Fa'idodi da rashin amfani na Trivalent Chromium Plating

Da farko, menene Trivalent?

Yana da akayan ado chrome plating, wanda zai iya samar da karce da juriya na lalata a cikin zaɓuɓɓukan launi daban-daban.Trivalent chromeana la'akari da madadin yanayin yanayi zuwa chromium hexavalent.

Na gaba, bari mu dubi wannan tsari da kyau don fahimtar fa'idarsa da illolinsa.

Amfani:

Amfanin datrivalent chromium tafiyar matakaiA kan tsarin chromium hexavalent yana da ƙarancin damuwa game da muhalli saboda ƙarancin guba na chromium trivalent, mafi girman yawan aiki, da ƙananan farashin aiki.

A cikin tsarin chromium trivalent, chromium hexavalent wani gurɓataccen wanka ne.Don haka, wanka ba ya ƙunshi kowane adadin chromium hexavalent da aka yarda da shi.Jimlar ma'auni na chromium na maganin trivalent chromium shine kusan kashi ɗaya cikin biyar na mafita na chromium hexavalent.

Sakamakon sinadarai na trivalent chromium electrolyte, misting baya faruwa a lokacin plating kamar yadda yake faruwa a lokacin plating chromium hexavalent.Amfani da trivalent chromium kuma yana rage matsalolin zubar da shara da tsadar kayayyaki.

Rashin hasara:

Rashin lahani na tsarin chromium trivalent shine cewa tsarin ya fi kulawa da gurɓatawa fiye da tsarin chromium hexavalent, kuma tsarin trivalent chromium ba zai iya yin cikakken kewayon kaurin farantin karfe wanda tsarin chromium hexavalent zai iya.Saboda yana da kula da gurɓatawa, tsarin trivalent chromium yana buƙatar ƙarin kurkura sosai da kulawar dakin gwaje-gwaje fiye da tsarin chromium hexavalent.Trivalent chromium baho na iya farantin kauri daga jeri zuwa 0.13 zuwa 25 µm.Ba za a iya amfani da shi don yawancin aikace-aikacen plating na chromium mai wuya ba.

An ƙera baho na chromium electroplating da farko don maye gurbin baho na chromium plating na ado.Samuwar wanka mai trivalent ya tabbatar yana da wahala saboda chromium trivalent yana narkewa a cikin ruwa don samar da hadaddun ions masu barga waɗanda ba sa sakin chromium da sauri.A halin yanzu, akwai nau'ikan hanyoyin chromium na trivalent guda biyu akan kasuwa: kwayar halitta daya da tantanin halitta biyu.Babban bambance-bambance a cikin matakai guda biyu shi ne cewa tsarin tsari na cell-biyu yana ƙunshe da ƙananan-zuwa-ba chlorides, yayin da tsarin tsari guda ɗaya ya ƙunshi babban taro na chlorides.

Bugu da ƙari, tsarin tantanin halitta biyu yana amfani da anodes na gubar da aka sanya a cikin akwatunan anode waɗanda ke dauke da maganin sulfuric acid mai narkewa kuma an yi su tare da membrane mai lalacewa, yayin da tsarin kwayar halitta guda ɗaya yana amfani da carbon ko graphite anodes wanda aka sanya a cikin hulɗar kai tsaye tare da su. da plating bayani.Ba a samun cikakkun bayanai kan waɗannan hanyoyin saboda baho na chromium na trivalent a halin yanzu a kasuwa na mallaka ne.

Anan ga manyan fa'idodin Trivalent chrome:

· Abokan muhali-ƙananan hayaki mai guba fiye da plating hexavalent

· Karancin sludge

· Rage farashin maganin ruwa

· Ƙananan ƙa'idodin gwaji da haɗin kai

Matsalolin sune kamar haka:

Ɗauki ɗan ƙaran tsada akan sinadarai & kiyayewa sabanin plating hexavalent.

· Wahala wajen zaɓin anode

· Complex bayani abun da ke ciki

· Wahalar shafi kauri karuwa
