E pili ana iā mākou

Ke hoʻomau nei mākou i ka hāʻawi ʻana i nā huahana alumina i ka mākeke honua, ʻo ia hoʻi ka hana ʻana i ka alumina kūikawā adsorbent no ka hydrogen peroxide, ka mea hoʻomaloʻo pōpō alumina i hoʻoulu ʻia, ka mea hana alumina defluoride i hoʻoulu ʻia, ka pōpō alumina potassium permanganate, ka mea lawe catalyst, ka sieve molekala. Loaʻa i ka ʻoihana ka ikaika ʻenehana ikaika, nā lako hana akamai, nā ʻenehana holomua, ka hoʻokele maikaʻi maʻamau, a me nā lawelawe loea kiʻekiʻe. Loaʻa i kēia moʻo o nā huahana ka density kūpono a me ka hoʻolaha nui o ka pore, ka density ʻāpana like, ka ikaika mechanical kiʻekiʻe, ʻaʻole maʻalahi ke pulverize, a he mau ʻano o ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa i ka erosion a me ka hana maikaʻi, hiki ke hoʻokō i nā koi like ʻole o nā ʻano like ʻole a me nā mea kūʻai aku like ʻole no nā huahana. ʻAʻole kūʻai maikaʻi wale kā mākou huahana ma ka ʻāina holoʻokoʻa akā loaʻa iā ia kahi kūlana kūʻai aku honua maikaʻi, e uhi ana ma mua o 40 mau ʻāina a me nā ʻāpana a puni ka honua, a ʻo mākou kekahi o nā kumu hana kemika koʻikoʻi loa.

Ua hilinaʻi mākou e hāʻawi iā ʻoe i nā huahana kūpono.
