HTPB, e tsejoang hape e le hydroxyl-terinated polybutadiene, ke polymer e tsebahalang liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le ho feto-fetoha ha maemo. Sehloohong sena, re tla hlahloba lits'ebetso le ts'ebeliso e fapaneng ea HTPB.
HTPB ke rabara ea maiketsetso e entsoeng ka polymerized ho tloha butadiene le tekanyo e nyenyane ea divinylbenzene. Lintho tse hlahisoang li khetholloa ke hydroxyl (-OH) termini, e fanang ka lintho tse ngata tse lakatsehang ho polymer.
E 'ngoe ea litšebeliso tsa bohlokoa ka ho fetisisa tsa HTPB ke tšimong ea li-rocket propellants. Polymer ena e sebelisoa haholo e le motsoako oa bohlokoa tlhahisong ea mafura a rocket motor. Li-propellants tse thehiloeng ho HTPB li fana ka melemo e mengata ho feta mekhoa e meng. Li-propellants tsena ha li amehe haholo ha li tšosoa le ho tšoha, li netefatsa polokeho e eketsehileng nakong ea ho ts'oaroa le lipalangoang. Ho phaella moo, li bontša mekhoa e metle ea mechine, e kang elasticity e ntle le ho feto-fetoha ha maemo, e lumellang propellant hore e mamelle khatello e phahameng le ho potlakisa nakong ea mollo. Ntle le moo, li-propellants tse thehiloeng ho HTPB li na le tšusumetso e itseng e batlang e phahame, e thusang ho fihlela sepheo se seholo le katleho ho propulsion ea rocket.
Ntle le lits'ebetso tsa sepakapaka, HTPB e sebelisetsoa ho etsa li-elastomer le li-sealants tse fapaneng. Ka lebaka la khanyetso e ntle ea lik'hemik'hale, HTPB e atisa ho sebelisoa e le tlamahano ha ho etsoa li-adhesives le liphahlo. Bokhoni ba eona ba ho khomarela mefuta e fapaneng ea li-substrates bo e etsa khetho ea pele bakeng sa lits'ebetso tse hlokang tlamahano e matla. Ho phaella moo, li-sealants tse thehiloeng ho HTPB li ka sebelisoa bakeng sa ho tiisa moea le metsi ka har'a liindasteri tse kang tsa kaho le tsa likoloi. Li-sealants tsena li tsebahala ka ho tšoarella ha tsona le ho hanyetsa mocheso o feteletseng le maemo a thata a tikoloho.
Sebaka se seng mooHTPB e bapala karolo ea bohlokoa tlhahisong ea lihlahisoa tsa foam tse tenyetsehang. Polymer ena e sebelisoa ho etsa foam e sebelisoang liindastering tse fapaneng, ho kenyeletsoa likoloi, sebaka sa sefofane le sepakapaka. Foams tse thehiloeng ho HTPB li na le thepa e ntle haholo ea ho ts'oara 'me li loketse ho sebelisoa materaseng, li-cushion tsa litulo le lisebelisoa tse monyang maikutlo. Ho feto-fetoha ha maemo a HTPB ho lumella ho hlahisa liforomo tsa mefuta e fapaneng ea density le hardness ho fihlela litlhoko tse fapaneng tsa kopo.
Indasteri ea ts'ireletso e boetse e rua molemo ho sebelisoa ha HTPB bakeng sa tlhahiso ea liqhomane.HTPB liqhomane li sebelisoa lihlomong tsa lithunya, likhetla tsa lithunya le mefuta e meng e fapaneng. Liqhomane tsena li na le thepa e lakatsehang joalo ka tlhahiso e phahameng ea matla, botsitso le ho hloka kutlo ho ts'usumetso, ho etsa hore li tšoanelehe bakeng sa lits'ebetso tsa sesole.
Ho phaella moo, HTPB e sebelisoa ha ho etsoa liaparo tse khethehileng le lipente. Liaparo tsena li sebelisoa haholo liindastering moo tšireletso khahlanong le ho bola le ho pepeseha ha tikoloho ho le bohlokoa, joalo ka liindasteri tsa oli le khase, tsa metsing le tsa likoloi. Ho hanyetsa ha HTPB ho lik'hemik'hale le maemo a thata ho tiisa hore ho roala ho fana ka tšireletso ea nako e telele, e ka tšeptjoang.
Ka bokhutšoanyane, HTPB ke polymer e nang le mekhoa e mengata e ka sebelisoang liindastering tse ngata. Ho tloha ho li-rocket propellants ho ea ho li-sealants, foams, liqhomane le liphahlo, thepa e ikhethang ea HTPB e etsa hore e be khetho e babatsehang bakeng sa mefuta e fapaneng ea lisebelisoa. Ha theknoloji e ntse e tsoela pele, tlhokahalo ea HTPB e lebelletsoe ho tsoela pele ho hola mme lits'ebetso tse ncha tsa polymer ena e makatsang li tla hlaha.
