I-Liquid Unsaturated Polyester Resin Yekhwalithi Ephezulu Ye-Fiberglass
"I-Polyester" iyisigaba sama-polymer compounds aqukethe ama-ester bond ahlukile kuma-resin afana nama-phenolic nama-epoxy resin. Le polymer compound ikhiqizwa yi-polycondensation reaction phakathi kwe-dibasic acid kanye ne-dibasic alcohol, futhi uma le polymer compound iqukethe i-unsaturated double bond, ibizwa ngokuthi i-unsaturated polyester, futhi le polyester engasaturated incibilikiswa ku-monomer enekhono lokuba yi-polymerised (ngokuvamile i-styrene).
Le polyester engagcwali incibilikiswa ku-monomer (ngokuvamile i-styrene) enekhono loku-polymerize, futhi uma iba uketshezi oluqinile, ibizwa ngokuthi i-unsaturated polyester resin (i-Unsaturated Polyester Resin noma i-UPR ngamafuphi).
Ngakho-ke i-resin ye-polyester engagcwalisiwe ingachazwa njengoketshezi oluqinile olwakhiwe yi-polycondensation ye-dibasic acid ene-dibasic alcohol equkethe i-dibasic acid engagcwalisiwe noma i-dibasic alcohol ekwakhiweni kwe-polymer okuqondile okuncibilikiswe ku-monomer (ngokuvamile i-styrene). Ama-resin e-polyester angagcwalisiwe, akha amaphesenti angama-75 ama-resin esiwasebenzisa nsuku zonke.
