Oxalic acid hmoov tsum Aojin Chemical muaj qib kev lag luam 99.6%oxalic acid ntawm Hoobkas nqi. Tsis ntev los no, ntau tus neeg muas zaub tau nug txog kev siv oxalic acid hmoov. Niaj hnub no, Aojin Chemical, tus neeg muag khoom oxalic acid, yuav qhia rau koj txog kev siv oxalic acid. Oxalic acid, feem ntau yog tsim los ntawm oxalic acid nrog cov tshuaj formula C₂H₂O₄, feem ntau yog siv hauv kev lag luam, tu txhua hnub, kev tshawb fawb tshawb fawb, thiab lwm yam. Cov ntsiab lus yog raws li nram no:
1. Muaj: Cov ntawv thov tseem ceeb raws li cov khoom siv tshuaj
Oxalic acid muaj zog acidity thiab muaj peev xwm tsim cov soluble complexes los yog precipitates nrog hlau ions ua rau nws nrhiav tau tom qab hauv kev lag luam. Cov ntawv thov uas muaj xws li:
2. Kev kho hlau
Kev tshem tawm xeb thiab ntxuav: Oxalic acid dissolves oxides ntawm cov hlau nto (xws li hlau xeb Fe₂O₃ thiab tooj liab xeb CuO), tsim cov oxalates soluble. Nws yog feem ntau siv rau hauv pretreatment ntawm steel thiab hlau qhov chaw (xws li xeb tshem tawm ua ntej electroplating) thiab nyob rau hauv lub refurbishment thiab tu ntawm hlau. 2. Boiler / Yeeb Nkab Descaling: Oxalic acid reacts nrog scale Cheebtsam xws li calcium carbonate (CaCO₃) thiab magnesium sulfate (MgSO₄) tsim dej-soluble calcium oxalate (ceeb toom: calcium oxalate tsis tshua muaj solubility, yog li cov concentration yuav tsum tau tswj kom tsis txhob muaj nag lossis daus). Nws yog siv rau descaling industrial boilers thiab kav dej.
3. Textile thiab Printing thiab Dyeing Kev Lag Luam
Bleaching Agent: Oxalic acid tau txo cov khoom, rhuav tshem cov pigments ntawm textiles (xws li ntuj pigments los yog dye residues nyob rau hauv paj rwb thiab linen fibers). Nws yog siv los ua tus neeg sawv cev pabcuam tshuaj dawb (feem ntau ua ke nrog hydrogen peroxide txhawm rau txhim kho kev ua kom zoo dua qub).
4. Dyeing Auxiliary: Nws khi rau cov hlau ions (xws li hlau thiab tooj liab ions) hauv cov ntaub, tiv thaiv lawv los ntawm kev cuam tshuam cov xim dyeing thiab txhim kho dyeing uniformity thiab vividness.
Lwm Cov Kev Siv Hluav Taws Xob: Raws li cov khoom siv raw rau cov organic synthesis, nws yog siv los tsim cov khoom siv tshuaj xws li oxalate esters thiab oxalamides (piv txwv li, dimethyl oxalate tuaj yeem siv rau hauv kev sib txuas ntawm cov tshuaj intermediates).
5. Hauv kev lag luam tawv, nws yog siv rau de-ashing thiab neutralization thaum lub sij hawm tanning txheej txheem, thiab kho pH nqi ntawm tawv. Hauv cov ntsiab lus, oxalic acid hmoov yog cov tshuaj ua haujlwm tau zoo, nrog rau nws cov ntawv thov tseem ceeb tsom rau kev ua lag luam thiab kev tu tshwj xeeb.
Peb zoo siab tos txais cov neeg siv khoom nrhiav oxalic acid tiv tauj peb ntawm Aojin Chemical, qhov twg peb tuaj yeem muab cov khoom zoo, zoo rau koj.oxalic acidcov khoom.
