Styrene waa walxo kiimiko ah oo dareere ah oo muhiim ah.Waa hydrocarbon caraf udgoon monocyclic leh silsilad dhinaca alkene ah oo la sameeyay nidaamka isku xidhka oo leh giraanta benzene.Waa xubinta ugu fudud uguna muhiimsan ee hydrocarbons caraf udgoon oo aan dhergin.Styrene waxaa si ballaaran loo isticmaalaa sida alaabta ceeriin ee soo saarista resins synthetic iyo caag.
Styrene waa walxo kiimiko ah oo dareere ah oo muhiim ah, oo ka tirsan hydrocarbon caraf udgoon monocyclic leh silsilad dhinaca alkene ah oo samaynaysa nidaam isku xidhan oo leh giraanta benzene.Waa styrene udgoon udgoon udgoon "sida dhuxusha saliidda iyo isku xirka caag iyo balaastig ah", waana alaabta aasaasiga ah ee organic aasaasiga ah ee warshadaha petrochemical.Dulmarka tooska ah ee styrene waa benzene iyo ethylene, iyo qulqulka hoose waa mid kala firirsan.Alaabooyinka ugu muhiimsan ee ku lug leh waa polystyrene xumbo, polystyrene, resin ABS, caag synthetic, resin polyester aan saturated iyo copolymers styrene, iyo terminal inta badan waxaa loo isticmaalaa caag ah iyo alaabta caag synthetic.
2010 balaadhinta awoodda wax soo saarka styrene adduunka, si xoog leh markii kororka ku saabsan 2.78 milyan oo tan oo awoodda wax soo saarka, kobaca wax soo saarka ayaa ku dhow 10%, inta badan waa adduunka gaar ahaan Shiinaha si ay wax soo saarka hoose ee styrene (terminal loo isticmaalo qalabka guriga, baabuurta iyo warshadaha qalabka dhismaha) isticmaalka, kaas oo 2009 iyo 2010, baahida Shiinaha ee Styrene ayaa ka sarreeyay 15%.Ka dib 2010, heerka kobaca awoodda wax-soo-saarka styrene-ga caalamiga ah ayaa si tartiib tartiib ah hoos ugu dhacay, iyo dhammaadka 2017, awoodda wax-soo-saarka styrene ee caalamiga ah waxay gaartay 33.724 milyan tan.
Awoodda wax-soo-saarka styrene ee dunidu waxay inta badan ku urursan tahay Bariga Aasiya, Waqooyiga Ameerika iyo Galbeedka Yurub, kuwaas oo 78.9% ka ah awoodda wax-soo-saarka styrene ee adduunka.Intaa waxaa dheer, gobolka Aasiya-Pacific wuxuu xisaabiyaa boqolkiiba 52 awoodda wax-soo-saarka styrene ee adduunka.
Baahida dhanka hoose ee styrene waa mid aad u kala firdhisan, alaabada ugu danbeysana waxay u badan tahay baco iyo caag synthetic ah.
Laga soo bilaabo baahida caalamiga ah ee styrene ee 2016, 37.8% styrene ayaa lagu dabaqaa polystyrene, 22.1% si loo xumbo polystyrene, 15.9% ilaa ABS resin, 9.9% caag butadiene styrene, 4.8% resin unsaturated, iwm.
Kordhinta awoodda wax soo saarka gudaha ee cusub, mugga soo dejinta styrene ee Shiinaha iyo ku tiirsanaanta soo dejinta ayaa si tartiib tartiib ah hoos ugu dhacday sannadihii u dambeeyay.
Sida laga soo xigtay xogta kastamka, sanadka 2018, wadamada Shiinaha ee ugu badan ee ay soo dejiyaan Styrene waa Saudi Arabia, Japan, South Korea, Singapore, iwm. Kahor 2017, ilaha ugu weyn ee laga soo dejiyo Styrene waxay ahaayeen South Korea, Saudi Arabia iyo Maraykanka, iyadoo South Korea ay ahayd. isha ugu weyn ee laga keeno.
Tan iyo Juun 23, 2018, Wasaaradda Ganacsiga Shiinaha ayaa ku soo rogtay canshuuraha ka hortagga qashinka oo u dhexeeya 3.8% ilaa 55.7% styrene laga keeno Jamhuuriyadda Kuuriya iyo Maraykanka muddo shan sano ah, taasoo keentay hoos u dhac weyn saamiga Shiinaha ee laga keeno Jamhuuriyadda Kuuriya qeybtii labaad ee 2018, iyadoo Sacuudi Carabiya iyo Japan ay noqdeen kuwa ugu badan ee laga keeno.
Iyada oo wax soo saarka degdega ah ee sifaynta gaarka loo leeyahay ee gudaha, tiro badan oo ah awoodda wax soo saarka cusub ee styrene ayaa la gelin doonaa shaqada Shiinaha mustaqbalka.
Muddadii "Qorshaha Shanta Sano ee 13aad", Shiinuhu wuxuu si habsami leh u dallacsiiyay mashaariicda sifaynta gaarka ah iyo isku-dhafka batroolka.Waqtigan xaadirka ah, Hengli, Sheng iyo toban milyan oo kale oo sifeyn heer ah iyo mashaariicda is dhexgalka batroolka ayaa la oggolaaday inay galaan xilliga ugu sarreeya ee dhismaha, iyo badi shirkadaha sifaynta iyo batroolka ee waaweyn waxay taageeraan aaladaha styrene-ka hoose.
