Polymers zoo haum rau kev txhaj tshuaj Molding

Feem ntau cov polymers yuav siv, nrog rau tag nrho cov thermoplastics thiab ib co elastomers. Muaj kaum tawm txhiab tus txawv cov ntaub ntawv muaj rau kev txhaj tshuaj molding. Cov ntaub ntawv uas tau muab sib tov nrog cov phom los yog cov khoom qub uas tau tsim los lawm txhais tau hais tias cov khoom tsim qauv yuav xaiv tau los ntawm ntau yam khoom xaiv los nrhiav tus uas muaj qhov tseeb. Cov ntaub ntawv raug xaiv raws li lub zog thiab kev ua haujlwm kom ua rau zaum kawg; tab sis ib qho kuj muaj ntau yam tsis zoo rau molding uas yuav tsum tau muab xam. Hom polymers zoo li nylon, polyethylene, thiab polystyrene yog thermoplastic.
