Polarization degree thiab qhib Circuit Court muaj peev xwm ntawm hluav taws xob cua sov raj electroplating
Hauv kev daws ntawm "4mol / LKOH ntxiv rau 2 feem pua PAA", qhov polarization degree ntawm txhuas nce nrog qhov nce ntawm PVA cov ntsiab lus hauv cov khoom ntxiv (saib daim duab 2a).
Tej zaum nws yuav yog macromolecular additives yuav ua rau nws nyuaj rau electromigration ntawm K ntxiv thiab OH -, tab sis tsawg dhau yuav cuam tshuam rau gelation. Qhov zoo tshaj plaws concentration ntawm PVA thaum "4mol / LKOH ntxiv rau 2 feem pua PAA" cov tshuaj ua ib tug colloid yog 2 feem pua; Nyob rau tib lub sijhawm, PVA ua rau muaj kev hloov pauv tsis zoo hauv qhov qhib lub peev xwm ntawm txhuas, thiab qhov qhib hluav taws xob muaj peev xwm ntawm txhuas hauv "4mol / LKOH ntxiv rau 2 feem pua PAA ntxiv rau 2 feem pua PVA" nthuav tawm qhov kev hloov pauv loj tshaj plaws (saib Table 1).
213 Kev coj ua thiab muaj peev xwm hloov pauv
Lub colloidal conductivity txo nrog qhov nce ntawm PVA cov ntsiab lus (saib Daim duab 1); Lub caij no, thaum nws tshwm sim los ua ib qho colloid ("4mol / LKOH ntxiv rau 2 feem pua PAA ntxiv rau 2 feem pua PVA"), cov conductivity yog siab dua li ntawm "4mol / LKOH ntxiv rau 25 feem pua PAA" colloid.
Thaum J=75mA/cm2, cov nyhuv ntawm PVA ntawm txhuas muaj peev xwm yog pom nyob rau hauv daim duab 3. PVA tuaj yeem txhim kho kev ua haujlwm ntawm colloidal electrolytes, thaum lub zog electrode ntawm txhuas yog qhov tsis zoo.
Cov nyhuv ntawm 22 Additive Na3PO4
221 Corrosion kev ua tau zoo
Cov nyhuv ntawm cov tshuaj ntxiv Na3PO4 ntawm qhov corrosion ntawm Al (hauv "4mol / LKOH ntxiv rau 2 feem pua PAA") yog qhia hauv Table 1.
Pom tseeb: ① Nrog rau qhov nce ntawm Na3PO4 cov ntsiab lus, corrosion tam sim no ntom ntawm txhuas txo; ② Thaum lub colloid tau tsim thawj zaug, tus nqi corrosion ntawm 8 feem pua Na3PO4 colloidal electrolyte ("4mol/LKOH ntxiv rau 2 feem pua PAA") (Jcor=512}mA/cm2) yuav luag sib npaug ntawm 25 feem pua APP colloidal electrolyte (4mol/LKOH) (Jcor{11}}mA/cm2).
222 Polarization degree thiab qhib Circuit Court muaj peev xwm
Raws li Na3PO4 cov ntsiab lus nce, qhov polarization degree ntawm txhuas nce (4mol / LKOH ntxiv rau 2 feem pua PAA) (saib daim duab 2b). Qhov no tej zaum yuav yog vim qhov nce hauv Na3PO4, uas txhim kho nws lub peev xwm adsorb K ntxiv thiab OH -, tab sis qhov ntau dhau yuav cuam tshuam rau gelation. Qhov zoo tshaj plaws concentration rau kev ua "4mol / LKOH ntxiv rau 2 feem pua PAA" cov tshuaj colloid yog 8 feem pua; Nyob rau tib lub sijhawm, Na3PO4 ua rau tsis zoo hloov pauv hauv Eocp ntawm txhuas, nrog qhov siab tshaj plaws ntawm Eocp tsis zoo hloov pauv tau pom hauv "4mol / LKOH ntxiv rau 2% PAA ntxiv rau 8 feem pua Na3PO4" (saib Table 1).
