He aha ka Diatomite?

ʻO ka Diatomite kahi pōhaku sedimentary siliceous biogenic i haku ʻia me nā koena fossilized o nā diatoms kahiko, nona nā waiwai e like me ke porosity kiʻekiʻe, adsorption, a me ka kānana. ʻO ka ʻāpana nui o ka diatomite he amorphous silicon dioxide (SiO₂), maʻamau ka helu ʻana ma mua o 80% a hiki i ka 94%, ʻoiai he mau mea haumia liʻiliʻi e like me Al₂O₃, Fe₂O₃, CaO, MgO, a me nā mea organik. ʻO nā waiwai kino a me nā kemika kū hoʻokahi o ka Diatomite ua hoʻolilo iā ia i mea pono ʻole i nā ʻoihana like ʻole ma ka honua holoʻokoʻa, me nā noi e pili ana i ke ola o kēlā me kēia lā, ka hana ʻoihana, a me ka palekana o ke kaiapuni.

1. Ke Kūkulu ʻia ʻana o Diatomite: He Hana Mana Geological i Hoʻohālikelike ʻia e ke Ola Kahiko a me ka Manawa

ʻO ka ʻāpana nui o ka diatomite nā paia cell siliceous (frustules) o nā diatoms kahiko—nā limu microscopic i noho i nā moana, nā loko, a me nā kino wai ʻē aʻe. I ko lākou ola ʻana, ua unuhi kēia mau meaola i ka silica i hoʻoheheʻe ʻia mai ka wai e kūkulu i ko lākou mau paia cell paʻakikī a porous. I ka make ʻana o nā diatoms, ua noho ko lākou mau iwi silica ma lalo o nā kino wai, e hōʻiliʻili ana i nā nui he nui. Ma lalo o ke ʻano mahana, kaomi, a me nā kūlana geological i nā miliona o nā makahiki, ua hana ʻia kēia mau waihona i ka compaction a me ka diagenesis, e hoʻololi ana i ka pōhaku palupalu, e like me ka chalk a mākou e kapa nei he diatomite. I loko o kēia kaʻina hana, ua mālama ʻia ke ʻano porous paʻakikī o nā diatom frustules, no laila e kau ana i ke kahua no nā waiwai kūikawā o ka diatomite.

I kēia lā, ua hoʻolaha ʻia nā waihona diatomite kiʻekiʻe ma ka honua holoʻokoʻa. ʻO nā wahi hana nui e komo pū ana me ʻAmelika Hui Pū ʻIa, Kina, Denemaka, Iapana, Palani, a me Mekiko. ʻO Kina ka lua o ka honua ma nā waihona diatomite, me nā waihona nui ma ka Hikina ʻĀkau o Kina (Jilin Changbai Mountain), Xinle (Hebei), nā ʻāina hikina, Panxi (Sichuan), a me ka hikina a me ke komohana hema o Yunnan. ʻOkoʻa kēia mau waihona i ka haku mele a me nā ʻano hana (i hoʻokaʻawale ʻia he diatomite maka hina, diatomite calcined melemele, a me ka diatomite flux-calcined keʻokeʻo), akā mālama lākou a pau i nā ʻano koʻikoʻi o ka diatomite—ka porosity maikaʻi loa a me ka hiki ke adsorption i loaʻa mai ka ʻano paʻakikī o nā diatoms fossilized.

2. Nā ʻAno Koʻikoʻi o ka Diatomite: No ke aha he mea kupaianaha loa ia?

ʻO ka hana kiʻekiʻe o ka diatomite mai ke ʻano microstructure kū hoʻokahi a me ka hoʻohui kemika o nā diatoms fossilized.

Porosity Kiʻekiʻe a me ka ʻĀpana ʻIli Nui: Loaʻa i ka Diatomite kahi ʻano porous paʻakikī me ka porosity e hiki ana i ka 90%, e hāʻawi ana i kahi ʻili ākea kikoʻī. Hiki i kēia ke hiki ke hoʻopili ʻia a me ka pono kānana no ka wehe ʻana i nā ʻāpana liʻiliʻi a me nā haumia.

Ka Mana HoʻopiliʻO ke ʻano porous microscopic o nā frustules diatom e hana i nā kahawai liʻiliʻi he nui ʻole e hiki ke hoʻopili ikaika i nā wai, nā kinoea, nā mea olaola, a me nā mea paʻa i hoʻokuʻu ʻia, me ka mālama pono ʻana i ka makū a me nā meaola.

Paʻa KemikaHe paʻa kemika ka Diatomite, kūpaʻa i nā waikawa (koe wale nō ka waikawa hydrofluoric), ʻaʻohe mea ʻawahia, ʻaʻohe ala, a aloha i ke kaiapuni. ʻAʻole ia e pane koke me ka hapa nui o nā mea, e hōʻoiaʻiʻo ana i ka palekana a me ka hilinaʻi i nā noi like ʻole e like me ka meaʻai a me nā lāʻau lapaʻau.

Ka Paʻa Haʻahaʻa a me ka Palena WelaHe māmā loa ka Diatomite (ka nui o ka nui 0.3-0.5 g/cm³) me ka conductivity thermal haʻahaʻa, e lilo ia i mea hoʻokaʻawale maikaʻi loa no nā noi wela kiʻekiʻe.

Ka Permeability a me ka kānanaʻO ka hoʻokaʻawale like ʻana o ka nui o nā pore e ʻae ai i ka kaohi kānana pololei, me nā māka like ʻole (300# a 1000#) i loaʻa no nā koi kānana like ʻole mai ka coarse a i ka fine.

Ke kū'ē ʻana i ka abrasionʻOiai kona māmā, he paʻakikī waena ko ka diatomite kūpono no ka hoʻopili ʻana me ka ʻole o ke kahakaha ʻana i nā ʻili.

Hana like kēia mau waiwai, e hoʻolilo ana i ka diatomite i mea i hoʻohana nui ʻia. Hiki ke hoʻohana ʻia ma ke ʻano he mea kōkua kānana, adsorbent, filler, carrier, a i ʻole insulating material e hoʻokō ai i nā pono hana like ʻole o nā ʻoihana like ʻole.

He ākea nā noi o ka Diatomite a ua hoʻohui nui ʻia i nā ʻāpana āpau o ka hoʻokele waiwai o ka ʻāina, e pāʻani ana i kahi kuleana koʻikoʻi i ka ʻoihana, ka palekana o ke kaiapuni, a me ka nohona o kānaka.
