Sehlopha sa hydroxyl se le seng HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB e nang le ketane e le 'ngoe ea hydroxyl -OH le mofuta oa hydrogenated
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Lintlha tsa sehlahisoa:
Lebitso la Khemik'hale: Sehlopha se le seng sa hydroxyl HTPB / Polybutadiene e fedisitsweng ke Hydroxyl
Khoutu: HTPB-OH
CAS: 69102-90-5
Mokgwa wa ho Lekanya:
Semelo: Laesense ea ho romela thepa kantle ho naha e lumelletsoeng ke China / laesense ea ho romela thepa kantle ho naha ea HTPB
Maemo: GB (Kereiti ea Sechaba) / GJB (Kereiti ea Sesole/ GJB 1327A-2003)
HTPB ke polymer ya claw e hole ya metsi, rabara e ntjha ya metsi. Dibopeho tsa yona di a fapana hobane HTPB ke motswako ho ena le motsoako o hlwekileng, mme e entswe ho fihlela ditlhoko tse ikgethang tsa bareki. HTPB e tlwaelehileng ke R-45M moo pheletso ka nngwe ya ketane e kgaolwang ka sehlopha sa hydroxyl [OH].PS: re ka etsa mefuta efe kapa efe ea HTPB kamoo bareki ba kopang, 'me ra rala HTPB e ncha ka ketane e le' ngoe ea hydroxyl -OH, Ha re ntse re le joalo, re ka etsa hydrogenation ea HTPB)
Sehlopha se le seng sa hydroxyl HTPB ke sehlahisoa sa polybutadiene se nang le lihlopha tsa hydroxyl pheletsong e 'ngoe, se ka finyellang ho fola habeli ha lihlopha tsa hydroxyl le vinyl. Se na le reactivity e phahameng, ho se tšabe metsi le thepa ea dielectric e ntle haholo, le ts'ebetso e ntle ea ts'ebetso.
HTPB e na le diaphaneity e ntle, viscosity e tlase, khanyetso ea botsofali, ts'ebetso e tlase ea mocheso, khanyetso ea Hydrolysis, khanyetso ea asiti le alkali, khanyetso ea ho tsofala le thepa e ntle ea ho kenya motlakase kahare.
'me ts'ebetso ea ts'ebetso e ntle. HTTPB e ka sebelisoa ho:
- Sekhomaretsi
- Litiiso
- Li-polymer
- Thepa ea ho thibela mocheso ea motlakase
- Thepa ea ho thibela metsi le ea tšireletso ea mafome
- Ho koahela
- Thepa ea polyurethane
- Lihlahisoa tsa rabara
- Mafura a tiileng
- Sefutho se tsamaisang motlakase
- Lithaere tsa thepa ea mohaho tsa likoloi le lifofane
- Sefutho sa polybutadiene se fedisitsweng ke hydroxyl (HTPB+AP+Al)
- Lifofane, Lirokete le Limisaele
- oli ea ho tlotsa
- le mefuta e mengata ea tšebeliso.
Ho paka:
E pakiloe ka 50kg/moropa, 170kg/moropa, Nako ea polokelo ke selemo se le seng.
Litaelo tsa polokeho:
Polokelo e lokela ho ba sebakeng se pholileng, se omileng le se nang le moea o kenang. Boemo bo botle ka ho fetisisa ke pakeng tsa -20 ~ 38℃. Nako ea ho boloka ke likhoeli tse 12, haeba e fela, e ntse e sebelisoa haeba e le maemong a tloaelehileng nakong ea tlhahlobo hape. Ha lipalangoang li lokela ho qoba pula, khanya ea letsatsi. U se ke ua kopanya le oxidizer e matla.
