Cov ntshiab hydrogen peroxide yog qhov ua kom rov tshwm sim thiab tsis ruaj khov, yooj yim decomposing rau hauv dej thiab oxygen. Cov xeeb ceem no tsis tsuas yog ua rau cov kev ploj ntawm nws cov khoom xyaw nquag tab sis kuj yuav muaj kev phom sij kev nyab xeeb hauv ib puag ncig. Los daws qhov kev sib tw no,Qhib AluminaUa lub luag haujlwm tseem ceeb ua "tus saib xyuas."
1. Lub Luag Haujlwm Tseem Ceeb: Stabilizer
Qhov Teeb Meem: Ntshiab Hydrogen Peroxide yog qhov tsis ruaj khov thiab nquag ua rau decomposition: 2h₂o₂ → 2h₂o + o₂↑
Qhov kev txiav txim siab decompose no tuaj yeem yog catalyzed los ntawm ntau yam, xws li cov cim hnyav hlau ions, lub teeb, kub, thiab alkaline ib puag ncig.
Kev txiav txim siab tsis tsuas yog txo cov kev lom zem ntawm hydrogen peroxide tab sis kuj ua rau muaj siab {{he oxygen nyob rau hauv ib lub taub ntim, posing qhov tawg kev pheej hmoo.
Yuav ua li cas ua kom Alumina ua haujlwm:
1. Impurity Adsorption: Ua kom Alumina yog ib qho ntxig, cov khoom siv tau tawg heev nrog thaj chaw loj thiab muaj peev xwm ua tiav. Nws ua zoo li hlau nplaum, nyiam tshaj tawm thiab txhav tas mus li ntawm cov tshuaj uas tuaj yeem ua rau cov kev txiav txim siab ntawm hydrogen peroxide.
2. CATALYST kev tshem tawm: los ntawm kev tshem tawm cov kev txiav txim siab catalysts, txoj kev txiav txim siab ntawm hydrogen polecules molecules yog qhov sib tw tsis zoo, yog li stabilizing kev daws teeb meem.
3. Kev Hloov Kho: Hydrogen Peroxide yog qhov ruaj khov nyob hauv cov acidic. Qhov saum npoo ntawm cov alumina ua kom zoo nkauj, uas tuaj yeem pab tswj cov acidic me ntsis ib puag ncig thiab txuas ntxiv inhibit decomposition.
2. Cov haujlwm theem nrab: Purification tus neeg sawv cev
Thaum lub caij hydrogen peroxide cov txheej txheem ntau lawm (tshwj xeeb tshaj yog cov txheej txheem ntawm cov txheej txheem), cov kab tawm ntawm cov organic impurities yuav muaj nyob hauv cov khoom.
Cov khoom tshaj tawm muaj zog ntawm cov neeg Alumina tsis muaj tsuas yog cov organic impurities thiab ua kom muaj qhov siab dua {0} {purity khoom.
3. Cov ntawv thov siv
Kev lag luam kev lag luam thiab chaw cia khoom: ua ntej hydrogen peroxide tawm lub Hoobkas, qee qhov kev ua kom muaj zog alumina (lossis lwm yam khoom siv Koj feem ntau pom txheej txheej dawb ntawm qhov ncauj dawb hauv qab ntawm cov lag luam muaj kev lag luam {}}- bilogen peroxide fwj. Qhov no yogQhib Alumina, uas txuas ntxiv ua haujlwm thaum lub sijhawm mus thiab khaws cia.
