Sifooyinka kiimikada:

Styrene waa dareere ah heerkulka qolka, midab la'aan, oo leh udgoon, styrene waa olol, karkaraya-qarashka ah ee -30.6 Darajada Celsius. Xoolaha waa kaliya 0.066%. Styrene waxaa lagu qasi karaa taxsida ether, kaarboon methy, acetone, benzene, toluene iyo tetra-kaarboon kasta. Styrene waa solvent wanaagsan oo loogu talagalay caagga dabiiciga ah, caagga jilicsan iyo xeryo badan oo dabiici ah. Styrene waa sun sun ah, haddii jidhka bini-aadamka ee neefsashada uu neefsado uumiga aad u badan uu u horseedi doono sunta. U fiirsashada styrene ee styrene hawada waa 0.1MG / L. Uumiga styrene iyo hawo ayaa abuuri doonta isku dar walxaha qarxa.

Codsi:

Styrene waa monomer muhiim u ah caagga isku-darka, adheals iyo balaastigga. [3,4,5] waxaa loo isticmaalaa isku-darka styrene bapin-ka 'styrene' iyo polystyrene resing iyo polystyrene, fiber galaas polyester ah oo la xoojiyay balaastigga iyo jaakadaha. Waxaa loo isticmaalaa diyaarinta Polystyrene, ion isweydaarsiga ion, iyo Foom Polystyrene. Waxaa sidoo kale loo isticmaalaa in lagu sameeyo monomymerizars-ka kale si ay u soo saaraan balaastigyo kala duwan oo injineernimo ah, sida acrylonitrile iyo Budadiene si ay u soo saaraan maqnaanshaha appan, oo si weyn loogu isticmaalo qalabka guryaha iyo warshadaha. CocolumyMerization with acrylonitrile, oo laga helay San waa resin oo leh iska caabbinta naxdinta leh iyo midab dhalaalaya. SBS-yada ay soo saartay CopolyMerization with Budadiene waa caag heerkul ah, kaas oo si weyn loogu isticmaalo sida polyvinyl chloride iyo acrylier acrylier. SBS iyo Themontelas-ka SEMERERMOPLOMLOMLOMLOMLENE waxaa lagu sameeyaa Budadiene iyo Isoprene Tolomer TolomerMenemization, iyo monomle cromrene, styrene waxaa loo isticmaalaa in lagu beddelo PVC, polypropylene, iyo polyester-ka aan la furin.
Syrene waxaa loo isticmaalaa sidii monomer adag oo loogu talagalay soo saarista emulsion emulsion stryliinion iyo dareeraha culeyska xasaasiga ah ee xasaasiga ah. Dhexgalka emulsion-ka iyo rinjiga waxaa lagu diyaarin karaa qalabka lagu dhejiyo copolumymization leh vinyl acetate iyo acrylic estaro. Styrene waa mid ka mid ah kuwa ugu caansan ee loo yaqaan 'vinyl monomers' ee ugu badan ee loo adeegsado ee garoonka sayniska, loo isticmaalo waxyaabo kala duwan oo wax laga beddelay oo isku-dhafan. [6]
Intaa waxaa sii dheer, qadar yar oo styrene ah ayaa sidoo kale loo isticmaalaa sidii cadarka iyo isdhaafsiga kale. Waxaa qoray chloromeflation of styrene, qornyl chloride-ka waxaa loo isticmaalaa mid dhexe oo ah go'aan qaadashada xanuunka xoogga ee adag ee xanuunka, iyo styrene waxaa sidoo kale loo isticmaalaa sidii ka hortaga la-hortaga, icecate-ka iyo dawooyinka lidka ku ah dawada caloosha. Waxaa loo isticmaali karaa in lagu isticmaalo antraquiness-ka dheeh xididka, sunta sunta cayayaanka, iyo styrene phosphonic acids acids iyo wakiilka labiska ee naxaasta ah.
