Tshuaj lom neeg thiab uas soj ntsuam cov khoom ntawm Polystyrene

Pob tshab PS pellet uas yog tau ua los ntawm kev sib ntxiv polymerization txog styrene monomer, amorphous polymers. Tsis muaj kob, pob tshab, yav tom ntej kho qhov muag khoom thiab muaj rigidity. Nkig tawg, tom qab biaxial tensile dua mos thiab saj zawg zog, pob tshab sawv cev ntawm tus PS muaj raws li nram no:

Ceev 1.05 g/cm3

Tensile zog 48.3MPa.

Dabtsi yog khoov zog ntawm 82.7MPa.

Raug shrinkage 0.0045 rau/rau

5-8 x 10-5 hauv/coefficient ntawm thermal expansion (hauv • ° c)

Elongation feem pua

Vicat softening taw tes 225 f

Y-txoj sab ci kuj polystyrene xwb, thiaj li y-irradiation kom tsis muaj menyuam muaj tsis muaj feem rau kev kawm yam khoom. Polystyrene yog soluble hauv kuab tshuaj uas muaj ntxhiab thiab lwm yam ketones thiab methyl ethyl ketone neej nyob rau hauv. Pob tshab PS hais yaj Performance index ntau yog 1-25 g/10 min lossis siab dua ntawd tshaj 25 g/10 min. Nws muaj ib tug kub-resisting siab qib (Vicat softening taw tes 223 ° f), kuj muaj tsawg residual monomer qib kawm ntawd.
