Kupisa dip galvanizing, inozivikanwawo sekuti galvanizing, inzira yekunyudza zvinhu zvesimbi muzingi yakanyungudutswa kuti uwane simbi yakanyungudutswa.Electro galvanizing inowanzozivikanwa se "cold galvanizing" kana "water galvanizing";inoshandisa electrochemistry, uchishandisa zinc ingot seanode.Maatomu ezingi anorasa maerekitironi ova maion onyungudika mu electrolyte, ukuwo simbi ichiita seanode.Pacathode, maion zinc anogashira maerekitironi kubva musimbi uye anodzikiswa kuita zinc maatomu anoiswa pamusoro pesimbi kuti awane nzira yekunamira iyo inoumba yunifomu, dense, uye yakanyatso sunga simbi kana alloy deposition layer. Ichi chinyorwa chichakupa tsananguro yakadzama yekusiyana kwezviviri izvi.
1. Different coating thicknesses
Iyo inopisa dip galvanized coating kazhinji ine zinc layer yakakora, ingangoita 40 μm kana kupfuura, kana kunyange yakakwira se200 μm kana kupfuura.Iyo inopisa dip galvanized layer inowanzosvika ka10 kusvika ku20 iyo ye electroplated zinc layer.Iyo electroplated zinc coating yakanyanya kutetepa, inenge 3-15μm, uye uremu hwekuputira hunongova 10-50g/m2.
2. Yakasiyana galvanizing mari
Huwandu hwemakoiri esimbi anopisa akanyikwa haugone kuve hudiki.Kazhinji, zvishoma ndeye 50 ~ 60g / m2 kumativi ose uye iyo yakawanda ndeye 600g / m2.Iyo galvanized layer ye electro galvanized steel coils inogona kuve yakatetepa kwazvo, ine shoma ye15g/m2.Nekudaro, kana iyo yekupfekedza ichidikanwa kuve yakakora, iyo yekugadzira mutsara yekumhanyisa ichave inononoka, iyo isingakodzeri maitiro emaitiro emayuniti emazuva ano.Kazhinji, iyo yakawanda ndeye 100g/m2.Nekuda kweizvi, kugadzirwa kwe electro galvanized steel sheets kunorambidzwa zvakanyanya.
3. Chimiro chekuputira chakasiyana
Pane brittle compound layer pakati peyakachena zinc coating ye inopisa dip galvanized sheet uye simbi ndiro matrix.Kana iyo zinc yakachena yakavharwa inopenya, mazhinji emaruva ezinc anoumbwa, uye kupfeka kwakafanana uye hakuna pores.Maatomu ezinc ari muelectroplated zinc layer anongonaya pamusoro pesimbi ndiro, uye anonamirwa panyama nechepamusoro pesimbi.Kune akawanda pores, ayo anogona kukonzeresa gomba corrosion zviri nyore nekuda kwekuora media.Naizvozvo, kupisa dip marati ndiro mahwendefa anopokana kupfuura electro galvanized plates corrosion.
4. Maitiro akasiyana ekurapa kupisa
Mashizha esimbi anopisa akanyikwa anowanzo gadzirwa nemahwendefa akaomarara uye anogara achinyungudutswa uye anopisa anonyudzwa achiiswa galvanizing patambo yemagetsi.Mutsara wesimbi unopisa kwenguva pfupi uye wobva watonhodzwa, saka simba uye plastiki zvinokanganiswa kune imwe nhanho.Kuita kwayo kudhinda kuri nani pane Iyo imwe chete inotonhora yakaoma ndiro yakasiyana neinotonhora yakakungurutswa ndiro yesimbi mushure mekudzikisa uye kuvharika mumutsara wekugadzira wehunyanzvi.Mashizha esimbi anopisa akanyikwa ane mitengo yakaderera yekugadzira uye yakakura mashandisirwo emhando, uye ave iwo akasiyana siyana mumusika werata.Electro galvanized steel sheets anoshandisa simbi inotonhora yakakungurutswa semidziyo yakabikwa, iyo inovimbisa iyo yakafanana kugadzirisa kushanda kweanotonhora akakungurutswa mashiti, asi maitiro ayo akaomarara anowedzerawo mutengo wekugadzira.
5. Chitarisiko chakasiyana
Kumusoro kweiyo inopisa dip galvanized layer yakashata uye yakajeka, uye mumatambudziko akaoma pane zinc maruva;iyo electro galvanized layer yakatsetseka uye grey (yakasvibiswa).
6. Kusiyana kwekushandisa scopes uye maitiro
Kupisa-dip galvanizing kwakakodzera zvikamu zvakakura uye midziyo;hot-dip galvanizing ndiko kutora pombi yesimbi kutanga.Kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, inopfuudzwa neammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye chlorine.Zinc yakasanganiswa aqueous solution tangi yekuchenesa, yozotumirwa kune inopisa dip plating tank.
Inopisa yakanyudzwa galvanized simbi coil ine kuvharika kwakanaka, dense coating, uye isina tsvina inosanganisirwa.Iine zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.Kupisa-dip galvanizing kune kupikisa zviri nani pakuora kwemhepo kwesimbi yepasi pane electro-galvanizing.
Mashizha esimbi ane galvanized akagadzirwa neelectroplating ane mashandiro akanaka ekugadzirisa, asi kupfekedza kwacho kwakatetepa uye kushorwa kwecorrosion hakuna kunaka semapepa anopisa akanyikwa esimbi;huwandu hwezingi hwakanamirwa kune electro galvanized simbi coilis idiki kwazvo, uye chete yekunze pombi madziro anogezwa, nepo inopisa-dip galvanizing iri mukati nekunze.
