Ipayipi eligayiwe, eyaziwa nangokuthi yipayipi lensimbi ye-Galvanized Steel, lihlukaniswe izinhlobo ezimbili: Hot-Clip Galvanizing and Electro-Galvanizing. I-hot-cpup galvaning ine-zinc ungqimba obukhulu futhi inezinzuzo zokuhlanganiswa okufanayo, ukunamathela okuqinile, kanye nempilo yenkonzo ende. Izindleko zamapayipi e-electro-galvanized ziphansi, ingaphezulu alibushelelezi kakhulu, futhi ukumelana kwalo kokugqwala kumbi kakhulu ukwedlula amapayipi acwebezelayo adonsa kanzima. Ukuze uthuthukise ukumelana nokugqwala kwamapayipi ensimbi, amapayipi ensimbi ajwayelekile angama-galvanied. Amapayipi ensimbi enziwe nge-Galvanized ahlukaniswe ngezinhlobo ezimbili: Hot-crup galvaning kanye ne-electro-galvanizing. I-tal-cpup galvaning ine-zinc ungqimba obukhulu. Ipayipi elishaywe le-oksijini elishayiwe: isetshenziswa njengepayipi lokushaya ngensimbi e-oksijini. Ngokuvamile, kusetshenziswa amapayipi ensimbi amancane we-weldeter. Ukuze uvikele ukugqwala, abanye badinga ukuguqulwa ngempumelelo.
(1) Ukukhiqizwa okuhlukile okuhlanzekile
Ipayipi eligayiwe lisebenzisa inqubo ye-sulfate electroplating ye-allwoy ye-zinc-iron, okusho ukuthi kukhona ama-percount aqondile phakathi kwemikhombe yomugqa wokukhiqiza kanye nemikhombe ngaphandle kwekhambi. Inqubo ngayinye yenqubo yokukhiqiza yakhiwa uhlelo lokujikeleza. Izixazululo ethangini ngalinye, okuyi-acid ne-alkali solution, ikhambi le-elekroplating, isixazululo sokukhanya kanye nesixazululo sokushisa, njll., Zivuselelwa kuphela noma zikhishwe ngaphandle kohlelo. Ulayini wokukhiqiza unamathangi angama-5 wokuhlanza, asebenzisa ukujikeleza kwegazi. Sebenzisa futhi njalo, ikakhulukazi ezinqubweni zokukhiqiza ezingakhiqizi amanzi angcolile ngaphandle kokuhlanza ngemuva kokuphambuka.
.
I-electroplating yamapayipi e-galvanized kanye ne-electroplating yezintambo zethusi ziyefana ne-electroplating eqhubekayo, kepha imishini yokufaka ama-plating ihlukile. Ithangi le-Plating yakhelwe ngesimo se-stender strip socingo sensimbi. Umzimba wethangi mude, ububanzi kodwa ujulile. Ngesikhathi se-electroplating, izintambo zensimbi zidlula ezimbobo bese zisakazeka endaweni enoketshezi emgqeni oqondile, zigcina ibanga phakathi kwazo. Kodwa-ke, ipayipi elihlanganisiwe lihlukile kulayini wensimbi ngoba linezici zalo ezihlukile nemishini yethangi iyinkimbinkimbi ngokwengeziwe. Umzimba wethangi wakhiwa ngezingxenye ezingenhla nezingaphansi. Ingxenye engenhla iyithangi lokuthwebula kanye nengxenye engezansi yithangi lokugcina izixazululo, lelona umzimba onjengethangi anjenge-trapezoid anciphise phezulu nangaphezulu. Kunesiteshi sokusebenza kwama-elecyliveling ye-galvanized electroning ethangini lokuthwebula. Kukhona ezimbili ngokusebenzisa izimbobo ezansi kwethangi elixhumana nethangi eliphansi lokugcina, futhi zakha uhlelo lokuvuselelwa kabusha kwe-plating ngephampu e-submable. Ngakho-ke, amapayipi ahlanganisiwe afana ne-Iron Wire Electroplating, kanti izingxenye ezinamanzi zinamandla. Kodwa-ke, ngokungafani ne-Iron Wire Plating, isixazululo se-platiating samapayipi e-galvanized nawo ashukumisayo.
