Ni izihe nyungu za bisphenol A epoxy resin?
Bisphenol A BPA epoxy resin ni yo resin ya epoxy ikorwa cyane kandi ikoreshwa cyane. Igaragaza ubwiza bwinshi kandi ikorwa muri bisphenol A BPA na epichlorohydrin iyo hari sodium hydroxide. Igipimo cya polymerization, kivugwa nka "n", ubusanzwe kiri hagati ya 0 na 25. Hashingiwe ku buremere bwa molekile, resin za epoxy zishobora gushyirwa mu byiciro bitandukanye. Muri rusange, resin za epoxy zifite uburemere buke bwa molekile zifite agaciro ka "n" kari munsi ya 2 n'agace koroshya kari munsi ya 50°C, kandi zitwa resin za epoxy zoroshye. Resin zifite uburemere buciriritse bwa molekile zifite agaciro ka "n" hagati ya 2 na 5, aho zoroshya kari hagati ya 50°C na 95°C. Resin zifite agaciro ka "n" kari hejuru ya 5 (agace koroshya kari hejuru ya 100°C) zishyirwa mu gace ka molekile zifite uburemere bwinshi bwa molekile.
