Styrene chinhu chakakosha mvura kemikari mbishi zvinhu.Iyo monocyclic inonhuhwirira hydrocarbon ine alkene parutivi cheni uye yakagadzira conjugate system ine benzene mhete.Ndiyo yakapfava uye yakakosha nhengo yeunsaturated aromatic hydrocarbons.Styrene inoshandiswa zvakanyanya seyakagadzirwa kugadzirwa kwesynthetic resin uye rabha.
Styrene yakakosha mvura kemikari yakabikwa, ndeye monocyclic inonhuhwirira hydrocarbon ine alkene parutivi cheni uye ichigadzira conjugated system ine benzene mhete.Iyo isina unsaturated inonhuhwirira hydrocarbon styrene "inotakura mafuta marasha uye inobatanidza rabha nepurasitiki", uye yakakosha yakakosha organic raw material ye petrochemical industry.Iyo yakananga kumusoro kwe styrene ndeye benzene uye ethylene, uye zasi kwerwizi kwakapararira.Zvigadzirwa zvikuru zvinosanganisirwa zvinopupuma polystyrene, polystyrene, ABS resin, synthetic rabha, unsaturated polyester resin uye styrene copolymers, uye terminal inonyanya kushandiswa mumapurasitiki uye ekugadzira rabha zvigadzirwa.
2010 world styrene kugadzirwa kwesimba kuwedzera, zvakanyanya kana kuwedzera kweanosvika 2.78 miriyoni matani ekugadzira, kukura kwechigadzirwa kuri pedyo ne10%, kunyanya inyika kunyanya muChina kune zvigadzirwa zvezasi zve styrene (terminal inoshandiswa mumidziyo yemumba, mota uye. maindasitiri ezvekuvaka) kushandiswa, izvo muna 2009 uye 2010, kudiwa kweChina kwe styrene kwaive pamusoro pe15%.Mushure megore ra2010, chiyero chekukura kwepasi rose styrene kugadzirwa kwakadzikira zvishoma nezvishoma, uye pakupera kwa2017, yepasi rose styrene kugadzirwa kwakasvika 33.724 miriyoni matani.
Hunhu hwekugadzira styrene pasi rose hunonyanya kutariswa muEast Asia, North America neWestern Europe, iyo inoverengera 78.9% yepasi rose styrene kugadzira.Pamusoro pezvo, dunhu reAsia-Pacific rinotora 52 muzana yehuwandu hwekugadzira styrene pasi rose.
Iko kudiwa kwakadzika kwe styrene kwakapararira, uye zvigadzirwa zvekupedzisira zvinonyanya zvigadzirwa zvepurasitiki uye rekugadzira rabha.
Kubva pasi rose kudiwa kwestyrene muna 2016, 37.8% styrene inoshandiswa ku polystyrene, 22.1% kune polystyrene inopupuma, 15.9% kuABS resin, 9.9% kusvika styrene butadiene rabha, 4.8% kune unsaturated resin, nezvimwewo.
Nekuwedzera kwehutsva hutsva hwekugadzira mudzimba, huwandu hweChina hwekuunza styrene uye kutsamira kunze kwenyika kwakadzikira zvishoma mumakore apfuura.
Zvinoenderana nedata retsika, muna 2018, nyika dzeChina dzakanyanya kupinza styrene iSaudi Arabia, Japan, South Korea, Singapore, nezvimwewo. Gore ra2017 risati rasvika, masosi makuru ekutenga kunze kwenyika aive South Korea, Saudi Arabia neUnited States, neSouth Korea. iyo huru yekuunza kunze kwenyika.
Kubva munaChikumi 23, 2018, Ministry of Commerce of China yakatemesa mabasa ekurwisa kurasa marara kubva pa3.8% kusvika 55.7% pastyrene inotorwa kunze kwenyika kubva kuRepublic of Korea neUnited States kwenguva yemakore mashanu, zvichikonzera kudzikira kwakanyanya chikamu chezvinotengeswa neChina kubva kuRepublic of Korea muhafu yechipiri ya2018, neSaudi Arabia neJapan dzichiva nyika huru dzekutenga kunze kwenyika.
Nekugadzirwa kwakasimba kwezvigadziriso zvepachivande zvepamusha, huwandu hukuru hwehunyanzvi hwekugadzira styrene huchaiswa mukushanda muChina mune ramangwana.
Munguva ye "13th Five-Year Plan" nguva, China yakarongeka yakasimudzira kucheneswa kwepachivande uye mapurojekiti ekubatanidza petrochemical.Parizvino, Hengli, Sheng uye mamwe mamirioni gumi ekunatsa uye petrochemical mapurojekiti ekubatanidza akatenderwa kuti apinde panguva yepamusoro yekuvaka, uye mazhinji makuru ekunatsa uye petrochemical mabhizinesi anotsigira yakadzika styrene zvishandiso.
