Ukusetshenziswa kwe-Polyester Epoxy Combined Chemistry ye-UV Powder coating

Inhlanganisela ye-methacrylated polyester kanye ne-acrylated epoxy resin inikeza inhlanganisela ethakazelisayo yezakhiwo kufilimu eselashiwe. Ukuba khona komgogodla we-polyester kubangela ukumelana okuhle kwezingubo ekuhlolweni kwesimo sezulu. Umgogodla we-epoxy unikeza ukumelana kwamakhemikhali okuvelele, ukunamathela okuthuthukisiwe nokushelela. Ingxenye yemakethe ekhangayo yalezi UV i-powder coating ithatha indawo yama-laminate e-PVC kumaphaneli e-MDF embonini yefenisha.
Inhlanganisela ye-polyester/epoxy ifinyelelwa ngezinyathelo ezine ezinkulu.

1. I-polycondensation ekuncibilikeni kokuphuma kwe-phthalic dicarboxylic acid (PA) ene-glycol efana ne-neopenyl glycol (PG) ku-240 °C phambi kwe-esterification catalyst efana ne-butyl stannoic acid ukukhiqiza i-polyester enqanyuliwe nge-carboxy.
2. Ukwengezwa kwe-glycidylmethacrylate (GMA) ku-polyester encibilikisiwe ye-carboxy-terinated kuyilapho igcinwa ingaphansi kuka-200 °C. Amaqembu e-Methacrylate axhunyelelwa ekugcineni kwamaketanga e-polyester ngokusabela okusheshayo kokwengeza "i-epoxy/carboxy". Ngenxa yezizathu ezinobuthi, i-glycidylacrylate ayikaze isetshenziswe. I-Gelation yezibopho eziphindwe kabili igwenywa ngokusetshenziswa kwama-inhibitors afanelekile.
3. Ukwengezwa kwe-acrylic acid (AA) kunhlaka ye-diepoxy encibilikisiwe kuveza i-epoxy diacrylate polymer.
4. I-polyester ye-methacrylated kanye ne-acrylated epoxy resin kuhlanganiswe ngendlela efanayo nge-extrusion.
