He aha nā kumu o ka ʻeleʻele o ka ʻili alumini alumini?

Nui nā kumu no ka ʻeleʻele ʻana o nā ʻili alumini alumini, ʻo ia kekahi:

1. Oxidation: Hōʻike ʻia ka alumini i ka ea a hana me ka oxygen e hana i kahi papa o ka alumini oxide ma ka ʻili.He mea maʻa mau kēia ʻāpana oxide a pale i ka alumini mai ka ʻino hou aʻe.Eia nō naʻe, inā pilikia a ʻino paha ka papa o ka oxide, hōʻike ia i ka alumini i lalo i ka ea a hiki ke hoʻoulu hou i ka oxidation, e hopena i kahi hiʻohiʻona ʻeleʻele a ʻeleʻele paha.

2. Ka hopena kemika: Hiki i ka ʻike ʻana i kekahi mau mea kemika a ʻeleʻele paha ka ʻili alumini.No ka laʻana, hiki i ka ʻike ʻana i nā ʻakika, nā ʻoluʻolu alkaline, a i ʻole nā ​​paʻakai ke kumu i ka hopena kemika e hiki ai ke hoʻopōʻeleʻele.

3. Hoʻomaʻamaʻa wela: Hoʻokomo pinepineʻia nā'āpana alumini i nā kaʻina hana wela e hoʻonui i ko lākou ikaika a me ka paʻakikī.Eia nō naʻe, inā ʻaʻole mālama pono ʻia ka mahana a i ʻole ka manawa o ka mālama ʻana i ka wela, e hoʻoneʻe a ʻeleʻele paha ka ʻili.

4. Hoʻohaumia: ʻO ka loaʻa ʻana o nā mea haumia ma luna o ka ʻili o nā alumini alumini, e like me ka ʻaila, ka momona a i ʻole nā ​​​​mea haumia ʻē aʻe, e hoʻoneʻe a ʻeleʻele paha ma muli o nā hopena kemika a i ʻole ka launa pū ʻana.

5. Anodizing: ʻO ka Anodizing kahi kaʻina hana lapaʻau e pili ana i ka mālama electrochemical o ka alumini e hana i kahi papa o ka oxide ma ka ʻili.Hiki ke hoʻoluʻu ʻia a ʻulaʻula ʻia paha kēia ʻāpana oxide e hana i nā ʻano hoʻopau like ʻole, me ka ʻeleʻele.Eia nō naʻe, inā ʻaʻole i mālama pono ʻia ke kaʻina hana anodizing a maikaʻi ʻole paha nā kala a i ʻole nā ​​kala kala, hiki ke hopena i ka hoʻopau ʻole ʻana a i ʻole ka wehe ʻana.
