Unsaturated polyester resin, eyaziwa nangokuthi isifinyezo sesiNgisiI-UPR, i-polymer ewuketshezi ephrinteka kalula okuthi, uma seyelashiwe (ixhunywe nge-styrene, ngokusetshenziswa kwezinto ezithile, ama-peroxides aphilayo, okuthiwa ama-hardeners), egcina isimo esiqinile esithathwe esikhunjeni.Izinto ezitholakele zinamandla akhethekile nezici zokuqina.Izinhlayiya ze-polyester ezingafakwanga zisetshenziswa kakhulu ngokuhlanganiswa nezinto eziqinisayo ezifanaimicu yengilazi, enikeza ukuphila ku-FRP (isifinyezo esisuselwa esiNgisini), i-polyester eqiniswe ngemicu yengilazi, eyaziwa kangcono ngegama elithii-fiberglass.Kulokhu, i-polyester resin inomsebenzi we-array, ihambisa amandla asetshenziswa kuzinto ezibonakalayo emicu eklanyelwe ukumelana nalawa mandla, ukwandisa amandla nokugwema ukuphuka komkhiqizo.Kanye noma ngokwehlukana nemicu yengilazi, uketsheziunsaturated polyester resiningase ilayishwe ngezimpushana noma ama-granules osayizi abahlukahlukene, anikeza imininingwane yokuqina nezici zokumelana, noma izimfanelo zobuhle ekulingiseni imabula yemvelo namatshe, ngezinye izikhathi kube nemiphumela engcono.Iunsaturated polyester resinisetshenziswa ngempumelelo enkulu emikhakheni eminingi yezimboni, njengasezindaweni zasemanzini ukuze kwakhiwe ama-windsurfers nezikebhe zokuzijabulisa.Lokhui-polymerbekuphakathi kwenguquko yangempela embonini yezikebhe, ngoba inganikeza ukusebenza okuhle nokuguquguquka okuphezulu kakhulu kokusetshenziswa.Iunsaturated polyester resinsnazo zivame ukusetshenziswa emkhakheni wezimoto (imboni yezimoto), ngenxa yokuguquguquka okukhulu kokuklama, isisindo esilula, izindleko zesistimu eziphansi namandla emishini.Le nto isetshenziselwa izakhiwo, ikakhulukazi ekwakhiweni kwama-hobs abapheki, amathayela ophahleni, izesekeli zamagumbi okugeza, kodwa namapayipi, imigudu namathangi.
I-POLYESTER ENGAGCINWE AMA-RESINS IZIMALI:
Izici eziyinhloko zezinhlayiya ze-polyester ezingasetshenzisiwe zihlanganisa: Uketshezi, ekusebenziseni kwabo:
● Ukuncipha komugqa okungekuhle.
● Ukumanzisa okuhle kakhulu kwamafayibha namashaji.
● Ukuxhumanisa okubandayo ngokuhlanganisa okokuqinisa.
● Ukunciphisa umthelela wokuhlehla ku-stratification eqondile (izakhiwo ze-thixotropic).
Okuqinile, ngemva kokuxhumanisa:
● Ukukhanya okungavamile.
● Ukuqina.
● Ukufakwa kahle kukagesi.
● Ukuzinza kwe-Dimensional ngokumelene nokushintsha kwezinga lokushisa.
● Isilinganiso samandla / isisindo esiphezulu kunensimbi.
● Ukungazweli amakhemikhali.
● Isiphetho esihle kakhulu sendawo.
● Ukuxosha amanzi.
● Ukumelana nokugqoka kanye namazinga okushisa aphezulu.
● Ukumelana okuhle kwemishini.
IZICELO ZOKUNCEDA I-POLYESTER ENGAFUTSHIWE:
Ukusetshenziswa kwe-polyester resin engasetshenzisiwe kuhlukahlukene.Ama-polyester resins empeleni amelela enye yezinhlanganisela eziphelele ezisetshenziswa ezinhlobonhlobo zezimboni.Okubaluleke kakhulu, kanye nalezo eziboniswe ngenhla, yilezi:
● Izinto eziyinhlanganisela.
● Opende bokhuni.
● Amaphaneli angama-flat laminated, amaphaneli kathayela, amaphaneli anezimbambo.
● Ijazi lejeli lezikebhe, izinto zezimoto nezokugezela.
● Ukufaka imibala kokunamathisela, okokugcwalisa, isituko, ama-putty namahange amakhemikhali.
● Izinto eziyinhlanganisela ezizicimayo.
● I-quartz, imabula kanye nosimende wokwenziwa.
