Hydrogen Peroxide hauv Deinking Ntawm Cov Ntawv Pov Tseg

Nyob rau hauv bleaching ntawm cov ntaub ntawv pov tseg, hydrogen peroxide yog pab tau rau tshem tawm cov number case. Thaum nws siv rau hauv cov tshuaj dawb ntawm cov khib nyiab pov tseg (OCC) pulp, cov khoom poob qis me me, thiab nws tuaj yeem txhim kho qhov ci ntawm OCC pulp thiab txhim kho cov xim ntawm cov tawv nqaij, uas yog qhov zoo rau kev tiv thaiv ib puag ncig thiab txo tus nqi ntawm kev kho dej khib nyiab. . Li Dong txoj kev tshawb fawb pom tias H-bleached 0CC pulp tuaj yeem txhim kho qhov ci ntawm cov tawv nqaij thaum txhim kho qee lub cev ntawm fiber ntau. Cov khoom ntawm lub cev ntawm cov bleached pulp, xws li lub nplhaib siab Performance index, kua muag Performance index, tawg index, yog zoo dua piv nrog OCC ntuj xim. Wang Huajie tau kawm txog hydrogen peroxide bleaching ntawm cov ntawv pov tseg deinked pulp tom qab lub sijhawm flotation, thiab tau txais cov txheej txheem thev naus laus zis zoo tshaj plaws rau H bleaching ntawm cov ntawv pov tseg deinked pulp. Chen Jia tau tham txog cov txiaj ntsig ntawm TAED activator ntawm hydrogen peroxide bleaching ntawm cov ntaub ntawv pov tseg. Cov txiaj ntsig tau pom tias TAED activator tuaj yeem txhim kho qhov ci ntsa iab thiab ruaj khov ntawm daim ntawv, thiab lub cev lub zog ntawm bleached pulp kuj tau txhim kho. Yang Li tau kawm txog cov txiaj ntsig ntawm ob lub enzymes lom, catalase thiab horseradish peroxidase, thiab peb qhov kev hloov pauv hlau ions, Cu2 ntxiv, Fe2 ntxiv thiab Mn2 ntxiv, ntawm cov dawb ntawm cov khib nyiab peroxide. Cov txiaj ntsig kev sim pom tau hais tias nrog kev nce ntxiv ntawm cov enzymes lom neeg ntxiv, qhov whiteness thiab residual hydrogen peroxide ntawm cov ntaub so ntswg poob qis, qhia tau hais tias tom qab ntxiv cov enzyme, qhov tsis zoo ntawm peroxide decomposition nce nyob rau hauv ib lub sijhawm. Los ntawm kev kawm kinetic ntawm hydrogen peroxide decomposition catalyzed los ntawm kev hloov hlau ions, nws pom tias qhov kub thiab txias plays lub luag haujlwm tseem ceeb hauv hydrogen peroxide decomposition. Zhang Shubin. tau kawm txog cov txiaj ntsig ntawm cov ntawv sau rau ntawm hydrogen peroxide bleaching ntawm cov ntaub ntawv pov tseg. Cov txiaj ntsig tau pom tias sib txawv fillers thiab lawv cov nyiaj hauv cov ntaub so ntswg muaj qhov sib txawv ntawm cov nyhuv bleaching ntawm peroxide ntawv.
