Ndezvipi zvakanakira bisphenol A epoxy resin?
Bisphenol A BPA epoxy resin ndiyo inonyanya kugadzirwa uye inoshandiswa zvakanyanya ye epoxy resin. Inoratidza kujeka kwakanyanya uye inogadzirwa kubva ku bisphenol A BPA ne epichlorohydrin kana paine sodium hydroxide. Dhigirii repolymerization, rinoratidzwa se "n", rinowanzova pakati pe0 kusvika 25. Zvichienderana nehuremu hwemamorekuru, epoxy resin inogona kuiswa muzvikamu zvakasiyana. Kazhinji, ma epoxy resin ane huremu hwakaderera hwemamorekuru ane avhareji ye "n" kukosha iri pasi pe2 uye poindi yekunyorovesa iri pasi pe50°C, uye anonzi ma soft epoxy resin. Ma resin ane huremu hwepakati hwemamorekuru ane kukosha kwe "n" pakati pe2 ne5, nepoindi yekunyorovesa iri pakati pe50°C kusvika 95°C. Ma resin ane kukosha kwe "n" kupfuura 5 (poindi yekunyorovesa iri pamusoro pe100°C) akaiswa muboka rema resin ane huremu hwemamorekuru hwakakwira.
