Bakelite yog ib qho piv txwv ntawm thermosetting polymer. Bakelite yog lwm lub npe ntawm Phenal formaldehyde. Nws yog cov thermosetting polymer vim nws muaj cov qauv sib txuas.
Qhov twg hauv qab no yog cov thermosetting resins Mcq?
Ua tiav cov lus teb ib kauj ruam:
Tam sim no Bakelite yog ib qho kev sib txuas ntawm cov polymer uas tom qab cua sov tsis tuaj yeem rov qab los ntawm nws cov qauv qub. Yog li nws yog ib qho thermosetting polymer. So tag nrho yog thermoplastic polymers. Thermoplastic polymers tuaj yeem faib ua amorphous lossis crystalline.
YPuas yog Bakelite yog thermosetting resin?
Bakelite muaj cov kab sib txuas, lossis cov saw hlau polymer hnyav heev. Bakelite polymer, thaum cua sov yog hardened thiab tsis tuaj yeem softened dua. Li no, nws yog thermosetting polymer.
