Hydrogenated HTPB Hydrogenated Hydroxyl Itsinda-Ryarangiye Polybutadiene
HydrogenatedHTPBHydrogenated Hydroxyl Itsinda-Ryarangiye Polybutadiene
Ibisobanuro birambuye:
Izina ryimiti: Hydrogenated HTPB
Ubwoko: verisiyo ya hydrogenated
Inzira ：
Imiterere: Ubushinwa bwemerewe kohereza ibicuruzwa hanze / HTPB uruhushya rwo kohereza hanze
Igipimo: GB (Grade Grade) / GJB (Icyiciro cya Gisirikare / GJB 1327A-2003)
HTPB numuyoboro wa kure wa claw polymer, reberi nshya. Imiterere iratandukanye kuko HTPB nuruvange aho kuba uruvange rwiza, kandi rwakozwe kugirango rwuzuze ibyo abakiriya bakeneye. Ubusanzwe HTPB ni R-45M hamwe na buri mpera yumunyururu urangizwa nitsinda rya hydroxyl [OH]. (PS: dushobora gukora verisiyo iyo ari yo yose ya HTPB nkuko abakiriya babisabye, kandi igishushanyo gishya cya HTPB hamwe numurongo umwe wa hydroxyl -OH, Hagati aho, dushobora gukora hydrogenation ya HTPB)
Kuri Hydrogenated HTPB ni hydrogenated homopolymers ya butadiene, byombi birangira hydroxyl itsinda ryarangiye kandi rikwiriye gukoreshwa muburyo butandukanye. Bitewe no kwiyuzuza kwitsinda rya 1,2-vinyl aba polybutadienes bafite imiti ihamye yigihe kirekire.
Ibyiza nka:
Imiterere ihindagurika cyane
Hydrophobicity
Umuyoboro muke uhoraho
Kurwanya imiti myiza
Amatsinda meza ya hydroxyl
Iterambere rirambye
Guhindura resin, urethane isiga (amarangi, ibifunga, ibikoresho byo gutwikira), ibikoresho bitanga amashanyarazi, TPU elastomers
Gupakira:
Gupakira muri 50kg / ingoma, 170kg / ingoma, Igihe cyo kubika ni umwaka 1.
Amabwiriza yumutekano:
Ububiko bugomba kuba bukonje, bwumutse kandi buhumeka. Imiterere myiza iri muri -20 ~ 38 ℃. Ubuzima bwa Shelf bwamezi 12, niba burangiye, buracyakoreshwa niba kugeza kurwego rusanzwe. Iyo ubwikorezi bugomba kwirinda imvura, izuba. Ntukavange na okiside ikomeye.
