I-HTPB yipolymer ye-claw ekude yolwelo, irabha entsha yolwelo. Iimpawu zahlukile kuba i-HTPB ngumxube endaweni yokuba yi-compound ecocekileyo, kwaye yenziwe ukuze ihlangabezane neemfuno ezithile zabathengi. I-HTPB eqhelekileyo yi-R-45M apho isiphelo ngasinye sekhonkco siphela ngeqela le-hydroxyl [OH].PS: singenza naziphi na iinguqulelo ze-HTPB njengoko abathengi becela, kwaye siyile i-HTPB entsha ngomxokelelwane omnye we-hydroxyl -OH, Okwangoku, singenza i-hydrogenation ye-HTPB)
Iqela le-single hydroxyl HTPB yimveliso ye-polybutadiene enamaqela e-hydroxyl kwelinye icala, enokufezekisa ukuphiliswa kabini kwamaqela e-hydroxyl kunye ne-vinyl. Ine-reactivity ephezulu, i-hydrophobicity egqwesileyo kunye neempawu ze-dielectric, kunye nokusebenza kakuhle kokucubungula.
I-HTPB inobukhulu obuhle, i-viscosity ephantsi, iyamelana nokwaluphala, isebenza kakuhle kubushushu obuphantsi, iyamelana ne-hydrolysis, iyamelana ne-asidi kunye ne-alkali, iyamelana nokuguguleka kunye neempawu ezintle zokufakelwa kombane.
kwaye ukusebenza kakuhle kokucubungula. I-HTTPB ingasetyenziswa kwi:
- Incamathelisa
- Izinto zokutywina
- IiPolymers
- Izixhobo zokukhusela umbane
- Izixhobo zokukhusela ukungenwa kwamanzi kunye nokugqwala
- Ukwaleka
- Izinto zePolyurethane
- Iimveliso zerabha
- Ipetroli eqinileyo
- Into eqhubayo
- Amatayara eemoto neeplani enziwe ngezinto zokwakha
- I-propellant ye-polybutadiene epheliswe yi-hydroxyl (HTPB+AP+Al)
- Inqwelo-moya, iiRokethi kunye neeMissile
- iioyile zokuthambisa
- njalo njalo kwiintlobo ezininzi zokusetyenziswa.
Ukupakisha:
Ipakishwe kwi-50kg/drum, i-170kg/drum, ixesha lokugcina liyi-1 ngonyaka.
Imiyalelo yokhuseleko:
Indawo yokugcina kufuneka ibe kwindawo epholileyo, eyomileyo kwaye iphefumle umoya. Imeko engcono iphakathi kwe -20 ~ 38℃. Ixesha lokugcinwa kweshelufu leenyanga ezili-12, ukuba liphelile, lingasetyenziswa ukuba lisemgangathweni xa livavanywa kwakhona. Xa uthutho kufuneka uphephe imvula, ukukhanya kwelanga. Musa ukuxuba ne-oxidizer enamandla.
