Ipayipi elihlanganisiwe, eyaziwa nangokuthi ipayipi lensimbi eligoqiwe, ihlukaniswe ngezinhlobo ezimbili: i-hot-dip galvanizing kanye ne-electro-galvanizing. I-hot-dip galvanizing inesendlalelo se-zinc esijiyile futhi inezinzuzo zokumboza okufanayo, ukunamathela okuqinile, kanye nokuphila isikhathi eside kwenkonzo. Izindleko zamapayipi agoqiwe nge-electro ziphansi, ubuso abusheleli kakhulu, futhi ukumelana kwawo nokugqwala kubi kakhulu kunokwamapayipi agoqiwe nge-hot-dip. Ukuze kuthuthukiswe ukumelana nokugqwala kwamapayipi ensimbi, amapayipi ensimbi ajwayelekile agoqiwe. Amapayipi ensimbi agoqiwe ahlukaniswe ngezinhlobo ezimbili: i-hot-dip galvanizing kanye ne-electro-galvanizing. I-hot-dip galvanizing inesendlalelo se-zinc esijiyile. Ipayipi eligoqiwe eliqhutshwa umoya-mpilo: lisetshenziswa njengepayipi lokwenza insimbi eqhutshwa umoya-mpilo. Ngokuvamile, kusetshenziswa amapayipi ensimbi agoqiwe anobubanzi obuncane. Ukuze kuvinjelwe ukugqwala, amanye adinga ukugqwala ngempumelelo.
(1) Ukukhiqizwa okuhlanzekile okuyingqayizivele
Ipayipi elihlanganisiwe lisebenzisa inqubo ye-sulfate electroplating ye-zinc-iron alloy, okusho ukuthi kukhona ukubhoboka okuqondile phakathi kwemisele yokukhiqiza kanye nemisele ngaphandle kokukhishwa noma ukugcwala kwesisombululo. Inqubo ngayinye yenqubo yokukhiqiza yakhiwe uhlelo lokujikeleza kwegazi. Izixazululo ethangini ngalinye, okuyisisombululo se-asidi ne-alkali, isisombululo se-electroplating, ukukhishwa kokukhanya kanye nesixazululo se-passivation, njll., ziphinde zisetshenziswe futhi azivuzi noma zikhishwe ngaphandle kwesistimu. Imigqa yokukhiqiza inamathangi okuhlanza ama-5 kuphela, asebenzisa ukujikeleza kwegazi. Sebenzisa futhi ukhiphe amanzi njalo, ikakhulukazi ezinqubweni zokukhiqiza ezingakhiqizi amanzi angcolile ngaphandle kokuhlanza ngemva kokukhipha amanzi.
(2) Ukucaciswa kwemishini yokufaka i-electroplating
Ukufakwa kwamapayipi agqitshwe ngogesi kanye nokufakwa kwamapayipi ethusi ngogesi kufana nokufakwa kwamapayipi okuqhubekayo, kodwa imishini yokufakelwa ihlukile. Ithangi lokufakelwa laklanywa ngesimo somucu omncane wentambo yensimbi. Umzimba wethangi mude, ubanzi kodwa awujulile. Ngesikhathi sokufakwa kwamapayipi ngogesi, izintambo zensimbi zidlula emigodini bese zisakazeka ebusweni boketshezi ngomugqa oqondile, zigcina ibanga phakathi kwazo. Kodwa-ke, ipayipi eligqitshwe ngogesi lihlukile kuntambo yensimbi ngoba linezici zalo ezihlukile futhi imishini yethangi iyinkimbinkimbi kakhulu. Umzimba wethangi wakhiwe izingxenye eziphezulu nezingezansi. Ingxenye engenhla yithangi lokufakelwa kanti ingxenye engezansi yithangi lokugcina ukujikeleza kwesisombululo, okwenza umzimba wethangi ofana ne-trapezoid omfushane phezulu futhi obanzi phansi. Kukhona umzila wokusebenza kwe-electroplating yamapayipi agqitshwe ngogesi ethangini lokufakelwa. Kunezimbobo ezimbili ezidlula phansi kwethangi ezixhumana nethangi lokugcina elingezansi, futhi zakha uhlelo lokuphinda usebenzise isixazululo sokufakelwa ngomshini ongaphansi. Ngakho-ke, amapayipi agqitshwe ngogesi afana nokufakwa kwamapayipi ngogesi ngogesi, futhi izingxenye ezigqitshwe ngogesi ziyashintshashintsha. Nokho, ngokungafani ne-iron wire plating, isixazululo se-plating samapayipi e-galvanized naso siyashintshashintsha.
