Yiziphi izinzuzo ze-bisphenol A epoxy resin?
I-Bisphenol A BPA epoxy resin uhlobo lwe-epoxy resin olukhiqizwa kakhulu nolusetshenziswa kabanzi. Ibonisa ukucaca okuphezulu futhi yenziwe nge-bisphenol A BPA kanye ne-epichlorohydrin lapho kukhona i-sodium hydroxide. Izinga le-polymerization, elibizwa ngokuthi "n", livame ukusuka ku-0 kuya ku-25. Ngokusekelwe esisindweni sama-molecule, ama-epoxy resin angahlukaniswa ngama-grade ahlukahlukene. Ngokuvamile, ama-epoxy resin anesisindo sama-molecule aphansi anenani elimaphakathi "n" elingaphansi kuka-2 kanye nephuzu lokuthambisa elingaphansi kuka-50°C, futhi abizwa ngokuthi ama-soft epoxy resin. Ama-medium weight molecular resin anenani "n" eliphakathi kuka-2 no-5, nephuzu lokuthambisa eliphakathi kuka-50°C kuya ku-95°C. Ama-resin anenani "n" elingaphezu kuka-5 (iphuzu lokuthambisa elingaphezu kuka-100°C) ahlukaniswa njengama-high weight molecular resin.
