CAS 69102-90-5 HTPB propellant e tiileng ea Hydroxyl-terminated polybutadiene HTPB bakeng sa propellant, sekhomaretsi, sealant
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Lintlha tsa sehlahisoa:
Lebitso la lik'hemik'hale: Hydroxyl-terinated polybutadiene
Khoutu: HTPB, HTPB-R45M
CAS: 69102-90-5
Sebopeho: China Authorized Exporter / HTPB laesense ea kantle ho naha
Maemo: GB (Mophato oa Sechaba) / GJB (Kereiti ea Sesole/ GJB 1327A-2003)
HTPB ke "remote" claw polymer, rabara e ncha ea metsi.Thepa e fapana hobane HTPB ke motsoako eseng motsoako o hloekileng, 'me o etsoa ho fihlela litlhoko tse khethehileng tsa bareki.HTPB e tlwaelehileng ke R-45M mme pheletso ka nngwe ya ketane e fediswa ka sehlopha sa hydroxyl [OH].
Eona le ketane ea katoloso ea moemeli, crosslinking moemeli ka mocheso oa kamore kapa karabelo e phahameng ea mocheso o ka hlahisa sebopeho sa marang-rang sa 3D sa ho folisa content.The folisa content e na le thepa e babatsehang ea mechine, haholo-holo ho hanyetsa hydrolysis, acid le alkali manganga, ho hanyetsa ho apara, ho hanyetsa mocheso o tlase le insulation e ntle haholo ea motlakase.
Polyurethanes e lokisitsoeng ho tloha HTPB e ka etsoa bakeng sa thepa e khethehileng ea 'mele;polyurethanes e ka 'na ea e-ba e tsitsitseng haholo kapa e thata le e thata.Lihlahisoa tse ling li kenyelletsa: liphanele tse thata tsa ho kenya foam;mabili a elastomeric a tšoarellang le lithaere (tse sebelisoang bakeng sa li-roller coasters, escalators, skateboards, joalo-joalo);lihlahla tse emisitsoeng tsa likoloi;metsoako ea lipitsa tsa motlakase;li-adhesives tse sebetsang hantle;ho roala ka holim'a metsi le li-sealants tse holim'a metsi;likhoele tsa maiketsetso (mohlala, Spandex);mokhabiso o ka tlas'a k'hapete;likarolo tsa polasetiki tse thata (mohlala, bakeng sa lisebelisoa tsa elektroniki).
Ts'ebeliso ea bohlokoa ea HTPB e ho propellant e tiileng ea rocket.E tlamella sesebediswa sa oxidizing, mafura le metsoako e meng hore e be boima bo tiileng empa bo rekere mefuteng e mengata ea li-propellant system.Polyurethane e phekotsoeng e sebetsa e le mafura ka har'a metsoako e joalo.Ka mohlala, propellant e le "HTPB/AP/Al=12/68/20", e bolelang, e lekantsoeng ka boima, HTPB le pholiso ea 12% (setlamo le mafura), ammonium perchlorate 68% (oxidizer), le phofo ea aluminium 20%. (mafura).
Li-propellant tse tšoanang, tseo hangata li bitsoang APCP (ammonium perchlorate composite propellant) li sebelisoa liroketeng tse kholoanyane tsa mohlala.APCP e tloaelehileng e hlahisa makhetlo a 2-3 ho feta tšusumetso e khethehileng ea phofo e ntšo e sebelisoang ho li-motor tse nyane haholo.
HTPB e boetse e sebelisoa e le mafura a rocket a hybrid.
HTPB e na le diaphaneity e ntle, viscosity e tlase, khanyetso ea botsofali, ts'ebetso e tlase ea mocheso, Hydrolysis resistance, acid le alkali resistance, wear resistance le thepa e babatsehang ea ho pata motlakase.
mme ts'ebetso ea ts'ebetso e ntle.HTPB e ka sebelisoa ho:
- Sekgomaretsi
- Li-sealents
- Li-polymers
- Lisebelisoa tsa ho kenya motlakase
- Lisebelisoa tsa ho thibela metsi le ho senya
- Ho roala
- Lisebelisoa tsa polyurethane
- Lihlahisoa tsa rabara
- Mafura a tiileng
- Propellant
- Lithaere tsa Koloi le Lifofane tsa thepa ea meralo
- Hydroxyl-terinated polybutadiene propellant(HTPB+AP+Al)
- Sepakapaka, Lirokete le Missile
- joalo-joalo mefuta e mengata ea tšebeliso.
Ho paka:
E pakiloeng ka 50kg/drum, 170kg/drum, Nako ea polokelo ke selemo se le seng.
Litaelo tsa polokeho:
Polokelo e lokela ho ba sebakeng se pholileng, se omeletseng le se nang le ventilate.Boemo bo botle ka ho fetisisa bo har'a -20 ~ 38 ℃.Shelofo ea nako ea likhoeli tse 12, haeba e felloa ke nako, e ntse e sebelisoa haeba e le maemong a ho hlahlojoa hape.Ha lipalangoang li lokela ho qoba pula, khanya ea letsatsi.Se ke oa kopanya le oxidizer e matla.
