I-polyester resin engagcwalisiwe iwuhlobo oluvame ukusetshenziswa kakhulu lwe-thermosetting resin, ngokuvamile okuyinhlanganisela ye-polymer eqondile enamabhondi e-ester namabhondi aphindwe kabili angagcwalisiwe akhiwa ukujiya kwe-dicarboxylic acid engagcwalisiwe enama-diol noma i-dicarboxylic acid egcwele ene-unsaturated diols.Ngokuvamile, ukusabela kwe-polyester condensation kwenziwa ku-190-220 ℃ kuze kube yilapho inani le-asidi elilindelekile (noma i-viscosity) lifinyelelwa.Ngemva kokuphothulwa kwe-polyester condensation reaction, inani elithile le-vinyl monomer liyengezwa ngenkathi kushisa ukuze kulungiswe uketshezi lwe-viscous.Lesi sixazululo se-polymer sibizwa nge-unsaturated polyester resin.
I-polyester resin engagcwalisiwe izuze impumelelo enkulu emikhakheni eminingi yezimboni, njengokwakhiwa kwama-windsurfing nama-yachts emidlalweni yasemanzini.Le polymer ibilokhu iwumgogodla wenguquko yeqiniso embonini yokwakha umkhumbi, njengoba inganikeza ukusebenza okuhle kakhulu kanye nokuguquguquka okuphezulu kakhulu ekusetshenzisweni.
Izinhlayiya ze-polyester ezingenalutho nazo zivame ukusetshenziswa embonini yezimoto ngenxa yokuguquguquka kwemiklamo yazo, isisindo esilula, izindleko eziphansi zesistimu, namandla aphansi emishini.
Le mpahla ibuye isetshenziswe ezakhiweni, ikakhulukazi ekwenzeni izinto zokupheka, izitofu, amathayela ophahleni, izesekeli zokugezela, kanye namapayipi namathangi amanzi.
Ukusetshenziswa kwe-polyester resin engasetshenzisiwe kuhlukahlukene.Ama-polyester resins empeleni amelela enye yezinto eziphelele
ama-compounds asetshenziswa ezinhlobonhlobo zezimboni.Okubaluleke kakhulu, kanye nalezo eziboniswe ngenhla, yilezi:
* Izinto ezihlanganisiwe
* Opende ngokhuni
* Amaphaneli angama-flat laminated, amaphaneli kathayela, amaphaneli anezimbambo
* Ijazi lejeli lezikebhe, izinto zezimoto nezokugezela
* Imibala yokunamathisela, izigcwalisi, i-stucco, ama-putty nama-anchoring amakhemikhali
* Izinto eziyinhlanganisela ezizicishayo
* I-Quartz, imabula kanye nosimende wokwenziwa
