ʻAkika ʻokalika he kemika maʻamau. I kēia lā, loaʻa iā Aojin Chemical he 100 tons o ka waikawa oxalic, kahi i hoʻouka ʻia a hoʻouna ʻia.
ʻO wai nā mea kūʻai aku e kūʻai ana i ka waikawa oxalic? He aha nā hoʻohana maʻamau o ka waikawa oxalic? Ke kaʻana like nei ʻo Aojin Chemical i nā hopena maʻamau a me nā hoʻohana o ka waikawa oxalic me ʻoe. ʻO ka pauka waikawa oxalic kahi hui organik, i hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻoihana, ka nānā ʻana i ka hale hana, ka hana metala a me nā ʻoihana ʻē aʻe. Loaʻa iā ia ka acidity ikaika a hiki ke hoʻoheheʻe i ka popo a me ka unahi calcium.
I. Nā hana nui a me nā hoʻohana
1. Ka hoʻomaʻemaʻe a me ka wehe ʻana i nā unahi
Hoʻohana ʻia ia e wehe i ka ʻōpala a me ke unahi ma luna o ka ʻili o nā keramika, 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 mea hoʻokeʻokeʻo e wehe i nā waihona pigment mai nā lole a i ʻole ka lāʻau, akā pono e kaohi ʻia ka nui e pale aku i ka pala.
2. Nā noi ʻoihana a me nā noi keʻena hoʻokolohua
I ka ʻoihana kemika, hoʻohana ʻia e hoʻomākaukau i nā oxalates, dyes, nā mea hana lāʻau lapaʻau, a pēlā aku.
I loko o ka hale hana, hoʻohana ʻia ia ma ke ʻano he reagent analytical e ʻike ai i ka calcium a me nā ion metala honua kakaikahi, a i ʻole he mea hoʻemi e komo i nā hopena.
ʻAʻole hiki ke hoʻohana ʻia e hoʻomaʻemaʻe i nā huahana alumini a me ke keleawe, ka mea e hoʻonui ai i ka pala.
E pale i ka hui ʻana me ka bleach (e like me ka sodium hypochlorite)
Ka mālama ʻana a me ka lawelawe ʻana 3.
E mālama i loko o kahi pahu paʻa ma kahi anu, kahi mamao aku mai nā keiki a me ka meaʻai.
Pono e hoʻokaʻawale ʻia ka wai ʻōpala ma mua o ka hoʻokuʻu ʻana a ʻaʻole hiki ke ninini pololei ʻia i loko o ka ʻauwai.
Ka manawa hoʻouna: Iulai-16-2025
