Tufafin Zinc

Zinc tsari ne na ƙarfe na ƙarfe.Daga ra'ayi na microscopic, aiwatar da zafi tsoma galvanizing shine ma'auni mai ƙarfi guda biyu, ma'auni mai zafi da ma'aunin musayar ƙarfe na zinc.Lokacin da aikin karfe ya nutse cikin kusan 450Ruwan tutiya narkakkar, ruwan zafin dakin daki ruwan tutiya zafi na aikin aikin, ya kai sama da 200, hulɗar zinc da baƙin ƙarfe ya zama bayyananne, zinc, baƙin ƙarfe ya shiga saman.Kamar yadda zafin jiki na workpiece sannu a hankali gabatowa da zafin jiki na zub da jini tutiya, workpiece surface kafa tare da daban-daban rabo na tutiya baƙin ƙarfe gami Layer, a matsayi tsarin tutiya shafi, tare da Extended lokaci, da girma daban-daban gami plating Layer gabatar daban-daban gudun rate.Daga wani macro hangen zaman gaba, yi na sama aiwatar workpiece immersed a cikin ruwa tutiya, tutiya ruwa tafasar faruwa a lokacin da tutiya, baƙin ƙarfe dauki hankali balance, tutiya surface hankali calmed.An yi aikin aikin;na zinc surface, da workpiece zafin jiki an saukar da hankali a kasa 200, da dauki da aka dakatar da tutiya, baƙin ƙarfe, zafi tsoma galvanized shafi yana da kauri ƙaddara.

A kauri daga cikin tutiya shafi manyan dalilai: wani tushe karfe bangaren, da surface roughness na karfe, da karfe na aiki abubuwa silicon da phosphorus abun ciki da kuma rarraba, ciki danniya na karfe, da workpiece lissafi, zafi tsoma galvanizing tsari. .A halin yanzu kasa da kasa da Sin matsayin suna zuwa kashi kashi bisa ga karfe kauri, kauri na tutiya shafi kauri da kuma zana gida ya kamata kai daidai kauri, domin sanin tutiya shafi anticorrosion yi.Daban-daban karfe kauri na workpiece, don cimma thermal ma'auni, da kuma zinc ion musayar ma'auni a lokuta daban-daban, sakamakon shafi kauri ne daban-daban.Matsakaicin kauri na ma'auni yana dogara ne akan tsarin ƙwarewar galvanizing a cikin samar da masana'antu, kauri na gida na kauri na tutiya ana la'akari da rarrabawar da ba ta dace ba na sutura da buƙatun kariyar lalata da ake buƙata.Saboda haka, ISO matsayin, ASTM matsayin, JIS matsayin da kasar Sin matsayin zinc shafi kauri bukata ne dan kadan daban-daban, da yawa iri daya.

A kauri daga cikin tutiya shafi ƙayyade aikin anticorrosion plating sassa.Don 3 mm da ke ƙasa da bakin karfe farantin karfe yana da santsi, yana da wuya a sami sutura mai kauri a cikin samar da masana'antu, ban da haka, bai dace da kauri na kauri na zinc plating na karfe ba kuma zai shafi ƙarfin mannewa na rufin da substrate da kuma shafi bayyanar ingancin.A lokacin farin ciki shafi zai haifar da shafi bayyanar m, sauki peeling, plating sassa ba zai iya jure karo a cikin aiwatar da handling da shigarwa.Idan akwai ƙarin karafa masu aiki na silicon da phosphorus, samar da masana'antu ya kasance mai matukar wahala mai laushi mai laushi, wanda shine abun da ke cikin siliki na ƙarfe a cikin tasiri tsakanin yanayin girma na zinc-iron gami Layer.
