Tus yam ntxwv ntawm cov khoom siv hluav taws xob hauv cov khoom siv polymer feem ntau yog hais txog kev ntsuas ntawm lub zog, elasticity, viscoelasticity, thiab anisotropy ntawm cov khoom siv polymeric …, plastics, lossis cov polymers nruj nyob ntawm lawv cov khoom siv kho tshuab.
Dab tsi yog cov txheej txheem ua cim rau cov polymers?
Cov txuj ci twg yog siv hauv Kev Tshawb Fawb Polymer?
- Desorption mass spectrometry (DMS)
- Dynamic headspace gas chromatography-mass spectrometry (DHGCMS)
- Gas chromatography-mass spectrometry (GCMS)
Dab tsi yog cov yam ntxwv ntawm polymers?
Qee yam ntawm cov khoom muaj txiaj ntsig ntawm ntau yam engineering polymers yog siab lub zog lossis kev hloov pauv rau qhov hnyav piv(lub teeb yuag tab sis sib piv tawv thiab muaj zog), toughness, resilience, tsis kam corrosion, tsis muaj conductivity (kub thiab hluav taws xob), xim, pob tshab, ua, thiab tus nqi qis.
Cov txheej txheem twg yog siv rau kev tshuaj xyuas ntawm polymer?
Absorption Spectroscopy:
Cov tswv yim tseem ceeb rau kev txiav txim siab ntawm cov tshuaj muaj pes tsawg leeg thiab molecular topology koom nrog kev nqus ntawm electro-magnetic radiation los ntawm polymers. Cov txuj ci tseem ceeb yog IR, Raman, thiab NMR spectroscopy thiab feem ntau ntawm cov chav kawm no yuav koom nrog cov kev tshuaj ntsuam xyuas loj.
Koj paub cov polymers li cas?
Techniques siv los txheeb xyuas cov polymer muaj xws li hauv qab no:
- kev xeem ua ntej.
- Elemental analysis (Lassaigne's Test)
- Solubility test.
- IR tsom xam (KBr disc)
- Nplaim Test / Melting Test.
- Kev txiav txim siab tshwj xeeb.
