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.

Te Hanganga Bisphenol a BPA e rua ngā taahiraa: Ko te nuinga o tēnei tukanga he whakamahi i ngā tote triphenylphosphine, i ngā tote ammonium quaternary rānei hei whakakorikori. Ka tāpirihia te Epichlorohydrin me te bisphenol A BPA ki te otinga, ā, ka whakanuia te pāmahana o te otinga ki te 120~130°C mō te tauhohenga. Muri iho, ka tāpirihia he otinga kawakore kaha, ā, ka whakaranua pai ki te 75~80°C mō te tauhohenga mowhiti-kati. I muri i te otinga o te tauhohenga, ka tangohia te epichlorohydrin taikaha mā te whakahoro, ka tāpirihia he whakarewa hei tango, ā, ka horoia te otinga tauhohenga ki te wai i ngā wā maha tae noa ki te koretake. Ka wehea te paparanga wai, ā, ka tangohia te whakarewa mā te whakahoro korehau hei whiwhi i te kapia epoxy Bisphenol a BPA.
