Titanium Gr7 Anode Phaj

Titanium Gr7 anode phaj hais txog ib hom anode ua los ntawm qib 7 titanium phaj, corrosion-resistant alloy uas muaj palladium. Cov phaj anode no feem ntau yog siv rau hauv electroplating thiab electrochemical txheej txheem uas yuav tsum tau muaj qib siab corrosion kuj thiab durability.

Hauv daim ntawv thov electroplating, lub phaj anode yog siv los ua qhov zoo electrode, qhov uas nws tso tawm ions rau hauv electrolyte los pab txhawb kev tso cov hlau ions mus rau saum npoo ntawm cov khoom raug plated. Hauv cov txheej txheem electrochemical, lub phaj anode yog siv los tsim ib qho tam sim no lossis tsim cov tshuaj tiv thaiv los ntawm kev tso cov hluav taws xob rau hauv electrolyte.

Nws yog siv rau steel sawb plating EGL / ETL thiab electro-galvanized phaj (EGL) nroj tsuag. Peb muaj cov neeg siv kawg hauv Brazil tau ntau xyoo. Nws yog tus yam ntxwv zoo corrosion kuj, processability, weldability thiab painting, mas siv nyob rau hauv steel phaj galvanizing industries. Electro-galvanizing cov khoom muaj xws li ob-sided, ib leeg-sab thiab sib txawv txheej nyob ntawm cov txheej txheem sib txawv; Qhov zoo yog tus yuam sij rau qhov zoo ntawm cov khoom siv electroplating;

Specification

Cov tshuaj tiv thaiv mechanism

Nws cov tshuaj tiv thaiv (ntawm anode nto): 2 H2O-4e →O2↑ + 4H+
Lub ntsiab cathodic cov tshuaj tiv thaiv (ntawm steel phaj nto): Zn2++ 2e → Zn / Sn2++ 2e → Sn
Cathode nto cov tshuaj tiv thaiv:: 2H2O + 2e → H2↑ + 2OH-

Qib 7 titanium kuj hu ua titanium-palladium alloy, yog corrosive heev nyob rau hauv ntau yam txo cov xov xwm. Titanium-palladium yog ib hom titanium alloy, muaj 0.1% ~ 0.25% ntawm palladium. Palladium ruaj khov nyob rau hauv huab cua thiab huab cua puag ncig ntawm chav tsev kub, thiab tiv taus hydrofluoric acid, Corrosion ntawm phosphoric acid, perchloric acid, hydrochloric acid thiab sulfuric acid vapor. Lub alloy muaj palladium ua titanium resistant rau localized corrosion nyob rau hauv high kub (saum lub boiling point) chloride. Tsis tas li ntawd, Pd yog ib qho qeeb eutectoid -stabilizing lub caij, nce nws cov ntsiab lus tuaj yeem txo qhov rhiab heev rau hydrogen embrittlement. Yog li ntawd, Gr7 titanium phaj yog tsis tshua muaj resistant rau crevice corrosion vim nws muaj zog corrosion kuj thiab hydrogen absorption peev.

Qhov zoo

Kev siv cov titanium anode daim hlau tuaj yeem muab ntau yam zoo, nrog rau kev ua haujlwm siab corrosion, zoo heev durability, thiab kev pab lub neej ntev.

Lawv siv cov Gr7 anode phaj uas tiv taus corrosion heev ua electroplating anode rau steel sawb plating EGL / ETL thiab electro-galvanized phaj (EGL) cov nroj tsuag. Gr7 titanium phaj muaj 0.15% Palladium (Pd) kom nws cov kev ua tau zoo corrosion, feem ntau nyob rau hauv kev txo qis. Nws yog ib qho tseem ceeb los muab tus cwj pwm corrosion ntawm titanium Gr 7 anode phaj hauv concentrated brines ntawm qhov kub siab tshaj 100 degree. Nws tau ua nyob rau hauv concentrated NaCl + KCl cov kev daws teeb meem uas muaj nitrates thiab fluorides. Cov txiaj ntsig tau pom tias titanium Gr7 anode phaj tau tiv taus qhov dav dav thiab hauv cheeb tsam corrosion. Qee cov qauv tau polarized rau qhov muaj peev xwm siab dua 4 volts. Tsis muaj ib qho ntawm cov kab nrib pleb nruj nreem raug kev txom nyem crevice corrosion. Lub xub ntiag ntawm fluoride txhawb kev txhim kho hauv cheeb tsam nyob ib puag ncig ntawm cov npoo ntawm qhov crevice qub.
