SIS(Styrene-isoprene-styrene block copolymer)
ʻO Baling Petrochemical SIS he styrene - isoprene block copolymer i ke ʻano o ke keʻokeʻo porous particle a i ʻole translucent compact particle, me nā hiʻohiʻona o ka thermo-plasticity maikaʻi, elasticity kiʻekiʻe, ka wai hoʻoheheʻe maikaʻi, kūpono maikaʻi me ka tackifying resin, palekana a ʻaʻole ʻona.Hiki ke hoʻopili ʻia i nā mea hoʻoheheʻe wela wela, nā mea hoʻoheheʻe ʻana, nā papa paʻi maʻalahi, nā plastics a me ka hoʻololi ʻana i ka asphalt, a ʻo ia nā mea waiwai kūpono o nā mea hoʻopili i hoʻohana ʻia no ka hana ʻana i nā ʻeke paʻi, nā lako hoʻomaʻemaʻe, nā ʻāpana ʻaoʻao ʻelua a me nā lepili. .
NA WAIWAI A ME NA PONO
ʻO Styrene-isoprene block copolymers (SIS) he leo nui, haʻahaʻa kumu kūʻai thermoplastic elastomers (TPE) i hana ʻia e ke ola ionic copolymerization ma o ka hoʻokomo ʻana i ka styrene, 2-methyl-1,3-butadiene (isoprene), a me ka styrene i loko o ka reactor. .ʻOkoʻa ka maʻiʻo styrene ma waena o 15 a 40 pakeneka.Ke hoʻoluʻu ʻia ma lalo o ka helu hoʻoheheʻe, ʻo SIS me kahi haʻahaʻa styrene maʻiʻo haʻahaʻa-e hoʻokaʻawale ʻia i loko o nā ʻāpana polystyrene nano-nui i hoʻokomo ʻia i loko o kahi matrix isoprene aʻo ka piʻi ʻana o ka maʻiʻo styrene e alakaʻi i ka cylindrical a laila i nā hale lamellar.Hoʻohana nā kāʻei styrene paʻakikī e like me nā crosslinks kino e hāʻawi ai i ka ikaika mechanical a hoʻomaikaʻi i ke kūpaʻa abrasion, aʻo ka isoprene rubber matrix e hāʻawi i ka maʻalahi a me ka paʻakikī.ʻO nā mea mechanical o nā elastomers SIS me kahi haʻahaʻa haʻahaʻa styrene e like me nā mea o nā rubbers vulcanized.Eia nō naʻe, ʻaʻole like me ka vulcanized rubber, hiki ke hana ʻia nā elastomers SIS me nā mea hana i hoʻohana ʻia no ka hana ʻana i nā polymers thermoplastic.
Hoʻohui pinepine ʻia nā copolymers block SIS me nā resins tackifier, nā aila a me nā mea hoʻopihapiha, e hiki ai ke hoʻololi i nā waiwai huahana a i ʻole e hoʻohui ʻia i nā polymers thermoplastic e hoʻomaikaʻi i kā lākou hana.
Hoʻohana nui ʻia nā copolymers SIS i nā mea hoʻopili wela, nā mea hoʻopaʻa, nā mea hoʻoheheʻe gasket, nā kaula hao, nā mea pāʻani, nā kāmaʻa a me nā huahana bitumen no ka paving alanui a me nā noi hale.Hoʻohana ʻia lākou e like me ka hoʻololi ʻana i ka hopena a me nā mea paʻakikī i nā plastics a me (structural) adhesives.
