Hot-dip galvanized steel pipe: hot-dip galvanized simbi pombi ndiyo yekutanga simbi yakagadzirwa zvidimbu zve pickling, kuitira kubvisa iron oxide pamusoro pesimbi yakagadzirwa zvikamu, mushure mekunhonga, kuburikidza neammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride yakasanganiswa. aqueous solution matangi ekuchenesa, wozotumirwa kune inopisa-dip plating tank.
Cold galvanizing inonziwo electro-galvanizing: iko kushandiswa kwe electrolytic midziyo ichave fittings mushure mekudzikisira, pickling mukugadzirwa kwezinc salt mumhinduro, uye yakabatana ne electrolytic midziyo ye negative electrode, mune zvigadziriso zvakatarisana. divi rekuisa zinc plate, yakabatana neelectrolytic midziyo muelectrode yakanaka yakabatana nemagetsi, kushandiswa kwemagetsi ikozvino kubva kune yakanaka electrode kuenda kune negative electrode yegwaro rekufamba kwefittings kuchaisa layer. ye zinc, kutonhora kwezvipfeko kunotanga kugadziriswa uye ipapo zinc-plated.
Misiyano mikuru pakati pezviviri ndeiyi inotevera
1.Pane mutsauko mukuru munzira yekushanda
Iyo zinc inoshandiswa mukupisa-dip galvanizing inowanikwa pakupisa kwe450 ℃ kusvika 480 ℃; uye kutonhoragalvanized steel pipemu zinc, inowanikwa pakamuri tembiricha kuburikidza ne electroplating process.
2.Pane mutsauko mukuru mukukobvu kwechigadziko chegalvanized
Kupisa-dip galvanized simbi pombi zinc layer pachayo inenge yakakora, kune anopfuura 10um ukobvu, inotonhora yesimbi pombi zinc layer yakatetepa kwazvo, sekureba ukobvu hwe3-5um.
3.Different surface smoothness
Cold galvanized simbi pombi pamusoro haina kutsvedzerera, asi kana ichienzaniswa inopisa-dip galvanized smoothness iri nani. Kupisa-dip galvanized kunyangwe nzvimbo yacho ichipenya, asi yakakasharara, pachava nemaruva e zinc anoonekwa. Kunyangwe iyo pamusoro peinotonhora galvanized yakatsetseka, asi pachave ne grey, yakasvibiswa kuita, yakanaka kugadzirisa kuita, ngura kuramba haina kukwana.
4.Musiyano wemutengo
Vagadziri kuitira kuti vave nechokwadi chemhando, kupisa-kunyura kwakakurudzira simbi pombi kazhinji hazvizoshandisi electro-galvanized iyi nzira yekugadzira; uye makambani madiki-diki ane midziyo isingachashandi, mazhinji acho achashandisa electro-galvanized nenzira iyi, uye nekudaro mutengo wepombi inotonhora yesimbi yakaderera pane inopisa-dhipi yakabatiswa simbi pombi.
5.Galvanized surface haina kufanana
Hot-dip galvanized simbi pombi ndiyo pombi yesimbi yakavharidzirwa zvakazara, nepo pombi yesimbi inotonhora inobatidzwa divi rimwe chete repombi yesimbi.
6.Kusiyana kwakasiyana mukunamatira
Cold galvanized simbi pombi adhesion pane inopisa-dip galvanized simbi pombi adhesion haina kunaka, nekuti inotonhora galvanized simbi pombi simbi pombi matrix uye zinc layer yakazvimirira kubva kune imwe neimwe, iyo zinc layer yakatetepa kwazvo, uye ichiri kungobatanidzwa pamusoro. yesimbi pombi matrix, uye zviri nyore kwazvo kudonha.
Musiyano wekushandisa:
Hot-dipgalvanized pipeinoshandiswa zvakanyanya mukuvaka, michina, migodhi yemarasha, indasitiri yemakemikari, magetsi emagetsi, mota dzenjanji, indasitiri yemotokari, mugwagwa mukuru, bhiriji, mudziyo, zvivakwa zvemitambo, michina yekurima, michina yepetroleum, michina yekutsvaga uye mamwe maindasitiri ekugadzira.
Cold galvanized pombi munguva yakapfuura inowanzoshandiswa, gasi uye mvura yekupa system, nepo kune zvimwe zvinhu zvekufambisa kwemvura uye kupisa. Ikozvino pombi inotonhora yakabatiswa yabva kumunda wekufambisa kwemvura, asi mune imwe mvura yemoto uye yakajairwa furemu chimiro icharamba ichishandisa inotonhora galvanized pombi, nekuti kucheneswa kwepombi iyi kuchiri kwakanaka.
