Cov thawv ntim yas tsis yooj yim kom tawg yog tias lawv muaj cov yam ntxwv hauv qab no:
1. Nws yog cov ua polymer sib txuas
2, nws tuaj yeem muaj nyob hauv ntau hom xws li cov khoom ua kua ua kua colloidal, thiab lwm yam.
3, nws tuaj yeem ua duab
4, ntau ntau yam sib txawv ntawm cov plastics, uas ua rau ntau lub plastics
5, ntau hom khoom lag luam muaj ntau yam khoom siv
6, nrog cov khoom sib txawv
7, tuaj yeem siv cov txheej txheem sib txawv
Cov thawv ntim cov yas yas muaj peev xwm muab faib ua ob hom: thermosetting thiab thermoplastic. Tus qub tsis tuaj yeem rov kho dua thiab tom kawg tuaj yeem tsim dua. Yeej muaj ob hom qauv yas polymer: qhov ib yog qauv txheej, polymer compound muaj cov qauv zoo li no hu ua linear polymer compound, thiab qhov thib ob yog cov qauv txheej txheem, thiab polymer compound muaj cov qauv zoo li no. hu ua bulk polymer compound. Qee cov polymers muaj ib txoj xov hu ua branched polymer, uas yog cov qauv linear. Qee cov polymers muaj qhov sib txuas-ntawm cov molecules, tab sis kev sib txuas sib txuas yog qhov tsawg dua. Nws yog hu ua cov qauv network thiab belongs rau lub cev qauv.
