Me aro ngā tikanga rokiroki mō te bisphenol A ki ngā whāinga matua o te "ārai i te pirau, te whakarite i te haumaru, me te karo i ngā pānga ki te taiao".

Ngā Whakamahinga o te Bisphenol A (BPA)

He rauemi mata nui te Bisphenol A (BPA) mō te hanga polycarbonates, epoxy resins, me ngā polyesters ātete pāmahana teitei. E whakamahia ana hoki hei whakaū PVC, hei ārai i te kirihou, hei mimiti UV, hei patu harore, me ētahi atu.
He matū maha-whakamahinga te BPA, ā, he whānuitia te whakamahinga i roto i te hanga kapia epoxy, polycarbonates, polyester resins, polyphenylene ether resins, me polysulfone resins. Hei tāpiri, he mea whakaū mō te polyvinyl chloride (PVC), he antioxidant i roto i ngā kirihou, he absorber UV, he harore harore ahuwhenua, me te kaihoko ārai-pakeke i roto i te rapa.
Ka whakamahia hoki hei ārai mate me te whakapūmau kirihou i roto i ngā peita me ngā waituhi. I roto i te hanga rauropi, ka mahi te BPA hei wāhanga matua mō te hanga kapia epoxy me te polycarbonate, ā, he whānuitia te whakamahinga hei rauemi mata nui mō ngā matū hanga ngota-teitei, tae atu ki ngā kaihoko ārai-pakeke, ngā whakapūmau kirihou, me ngā patu harore ahuwhenua.

Tauhohenga Matua
I raro i ngā āhuatanga whakakorikori waikawa, ka puta te tauhohenga hanga Bisphenol a BPA. He werawera te tauhohenga, ā, ko te wai te hua matua. Ka whakamahia e te tauhohenga te kapia whakawhiti kationa DOWEX hei whakakorikori. Ka whiwhihia tēnei whakakorikori i muri i te maimoatanga me te whakatairanga, ā, he tika te whiriwhiringa mō te hanga Bisphenol a BPA. He tino teitei te ōwehenga phenol/acetone i te wā o te tauhohenga, ā, ka mahia te tauhohenga i roto i te tauhohenga adiabatic.
Ka puta hoki i te tauhohenga ngā poke e whai ake nei:
OP-BPA
Trisphenol
Dihydroxydihydroanthracene
Ngā Pūhui Dianin
Ka tukuna te wai whaea ki te reflux hei whakataurite i te nui o ngā poke kia tino puta ai te PP-BPA i te tauhohenga matua. E rua ngā tauhohenga moenga-pūmau whakarara kei roto i te tipu, ko tētahi e whakamahia ana mō te tatari, mō te whakaora rānei. Ina iti rawa te mahi whakakorikori, ka tangohia tētahi tauhohenga mai i te raina whakaputa, ka tangohia te whakakorikori tawhito, ā, i mua i te whakaurunga anō ki te raina whakaputa, ka utaina he whakakorikori hou kua rongoatia ki te whakatairanga.