(3) Ukuthuthukisa i-sulfate galvanizing
Izinzuzo ze-sulfate galvanizing ukuthi ukusebenza kahle kwamanje kuphezulu ngamaphesenti ayi-100 futhi izinga lokufakwa liyashesha, okungenakuqhathaniswa nezinye izinqubo ze-galvanizing. Ngenxa yokuthi i-crystallization yengubo ayilungile ngokwanele, ikhono lokusabalala kanye nekhono lokufakwa ngokujulile alilungile, ngakho-ke lifanele kuphela amapayipi okufaka kanye nezintambo ezinezimo zejometri ezilula. Inqubo ye-sulfate electroplating zinc-iron alloy yenza ngcono inqubo yendabuko ye-sulfate galvanizing. Kugcinwa kuphela i-zinc sulfate eyinhloko kasawoti, bese izingxenye ezisele ziyalahlwa. Inani elifanele likasawoti wensimbi lifakwa kufomula entsha yenqubo ukuze kwakhiwe i-zinc-iron alloy coating kusukela ku-single metal coating yokuqala. Ukuhlelwa kabusha kwenqubo akugcini nje ngokuletha izinzuzo zokusebenza kahle kwamanje okuphezulu kanye nezinga lokufakwa okusheshayo kwenqubo yokuqala, kodwa futhi kuthuthukisa kakhulu ikhono lokufakwa kanye nekhono lokufakwa ngokujulile. Esikhathini esidlule, izingxenye eziyinkimbinkimbi bezingenakufakwa, kodwa manje zombili izingxenye ezilula neziyinkimbinkimbi zingafakwa, futhi ukusebenza kokuvikela nakho kuphakeme ngokuphindwe kathathu kuya kahlanu kunensimbi eyodwa. Umkhuba wokukhiqiza ufakazele ukuthi uma usetshenziselwa ukufakelwa izintambo namapayipi ngogesi okuqhubekayo, izinhlamvu zokumboza zincane futhi zikhanya kakhulu kunezokuqala, futhi izinga lokufakwa liyashesha. Ubukhulu bokumboza bufinyelela isidingo zingakapheli imizuzu emi-2 kuya kwemi-3.
(4) Ukuguqulwa kwe-sulfate zinc plating
Ukufakwa kwe-sulfate electroplating kwe-zinc-iron alloy kugcina kuphela i-zinc sulfate, usawoti oyinhloko we-sulfate zinc plating. Izingxenye ezisele ezifana ne-aluminium sulfate, i-alum (i-potassium aluminium sulfate), njll. zingafakwa ebhavini lokufaka i-plating ngesikhathi sokwelashwa ukuze kukhiqizwe imvula ye-hydroxide enganyibiliki. Susa; ukuze uthole izithasiselo eziphilayo, engeza i-powdered activated carbon ukuze uzisuse ngokuzixuba.
Ukuhlolwa okwenziwe abakhiqizi bamapayipi agqitshiwe kubonise ukuthi i-aluminium sulfate kanye ne-potassium aluminium sulfate kunzima ukuzisusa ngokuphelele ngesikhathi esisodwa futhi zinomthelela ekukhanyeni kwesembozo, kodwa akukubi kangako futhi kungasuswa ukuze kusetshenziswe. Ngalesi sikhathi, ukukhanya kwesembozo kungabuyiselwa ngokwelashwa ngesisombululo. Engeza okuqukethwe kwesithako okudingekayo ngokwenqubo entsha ukuze uqedele ukuguqulwa.
Uma ufuna ukwazi imininingwane eyengeziwe mayelana nepayipi lensimbi elenziwe nge-galvanized, sicela ukhululeke ukuxhumana nathi.
