Pehea e pale aku ai i ka pala mai na kui hao

ʻO ke kumumanaʻo o nā kui hao hao.

ʻO ka hoʻoheheʻe ʻana he hopena kemika, ke waiho ʻia ka hao no ka manawa lōʻihi e ʻōpala. He maʻalahi ka hao, ʻaʻole wale no kona ʻano kemika ikaika, akā no nā kūlana o waho. ʻO ka makū kekahi o nā mea e maʻalahi ai ka hao.

Akā naʻe, ʻaʻole e hana ka wai wale i ka ʻele hao. Ke hoʻoheheʻe ʻia ka oxygen i ka lewa i loko o ka wai, hana ka oxygen me ka hao i loko o ke kaiapuni me ka wai e hoʻohua i kahi mea hao hao, ʻo ia ka ʻōpala.

ʻO ka ʻōpala he mea ʻulaʻula ʻulaʻula ʻaʻole paʻakikī e like me ka hao a hiki ke hoʻokahe maʻalahi. Ke ʻeleʻele loa ka ʻāpana hao, hiki ke hoʻonui ka leo i 8 manawa. Inā ʻaʻole wehe ʻia ka ʻōpala, ʻoi aku ka maʻalahi o ka ʻōpala spongy i ka hoʻomoʻa ʻana i ka makū, a ʻoi aku ka wikiwiki o ka hao. E ʻoi aku ke kaumaha o ka hao i ka wā e ʻele ai, ma kahi o 3 a 5 paha manawa o kona kaumaha kumu.

ʻO nā kui hao ka mea maʻamau i ko mākou ola i kēlā me kēia lā nā kui, ʻo ia hoʻi ka laulā nui o nā noi, akā he maʻalahi nā kui hao i ka maʻalahi, e haʻi wau iā ʻoe i nā ʻano e pale ai i ka pala o nā kui hao.

ʻO ke ʻano o ka pale ʻana i nā kui mai ka ʻōpala ʻana ke ʻano penei:

1, ka haku mele 'ana e ho'ololi i ka hale o loko o ka hao. No ka laʻana, chromium, nickel a me nā metala ʻē aʻe i hoʻohui ʻia i ke kila maʻamau i hana ʻia me ke kila kila, hoʻonui nui i ka pale ʻana o nā huahana kila.

2、ʻO ka uhi ʻana i ka ʻili o nā huahana hao me kahi pale pale kahi ala maʻamau a koʻikoʻi e pale ai i nā huahana hao mai ka pala. Ma muli o ke ʻano o ka papa pale, hiki ke hoʻokaʻawale ʻia i nā ʻāpana:

a. Ka uhi ʻana i ka ʻili o nā huahana hao me ka ʻaila mineral, pena a i ʻole ke ahi ahi, ka pīpī ʻana i ka plastic, etc.

b. Ke kau nei ma luna o ka ili o ka hao a me ke kila me ka electroplating, ka wela wela a me nā ʻano hana ʻē aʻe, e like me ka zinc, tin, chromium, nickel a me nā mea ʻē aʻe, kahi ʻāpana o ka metala pale. Hiki i kēia mau metala ke hana i kahi kiʻiʻoniʻoni oxide nui ma luna o ka ʻili, no laila e pale ai i nā huahana hao mai ka ʻānae ʻana me ka wai, ka ea a me nā mea ʻē aʻe.

c. Hana kemika i ka ʻili o nā huahana hao e hoʻohua i kahi ʻano kiʻiʻoniʻoni oxide paʻa a paʻa i mea e pale ai i nā huahana hao mai ka pala.

3、ʻO ka mālama ʻana i ka maʻemaʻe a me ka maloʻo o ka ʻili o nā mea hao he ala maikaʻi ia e pale aku ai i nā huahana hao mai ka pala.
