Khoom siv:
Cov khoom no tuaj yeem tsim cov dej-soluble complexes nrog hlau ions xws li calcium, magnesium, hlau, txhuas, tooj liab, thiab manganese, tshwj xeeb tshaj yog nrog high-valent xim-forming hlau ions. Yog li ntawd, nws yog dav siv nyob rau hauv
① hydrogen peroxide bleaching synergist stabilizer ② dej softener ③ textile printing thiab dyeing kev lag luam auxiliaries
④ xim photosensitive cov ntaub ntawv ua cov tshuaj dawb⑤ analytical chemistry reference reagent
⑥ chelating titrant ⑦ kev lag luam tshuaj txhua hnub ⑧ kev lag luam tshuaj pleev ib ce
Ntawv: Feem ntau yog siv rau hauv pulp bleaching thiab decolorization. Feem ntau siv los ua bleaching stabilizer rau hydrogen peroxide, nws muaj kev sib koom ua ke thiab stabilizing cov teebmeem: Tsis tas li ntawd, cov khoom no kuj muaj zog complexing (chelating) nyhuv ntawm multivalent xim-forming hlau ions, tig cov xim-forming hlau ions rau hauv dej tsis muaj xim. -soluble complexes los txhim kho cov tawv nqaij ntawm cov tawv nqaij. Nws feem ntau yog siv rau hauv cov txheej txheem deinking khib nyiab. Nws tau ntxiv ua ke nrog tus neeg sawv cev deinking thaum lub sij hawm pulping. Tus nqi ib tuj ntawm cov ntawv pov tseg qhuav feem ntau yog 1-2 kg.
Textile printing thiab dyeing: Cov khoom no tshem tawm cov txiaj ntsig ntawm ntau cov ions ntawm cov xim dyes hauv lub cev los ntawm kev sib txawv (chelation) kom tsis txhob muaj xim sib txawv thiab xim ruaj khov, thiab ua tau raws li daim ntawv thov ntawm kev luam ntawv thiab dyeing. Nws yog feem ntau ntxiv thaum lub sij hawm kho dej kom complex cov hlau ions nyob rau hauv cov dej system kom tsis txhob muaj cov nyhuv ntawm hlau ions ntawm dyes. Tus nqi siv nyob ntawm seb hom thiab cov ntsiab lus ntawm cov hlau ions hauv lub cev, thiab cov nyiaj tshwj xeeb yuav tsum tau ua raws li kev sim ua.
