Umehluko phakathi kwe-cold-dip galvanizing kanye ne-hot-dip galvanizing ekucutshungulweni kwamapayipi ensimbi

I-Hot Dip Vs I-Cold Dip Galvanizing

Ukugaya ngogesi okushisayo kanye nokugaya ngogesi okubandayo kokubili kuyizindlela zokumboza insimbi nge-zinc ukuvimbela ukugqwala, kodwa kuhluka kakhulu ngenqubo, ukuqina, kanye nezindleko. Ukugaya ngogesi okushisayo kuhilela ukucwilisa insimbi ebhavini elincibilikisiwe le-zinc, okudala ungqimba lwe-zinc oluqinile, oluhlanganisiwe ngamakhemikhali. Ukugaya ngogesi okubandayo, ngakolunye uhlangothi, kuyinqubo lapho kufakwa khona ukugqoka okucebile nge-zinc, ngokuvamile ngokufafaza noma ngokupenda.

Ekucutshungulweni kwamapayipi ensimbi, ukufaka i-galvanizing kuyinqubo ebalulekile yokuthuthukisa ukumelana nokugqwala, okuhlukaniswe kakhulu ngezindlela ezimbili: i-hot-dip galvanizing (HDG) kanye ne-cold galvanizing (Electro-Galvanizing, EG). Kunomehluko omkhulu phakathi kwalokhu okubili ngokwemigomo yokucubungula, izici zokumboza, kanye nezimo ezisebenzayo. Okulandelayo ukuhlaziywa okuningiliziwe okuvela kubukhulu bezindlela zokucubungula, izimiso, ukuqhathanisa ukusebenza, kanye nezinkambu zohlelo lokusebenza:

1. Ukuqhathaniswa kwezindlela zokucubungula kanye nezimiso

1. I-Hot-dip galvanizing (HDG)

Inqubo yokucubungula: Ipayipi lensimbi licwiliswa oketshezini lwezinc oluncibilikisiwe, bese i-zinc ne-iron zisabela ukuze zakhe ungqimba lwe-alloy.
Isimiso sokwakheka kwengubo:
Ukubopha kwensimbi: I-zinc encibilikisiwe isabela ne-matrix yepayipi lensimbi ukuze yakhe ungqimba lwe-Fe-Zn (isigaba se-Γ Fe₃Zn₁₀, isigaba se-δ FeZn₇, njll.), kanti ungqimba lwangaphandle luwungqimba lwe-zinc olumsulwa.
2. Ukuqinisa ngogesi (ukuqinisa ngogesi, i-EG)
Inqubo yokucubungula: Ipayipi lensimbi licwiliswa ku-electrolyte equkethe ama-ion e-zinc njenge-cathode, bese ungqimba lwe-zinc lufakwa yi-direct current.
Isimiso sokwakheka kwengubo:
Ukufakwa kwe-Electrochemical: Ama-ion e-zinc (Zn²⁺) ancishiswa abe ama-athomu e-zinc ngama-electron ebusweni be-cathode (ipayipi lensimbi) ukuze akhe uqweqwe olufanayo (ngaphandle kwengqimba ye-alloy).

2. Ukuhlaziywa Komehluko Wenqubo

1. Isakhiwo sokumboza

Ukushisa okushisayo:
Isakhiwo esinezingqimba: i-substrate → ungqimba lwe-alloy lwe-Fe-Zn → ungqimba lwe-zinc oluhlanzekile. Ungqimba lwe-alloy lunobulukhuni obuphezulu futhi lunikeza isivikelo esengeziwe.
Ukuqinisa okubandayo:
Isendlalelo esisodwa se-zinc, akukho ukuguquka kwe-alloy, kulula ukubangela ukugqwala ngenxa yomonakalo wemishini.
 
2. Ukuhlolwa kokunamathela
Ukushisa nge-galvanizing: Ngemva kokuhlolwa kokugoba noma ukuhlolwa kwesando, ukugqoka akulula ukukususa (ungqimba lwe-alloy luboshwe ngokuqinile ku-substrate).
Ukugaya okubandayo: Ukwemboza kungase kuwe ngenxa yamandla angaphandle (njengokukhuhla ngemuva kokuklwebha).
 
3. Indlela yokumelana nokugqwala
Ukushisa okushisayo:
Ukuvikelwa kwe-anode yomhlatshelo + isithiyo: Ungqimba lwezinc luyabola kuqala, bese ungqimba lwe-alloy lubambezela ukusabalala kokugqwala ku-substrate.
Ukuqinisa okubandayo:
Incike kakhulu ekuvikelweni kwezithiyo, futhi i-substrate ithambekele ekugqwaleni ngemva kokulimala kwesembozo.

3. Ukukhetha isimo sohlelo lokusebenza

3. Ukukhetha isimo sohlelo lokusebenza

Izimo ezisebenzayo zamapayipi ensimbi afakwe ngogesi ashisayo
Izindawo eziyingozi:izakhiwo zangaphandle (imibhoshongo yokudlulisa, amabhuloho), amapayipi angaphansi komhlaba, izikhungo zasolwandle.
Izidingo zokuqina okuphezulu:izisekelo zokwakha, izivikelo zomgwaqo omkhulu.
 
Izimo ezisebenzayo zamapayipi ensimbi agqunywe ngogesi abandayo
Indawo yokugqwala emnene:umsele kagesi wangaphakathi, uhlaka lwefenisha, izingxenye zezimoto.
Izidingo zokubukeka eziphezulu:indlu yemishini yasekhaya, amapayipi okuhlobisa (indawo ebushelelezi nombala ofanayo kuyadingeka).
Amaphrojekthi athinta izindleko:izikhungo zesikhashana, amaphrojekthi anesabelomali esiphansi.
