Faahfaahin:

Guryaha Kiimikada:

Styrene waa unug kiimiko oo dabiici ah oo gaar ah oo leh qaacidada kiimikada C8H8 iyo qaacidada qaabdhismeedka CH2=CHC6H5, sidoo kale loo yaqaan styrol, vinylbenzene, phenylethene, phenylethylene, styrene, styreen iyo wixii la mid ah.Qaab dhismeedkeeda kiimikaad waxa uu ka samaysan yahay giraan benzene ah oo ku xidhan koox vinyl ah .Heerkulka qolka iyo cadaadiska, styrene waa dareere cad oo aan midab lahayn.Styrene waa monomer muhiim ah oo ka samaysan caag synthetic, xabagta iyo balaastikada, sida xaashida styrene.

Codsiga:

Styrene waa monomer muhiim ah oo ka samaysan caag synthetic, xabagta iyo balaastikada.[3,4,5] Waxaa loo isticmaalaa isku-dhafka styrene butadiene caagga ah iyo resin polystyrene, fiber galaas polyester xoojiyay balaastiigyada iyo dahaarka.Waxaa loo isticmaalaa diyaarinta polystyrene, xabagta sarrifka ion, iyo polystyrene xumbo.Waxa kale oo loo istcimaalay isku-duubnida monomers kale si loo soo saaro balaastikada kala duwan ee injineernimada, sida copolymerization of acrylonitrile iyo butadiene si loo soo saaro resin ABS, oo si weyn loogu isticmaalo qalabyada kala duwan ee guryaha iyo warshadaha.Copolymerization with acrylonitrile, helay SAN waa resin leh iska caabin naxdin leh iyo midab dhalaalaya.SBS-da ay soo saartay copolymerization with butadiene waa caag heerkulbeeg ah, kaas oo si weyn loogu isticmaalo sidii chloride polyvinyl iyo acrylic modifier.SBS iyo SIS thermoplastic elastomers waxaa lagu sameeyay butadiene iyo isoprene copolymerization, iyo monomer-ka isdhaafsan, styrene waxaa loo isticmaalaa wax ka beddelka PVC, polypropylene, iyo polyester aan saturated ahayn.
Syrene waxaa loo isticmaalaa sidii monomer adag soo saarista emulsion styrene acrylic iyo xabagta xasaasiga ah ee cadaadiska dareeraha.Xabagta Emulsion iyo rinjiga waxaa lagu diyaarin karaa koobiyeerka oo leh vinyl acetate iyo acrylic ester.Styrene waa mid ka mid ah monomers-ka vinyl-ka inta badan loo isticmaalo goobta sayniska, oo loo isticmaalo agabyo kala duwan oo wax laga beddelay iyo kuwo isku dhafan.[6]
Intaa waxaa dheer, qadar yar oo styrene ah ayaa sidoo kale loo isticmaalaa sida cadar iyo dhexdhexaadin kale.Marka loo eego chloromethylation of styrene, chloride cinnamyl waxaa loo isticmaalaa dhexdhexaad si loo go'aamiyo xanuunka suuxdinta aan suuxdinta lahayn, iyo styrene sidoo kale waxaa loo isticmaalaa daawada asalka ah ee antitussive, expectorant iyo anticholinergic ee isbedelka caloosha.Waxaa loo isticmaali karaa in lagu sameeyo dhexdhexaadiyeyaasha dheeha anthraquinones, emulsifiers-ka sunta cayayaanka, iyo styrene fosphonic acids ore dhaymada iyo dhalaaliyeyaasha naxaasta ah.
