Cia's saib seb yuav tswj qhov kub li cas. Rau ib lub tswv yim, peb kho thiab txiav txim raws li qhov xwm txheej ntawm cov khoom. Yog tias tsis muaj cov khoom siv ntxiv, qhov kub yuav tsum siab tshaj 150 degrees, thiab lub sijhawm yuav ntev heev. Cia kuv qhia koj ib qho kev paub, koj puas paub tias lub thermoplastic yog dab tsi? Nws yog lub ntsiab lus ntawm melting point, feem ntau yog hais txog qhov kub thiab txias; Qhov kub ntawm lub xeev siab elastic thiab iav lub xeev ntawm thermosetting polymer cov ntaub ntawv hloov pauv hloov pauv hloov iav, uas feem ntau yog ntau yam ntawm cov yas thiab kub yaj crystallization kub, txias crystallization kub, sib txawv kub, thiab lwm yam.
Daim ntawv thov ntawm cov tshuab kos duab hlau yuav dhau los ua ntau dua, yog li peb yuav tsum muaj kev nkag siab tob txog nws. Tsuas yog nrog kev nkag siab ntau ntxiv tuaj yeem ua tiav kev ua haujlwm zoo thiab siv tau, thiab peb tuaj yeem daws teeb meem sai dua thaum peb ntsib teeb meem.
