SBS (styrene –butadiene block copolymer)
NA WAIWAI A ME NA PONO
ʻO Styrene-butadiene block copolymers kahi papa koʻikoʻi o nā lāʻau synthetic.ʻO nā ʻano mea maʻamau ʻelua he linear a me radial triblock copolymers i loaʻa nā poloka waena a me nā poloka hope polystyrene.Hoʻohui nā elastomers SBS i nā waiwai o kahi resins thermoplastic me nā waiwai o ka rubber butadiene.ʻO nā poloka styrene paʻakikī, hāʻawi i ka ikaika mechanical a hoʻomaikaʻi i ka pale ʻana i ka abrasion, ʻoiai ʻo ka pahu waena waena e hāʻawi i ka maʻalahi a me ka paʻakikī.
Ma nā manaʻo he nui, loaʻa i nā elastomers SBS me kahi maʻiʻo haʻahaʻa styrene i nā waiwai like me ka vulcanized butadiene rubber akā hiki ke hoʻoheheʻe ʻia a hoʻopau ʻia me ka hoʻohana ʻana i nā lako hana thermoplastic maʻamau.Eia naʻe, ʻoi aku ka liʻiliʻi o ka SBS ma mua o ke kinikini crosslinked (vulcanized) butadiene rubber a no laila, ʻaʻole e hoʻōla maikaʻi mai ka deformation e like me ka vulcanized diene elastomers.
Hoʻohui pinepine ʻia nā ʻōpala SBS me nā polymers ʻē aʻe e hoʻomaikaʻi i kā lākou hana.Hoʻohui pinepine ʻia ka ʻaila a me nā mea hoʻopiha i ke kumukūʻai haʻahaʻa a e hoʻololi hou i kā lākou mau waiwai.

Hoʻohana ʻia ʻo SBS i nā ʻoihana like ʻole:kaʻa, hoʻololi bitumen, HIPS, kapu kāmaʻa a me masterbatch.ʻOi aku ka maikaʻi o ka lāʻau synthetic ma mua o ka lāʻau maoli no ka mea ʻoi aku ka maʻemaʻe a maʻalahi hoʻi ka mālama ʻana.ʻO kekahi o nā huahana koʻikoʻi o BassTech, ʻo styrene-butadiene styrene (SBS), he lāʻau synthetic maʻamau i hoʻohana ʻia i ka hana ʻoihana.
1. Hoʻopili ʻia ʻo Styrene-butadiene styrene ma ke ʻano he elastomer thermoplastic.
Ma ke ʻano he elastomer thermoplastic, maʻalahi ka hana ʻana a me ka hana hou ʻana iā SBS i ka wā i wela ai.Ma ka hoʻomehana ʻana, hana ia e like me ka plastic a hiki ke hana.ʻO kona hoʻolālā (block copolymer me nā kaulahao polystyrene ʻelua) e hiki ai ke hui pū ʻia me ka paʻakikī paʻakikī a me nā waiwai elastic.
2. Ke hoʻohālikelike ʻia me ka vulcanized rubber maʻamau, me ka hoʻohana ʻana i ka styrene-butadiene styrene hiki ke kōkua i ka hōʻemi ʻana i nā kumukūʻai hana.
Hiki ke hana hou ia, pale i ka abrasion a ʻaʻole pono i ka vulcanizing.He mau makahiki maikaʻi ʻo SBS a ʻaʻole hiki ke ʻaʻahu maʻalahi, e hōʻemi ana i ka pono no ka hoʻoponopono ʻana a hoʻolilo iā ia i mea waiwai nui o nā huahana hale.
3. He kūpono loa ka Styrene-butadiene styrene no nā noi hale.
Hoʻohana nui ʻia ʻo SBS i nā noi hale e like me ka hoʻololi ʻana i ka bitumen, nā mea sila wai a me nā uhi wai.I nā mahana anu, paʻa mau ka SBS, ʻoluʻolu a kūpaʻa i ka makū.Ma waho aʻe o ka uhi ʻana, hoʻohana ʻia ʻo SBS i ka paving, sealants a me nā uhi e hoʻohui i ka maʻalahi anuanu a hōʻemi i ka hoʻolaha ʻana o ka pohā luku.Ma ke ʻano he hoʻololi asphalt, pale ʻo SBS i nā lua a me nā māwae maʻamau i hana ʻia e ka haʻalulu wela.
4. He mea kaulana ka Styrene-butadiene styrene no nā mea hana kāma'a.
He mea maikaʻi loa ʻo SBS i ka hana ʻana i nā kāmaʻa no nā kumu like ʻole e kūpono ai no ka uhi ʻana.Ma nā kapua'i kāma'a, hā'awi ka styrene-butadiene styrene i kahi huahana ikaika akā hiki ke ho'opa'a 'ia i ka wai.
