Product Application
Amagwiritsidwa ntchito popanga mphira, mapulasitiki, ndi ma polima.
a) Kupanga: polystyrene yowonjezera (EPS);
b) Kupanga polystyrene (HIPS) ndi GPPS;
c) Kupanga ma styrenic co-polymers;
d) Kupanga unsaturated polyester resins;
e) Kupanga rabala ya styrene-butadiene;
f) Kupanga kwa styrene-butadiene latex;
g) Kupanga ma styrene isoprene co-polymers;
h) Kupanga kwa styrene based polymeric dispersions;
i) Kupanga ma polyols odzazidwa.Styrene imagwiritsidwa ntchito makamaka ngati monomer popanga ma polima (monga polystyrene, kapena labala ndi latex)
Styrene maleic anhydride (SMA kapena SMAnh) ndi polima yopanga yomwe imapangidwa ndi styrene ndi maleic anhydride monomers.Ma monomers amatha kukhala osinthika bwino kwambiri, ndikupangitsa kuti ikhale copolymer yosinthika, [1] koma (mwachisawawa) copolymerization yokhala ndi zosakwana 50% zamaleic anhydride ndizothekanso.Polima amapangidwa ndi kwambiri polymerization, ntchito organic peroxide monga woyambitsa.Makhalidwe akuluakulu a SMA copolymer ndi mawonekedwe ake owonekera, kukana kutentha kwakukulu, kukhazikika kwapamwamba, ndi kusinthika kwapadera kwa magulu a anhydride.Chotsatirachi chimapangitsa kuti SMA isungunuke muzitsulo za alkaline (madzi) ndi kubalalitsidwa.
SMA imapezeka muzolemera zambiri zamamolekyulu ndi maleic anhydride (MA) zomwe zili mkati.Kuphatikiza kwazinthu ziwirizi, SMA imapezeka ngati granule yowoneka bwino yomwe ingagwiritsidwe ntchito m'njira zosiyanasiyana.Ma polima a SMA okhala ndi kulemera kwakukulu kwa mamolekyu amagwiritsidwa ntchito kwambiri muuinjiniya wa pulasitiki, nthawi zambiri pamachitidwe osinthidwa komanso osankhidwa mwamagalasi odzaza magalasi.Kapenanso, SMA imagwiritsidwa ntchito pogwiritsa ntchito kuwonekera kwake kuphatikiza ndi zinthu zina zowonekera monga PMMA kapena kukana kutentha kumawonjezera kutentha kwa zinthu zina za polima monga ABS kapena PVC.Kusungunuka kwa SMA mumayankho a alkaline kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosiyanasiyana pamasinthidwe (mapepala), zomangira, zotulutsa ndi zokutira.Kukhazikika kwapadera kwa SMA kumapangitsa kuti ikhale yothandiza kuti igwirizane ndi ma polima omwe sangagwirizane (mwachitsanzo ABS/PA blends) kapena kuwoloka.Kutentha kwa galasi la Styrene maleic anhydride ndi 130 - 160 ° C.
