Ngā Take Matua mō te Whakahaere i te Hanganga Bisphenol A
Mō te parakore o ngā rauemi mata, me tino tirotirohia te parakore o te phenol me te acetone, hei rauemi mata matua mō te hanga bisphenol A. Kaua te parakore o te phenol e iti iho i te 99.5%, ā, me neke atu i te 99% te parakore o te acetone. Mā ngā rauemi mata parakore teitei ka taea te whakaiti i te pokanoa o ngā poke ki te tauhohenga, ā, ka pai te haere o te tauhohenga.
He mea nui te whakahaere i te pāmahana tauhohenga. Ko te pāmahana tauhohenga whakapūpū kei waenganui i te 40 – 60°C. I roto i tēnei awhe pāmahana, ka taea e te tere tauhohenga me te whiriwhiringa hua te eke ki te taurite pai. Ko ngā pāmahana tino teitei, tino iti rānei ka pā ki te hua me te kounga o te bisphenol A BPA. Ko te mahi me te whiriwhiringa o te whakakōkī te whakatau i te ahunga tauhohenga. Ko ngā whakakōkī waikawa e whakamahia whānuitia ana pērā i te waikawa whanariki me whakatinana tika i tō rātou kukū me te horopeta. I te nuinga o te wā, ka rerekē te kukū o te waikawa whanariki i roto i tētahi awhe, ā, ko te horopeta he ōwehenga motuhake o te tapeke o ngā rauemi mata, kia pai ai te mahi a te whakakōkī. Ka pā hoki te pēhanga tauhohenga ki te hanga bisphenol A BPA. Ko te awhe pēhanga tika ko te 0.5 – 1.5 MPa. Ka āwhina te taiao pēhanga pumau ki te pupuri i te pumau o te pūnaha tauhohenga, ā, ka whakatairanga i te whakawhiti papatipu me te ahunga whakamua o te tauhohenga. E pā tika ana te ōwehenga rauemi ki te whai huatanga o te tauhohenga. Ko te ōwehenga molar o te phenol ki te acetone ka whakahaerehia i te 2.5 – 3.5:1. Mā te ōwehenga tika ka taea te āwhina i ngā rauemi mata kia tere te tauhohe, kia nui ake ai te putanga o te bisphenol A BPA, me te whakaiti i ngā hua taha.

Mā te whakarerekētanga Bisphenol A BPA e whakarei ake te kaha ā-pūkaha, te ātete ki te rakuraku me te kakahu, kia rite ai ki te aro atu ki ngā wero uaua.
