styrene ikoreshwa muri polymers

Styrene ni hydrocarubone isukuye yumubiri ikorwa cyane cyane mubikomoka kuri peteroli nyuma yuburyo bwo gutandukanya ibice kugirango ikuremo olefine na aromatiya ikenewe kugirango ibikoresho bya shimi bibyare Styrene.Ibimera byinshi bya peteroli-shimi bisa nishusho iburyo.Reba inkingi nini ihagaritse yitwa inkingi ya distillation inkingi.Aha niho ibice bya peteroli bishyushya ubushyuhe bwinshi kuko buri kintu cyingenzi cyimiti gifite ingingo zitandukanye zitetse bityo zikabatandukanya neza.

Styrene nicyo kizwi muri chimie chimie nka monomer.Imyitwarire ya monomers ikora "iminyururu" hamwe nubushobozi bwo guhuza nizindi molekile ni ngombwa mugukora Polystirene.Molekile ya Styrene irimo kandi vinyl group (ethenyl) isangira electron mugisubizo kizwi nka covalent bonding, ibi bituma ikorerwa muri plastiki.Kenshi, Styrene ikorwa muburyo bubiri.Ubwa mbere, alkylation ya benzene (hydrocarubone idahagije) hamwe na Ethylene kugirango itange Ethylbenzene.Aluminium chloride catisale alkylation iracyakoreshwa mubihingwa byinshi bya EB (ethylbenzene) kwisi yose.Iyo ibyo bimaze gukorwa, EB ishyirwa mubikorwa bya dehydrogenation isobanutse neza binyuze muri EB hamwe na parike hejuru ya catalizator nka oxyde de fer, aluminium chloride, cyangwa vuba aha, sisitemu ya catalizike ya zeolite itunganijwe kugirango ibone uburyo bwiza bwa Styrene.Hafi ya Ethylbenzene ikorerwa kwisi yose ikoreshwa mugukora styrene.Iterambere rya vuba mu musaruro wa Styrene ryongereye uburyo Styrene ishobora kubyazwa umusaruro.Inzira imwe byumwihariko ikoresha Toluene na Methanol aho gukoresha EB.Kubasha gukoresha ibiryo bitandukanye bituma Styrene umutungo uhendutse kurushanwa.

Gutunganya peteroli - Bigufi kandi Biryoshye

• Amavuta ya peteroli arashyuha agahinduka umwuka.
• Umwuka ushyushye uzamuka inkingi igabanya.
• Inkingi irashyushye hepfo kandi ikonja yerekeza hejuru.
• Iyo buri mwuka wa hydrocarubone uzamuka ugakonja aho utetse uraterana kandi ugakora amazi.
• Uduce duto twamazi (amatsinda ya hydrocarbone ifite ingingo zisa) zifatirwa mumurongo kandi zirasunikwa

Styrene nayo ni monomer yingenzi muri izi Polymers:

• Polystirene
• EPS (Ikwirakwizwa rya Polystirene)
• SAN (Styrene Acrylonitrile Resins)
• SB Latex
• ABS (Acrylonitrile Butadiene Styrene Resins)
• SB Rubber (Styrene-butadiene kuva 1940)
• Thermoplastique Elastomers (reberi ya termoplastique)
• MBS (Methacrylate Butadiene Styrene Resins)
