Kaʻina Hana Hoʻomākaukau Kūlana ʻAkika Oxalic
Pono ke kaʻina hana hoʻomākaukau hopena e hahai pono i nā kaʻina hana kemika. ʻO ka mea mua, koho i nā ipu i hana ʻia me ka polyethylene kiʻekiʻe-density (HDPE), kahi e hāʻawi ai i ke kūpaʻa ʻoi aku ka maikaʻi o ka waikawa oxalic i hoʻohālikelike ʻia me nā plastics maʻamau. Hiki ke hoʻohana ʻia nā ipu aniani no ka manawa pōkole, akā hiki i ka mālama lōʻihi ke hana i ka sodium ion leaching, e hoʻopilikia ana i ke kūpaʻa o ka hopena.
I ka wā e hoʻomākaukau ai, e ana mau i ka nui o ka wai e pono ai ma mua, a laila e ninini mālie i ka waikawa oxalic i lalo ma ka ʻaoʻao o ka ipu. ʻAʻole pono e hoʻohuli ʻia kēia kauoha. Hōʻike nā hoʻokolohua ʻo ka hoʻohui ʻana i ka wai i ka waikawa i hoʻopaʻa ʻia e hoʻoulu ai i kahi hopena exothermic koke e hiki ana i 80–100°C, hiki ke alakaʻi maʻalahi i nā pōpilikia pīpī. ʻO ka hahai ʻana i ke kaʻina pololei e mālama i ka piʻi ʻana o ka mahana i loko o kahi pae palekana.
No ka hoʻoulu ʻana, e hoʻohana i kahi aniani a i ʻole polytetrafluoroethylene (PTFE) stir bar, a hoʻohui mau no 5-7 mau minuke a hiki i ka maopopo loa ʻana o ka hopena. E hoʻomaopopo he hana endothermic ka hoʻoheheʻe ʻana o ka waikawa oxalic. E ʻae i ka hopena i hoʻomākaukau ʻia e kū no 20-30 mau minuke e hiki ai i ke kaulike mahana o ka lumi, ma ia manawa e paʻa ai ka pH ma ka pae kūpono o 1.5-2.0.
ʻAkika Oxalic – Zibo Anhao Chemical Co., Ltd.
ʻO Zibo Anhao Chemical Co., Ltd. kahi mea hana hilinaʻi a me ka mea hoʻolako o ka waikawa oxalic maʻemaʻe kiʻekiʻe (ʻakika ethanedioic, CAS 144‑62‑7) me ke keʻena nui ma Zibo, Shandong, Kina. Loaʻa kā mākou waikawa oxalic ma nā ʻano anhydrous (C₂H₂O₄, MW 90.03) a me dihydrate (H₂C₂O₄·2H₂O, MW 126.07), me ka maʻemaʻe liʻiliʻi o 99.6%. ʻIke ʻia ia he mau kristal moakaka kala ʻole a i ʻole ka pauka kristal keʻokeʻo, ʻaʻohe ʻala, a hoʻoheheʻe nui ʻia i ka wai a me ka ethanol.
Hana ʻia ma lalo o ka kaohi koʻikoʻi o ka maikaʻi a me nā kaʻina hana i hōʻoia ʻia e ISO 9001, ua kūlike kā mākou waikawa oxalic me nā kūlana ʻoihana a me nā reagent-grade me nā haumia haʻahaʻa (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Ma ke ʻano he waikawa dicarboxylic a me ka mea hoʻemi, lawelawe ia ma ke ʻano he mea chelating koʻikoʻi, mea hoʻokeʻokeʻo, a me ka waena kemika. Hoʻohana nui ʻia i ka mālama ʻana i ka ʻili metala (wehe ʻana i ka popo, passivation), ka hoʻoluʻu ʻana a me ka paʻi ʻana i nā lole (mordant, bleach), ka ʻili ʻili, ka poli ʻana o ke kinikini, a me ka mālama ʻana i ka wai. He mea nui nō hoʻi ia no ka unuhi ʻana i nā mea honua kakaikahi, ka synthesis organik (oxalate salts/esters), nā waena lāʻau lapaʻau, a me nā ʻano huahana hoʻomaʻemaʻe.
Ma Anhao Chemical, hōʻoia mākou i ka lako paʻa, ka nānā pono ʻana i ka maikaʻi, a me ka hoʻopili maʻalahi: nā ʻeke 25kg, 500kg/1000kg FIBC, a me nā pahu ISO. Me nā makahiki he ʻumi o ka hana kemika a me ka ʻike hoʻokuʻu aku, hāʻawi mākou i ka waikawa oxalic i nā mea kūʻai aku ma Asia Hikina Hema, ʻEulopa, ka Hikina Waena, a ma ʻō aku, i kākoʻo ʻia e ke kākoʻo loea a me ka logistics kūpono. Ua kūpaʻa mākou i ka hāʻawi ʻana i nā hopena waikawa oxalic kiʻekiʻe a kūpono hoʻi i hoʻopilikino ʻia i kāu mau pono ʻoihana a me ke kālepa.
