Ipayipi lensimbi elicwebezelayo elishisayo: Ipayipi lensimbi elicwebezelayo elishisayo liyinsimbi yokuqala eyenziwe izingxenye ze-pickling, ukuze kukhishwe i-iron oxide ebusweni bezingxenye ezenziwe ngensimbi, ngemva kokukhetha, nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe. amathangi esisombululo esinamanzi okuhlanza, bese ethunyelwa ku-hot-dip Plating tank.
I-Cold galvanizing ibizwa nangokuthi i-electro-galvanizing: ukusetshenziswa kwemishini ye-electrolytic kuzoba ukufakwa ngemuva kokunciphisa, ukuqoqa ekubunjweni kukasawoti we-zinc esixazululweni, futhi kuxhunywe kumishini ye-electrolytic ye-electrode negative, ekufakweni okuphambene. uhlangothi lokubekwa kwepuleti le-zinc, elixhunywe kumshini we-electrolytic ku-electrode enhle exhunywe kugesi, ukusetshenziswa kwamandla kagesi ukusuka ku-electrode ephozithivu kuya ku-electrode eyinegethivu yendawo Ukunyakaza kokufakwa kuzofaka ungqimba lwe-zinc, ukufakwa okubandayo kokufakwa kuqala kucutshungulwe bese kufakwa i-zinc.
Umehluko omkhulu phakathi kwalokhu okubili umi kanje
1.Kunomehluko omkhulu endleleni yokusebenza
I-zinc esetshenziswa ekushiseni kwe-hot-dip galvanizing itholakala ekushiseni okungama-450 ℃ kuya ku-480 ℃; futhi kubandaipayipi lensimbiku-zinc, itholakala ekamelweni lokushisa ngenqubo ye-electroplating.
2.Kunomehluko omkhulu ekugqineni kongqimba lwamagalani
I-Hot-dip galvanized steel pipe zinc layer ngokwayo iwugqinsi, kukhona ukushuba okungaphezu kuka-10um, ungqimba olubandayo lwepayipi lensimbi enama-zinc lincane kakhulu, inqobo nje uma ubukhulu be-3-5um
3.Different surface smoothness
Cold galvanized steel pipe surface ayibushelelezi, kodwa uma kuqhathaniswa nobushelelezi obushelelezi be-hot-dip kungcono. I-Hot-dip galvanized nakuba ingaphezulu likhanya, kodwa limahhadlahhadla, kuzoba khona izimbali ze-zinc ezivelayo. Nakuba ubuso obubandayo obunama-galvanized bushelelezi, kodwa kuzoba grey, ukusebenza okunamabala, ukusebenza kahle kokucubungula, ukumelana nokugqwala akwanele.
4.Umehluko wamanani
Abakhiqizi ukuze kuqinisekiswe ikhwalithi, ipayipi lensimbi elishisayo elishisayo ngokuvamile ngeke lisebenzise i-electro-galvanized le ndlela yokufaka uthayela; kanye nalawo mabhizinisi amancane anezisetshenziswa eziphelelwe yisikhathi, iningi lawo lizosebenzisa i-electro-galvanized ngale ndlela, futhi ngaleyo ndlela intengo yamapayipi ensimbi abandayo abandayo iphansi kunepayipi lensimbi elidiphu elishisayo.
5.Indawo enama-galvanized ayifani
Ipayipi lensimbi elicwebezelayo elishisayo liyipayipi lensimbi eligcwele uthayela, kanti ipayipi lensimbi elibandayo likhandwe uhlangothi olulodwa lwepayipi lensimbi.
6.Umehluko omkhulu ekunamatheleni
Cold galvanized steel pipe adhesion than hot-dip galvanized steel pipe adhesion impofu, ngoba ipayipi lensimbi elibandayo lensimbi yepayipi matrix kanye nongqimba lwezinc luzimele komunye nomunye, ungqimba lwezinc luncane kakhulu, futhi lusanamathele nje phezulu. we-matrix yepayipi lensimbi, futhi kulula kakhulu ukuwa.
Umehluko wohlelo lokusebenza:
I-Hot-dipipayipi likathayelaisetshenziswa kabanzi ekwakhiweni, emishinini, ezimayini zamalahle, embonini yamakhemikhali, amandla kagesi, izimoto zikaloliwe, imboni yezimoto, umgwaqo omkhulu, ibhuloho, isitsha, izikhungo zemidlalo, imishini yezolimo, imishini kaphethiloli, imishini yokuhlola nezinye izimboni zokukhiqiza.
Ipayipi elibandayo lagalvanized esikhathini esidlule livame ukusetshenziswa, igesi kanye nesistimu yokuhlinzeka ngamanzi, kuyilapho kunezinye izici zokuthuthwa kwamanzi kanye nokuhlinzekwa kokushisa. Manje ipayipi lama-galvanized elibandayo selihoxisiwe ngokuyisisekelo emkhakheni wokuthuthwa kwamanzi, kodwa emanzini athile omlilo kanye nesakhiwo sefreyimu evamile sisazosebenzisa ipayipi elibandayo, ngoba ukusebenza kwe-welding yaleli payipi kusekuhle kakhulu.
Isikhathi sokuthumela: Jan-08-2024
