Tikanga Whakahāngai Waikawa Nitric Ethylene Glycol o te Waikawa Oxalic
He tino rite tēnei tukanga whakapūngao ki te tikanga whakapūngao māngaro. Ka whakamahanahia he otinga ethylene glycol wai ki te 60 °C, ā, ka tāpirihia te waikawa whakaranu (30%–40% waikawa whanariki mā te taumaha, 20%–25% waikawa hauota mā te taumaha) me te vanadium pentoxide me te whakaoho kaha. Ka mahia te whakapūngao i te 50–70 °C me te 1.3–4.0 kPa. Ka whakamataohia te hua, ka whakakōtitia, ka tātarihia kia whiwhi ai i te waikawa oxalic me te parakore o te 99.9% me te hua neke atu i te 90%. Ka taea te whakahaere i tēnei tikanga i raro i ngā āhuatanga tukanga e toru: te pēhanga hauātea, te pēhanga iti, me te pēhanga piki. He tukanga māmā, he nui te hua waikawa oxalic, he kounga hua pai, ā, tata tonu te whakaora i te waikawa hauota, engari he nui te utu mō ngā rauemi mata.

Shandong Pulisi Chemical Co., Ltd. Waikawa Oxalic Dihydrate – Parakore Taumata Ahumahi 99.6%
Ko Shandong Pulisi Chemical Co., Ltd., he kaihanga matū pono, he kaihokohoko hoki mai i te tau 2006, he tohunga ki te whakaputa waikawa oxalic dihydrate tino parakore (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) me te mana whakahaere kounga tino pakari. Ko te iti rawa o te parakore o tā mātou waikawa oxalic taumata ahumahi he 99.6%, ka puta he paura tioata ma me ngā taumata poke iti (sulfate ≤0.1%, konganuku taumaha ≤0.002%, rino ≤0.003%). He whānuitia te whakamahinga i roto i te tā me te tae kakahu, te tukatuka hiako, te horoi mata whakarewa, te whakakanapa māpere, te maimoatanga wai, te tango whenua onge, me te hanga takawaenga rongoā.
Kei te pupuri tonu mātou i te nui o ngā taonga kei roto i tō mātou whare putunga i Shandong, e āhei ai te tuku wawe i ngā ota nui. Mā ngā kōwhiringa takai ngāwari (25kg, 50kg, 1000kg putea) me te tuku ā-ao mai i ngā tauranga o Qingdao, Tianjin, Shanghai rānei ka taea te tuku i te wā tika puta noa i te ao. Ka whakaratohia e mātou he tautoko hangarau katoa, he tuhinga COA/MSDS, me ngā utu whakataetae hei whakatutuki i ngā hiahia ahumahi kanorau.
Whakapā mai ki a mātou i tēnei rā mō tētahi whakatau utu ritenga, kia mau ai tō mekameka tuku waikawa oxalic.
