Hoʻokahi pūʻulu hydroxyl 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 polybutadiene CAS: 69102-90-5
Nā kikoʻī huahana:
Inoa Kemika: Hoʻokahi hui hydroxyl HTPB / Hydroxyl-terminated polybutadiene
Code: HTPB-OH
CAS: 69102-90-5
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)
ʻO ka hui hydroxyl hoʻokahi HTPB he huahana polybutadiene me nā pūʻulu hydroxyl ma kahi hopena, 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.
He diaphaneity maikaʻi ka HTPB, haʻahaʻa haʻahaʻa, kūʻokoʻa kūʻokoʻa, hana haʻahaʻa haʻahaʻa, Hydrolysis resistance, acid and alkali resistance, wear resistance and good electrical insulation properties
a maikaʻi ka hana hoʻoponopono. Hiki ke hoʻohana ʻia ka HTPB i:
- Hoʻopili
- Na sila
- Polimer
- Nā mea hoʻoheheʻe uila
- Nā mea pale wai a me ka corrosion
- Ka uhi
- Nā mea polyurethane
- Nā huahana Rubber
- Ka wahie paʻa
- Mea hoʻolalelale
- Nā huila kaʻa a me nā mokulele o nā mea hana
- Hoʻopau i ka hydroxyl polybutadiene propellant (HTPB+AP+Al)
- Aerospace, Rockets a me Missile
- nā aila lubricating
- a pēlā aku nā ʻano hoʻohana he nui.
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.
