Bambance-bambance a Galvanizing, Cadmium Plating, Chromium Plating, da Nickel Plating na Karfe Round Karfe

Mene ne bambance-bambance tsakanin tutiya plating, cadmium plating, chromium plating, da nickel plating na karfe bututu da kumairin bar?

1.Galvanizing

Halaye: Zinc yana da ɗan kwanciyar hankali a cikin busasshiyar iska kuma ba shi da sauƙin canza launi.A cikin ruwa da yanayi mai laushi, yana amsawa tare da oxygen ko carbon dioxide don samar da oxides ko alkaline zinc carbonate fina-finai, wanda zai iya hana zinc daga ci gaba da oxidize da kuma taka rawar kariya.Galvanized coatings gabaɗaya sha magani passivation.Bayan passivation a cikin chromic acid ko chromate bayani, kafaffen passivation fim din ba a sauƙi ya shafa ta iska mai laushi, yana haɓaka ikon hana lalatawa.Don sassan bazara, sassa na bakin ciki (kaurin bango <0.5m), da sassan ƙarfe waɗanda ke buƙatar ƙarfin injina, dole ne a aiwatar da cirewar hydrogen, yayin da sassan jan ƙarfe da jan ƙarfe na ƙarfe na iya buƙatar cire hydrogen.Zinc plating yana da ƙarancin farashi, aiki mai dacewa, da sakamako mai kyau.Matsakaicin yuwuwar tutiya yana da ƙarancin ƙarancin ƙarfi, don haka platin zinc shine rufin anodic akan ƙarfe da yawa.Aikace-aikace: Galvanizing ana amfani dashi sosai a cikin yanayin yanayi da sauran wurare masu kyau.Amma bai kamata a yi amfani da shi azaman ɓangaren juzu'i ba

2.Cadmium plating

Halaye: Ga sassan da ke da alaƙa da yanayin ruwa ko ruwan teku, kuma a cikin ruwan zafi sama da 70 ℃, plating cadmium yana da tsayin daka, yana da juriya mai ƙarfi, mai kyau, kuma yana narkewa a hankali a cikin dilute hydrochloric acid.Duk da haka, yana da narkewa sosai a cikin nitric acid, ba zai iya narkewa a cikin alkali, kuma oxides dinsa ba ya narkewa a cikin ruwa.Shafi Cadmium ya fi tutiya mai laushi, tare da ƙarancin ƙarancin hydrogen da mannewa mai ƙarfi.Bugu da ƙari, a ƙarƙashin wasu yanayi na electrolysis, murfin cadmium da aka samu ya fi kyau fiye da suturar zinc.Amma iskar da cadmium ke samarwa a lokacin narkewa yana da guba, kuma gishirin cadmium mai narkewa shima guba ne.A karkashin yanayi na gabaɗaya, cadmium shine rufin cathodic akan ƙarfe, kuma murfin anodic a cikin marine da yanayin zafi mai zafi.Aikace-aikace: Ana amfani da shi musamman don kare sassa daga lalatawar yanayi wanda ruwan teku ko makamancin maganin gishiri ke haifar da tururi mai cike da ruwan teku.Yawancin sassa a cikin masana'antun jirgin sama, kewayawa, da na'urorin lantarki, maɓuɓɓugan ruwa, da sassa masu zare ana lulluɓe da cadmium.Ana iya goge shi, phosphated, kuma a yi amfani da shi azaman kayan fenti, amma ba za a iya amfani da shi azaman kayan tebur ba.

3.Chrome plating

Halaye: Chromium yana da tsayin daka a cikin yanayi mai danshi, alkaline, nitric acid, sulfide, carbonate mafita, da kwayoyin acid, kuma yana da saukin narkewa a cikin hydrochloric acid da sulfuric acid mai zafi.A karkashin aikin kai tsaye, idan ana amfani da Layer na chromium azaman anode, yana da sauƙin narkewa a cikin maganin soda.Layer na chromium yana da mannewa mai ƙarfi, babban taurin, 800-1000V, juriya mai kyau, ƙarfin haske mai ƙarfi, da juriya mai zafi.Ba ya canza launi da ke ƙasa da 480 ℃, yana fara oxidize sama da 500 ℃, kuma yana rage girman taurin a 700 ℃.Rashin lahanta shi ne cewa chromium yana da wuya, gaggautsa, kuma mai saurin rabuwa, wanda ya fi bayyanawa lokacin da aka yi masa canjin tasiri.Kuma yana da porosity.Karfe chromium yana da sauƙin wucewa cikin iska don samar da fim ɗin wucewa, don haka canza yuwuwar chromium.Sabili da haka, chromium ya zama suturar cathodic akan ƙarfe.Aikace-aikace: Kai tsaye plating chromium a saman saman karfe sassa a matsayin anti-lalata Layer ba manufa, kuma shi ne kullum samu ta Multi-Layer electroplating (watau jan karfe plating → nickel → chromium) don cimma manufar tsatsa rigakafin da kuma ado.A halin yanzu, ana amfani da shi sosai don haɓaka juriya na ɓarna, gyare-gyaren girma, haske mai haske, da hasken ado na ado.

nickel plating

Halaye: Nickel yana da kwanciyar hankali mai kyau na sinadarai a cikin yanayi da kuma maganin alkaline, ba a saurin canza launi, kuma yana da oxidized a yanayin zafi sama da 600 ° C. Yana narkewa a hankali a cikin sulfuric acid da hydrochloric acid, amma yana da sauƙi a narkewa a cikin nitric acid.Yana da sauƙin wucewa a cikin nitric acid mai tattarawa don haka yana da kyakkyawan juriya na lalata.Launin nickel yana da babban taurin kuma yana da sauƙin amfani.

Sabon Gapower Metal Kamfanin ya ƙware a samar da chrome plated, galvanized, nickel plated bututun ƙarfe da zagaye karafa.Kamfanin yana da tarin tan 20000 na bututun ƙarfe zagaye.Za mu iya samar da daban-daban bayani dalla-dalla na karfe bututu, zagaye sanduna, goge karfe bututu, da goge shafts, ciki har da American, Jamus, Japan, da Turai matsayin.Barka da zuwa tambaya.
