ʻO ka honua Diatomaceous kahi ʻano pōhaku siliceous i hoʻolaha nui ʻia ma nā ʻāina e like me Kina, ʻAmelika Hui Pū ʻIa, Iapana, Denemaka, Palani, Romania, a me nā mea ʻē aʻe. He pōhaku Sedimentary siliceous biogenic ia, i haku nui ʻia me nā koena o nā diatoms kahiko.

Loaʻa i loko kahi liʻiliʻi o Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, a me nā mea olaola. ʻO ka maʻamau, ʻoi aku ka nui o SiO2 ma mua o 80%, me ka nui o 94%. ʻO ka nui o ka hao oxide o ka lepo diatomaceous kiʻekiʻe he 1-1.5%, a ʻo ka nui o ka alumini oxide he 3-6%. ʻO ka hui mineral o ka diatomite ʻo Opal a me kona mau ʻano, ukali ʻia e nā minelala lepo hydromica, Kaolinite a me nā ʻōpala mineral. ʻO nā ʻōpala mineral e komo pū ana me ka quartz, feldspar, Biotite a me nā mea olaola.

ʻO ka lepo Diatomaceous i haku ʻia me ka SiO2 amorphous a loaʻa iā ia nā liʻiliʻi o Fe2O3, CaO, MgO, Al2O3, a me nā mea haumia organik. ʻO ka lepo Diatomaceous he melemele māmā a hina māmā paha, palupalu, porous, a māmā. Hoʻohana nui ʻia ia i ka ʻoihana e like me nā mea insulation, nā mea kānana, nā mea hoʻopiha, nā mea wili, nā mea maka aniani wai, nā mea decolorizing, nā mea kōkua kānana honua diatomaceous, nā mea lawe catalyst, a pēlā aku.

Nā Pōmaikaʻi o ka hoʻohana ʻana i ka lepo diatomaceous: pH neutral, ʻaʻohe ʻawaʻawa, hana hoʻokuʻu maikaʻi, hana adsorption ikaika, māmā ka nui o ka nui, ka helu omo ʻaila o 115%, ka maikaʻi mai 325 mesh a 500 mesh, maikaʻi ke kāwili ʻana i ka like, ʻaʻohe ālai ʻana o nā pipeline mīkini mahiʻai i ka wā e hoʻohana ai, hiki ke pāʻani i kahi hana moisturizing i ka lepo, hoʻokuʻu i ka maikaʻi o ka lepo, hoʻolōʻihi i ka manawa momona kūpono, a paipai i ka ulu ʻana o nā mea kanu. ʻOihana momona hui: Mea momona hui no nā mea kanu like ʻole e like me nā huaʻai, nā mea kanu, nā pua a me nā mea kanu. Nā Pōmaikaʻi o ka hoʻohana ʻana i ka lepo diatomaceous: pono e hoʻohana ʻia ka lepo diatomaceous ma ke ʻano he mea hoʻohui i ka sima. Loaʻa i nā huahana hoʻohui uhi honua diatomaceous nā ʻano o ka porosity kiʻekiʻe, ka absorption ikaika, nā waiwai kemika paʻa, ke kū'ē ʻana i ka ʻaʻahu, ke kū'ē wela, a pēlā aku. Hiki iā lākou ke hāʻawi i ka hana ʻili maikaʻi loa, ka hoʻohālikelike, ka mānoanoa, a me ka hoʻomaikaʻi ʻana i ka hoʻopili ʻana no nā uhi. Ma muli o kona nui o ka pore, hiki iā ia ke hoʻopōkole i ka manawa maloʻo o ka uhi. Hiki iā ia ke hoʻemi i ka nui o ka resin i hoʻohana ʻia a hoʻemi i nā kumukūʻai. Ua manaʻo ʻia kēia huahana he huahana matte coating kūpono me ka maikaʻi o ke kumukūʻai, a ua koho ʻia ʻo ia he huahana e nā mea hana uhi honua nui he nui, i hoʻohana nui ʻia i ka lepo diatomaceous wai.
