Nā Hoʻohana ʻana o ka ʻakika Oxalic i ka Paʻi ʻana a me ka Hoʻoluʻu ʻana i nā lole
I ka ʻoihana kemika, hoʻohana ʻia ka waikawa oxalic e hana i ka pentaerythritol, cobalt oxalate, nickel oxalate, basic fuchsin, nā pahu reagent piha no ka loiloi kila a me ka lepo, nā reagents kemika, a me nā huahana ʻē aʻe.
I nā kaʻina hana hoʻoluʻu wikiwiki, hana ia ma ke ʻano he mea hoʻomohala kala a hoʻopololei i ka ʻili.
He mea hoʻokeʻokeʻo ia no nā huahana mauʻu a me ka palaoa (e hoʻohana ana i nā waiwai hoʻēmi o ka waikawa oxalic) a ma ke ʻano he mea wehe i nā ʻōpala popo (hana ka waikawa oxalic me ka hao e hana i ka hao oxalate hiki ke hoʻoheheʻe ʻia, kahi e holoi maʻalahi ʻia me ka wai, a pēlā e wehe ai i nā ʻōpala hao mai nā lole).
Nā Hoʻohana ʻana o ka ʻakika Oxalic i ka Paʻi ʻana a me ka Hoʻoluʻu ʻana i nā lole
(1) Ke wehe ʻana i nā ʻōpala popo mai nā lole
Ke hōʻike ʻia ka hao i ka oxygen a me ka makū i ka lewa, hana ia i kahi hui paʻakikī i kapa ʻia ʻo ka popo. ʻOiai ke ʻano like ʻole o ka haku mele ma muli o nā kūlana hoʻokumu ʻana, aia nā popo āpau i nā iona hao trivalent. Hoʻokumu nā ʻili popo ma nā lole pulupulu i nā kīnā mau loa e pono e wehe ʻia, a he mea kūpono ka waikawa oxalic no ka hoʻopau ʻana iā lākou. ʻO ke kumumanaʻo, hana ka waikawa oxalic me nā iona hao trivalent (Fe³⁺) e hana i kahi ion hui anionic soluble, [Fe(C₂O₄)₃]³⁻, kahi e maʻalahi ke hoʻoheheʻe ʻia i ka wai. ʻO ka hoʻohana maʻamau he 20 g/L o ka waikawa oxalic me kahi 30 mL/L o 98% waikawa acetic.
Hoʻomaopopo Koʻikoʻi: Hiki i ka waikawa oxalic ke hōʻino i nā olonā. Ma hope o ka mālama ʻana, pono e holoi pono ʻia nā lole pulupulu me ka wai maʻemaʻe e wehe i nā koena o ka waikawa oxalic. Inā ʻaʻole holoi pono ʻia, e hoʻopili ʻia ka waikawa oxalic i hoʻoheheʻe ʻia i ka wā e maloʻo ai, e hōʻino nui ana i ka olonā a hana i nā lua.
Hiki i ka waikawa Oxalic ke wehe i nā ʻili popo mai nā lole nylon, kahi e hoʻoulu ai i ka melemele.
(2) Ke hoʻopau ʻana i ke kinoea waikawa nitrous i ka wā e hoʻomohala ana me nā kala Ingrain
I ka hoʻohana ʻana i ke ʻano sodium nitrite no ka paʻi pololei ʻana me nā dyes ingrain me nā dyes naphthol, hoʻopuka ʻia ka waikawa nitrous i ka wā o ka ulu ʻana o ka waikawa sulfuric. ʻO kēia ke kumu o ka paʻakai sodium naphthol AS ma ka lole e hana i nā precipitates ʻulaʻula-ʻeleʻele, e hopena ana i nā ʻili keʻokeʻo like ʻole. No ka hoʻopau ʻana i ka waikawa nitrous, hoʻohui ʻia kekahi manawa 1-2 g/L o ka waikawa oxalic i ka hopena ulu waikawa sulfuric ma ke ʻano he mea hoʻemi (e pani ana i ka waikawa formic, urea, a i ʻole sulfur). Hoʻemi ka waikawa oxalic i ka waikawa nitrous i ke kinoea nitrogen, e pale ana iā HNO₂ mai ka pane ʻana me AS e hana i nā hui brown.
Hāʻawi ʻo Zibo Anhao Chemical Co., Ltd. i ka Oxalic Acid kiʻekiʻe (Ethanedioic Acid, CAS 144-62-7) i hana ʻia no ka hilinaʻi ʻoihana a me ka hana mau. Loaʻa kā mākou waikawa oxalic ma ke ʻano he pauka kristal keʻokeʻo a i ʻole nā kristal moakaka kala ʻole, me ka maʻemaʻe ≥99.6%, ka makū haʻahaʻa, a me nā haumia liʻiliʻi, e hōʻoiaʻiʻo ana i nā hopena hilinaʻi ma nā noi āpau.
Hana ʻia no ka maʻalahi o ka hoʻohana ʻana, ʻoi aku ka maikaʻi ma ka hoʻomaʻemaʻe ʻana i ka ʻili metala, ka hoʻoluʻu ʻana a me ka hoʻokeʻokeʻo ʻana i nā lole, ka ʻili ʻili, ka unuhi ʻana i ka honua laha ʻole, a me ka mālama ʻana i ka wai ʻino. Me nā waiwai hōʻemi a me ka chelating ikaika, hoʻopau pono ia i ka ʻōpala, nā unahi, a me nā ʻōpala me ke kākoʻo ʻana i ka hana kemika pololei.
Hana ʻia ma lalo o ka kaohi koʻikoʻi o ka maikaʻi a hōʻoia ʻia me SGS, BV, a me FAMI-QS, ua kūlike kā mākou waikawa oxalic i nā kūlana ʻoihana honua. Hāʻawi mākou i nā ʻōpala hiki ke hoʻololi ʻia—nā ʻeke 25kg, nā pahu 50kg, a me nā IBC nui—me ka lako paʻa a me nā logistics ʻoihana e kākoʻo i nā hui like ʻana ma ka honua holoʻokoʻa.E leka uila mai iā mākou no nā kauoha nui a i ʻole nā kikoʻī loea: info@anhaochemical.com
