Oxalic acidyog cov organic acid nrog cov mis tshuaj ntawm H₂C₂O₄. Nws feem ntau yog siv rau hauv kev ntxuav, tshem tawm xeb, kev ua lag luam, kev tshuaj xyuas tshuaj lom neeg, kev tswj kev loj hlob ntawm cov nroj tsuag thiab lwm yam teb. Nws cov kua qaub muaj zog thiab cov khoom txo qis zoo ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau qhov xwm txheej. Ua tus neeg muag khoom oxalic acid, Aojin Chemical yuav qhia rau koj txog kev siv oxalic acid yog dab tsi?
Kev ntxuav thiab tshem tawm xeb
1. Tshem tawm cov hlau xeb thiab nplai
Oxalic acid tuaj yeem cuam tshuam nrog xeb (hlau oxide) los tsim cov tshuaj sib xyaw ua ke, uas feem ntau siv los ntxuav cov xeb ntawm qhov chaw ntawm pob zeb, vuas, thiab ntoo; nws kuj tseem tuaj yeem tshem tawm cov calcium scale hauv cov khoom siv hauv chav dej lossis boilers.
Kev ua kom dawb ntoo
Hauv kev ua cov khoom ntoo, oxalic acid tuaj yeem tshem tawm cov xim dub uas tshwm sim los ntawm cov hlau ion ua qias tuaj hauv ntoo thiab rov qab ua kom cov xim ntuj ntawm ntoo zoo li qub.
Kev siv rau kev lag luam thiab tshuaj lom neeg
1. Kev ua hlau
Oxalic acid yog siv rau anodizing ntawm txhuas los txhim kho qhov corrosion tsis kam; nws kuj tseem siv tau ua extractant rau cov hlau tsis tshua muaj.
2. Kev luam ntawv thiab zas xim rau ntaub
Ua ib qho mordant lossis bleaching aid, nws pab cov dyes lo rau cov fibers thiab txhim kho cov teebmeem dyeing.
Cov tshuaj lom neeg ua los ntawm cov khoom siv
Nws yog cov khoom siv raw rau kev npaj cov tshuaj xws li oxalates thiab oxalates, thiab siv dav hauv kev lag luam tshuaj, yas thiab lwm yam lag luam.
III. Kev tshawb fawb hauv chav kuaj thiab kev tshawb fawb
1. Kev tshuaj xyuas tshuaj lom neeg
Oxalic acid tuaj yeem siv los ua tus neeg sawv cev txo qis hauv kev sim titration
2 Kev npaj cov tshuaj buffer.
Sib xyaw nrog lwm cov kua qaub lossis ntsev, kho qhov pH ntawm lub kaw lus sim.
Cov kev ceev faj
1. Oxalic acidua rau khaus tawv nqaij thiab cov ntaub so ntswg. Hnav hnab looj tes thiab tsom iav thaum sib cuag
Cov xwm txheej khaws cia 3.
Nws yuav tsum tau kaw thiab khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog.
