3. Te Tukanga Whakapūngao Methanol
Ko te whakapūngao waro o te methanol he tikanga hou mō te whakaputa waikawa propionic. Mā te whakamahi i te methanol hei rauemi mata, ka puta te tauhohenga i te aroaro o tētahi whakakorikori hei hanga i tētahi pūnaha takawaenga waro-ira e ahu mai ana i te methanol, kātahi ka waikurahia hei whakaputa waikawa propionic.
4. Te Tukanga Whakahāora Propylene
1. Te Whakarite Rauemi Mata
Ko ngā rauemi mata mō te whakapūngao propylene ko te propylene, te hau, me te wai. Ka riro mai te propylene i ngā whare hanga hinu, i ngā whare pakaru rānei, ko te hau ia ka riro mai i ngā wāhanga wehewehe hau.
2. Tukanga Tauhohenga
Te whakamahana-mua: Ka whakamahana-muahia motuhaketia te propylene me te hau ki ngā pāmahana e tika ana kia pai ai te haere o te tauhohenga.
Tauhohenga Whakakorikori: Ka whakaranua te propylene me te hau kua whakamahanahia, ā, ka tauhohe i te aroaro o tētahi whakakorikori. Ka puta tēnei mahi i raro i ngā āhuatanga pāmahana me te pēhanga teitei, i te nuinga o te wā i te 250–350°C me te 1–3 MPa.
Whakamatao: Ka whakamataohia te hua tauhohenga ki te pāmahana rūma mā te pouaka whakamatao hei tukatuka atu.
3. Te Wehenga me te Whakama
I muri i te tauhohenga, he nui ngā poke me ngā rauemi mata kāore i tauhohenga kei roto i te hua, e hiahia ana kia wehea, kia purea hoki:
Wehewehenga: Ka wehea te wai, te propylene kāore i tauhohe, me ētahi atu poke mai i te hua mā te whakamahi i ngā wehewehe.
Te Whakama: Ka purea te waikawa propionic kua wehea mā te whakatōtō, te tango, me ētahi atu tikanga hei whiwhi i te waikawa propionic tino parakore.

Waikawa Propionic – Shandong Pulisi Chemical Co., Ltd.           info@pulisichem.cn
He kaiwhakarato pono, he kaihanga hoki a Shandong Pulisi Chemical Co., Ltd. o te waikawa propionic tino parakore (CH₃CH₂COOH, CAS 79-09-4) i Haina, e tuku ana i ngā hua kounga teitei kua whakaritea mō ngā mahi ahumahi, kai, whāngai kararehe, me ngā mahi rongoā. Ko tā mātou waikawa propionic he wai kore tae, he waikura, he kakara kakara motuhake, he wairewa nui ki te wai me ngā whakarewa rauropi, ā, he rite tonu te kounga ki ngā paerewa o te ao.
I hangaia mā roto i ngā tukanga waikura matatau me te mana whakahaere kounga tino pakari, ka tutuki i tā mātou waikawa propionic ngā whakaritenga o te taumata ahumahi me te taumata kai, kia iti ai te poke me te pumau o te mahi. He mea tiaki matua, he mea ārai harore, he takawaenga matū hoki: e whakamahia whānuitia ana i roto i te tiaki kai (ngā kai tunutunu, ngā hua miraka), te rokiroki kai me te witi (te aukati i te tipu o te harore), te hanga tote propionate (konutai propionate, konupūmā propionate), me te hanga i ngā patu taru, ngā mea hanga kirihou, ngā kakara, me ngā takawaenga rongoā.
I Pulisi Chemical, ko te pumau o te hua, te haumaru, me te tuku pumau te mea nui ki a mātou. Ka tākaihia ā mātou waikawa propionic ki roto i ngā pūwero paerewa, i ngā tāke ISO rānei, me ngā kōwhiringa tuku ngāwari hei whakatutuki i ngā hiahia kanorau o ngā kiritaki o te ao. E tautokona ana e ngā tau maha o te wheako hanga matū me te tīma R&D ngaio, ka oati mātou i te kounga hua pumau, te utu whakataetae, me te tautoko hangarau whānui mō ngā hoa mahi o te ao.
