ʻIke Laho III: Laho Styrene-Butadiene (SBR)
ʻO ka Styrene-Butadiene Rubber (SBR no ka pōkole) he laholio synthetic i hana ʻia e ka copolymerization o styrene a me butadiene. ʻO ia kekahi o nā laholio synthetic i hoʻohana nui ʻia ma ka honua holoʻokoʻa, e helu ana ma mua o 50% o ka hana ʻana o ka laholio synthetic. Aia kona mau waiwai ma waena o nā laholio kūlohelohe (NR) a me ka laholio butadiene (BR), a ua kaulana ia no kona kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, ke kumukūʻai haʻahaʻa, a me ke kūpaʻa kiʻekiʻe.
| Nʻano maoli | Fʻano | Hoʻohālikelike me ka laholio kūlohelohe (NR) |
| Ke kū'ē ʻana i ka abrasion | ʻOi aku ka maikaʻi ma mua o NR, kūpono no nā hiʻohiʻona friction kiʻekiʻe (e like me nā hehi o ka huila) | ʻAʻole maikaʻi loa ke kūpaʻa o ka NR i ke komo ʻana. |
| Ake kū'ē | ʻOi aku ka maikaʻi o ke kū'ē'ē antioxidant a me ka ozone ma mua o NR (ma muli o ke alo o nā apo benzene) | He maʻalahi ka NR i ka ʻelemakule a koi ʻia ka hoʻohui ʻana i nā mea anti-aging. |
| Ka Elasticity a me ka Hana Wela | ʻOi aku ka haʻahaʻa o ka elasticity ma mua o ka NR, a kiʻekiʻe loa ka hanauna wela hoʻololi (pono e hoʻomaikaʻi ʻia ke ʻano hana) | He elasticity maikaʻi loa ko NR a he haʻahaʻa ka hana wela. |
| Lke kū'ē ʻana i ka mahana
| ʻO ka mahana haʻahaʻa e maʻalahi ai ka paʻakikī (ʻo ka ʻino o ke kūlana, ʻo ke kiʻekiʻe o ka nui o ka styrene). | ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o Styrene NR i ke anu ma muli o ka mahana haʻahaʻa (-50°C e palupalu mau ana) |
| Ka hoʻopili ʻana o ka laholio | Pipili ponoʻī maikaʻi ʻole; pono ka hoʻohana ʻana i kahi resin hoʻonui adhesive. | Loaʻa iā NR nā waiwai hoʻopili ponoʻī maikaʻi loa. |
| Kumukūʻai | haʻahaʻa | Kiʻekiʻe aʻe (hoʻopilikia ʻia e ke aniau) |
He kūlana koʻikoʻi ko ka rubber Styrene-butadiene i ka ʻoihana huila, e hāʻawi ana i nā huila me ke kūpaʻa ʻana i ka ʻaʻahu, nā waiwai anti-kahiko a me ka paʻa maikaʻi loa. Eia kekahi, hoʻohana nui ʻia ia i: nā ʻāpana kaʻa (nā sila, nā mea hoʻokuʻu haʻalulu, a me nā mea ʻē aʻe), nā huahana ʻoihana (nā kāʻei conveyor, Apo Silas, etc.), nā mea kūkulu hale (nā pepa pale wai), nā lako lapaʻau (nā paipu laholio lapaʻau, nā mikina lima, a pēlā aku), nā mea hoʻopili a me nā uhi, a pēlā aku.
Nā mea hana nui o ka honua: Sinopec, PetroChina, Lanxess, Trinseo, Asahi Kasei, a pēlā aku.
ʻO nā ʻano huahana e komo pū me nā O-rings a me nā mea i hana ʻia no nā mea kūʻai aku.
