- HTTPBMa elastomer a polyurethane okhala ndi utoto amakhala osinthasintha komanso olimba ngakhale kutentha kochepa kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri m'malo ozizira.
- Ma elastomer awa amapereka kukana bwino kwa UV komanso kuyamwa madzi pang'ono, zomwe zimapangitsa kuti zinthu zikhale zolimba panja komanso m'malo ovuta.
- HTTPBKatundu wapadera wa kampaniyo amalola kugwiritsa ntchito zinthu zosiyanasiyana m'mafakitale monga ndege, magalimoto, ndi zamagetsi, zomwe zikuyendetsa kukula kwakukulu kwa msika.
Kugwiritsa ntchito HTPB (Hydroxyl-terminated polybutadiene CAS 69102-90-5) Mu Polyurethane Elastomers: N’chiyani Chimasiyanitsa
Tanthauzo ndi Kapangidwe ka HTTPB
Mungadabwe kuti n’chiyani chimapangitsa HTPB kukhala yapadera. HTPB imayimira hydroxyl-terminated polybutadiene. Zinthuzi zili ndi kapangidwe kake kapadera komwe kamapatsa zinthu zambiri zothandiza. Mumapeza magulu a hydroxyl kumapeto onse a molekyulu ya HTPB. Maguluwa amachitapo kanthu mwamphamvu ndi isocyanates, zomwe zimathandiza kupanga urethane bonds yolimba. Msana wa HTPB umapangidwa ndi mayunitsi osinthasintha a butadiene. Kapangidwe kameneka kamakupatsani zinthu zomwe zimakhala zofewa komanso zotambasuka, ngakhale nyengo yozizira.
- HTPB ili ndi kutentha kochepa kwa kusintha kwa galasi, nthawi zambiri pafupifupi -75°C mpaka -80°C.
- Molekyu imatha kutambasuka kwambiri isanasweke, ndipo nthawi zina imatambasuka ndi kutalika kwa 1000%.
- HTPB imakana madzi ndipo simatenga chinyezi chambiri, kotero imagwira ntchito bwino m'malo onyowa kapena ovuta.
Makhalidwe Aakulu mu Polyurethane Elastomers
Mukagwiritsa ntchito HTTPB Mu ma elastomer a polyurethane, mumapeza zabwino zingapo zofunika. Kugwiritsa ntchito HTPB mu ma elastomer a polyurethane kumakupatsani zinthu zomwe zimakhala zosinthasintha komanso zolimba m'mikhalidwe yambiri. Magulu a hydroxyl kumapeto kwa HTPB amachitapo kanthu mwachangu ndi isocyanates. Izi zimapangitsa kuti pakhale netiweki yolimba, yomwe imawonjezera kusinthasintha komanso mphamvu yokoka.
- HTPB yochiritsidwa imayamwa madzi ochepera 1% kulemera kwake. Izi zimathandiza kuteteza zinthu zomwe zimakhudzidwa ndi chinyezi.
- Mumapeza kukana bwino kwa UV, kotero zinthu zanu zimakhala nthawi yayitali panja.
- HTPB ikhoza kusinthidwa ndi mankhwala apadera, monga magulu okhala ndi triazine. Kusintha kumeneku kumatha kuwonjezera mphamvu komanso kuwonjezera zinthu zatsopano, monga photoluminescence.
| Zatsopano Zofunika | Kufotokozera |
|---|---|
| Magawo opangidwa ndi Triazine | Magulu awa kumapeto kwa HTPB amalimbitsa mphamvu ndi kukhazikika kudzera mu mphamvu zamphamvu zamagetsi. |
| Kuwala kwa dzuwa | Kusintha kwa mankhwala kungapangitse HTPB kuwala ndikusintha mawonekedwe ake a makina. |
Mukuwona momwe ntchito ya HTTPB mu polyurethane elastomers m'magawo ambiri. Imagwira ntchito ngati chomangira mu ma rocket propellants, chotchinga chinyezi mu ma encapsulants, komanso maziko a zinthu zolimba komanso zosinthasintha. Zinthu izi zimapangitsa HTPB kukhala chisankho chabwino kwambiri pakugwiritsa ntchito molimbika.
HTTPB vs. Ma Polyol Ena mu Polyurethane Elastomers
Kuyerekeza kwa Katundu wa Makina ndi Mankhwala
Mukayerekeza HTPB (Hydroxyl-terminated polybutadiene CAS 69102-90-5) Kwa ma polyol ena, mumawona kusiyana kwakukulu momwe amagwirira ntchito. HTPB imakupatsani kutentha kochepa kwa kusintha kwa galasi, zomwe zikutanthauza kuti ma elastomer anu amakhala osinthasintha ngakhale munyengo yozizira kwambiri. Ma polyol ena nthawi zambiri amakhala ndi kutentha kwakukulu kwa kusintha kwa galasi, kotero amatha kuuma kapena kusweka akayamba kuzizira.
Mukuonanso zimenezo HTTPBMa elastomer okhala ndi ma elastomer ali ndi kukanikiza bwino komanso kukana mankhwala. Mwachitsanzo, HTPB imapeza 5B pa mayeso a kukanikiza a ASTM D3359, omwe ndi okwera kuposa ma polyol ena ambiri. Izi zikutanthauza kuti zokutira zanu kapena zomatira zimamatira bwino komanso zimakhala nthawi yayitali. HTPB imakana kutupa mu mafuta monga JP-8, ndi kutupa kosakwana 10%, pomwe ma polyol ena amatha kutupa kwambiri ndikutaya mawonekedwe awo.
