Ishidi elakhiwe ngamapulangwe libhekisela epuleti lensimbi elinongqimba lwezinc ebusweni balo. I-galvanization iyindlela eyongayo nephumelelayo yokuvimbela ukugqwala, engafinyelela imiphumela emihle yokuvimbela ukugqwala ngaphandle kokusebenzisa i-zinc eningi. Iningi le-zinc litholakala ngokusebenzisa
Izinga leshidi likathayela kufanele liqhathaniswe kusuka ezicini ezahlukahlukene njengokuzinza nokufana kokufaka uthayela, futhi yiziphi izinzuzo zeshidi likathayela?
1, Ukumelana nokugqwala okuqinile
Indlela yokwelapha ye-galvanizing ukufeza umphumela wokuvimbela ukugqwala. Ngakho-ke, ishidi lika-galvanized kufanele libe nokumelana okuhle nokugqwala. Ingaphezulu leshidi elinothayela lingamelana nokuguguleka kwemikhiqizo egqwalayo njenge-asidi ne-alkali, futhi ine
Izinga elithile lokumelana nomthelela livimbela ukulimala kwe-surface coating. Amashidi afakwe uthayela asetshenziswa ezintweni zikagesi zasendlini njengeziqandisi nemishini yokuwasha azosulwa izikhathi eziningi ukuze kugcinwe ukuhlanzeka, ngakho-ke kudingeka futhi abe nezinga elithile lokuvikela amanzi.
Ucansi lokuvikela izingozi zikagesi.
2. Izindlela zokwelashwa ezihlukene ezingaphezulu
Kunezindlela ezehlukene zokwelapha ezingaphezulu, ezingahlukaniswa cishe zibe yi-hot-dip galvanizing, i-alloying galvanizing, kanye ne-electrogalvanizing. I-hot dip galvanizing inqubo yokucwilisa ipuleti lensimbi elincanyana kubhavu we-zinc oncibilikisiwe, lapho ungqimba lwezinc lunamathela phezulu.
Futhi ukuze kuzuzwe umphumela wokuvimbela ukugqwala, le ndlela ingaqhuma ngokuqhubekayo ngakho-ke isetshenziselwa amapuleti ensimbi agingqelwe. Ubude bepuleti lensimbi eligoqiwe bude, futhi ukucwiliswa okuqhubekayo kwe-galvanizing kungafinyelela kokubili ukudaya nokwenza.
3. Ukucaciswa kwemikhiqizo ehlukahlukene
Ishidi elihle likathayela linezinhlobonhlobo zezinto kanye nosayizi bomkhiqizo. Ngokuvamile, imodeli yomkhiqizo iphrintiwe emaphaketheni noma phansi kwensimbi yomkhiqizo, okwenza uhleleke kakhulu futhi uthuthukise ukusebenza kahle kwezokuthutha ngesikhathi sokuhlukaniswa nokugcinwa. ukucwenga
Izinga lesayizi leshidi le-zinc livumela ukuchezuka, futhi uma ubukhulu beshidi likathayela bukhulu, likhulu iphutha elivumelekile. Kodwa-ke, ukukhiqizwa okujwayelekile kusetshenziselwa ukulawula ngokuqinile iphutha leshidi elinothayela.
Ishidi le-galvanized lidlula ubuchwepheshe obukhethekile bokucubungula, okwenza ukugqoka kuvikeleke ngokuphumelelayo insimbi, ukuvimbela ukugqwala, nokwandisa impilo yesevisi yensimbi. I-hot-dip galvanized coating ishubile futhi imelana kakhulu nokugqwala kunendlela ye-electroplating
Ukugqwala okunamandla. Okwezinto ezidinga ukuthintana njalo namanzi nezinto ezibolayo, kunconywa ukusebenzisa i-hot-dip galvanizing. Amashidi adumile angamathayili angalawula amaphutha okukhiqiza futhi enze amakhasimende akwazi ukuthenga imikhiqizo enosayizi ofanele.
