Eqoqweni elikhazimulayo lemboni yamakhemikhali, i-butadiene ngokungangabazeki iyinkanyezi ekhazimulayo. Iyigesi engenambala enephunga elimnandi. Kubonakala sengathi ivamile, empeleni iqukethe amandla amakhulu angashintsha umhlaba.
I-Butadiene ingabhekwa njenge-"superhero" embonini yerabha yokwenziwa. Amarabha ahlukahlukene asebenza kahle njengerabha ye-styrene-butadiene, irabha ye-cis-polybutadiene, irabha ye-nitrile-butadiene, kanye nerabha ye-chloroprene konke kuncike ku-butadiene, "umdali" oyinhloko. Kungakhathaliseki ukuthi ukumelana nokuguguleka nokubamba kwamathayi ezimoto ezimweni zomgwaqo eziyinkimbinkimbi noma ukuvikelwa okuthembekile kwezivalo zerabha ezindaweni ezimbi kakhulu, i-butadiene yenza iminikelo ethule ngemuva kwezigcawu.
Ngaphezu kwalokho, i-butadiene ikhanya kakhulu nasesiteji sama-resin epulasitiki. Ngokuthuthuka okunamandla kwemboni yepulasitiki ye-styrene, i-butadiene ne-styrene zisebenza ngokubambisana nge-copolymerization, ziveza uchungechunge "lwezinto zomlingo" ezinezicelo eziningi, njenge-ABS resin ne-SBS resin. Kusukela ezikhwameni eziqinile zemikhiqizo ye-elekthronikhi kuya ezingxenyeni ezinesitayela zangaphakathi kwezimoto, la ma-resin asebenza kahle kakhulu anika imikhiqizo ikhwalithi enhle kakhulu ngenxa yezakhiwo zayo ezivelele.
Njengezinto ezibalulekile eziyisisekelo zamakhemikhali, "ukufinyelela" kwe-butadiene kufinyelela nasekukhiqizweni kwamakhemikhali abalulekile njenge-ethylidene norbornene, i-1,4-butanediol, ne-adiponitrile. Le mikhiqizo iguqulwa ibe yipulasitiki yobunjiniyela, i-nylon 66, njll., ezisetshenziswa kabanzi emikhakheni ephezulu njengezindiza kanye nokukhiqizwa kwemishini, okuba amandla abalulekile aqhuba intuthuko yemboni yanamuhla.
Emkhakheni wamakhemikhali amahle, i-butadiene ikhombisa ubuhle bayo obuyingqayizivele nakakhulu. Ama-derivatives e-anthraquinone akhiwa ukusabela ngama-compounds e-dieneophile aswele ama-electron ayizinto ezibalulekile ezihlanganisa udayi, ama-fungicides, kanye ne-insecticide. I-anhydride ye-tetrahydrophthalic etholakala ngokusabela ngama-anhydride e-maleic ingasetshenziswa njenge-ejenti yokwelapha kanye ne-plasticizer yama-resin e-polyester nama-resin epoxy, okufaka amandla amasha ekuthuthukiseni izakhiwo zezinto ezibonakalayo.
Ukukhetha i-butadiene kusho ukukhetha ukusungula izinto ezintsha kanye nekhwalithi, nokukhetha ukuvula amathuba angenamkhawulo okusungula izinto ezintsha kwezimboni ezahlukahlukene! Masibambisane futhi sakhe ikusasa elingcono embonini yamakhemikhali, i-butadiene njengesisekelo.
