Butadiene: Zinthu Zapadera Zotsegula Luso la Makampani Osiyanasiyana

Mu gulu la nyenyezi lowala kwambiri la makampani opanga mankhwala, butadiene mosakayikira ndi nyenyezi yowala kwambiri. Ndi mpweya wopanda mtundu wokhala ndi fungo lonunkhira pang'ono. Ngakhale kuti imawoneka ngati yachilendo, kwenikweni ili ndi mphamvu zambiri zomwe zimatha kusintha dziko lapansi.

Butadiene imatha kuonedwa ngati "ngwazi yayikulu" mumakampani opanga rabala. Ma rabala osiyanasiyana ogwira ntchito bwino monga rabala ya styrene-butadiene, rabala ya cis-polybutadiene, rabala ya nitrile-butadiene, ndi rabala ya chloroprene zonse zimadalira butadiene, "wopanga" wamkulu. Kaya ndi kukana kuwonongeka ndi kugwira kwa matayala agalimoto pamsewu wovuta kapena chitetezo chodalirika cha zisindikizo za rabala m'malo ovuta kwambiri, butadiene imapereka chithandizo chachinsinsi kumbuyo kwa zochitika.

Kuphatikiza apo, butadiene imawalanso kwambiri pa siteji ya ma resin apulasitiki. Ndi chitukuko champhamvu cha makampani opanga pulasitiki a styrene, butadiene ndi styrene zimagwira ntchito limodzi kudzera mu copolymerization, zomwe zimapangitsa kuti pakhale "zipangizo zamatsenga" zomwe zimagwiritsidwa ntchito kwambiri, monga resin ya ABS ndi resin ya SBS. Kuyambira pazitseko zolimba za zinthu zamagetsi mpaka zinthu zokongola zamkati mwa magalimoto, ma resin awa ogwira ntchito kwambiri amapereka zinthu zabwino kwambiri chifukwa cha mawonekedwe awo abwino.

Monga mankhwala ofunikira kwambiri, "kufikira" kwa butadiene kumafikiranso pakupanga mankhwala ofunikira monga ethylidene norbornene, 1,4-butanediol, ndi adiponitrile. Zinthuzi zimasinthidwanso kukhala mapulasitiki auinjiniya, nayiloni 66, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri m'magawo apamwamba monga kupanga ndege ndi makina, kukhala mphamvu yofunika kwambiri yomwe ikuyendetsa patsogolo makampani amakono.

Mu mankhwala abwino, butadiene imasonyeza kukongola kwake kwapadera kwambiri. Ma anthraquinone ochokera ku anthraquinone omwe amapangidwa ndi reaction ndi ma elekitironi omwe alibe ma elekitironi ndi ofunikira kwambiri pa utoto, fungicides, ndi tizilombo toyambitsa matenda. Tetrahydrophthalic anhydride yomwe imapezeka ndi reaction ndi maleic anhydride ingagwiritsidwe ntchito ngati chochiritsira komanso pulasitiki ya ma polyester resins ndi ma epoxy resins, zomwe zimapangitsa kuti zinthu zikhale bwino.

Kusankha butadiene kumatanthauza kusankha luso ndi ubwino, ndikusankha kutsegula mwayi wopanda malire wa luso la mafakitale osiyanasiyana! Tiyeni tigwirizane ndikumanga tsogolo labwino la makampani opanga mankhwala ndi butadiene ngati mwala wapangodya.
