ʻO nā hiʻohiʻona microstructure o ka diatomite

ʻO ka hui kemika o ka honua diatomaceous ka nui o SiO2, akā ʻo kona ʻano he amorphous, ʻo ia hoʻi, amorphous. Ua kapa ʻia kēia amorphous SiO2 he opal. ʻOiaʻiʻo, he SiO2 colloidal amorphous i loko o ka wai, hiki ke hōʻike ʻia ʻo SiO2⋅nH2O. Ma muli o nā wahi hana like ʻole, ʻokoʻa ka nui o ka wai; pili ka microstructure o nā laʻana diatomite i nā ʻano o nā diatoms i waiho ʻia. Ma muli o nā ʻano like ʻole o nā diatoms, ka microscopic structure o ka diatomite ore i hoʻokumu ʻia Aia nā ʻokoʻa ʻokoʻa i ke ʻano, no laila aia nā ʻokoʻa i ka hana. ʻO kēia ka waihona diatomite i hoʻokumu nui ʻia e nā waihona terrestrial ma kekahi wahi o ko mākou ʻāina a mākou i aʻo ai, a ʻo nā diatoms he laina laina.

Ka hoʻohana ʻana i ka diatomite

Ma muli o ka microstructure kūʻokoʻa o ka diatomite, loaʻa iā ia ka nui o nā noi ma nā ʻano he nui e like me nā mea kūkulu hale, nā kemika, ka mahiʻai, ka mālama ʻana i ke kaiapuni, ka meaʻai, a me ka ʻenehana kiʻekiʻe. Ma Iapana, hoʻohana ʻia ka 21% o ka honua diatomaceous i ka ʻoihana hale hale, 11% i hoʻohana ʻia i nā mea refractory, a ʻo 33% i hoʻohana ʻia i nā mea lawe a me nā mea hoʻopihapiha. I kēia manawa, ua loaʻa iā Iapana nā hopena maikaʻi i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea kūkulu hale hou.

I ka hōʻuluʻulu ʻana, ʻo nā noi nui o ka diatomite:

(1) E hoʻohana i kona ʻano microporous e hoʻomākaukau i nā mea kōkua kānana a me nā kākoʻo catalyst. ʻO kēia kekahi o nā hoʻohana nui o ka honua diatomaceous. Hoʻohana piha ia i nā ʻano microstructure o ka honua diatomaceous. Eia naʻe, ʻoi aku ka maikaʻi o ka waiwai o ka honua diatomaceous e like me ke kōkua kānana i nā corinosites, a ʻoi aku ka maikaʻi o ka lepo diatomaceous me ka linear algae structure ma ke ʻano he catalyst carrier no ka mea he nui loa ka ʻili o loko o ka linear algae.

(2) Hoʻomākaukau i ka mālama wela a me nā mea refractory. Ma waena o nā mea hoʻonā wela ma lalo o 900 ° C, diatomite thermal insulation refractory bricks ke koho maikaʻi loa, ʻo ia kekahi o nā kahua noi nui o nā mines diatomite ma koʻu ʻāina.

(3) Hiki ke hoʻohana ʻia ka honua diatomaceous e like me ke kumu nui o ka SiO2 ikaika. No ka mea, he amorphous ka SiO2 ma ka honua diatomaceous, he kiʻekiʻe kona reactivity. No ka laʻana, maikaʻi loa ka hoʻohana ʻana iā ia e hana me nā mea calcareous maka no ka hoʻomākaukau ʻana i nā mea pale ahi. ʻOiaʻiʻo, pono e hoʻoneʻe ʻia kekahi mau haumia mai ka haʻahaʻa haʻahaʻa diatomite ore.

(4) E hoʻohana i kāna mau hiʻohiʻona microporous adsorption e hoʻomākaukau i nā mea antibacterial a me nā antifungal. ʻO kēia kekahi o nā noi nui hou o ka diatomite, kahi mea hana me nā hopena kaiaola. ʻO ka lōʻihi o ka bacillus he 1-5um, ʻo ke anawaena o ka cocci he 0.5-2um, a ʻo ka nui o ka pore o ka honua diatomaceous he 0.5um, no laila hiki i ka mea kānana i hana ʻia i ka honua diatomaceous hiki ke wehe i ka bacteria, inā pili ia i ka mea kānana honua diatomaceous. hoʻohui ʻia i nā mea ʻē aʻe e hoʻokō i ke kumu o ka hoʻokuʻu lohi a me nā hopena lōʻihi. I kēia manawa, hiki i nā kānaka ke hoʻohana i nā mea ʻenehana kiʻekiʻe e hoʻomākaukau ai i ka honua diatomaceous-type anti-mildew a me nā mea hana antibacterial me ka honua diatomaceous ma ke ʻano he mea lawe.
