He aha te rerekētanga i waenga i te waikawa oxalic me te Waikawa Acetic?
Hei wehewehe i te waikawa oxalic me te waikawa acetic, ka taea e tātou te whakarite i a rāua mai i ngā āhuatanga maha pēnei i te āhua matū, ngā āhuatanga, me ngā tono mahi. Ahakoa nō ngā waikawa rauropi e rua, ko ngā rerekētanga o ō rāua hanganga me ō rāua āhuatanga ka arahi ki ngā whanonga tino rerekē o te taiao, ngā tauhohenga matū, me te whakamahinga a te tangata.

Tuatahi, me titiro tātou ki ō rātou hanganga matū.
Ko te waikawa oxalic, e mōhiotia ana ko te waikawa ethanedioic, kei roto i tōna hanganga ngota e rua ngā rōpū carboxyl (-COOH), ko te tātai ngota H₂C₂O₄. He rite ki tētahi ngota e mau ana i ngā rōpū waikawa e rua, e rite ana ki te tuku i ngā katote hauwai e rua.

Ko te waikawa acetic, e mōhiotia ana ko te waikawa etanoic, he kotahi anake te rōpū carboxyl kei roto, ko te tātai ngota CH₃COOH. He rite tōna ngota ki te "haereere takitahi" me te rōpū waikawa kotahi. Ko tēnei rerekētanga o te hanganga ngota, he rite ki tā rātou "waehere ira", ka whakatau i te raupapa o ngā rerekētanga whanonga i muri mai.

Ko te whakaaturanga tino tika o tēnei "rerekētanga ira" ko te kaha o te waikawa.
He waikawa kaha takirua te waikawa oxalic ka taea te whakaionize i ngā katote hauwai i roto i te wairewa wai, ā, ka kaha ake tōna waikawa i tērā o te waikawa acetic.

He waikawa ngoikore monoprotic noa te waikawa acetic; ko ētahi o ōna ngota ka ionize i roto i te wai, ka hua ake he waikawa ngawari.
Ka taea e tātou te whakaaro ki te waikawa oxalic he rangatahi hihiko, tauhohe hoki, ko te waikawa acetic ia he rite ki te kaumātua ngāwari, mārire.

Mō ngā āhuatanga matū, nā te hononga tika o ōna rōpū carboxyl e rua, he kaha te whakaiti i te waikawa oxalic. Ka ngāwari te whakahāweatia e ngā matū whakahāwea (pērā i te pāhare pākawa) hei hanga i te hauhā waro me te wai. Nā tēnei āhuatanga e whakamahia whānuitia ai te waikawa oxalic hei matū whakaiti i roto i ngā tātaritanga matū.

He rerekē, he āhua pumau te hanganga ngota ngota o te waikawa acetic, kāore e ngāwari te waikura, ka hua ake he āhua matū "pūmau" ake.
Hei tāpiritanga, ina tauhohe te waikawa oxalic ki ētahi katote konganuku (pērā i ngā katote konupūmā), ka puta he putunga konupūmā oxalate kāore e wairewa pai ki te wai, ko tētahi o ngā wāhanga matua o ngā kohatu tākihi.
Hei whakataurite, ko ngā acetate i hangaia mā te tauhohenga o te waikawa acetic me ngā ion konupūmā me ētahi atu matū he ngāwari te wairewa ki te wai.

Mō te āhua o te putanga mai me te whakamahinga, he rerekē te arotahi o ia mea.
He nui te kitea o te waikawa oxalic i roto i ngā tipu maha o te taiao, pērā i te pīnihi, te amaranth, me te rhubarb. Koia te take e taunakihia ana kia whakamakukuhia ēnei huawhenua i mua i te kai hei tango i tētahi wāhanga o te waikawa oxalic. He whānuitia ana whakamahinga ahumahi, tae atu ki te tango waikura, te whakama i ngā kakahu, me te wehewehe me te purenga o ngā konganuku whenua onge. Heoi, nā te mea he paitini me te waikura, me tino tupato te whakamahi.

Ko te waikawa acetic tētahi o ngā waikawa rauropi tino mōhiotia i roto i te oranga o ia rā. Koinei te wāhanga matua o te winika, e homai ana ki te winika tōna reka kawa ahurei. I roto i te umanga kai, ka whakamahia te waikawa acetic hei waikawa me te tiaki; i roto i te umanga matū, he rauemi mata hanga rauropi nui mō te hanga vinyl acetate, ngā muka acetate, me ētahi atu. Nā tōna waikawa ngawari me te iti rawa o te paitini (i roto i ngā awhe kai whaitake), he whānui ake te whakamahinga me te haumaru o te waikawa acetic i roto i ngā mara kai me te rongoā.

Waikawa Oxalic – Zibo Anhao Chemical Co., Ltd.
He kaihanga pono a Zibo Anhao Chemical Co., Ltd. nō Haina, he kaiwhakarato hoki i te waikawa oxalic kounga teitei (Ethanedioic Acid, CAS 144-62-7), kei Zibo, Shandong te pūtake o te umanga matū o Haina. Kei te wātea mai tā mātou waikawa oxalic i roto i ngā momo kohakore (≥99.5%) me te dihydrate (≥99.0%), he rite ki te paura tioata ma me ngā āhuatanga matū pumau, he iti te makuku, ā, he iti noa ngā poke.

I hangaia i raro i te mana whakahaere kounga tino pakari me ngā paerewa ā-motu, he kaha te kaha whakaiti me te kaha whakapūmau pai o te waikawa oxalic, e whakamahia whānuitia ana i roto i te tae kakahu (mordant/bleaching), te maimoatanga whakarewa (tango waikura/whakakikorua hiko), te tango whenua onge, te hanga rauropi, te whakakoi hiako, me te hanga rongoā me te ahuwhenua. Kua whakamatautauria katoatia ia puranga, ā, kei roto i te COA, MSDS, me ētahi atu tuhinga ture hei whakatutuki i ngā hiahia ahumahi o te ao.

He maha ngā tau o te wheako kaweake puta noa i Āhia, i Ūropi, i te Waenganui Rawhiti, me tua atu, e tuku ana mātou i ngā takai ngāwari (pēke 25kg), he utu whakataetae, me ngā tikanga tuku pono (FOB/CIF/DDP). Ahakoa he iti noa ngā ota whakamātautau, he nui rānei te tuku, ka tukuna e Zibo Anhao Chemical te kounga pumau, te tuku pumau, me ngā otinga kua whakaritea hei tautoko i te tipu o tō pakihi.
