Isicelo somkhiqizo
Isetshenziselwa ukwenza ama-rubber, amapulasitiki, nama-polymers.
a) Ukukhiqizwa kwe: i-polystyrene enwebekayo (EPS);
b) Ukukhiqizwa kwe-polystyrene (HIPS) kanye ne-GPPS;
c) Ukukhiqizwa kwama-styrenic co-polymers;
d) Ukukhiqizwa kwezinsalela ze-polyester ezingagcwele;
e) Ukukhiqizwa kwerabha ye-styrene-butadiene;
f) Ukukhiqizwa kwe-styrene-butadiene latex;
g) Ukukhiqizwa kwama-styrene isoprene co-polymers;
h) Ukukhiqizwa kwe-styrene based polymeric dispersions;
i) Ukukhiqizwa kwama-polyols agcwele.I-styrene isetshenziswa kakhulu njenge-monomer ekwenzeni ama-polymers (njenge-polystyrene, noma irabha ethile ne-latex)
I-Styrene maleic anhydride (i-SMA noma i-SMAnh) i-polymer yokwenziwa eyakhiwe nge-styrene kanye ne-maleic anhydride monomers.Ama-monomers angacishe ashintshane kahle, ayenze i-copolymer eshintshanayo, [1] kodwa (okungahleliwe) i-copolymerization enokuqukethwe okungaphansi kuka-50% kwe-anhydride yesilisa nakho kungenzeka.I-polymer yenziwa nge-radical polymerization, isebenzisa i-organic peroxide njengesiqalo.Izici eziyinhloko ze-SMA copolymer ukubukeka kwayo okusobala, ukumelana nokushisa okuphezulu, ukuzinza okuphezulu kwe-dimensional, kanye nokusebenza kabusha okuqondile kwamaqembu e-anhydride.Isici sakamuva siphumela ekuncibilikeni kwe-SMA kuzixazululo ze-alkaline (esekelwe emanzini) kanye nokuhlakazeka.
I-SMA itholakala kuhlu olubanzi lwezisindo zamangqamuzana nokuqukethwe kwe-maleic anhydride (MA).Ekuhlanganisweni okujwayelekile kwalezo zakhiwo ezimbili, i-SMA iyatholakala njengegranule ecwebezelayo engasetshenziswa kuzinhlelo zokusebenza ezihlukahlukene.Ama-polymer e-SMA anesisindo samangqamuzana aphezulu asetshenziswa kakhulu ezinhlelweni zepulasitiki zobunjiniyela, ngokuvamile emthelela oguquliwe kanye nokwahlukahlukana okugcwele kwengilazi okungakhethwa kukho.Kungenjalo, i-SMA isetshenziswa kusetshenziswa ukukhanya kwayo kuhlanganiswe nezinye izinto ezibonisa ngale njenge-PMMA noma ukumelana nokushisa kokukhulisa ukushisa kwezinye izinto zama-polymers njenge-ABS noma i-PVC.I-solubility ye-SMA kuzixazululo ze-alkaline iyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene emkhakheni wokulinganisa (iphepha), ama-binders, ama-dipersants kanye nama-coatings.Ukuphinda kusebenze okuthile kwe-SMA kuyenza ibe i-ejenti efanelekile yokusebenzisana nama-polymer ngokuvamile angasebenzisani (isb. ama-ABS/PA ama-blends) noma ama-cross-link.Izinga lokushisa lokushintsha kwengilazi le-Styrene maleic anhydride lingu-130 - 160 °C.
