He Tirohanga Whānui mō te Hua o te Waikawa Oxalic
Ko te waikawa oxalic, e mōhiotia ana ko te waikawa ethanedioic, ko te waikawa dicarboxylic māmā rawa atu me te tātai ngota (COOH) 2 ⋅2H2O
He rite ki ngā tioata poupou kore tae, ā, he wāhanga noa i roto i ngā tipu otaota, ko te nuinga kei roto i te āhua o te pāhare pāporo, te tote konupūmā rānei, engari ka kitea hei waikawa kore utu i roto i ngā tipu pērā i te pāpaka Hainamana me te panana. He iti noa te waikawa oxalic kei roto i te mimi tangata, ā, ko te konupūmā oxalate te wāhanga matua o ngā kōhatu mimi. Ina werahia ki te 100.1 °C, ka ngaro te wai tioata o ngā tioata waikawa oxalic hei hanga i te waikawa oxalic kore wai, ko tōna ira rewa he 189.5 °C. Ka wairewa te waikawa oxalic kore wai ki te wai, ki te etanoru rānei engari kāore e wairewa ki te etera. I roto i te taiwhanga, ka taea te wetewete i te waikawa oxalic mā te wera hei whakaputa i te hau hauota waro.
He rauemi matū nui te waikawa oxalic, he whānuitia ngā whakamahinga, ā, e whakamahia ana i roto i ngā mara maha. I te whanaketanga o ngā ahumahi rongoā, tae, me te paninga, me te whakatuwheratanga o te mākete o te ao, he mea tino tika te rangahau me te whakawhanake i te hanga waikawa oxalic.

Shandong Pulisi Chemical Co., Ltd. – Kōtaha Waikawa Oxalic
Ko Shandong Pulisi Chemical Co., Ltd., i whakatūria i te Oketopa 2006, ā, kei Zibo, Shandong tōna tari matua, he kaiwhakarato ngaio matua o ngā rauemi mata matū kounga teitei me te tapuwae puta noa i te ao. I runga i te u ki te rapunga whakaaro o te "arotahi ki te whakawhanake i ngā matū kounga", kua whanake te kamupene hei hinonga whānui e whakauru ana i te R&D, te whakaputa, te hokohoko me te kawe waka, me ngā hinonga hono tae atu ki a Zibo Anhao Chemical Co., Ltd. me China Changrui Co., Limited.
Ko tā mātou waikawa oxalic (CAS Nama: 144-62-7 mō te waikore, 6153-56-6 mō te waikore) he hua matua, i hangaia kia tutuki ai ngā paerewa kounga o te ao. E wātea ana i roto i ngā taumata ahumahi (te parakore ≥96%) me te taumata parakore (te parakore ≥99.6%), kei te noho tā mātou waikawa oxalic hei tioata mārama kore tae (te nuinga he waikore) me te tātai ngota C₂H₂O₄·2H₂O me te taumaha ngota o te 126.07. He tino wairewa ki te wai me te etanoru, he kaha ngā āhuatanga whakaiti, me te waikawa teitei—ko tētahi o ngā waikawa dicarboxylic waro kaha rawa atu.
He tino kaha te whakahaere i te kounga kia tutuki ai ngā paerewa ISO 9001:2015, ā, kua whakamanahia hoki e ngā whakahaere mana pēnei i a German BV, e whakamahia whānuitia ana tā mātou waikawa oxalic puta noa i ngā ahumahi maha:
Te Hangarau Whakarewa: He taputapu whai hua hei tango waikura, hei horoi me te whakapūmau i te rino, te parahi me ētahi atu whakarewa.
Hanganga: Rauemi mata matua mō ngā ranunga raima me te tukatuka rauemi hanga.
Ahumahi hiako: Whakamahia mō te whakama, te tango hinu me te whakakoi kiri i te hiako.
Te maimoatanga wai: He mea whakapūmau hei whakapai ake i te kounga o te wai me te tango unahi.
Kakahu me te tānga: Kaiwhakamā me te āwhina tae.
Ngā ahumahi rongoā me te kai: Whakamahia ki te hanga i ngā takawaenga rongoā me te tukatuka i ngā tāpiringa kai.
Me ngā whare putunga motuhake i Qingdao, Tianjin, ngā tauranga o Shanghai me te Rohe Hokohoko Koreutu o Zibo, ka whakarite mātou i te tuku pai ki ngā kiritaki o te ao. Kua paahitia e ā mātou hua ngā tiwhikete REACH, FAMI-QS me SGS, ā, ka kaweake ki neke atu i te 100 whenua me ngā rohe i Ūropi, Amerika, Āhia ki te Tonga-mā-rāwhiti, te Waenganui Rawhiti me Āhia ki te Waenganui. Kua whakatūria e mātou he hononga mahi tahi pumau mo te wā roa me ngā umanga rongonui tae atu ki a PetroChina, CNOOC, Saint-Gobain me Lafarge.
I Shandong Pulisi Chemical, ko te kounga, te haumaru me te ratonga e aro ana ki te kiritaki te kaupapa matua, me te whakarato i ngā otinga waikawa oxalic kua whakaritea kia tutuki ai ngā hiahia ahumahi kanorau o te ao.
