Hoʻohana Huahana
Hoʻohana ʻia i ka hana ʻana i nā rubbers, plastics, a me nā polymers.
a) Ka hana 'ana o: expandable polystyrene (EPS);
b) Ka hana ʻana o ka polystyrene (HIPS) a me GPPS;
c) Ka hana ʻana o nā styrenic co-polymers;
d) Ka hana ʻana i nā resins polyester unsaturated;
e) Ka hana ʻana o ka styrene-butadiene rubber;
f) Ka hana ʻana o ka styrene-butadiene latex;
g) Ka hana ʻana o nā styrene isoprene co-polymers;
h) Ka hana ʻana i nā dispersion polymeric ma muli o ka styrene;
i) Hana ʻia nā polyols piha.Hoʻohana nui ʻia ʻo Styrene ma ke ʻano he monomer no ka hana ʻana i nā polymers (e like me ka polystyrene, a i ʻole kekahi ʻōpala a me ka latex)
ʻO Styrene maleic anhydride (SMA a i ʻole SMAnh) he polymer synthetic i kūkulu ʻia me nā monomers styrene a maleic anhydride.Hiki i nā monomers ke ʻaneʻane hoʻololi, e hoʻolilo iā ia i copolymer ʻokoʻa, [1] akā hiki ke hana ʻia ka copolymerization me ka liʻiliʻi o 50% maleic anhydride maʻiʻo.Hoʻokumu ʻia ka polymer e kahi polymerization radical, me ka hoʻohana ʻana i ka peroxide organik e like me ka mea hoʻomaka.ʻO nā hiʻohiʻona nui o ka SMA copolymer kona hiʻohiʻona akaka, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe kiʻekiʻe, a me ka reactivity kikoʻī o nā hui anhydride.ʻO ka hiʻohiʻona hope ka hopena i ka solubility o SMA i nā hopena alkaline (wai-wai) a me ka hoʻopuehu.
Loaʻa ka SMA ma kahi ākea o nā paona molekala a me nā mea maleic anhydride (MA).Ma kahi hui maʻamau o ia mau waiwai ʻelua, loaʻa ʻo SMA ma ke ʻano he granule aniani i hiki ke hoʻohana ʻia i nā ʻano noi like ʻole.Hoʻohana nui ʻia nā polymers SMA me ke kaumaha molekala kiʻekiʻe i nā noi plastik ʻenekinia, ma ke ʻano maʻamau i ka hopena i hoʻololi ʻia a me nā koho aniani i hoʻopiha ʻia.ʻO kahi ʻē aʻe, hoʻohana ʻia ʻo SMA me ka hoʻohana ʻana i kona ʻike i ka hui pū ʻana me nā mea aniani ʻē aʻe e like me PMMA a i ʻole ka pale wela i ka wela-hoʻonui i nā mea polymers e like me ABS a i ʻole PVC.ʻO ka solubility o SMA i nā hopena alkaline e kūpono ia no nā noi like ʻole ma ke kahua o nā sizings (pepa), binders, dispersants a me nā uhi.ʻO ka hoʻoulu ʻana o SMA e lilo ia i mea kūpono no ka hoʻopili ʻana i nā polymers like ʻole (e laʻa me ka hui ʻana o ABS/PA) a i ʻole ka hoʻopili ʻana.ʻO ka mahana hoʻololi aniani o Styrene maleic anhydride he 130 – 160 °C.
