Oxalic acidndi organic acid yokhala ndi mankhwala a H₂C₂O₄. Amagwiritsidwa ntchito makamaka poyeretsa, kuchotsa dzimbiri, kukonza mafakitale, kusanthula mankhwala, malamulo akukula kwa zomera ndi zina. Kuchuluka kwake kwa acidity komanso kuchepetsa kwabwino kumapangitsa kuti izikhala ndi gawo lofunikira pazochitika zingapo. Monga othandizira oxalic acid, Aojin Chemical akugawana nanu ntchito za oxalic acid?
Kuyeretsa ndi kuchotsa dzimbiri
1. Kuchotsa dzimbiri lachitsulo ndi sikelo
Oxalic acid amatha kuchita ndi dzimbiri (iron oxide) kupanga zinthu zosungunuka, zomwe nthawi zambiri zimagwiritsidwa ntchito kuyeretsa madontho a dzimbiri pamwamba pa miyala, matailosi, ndi matabwa; imathanso kuchotsa sikelo ya calcium mu zida za bafa kapena ma boilers.
Wood bleaching
Pokonza zinthu zamatabwa, oxalic acid amatha kusokoneza mawanga akuda omwe amayamba chifukwa cha kuipitsidwa kwa ayoni mumitengo ndikubwezeretsanso mtundu wachilengedwe wa nkhuni.
Kugwiritsa ntchito mafakitale ndi mankhwala
1. Kukonza zitsulo
Oxalic asidi ntchito anodizing zotayidwa kumapangitsanso kukana dzimbiri pamwamba; itha kugwiritsidwanso ntchito ngati chochotsera zitsulo zosowa zapadziko lapansi.
2. Kusindikiza nsalu ndi kudaya
Monga chithandizo cha mordant kapena bleaching, imathandizira utoto kumamatira mofanana ndi ulusi komanso kumapangitsa kuti utoto ukhale wabwino.
Mankhwala opangira
Ndizopangira zopangira mankhwala monga oxalates ndi oxalates, ndipo amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, pulasitiki ndi ena.
III. Kafukufuku wa Laboratory ndi Sayansi
1. Analytical chemistry
Oxalic acid angagwiritsidwe ntchito ngati chochepetsera pakuyesa kwa titration
2 Kukonzekera mayankho a buffer.
Kusakaniza ndi ma asidi ena kapena mchere, sinthani pH ya dongosolo loyesera.
Kusamalitsa
1. Oxalic acidimakwiyitsa khungu ndi mucous nembanemba. Valani magolovesi ndi magalasi pamene mukukumana
Zosungirako 3.
Iyenera kusindikizidwa ndi kusungidwa pamalo ozizira ndi owuma kuti isakhudzidwe ndi ma okosijeni amphamvu.
