Nā hopena maʻamau a me ka hoʻohana ʻana i ka waika oxalic a me ka noiʻi hihia o 100 tons o ka hoʻouna ʻana i ka waikawa oxalic

ʻOxalic acid he kemika maʻamau. I kēia lā, loaʻa iā Aojin Chemical he 100 tons oxalic acid, i hoʻouka ʻia a hoʻouna ʻia.
ʻO wai nā mea kūʻai e kūʻai aku i ka waika oxalic? He aha nā hoʻohana maʻamau o ka waika oxalic? Kaʻana like ʻo Aojin Chemical i nā hopena maʻamau a me ka hoʻohana ʻana i ka waika oxalic me ʻoe. ʻO ka pauka oxalic acid he mea hoʻohuihui, hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka ʻoihana, ka nānā ʻana i ka lab, ka hana metala a me nā māla ʻē aʻe. He ʻakika ikaika kona a hiki ke hoʻoheheʻe i ka ʻōpala a me ka unahi calcium.
I. Nā hana nui a me nā hoʻohana
1. Hoʻomaʻemaʻe a hoʻomaʻemaʻe
Hoʻohana ʻia ia e wehe i ka ʻōpala a me ka unahi ma ka ʻili o nā seramika, nā pōhaku a me nā metala, kūpono loa no ka mālama ʻana i nā waihona wai paʻakikī e like me nā lumi ʻauʻau a me nā paipu.
Hiki ke hoʻohana ʻia ma ke ʻano he bleaching agent no ka wehe ʻana i nā waihona puaʻa mai ka lole a i ʻole ka lāʻau, akā pono e hoʻomalu ʻia ka manaʻo e pale i ka corrosion.
