Kuyini i-Diatomite?

I-Diatomite iyidwala eliyi-sedimentary eliyi-biogenic siliceous sedimentary elakhiwe ngokuyinhloko yizinsalela ze-diatom zasendulo, ezinezakhiwo ezifana nokubhoboka okuphezulu, ukumuncwa, kanye nokuhlunga. Ingxenye eyinhloko ye-diatomite yi-silicon dioxide (SiO₂) engabonakali, evame ukuba ngaphezu kuka-80% futhi ifinyelela ku-94%, kuyilapho futhi iqukethe inani elincane lokungcola njenge-Al₂O₃, i-Fe₂O₃, i-CaO, i-MgO, kanye nezinto eziphilayo. Izakhiwo eziyingqayizivele zomzimba nezamakhemikhali ze-Diatomite ziyenze yaba yinto ebalulekile ezimbonini ezahlukahlukene emhlabeni jikelele, ngezinhlelo zokusebenza ezihlanganisa impilo yansuku zonke, ukukhiqizwa kwezimboni, kanye nokuvikelwa kwemvelo.

1. Ukwakheka kwe-Diatomite: Isimangaliso Sendawo Esakhiwe Yimpilo Nesikhathi Sasendulo

Ingxenye eyinhloko ye-diatomite yizindonga zamaseli e-siliceous (ama-frustules) ama-diatom asendulo—ulwelwe oluncane olwaluhlala olwandle, emachibini, nakwezinye izindawo zamanzi. Ngesikhathi sokuphila kwazo, lezi zinto eziphilayo zazikhipha i-silica encibilikisiwe emanzini ukuze zakhe izindonga zamaseli azo eziyinkimbinkimbi nezingenazo izikhala. Lapho ama-diatom efa, amathambo azo e-silica ahlala phansi kwezindawo zamanzi, eqoqana ngobuningi obukhulu. Ngaphansi kwezimo ezithile zokushisa, ingcindezi, kanye nezimo ze-geological eminyakeni eyizigidi, lawa ma-depositi ancipha futhi ahlukaniswa, aguquka abe yidwala elithambile, elifana ne-chalk esilibiza ngokuthi i-diatomite. Phakathi nale nqubo, isakhiwo esiyinkimbinkimbi sezindawo ezinazo izikhala sama-diatom frustules sagcinwa, ngaleyo ndlela sabeka isisekelo sezakhiwo eziyingqayizivele ze-diatomite.

Namuhla, ama-diatomite asezingeni eliphezulu asatshalaliswa emhlabeni jikelele. Izindawo ezinkulu zokukhiqiza zifaka phakathi i-United States, i-China, i-Denmark, i-Japan, i-France, ne-Mexico. I-China isendaweni yesibili emhlabeni jikelele ezindaweni zokugcina i-diatomite, kanye nama-deposit amakhulu atholakala eNyakatho-mpumalanga ye-China (i-Jilin Changbai Mountain), i-Xinle (i-Hebei), izifunda zasempumalanga, i-Panxi (i-Sichuan), kanye ne-Yunnan esempumalanga naseningizimu-ntshonalanga. Lawa ma-deposit ahlukile ekubunjweni kwamaminerali kanye nezindlela zokucubungula (ezihlukaniswa njenge-gray raw diatomite, i-yellow calcined diatomite, kanye ne-white flux-calcined diatomite), kodwa zonke zigcina izici eziyinhloko ze-diatomite—ubukhulu obuhle kakhulu be-porosity kanye namandla okumunca avela esakhiweni esiyinkimbinkimbi sama-diatom afakwe emafosini.
