Styrene ndi organic pawiri.Ndi monomer wa polystyrene.polystyrene sizinthu zachilengedwe.Polima wopangidwa kuchokera ku styrene amadziwika kuti polystyrene.Ndi mankhwala opangidwa.Pagululi pali mphete ya benzene.Choncho, amadziwikanso ngati mankhwala onunkhira.M'nkhaniyi, takambirana mfundo zonse zofunika ndi mfundo za styrenes monga styrene formula, ntchito zake, kaphatikizidwe wa styrene, styrene kapangidwe, ndi katundu wake.
Fomu ya Styrene
Mapangidwe a styrene ndi C6H5CH=CH2.The styrene chemical formula ndi C8H8.Nambala yolembedwa mu subscript ya C imayimira kuchuluka kwa ma atomu a carbon ndipo nambala yolembedwa mu subscript ya H imayimira ma atomu a haidrojeni.C6H5 imayimira mphete ya benzyl ndipo CH = CH2 imayimira maunyolo awiri a carbon alkene.Dzina la IUPAC la styrene ndi Ethenylbenzene.Pamapangidwe a styrene, mphete imodzi ya benzene imamangiriridwa ku gulu la vinyl ndi covalent bonding.Zomangira zinayi za pi zilipo mu kapangidwe ka styrene.Ma pi bond awa amapezeka mosinthana mu styrene.Chifukwa cha dongosolo lotere, zochitika za resonance zimachitika mu kapangidwe ka styrene.Kupatula izi ma pi bond asanu ndi atatu a sigma nawonso amapezeka pamapangidwe a styrene.Zomangira za sigma zomwe zilipo mu styrene zimapangidwa ndi ma orbitals ozungulira mutu.Ma pi bond amapangidwa ndi kuphatikizika kwapakati kwa p orbitals.
Zithunzi za Styrene
● Styrene ndi madzi opanda mtundu.
● Kulemera kwa molekyulu ya styrene ndi 104.15 g/mol.
● Kachulukidwe ka styrene ndi 0.909 g/cm³ pa kutentha kwanthawi zonse.
● Fungo la styrene ndi lokoma.
● Kusungunuka kwa styrene ndi 0.24 g/lt.
● Sitimayi ndi yoyaka mwachilengedwe.
Styrene ntchito
● Polymeric Solid mtundu wa styrene amagwiritsidwa ntchito poyikapo.
● Styrene amagwiritsidwa ntchito popanga zotengera zolimba za chakudya.
● Polymeric styrene amagwiritsidwa ntchito popanga zida zamankhwala ndi zida zowunikira.
● Zida zamagetsi, zoseweretsa za ana, zida za m’khichini, za m’nyumba, ndi zinthu zina zambiri zimapangidwa ndi styrene.
● Foam polystyrene ndi chinthu chopepuka.Chifukwa chake, atha kugwiritsidwa ntchito m'mapaketi oteteza pazakudya.
● Polystyrene amagwiritsidwa ntchito popanga zinthu zomangira monga zotsekera ndi zina.
● Styrene amagwiritsidwa ntchito popanga zinthu za Composite, zomwe zimadziwika kuti fiber-reinforced polymer composites (FRP).Zidazi zimagwiritsidwa ntchito popanga zida zamagalimoto.
● Styrene polymeric form amagwiritsidwa ntchito popanga mapaipi ndi akasinja osachita dzimbiri.
● Styrene amagwiritsidwa ntchito m'bafa ndi m'zinthu zamasewera.
● Mafilimu a polystyrene amagwiritsidwa ntchito popangira laminating, ndi kusindikiza ntchito.