(3) Ukusetshenziswa kwe-sulfate galvaning
Izinzuzo zeSulfate Galvanizing yizo ukuthi ukusebenza kahle kwamanje kuphakeme ngokuthi amazinga we-100% kanye ne-devitions desition kuyashesha, okungenakuqhathaniswa nezinye izinqubo ze-galvaning. Ngoba i-crystallization ye-coatiw ayilungile ngokwanele, amandla okuhambisa kanye nekhono elijulile lokusebenzisa amapayipi ampofu, ngakho-ke lilungele kuphela amapayipi nezintambo ezinamaphiko alula wejometri. Inqubo ye-vonfate electroplating zinc-iron alloy inqubo yenza inqubo yendabuko ye-sulfate galvanizing. Kugcinwe kuphela usawoti we-zinc sulfate kuphela, futhi izakhi ezisele ziyalahlwa. Inani elifanelekile likasawoti wensimbi lingezwa kwifomethi entsha yenqubo yokwenza i-Zinc-Iron Alloy Coating kusuka ku-coating eyodwa yensimbi eyodwa. Ukuhlelwa kabusha kwenqubo akugcini ngokuletha kuphela izinzuzo zokusebenza okuphezulu kwamanje kanye nezinga lokufaka ngokushesha lenqubo yoqobo, kepha futhi kuthuthukisa kakhulu amandla okuhambisa kanye nekhono elijulile lokuphamba. Esikhathini esedlule, izingxenye eziyinkimbinkimbi azikwazanga ukutholwa, kepha manje zombili izingxenye ezilula neziyinkimbinkimbi zingafakwa zifakwe, futhi ukusebenza okuvikelayo nakho kuphakama ama-3 kuye kwayisi-5 ukuphakama kwensimbi eyodwa. Ukusebenza Kwemikhiqizo Kufakazele ukuthi lapho kusetshenziselwa ukuqhubeka kwezintambo namapayipi, okusanhlamvu okunamafutha kulungile kunokwasekuqaleni, futhi isilinganiso sokubekwa sishesha. Ubukhulu be-coating bufinyelela kwisidingo kungakapheli imizuzu emi-2 kuya kwemi-3.
(4) Ukuguqulwa kwe-Sulfate Zinc Plating
I-Sulfate Electroplating ye-zinc-iron alloy kuphela igcina i-zinc sulfate, usawoti oyinhloko we-sulfate zinc twin. Izakhi ezisele ezifana ne-aluminium sulfate, i-alum (potassium aluminium sulfate), njll. Ingangezwa kubhavu lokuqopha ngesikhathi sokwelashwa ukukhiqiza i-infoluble hydroxide yezulu. Susa; Ngezengezo ze-organic, engeza ikhabhoni ecutshunguliwe ecushiwe ukuze uyisuse nge-adsorption.
Ukuhlolwa ngabakhiqizi bepayipi we-galvanized kukhombisile ukuthi i-aluminium sulfate kanye ne-potassium aluminium sulfate kunzima ukususa ngokuphelele ngasikhathi sinye futhi kube nomthelela ekukhanyiseni kokuhlanganiswa, kepha akukubi futhi kungakhishwa ukuze kusetshenziswe. Ngalesi sikhathi, ukugqama kwe-coating kungavuselelwa ngokwelashwa nekhambi. Faka okuqukethwe okudingekayo kwezithako ngokuya ngenqubo entsha ukuqedela ukuguqulwa.
Uma ufuna ukwazi imininingwane eminingi ngepayipi lensimbi ye-galvanized, sicela ukhululeke ukuxhumana nathi.
