Hoʻohana nui ʻia ʻo Aluminium i nā ʻoihana like ʻole ma muli o kona māmā, paʻa, a me ke kūpaʻa maikaʻi loa. Eia naʻe, ʻaʻole pale loa ia i ka ʻino. Ma kēia ʻatikala, e kūkākūkā mākou i ke ʻano o ka corrosion e pili ana iā ia, a me nā ala e pale ai i ka corrosion.

No ke aha ka ino o ka Aluminum Corrosion?

Makemake ʻia ka alumini ma nā noi like ʻole ma muli o kona haʻahaʻa haʻahaʻa, ʻoi aku ka māmā ma mua o nā metala ʻē aʻe e like me ke kila. Ua ʻike ʻia no kona maikaʻi maikaʻi o ka wela a me ka conductivity uila. Eia nō naʻe, hiki ke maʻalahi i nā ʻano ʻino like ʻole, e like me ka pitting, galvanic, a me ka corrosion inter-granular. Hana ʻia ka ʻinoʻino i ka wā e puka mai ai nā lua liʻiliʻi ma ka ʻili o ka metala ma muli o ka ʻike ʻana i nā kaiapuni koʻikoʻi. Hiki ke ʻinoʻino Galvanic ke hoʻopili ʻia ka alumini me nā metala like ʻole i mua o kahi electrolyte, e hana ana i kahi cell corrosion. Hoʻopilikia ka corrosion inter-granular i nā alumini alumini, hoʻonāwaliwali i ka mea ma nā palena o ka palaoa.

Nā ʻōlelo aʻoaʻo no ka pale ʻana i ka ʻinoʻino

No ka pale ʻana i ka corrosion alumini, ʻoi aku ka maikaʻi o nā pale pale.Anodizing, pena, a me ka paudae hāʻawi i kahi pale ma waena o ka metala a me kona ʻano ʻino, e pale ana i ka makū a me nā mea ʻino ʻē aʻe mai ka hiki ʻana i ka ʻili. Hiki i ka hoʻomaʻemaʻe maʻamau me ka kopa maʻemaʻe a me ka wai hiki ke wehe i ka lepo i hōʻiliʻili ʻia a me ka lepo, e pale aku i ka wikiwiki o ka corrosion. Pono e ʻalo ʻia nā kemika paʻakikī a me nā mea hoʻomaʻemaʻe abrasive no ka mea hiki iā lākou ke hōʻino i ka papa pale.

ʻO ka pale ʻana i ka alumini mai ka hoʻopili pololei ʻana me nā metala like ʻole e hōʻemi i ka pilikia o ka ʻino galvanic. Hiki ke hoʻohana ʻia nā mea insulating e like me ka plastic a i ʻole nā ​​pahu pahu e pale aku i ka pilina pololei ma waena o ka alumini a me nā metala ʻē aʻe. Eia kekahi, he mea koʻikoʻi ka mālama ʻana i ka ʻike ʻana i nā kaiapuni corrosive. ʻO ka hoʻokō ʻana i nā ʻano hoʻokalakupua kūpono a me ka hoʻokele haʻahaʻa hiki ke hōʻemi i ka pae o ka makū a me ka loaʻa ʻana o nā kemika corrosive a i ʻole ke kinoea.

I ka hopena, ʻoiai he nui nā pōmaikaʻi o ka alumini, hiki ke maʻalahi i ka corrosion. Pitting, galvanic, a inter-granular corrosion nā ʻano maʻamau e pili ana i ka alumini. ʻO ka hoʻohana ʻana i nā pale pale, ka mālama ʻana i ka maʻemaʻe, ka pale ʻana i ka pili ʻana me nā metala like ʻole, a me ka mālama ʻana i ka ʻike ʻana i nā kaiapuni corrosive ʻo ia nā ala pale pono. Ma ka hoʻokō ʻana i kēia mau ana, hiki ke hoʻonui ʻia ke ola a me ka hana o ka alumini, e hōʻoiaʻiʻo ana i kona hoʻohana mau ʻana i nā noi like ʻole.

Inā he mau nīnau hou aʻe kāu e pili ana i ka pale ʻana i ka ʻino alumini, e ʻoluʻolu ekāhea iā mā˚oue aʻo hou aku. ʻOi aku ka maikaʻi o ka pale ʻana ma mua o ka hoʻopaʻa ʻana i ka corrosion i ka wā e komo ai.
