ʻO ka hoʻohana ʻana i ka Polyester Epoxy Combined Chemistry no ka uhi ʻana o ka pauka UV

ʻO ka hui pū ʻana o ka polyester methacrylated a me ka resin epoxy acrylated e hāʻawi i kahi hui maikaʻi o nā waiwai i ke kiʻiʻoniʻoni hoʻōla. ʻO ka loaʻa ʻana o ka iwi kuamoʻo polyester ka hopena maikaʻi o ke kūpaʻa ʻana o nā pale i nā hoʻāʻo ʻino. Hāʻawi ka iwi kuamoʻo epoxy i ke kūpaʻa kemika koʻikoʻi, hoʻomaikaʻi i ka pili ʻana a me ka maʻalahi. ʻO kahi māhele mākeke maikaʻi no kēia UV ka uhi lepo he pani no ka PVC laminates ma nā panela MDF no ka ʻoihana lako.
Loaʻa ka hui polyester/epoxy i ʻehā mau ʻanuʻu nui.

1. ʻO ka polycondensation i ka heheʻe o kahi phthalic dicarboxylic acid derivative (PA) me kahi glycol e like me neopentyl glycol (PG) ma 240 °C ma ke alo o kahi catalyst esterification e like me butyl stannoic acid e hana i kahi polyester i hoʻopau ʻia i ka carboxy.
2. ʻO ka hoʻohui ʻana o ka glycidylmetacrylate (GMA) i ka polyester i hoʻopau ʻia i ka carboxy i hoʻoheheʻe ʻia ʻoiai e mālama ʻia ma lalo o 200 °C. Hoʻopili ʻia nā pūʻulu Methacrylate ma ka hope o nā kaulahao polyester e ka wikiwiki o ka hoʻohui ʻana "epoxy/carboxy". No nā kumu toxicological, ʻaʻole i hoʻohana ʻia ka glycidylacrylate. Hōʻalo ʻia ka gelation o nā paʻa pālua e ka hoʻohana ʻana i nā mea paʻa kūpono.
3. ʻO ka hoʻohui ʻana o ka ʻakika acrylic (AA) i kahi resin diepoxy i hoʻoheheʻe ʻia e hāʻawi i kahi polymer epoxy diacrylate.
4. Hoʻohui like ʻia ka polyester methacrylated a me ka resin epoxy acrylated e ka extrusion.
