Intlaka yepolyester engafakwanga lolona didi lusetyenziswayo luqhelekileyo lwe-thermosetting resin, ngokuqhelekileyo i-linear polymer compound kunye ne-ester bonds kunye ne-unsaturated bonds ephindwe kabini eyenziwe yi-condensation ye-unsaturated dicarboxylic acid kunye ne-diols okanye i-dicarboxylic acid egcweleyo ene-unsaturated diols. Ngokuqhelekileyo, i-polyester condensation reaction iqhutyelwa kwi-190-220 ℃ de ixabiso elilindelekileyo le-asidi (okanye i-viscosity) lifikelelwe. Emva kokuba i-polyester condensation reaction igqityiwe, inani elithile le-vinyl monomer liyongezwa ngelixa lishushu ukulungiselela ulwelo lwe-viscous. Esi sisombululo sepolymer sibizwa ngokuba yi-unsaturated polyester resin.
I-resin ye-polyester engaxutywanga iphumelele impumelelo enkulu kwiinkalo ezininzi zemizi-mveliso, ezifana nokuveliswa kwe-windsurfing kunye neeyachts kwimidlalo yasemanzini. Le polymer ibisoloko ingundoqo kwinguqu yokwenyani kwishishini lokwakha iinqanawa, njengoko inokubonelela ngokusebenza okugqwesileyo kunye nokuguquguquka okuphezulu kakhulu ekusebenziseni.
Iinreyi zepolyester ezingafakwanga zikwasetyenziswa ngokuqhelekileyo kwishishini leemoto ngenxa yokuguquguquka koyilo, ubunzima bokukhanya, ixabiso eliphantsi lenkqubo, kunye namandla aphantsi oomatshini.
Esi sixhobo sikwasetyenziswa kwizakhiwo, ngakumbi ekwenziweni kwezinto zokupheka, izitovu, iithayile zophahla, izixhobo zokuhlambela, kunye nemibhobho kunye namatanki amanzi.
Ukusetyenziswa kwe-polyester resin engasetyenziswanga kuyahluka. I-polyester resins enyanisweni imele enye yezinto ezipheleleyo
iikhompawundi ezisetyenziswa kuluhlu olubanzi lwamashishini. Ezona zibalulekileyo, kunye nezi ziboniswe ngasentla, zezi:
* Izinto ezihlanganisiweyo
* Iipeyinti zokhuni
* Iiphaneli ezicandiweyo ezilaminethiweyo, iipaneli ezicandiweyo, iipaneli ezineembambo
* Idyasi yeGel yezikhephe, iimoto kunye nezixhobo zokuhlambela
* Ukufaka imibala kwintlama, izigcwalisi, istucco, iiputty kunye neeankile zeekhemikhali
* Izinto ezidibeneyo ezizicimayo
* Iquartz, ibhastile kunye nesamente eyenziweyo
