Hui hydroxyl hoʻokahi HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB me kahi kaulahao hoʻokahi o ka hydroxyl -OH a me ka mana hydrogenated
HTPB / Hydroxyl-terminated polibutadiene CAS: 69102-90-5
Nā kikoʻī huahana:
Inoa Kemika: Hui hydroxyl hoʻokahi HTPB / Hydroxyl-terminated polibutadiene
Kōmike: HTPB-OH
CAS: 69102-90-5
Haʻilula
ʻAno: Laikini hoʻokuʻu aku i ʻae ʻia e Kina / laikini hoʻokuʻu aku HTPB
Kūlana: GB (Pae Kīwila) / GJB (Pae Koa/ GJB 1327A-2003)
He polymer ʻūlū mamao wai ka HTPB, ʻo ia ka laholio wai hou. ʻOkoʻa nā waiwai no ka mea he hui ʻana ka HTPB ma mua o kahi hui maʻemaʻe, a ua hana ʻia e hoʻokō i nā koi kikoʻī o nā mea kūʻai aku. ʻO kahi 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 kekahi mana o HTPB e like me ke noi a nā mea kūʻai aku, a hoʻolālā hou i ka HTPB me kahi kaulahao hoʻokahi o hydroxyl -OH, I kēia manawa, hiki iā mākou ke hana i ka hydrogenation o ka HTPB)
ʻO ka hui hydroxyl hoʻokahi HTPB kahi huahana polibutadiene me nā hui hydroxyl ma kekahi ʻaoʻao, hiki ke hoʻokō i ka hoʻōla pālua o nā hui hydroxyl a me vinyl. Loaʻa iā ia ka reactivity kiʻekiʻe, hydrophobicity maikaʻi loa a me nā waiwai dielectric, a me ka hana hana maikaʻi.
Loaʻa iā HTPB ka diaphaneity maikaʻi, ka viscosity haʻahaʻa, ke kūpaʻa ʻelemakule, ka hana haʻahaʻa haʻahaʻa, ke kūpaʻa Hydrolysis, ke kūpaʻa waikawa a me ka alkali, ke kūpaʻa ʻaʻahu a me nā waiwai insulation uila maikaʻi loa
a maikaʻi ka hana hana. Hiki ke hoʻohana ʻia ʻo HTPB i loko o:
- Hoʻopili
- Nā mea sila
- Nā Polymers
- Nā mea hoʻokaʻawale uila
- Nā mea pale wai a me ka pale ʻana i ka palaho
- Uhi ʻana
- Nā mea polyurethane
- Nā huahana laholio
- Wahie paʻa
- Mea hoʻoulu
- Nā huila kaʻa a me nā mokulele o nā mea kūkulu hale
- Mea hoʻoulu polibutadiene i hoʻopau ʻia e Hydroxyl (HTPB+AP+Al)
- Aerospace, Rockets a me Missile
- nā ʻaila hoʻoluʻu
- a pēlā aku nā ʻano hoʻohana he nui.
Hoʻopili ʻana:
Hoʻopaʻa ʻia i loko o 50kg/pahu, 170kg/pahu, ʻO ka manawa mālama he 1 makahiki.
Nā kuhikuhi palekana:
Pono e mālama ʻia ma kahi anuanu, maloʻo a me ka ea. ʻO ke kūlana maikaʻi loa ma waena o -20 ~ 38℃. ʻO ke ola o ka papa he 12 mau mahina, inā pau, e hoʻohana mau ʻia inā kū i ke kūlana ma o ka hoʻāʻo hou ʻana. I ka wā e lawe ai, pono e pale i ka ua a me ka lā. Mai hoʻohuihui me ka oxidizer ikaika.
