Ngiziphi iinzuzo ze-bisphenol A epoxy resin?
I-Bisphenol A bpa i-epoxy resin mhlobo okhiqizwa khulu begodu osetjenziswa khulu we-epoxy resin. Itjengisa ukukhanya okukhulu begodu yenziwa nge-bisphenol A BPA kanye ne-epichlorohydrin lapho kune-sodium hydroxide. Izinga lokwenza i-polymerization, elivezwa ngokuthi "n", livamise ukusuka ku-0 ukuya ku-25. Ngokuya ngobunzima bamamolekhyuli, ama-epoxy resin angahlukaniswa ngamazinga ahlukahlukeneko. Ngokuvamileko, ama-epoxy resin anesisindo esiphasi anenani eliphakathi "n" elingaphasi kwe-2 kanye nephuzu lokuthambisa elingaphasi kwama-50°C, begodu abizwa ngokuthi ma-epoxy resin athambileko. Ama-resin wesisindo samamolekhyuli aphakathi nendawo anenani eliphakathi kwe-"n" hlangana no-2 no-5, ngephuzu lokuthambisa ukusuka ku-50°C ukuya ku-95°C. Ama-resin anenani le-"n" elingaphezu kuka-5 (iphuzu lokuthambisa elingaphezu kwe-100°C) ahlukaniswa njengama-resin anesisindo esiphezulu samamolekhyuli.
