ʻO nāʻano mea kila kila: He alakaʻi kūpono

Hōʻikeʻike

Kila kohu ʻole he mea hoʻohana nuiʻia iʻikeʻia no kona mau waiwai kūʻokoʻa e like me ka durability, ikaika, a me ka paleʻana i ka corrosion.

Hoʻohanaʻia ia ma waena o nāʻoihana likeʻole, mai ka hanaʻana a me ka AutoMotouve i nā polokalamu lapaʻau a me nā mea hana kīhini kiʻekiʻe.

Ke kohoʻana i keʻano kūpono o keʻano o ka steelless steelless e hōʻoia i ka hana maikaʻi a me ka lōʻihi ma nā noi likeʻole. Hāʻawi kēia alakaʻi i kahiʻike hohonu i loko o nāʻanoʻano likeʻole o nāʻano kila maikaʻiʻole, kā lākouʻano, a me nā noi kūpono.

1. He aha ke kila stiinless?

ʻO ke kilataʻole he alloy i hana mua i ka hao a me ka liʻiliʻi loa 10.5% Chromium, Hāʻawi iā ia i ke kū'ē kū'ē kū'ē. Ka hoʻohuiʻana o ka chromium eʻae i ka hoʻokumuʻana o kahi'āpana, pale aku i ka mixidey i luna o ka papa kila, pale aku i ka palau a me ka oxidation.

Nā mea'ē aʻe e like me nickel, Mybrideum, A hoʻohuiʻia pahaʻo Manganese e hoʻonui i nā waiwai kiko'ī e like me ka ikaika, kumaikalua, a me ka paleʻana i ka wela a me nā mea kanu.

Nā waiwai maʻamau o nā kila kila:

• ‌Ke kū'ē neiʻo Corrosionion: ʻO ka mea chromium i loko o nā mea kila kila e like me ka oxygen e hana ai i kahi o ka sodin sodin chorum chromate, ka mea e hōʻemi pono ai i ka hopena o ka corrosio a hana i ke kila maikaʻiʻole i ka corrossion maikaʻi.
• ‌ʻO ke kū'ēʻana: Hiki i ke kila Strainless ke mālama i nā waiwai pilikino maikaʻi loa a me nā mea hana ma nā kiʻekiʻe kiʻekiʻe, He mea wela maikaʻi, a hiki ke mālama i nā waiwai pilikino maikaʻi a me ke kemika ma nā wahi likeʻole.
• Ikaika ikaika: He ikaika ikaikaʻo Stoiinless a me ka ikaika a hiki ke ikaika a me ke kaumaha.
• Palekana a me ka hygiene: ʻAʻole i loaʻa nā mea kila Strielless i nā mea radioactive aʻaʻole e hōʻeha i kekahi kino o ke kino. He kūpono ia no nā lako hana meaʻai a iʻole nā ​​laina hana a me nā mea hana'ē aʻe.
• Naniʻo nani: ʻO ke kapa o ka kila kila he mālamalama, maʻalahi e hoʻomaʻemaʻe, a he uku haʻahaʻa haʻahaʻa haʻahaʻa.
• ‌Palapala maikai: Hiki ke hanaʻiaʻo Stiinless Steel a ho'ōlaʻia i loko o nāʻano likeʻole, e like me ka welding, Ke kaʻina anuanu, Ka hana kūpono, etc.
• ‌Recycability: Hiki ke kiʻi houʻia nā mea kila kilati.
• ‌Elasticity maikaʻi a me ka momona: ʻO nā mea kila kila maikaʻiʻole i ka elasticity maikaʻi a me ka palupalu aʻaʻole i hōʻoiaʻia e wāwahi.

ʻO kēia mau hiʻohiʻona e hana nui ai i nā kila ākea i hoʻohana pinepineʻia ma nāʻano likeʻole, e like me ka mīkini, 'Anelelo, ʻOihanaʻoihana, Kālā Kauka, etc.

2. ʻO nāʻano mea kila kila

Ua māheleʻiaʻo Stiinless Steel i nāʻohanaʻelima, ʻO kēlā me kēia me nā micstructures likeʻole a me nā mea hoʻohālikelike e like me nā mea i hāʻawiʻia i nā waiwai kūʻokoʻa. ʻO ka hoʻomaopopoʻana i kēia mau papa inoa he mea nui no ke kohoʻana i nā mea kūpono no nā noi likeʻole, mai nā mea pāʻani kinikini i nā'āpana o Arospace. Eia kahi hohonu hohonu i kēlā me kēiaʻano:
