Vaega hydroxyl e tasi HTPB CAS 69102-90-5 Polybutadiene ua fa'amutaina i le Hydroxyl HTPB fa'atasi ai ma se filifili e tasi o le hydroxyl -OH ma le fa'ata'ita'iga hydrogenated
HTPB / Hydroxyl-terminated polibutadiene CAS: 69102-90-5
Fa'amatalaga o oloa:
Igoa Fa'akemikolo: Vaega hydroxyl e tasi HTPB / Hydroxyl-terminated polibutadiene
Fa'ailoga: HTPB-OH
CAS: 69102-90-5
Fua fa'atatau：
Uiga: Laisene auina atu i fafo e le kamupani Saina ua faatagaina / HTPB
Tulaga Fa'atonu: GB (Vasega Sivili) / GJB (Vasega Fa'amiliteli/ GJB 1327A-2003)
O le HTPB o se polymer vai mamao, o le pa'u vai fou. E eseese ona meatotino ona o le HTPB o se paluga nai lo se mea mama, ma ua gaosia e fa'afetaui ai mana'oga fa'apitoa a tagata fa'atau. O se HTPB masani o le R-45M ma pito ta'itasi o le filifili e fa'ai'u i se vaega hydroxyl [OH].PS: e mafai ona matou faia so'o se fa'aliliuga o le HTPB e pei ona talosagaina e tagata fa'atau, ma le mamanu fou o le HTPB i se filifili e tasi o le hydroxyl -OH, I le taimi nei, e mafai ona matou faia le hydrogenation o le HTPB.)
O le vaega hydroxyl e tasi le HTPB o se oloa polybutadiene ma vaega hydroxyl i le tasi pito, lea e mafai ona fa'amālūlūina fa'alua vaega hydroxyl ma vinyl. E maualuga lona tali vave, sili ona lelei le hydrophobicity ma le dielectric properties, ma lelei le fa'agaioiga o le fa'agasologa.
E lelei le diaphaneity o le HTPB, maualalo le viscosity, tete'e atu i le matua, maualalo le fa'atinoga o le vevela, tete'e atu i le hydrolysis, tete'e atu i le acid ma le alkali, tete'e atu i le ofuina ma meatotino lelei tele o le insulation eletise.
ma lelei le fa'atinoga o le fa'agasologa. E mafai ona fa'aogaina le HTPB i:
- Fa'apipi'i
- Mea fa'amaufa'ailoga
- Polymers
- Mea e fa'amafanafana ai le eletise
- Mea e puipuia ai le ea ma le pala
- Ufiufi
- Meafaitino Polyurethane
- Oloa pa'u
- Suau'u malo
- Mea fa'aola
- Pa'u o ta'avale ma va'alele o mea faufale
- O le propellant polibutadiene ua fa'amutaina i le hydroxyl (HTPB+AP+Al)
- Vaalele i le ea, roketi ma le misila
- suāuu fa'a'asu
- ma isi mea faapena i le tele o ituaiga o faaaogaina.
afifiina:
Fa'aputuina i le 50kg/talipalau, 170kg/talipalau, O le vaitaimi e teu ai e 1 tausaga.
Fa'atonuga mo le saogalemu:
E tatau ona teuina i se nofoaga malūlū, mago ma lelei mo le ea. O le tulaga sili ona lelei o le -20 ~ 38℃. E 12 masina le umi e teu ai, afai e uma le aso, e mafai ona faʻaaogaina pe afai e tusa ai ma tulaga masani ma toe faia se suʻega. A o felauaiga e tatau ona ʻaloʻese mai le timu ma le susulu o le la. Aua neʻi faʻafefiloi ma se vailaʻau faʻaola malosi.
