Kukonza Kupanga kwa HTPB, CTBN ndi DDI (Dimeryl Diisocyanate)
Kodi ndi chiyani HTTPB ?
HTTPB amadziwikanso kuti polybutadiene yothetsedwa ndi hydroxyl (CAS No. 69102-90-5), ndi rabara yatsopano yamadzimadzi (resin), Ma HTPB ali ndi magulu a hyroxyl omwe amayankha. Imatha kuchitapo kanthu ndi chowonjezera cha unyolo, cholumikizira cholumikizira kutentha kwa chipinda kapena kutentha kwambiri kuti ipange kapangidwe ka netiweki ya 3D yokhala ndi zinthu zochiritsa zomwe zimakhala ndi mphamvu zabwino kwambiri zamakanika.
Makhalidwe a HTPB monga: Hydrophobicity, Magulu a hyroxyl okhudzidwa, Kutentha kochepa kwa kusintha kwa galasi, Mtundu wochepa - madzi okhuthala omveka bwino, Kukana hydrolysis,
Kukana kutentha kochepa, Kulowa chinyezi pang'ono, Kukana ma asidi amadzi ndi maziko, Kukana kutopa kwambiri, Kumamatira bwino kwambiri kuzinthu zosiyanasiyana, Kuteteza magetsi, Kukana kugwiritsa ntchito makina kwambiri mu:
- Zophimba
- Zomatira
- Zopangira mphamvu
- Zipangizo za Polyurethane (PU)
- Zomangira
- Zomatira
- Zipangizo zamagetsi zotetezera kutentha
- Zogulitsa za rabara
- Zipangizo zomangira m'magalimoto ndi ndege
- Zipangizo zomangira (zosalowa madzi, zoletsa dzimbiri, zoteteza kutentha)
- Kuyika m'miphika ndi kuyikamo
- Kusintha kwa Polima
- ndi mitundu ina yambiri yogwiritsira ntchito.
Kodi ndi chiyani CTBN ?
CTBN amadziwanso ngati Copolymer ya butadiene-acrylonitrile yothetsedwa ndi carboxyl ( CAS No. 25265-19-4 kapena 68891-46-3)Gulu la carboxyl, lomwe ndi gulu lake logwira ntchito, lingagwiritsidwe ntchito kwambiri m'mafakitale a ndege ndi mafakitale aboma. Chifukwa cha gulu logwira ntchito lomwe latha ntchito la carboxyl, limatha kuchitapo kanthu ndi epoxy resin kuti liwonjezere kulimba.
Makhalidwe a CTBN ndi awa: Amalimbitsa kulimba ndi kusinthasintha kwa ma resins a thermoset, Amalimbitsa kumamatira ku substrates zomwe zimakhala zovuta kumamatira, Amawonjezera kukana kugwedezeka ndi ming'alu, Amalimbitsa kulimba (kukana kutopa), Amawonjezera mphamvu zamakina zotentha kwambiri, ndi zina zotero. Izi zimapangitsa kuti zigwiritsidwe ntchito kwambiri mu:
1. Zomatira, zomangira, zotsekera, zopopera, zophikira m'miphika (mlengalenga, magalimoto, zamagetsi/zamagetsi, mafakitale, za m'madzi ndi zomangamanga..)
2. Zophimba (mankhwala, ufa, zoyendera m'madzi)
3. CTBN ndi kulimba kwa epoxy resin, komanso chosinthira chabwino kwambiri cha ma resin osinthira kutentha monga epoxy, phenolic, unsaturated polyester ndi ma resin osavuta kuwala.
Kodi ndi chiyani AYI ?
AYI amadziwanso ngati Dimeryl Diisocyanate CAS No. 68239-06-5, DDI ndi diisocyanate yapadera ya aliphatic yomwe ingagwiritsidwe ntchito kukonza ma polima okhala ndi mankhwala okhala ndi haidrojeni yogwira ntchito. Ndi chophatikiza cha unyolo wautali chokhala ndi msana wa mafuta a 36-carbon dimer. Kapangidwe ka unyolo waukulu kamapatsa DDI kusinthasintha kwapamwamba, kukana madzi komanso poizoni wochepa kwa ma isocyanate ena a aliphatic. DDI ndi madzi otsika kwambiri omwe amasungunuka mosavuta m'zosungunulira zambiri za polar kapena non-polar. Chifukwa ndi aliphatic isocyanate, ili ndi makhalidwe osachita chikasu. Ili ndi zabwino zambiri za poizoni wochepa, yosavuta kugwiritsa ntchito, yosungunuka m'zosungunulira zambiri, nthawi yowongolera yochitapo kanthu komanso kusakhala ndi mphamvu yamadzi. Ndi mtundu wamba wa isocyanate wapadera wobiriwira, womwe ungagwiritsidwe ntchito kwambiri pomaliza nsalu, ma elastomers, zomatira ndi zomatira, zokutira, inki ndi minda ina yankhondo ndi ya boma.
Takonza bwino kupanga HTPB, CTBN ndi DDI (Dimeryl Diisocyanate) kuti tiwongolere magwiridwe antchito awo, komanso kuti mitengo ikhale yopikisana kwambiri poyerekeza ndi Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
