styrene inoshandiswa mu polymers

Styrene ivhu rakajeka organic liquid hydrocarbon iyo inogadzirwa zvakanyanya kubva kune petroleum zvigadzirwa mushure mekuita kwechikamu chidiki distillation kubvisa olefins uye aromatics anodiwa kuti makemikari zvinhu kugadzira Styrene.Mazhinji petrochemical makemikari zvinomera zvakafanana nemufananidzo uri kurudyi.Tarira mbiru huru yakatwasuka inodaidzwa kuti fractional distillation column.Apa ndipo panodziiswa zvikamu zvepetroleum kusvika pakupisa kwepamusoro nekuti chimwe nechimwe chemakemikari makuru chine mapoinzi akasiyana siyana zvichizviparadzanisa nemazvo.

Styrene ndiyo inozivikanwa mumakemikari madenderedzwa semonomeri.Kuita kwemamonomers kugadzira "cheni" uye kugona kubatanidza pamwe nemamwe mamorekuru kwakakosha mukugadzirwa kwePolystyrene.Mamorekuru eStyrene anewo boka revinyl (ethenyl) rinogovana maerekitironi mukuita kunozivikanwa se covalent bonding, izvi zvinobvumira kuti igadzirwe kuita mapurasitiki.Kazhinji, Styrene inogadzirwa mumatanho maviri maitiro.Kutanga, iyo alkylation yebenzene (an unsaturated hydrocarbon) ine ethylene kugadzira ethylbenzene.Aluminium chloride catalyzed alkylation ichiri kushandiswa muzvirimwa zvakawanda zveEB (ethylbenzene) pasi rose.Kana izvozvo zvangoitwa, EB inoiswa kuburikidza nechaiyo chaiyo dehydrogenation process nekupfuura EB uye mupfunga pamusoro pekatalyst se iron oxide, aluminium chloride, kana nguva pfupi yadarika, yakagadziriswa-bed zeolite catalyst system kuti iwane yakachena kwazvo fomu yeStyrene.Inenge yese ethylbenzene inogadzirwa pasirese inoshandiswa kugadzira styrene.Kufambira mberi kwazvino mukugadzirwa kweStyrene kwakawedzera nzira dzinogona kugadzirwa naStyrene.Imwe nzira inonyanya kushandisa Toluene neMethanol pachinzvimbo cheEB.Kukwanisa kushandisa ma feedstocks akasiyana kunoita kuti Styrene ive sosi inodhura.

Petroleum Refining - Pfupi uye Inotapira

• Mafuta asina kuchena anopiswa uye anoshandurwa kuita mhute.
• Iyo inopisa mhute inokwira kumusoro kwechikamu chechikamu.
• Koramu inopisa kuzasi uye inotonhorera yakananga kumusoro.
• Sezvo hupfu hwega hwega hwehydrocarbon huchikwira nekutonhorera kusvika pakuvira kwayo hunokombwa nekuita mvura.
• Zvikamu zvemvura (mapoka emahydrocarbon ane mapoinzi akafanana ekuvira) anovharirwa mumatireyi uye anobviswa pombi.

Styrene zvakare yakakosha monomer mune aya maPolymers:

• Polystyrene
• EPS (Inowedzera Polystyrene)
• SAN (Styrene Acrylonitrile Resins)
• SB Latex
• ABS (Acrylonitrile Butadiene Styrene Resins)
• SB Rubber (Styrene-butadiene kubvira 1940's)
• Thermoplastic Elastomers (thermoplastic rubbers)
• MBS (Methacrylate Butadiene Styrene Resins)
