Molecular Microstructure yam ntxwv
Ntev- chains polymer qauv: Yas siv siab-molecular- hnyav polymers raws li matrix, muaj ntau cov kab rov ua dua tshiab txuas ua ke los tsim cov saw hlau ntev. Qhov nruab nrab molecular hnyav ntawm kev lag luam plastics feem ntau yog nruab nrab ntawm 10,000 thiab 500,000, nrog rau cov saw hlau molecular intertwined los ua ib qho kev sib koom ua ke.
Qhov sib txawv ntawm cov qauv: Feem ntau cov thermoplastics yog linear lossis branched macromolecules. Tsuas yog ib qho me me ntawm cov thermosetting plastics muaj peb - qhov sib txawv ntawm tus ntoo khaub lig- txuas cov qauv sib txuas. Qhov kev sib txuas ntawm tus ntoo khaub lig- kev sib txuas yog qis dua li ntawm cov roj hmab, thiab qhov kev taw qhia ntawm cov khoom siv kuj tseem qis dua li cov ntaub ntawv fiber ntau.
Intermolecular force yam ntxwv: Cov saw hlau molecular raug khi ua ke los ntawm lub zog tsis muaj zog xws li van der Waals rog thiab hydrogen bonds, es tsis yog covalent bonds. Qhov no ua rau cov saw hlau molecular ntawm cov yas yooj yim zawv zawg thaum rhuab, nthuav tawm cov yam ntxwv viscoelastic.
Macroscopic Moulding Tus yam ntxwv
Strong molding adaptability: Yas tuaj yeem ua tiav siv ntau tshaj peb caug txheej txheem, suav nrog kev txhaj tshuaj molding, extrusion, tshuab moulding, thiab lub tshuab nqus tsev tsim, los tsim ntau yam khoom siv xws li qhov nyuaj precision mus rau cov thawv loj loj.
Cov khoom sib txawv: Nws tuaj yeem tsim cov kav dej txuas ntxiv, cov ntaub ntawv thiab lwm yam kev sib tw ntev - ntu cov qauv, nrog rau cov qauv tsis sib xws nrog cov buckles zoo thiab grooves. Nws tuaj yeem npaj cov qauv sib xyaw ua ke nrog cov micropores sab hauv los ntawm cov txheej txheem foaming.
