Melemo ea Epoxy Polyester Hybrids Coating Coating

Liaparo tsa phofo tsa epoxy tse thehiloeng ho theknoloji e ncha li tsejoa e le "hybrids" ea epoxy-polyester kapa "multipolymer". Sehlopha sena sa liphahlo tsa phofo se ka nkoa e le karolo ea lelapa la epoxy, ntle le hore karolo e phahameng ea polyester e sebelisoang (hangata e fetang halofo ea resin) e etsa hore sehlopha seo se khelose.
Thepa ea liphahlo tsena tse nyalisitsoeng li tšoana haholo le li-epoxies ho feta li-polyester, ntle le mekhelo e 'maloa e hlokomelehang. Li bonts'a ho feto-fetoha ha maemo ho ts'oanang le ts'usumetso le khanyetso ea ho koba, empa li hlahisa lifilimi tse bonolo hanyenyane.Ho hanyetsa ha bona ha kutu ho bapisoa le li-epoxies maemong a mangata, empa ho hanyetsa ha tsona ho solvents le alkali ke liphatsa tsa lefutso.rale tlase ho feta li-epoxies tse hloekileng.

Monyetla o mong oa li-hybrids tsena, ka lebaka la tšusumetso ea karolo ea polyester, ke ho hanyetsa ho hoholo ha 'mala o mosehla ka ontong ea pheko. Sena se boetse se fetolela ho hong ho ntlafetseng ho hanyetsang mahlaseli a mahlaseli a kotsi. Lisebelisoa tsena li tla qala ho chokoa ka potlako joaloka epoxy empa, ka mor'a ho chekoa ka lekhetlo la pele, ho senyeha ho lieha 'me ho fetoha ha mebala ho fokotsehile haholo ho feta bakeng sa phofo ea epoxy e sa fetoloang.

Molemo o mong oa ho roala phofo ea epoxy / polyester ke litšobotsi tsa bona tse ntle tsa electrostatic spray. Li ka sebelisoa ka katleho e ntle ea phetisetso 'me li bonts'a ho kenella hantle likhutlong le likheong.Lebasetere la polyester ea epoxy ka sebele le lokela ho nahanoa hammoho le lelapa la epoxy bakeng sa tšebeliso ea pheletso e tšesaane ea mokhabiso. Likopo tsa lebasetere la epoxy polyester li thathamisitsoe ho Setšoantšo sa 2-3; thepa e tloaelehileng e thathamisitsoe ho Figure 2-4.
