Hydrogenated HTPB Hydrogenated Hydroxyl Group-Terminated Polybutadiene
Fa'asalainaHTPBHydrogenated Hydroxyl Group-Terminated Polybutadiene
Fa'amatalaga o oloa:
Igoa vaila'au: Hydrogenated HTPB
Ituaiga: Fa'asusu fa'asusu
fua fa'atatau:
Uiga: Saina Fa'atagaina Fa'atauina atu / HTPB laisene auina atu i fafo
Tulaga: GB (Vaega Sivili) / GJB (Vaega Militeri/ GJB 1327A-2003)
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)
Mo Hydrogenated HTPB o homopolymers hydrogenated o le butadiene, o i latou uma e lua-i'uga hydroxyl vaega-fa'amuta ma talafeagai mo le tele o fa'aoga. Ona o le saturation o le 1,2-vinyl vaega o nei polybutadienes o loʻo maua ai le faʻamautuina o vailaʻau umi umi.
Meatotino e pei o:
Fa'atonuga maualuga
Hydrophobicity
Maualalo dielectric faifai pea
Lelei le tetee atu i kemikolo
Reactive hydroxyl vaega
Tulaga tumau
Resin modifiers, urethane resins (vali, faʻapipiʻi, mea faʻapipiʻi), mea eletise eletise, elastomers TPU
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.
