Cov txheej txheem ntawm txhaj tshuaj molding yog (yas nplaum) rau (ntws) rau (sib sau) rau (crystallization).
Yas,
Namely, lub xeev iav, lub tsho loj tshaj plaws (rubber lub xeev), lub xeev khov nquag (lub xeev yas), lub xeev lwj, raws li tau hais hauv daim duab:
Lub iav: 0 ~ T1, cov molecules yog khov, tawv thiab nkig, thiab yoojyim ua rau hauv siab.
Pom dav nquag hauv xeev (plasticized state): T2 ~ T3, tuaj yeem ua tiav thaum yuav.
Decomposition state: T3, lub hnab yas pib tawg, roj zuj zus, txawm lub xeev xwm txheej.
