Yini tinzuzo bisphenol A resin epoxy?
I-Bisphenoli A bpa i-epoxy resin nguyona ndlela lekhicitwa kakhulu futsi lesetjentiswa kakhulu ye-epoxy resin. Ikhombisa kucaca lokusetulu futsi ihlanganiswa kusuka ku bisphenol A BPA kanye ne epichlorohydrin lapho kune sodium hydroxide. Lizinga le-polymerization, lelikhonjiswa ngekutsi "n", livame kusuka ku-0 kuya ku-25.Kususelwa esisindvweni se-molecule, ema-resin e-epoxy angahlukaniswa abe ngemabanga lehlukahlukene. Ngalokuvamile, ema epoxy resin laphansi anesisindvo se molecule anesilinganiso se "n" lesingaphansi kwa 2 kanye nendzawo yekutsamba ngaphansi kwa 50°C, futsi abitwa ngekutsi ngema epoxy resin lathambile. Ema resin lasemkhatsini anesisindvo se molecule ane "n" emkhatsini wa 2 na 5, ngesikhatsi sekutsamba kusuka ku 50°C kuya ku 95°C. Ema resin lanenani le "n" lelikhulu kuna 5 (liphuzu lekutsamba ngetulu kwa 100°C) ahlukaniswe njengema resin lanesisindvo lesiphakeme se molecule.
