Iipropati zeMichiza:
Styrene lulwelo kwiqondo lobushushu, engenambala, kunye nevumba elibukhali, styrene ukutsha, indawo ebilayo 145.2 degrees Celsius, iqondo lomkhenkce -30.6 degrees Celsius, ubunzima obuthile 0.906, styrene ayinyibiliki emanzini, ukuba ngama-25 degrees Celsius, styrene ukunyibilika kuphela 0.066%.I-styrene inokuxutywa ne-ether, i-methyl ferment, i-carbon disulfide, i-acetone, i-benzene, i-toluene kunye ne-tetra-ironic carbon nayiphi na imilinganiselo.I-Styrene sisinyibilikisi esilungileyo serabha yendalo, irabha yokwenziwa kunye nezinto ezininzi eziphilayo.I-styrene inetyhefu, ukuba umzimba womntu uphefumle umphunga omninzi we-styrene uya kubangela ityhefu.Uxinzelelo oluvumelekileyo lwe-styrene emoyeni ngu-0.1mg/L.Umphunga we-styrene kunye nomoya uya kwenza umxube oqhumayo.
Isicelo:
I-Styrene yi-monomer ebalulekileyo yerabha yokwenziwa, i-adhesives kunye neeplastiki.[3,4,5] Isetyenziselwa ukuhlanganiswa kwerabha ye-styrene butadiene kunye ne-polystyrene resin, i-polyester glass fiber ifakwe iiplastiki kunye neengubo.Isetyenziselwa ukulungisa i-polystyrene, i-ion exchange resin, kunye ne-polystyrene yogwebu.Ikwasetyenziselwa i-copolymerization kunye nezinye ii-monomers ukuvelisa iiplastiki zobunjineli ezahlukeneyo, ezifana ne-copolymerization ye-acrylonitrile kunye ne-butadiene ukuvelisa i-resin ye-ABS, esetyenziswa ngokubanzi kwizixhobo zasekhaya ezahlukeneyo kunye namashishini.I-Copolymerization ene-acrylonitrile, efunyenwe i-SAN yintlaka enokumelana nokothuka kunye nombala oqaqambileyo.I-SBS eveliswe yi-copolymerization kunye ne-butadiene yirubha ye-thermoplastic, esetyenziswa ngokubanzi njenge-polyvinyl chloride kunye ne-acrylic modifier.I-SBS kunye ne-SIS thermoplastic elastomers zenziwe nge-butadiene kunye ne-isoprene copolymerization, kwaye njenge-monomer edibeneyo, i-styrene isetyenziselwa ukuguqulwa kwe-PVC, i-polypropylene, kunye ne-polyester engaxutywanga.
I-Syrene isetyenziswa njenge-monomer enzima kwimveliso ye-styrene acrylic emulsion kunye ne-solvent pressure adhesive adhesive.I-Emulsion adhesive kunye nepeyinti ingalungiswa nge-copolymerization kunye ne-vinyl acetate kunye ne-acrylic ester.I-styrene yenye yezona zinto zixhaphakileyo zisetyenziswa kwi-vinyl monomers kwicandelo lezenzululwazi, esetyenziswa kwizinto ezahlukeneyo ezilungisiweyo nezihlanganisiweyo.
Ukongeza, inani elincinci le-styrene likwasetyenziswa njengeziqholo kunye nezinye iziphakathi.Nge-chloromethylation ye-styrene, i-cinnamyl chloride isetyenziswa njenge-intermediate ye-non-analgesic analgesic eqinile ukuzimisela ukuzimisela iintlungu, kwaye i-styrene ikwasetyenziswa njengeyeza elichasayo, i-expectorant kunye ne-anticholinergic yokuqala ekuTshintsheni kwesisu.Ingasetyenziselwa ukwenza i-anthraquinones yedayi ephakathi, i-emulsifiers ye-pesticide, kunye ne-styrene phosphonic acids i-ore yokunxiba i-agent kunye nezikhanyisi zobhedu.
