HTPB Fa'a-Hydrogenated Hydroxyl Group-Fa'amuta Polybutadiene
Fa'a-hidrogenate HTPB Polybutadiene ua Fa'amutaina i le Hydrogenated Hydroxyl Group
Fa'amatalaga o oloa:
Igoa Fa'akemikolo: HTPB Fa'a-Haitorosene
Ituaiga: Fa'aliliuga fa'a-hydrogenate
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.)
Mo le Hydrogenated HTPB o ni hydrogenated homopolymers o le butadiene, e lua-iuga hydroxyl group-terminated ma e talafeagai mo le tele o faʻaoga. Ona o le saturation o le 1,2-vinyl group, o nei polibutadienes e iai le mautu lelei i se taimi umi.
Meatotino e pei o:
Fausaga e matua fetuutuunai
Fa'a'ese'esega mai le vai
Fa'aauau pea le dielectric maualalo
Tete'e lelei i vaila'au fa'akemikolo
Vaega hydroxyl tali atu
Mausali mo se taimi umi
Mea e fa'aleleia ai le resin, urethane resins (vali, mea fa'apipi'i, mea e ufiufi ai), mea e fa'amama ai le eletise, TPU elastomers
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.
