Tono Hua
Ka whakamahia ki te hanga rapa, kirihou, polymers.
a) Te hanga: polystyrene whakawhänui (EPS);
b) Hangaia te polystyrene (HIPS) me te GPPS;
c) Te whakaputanga o nga polymer styrenic;
d) Te hanga kapia polyester haunga;
e) Te hanga rapa styrene-butadiene;
f) Te hanga taherapa styrene-butadiene;
g) Te hanga o te styrene isoprene co-polymers;
h) Te whakaputanga marara polymeric i runga i te styrene;
i) Te hanga polyol kua whakakiia.Ka whakamahia te Styrene hei monomer mo te hanga polymers (pērā i te polystyrene, etahi rapa me te latex)
Ko Styrene maleic anhydride (SMA or SMAnh) he polymer waihanga i hangaia mai i te styrene me te maleic anhydride monomers.Ka taea e nga monomers te huri tata tonu, na te mea he copolymer tauutuutu,[1] engari ka taea hoki te whakahiato (tupurangi) he iti iho i te 50% te ihirangi anhydride maleic.Ka hangaia te polymer e te polymerization tuwhena, ma te whakamahi i te peroxide waro hei kaikokiri.Ko nga ahuatanga matua o te SMA copolymer ko tona ahua maramara, te kaha o te wera, te pumau o te rahi, me te tauhohenga motuhake o nga roopu anhydride.Ko te ahuatanga o muri ko te whakarewatanga o te SMA i roto i nga otinga kawakore (wai-wai) me te marara.
Kei te waatea te SMA i roto i te whānuitanga o nga taumahatanga ngota me nga ihirangi maleic anhydride (MA).I roto i te huinga angamaheni o aua taonga e rua, kei te waatea a SMA hei kirikiri maramara maramara ka taea te whakamahi i roto i nga momo tono maha.Ko nga polymers SMA he nui te taumaha ngota e whakamahia nuitia ana i roto i nga tono kirihou miihini, i te nuinga o te waa i roto i te paanga kua whakarerekehia me te whakakii i te muka karaihe whiriwhiri.Hei tauira, ka tonohia a SMA ma te whakamahi i tona maaramatanga me etahi atu mea maamaa penei i te PMMA, te parenga wera ranei ki te whakamahana i etahi atu rauemi polymers penei i te ABS, PVC ranei.Ko te whakarewatanga o te SMA i roto i nga wairewa kawakore e tika ana mo nga momo tono i roto i te waahanga o te rahi (pepa), te here, te whakamarara me te paninga.Ko te tauhohenga motuhake o te SMA ka waiho hei kaihoko pai mo te hototahi i nga waerau hotokore (hei tauira, te whakakotahitanga o te ABS/PA), te hono whakawhiti ranei.Ko te pāmahana whakawhiti karaihe o Styrene maleic anhydride he 130 – 160 °C.
