HTPB Hydrogenated Hydroxyl Group-Hoʻopau Polybutadiene
HoʻohāhāHTPBHoʻopau ʻia ka Polybutadiene i hoʻopau ʻia i ka hui Hydrogenated Hydroxyl Group
Nā kikoʻī huahana:
Inoa Kemika: Hydrogenated HTPB
ʻAno: Manaʻo Hydrogenated
Kumu:
ʻAno: Kina ʻae ʻia ka mea hoʻopuka / HTPB laikini hoʻopuka
Kūlana maʻamau: GB (Civil Grade) / GJB (Military Grade/ GJB 1327A-2003)
ʻO ka HTPB kahi polymer claw mamao wai, ka ʻōpala wai hou. ʻOkoʻa nā waiwai no ka mea he hui ʻia ʻo HTPB ma mua o kahi hui maʻemaʻe, a ua hana ʻia ia e hoʻokō i nā koi kikoʻī o nā mea kūʻai aku. ʻO ka HTPB maʻamau ʻo R-45M me kēlā me kēia hopena o ke kaulahao i hoʻopau ʻia me kahi hui hydroxyl [OH]. (PS: hiki iā mākou ke hana i nā mana o ka HTPB e like me ke noi a nā mea kūʻai aku, a me ka hoʻolālā hou i ka HTPB me kahi kaulahao hoʻokahi o hydroxyl -OH, I kēia manawa, hiki iā mākou ke hana hydrogenation o ka HTPB)
No ka Hydrogenated HTPB he hydrogenated homopolymers o ka butadiene, ua pau ia i ka hui hydroxyl-hopena a kupono no ka hoohana nui ana. Ma muli o ka saturation o ka hui 1,2-vinyl i kēia mau polybutadienes i loaʻa i ka paʻa kemika lōʻihi loa.
Nā waiwai e like me:
ʻO ka hoʻolālā hikiwawe loa
Hydrophobicity
Haʻahaʻa dielectric mau
Kūleʻa kemika maikaʻi
Nā hui hydroxyl reactive
Paʻa lōʻihi
ʻO nā mea hoʻololi Resin, urethane resins (nā pena, nā mea hoʻopili, nā mea hoʻopili), nā mea hoʻokalakupua uila, TPU elastomers
Hoʻopili:
Hoʻopili ʻia ma 50kg / pahu, 170kg / pahu, ʻO ka manawa mālama he 1 makahiki.
Nā ʻōlelo aʻoaʻo palekana:
Pono ka waiho ʻana ma kahi anuanu, maloʻo a ventilate. ʻO ke kūlana maikaʻi loa ma waena o -20 ~ 38 ℃. He 12 mahina ke ola o ka waihona, inā pau, hoʻohana mau ʻia inā kū i ka maʻamau ma o ka hoʻāʻo hou ʻana. Ke pale aku ka lawe ʻana i ka ua, ka lā. Mai hui pū me ka oxidizer ikaika.
