Ishidi elinothayela lisho ipuleti lensimbi eliwugqinsi elinongqimba lwezinc olubekwe phezulu.I-hot-dip galvanizing iyindlela yokonga futhi enengqondo yokwelapha yokulwa nokugqwala evame ukukhethwa.Cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni isetshenziswa kule nqubo.
Ishidi elinothayela elokugwema ukugqwala ebusweni bepuleti lensimbi eliwugqinsi futhi likhulise impilo yalo yesevisi.Ingaphezulu lepuleti lensimbi eliwugqinsi limbozwe ungqimba lwezinki lwensimbi.Lolu hlobo lwepuleti yensimbi ewugqinsi ehlanganiswe ne-zinc lubizwa ngokuthi ishidi elinamandla.
Ngokwezindlela zokukhiqiza nezindlela zokucubungula, ingahlukaniswa ngezigaba ezilandelayo:
① Ipuleti lensimbi eliwugqinsi elidiphu elishisayo.Ishidi lensimbi elibandayo lifakwe emanzini okugeza e-zinc encibilikisiwe, ukuze ubuso beshidi lensimbi elibandayo lihlanganiswe nesendlalelo se-zinc.Kulesi sigaba, isihluthulelo siwukusebenzisa inqubo eqhubekayo yokufaka amadiphu ashisayo ekukhiqizeni, okungukuthi, ipuleti lensimbi eliwugqinsi epuletini licwiliswa ngokuqhubekayo ethangini lokucwenga elinezinki elincibilikisiwe ukwenza ishidi likathayela;
②Ishidi likathayela eliqiniswe okusanhlamvu.Lolu hlobo lwepuleti lensimbi eliwugqinsi nalo likhiqizwa ngendlela yokucwilisa okushisayo, kodwa ngokushesha ngemva kokuba seliphumile ethangini, liyashisisa libe cishe ku-500 ° C ukuze liliguqule libe ifilimu yepulasitiki eyingxube ye-aluminium ye-zinc nensimbi.Lolu hlobo lweshidi elinama-galvanized lunokunamathela okuhle kakhulu kwezingubo zezakhiwo kanye ne-welding kagesi;
③ Ishidi elifakwe ugesi.Ukukhiqizwa kwalolu hlobo lweshidi eliphekwe nge-electroplating kunomsebenzi omuhle kakhulu wenqubo.Kodwa-ke, ukugqoka kuncane, futhi ukumelana nokugqwala akukuhle njengalokho kweshidi elishisayo lokucwilisa;
④Ishidi elinothayela elinohlangothi olulodwa nezinhlangothi ezimbili.Ishidi elinothayela elinohlangothi olulodwa futhi elinamacala amabili, okungukuthi, izimpahla ezifakwe emanzini ashisayo ohlangothini olulodwa kuphela.Ngokuya nge-welding kagesi, ukufutha, ukwelashwa okulwa nokugqwala, ukukhiqizwa nokucubungula, njll., inokuguquguquka okunamandla kuneshidi elinamaceleni amabili.Ukuze kuqedwe isici se-zinc engagcotshiwe nhlangothi zombili, kunolunye uhlobo lweshidi likathayela elihlanganiswe ne-chromatographic zinc ngakolunye uhlangothi, okungukuthi, ishidi elinothayela elinomehluko nhlangothi zombili;
⑤ I-aluminium alloy, ishidi elihlanganisiwe eliyinhlanganisela.Yenziwe nge-zinc nezinye izinto zensimbi ezifana ne-aluminium, umthofu, i-zinc, njll. ukwenza ama-alloys e-aluminium noma ngisho namapuleti ensimbi ayinhlanganisela.Lolu hlobo lwepuleti lensimbi eliwugqinsi lunezici zokwelapha ezingavamile zokulwa nokugqwala kanye nezici ezinhle kakhulu zokufafaza;
Ngaphezu kwalokhu okuhlanu okungenhla, kukhona ishidi likathayela elimibalabala, ishidi elifuthwe ngengubo, ishidi likathayela eline-polyethylene elaminethiwe nokunye.Kodwa kulesi sigaba, okuvame kakhulu kuseyishidi elishisayo le-dip.
Ipuleti lensimbi engagqwali igama elijwayelekile lensimbi engagqwali emelana ne-asidi, imelana nezinto ezingagqwali ezibuthakathaka njengegesi, isitimu, amanzi, noma amamaki ensimbi anezakhiwo zensimbi engagqwali kubizwa nge-stainless steel plate;kuyilapho izinto ezimelana ne-solvent (i-asidi, i-alkali, usawoti kanye nokunye ukugqwala kwamakhemikhali ezinto eziphilayo) ) amamaki ensimbi amisiwe abizwa ngokuthi izinsimbi ezimelana ne-asidi.
Ngenxa yomehluko ekubunjweni kwazo zombili, ukumelana kwazo nokugqwala kuhlukile.Ngokuvamile, amapuleti ensimbi engagqwali ngokuvamile awamelani nokugqwala kwe-solvent, kuyilapho izinsimbi ezimelana ne-asidi ngokuvamile zinezakhiwo zensimbi engagqwali.Igama elithi “stainless steel plate” alibhekiseli nje kuphela ohlotsheni lwepuleti lensimbi engagqwali, kodwa futhi libonisa izinhlobo ezingaphezu kuka-100 zamapuleti ensimbi akhiqizwa ezimbonini.Ipuleti ngalinye lensimbi engenasici elithuthukisiwe futhi eliklanywe lizoba nezici ezinhle kakhulu ngenjongo yalo ekhethekile eyinhloko.Isihluthulelo sempumelelo ukuthola ukusetshenziswa okuyisisekelo kuqala, bese kuba yizinga lensimbi elifanele.Ngokuvamile kukhona amamaki ensimbi ayisithupha kuphela ahlobene nenjongo eyinhloko yesakhiwo sokwakha.Wonke ane-chromium engu-17-22%, futhi amamaki amahle ensimbi nawo ane-nickel.Ukwengeza i-molybdenum kuthuthukisa ukugqwala komoya futhi imelana kakhulu nomoya oqukethe i-fluoride.
Insimbi engagqwali isho insimbi ekwazi ukumelana nezinto ezibolayo ezibuthaka njengegesi, isitimu, namanzi, nezinto ezonakalisayo zamakhemikhali aphilayo njenge-asidi, i-alkali, nosawoti, okwaziwa nangokuthi insimbi engagqwali engamelana ne-asidi.Ezisetshenziswa ezithile, insimbi imelana nezinto ezibolayo ezibuthaka ngokuvamile ibizwa ngokuthi insimbi engagqwali, futhi insimbi imelana nokugqwala kwe-solvent ibizwa ngokuthi insimbi engamelana ne-asidi.Ngenxa yomehluko ekwakhiweni phakathi kwakho kokubili, eyokuqala ayimelani nokugqwala kwezincibilikayo, kuyilapho yakamuva ngokuvamile ayinabala.Ukumelana nokugqwala kwamapuleti ensimbi engagqwali kusezicini ze-aluminium alloy eziqukethwe kunsimbi.
