokuvamile iwukusetshenziswa kwepuleti elaminethiwe eligoqiwe njengezinto ezingavuthiwe, ipuleti lensimbi elifakwe emanzini lithunyelwa kuqala endaweni yokusebenzela yokucosha, nge-sulfuric acid noma i-hydrochloric acid ukuze kukhishwe ingaphezulu leshidi lensimbi elishisayo le-oksijini.Ngemva kokukhetha, ipuleti lensimbi lingena ngokushesha ethangini ukuze licwiliswe futhi lilinde ukufakwa kukathayela, okungavimbela ukukhishwa kabusha kwe-steel plate.Ngemuva kokukhetha, ukuhlanza amanzi, ukukhama, ukomisa, ebhodweni le-zinc, izinga lokushisa liye lagcinwa ku-445-465 ℃.
I-Hot dip galvanizing bese igcotshwa ngamafutha futhi ifakwe i-chrome.Izinga leshidi elinothayela oshisayo elikhiqizwe yile ndlela lithuthukiswa kakhulu uma liqhathaniswa nalelo ngendlela emanzi yokufaka uthayela.Ibalulekile kuphela ekukhiqizeni okuncane.Ulayini wokukhiqiza oqhubekayo wokugalela uthayela uhlanganisa uchungechunge lwezinqubo zokwelashwa ngaphambi kwesikhathi, njengokususwa kwe-alkali, ukucotshwa kwe-hydrochloric acid, ukugeza amanzi, ukumbozwa kwe-solvent, ukomiswa, njll., kanye nepuleti lokuqala lidinga ukuvalelwa esithandweni somlilo ngaphambi kokungena emugqeni wokwenza uthayela.
