Dab tsi yog txheej txheem ntawm MMO txheej?
Apr 27, 2025
MMO (sib xyaw hlau oxide) oxide) yog ib txheej txheem tshwj xeeb siv los siv cov txheej corrosion-tiv taus rau cov txheej txheem subttrates, feem ntau titanium lossis lwm yam hlau. Cov txheej txheej no tau siv dav hauv kev siv cov ntawv thov zoo li anodes rau Cathodic tiv thaiv, kev pab cuam hauv tshuab hluav taws xob, thiab lwm yam txheej txheem electrochemical. Cov txheej txheem dav dav ntawm MMO txheej yog raws li hauv qab no:
1. Substrate npaj
Xaiv cov khoom siv: lub substrate feem ntau yog titanium (qib 1 lossis 2).
Tu kom tu: lub substrate yog degreehed thiab etched (siv cov kua qaub acids zoo li oxalic lossis hydrochloric acid) kom tshem tawm cov oxide lossis cov paug thiab paug, kom ua kom zoo dua qub.
Roughening (xaiv tau): Qee cov txheej txheem muaj kev cuam tshuam sandblasting lossis tshuab puas tsuaj kom nce thaj tsam thaj tsam.
2. Txheej Ntawv Thov Txheej Txheem
Qhov txheej muaj cov hlau uas muaj nqi (piv txwv li, ruthenium, iRidium, Platinum) sib xyaw nrog hlau oxides (piv txwv li, titanium).
Qhov kev sib txuam thiab tuab ntawm cov txheej ncaj qha cuam tshuam rau kev ua haujlwm ntawm anode. Feem ntau siv txheej txheej txheej txheem suav nrog txhuam txhuam txhuam, cov txheej txau, thiab dip txheej. Txhuam txheej yog qhov haum rau anodes nrog thaj chaw me me lossis cov duab txaws, thaum cov txheej txau thiab siv cov txheej sib tsoo yog tsim nyog rau cov chaw loj lossis ntau lawm.
3. Kom Qhuav
Cov coated substrate yog qhuav ntawm kev kub ntxhov kom yaj cov kuab tshuaj.
4. Thermal decomposition
Cov txheej txheej qhuav yog raug rho tawm hauv lub cub tawg ntawm qhov kub (350-550 degree) hauv oxidizing cua.
5. Rov ua dua ntawm txheej & tua hluav taws
Ntau txheej (5-20 mus voj voog) tau thov kom ua tiav cov yam xav tau tuab (feem ntau 8-10 microns).
Txhua txheej yog qhuav thiab raug rho tawm haujlwm ua ntej tom ntej yog thov.
6. Tshaj Tawm - Kev Kho Mob
Sintering hardening yog cov txheej txheem ntawm tshav kub-kho cov coated titanium anode hauv ib puag ncig cua sov. Los ntawm kev kub siab-sintering, tshuaj lom neeg tshuaj lom neeg tshwm sim ntawm txheej txheej thiab cov titanium substrate, tsim cov txheej txheem sib raug zoo. Ib qho ntxiv, kev kho kub siab txhim kho cov ceev thiab tawv tawv ntawm txheej, yog li kev txhim kho lub anode corrosion tsis kam thiab tshuab zog.
