He aha ngā painga o te kapia epoxy bisphenol A?
Ko te kapia epoxy Bisphenol A BPA te momo kapia epoxy e tino hangaia ana, e whakamahia whānuitia ana hoki. He tino mārama, ā, ka hangaia mai i te bisphenol A BPA me te epichlorohydrin i te aroaro o te hauwai konutai. Ko te taumata o te polymerization, e tohuhia ana ko "n", kei waenganui i te 0 ki te 25. I runga i te taumaha ngota, ka taea te whakarōpū i ngā kapia epoxy ki ngā taumata rerekē. I te nuinga o te wā, ko te uara "n" toharite o ngā kapia epoxy taumaha ngota iti he iti iho i te 2 me te ira whakangawari i raro iho i te 50°C, ā, e kiia ana ko ngā kapia epoxy ngohengohe. Ko ngā kapia taumaha ngota waenga he uara "n" i waenga i te 2 me te 5, me te ira whakangawari mai i te 50°C ki te 95°C. Ko ngā kapia he uara "n" nui atu i te 5 (ira whakangawari i runga ake i te 100°C) ka whakarōpūtia hei kapia taumaha ngota teitei.