Nayi tebulo lomwe likuwonetsa momwe HTTPB poyerekeza ndi ma polyol ena:
| Benchmark | HTTPB Magwiridwe antchito | Kuyerekeza ndi Ma Polyol Ena |
|---|---|---|
| Kutentha kwa Galasi | Tg Yotsika (-75°C) | Zimasiyana pakati pa ma polyol ena |
| Ma Ratings a Kumatira | 5B pa ASTM D3359 | Kawirikawiri otsika kwa ma polyol ena |
| Kukana Mankhwala | Kuchuluka kwa mafuta a JP-8 m'munsi mwa 10% | Nthawi zambiri kuchuluka kwa kutupa kumakwera |
| Kulimba | >90% kusungidwa kwa gloss pambuyo pa maola 1,000 | Kawirikawiri sizilimba |
Mumapezanso maubwino ambiri ndi HTTPBSizimayamwa madzi ambiri, choncho zimagwira ntchito bwino m'malo onyowa. Zimalimbananso ndi ma acid ndi ma bases, ndipo zimakhala ndi mphamvu ya dielectric. Zinthu zimenezi zimapangitsa HTPB kukhala chisankho chanzeru pantchito zovuta.
Langizo: Ngati mukufuna chinthu chomwe chimasinthasintha kuzizira komanso chimalimbana ndi mankhwala, HTTPBMa elastomer a polyurethane okhala ndi utoto ndi njira yabwino kwambiri.
Kugwira Ntchito mu Ntchito za Elastomer
Mukufuna kuti ma elastomer anu agwire ntchito bwino nthawi zambiri. HTTPBMa elastomer a polyurethane okhala ndi utoto amakupatsani mphamvu yabwino kwambiri kutentha pang'ono. Amakhala ofewa komanso osinthasintha pa -75°C, pomwe makina ena okhala ndi utoto wa polyol amatha kukhala olimba kapena osweka.
Nayi njira yodziwira momwe zinthu zilili HTTPB poyerekeza ndi ma polyol ena pa kutentha kochepa:
| Katundu | Polyurethane yochokera ku HTPB | Machitidwe Ena Ochokera ku Polyol |

| Kusinthasintha pa Kutentha Kotsika | Zabwino kwambiri | Zochepa |
Mumapezanso kulimba kwambiri ndi HTTPB. Zogulitsa zanu zimasunga kuwala kwawo ndipo sizimawonongeka mosavuta, ngakhale zitagwiritsidwa ntchito kwa nthawi yayitali. Ma elastomer okhala ndi HTPB amagwira ntchito bwino mu zokutira, zomatira, ndi zotsekera. Amateteza ku madzi, mchere, ndi mankhwala oopsa. Izi zimapangitsa kuti azidziwika kwambiri pa ntchito zapamadzi, zankhondo, komanso zakunja.
HTPB imawonetsa kusagwirizana ndi madzi, zomwe zikutanthauza kuti imathamangitsa madzi. Ilinso ndi mphamvu zabwino kwambiri zotsutsana ndi asidi komanso mphamvu zamphamvu za dielectric. Zinthuzi zimathandiza kuti zinthu zanu zikhale nthawi yayitali komanso kuti zigwire bwino ntchito.
Kusiyana kwa Mtengo ndi Kukonza
Mukayang'ana mtengo ndi kukonza kwa HTTPBMa elastomer a polyurethane okhala ndi utoto, mumapeza zabwino komanso zovuta zonse. HTPB imakupatsani mwayi wosavuta kukonza chifukwa imagwira ntchito bwino ndi ma isocyanate monga HDI. Izi zimapanga mafilimu olimba omwe amakana chinyezi ndi mchere. Mutha kugwiritsa ntchito HTPB m'malo osiyanasiyana, kuphatikizapo malo ankhondo ndi m'madzi.
Mukhozanso kusintha mphamvu ya HTTPBMa polyurethane okhala ndi ma crosslinker posintha crosslinker. Mwachitsanzo, kugwiritsa ntchito boron trifluoride triethanolamine complex ngati crosslinker kumapangitsa elastomer yanu kukhala yolimba. Ngati muwonjezera crosslinker yambiri, mumapeza mphamvu zambiri. Kusinthasintha kumeneku kumakupatsani mwayi wopanga zipangizo zomwe zikugwirizana ndi zosowa zambiri.
Komabe, mungakumane ndi mavuto ena. HTTPB Opanga ayenera kutsatira malamulo okhwima okhudza chilengedwe, makamaka okhudza kutulutsa mpweya wa VOC. Malamulowa awonjezera ndalama ndi 25% pazaka zitatu zapitazi. HTPB simalimbananso ndi kutentha kwambiri komanso ma elastomer ena atsopano. Pa kutentha kopitilira 150°C, HTPB imatha kusweka ndi 30% mwachangu kuposa zipangizo zina.
Nayi tebulo lomwe likuwonetsa mavuto omwe amakumana nawo nthawi zambiri:
