I-styrene iyinhlanganisela yezinto eziphilayo.Kuyi-monomer ye-polystyrene.i-polystyrene ayiyona into engokwemvelo.I-polymer eyenziwe nge-styrene yaziwa ngokuthi i-polystyrene.Kuyinhlanganisela yokwenziwa.Kule nhlanganisela kunendandatho ye-benzene.Ngakho-ke, yaziwa nangokuthi inhlanganisela enamakha.Kulesi sihloko, sihlanganise wonke amaphuzu abalulekile nemiqondo mayelana ne-styrenes njengefomula ye-styrene, ukusetshenziswa kwayo, ukuhlanganiswa kwe-styrene, isakhiwo se-styrene, kanye nezakhiwo zayo.
Ifomula ye-Styrene
Ifomula ye-styrene yesakhiwo ithi C6H5CH=CH2.Ifomula yamakhemikhali ye-styrene yi-C8H8.Inombolo ebhalwe kusikripthi sika-C imele inani lama-athomu ekhabhoni futhi inombolo ebhalwe ku-H imele inani lama-athomu e-hydrogen.I-C6H5 imele indandatho ye-benzyl futhi i-CH=CH2 imele amaketanga e-carbon alkene amabili.Igama le-IUPAC le-styrene yi-Ethenylbenzene.Esakhiweni se-styrene, indandatho eyodwa ye-benzene ixhunywe eqenjini le-vinyl nge-covalent bonding.Amabhondi amane e-pi akhona esakhiweni se-styrene.Lawa mabhondi e-pi akhona ngokushintshana ku-styrene.Ngenxa yokuhlelwa okunjalo izenzakalo ze-resonance zenzeka esakhiweni se-styrene.Ngaphandle kwalezi zibopho ze-pi amabhondi ayisishiyagalombili we-sigma nawo akhona esakhiweni se-styrene.Lawa mabhondi e-sigma akhona ku-styrene akhiwa ama-orbitals agqagqene phezulu.Amabhondi ka-pi akhiwa ukugqagqana kwe-lateral kwama-orbitals angama-p.
Izakhiwo ze-Styrene
● I-styrene iwuketshezi olungenambala.
● Isisindo sengqamuzana se-styrene singu-104.15 g/mol.
● Ukuminyana kwe-styrene ngu-0.909 g/cm³ kuthempelesha evamile yegumbi.
● Iphunga le-styrene limnandi ngokwemvelo.
● Ukunyibilika kwe-styrene ngu-0.24 g/lt.
● I-styrene iyavutha ngokwemvelo.
Ukusetshenziswa kwe-Styrene
● I-Polymeric Solid ye-styrene isetshenziselwa izinjongo zokupakisha.
● I-styrene isetshenziswa ekwenzeni iziqukathi zokudla eziqinile.
● I-Polymeric styrene isetshenziswa ekwenzeni izisetshenziswa zezokwelapha nezisetshenziswa zamehlo.
● Izinto zikagesi, amathoyizi ezingane, izinto zasekhishini, izinto zasendlini, neminye imikhiqizo eminingi yenziwa ngosizo lwe-styrene.
● Igwebu le-polystyrene liyinto engasindi.Ngakho-ke, ingasetshenziswa emaphaketheni okuvikela ngezinjongo zezinsizakalo zokudla.
● I-Polystyrene isetshenziswa ekwenzeni izingxenye zokwakha njenge-insulation material nokunye.
● I-styrene isetshenziswa ekwenzeni imikhiqizo eyinhlanganisela, le mikhiqizo yaziwa ngokuthi izinhlanganisela ze-polymer eziqiniswe nge-fiber (FRP).Lezi zingxenye zisetshenziswa ekwenzeni izingxenye zemoto.
● Ifomu le-styrene polymeric lisetshenziswa ekwenzeni amapayipi namathangi angagqwali.
● I-styrene isetshenziswa ezindaweni zokugezela nasezimpahleni zemidlalo.
● Amafilimu e-polystyrene asetshenziswa ekwenzeni i-laminating, nasekunyatheliseni izinhlelo zokusebenza.
