Imikhiqizo

i-styrene ye-SBS

Incazelo emfushane:

I-styrene ngokuyinhloko iyikhemikhali yokwenziwa.Yaziwa nangokuthi i-vinylbenzene, ethenylbenzene, cinnamene, noma i-phenylethylene.Iwuketshezi olungenambala oluhwamuka kalula futhi lube nephunga elimnandi.Ngokuvamile iqukethe amanye amakhemikhali ayinikeza iphunga elibukhali, elingemnandi.Iyancibilika kolunye uketshezi kodwa ayincibiliki kalula emanzini.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

i-styrene ye-SBS,
I-styrene ye-Styrene Butadiene Styrene,

I-styrene-butadiene-styrene (SBS) iwuhlobo lwe-thermoplastic elastomer ene-elastomer efanayo nerabha ekushiseni okujwayelekile, futhi ingancibilika ukuze igeleze ekushiseni okuphezulu njengamapulasitiki, okubizwa ngokuthi impahla yepulasitiki.Ngakho, itiyela eliguquliwe le-SBS libonakala ngokuthi alibonakali lapho lishiselwa noma libe ntekenteke lapho selipholile;yepulasitiki enkulu kanye nempahla yokumelana nokuguga.Futhi i-asphalt eguquliwe ye-SBS manje isisetshenziswa ngempumelelo futhi esetshenziswe kabanzi eguquliwe.Inani le-SBS elengezwe ku-asphalt livamise ukuba phakathi kuka-5% ~ 10%.I-SBS ivamise ukusetshenziselwa ukwenza ulwelwesi olungangeni manzi kuphela kodwa futhi nokuvala impahla nopende ongangeni manzi.
