Mapango emumigwagwa yezuva anofanira kunge achitonhorwa here kana kuti anopisa?

Mazuva ano, premium Q235 simbi coils ndiyo inonyanya kufarirwa zvinhumatanda ezuva. Nekuda kwekuti marambi ezuva remumugwagwa anopindwa nemhepo, zuva, uye mvura, kurarama kwawo kwenguva refu kunoenderana nekukwanisa kwawo kutsungirira ngura. Simbi yacho inowanzoitwa galvanized kuvandudza izvi.

Kune mhando mbiri dzezinc plating: inopisa-dip uye inotonhora-dip galvanizing. Nokutihot-dip galvanized steel matandavanonyanya kushingirira kune ngura, tinowanzo kuraira kuzvitenga. Ndeupi mutsauko pakati pehot-dip nechando-dip galvanizing, uye nei mapango anopisa-dip ane galvanized yemhando yepamusoro? Ngatitarisei naTianxiang, fekitori ine mukurumbira yekuChina yemumugwagwa.

1) Cold Galvanizing (Inonziwo electro-galvanizing): Mushure mekudzikisa uye kunhonga, simbi inoiswa mune zinc salt solution. Mhinduro yacho yakabatana neiyo negative electrode ye electrolysis midziyo, uye zinc plate inoiswa yakatarisana, yakabatana kune yakanaka electrode. Kana simba rakabatidzwa, sezvo ikozvino inofamba yakananga kubva kune yakanaka kuenda kune yakaipa electrode, yunifomu, dense, uye yakanyatso bonded zinc deposit layer mafomu pamusoro pepombi yesimbi.

2) Kupisa-dip galvanizing: Nzvimbo yesimbi yakanyungudutswa mu zinc yakanyungudutswa zvichitevera kuchenesa nekuita. Chidimbu chesimbi zingi chinokura pamusoro pesimbi semugumisiro wekuita kwe physicochemical pakati pesimbi ne zingi pa interface. Kana ichienzaniswa neinotonhora galvanizing, iyi nzira inoburitsa chisungo chakasimba pakati pekuputira uye substrate, inovandudza coating density, kusimba, kuchengetedza-isina kushanda, uye mutengo-kubudirira.

1) Maitiro ekugadzirisa: Mazita avo anoita kuti musiyano ujeke. Zinc inowanikwa pakamuri tembiricha inoshandiswa mumapombi esimbi anotonhora-dip, nepo zinc inowanikwa pa450°C kusvika 480°C inoshandiswa mukupisa-dip galvanizing.

2) Ukobvu hwekuputira: Kunyangwe kutonhora-kunyudza galvanizing kunowanzo kuburitsa ukobvu hwekuputira chete 3-5 μm, izvo zvinoita kuti kugadzirisa kuve nyore, haina kushomeka kwekuora. Kusiyana neizvi, kupisa-dip galvanizing kazhinji kunopa kukora kwe10μm kana kudarika, inova kakapetwa makumi akati wandei inoshingirira mukuora pane kutonhora-kunyudza mapango emagetsi emwenje.

3) Coating Structure: Iyo yekupfekedza uye substrate inopatsanurwa neyakafanana brittle compound layer mune inopisa-dip galvanizing. Zvisinei, nokuti kupfeka kwacho kunogadzirwa zvachose ne zinc, izvo zvinoita kuti yunifomu ifukidzwe ine pores shoma, ichiita kuti isanyanya kusvibiswa, izvi hazvina zvazvinoita pakudzivisa kwayo kuparara. Kusiyana neizvi, kutonhora-kunyura galvanizing kunoshandisa coating yakagadzirwa nemaatomu ezinc uye maitiro ekunamatira emuviri ane mapores akawanda, izvo zvinoita kuti iite zinyekenyeke kwezvakatipoteredza.

4) Mutengo Musiyano: Kugadzirwa kwekupisa-dip galvanizing kwakanyanya kuoma uye kwakaoma. Naizvozvo, makambani madiki ane michina yechikuru anowanzo shandisa inotonhora-dip galvanizing, zvichikonzera kuderera zvakanyanya. Zvikuru, zvakasimbiswa zvinopisa-dip galvanizing vagadziri vanowanzova nekutonga kwemhando kuri nani, zvichitungamira kumitengo yakakwira.

Vamwe vanhu vangati nyangwe vakaziva musiyano wechando-dip galvanizing uye hot-dip galvanizing, havasati vakwanisa kuziva mutsauko. Idzi inzira dzekugadzirisa dzisingaoneki nemaziso. Zvakadini kana mushambadzi asina kutendeseka akashandisa galvanizing inotonhora pane yekupisa-dip galvanizing? Chaizvoizvo, hapana chikonzero chekunetseka. Cold-dip galvanizing uyeinopisa-dip galvanizingzviri nyore kusiyanisa.

Nzvimbo dzakatonhora-dzinonyungudutswa dzakatsvedzerera, kunyanya dzakaita yero-girinhi, asi dzimwe dzinogona kunge dzakapenya, dzakatsvuka-chena, kana kuti chena dzine sheen yakasvibira. Vanogona kuita sevakasvibira kana kuti vane tsvina. Kupisa-dip galvanized nzvimbo, mukuenzanisa, dzakati ngwee, uye dzinogona kunge dzine zinc bloom, asi dzinotaridzika zvakanyanya kupenya uye dzinowanzoita chena-ruvara. Ngwarira kusiyana uku.
