Hydrogenated HTPB Hydrogenated Hydroxyl Ẹgbẹ-Polybutadiene ti pari
HydrogenatedHTPBHydrogenated Hydroxyl Ẹgbẹ-Polybutadiene ti pari
Awọn alaye ọja:
Orukọ Kemikali: HTPB Hydrogenated
Iru: Hydrogenated version
Fọọmu:
Ohun kikọ: Ilu China ti a fun ni aṣẹ Atajaja / Iwe-aṣẹ okeere HTPB
Boṣewa: GB (Ipe Ilu) / GJB (Ipele ologun/GJB 1327A-2003)
HTPB jẹ polima claw latọna jijin omi, roba omi tuntun. Awọn ohun-ini yatọ nitori HTPB jẹ adalu kuku ju agbo-ẹda mimọ, ati pe o jẹ iṣelọpọ lati pade awọn ibeere pataki ti awọn alabara. Aṣoju HTPB jẹ R-45M pẹlu opin kọọkan ti pq ti pari pẹlu ẹgbẹ hydroxyl [OH]. (PS: a le ṣe eyikeyi awọn ẹya ti HTPB bi awọn alabara beere, ati apẹrẹ tuntun HTPB pẹlu ẹwọn kan ti hydroxyl -OH, Nibayi, a le ṣe hydrogenation ti HTPB)
Fun HTPB Hydrogenated jẹ awọn homopolymers hydrogenated ti butadiene, wọn jẹ opin mejeeji ẹgbẹ hydroxyl ati pe o dara fun ọpọlọpọ awọn lilo. Nitori itẹlọrun ti ẹgbẹ 1,2-vinyl polybutadiene wọnyi ni iduroṣinṣin kemikali igba pipẹ to dara julọ.
Awọn ohun-ini bii:
Gíga rọ be
Hydrophobicity
Low dielectric ibakan
Ti o dara kemikali resistance
Awọn ẹgbẹ hydroxyl ifaseyin
Iduroṣinṣin igba pipẹ
Awọn oluyipada Resini, awọn resini urethane (awọn kikun, awọn adhesives, awọn aṣoju ibora), awọn ohun elo idabobo itanna, TPU elastomers
Iṣakojọpọ:
Ti kojọpọ ni 50kg / ilu, 170kg / ilu, Akoko ipamọ jẹ ọdun 1.
Awọn itọnisọna aabo:
Ibi ipamọ yẹ ki o wa ni itura, gbẹ ati ventilate. Ipo ti o dara julọ jẹ laarin -20 ~ 38 ℃. Igbesi aye selifu ti oṣu 12, ti o ba pari, tun lo ti o ba to iwọn nipasẹ atunwo. Nigba ti gbigbe yẹ ki o yago fun ojo, orun. Maṣe dapọ pẹlu oxidizer to lagbara.
