Incazelo emfushane:

Ipayipi Lensimbi Elivunyiwe liyinsimbi evimbela ukugqwala eyenza isendlalelo se-zinc esivikelayo phezu kwepayipi lensimbi ye-carbon ngokusebenzisa i-hot-dip galvanizing (460°C uketshezi oluncibilikisiwe lwezinc) noma inqubo ye-electroplating. Inomshini wokunqanda ukugqwala okumbaxambili: ungqimba lwezinki luhlukanisa ngokomzimba ukuvikelwa kwe-anode okukhethekile okuphathelene ne-zinc (umonakalo usewubufakazi bokugqwala), okwandisa impilo yepayipi lensimbi endaweni eswakeme, ene-asidi ebuthakathaka kanye ne-alkali ibe iminyaka engu-20-30 (i-hot-dip galvanizing) noma iminyaka engu-5-10 (electrogalizing). Amandla ayo amapayipi ayisisekelo angaphezulu kuka-375MPa futhi asetshenziswa kakhulu ekwakheni izikafula, amapayipi amanzi omlilo, ukuchelela ngenkasa kwezolimo, izinsimbi zokugada zikamasipala namakhebula amakhebula. Inezinzuzo ezintathu ezibalulekile zokungakhathaleli, ukusebenza kwezindleko eziphakeme kanye nokufaka kalula. Isakhiwo sakudala/impahla yezokuthutha ezindaweni eziveziwe.

    Imininingwane Yomkhiqizo

    Inqubo yokukhiqiza yeamapayipi kathayela adiphu ashisayoiqala ngokulungiswa okuqinile kwendawo yepayipi yensimbi. Okokuqala, ukugcoba ngesisombululo se-alkaline kusetshenziswa ukususa amabala kawoyela, kulandele ukucosha ukususa ukugqwala nesikali phezulu, bese kugezwa futhi kucwiliswe ku-ejenti yokucwenga (imvamisa isixazululo se-zinc ammonium chloride) ukuvimbela ipayipi lensimbi ukuthi lingaphinde lifakwe oxidation ngaphambi kokucwiliswa oketshezini lwezinc futhi kuthuthukise ukumanzisa koketshezi oluyisisekelo sensimbi. Ipayipi lensimbi elakhiwe ngaphambili licwiliswa oketshezini lwezinki oluncibilikisiwe ezingeni lokushisa elifinyelela ku-460°C. Ipayipi lensimbi lihlala kulo isikhathi esanele ukuvumela insimbi ne-zinc ukuthi ibhekane nokusabela kwe-metallurgical, yakhe ungqimba oluqinile lwe-iron-zinc alloy ebusweni bepayipi lensimbi, futhi ungqimba lwe-zinc ehlanzekile lumbozwe ngaphandle kwe-alloy layer. Ngemva kokuba i-dip plating isiqediwe, ipayipi lensimbi liphakanyiswa kancane kancane liphume ebhodweni le-zinc, kuyilapho ukushuba kongqimba lwe-zinc kulawulwa ngokunembile ngommese womoya (ukugeleza komoya ngesivinini esikhulu) bese kukhishwa uketshezi oluningi lwe-zinc. Ngokulandelayo, ipayipi lensimbi lingena ethangini lamanzi okupholisa ukuze liphole ngokushesha futhi liphothulwe, futhi lingadluliswa ukuze liqhubeke lithuthukise ukumelana nokugqwala nokubukeka kwe-zinc enamathelayo. Ngemva kokudlula ukuhlolwa, iba yipayipi lensimbi elidiphu elishisayo elinokumelana nokugqwala okuhle kakhulu.

    Isicelo Esiyinhloko

    Izici

    1.Ukuvikela okukabili kongqimba lwezinc:
    Ungqimba oluminyene lwe-iron-zinc alloy (amandla okubopha aqinile) kanye nongqimba oluhlanzekile lwe-zinc kwakheka phezulu, luhlukanise umoya nomswakama, lubambezeleka kakhulu ukugqwala kwamapayipi ensimbi.

    2. Ukuvikelwa kwe-anode yomhlatshelo:
    Ngisho noma i-coating yonakaliswe kancane, i-zinc izogqwala kuqala (ukuvikelwa kwe-electrochemical), ivikela i-substrate yensimbi ekugugulekeni.

    3.Impilo ende:
    Endaweni evamile, impilo yesevisi ingafinyelela eminyakeni engu-20-30, okude kakhulu kunamapayipi ensimbi ajwayelekile (njengokuphila kwamapayipi apendiwe cishe iminyaka engu-3-5)

    Isicelo

    I-Hot-dipipayipi likathayelas zisetshenziswa kabanzi ekwakheni izakhiwo (ezifana trusses ifektri, isikafula), ubunjiniyela kamasipala (abaqaphi, izigxobo ukukhanya emgwaqweni, amapayipi amanzi), amandla namandla (imibhoshongo yokudlulisela, kubakaki photovoltaic), izikhungo zezolimo (amathambo abamba ukushisa, izinhlelo zokunisela), ukukhiqizwa kwezimboni (amashalofu, imigudu yokukhipha umoya) kanye neminye imikhakha emihle kakhulu yokumelana nokugqwala ngenxa yokuphila kwabo okude. Banikeza isivikelo esinganakekeli, esingabizi kakhulu futhi esithembekile endaweni yangaphandle, enomswakama noma eyonakalisayo enempilo yesevisi efinyelela eminyakeni engama-20-30. Ziyisisombululo esithandwayo sokulwa nokugqwala esikhundleni samapayipi ensimbi ajwayelekile.
