ʻO ka wai Butadiene Styrene Rubber (LSBR)
He copolymer kaumaha molekala haʻahaʻa ʻo LSBR o ka butadiene a me ka styrene me ke kaumaha molekala o 2000-10000. Loaʻa iā ia ka insulation uila maikaʻi loa a me nā waiwai kino, a hoʻohana pinepine ʻia ma nā ʻano he nui e like me nā papa kaapuni, nā mea hoʻopili a me nā mea sila.
Ke hoʻohālikelike ʻia me ka polibutadiene wai (LPB), loaʻa i ka LSBR kahi mahana hoʻololi aniani kiʻekiʻe a me ke kūpaʻa wela a me ke komo ʻana. ʻO ka hoʻololi ʻana iā LPB me LSBR hiki ke hoʻomaikaʻi i ke kahe ʻana o ka pipili i ka wā o ka hana ʻana o nā papa keleawe.
Hoʻopaʻa ʻia i loko o 50kg/pahu, 170kg/pahu, ʻO ka manawa mālama he 1 makahiki.
Nā kuhikuhi palekana:
Pono e mālama ʻia ma kahi anuanu, maloʻo a me ka ea. ʻO ke kūlana maikaʻi loa ma waena o -20 ~ 38℃. ʻO ke ola o ka papa he 12 mau mahina, inā pau, e hoʻohana mau ʻia inā kū i ke kūlana ma o ka hoʻāʻo hou ʻana. I ka wā e lawe ai, pono e pale i ka ua a me ka lā. Mai hoʻohuihui me ka oxidizer ikaika.
