Khoom rau thawv yas

Yas yog cov khoom hluavtaws lossis cov duab polymer tshiab ua cov khoom tseem ceeb. Tom qab ntxiv ntau hom tshuaj ntxiv, tom ib qho ntsuas kub thiab siab nrog ductility, txias yuav raug kho nws cov duab ntawm ib chav kawm ntawm cov ntaub ntawv. Natural los yog hluavtaws polymer reagent molecules nyob rau hauv lub xeev melting, thiab nyob ib ncig ntawm lub uniform muab faib ntawm auxiliary molecules txheej txheem hu ua plasticizing, tau hu tus txheej txheem hu ua tau plasticizing, tsis tau tsis tau, yog suav hais tias tsis yog plasticizing. Yas ntim yog ib qho ntawm plaub cov ntaub ntawv nyob rau hauv lub lag luam ntim: daim ntawv thiab cov ntawv sau cia nyiaj rau 30%, yas accounted rau 25%, hlau accounted rau 25%, iav accounted rau 15%.
