ʻOihana maka waiwai
Oxalic acid C2H2O4 CAS: 144-62-7 ʻO ka hoʻomaʻemaʻe metala, ka hopena esterification catalyst, nā disinfectants polishing, cellulose
ʻIke kumu
ʻAno
1. Nānā: Paʻa kala kala ʻole, e hōʻike ana i ke ʻano aniani e like me ke kō
2. Solubility: He kiʻekiʻe ka solubility o ka waika oxalic i ka wai a hiki ke hana koke me ka wai e hana i ka hopena oxalic acid.
3. ʻAkika: ʻO ka ʻakika oxalic he ʻakika pālua e hiki ke hoʻokuʻu i ʻelua protons (H+) a hoʻopili me ke kumu e hana i ka paʻakai pili.
4. Oxidation: hiki ke hoʻohana ʻia ka ʻakika oxalic ma ke ʻano he mea hoʻohaʻahaʻa e hana me kekahi mau mea hoʻomake, e like me ka hydrogen peroxide (H2O2).
5. Decomposition: ma lalo o ka wela kiʻekiʻe a i ʻole nā kūlana waikawa ikaika, hiki ke hoʻoheheʻe ʻia ka waikawa oxalic i carbon dioxide (CO2) a me carbon monoxide (CO).
Hoʻohana
1. Mea hoʻomaʻemaʻe metala: hiki i ka oxalic acid ke hoʻopau i nā oxides, nā waihona alkali a me ka unahi ma ka metala, hoʻohana pinepine ʻia e hoʻomaʻemaʻe i nā mea metala, e like me ke kila kila, keleawe, aluminika, etc.
2. ʻO ka ʻoihana wai: hiki ke hoʻohana ʻia ka oxalic acid ma ke ʻano he waena no ka paʻi ʻana i ka wai a me ke kala, no ka hoʻohui ʻana i nā dyes a me nā puaʻa.
3. Catalyst: hiki ke hoʻohana ʻia ka waikawa oxalic e like me ka catalyst no kekahi mau hopena kemika, e like me ka esterification reaction, synthesis of carboxylate, etc.
4. Hoʻohana olakino a me ka lāʻau lapaʻau: hiki ke hoʻohana ʻia ka oxalic acid i mea hoʻomaʻemaʻe, disinfectant a me ka laxative. Hoʻohana ʻia i loko o kekahi mau lāʻau lapaʻau e mālama i kekahi mau pōhaku mimi.
5. ʻOihana uila: hiki ke hoʻohana ʻia ka oxalic acid e like me ka mea hoʻomaʻemaʻe a me ka polishing no nā mea uila.
6. ʻOihana lole: hiki ke hoʻohana ʻia ka oxalic acid ma ke ʻano he solvent no ka cellulose fibers, no ka hana ʻana o ka cellulose fibers.
7. Mea hoʻomaʻemaʻe: hiki ke hoʻohana ʻia ka oxalic acid ma ke ʻano he mea hoʻomaʻemaʻe, hiki ke hoʻoneʻe maikaʻi i ka papa oxide, stains a me ka unahi calcium ma ka ʻili metala. ʻO nā noi maʻamau ka hoʻomaʻemaʻe ʻana i nā mea kila kuhili ʻole a me ka hoʻomaʻemaʻe ʻana i nā halepaku a me nā ʻauʻau.
8. Ka pila: hiki ke hoʻohana ʻia ka waika oxalic e hana i nā pāpaʻi pālolo ferricyanide, nā pā hao a me nā aluminika a me kekahi mau pihi electrode dilute.
Paʻa
1.Oxalic acid kekahi mau meaʻawaʻawa, pono e hoʻolohe i ka hana palekana a me nā hana pale kūpono i ka wā e hoʻohana ai.
2. ʻO ka waika oxalic he corrosive, e ʻoluʻolu e hoʻolohe i ka palekana i ka wā e hoʻohana ai
3. He mea pōʻino ka ʻakika oxalic i ke kaiapuni a me ke olakino, a pono e hoʻohana pono a mālama pono ʻia
Ka waiho ʻana a me ka lawe ʻana
Waihona
1. E mālama i kahi maloʻo a maʻalili. Paʻa i ka moisture-proof, waterproof, and sun proof. ʻAʻole pono ka mahana mālama ma mua o 40 ℃.
2. E noho mamao mai ka oxides a me nā mea alkaline. Hoʻopili ʻia me nā ʻeke ulana polypropylene i hoʻopaʻa ʻia me nā ʻeke plastik.
Lawelawe
I ka wā o ka hoʻouna ʻana, pono e hoʻopaʻa ʻia ka pahu a pono e palekana ka hoʻouka ʻana. I ka wā o ka lawe ʻana, pono e hōʻoia ʻaʻole e kahe ka pahu, hāʻule, hāʻule a pōʻino paha. Pono e pale i ka ʻike ʻana i ka lā, ka wai ua, a me nā wela kiʻekiʻe i ka wā o ka lawe ʻana.
