ʻO nā diatoms i lokolepo diatomaceousloaʻa nā ʻano like ʻole, e like me nā disc, nā nila, nā cylinders, nā hulu a pēlā aku. ʻO 0.3～0.5g/cm3 ka mānoanoa nui, 1～1.5 ka paʻakikī Mohs (4.5～5mm nā iwi diatom), 80～90% ka porosity, a hiki iā ia ke komo i ka wai he 1.5～4 manawa o kona kaumaha ponoʻī. He wela ia, He mea hoʻoheheʻe maikaʻi ʻole o ka uila a me ke kani, ka helu heheʻe 1650 ~ 1750 ° C, paʻa kemika kiʻekiʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o kekahi waikawa ikaika koe wale nō ka waika hydrofluoric, akā hiki ke hoʻoheheʻe ʻia i ka hopena alkali ikaika.

ʻO ka hapa nui o ka silica o ka honua diatomaceous he amorphous, a ʻo ka ʻike o ka silicic acid soluble i ka alkali he 50-80%. Lilo ʻo Amorphous SiO2 i crystalline ke hoʻomehana ʻia i 800-1000 ° C, a hiki ke hoʻemi ʻia ka waikawa silicic soluble i ka alkali i 20-30%. 1.5 He ʻano pōhaku ʻo Diatomite me ke ʻano olaola. ʻO ka hapa nui o 80-90%, a ʻo kekahi a ʻoi aku ma mua o 90% o nā frustules diatom. ʻO ka mea kūʻai nui o ka silicon oxide i ka wai kai a me ka wai loko he diatoms, ʻo ia ka diatom sludge. I ka wā o ke kaʻina hana diagenesis, hoʻokumu ʻia ka diatomite ma o ka pae petrochemical. Hoʻokumu ʻia nā pūpū diatom me ka opal. I ka wā o ka ulu ʻana a me ka hana hou ʻana o nā diatoms, hoʻomoʻo ia i ka silica colloidal mai ka wai a hoʻololi mālie i ka opal.

ʻO ka maʻiʻo diatom i lokolepo diatomaceous, ka liʻiliʻi o nā haumia, ʻoi aku ka keʻokeʻo o ke kala a me ka māmā o ka maikaʻi. ʻO ka umekaumaha kikoʻī he 0.4-0.9. No ka nui o nā lua pūpū o ka diatomite, he ʻano porous ka diatomite. ʻO ka porosity o ka diatomite he 90-92%. Loaʻa iā ia ka wai ikaika a me ke alelo pipili. Ma muli o ka liʻiliʻi liʻiliʻi o nā ʻāpana diatom, e hoʻomaʻamaʻa maikaʻi ka honua diatomaceous. ʻAʻole hiki ke hoʻoheheʻe ʻia ka honua diatomaceous i ka waikawa (HCl, H2S04, HN03), akā hiki ke hoʻoheheʻe ʻia i ka HF a me K0H.

Diatomahe ʻano limu pū hoʻokahi i ʻike mua ʻia ma ka honua. Noho ʻo ia i loko o ka wai kai a i ʻole ka wai loko, a he liʻiliʻi loa kona ʻano, ʻo ka maʻamau he liʻiliʻi wale nō a hiki i ka ʻumi microns. Hiki i nā diatoms ke hoʻokō i ka photosynthesis a me nā mea ola kino. Hoʻoulu pinepine a hoʻohua i kahi wikiwiki weliweli. Ua waiho ʻia kona mau koena e hana i ka honua diatomaceous. ʻO kēia diatom ka hāʻawi ʻana i ka oxygen i ka honua ma o photosynthesis a hāpai i ka hānau ʻana o ke kanaka, nā holoholona a me nā mea kanu. ʻO ka mea nui o ka honua diatomaceous he silicic acid. Nui nā pores ma ka ʻili, hiki iā ia ke hoʻomohu a hoʻoheheʻe i ka ʻala ʻokoʻa i ka lewa, a loaʻa iā ia nā hana o ka mālama ʻana i ka haʻahaʻa a me ka deodorization. ʻO nā mea kūkulu hale i hana ʻia me ka hoʻohana ʻana i ka honua diatomaceous e like me nā mea maka ʻaʻole wale nā hiʻohiʻona o ka non-combustibility, dehumidification, deodorization a me ka permeability maikaʻi, akā hiki ke hoʻomaʻemaʻe i ka ea, ke kani ʻana o ke kani, ka wai a me ka wela wela.

ʻO Jilin Yuantong Mining Co., Ltd. he hui ʻoihana e hoʻohui ana i ka mining diatomite, ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ka hana ʻana i nā huahana diatomite series. ʻO ia ka papa maikaʻi loa a me nā mea mālama nui loa o nā minerala like i koʻu ʻāina, a ʻo ia hoʻi nā waihona Diatomite e hoʻomohala nei i kēia manawa. Hoʻopuka nui kā mākou hui i nā huahana diatomite series e like me nā kōkua kānana diatomite, nā hoʻopiha diatomite, a me nā catalysts diatomite. Pono nā huahana i ka maikaʻi a kūpono i ke kumukūʻai, a ua hoʻokipa maikaʻiʻia e nā mea kūʻai.
