Amfani da Polyester Epoxy Haɗin Chemistry don Rufin Foda UV

Haɗin polyester methacrylated da acrylated epoxy resin yana ba da haɗakar kaddarorin ban sha'awa ga fim ɗin da aka warke. Kasancewar kashin baya na polyester yana haifar da kyakkyawan juriya na sutura a cikin gwaje-gwajen yanayi. Kashin baya na epoxy yana ba da juriya na sinadarai, ingantaccen mannewa da santsi. Kasuwa mai ban sha'awa ga waɗannan UV foda shine maye gurbin laminates na PVC akan bangarorin MDF don masana'antar kayan aiki.
Ana samun gauran polyester/epoxy a cikin manyan matakai guda huɗu.

1. Polycondensation a cikin narke na phthalic dicarboxylic acid derivative (PA) tare da glycol irin su neopentyl glycol (PG) a 240 ° C a gaban wani esterification mai kara kuzari kamar butyl stannoic acid don samar da polyester-karshen carboxy.
