No ke aha i makemake nui ʻia ai ʻo AH36, DH36, a me EH36 i ka ʻoihana moana

1. Ka lakio ikaika-i-kaumaha kiʻekiʻe loa

ʻO kekahi o nā pōmaikaʻi nui o kēia mau ʻano, ʻo ia ko lākouikaika kiʻekiʻe i hui pū ʻia me ke kaumaha i hoʻemi ʻia. ʻAe kēia i nā mea hana moku e hoʻolālā i nā ʻili māmā me ka ʻole o ka hoʻopilikia ʻana i ka palekana. ʻO ka hopenaka hoʻomaikaʻi ʻana i ka pono o ka wahie, ka nui o ka hiki ke ukana, a me ka hoʻemi ʻana i nā hoʻokuʻu ʻana, e kūlike ana me nā pahuhopu hoʻomau kai o kēia au.

2. ʻO ka paʻakikī haʻahaʻa haʻahaʻa maikaʻi loa

Pono nā moku e holo ana ma nā wahi anuanu a i ʻole nā ​​​​wai polar i nā mea e mālama i ka paʻa ma nā mahana ma lalo o ka zero. Hoʻāʻo ʻia ʻo DH36 a me EH36, ma ke ʻano kūikawā, no ke kūpaʻa ʻana i ka hopena ma-20°C a me -40°C, e hōʻoiaʻiʻo anaductility a me ke kūpaʻa i ka hakiʻoiai i nā wahi hau.

3. Ke kūpaʻa kū'ē i ka palaho

Hoʻolalelale ka wai paʻakai a me ka haʻahaʻa i ka pala, kahi e hiki ai ke hoʻopilikia i ke kūpaʻa o ka moku.

Nā ʻAno Hou i nā Hana Hana Kila Moana

Ke hoʻohālikelike ʻia nei ka wā e hiki mai ana o ke kūkulu moku a me ka ʻenekinia ma waho e nā holomua i lokonā mea māmā, mālama i ka ikehu, a me nā mea hoʻomau. I ka ulu ʻana o nā moku i ka nui a me ke kūikawā, ke koi ʻia neinā kila haʻahaʻa ikaika kiʻekiʻee like me AH36, DH36, a me EH36 e hoʻomau nei i ka piʻi ʻana.

ʻO nā noi e kū mai ana:

• Nā moku hoʻoneʻe hybride koi ana i nā mea ʻili i hoʻonui ʻia i ke kaumaha

• Nā kahua hana ʻeli a me ka ʻimi ʻana i ke kai hohonui kūkulu ʻia no nā kūlana hohonu loa

• Nā ʻenehana hoʻouna ʻōmaʻomaʻo, kahi e hōʻemi ai nā kila pale i ka palaho i ka mālama ʻana a me nā hoʻokuʻu ʻana

Hoʻomau ka hana hou ʻana i ka hana kila - e like meka ʻōwili thermo-mechanical a me ka microalloying— hōʻoiaʻiʻo e noho mau kēia mau māka ma ke alo o ka ʻenekinia moana no nā makahiki he nui e hiki mai ana.
