Unsaturated polyester resin ke mofuta o sebelisoang haholo oa thermosetting resin, eo hangata e leng motsoako oa polymer o nang le libonto tsa ester le libonto tse habeli tse entsoeng ke condensation ea unsaturated dicarboxylic acid le diol kapa saturated dicarboxylic acid e nang le li-unsaturated diols. Hangata, karabelo ea poliester condensation e etsoa ho 190-220 ℃ ho fihlela boleng ba acid e lebelletsoeng (kapa viscosity) bo fihlelleha. Kamora hore polyester condensation reaction e phetheloe, palo e itseng ea vinyl monomer e eketsoa ha e ntse e chesa ho lokisa mokelikeli oa viscous. Tharollo ena ea polymer e bitsoa unsaturated polyester resin.
Unsaturated polyester resin e fihletse katleho e kholo mafapheng a mangata a indasteri, joalo ka tlhahiso ea ho palama moea le li-yacht lipapaling tsa metsing. Polymer ena esale e le mokokotlo oa phetoho ea 'nete indastering ea kaho ea likepe, kaha e ka fana ka ts'ebetso e ntle haholo le maemo a phahameng haholo a ts'ebeliso.
Li-resin tsa polyester tsa unsaturated le tsona li sebelisoa hangata indastering ea likoloi ka lebaka la moralo oa tsona o fapaneng, boima bo bobebe, litšenyehelo tse tlase tsa sistimi le matla a tlase a mochini.
Thepa ena e boetse e sebelisoa mehahong, haholo-holo ha ho etsoa liphaephe, litofo, lithaele tsa marulelo, lisebelisoa tsa ho hlapela, hammoho le liphaephe le litanka tsa metsi.
Lisebelisoa tsa resin ea unsaturated polyester li fapane. Li-resin tsa polyester ha e le hantle li emela e 'ngoe ea tse phethahetseng
metsoako e sebelisoang mefuteng e mengata ea liindasteri. Tse bohlokoa ka ho fetisisa, hammoho le tse bontšitsoeng ka holimo, ke:
* Lisebelisoa tse kopantsoeng
* Lipente tsa lehong
* Liphanele tsa laminated tse sephara, liphanele tsa masenke, liphanele tse nang le likhopo
* Seaparo sa gel bakeng sa likepe, likoloi le lisebelisoa tsa ho hlapela
* Ho kenya mebala, li-filler, li-stucco, li-putty le li-anchoring tsa lik'hemik'hale
* Lisebelisoa tse kopaneng tse itimang
* Quartz, 'mabole le samente ea maiketsetso
