Ho na le mefuta e 'meli ea li-resin tse sebelisoang ho hlahisa metsoako: thermoset le thermoplastic. Li-resin tsa thermoset ke li-resin tse tloaelehileng haholo, empa li-resin tsa thermoplastic li ntse li fumana thahasello e ncha ka lebaka la tšebeliso e ntseng e eketseha ea metsoako.
Li-resin tsa Thermoset lia thatafala ka lebaka la mokhoa oa ho fola, o sebelisang mocheso ho etsa li-polymer tse hokahaneng haholo tse nang le litlamo tse thata tse sa qhibiliheng kapa tse sa keneng tse sa qhibiliheng ha li futhumatsoa. Ka lehlakoreng le leng, li-resin tsa Thermoplastic ke makala kapa liketane tsa li-monomer tse nolofatsang ha li futhumatsoa le ho tiea hang ha li pholile, e leng mokhoa o ka fetoloang o sa hlokeng khokahano ea lik'hemik'hale. Ka bokhutšoanyane, u ka qhibilihisa le ho fetola li-resin tsa thermoplastic, empa eseng li-resin tsa thermoset.
Thahasello ea metsoako ea thermoplastic e ntse e eketseha, haholo-holo indastering ea likoloi.
Melemo ea Li-resin tsa Thermosetting
Li-resin tsa thermoset tse kang epoxy kapa polyester li ratoa haholo tlhahisong ea metsoako ka lebaka la ho ba le viscosity e tlase le ho kenella hantle marang-rang a fiber. Kahoo hoa khoneha ho sebelisa likhoele tse ngata le ho eketsa matla a thepa e kopantsoeng e felileng.
Moloko oa morao-rao oa lifofane hangata o kenyelletsa likarolo tse kopaneng tse fetang 50%.
Nakong ea pultrusion, likhoele li qoelisoa ka har'a resin ea thermoset ebe li kenngoa ka har'a hlobo e futhumetseng. Ts'ebetso ena e kenya tšebetsong karabelo ea ho folisa e fetolang resin e boima bo tlase ba limolek'hule hore e be sebopeho se tiileng sa marang-rang a mahlakore a mararo seo likhoele li notleloang ho sona marang-rang ana a sa tsoa thehoa. Kaha boholo ba liketso tsa ho folisa ke tsa exothermic, liketso tsena li tsoela pele e le liketane, li nolofalletsa tlhahiso e kholo. Hang ha resin e se e tiile, sebopeho sa mahlakore a mararo se notlela likhoele sebakeng sa tsona 'me se fana ka matla le ho tiea ho motsoako.
