Hydrogenated Hydroxyl Group-Terminated Polybutadiene

Tlhaloso e Khutšoanyane:

HTTPB ke polymer ya claw e hole ya metsi, rabara e ntjha ya metsi. Thepa ya yona e 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 kgaotswang ka sehlopha sa hydroxyl [OH]. (PS: re ka etsa moralo o motjha jwalo ka HTPB ka ketane e le nngwe ya -OH ka nngwe le mofuta wa Hydrogenated).

Likaroloana

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)

Bakeng sa HTPB e nang le hydrogenated ke li-homopolymer tse nang le hydrogenated tsa butadiene, li felisitsoe ka bobeli ke sehlopha sa hydroxyl 'me li loketse mefuta e mengata ea ts'ebeliso. Ka lebaka la ho tlala ha sehlopha sa 1,2-vinyl, li-polybutadiene tsena li na le botsitso bo botle ba lik'hemik'hale ba nako e telele.
