Heino misiyano yatinopfupikisa pakati peTrivalent uye hexavalent chromes.
Musiyano Pakati PeTrivalent uye Hexavalent Chromium
Hexavalentchromium platingndiyo nzira yechinyakare yechromium plating (inonyanya kuzivikanwa se chrome plating) uye inogona kushandiswa pakushongedza uye inoshanda kupera.Hexavalent chromium plating inowanikwa nekunyudza substrates mubhavhu rechromium trioxide (CrO3) uye sulfuric acid (SO4).Iyi mhando yechromium plating inopa ngura uye kupfeka kuramba, pamwe nekunaka kukwezva.
Yemotokari inotungamira vhiri chikamu mune hexavalent chrome kupera
Hexavalent chromiumplatingine zvayakaipira, zvisinei.Iyi mhando yekuputira inoburitsa akati wandei maproducts ayo anonzi ane njodzi tsvina, anosanganisira lead chromates uye barium sulfate.Hexavalent chromium pachayo chinhu chine njodzi uye carcinogen uye inodzorwa zvakanyanya neEPA.Mumakore achangopfuura, mota dzeOEM dzakaita seChrysler dzakaedza kutsiva hexavalent chromium kupera nekuwedzera eco-hushamwari kupera.
Trivalent chromiumndiyo imwe nzira yekushongedza chrome plating, uye inoonekwa seyakanaka nharaunda kune hexavalent chromium, ine akawanda emhando dzakafanana;sezvakangoita hexavalent chrome kupera, trivalent chrome kupera kunopa kukwenya uye kusaita ngura uye inowanikwa mune dzakasiyana siyana sarudzo dzemavara.Trivalent chromium plating inoshandisa chromium sulfate kana chromium chloride sechinhu chayo chikuru, pane chromium trioxide;kuita trivalent chromium kushomeka kune hexavalent chromium.
Yakasanganiswa grill mune dema trivalent chrome pamusoro inopenya nickel
Nepo iyo trivalent chromium plating process yakanyanya kuoma kudzora, uye makemikari anodiwa anodhura kupfuura anoshandiswa kune hexavalent chromium, zvakanakira nzira iyi zvinoita kuti zviite kukwikwidza nedzimwe nzira dzekupedzisa.Iyo trivalent process inoda simba shoma pane iyo hexavalent process uye inogona kushingirira kuvhiringika kwazvino, zvichiita kuti ive yakasimba.Trivalent chromium's low toxicity inoreva kuti inodzorwa zvishoma, ichidzikisa tsvina ine ngozi uye mimwe mitengo yekuteerera.
Nemirau pamusoro pezvinhu zvine njodzi zviri kusimba muUS neEU, kudiwa kwekupedzisa zvine hushamwari kwezvakatipoteredza senge trivalent chrome kuri kuwedzera.
Hexavalent Chromium Plating Solution
Hard chromium plated deposits, ayo anowanzo kukora plating, anoshandiswa zvakanyanya mumigodhi nemaindasitiri endege uye kune hydraulics uye simbi yekugadzira michina.Izvo zvinoshandiswawo mukupedzisa kwezvokurapa uye zvekuvhiya michina.
Hexavalent chromium electrolytes inoda kunobva chromium ions uye imwe kana kupfuura zvinokonzeresa kuitira kuti ndiro.Kugadzirwa kwemaitiro echinyakare, kunonzi kugezwa kwakajairika, kune hexavalent chromium uye sulfate seyo chete inokonzeresa.
Proprietary additives iyo inogona kuwedzerwa kune yakajairwa hexavalent chromium plating yekugezesa yekugadzira nzira inonzi yakasanganiswa-catalyst mabhati sezvo izvo zvinowedzera zvine kamwechete kamwechete katuru kuwedzera kune sulfate.
Trivalent Chromium Plating Solution
Maelectrolyte e trivalent chromium plating solutions anosiyana muchemistry, asi ese ane tsime re trivalent chromium, iyo inowanzo wedzerwa se sulfate kana chloride munyu.Iwo zvakare ane solubilizing zvinhu zvinosanganiswa nechromium kuti zvibvumire kuti ipure muchishuwo chekuwedzera conductivity mumhinduro.
Wetting agents anoshandiswa kubatsira mukuita deposition uye kuderedza kushushikana kwepamusoro kwemhinduro.Iko kuderedzwa kwepasi tension kunobvisa kuumbwa kwemhute pane anode kana cathode.Iyo plating process inoshanda zvakanyanya seNickel yekugezesa chemistry pane yeHex chrome yekugezera.Iyo ine yakanyanya kutetepa maitiro hwindo pane hexavalent Chrome plating.Izvi zvinoreva kuti mazhinji emaitiro maparamita anofanirwa kudzorwa zvakanaka, uye zvakanyanya chaizvo.Kushanda kweTrivalent Chrome kwakakwira kupfuura iyo yeHex.Iyo dhipoziti yakanaka uye inogona kutaridzika chaizvo.
Hexavalent chromium plating ine zvayakaipira, zvisinei.Iyo inozivikanwa sevanhu carcinogen uye inogona kutungamirira kumatambudziko makuru ehutano.Rangarira chii chakaita Erin Brockovich zita remhuri?Rudzi urwu rwekuputira runoburitsa akati wandei maproducts anoonekwa seane njodzi.
Trivalent chromium platingine ushamwari hwezvakatipoteredza kupfuura hexavalent chromium;iyo electrodeposition process inowanzo gamuchirwa kuva inodarika ka500 ine muchetura pane hexavalent Chromium.Kubatsira kukuru kwematrivalent chromium maitiro ndeyekuti inochinja-chinja.Plating kugovera kwakawedzera yunifomu, barrel plating inogoneka kune trivalent chrome, izvo zvisingagoneke nehexavalent chrome.
