Chemical Properties:
Styrene imvura iri pakamuri tembiricha, isina ruvara, ine kunhuhwirira kwakashata, styrene inopfuta, inofashaira poindi 145.2 madhigirii celsius, nechando nzvimbo -30.6 madhigirii Celsius, chaiyo giravhiti 0.906, styrene hainyunguriki mumvura, kana iri 25 madhigirii Celsius, styrene. solubility inongova 0.066%. Styrene inogona kusanganiswa ne ether, methyl ferment, carbon disulfide, acetone, benzene, toluene uye tetra-ironic carbon mune chero chikamu. Styrene inonyungudutsa yakanaka yerabha rabha, synthetic rabha uye akawanda organic komisheni. Styrene ine chepfu, kana muviri wemunhu ukafemerwa yakawandisa styrene vapor inokonzera chepfu. Iyo inotenderwa kusungirirwa kwe styrene mumhepo ndeye 0.1mg/L. Styrene mhute nemhepo zvinogadzira musanganiswa unoputika.
Application:
Styrene yakakosha monomer ye synthetic rubber, adhesives uye mapurasitiki. [3,4,5] Inoshandiswa pakugadzirwa kwe styrene butadiene rubber uye polystyrene resin, polyester glass fiber yakasimbiswa mapurasitiki uye machira. Inoshandiswa kugadzira polystyrene, ion exchange resin, uye foam polystyrene. Inoshandiswawo kucopolymerization nemamwe mamonmers kugadzira akasiyana einjiniya mapurasitiki, akadai secopolymerization yeacrylonitrile uye butadiene kugadzira ABS resin, inoshandiswa zvakanyanya mumidziyo yakasiyana yemumba nemaindasitiri. Copolymerization ine acrylonitrile, yakawanikwa SAN iresin ine kuvhunduka uye ruvara rwakajeka. Iyo SBS inogadzirwa necopolymerization ine butadiene ndeye thermoplastic rabha, iyo inoshandiswa zvakanyanya se polyvinyl chloride uye acrylic modifier. SBS neSIS thermoplastic elastomers inogadzirwa nebutadiene uye isoprene copolymerization, uye semuchinjika monomer, styrene inoshandiswa mukugadziriswa kwePVC, polypropylene, uye unsaturated polyester.
Syrene inoshandiswa semonomer yakaoma pakugadzira styrene acrylic emulsion uye solvent pressure sensitive adhesive. Emulsion adhesive uye pendi inogona kugadzirwa necopolymerization nevinyl acetate uye acrylic ester. Styrene ndeimwe yeanonyanya kushandiswa mavinyl monomers mundima yesainzi, anoshandiswa mumhando dzakasiyana-siyana dzakagadziridzwa uye dzakaumbwa zvinhu.[6]
Mukuwedzera, chiduku chiduku che styrene chinoshandiswawo sezvinonhuwira uye zvimwe zvepakati. Ne chloromethylation ye styrene, cinnamyl chloride inoshandiswa sepakati kune iyo isiri anesthetic analgesic yakasimba marwadzo kutsunga, uye styrene inoshandiswawo se antitussive, expectorant uye anticholinergic yepakutanga mushonga mudumbu Kuchinja. Inogona kushandiswa kugadzira dhayi yepakati anthraquinones, emulsifiers yepesticide, uye styrene phosphonic acids ore dressing agent uye copper plating inopenya.
