The Long March 2F Rocket yonyamula Shenzhou-12 Manned Spacecraft idakhazikitsidwa bwino kuchokera ku Satellite Launch Center ku Jiuquan nthawi ya 9:22 am pa June 17, zomwe zikutanthauza kuti makampani opanga zakuthambo ku China apanga chitukuko china. chothandizira chodabwitsa pakukhazikitsa Shenzhen-12 ?

1.Rocket Gas Chiwongolero

Tungsten molybdenum alloy material ndiye chisankho chabwino kwambiri pa chiwongolero cha gasi wa injini ya rocket, chifukwa chiwongolero cha gasi wa injini ya rocket chimagwira ntchito potentha kwambiri komanso kutentha kwamphamvu.

Tungsten ndi molybdenum ndizomwe zili pakati pa thupi ndipo zokhazikika za lattice zimakhala pafupi wina ndi mzake, kotero zimatha kusakanikirana ndi m'malo mwa alloy ya binary. Poyerekeza ndi tungsten yoyera ndi molybdenum yoyera, tungsten molybdenum alloy ntchito zonse ndi bwino, makamaka mtengo kupanga ndi mphamvu mkulu kutentha.

2.Rocket Ignition Tube

Tungsten alloy zinthu ndizoyeneranso kuyatsa injini ya rocket. Chifukwa chake ndikuti kutentha kwa rocket kumapitilira 3000.℃zomwe zimatha kusungunula chitsulo, ndi aloyi ya tungstenUbwino wa 's ndendende ndi kukana kutentha kwambiri, kukana kwa dzimbiri, mphamvu yayikulu komanso kukana kwabwino kwa ablation.

3.Rocket Throat Bushing

Rocket bushing, gawo la injini, machitidwe ake amatha kukhudza kwambiri khalidwe la booster.the gasi pamene roketi imayambitsidwa pammero imatha kutulutsa mphamvu zambiri, zomwe zimapangitsa kutentha kwambiri komanso kupanikizika pakhosi. kwa kumero kwamasiku ano, chifukwa aloyi ya W-Cu imatha kupirira kutentha kwambiri komanso mphamvu yamakina.

Kupatula magawo omwe ali pamwambapa a roketi, palinso magawo ambiri opangidwa kuchokera ku tungsten ndi molybdenum materials.Ichi ndichifukwa chake tungsten ndi molybdenum zida zimathandizira modabwitsa pakukhazikitsa Shenzhen-12.
