CAS 69102-90-5 HTPB Polybutadiene e fedisitsweng ke Hydroxyl HTPB bakeng sa propellant, likhomaretsi, li-sealant, le lipente

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)

Eona le moemeli oa katoloso ea ketane, moemeli oa ho hokahanya mochesong oa kamore kapa karabelo ea mocheso o phahameng li ka hlahisa sebopeho sa marang-rang a 3D sa litaba tsa ho folisa. Litaba tsa ho folisa li na le thepa e ntle ea mechini, haholo-holo khanyetso e ntle ho hydrolysis, khanyetso ea asiti le alkali, khanyetso ea ho tsofala, khanyetso e tlase ea mocheso le khanyetso e ntle ea motlakase.

Li-polyurethane tse lokisitsoeng ho tsoa ho HTPB li ka etsoa bakeng sa thepa e itseng ea 'mele; li-polyurethane li ka ba tse tenyetsehang haholo kapa tse thata le tse tiileng. Lihlahisoa tse ling li kenyelletsa: liphanele tse thata tsa ho thibela foam; mabili le lithaere tse tšoarellang tsa elastomeric (tse sebelisoang bakeng sa li-roller coaster, li-escalator, li-skateboard, jj.); li-bushing tsa ho emisa likoloi; metsoako ea lipitsa tsa motlakase; likhomaretsi tse sebetsang hantle; liphahlo tsa bokaholimo le li-sealant tsa bokaholimo; likhoele tsa maiketsetso (mohlala, Spandex); k'hapete e ka tlas'a eona; likarolo tsa polasetiki e thata (mohlala, bakeng sa lisebelisoa tsa elektroniki).

Tšebeliso ea bohlokoa ea HTPB ke ho propellant e tiileng ea rokete. E tlama moemeli oa oxidizing, mafura le metsoako e meng hore e be boima bo tiileng empa bo tenyetsehang litsamaisong tse ngata tsa propellant tse kopaneng. Polyurethane e phekotsoeng e sebetsa e le mafura metswakong e joalo. Mohlala, propellant e le "HTPB/AP/Al=12/68/20", e bolelang, ka karolelano ea boima, HTPB hammoho le 12% ea phekolo (binder le mafura), ammonium perchlorate 68% (oxidizer), le phofo ea aluminium 20% (mafura).

Li-propellant tse tšoanang, tse atisang ho bitsoa APCP (ammonium perchlorate composite propellant) li sebelisoa liroketeng tse kholo tsa mohlala. APCP e tloaelehileng e hlahisa phallo e khethehileng ka makhetlo a 2-3 ea propellant ea phofo e ntšo e sebelisoang lienjeneng tse ngata tse nyane tsa rokete.

HTPB e boetse e sebelisoa e le mafura a rokete a kopantsoeng.

Thepa ea ts'ebetso ea HTPB e latela:

1. Ho se rate metsi

2. Lihlopha tsa hyroxyl tse arabelang

3. Mocheso o tlase oa phetoho ea khalase

4. 'Mala o tlase - mokelikeli o nang le viscous o hlakileng haholo

5. Ho hanyetsa hydrolysis

6. Khanyetso e tlase ea mocheso

7. Ho kenella ha mongobo o tlase

8. Ho hanyetsa li-acid le metheo ea metsi

9. Khanyetso e matla ea ho roala

10. Ho khomarela hantle haholo mefuta e fapaneng ea li-substrate

11. Thepa ea ho thibela mocheso oa motlakase
