What is Diatomite?

He aha ka Diatomite?

ʻO ka honua diatomaceous, i ʻike nui ʻia ʻo ka palaoa mauna, ka pauka mōʻalihaku a i ʻole ka pauka radiolaria, he pōhaku sedimentary siliceous biogenic, ka nui o nā koena siliceous o nā diatoms a me nā microorganisms ʻē aʻe. Nui nā unuhi ʻōlelo Pelekania, i puka ʻia ma nā nūpepa a me nā nūpepa: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
ʻO ka diatomite he pōhaku sedimentary ʻulaʻula māmā i haku ʻia me nā koena iwi iwi siliceous o nā diatoms. He pōhaku porous loa ia me ka nui o nā ʻāpana liʻiliʻi a me ka ʻumekaumaha kikoʻī haʻahaʻa. Hoʻohana kēia mau waiwai iā ia ma ke ʻano he media kānana, he mea hoʻoheheʻe ʻia, a ma ke ʻano he mea hoʻopiha māmā no ka ʻōpala, pena, a me nā plastics. Ke ʻoki ʻia ka diatomite i loko o ka pauka, kapa ʻia ʻo ia he "diatomaceous earth," a i ʻole DE Diatomite Loaʻa mai nā koena o ke kai mōʻalihaku microscopic a i ʻole nā algaes wai maʻemaʻe, ʻo ka diatomite he mineral kūlohelohe maoli i hoʻohana ʻia i nā ʻano noi mai nā mea hoʻonaninani a hiki i ka kānana. .

ʻO ka mea kemika nui o ka honua diatomaceous he silicate. ʻO ka maʻiʻo o SiO2 kekahi o nā hōʻailona o ka maʻiʻo o nā diatoms i ka diatomite ore, aʻo ka SiO2 kiʻekiʻe ka maikaʻi. ʻO ka honua Diatomaceous he 1% ~ 5% ka wai, a ʻo ka mahana o ka wai o ka wai colloidal he 110 ~ 250 ° C.

Hoʻohana i ka honua Diatomite a me Diatomaceous

Hoʻohana pinepine ʻia ka diatomite ma ke ʻano he mea hoʻohui i ka hana ʻana i ka sima portland. Loaʻa ka diatomite kiʻekiʻe ma luna o 80% silica, a ua hoʻohui ʻia i ke kaʻina hana sima e hoʻonui ai i ka ʻike silica o ka huahana. ʻO ka diatomite pololei mai ka mine e ʻoki ʻia a hui ʻia me ka limestone, shale, a i ʻole nā mea ʻē aʻe e hana ʻia ai ka sima.
ʻO nā hoʻohana nui ʻehā o ka diatomite ma ʻAmelika Hui Pū ʻIa i ka makahiki 2017 ʻo ia ka kānana (50%), ka hui māmā (30%), nā mea hoʻopihapiha (15%), a me nā mea hoʻoheheʻe (5%). ʻO nā waiwai o ka diatomite e hoʻohana pono ai i kēia mau noi i helu ʻia ma lalo nei.
