Kupisa Dipped Galvanizing process inzira yekunamira pamusoro pesimbi nedariro rezinc kudzivirira ngura. Iyi nzira inonyanya kukodzera kune simbi uye simbi zvinhu, sezvo inobudirira kuwedzera hupenyu hwezvinhu uye inovandudza kusimba kwayo. Iyo general process yekupisa-dip galvanizing inosanganisira anotevera matanho:
1. Pre-atreatment: Chigadzirwa chesimbi chinotanga kuiswa pasi pepamusoro pekugadzirisa, iyo inowanzobatanidza kuchenesa, kusvibiswa, pickling uye kushandiswa kwemvura kuitira kuti simbi yesimbi yakachena uye isina tsvina.
2. Dip Plating: Simbi yakagadziriswa inonyudzwa mumushonga wezinc wakanyunguduka unopisa kusvika ku435-530 ° C. Simbi yacho inobva yanyikwa mubhavhu rezinc rakanyungudutswa. Pakupisa kwepamusoro, nzvimbo yesimbi inopindirana ne zinc kuti igadzire zinc-iron alloy layer, nzira iyo zinc inosanganiswa nepamusoro pesimbi kuti iite metallurgical bond.
3. Kutonhora: Mushure mokunge simbi yabviswa kubva kune zinc solution, inoda kunyoroveswa, iyo inogona kuwanikwa nekutonhora kwepanyama, kutonhora kwemvura kana kutonhora kwemhepo.
4. Mushure mekurapwa: Simbi yakatonhodzwa yakakwenenzverwa ingada kumwe kuongororwa uye kurapwa, sekubvisa zinc yakawandisa, passivation yekuvandudza kusaora kwemarara, uye kuzora mafuta kana kumwe kurapwa kwepamusoro kupa imwe dziviriro.
Zvimiro zvezvinopisa-dip galvanized zvigadzirwa zvinosanganisira yakanakisa corrosion resistance, yakanaka kushanda uye yekushongedza zvinhu. Kuvapo kwezinc layer inodzivirira simbi kubva mukuora kuburikidza nekuita kwechibairo anode, kunyangwe kana zinc layer yakuvadzwa. Pamusoro pezvo, maitiro ekupisa-dip galvanizing layer kugadzirwa kunosanganisira kuumbwa kwezinc-iron alloy phase layer nekunyunguduka kwesimbi base surface by zinc solution, kumwe kupararira kwezinc ions mune alloy layer mu substrate kuita zinc-iron intercalation layer, uye kuumbwa kweiyo yakachena zinc layer pane iyo zinc layer.
Kupisa-dip galvanizing inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira zvivakwa zvekuvaka, zvekufambisa, simbi uye migodhi, kurima, motokari, midziyo yemumba, makemikari emidziyo, petroleum processing, tsvakurudzo yegungwa, zvigadziro zvesimbi, kutumira simba, kuvaka ngarava uye mamwe minda. Madimikira akajairwa ezvigadzirwa zvinopisa-dip galvanized zvinosanganisira chiyero chepasi rose ISO 1461-2009 uye chiChinese chenyika chiyero GB/T 13912-2002, icho chinotsanangudza zvinodiwa pakukora kweiyo inopisa-dip galvanized layer, zviyero zveprofile uye nemhando yepamusoro.
