Butadiene: Thepa e Tala ea Boselamose e Notlollang Boqapi ba Liindasteri tse Fapaneng

Sehlopha se setle sa indasteri ea lik'hemik'hale, butadiene ha ho pelaelo hore ke naleli e benyang. Ke khase e se nang 'mala e nang le monko o monate o fokolang. E bonahala e tloaelehile, ha e le hantle e na le matla a maholo a khonang ho fetola lefatše.

Butadiene e ka nkoa e le "mohale ea matla" indastering ea rabara ea maiketsetso. Liraba tse fapaneng tse sebetsang hantle joalo ka rabara ea styrene-butadiene, rabara ea cis-polybutadiene, rabara ea nitrile-butadiene, le rabara ea chloroprene kaofela li itšetlehile ka butadiene, "moetsi" oa mantlha. Ebang ke ho hanyetsa ho tsofala le ho tšoara ha mabili a likoloi maemong a rarahaneng a litsela kapa tšireletso e tšepahalang ea litiiso tsa rabara libakeng tse feteletseng, butadiene e etsa menehelo e khutsitseng ka morao ho liketsahalo.

Ho feta moo, butadiene e boetse e khanya haholo sethaleng sa li-resin tsa polasetiki. Ka nts'etsopele e matla ea indasteri ea polasetiki ea styrene, butadiene le styrene li sebetsa 'moho ka copolymerization, li hlahisa letoto la "lisebelisoa tsa boselamose" tse nang le lits'ebetso tse pharaletseng, joalo ka resin ea ABS le resin ea SBS. Ho tloha likheong tse tiileng tsa lihlahisoa tsa elektroniki ho isa likarolong tse ntle tsa kahare tsa likoloi, li-resin tsena tse sebetsang hantle li fa lihlahisoa boleng bo botle ka lebaka la thepa ea tsona e ikhethang.

Jwalo ka thepa ya bohlokwa ya motheo ya dikhemikhale tse tala, "phihlello" ya butadiene e boetse e atolohela tlhahisong ya dikhemikhale tsa bohlokwa tse kang ethylidene norbornene, 1,4-butanediol, le adiponitrile. Dihlahiswa tsena di fetolwa hape ho ba polasetiki ya boenjiniere, nylon 66, jj., tse sebediswang haholo masimong a maemo a hodimo jwalo ka aerospace le tlhahiso ya mechini, e leng matla a bohlokwa a kgannang kgatelopele ya indasteri ya sejwalejwale.

Lefapheng la lik'hemik'hale tse ntle, butadiene e bontša botle ba eona bo ikhethang le ho feta. Li-derivative tsa anthraquinone tse entsoeng ke karabelo e nang le metsoako ea dieneophile e haelloang ke li-electron ke lintho tsa bohlokoa tse kopanyang dae, li-fungicide le likokoanyana tse bolaeang likokoanyana. Anhydride ea tetrahydrophthalic e fumanoeng ke karabelo e nang le anhydride ea maleic e ka sebelisoa e le sesebelisoa sa ho folisa le plasticizer bakeng sa li-resin tsa polyester le li-resin tsa epoxy, e kenyang matla a macha ntlafatsong ea thepa ea thepa.

Ho khetha butadiene ho bolela ho khetha boqapi le boleng, le ho khetha ho notlolla menyetla e sa feleng ea boqapi ba liindasteri tse fapaneng! A re kopaneng 'me re hahe bokamoso bo betere bakeng sa indasteri ea lik'hemik'hale ka butadiene e le lejoe la motheo.
