HTPB: Kukonza Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa

Chomangira mu Zopangira Zolimba za Rocket

Mumadalira HTPB: Kukonza Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa ndi Impact pamene mukufuna chomangira cha ma propellant olimba a roketi. Zinthuzi zimakulolani kuyika tinthu tambiri tolimba, monga ammonium perchlorate ndi aluminiyamu, mu propellant—mpaka 90% polemera. Mumapeza propellant yolimba komanso yosinthasintha. HTPB imakupatsani kukanikiza bwino kwambiri kuzinthu zosiyanasiyana, zomwe zimathandiza ma roketi anu kugwira ntchito bwino komanso kukhala nthawi yayitali. Mumapindulanso ndi kutentha kwake kwakukulu komanso kukana ukalamba, okosijeni, ndi hydrolysis.

• HTPB imalola kuti pakhale magawo olimba kwambiri (okwana 88–90% ya AP ndi Al).
• Imakhala ndi makhalidwe abwino akuthupi.
• HTPB imakondedwa chifukwa cha mphamvu zake zamakanika komanso kumamatira bwino kuzinthu zosiyanasiyana.
• Ndi yolimba ku ukalamba ndipo ili ndi kukhazikika kwakukulu kwa okosijeni ndi hydrolytic.
• HTPB ndiye chomangira chomwe chimagwiritsidwa ntchito kwambiri mu ma composite propellant formulations.

• Ili ndi kutentha kwakukulu kwa moto.

Mutha kuwona momwe HTPB: Kuwongolera Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa kumafananira ndi ma polima ena mu tebulo ili m'munsimu:

HTPB: Kuwongolera Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa Kumawonekera bwino chifukwa kumakupatsani kusinthasintha, mphamvu, komanso kugwirizana ndi zigawo zina za propellant.

Zotetezera ndi Zinthu Zopangira Liner

Mumagwiritsa ntchito HTPB: Kupititsa patsogolo Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa ndi Impact ngati chinthu choteteza ndi choteteza m'mlengalenga. Zinthuzi zimakuthandizani kupanga mgwirizano wolimba pakati pa choteteza ndi choteteza. Mutha kusintha chiŵerengero cha isocyanate-to-hydroxyl kuti muwongolere mgwirizano ndikupewa mavuto a chinyezi. Mukagwiritsa ntchito HTPB yokhala ndi zowonjezera zapadera, mumapeza mgwirizano wabwino pakati pa tinthu ta binder ndi filler. Njirayi imakuthandizani kupewa ma voids ndi malo ofooka mu choteteza chanu.

Kapangidwe ka liner kamagwiritsa ntchito chiŵerengero cha isocyanate-to-hydroxyl (NCO/OH) choposa 1 pang'ono kuti chithandizire chinyezi chomwe chikuyamba. Komabe, chofunika kwambiri, chiŵerengerochi chimalola kuti cholumikizira cha R-45M propellant chifike ku magulu a isocyanate osakhudzidwa, motero kuwonjezera mphamvu zomangira pa interface iyi. Chifukwa chake, kuchira kwa liner pa ma ratios awa sikuyenera kuloledwa kupitirira mpaka pomwe kulumikizana mu liner kumasokoneza kufalikira kwa zigawo za cholumikizira cha propellant.

HX-752 imagwira ntchito ndi ammonium perchlorate oxidizer, zomwe zimathandiza kuti pakhale mgwirizano wabwino pakati pa HTPB ndi tinthu ta filler, ndipo imachotsa void formation yomwe ingachitike popanda.

Mumapeza chotenthetsera chomwe chili cholimba, chosinthasintha, komanso chodalirika pa malo okwera ndege ovuta.

Matrix Resin ya Zopangira Zapamwamba

Mumasankha HTPB: Kukonza Kusinthasintha kwa Zinthu ndi Kukana Kukhudzidwa ngati utomoni wa matrix pamene mukufuna zinthu zamakono zopangidwira ndege.
