Oxalic acidyog cov organic acid nrog cov tshuaj formula ntawm H₂C₂O₄. Nws yog tsuas yog siv nyob rau hauv tu, xeb tshem tawm, industrial ua, tshuaj ntsuam xyuas, cog kev loj hlob txoj cai thiab lwm yam teb. Nws muaj zog acidity thiab zoo txo cov khoom ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau qhov xwm txheej. Raws li tus neeg muag khoom oxalic acid, Aojin Chemical yuav qhia rau koj tias kev siv oxalic acid yog dab tsi?
Ntxuav thiab tshem tawm xeb
1. Tshem tawm cov hlau xeb thiab nplai
Oxalic acid tuaj yeem hnov mob nrog xeb (hlau oxide) los tsim cov khoom sib xyaw ua ke, uas feem ntau siv los ntxuav cov xeb ntawm cov pob zeb, vuas, thiab ntoo; nws tseem tuaj yeem tshem cov calcium scale hauv cov khoom siv hauv chav dej lossis boilers.
Ntoo bleaching
Hauv kev ua cov khoom siv ntoo, oxalic acid tuaj yeem ua rau cov tawv nqaij dub tshwm sim los ntawm cov hlau ion muaj kuab paug hauv cov ntoo thiab kho cov xim ntawm cov ntoo.
Kev lag luam thiab tshuaj siv tshuaj
1. Hlau ua
Oxalic acid yog siv rau anodizing ntawm txhuas los txhim kho qhov corrosion kuj; nws tseem tuaj yeem siv los ua cov extractant rau cov hlau tsis tshua muaj hauv ntiaj teb.
2. Textile printing thiab dyeing
Raws li mordant lossis bleaching pab, nws pab dyes adhere tusyees rau fibers thiab txhim kho cov teebmeem dyeing.
Synthetic tshuaj
Nws yog cov khoom siv raw rau kev npaj cov tebchaw xws li oxalates thiab oxalates, thiab yog siv dav hauv kev siv tshuaj, yas thiab lwm yam lag luam.
III. Laboratory thiab scientific kev tshawb fawb
1. Kev tshuaj ntsuam chemistry
Oxalic acid tuaj yeem siv los ua tus neeg sawv cev txo qis hauv kev sim titration
2 Kev npaj cov kev daws teeb meem tsis zoo.
Sib tov nrog lwm cov kua qaub los yog ntsev, kho cov pH ntawm qhov kev sim.
Cov kev ceev faj
1. Oxalic acidyog irritating rau ntawm daim tawv nqaij thiab mucous daim nyias nyias. Hnav hnab looj tes thiab tsom iav thaum sib cuag
Cia tej yam kev mob 3.
Nws yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob muaj oxidants muaj zog.
