Vaega hydroxyl ta'itasi HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB fa'atasi ai ma se filifili e tasi o le hydroxyl -OH ma le fa'a-hydrogenated version
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Fa'amatalaga o oloa:
Igoa Vailaau: Vaega hydroxyl tasi HTPB / Hydroxyl-terminated polybutadiene
Fa'ailoga: HTPB-OH
CAS: 69102-90-5
fua fa'atatau:
Uiga: Saina Fa'atagaina Fa'atauina atu / HTPB laisene auina atu i fafo

O le HTPB o se polymer pipii mamao, o le pa'u vai fou. O meatotino e eseese ona o le HTPB o se paluga nai lo le mama mama, ma e gaosia e faʻafetaui manaoga faʻapitoa a tagata faʻatau. Ole HTPB masani ole R-45M fa'atasi ai ma pito ta'itasi ole filifili fa'amuta ile vaega ole hydroxyl [OH]. (PS: e mafai ona tatou faia so o se lomiga o le HTPB e pei ona talosaga tagata faatau, ma le mamanu fou le HTPB ma se filifili se tasi o hydroxyl -OH, I le taimi nei, e mafai ona tatou faia hydrogenation o le HTPB)
O le tasi hydroxyl vaega HTPB o se oloa polybutadiene ma vaega hydroxyl i le tasi pito, lea e mafai ona ausia faaluaina faamalologa o hydroxyl ma vinyl vaega. O loʻo i ai le maualuga o le gaioiga, sili ona lelei o le hydrophobicity ma mea dielectric, ma le lelei o le gaosiga o gaioiga.
O le HTPB o loʻo i ai le diaphaneity lelei, maualalo le viscosity, matua teteʻe, maualalo le vevela faʻatinoga, Hydrolysis teteʻe, acid ma alkali teteʻe, ofuina teteʻe ma mea sili ona lelei insulation eletise.
ma lelei galuega faatino. HTPB e mafai ona faʻaaogaina i:
- Fa'apipi'i
- Faamaufa'ailoga
- Polymers
- Mea fa'a'ese'ese eletise
- Mea e puipuia ai le vai ma le pala
- Ufiufi
- Mea fa'apipi'i Polyurethane
- oloa pa'u
- Suau'u malosi
- Fa'aolaola
- Pa'u ta'avale ma va'alele o mea fa'atulagaina
- Hydroxyl-terminated polybutadiene propellant(HTPB+AP+Al)
- Aerospace, Rockets ma Misile
- lubricating suauu
- ma isi ituaiga o faʻaoga.
afifiina:
Faʻapipiʻi i le 50kg / paʻu, 170kg / paʻu, O le taimi e teu ai e 1 tausaga.
Fa'atonuga mo le saogalemu:
O le teuina e tatau ona malu, mago ma ea. Ole tulaga sili ona lelei ile -20 ~ 38℃. E 12 masina le umi, pe a fa'amutaina, fa'aaoga pea pe a o'o i tulaga masani e ala i le toe su'ega. Pe a tatau ona aloese mai le timu, susulu o le la. Aua le fa'afefiloi ma le oxidizer malosi.
