Thermoplastic pellets soften thaum rhuab thiab ua kua ntau dua li cov cua sov ntau dua. Cov txheej txheem kho yog 100% thim rov qab vim tsis muaj tshuaj lom neeg sib koom ua ke. Cov yam ntxwv no tso cai rau cov thermoplastics tuaj yeem rov ua dua thiab rov ua dua yam tsis muaj kev cuam tshuam rau cov khoom siv lub cev. Muaj ntau hom thermoplastic resins uas muaj ntau yam txiaj ntsig kev ua tau zoo, tab sis feem ntau ntawm cov khoom siv feem ntau muaj lub zog siab, ntsws-ua haujlwm, thiab yooj yim yooj yim. Raws li cov resin, cov khoom siv thermoplastics tuaj yeem ua rau cov ntawv thov kev ntxhov siab tsawg xws li cov hnab yas lossis tuaj yeem siv rau hauv cov khoom siv hluav taws xob siab. Piv txwv ntawm thermoplastic polymers muaj xws li polyethylene, PVC, thiab nylon. 1
Daim ntawv tshaj tawm ntawm Superplasticizers Kev Lag Luam muab tag nrho cov ntaub ntawv tshawb fawb txog cov ntsiab lus, kev loj hlob, kev thov thiab kev kwv yees kev txheeb xyuas qhia tag nrho thoob plaws ntiaj teb. Superplasticizers kev lag luam tau kwv yees kom loj hlob ntawm tus nqi maj mam thaum lub sijhawm kwv yees. Tsis tas li ntawd, tsab ntawv ceeb toom suav nrog luv luv ntawm kev tshawb fawb kev lag luam nrog rau cov hauv kev muaj los ntawm kev ua lag luam.

Cov qauv XRD ntawm N-doped graphene hauv daim duab 2(g) qhia qhov dav dav diffraction ncov ntawm li 25.9 ° uas sib haum rau (002) diffraction ntawm ob peb txheej graphene, thiab rau cov qauv 0 thiab 1, qhov diffraction ncov ntawm 42.7 ° yog tus yam ntxwv ntawm graphite ntawm (100) diffraction. Qhov tsis muaj zog peak siv hauv daim duab 2(g) qhia tias qhov nruab nrab txheej ntawm daim ntawv graphene tau txais tsawg dua qhov tau txais ua ntej siv txoj kev zoo sib xws48,52.
