Ngā Whakamahinga o te Waikawa Oxalic i roto i te Tānga me te Tae Kakahu
I roto i te umanga matū, ka whakamahia te waikawa oxalic ki te hanga pentaerythritol, cobalt oxalate, nickel oxalate, basic fuchsin, ngā kete matū katoa mō te tātari maitai me te oneone, ngā matū matū, me ētahi atu hua.
I roto i ngā tukanga tae tere, ka mahi ia hei kaiwhakawhanake tae me te whakataurite.
He mea whakamakuku tēnei mō ngā hua kakau witi me te kakau witi (e whakamahi ana i ngā āhuatanga whakaiti o te waikawa oxalic) me te tango paru waikura (ka tauhohe te waikawa oxalic ki te rino hei hanga i te oxalate rino wairewa, ka ngāwari te horoi atu ki te wai, ā, ka tangohia ngā paru rino i ngā kakahu).
Ngā Whakamahinga o te Waikawa Oxalic i roto i te Tānga me te Tae Kakahu
(1) Te Tango i ngā Paraka Waikura mai i ngā Kakahu
Ina pāngia te rino e te hāora me te makuku o te rangi, ka puta he matū matatini e kiia nei ko te waikura. Ahakoa he rerekē te hanganga tuturu i runga i ngā āhuatanga hanganga, kei roto i te waikura katoa ngā iona rino trivalent. Ka puta he hapa tuturu i ngā paru waikura i runga i ngā kakahu miro me tango, ā, he mea whai hua te waikawa oxalic hei whakakore i aua mea. Ko te kaupapa matua ko te waikawa oxalic ka tauhohe ki ngā iona rino trivalent (Fe³⁺) hei hanga i tētahi iona matatini anionic wairewa, [Fe(C₂O₄)₃]³⁻, e ngāwari ana te wairewa ki te wai. Ko te whakamahinga noa ko te 20 g/L o te waikawa oxalic me te 30 mL/L o te 98% waikawa acetic.
He Tuhipoka Hira: Ka taea e te waikawa oxalic te kino i ngā muka. I muri i te maimoatanga, me horoi pai ngā kakahu miro ki te wai ma hei tango i ngā toenga waikawa oxalic katoa. Ki te kore e horoia tika, ka kukū te waikawa oxalic waimeha i te wā e maroke ana, ka nui te kino o te muka, ka hanga kōhao.
Ka taea hoki e te waikawa oxalic te tango i ngā paru waikura mai i ngā kakahu nairona, ki te kore ka puta te kōwhai.
(2) Te Whakakore i te Hau Waikawa Hauota i te Wā e Whakawhanakehia ana me ngā Tae Ingrain
Ina whakamahia te tikanga konutai nitrite mō te tā tika me ngā tae ingrain i te taha o ngā tae naphthol, ka puta te waikawa nitrous i te wā e whanake ana te waikawa whanariki. Mā tēnei ka puta he putunga parauri-whero i roto i ngā tote konutai naphthol AS i runga i te papanga, ka puta he whenua mā koretake. Hei whakakore i te waikawa nitrous, ka tāpirihia he 1–2 g/L o te waikawa oxalic ki te otinga whakawhanake waikawa whanariki hei kaiwhakaiti (hei whakakapi i te waikawa formic, urea, whanariki rānei). Ka whakaitihia e te waikawa oxalic te waikawa nitrous ki te hau hauota, ka ārai i te HNO₂ mai i te tauhohenga ki te AS hei hanga i ngā pūhui parauri.
Ka tukuna e Zibo Anhao Chemical Co., Ltd. te Waikawa Oxalic kounga teitei (Waikawa Ethanedioic, CAS 144-62-7) i hangaia mō te pono o te ahumahi me te mahi pumau. Kei te wātea tā mātou waikawa oxalic hei paura tioata ma, hei tioata mārama kore tae rānei, he ≥99.6% te parakore, he iti te makuku, he iti hoki ngā poke, e whakarite ana i ngā hua pono puta noa i ngā tono.
He mea hanga kia maha ngā whakamahinga, he tino pai mō te horoi i ngā mata whakarewa, te tae me te whakama i ngā kakahu, te whakamā i te kiri hiako, te tango i ngā mea onge, me te maimoatanga wai para. He kaha ōna āhuatanga whakaiti me te whakakōpiri, ā, ka tangohia pai te waikura, ngā unahi, me ngā paru, me te tautoko hoki i te tukatuka matū tika.
I hangaia i raro i te mana whakahaere kounga tino pakari, ā, i whaimanahia hoki e te SGS, BV, me te FAMI-QS, ka tutuki i tā mātou waikawa oxalic ngā paerewa ahumahi o te ao. Kei a mātou ngā takai ngāwari—ngā putea 25kg, ngā pahu 50kg, me ngā IBC papatipu—me te tuku pumau me ngā mahi whakahaere ngaio hei tautoko i ngā hononga mahi tahi o te ao.Whakapā mai ki a mātou mō ngā ota nui, ngā whakaritenga hangarau rānei: info@anhaochemical.com
