Isonga ryiza rya Liquid idahagije Polyester Resin ya Fiberglass
"Polyester" ni icyiciro cyibikoresho bya polymer birimo imiyoboro ya ester itandukanye nibisigara nka fenolike na epoxy resin. Uru ruganda rwa polymer rutangwa na polycondensation reaction hagati ya acide dibasic na alcool ya dibasic, kandi iyo iyi compound polymer irimo umurunga wa kabiri udahagije, byitwa polyester idahagije, kandi iyi polyester idahagije irashonga muri monomer ifite ubushobozi bwo kuba polymerisime ( muri rusange styrene).
Iyi polyester idahagije yashongeshejwe muri monomer (ubusanzwe styrene) ifite ubushobozi bwo gukora polymerise, kandi iyo ihindutse amazi ya viscous, yitwa polyester idahagije (Resinine polyester Resin cyangwa UPR mugihe gito).
Amababi ya polyester adahagije rero ashobora gusobanurwa nkamazi ya viscous yakozwe na polycondensation ya acide dibasic hamwe na alcool ya dibasic irimo aside ya dibasic idahagije cyangwa alcool ya dibasic mumurongo wa polymer wuzuye ushonga muri monomer (ubusanzwe styrene). Poliester idahagije, igizwe na 75 ku ijana by'ibisigazwa dukoresha buri munsi.
