I-styrene isetshenziselwa ini?
I-styrene iyikhemikhali yokwenziwa evumelana nezimo futhi isetshenziswa ekwenzeni izinto ezisetshenziswayo ukukhiqiza imikhiqizo ehlukahlukene emangalisayo ezimbonini eziningi.Okuqashelwa kakhulu ezintweni ezisekelwe ku-styrene yi-polystyrene, cishe cishe i-65 % yazo zonke izithayela ezisetshenziselwa ukukhiqiza lokhu.I-Polystyrene isetshenziswa kuhlu olukhulu lwemikhiqizo yansuku zonke futhi ingatholakala emaphaketheni, amathoyizi, izinto zokungcebeleka, izinto zikagesi zabathengi nezigqoko zokuzivikela, uma sibala ezimbalwa.
Ezinye izinto ezikhiqizwayo zifaka i-acrylonitrile-butadiene styrene (ABS) kanye ne-styrene-acrylonitrile (SAN) resins futhi yenza cishe u-16 % wokusetshenziswa kwe-styrene.I-ABS iyinhlaka ye-thermoplastic esetshenziswa embonini yezimoto neyogesi, kanti i-SAN iyipulasitiki ehlanganisiwe esetshenziswa ezinhlobonhlobo zezimpahla zabathengi, ukupakisha, nezinhlelo zokusebenza zezimoto.
I-styrene iphinde isetshenziswe ekwenzeni i-styrene-butadiene rubber (SBR) elastomers kanye ne-latexes, futhi yenza cishe u-6% wokusetshenziswa.I-SBR isetshenziswa kumathayi emoto, namabhande namapayipi emishini, nasezintweni zasendlini njengamathoyizi, izipontshi namathayili aphansi.
I-Unsaturated polyester resin (UPR), eyaziwa kangcono njenge-fibreglass, ingenye into esekelwe ku-styrene futhi lokhu kubala cishe u-6% wokusetshenziswa kwe-styrene.
Ngokomlando, ukukhula kokusetshenziswa kwe-styrene kube kuhle nakuba lokhu kukhula kwehlile ngenxa yokuwohloka komnotho emhlabeni jikelele.
