Ibikoresho bya Shimi:

Styrene ni isukari ku bushyuhe bwicyumba, idafite ibara, ifite impumuro mbi, styrene irashya, ikabira dogere selisiyusi 145.2, ubukonje bwa dogere selisiyusi 30,6, uburemere bwihariye 0.906, styrene ntishobora gushonga mumazi, niba kuri dogere selisiyusi 25, styrene gukemura ni 0.066% gusa. Styrene irashobora kuvangwa na ether, ferment methyl, carbone disulfide, acetone, benzene, toluene na karubone ya tetra-ironic muburyo ubwo aribwo bwose. Styrene nigisubizo cyiza kuri reberi karemano, reberi yubukorikori hamwe nibintu byinshi kama. Styrene ni uburozi kandi irashobora gutera uburozi mugihe umubiri wumuntu uhumeka imyuka myinshi ya styrene. Kwemererwa kwibanda kuri styrene mu kirere ni 0.1mg / L. Umwuka wa Styrene n'umwuka bizakora imvange iturika.

Gusaba:

Styrene ni monomer yingenzi ya reberi yubukorikori, ibifata hamwe na plastiki. [3,4,5] Ikoreshwa muguhuza styrene butadiene reberi na resin polystirene, polyester ikirahure fibre ikomeza plastike hamwe na coatings. Ikoreshwa mugutegura polystirene, ion yoguhindura resin, hamwe na polystirene ifuro. Ikoreshwa kandi muri copolymerisation hamwe nabandi ba monomers kugirango ikore plastike zitandukanye zubuhanga, nka copolymerisation ya acrylonitrile na butadiene kugirango ikore ABS resin, ikoreshwa cyane mubikoresho bitandukanye byo murugo no mu nganda. Gukoporora hamwe na acrylonitrile, wabonye SAN ni resin irwanya ihungabana kandi ifite ibara ryiza. SBS ikorwa na copolymerisation hamwe na butadiene ni reberi ya termoplastique, ikoreshwa cyane nka chloride ya polyvinyl na moderi ya acrylic. SBS na SIS thermoplastique elastomers ikorwa na butadiene na isoprene copolymerisation, kandi nka monomer ihuza, styrene ikoreshwa muguhindura PVC, polypropilene, na polyester idahagije.
Syrene ikoreshwa nka monomer ikomeye kugirango ikore styrene acrylic emulsion hamwe na solvent yumuvuduko ukabije. Emulsion yometseho irangi irashobora gutegurwa na copolymerisation hamwe na vinyl acetate na acrylic ester. Styrene ni imwe mu zikoreshwa cyane muri vinyl monomers mu bumenyi bwa siyansi, ikoreshwa mu bikoresho bitandukanye byahinduwe kandi bihujwe.
Mubyongeyeho, umubare muto wa styrene nawo ukoreshwa nka parufe nabandi bahuza. Hamwe na chloromethylation ya styrene, cinnamyl chloride ikoreshwa nkigihe cyo kuvura ububabare budasanzwe bwa anesthetic analgesique, kandi styrene nayo ikoreshwa nkumuti wumwimerere urwanya antisitique, uteganya na anticholinergique mu gifu Guhinduka. Irashobora gukoreshwa muguhuza anthraquinones irangi irangi, imiti yica udukoko twica udukoko, hamwe na styrene fosifonique acide yambikwa amabuye hamwe nicyuma cyerekana umuringa.
