Butadiene: He Mea Maka Kilokilo e Wehe ana i ka Hana Hou o nā ʻOihana like ʻole

I loko o ka hōkū ʻālohilohi o ka ʻoihana kemika, he hōkū ʻālohilohi loa ka butadiene. He kinoea kala ʻole ia me kahi ʻala ʻala iki. Me he mea lā he mea maʻamau, aia i loko ka ikehu nui e hiki ke hoʻololi i ke ao nei.

Hiki ke manaʻo ʻia ʻo Butadiene ʻo ia ka "superhero" i ka ʻoihana rubber synthetic. ʻO nā rubber hana kiʻekiʻe like ʻole e like me ka styrene-butadiene rubber, cis-polibutadiene rubber, nitrile-butadiene rubber, a me ka chloroprene rubber e hilinaʻi nei i ka butadiene, ke "mea hana" nui. Inā paha ʻo ia ke kūpaʻa ʻana i ka ʻaʻahu a me ka paʻa ʻana o nā kaila kaʻa ma nā kūlana alanui paʻakikī a i ʻole ka palekana hilinaʻi o nā sila rubber i nā wahi koʻikoʻi, hāʻawi ka butadiene i nā hāʻawi leo ʻole ma hope o nā hiʻohiʻona.

Eia kekahi, ʻālohilohi pū ka butadiene ma ke kahua o nā resins plastik. Me ka hoʻomohala ikaika ʻana o ka ʻoihana plastik styrene, hana pū ka butadiene a me ka styrene ma o ka copolymerization, e hānau ana i kahi moʻo o nā "mea kilokilo" me nā noi ākea, e like me ka resin ABS a me ka resin SBS. Mai nā pahu paʻa o nā huahana uila a hiki i nā ʻāpana kaila o nā loko kaʻa, hāʻawi kēia mau resins hana kiʻekiʻe i nā huahana me ka maikaʻi maikaʻi loa ma muli o ko lākou mau waiwai koʻikoʻi.

Ma ke ʻano he mea maka kemika kumu koʻikoʻi, ua pālahalaha aku ka "hiki" o ka butadiene i ka hana ʻana i nā kemika koʻikoʻi e like me ka ethylidene norbornene, 1,4-butanediol, a me ka adiponitrile. Hoʻololi hou ʻia kēia mau huahana i nā plastics ʻenekinia, nylon 66, a me nā mea ʻē aʻe, i hoʻohana nui ʻia ma nā kahua kiʻekiʻe e like me ka aerospace a me ka hana mīkini, e lilo ana i mea ikaika nui e hoʻokele ana i ka holomua o ka ʻoihana hou.

Ma ke kahua o nā kemika maikaʻi, hōʻike nui ka butadiene i kona ʻano hoʻohiwahiwa kū hoʻokahi. ʻO nā derivatives anthraquinone i hoʻokumu ʻia e ka hopena me nā hui dieneophile nele i ka electron he mau mea waena koʻikoʻi no nā dyes, fungicides, a me nā insecticides. Hiki ke hoʻohana ʻia ka tetrahydrophthalic anhydride i loaʻa ma ka hopena me ka maleic anhydride ma ke ʻano he mea hoʻōla a me ka plasticizer no nā resins polyester a me nā resins epoxy, e hoʻokomo ana i ka ikaika hou i ka hoʻomaikaʻi ʻana i nā waiwai o nā mea.

ʻO ke koho ʻana i ka butadiene ke koho ʻana i ka hana hou a me ka maikaʻi, a me ke koho ʻana e wehe i nā hiki palena ʻole o ka hana hou o nā ʻoihana like ʻole! E hui pū kākou a kūkulu i kahi wā e hiki mai ana no ka ʻoihana kemika me ka butadiene ma ke ʻano he kihi.
