He pēhea te whakahaere i te Tikanga Waikawa Sulfuric Bisphenol A BPA?
Bisphenol A bpa Tikanga Waikawa Whāriki
Ka pāngia te phenol me te acetone e te tauhohenga whakapūpū i roto i te waikawa whanariki me te kukū papatipu o te 72.5%–73.0% i te 35–45°C. Kātahi ka horoia te hua ki te wai, ka whakakōkītia, ka wehea mā te centrifugation, ā, ka whakamarokehia kia whiwhi ai i te bisphenol A e tika ana mō ngā kapia epoxy whānui me ngā aukati mura. Ko te reiti kai mō ia tana o te hua he tata ki te 0.925 tana o te phenol, 0.285 tana o te acetone, me te 0.500 tana o te waikawa whanariki (98% te parakore).
He tino māmā ngā taputapu me ngā tukanga o tēnei tikanga Bisphenol A bpa. Heoi, he nui ngā rauemi mata e pau ana, ā, ka piki ake ngā utu hua. Ka waikura hoki ngā taputapu, ngā paipa, ngā takirere, me te wāhi whakaputa, ā, ka nui hoki ngā para e puta mai ana. Heoi anō, kāore te kounga o te hua e tutuki i ngā whakaritenga mō te hanga polycarbonate, ngā kapia epoxy rānei.
