Izici ze-microstructure ze-diatomite

Ukwakheka kwamakhemikhali omhlaba we-diatomaceous ikakhulukazi i-SiO2, kodwa ukwakheka kwawo ku-amorphous, okungukuthi, i-amorphous. Le SiO2 e-amorphous ibizwa nangokuthi i-opal. Eqinisweni, i-amorphous colloidal SiO2 equkethe amanzi, engavezwa njenge-SiO2⋅nH2O. Ngenxa yezindawo ezihlukene zokukhiqiza, okuqukethwe kwamanzi kuhlukile; i-microstructure yamasampuli e-diatomite ihlobene kakhulu nezinhlobo zama-diatom afakiwe. Ngenxa yezinhlobo ezahlukene ze-diatom, isakhiwo esincane se-diatomite ore esakhiwe Kukhona umehluko osobala wesakhiwo, ngakho-ke kukhona umehluko ekusebenzeni. Okulandelayo idiphozithi ye-diatomite eyakhiwe ikakhulukazi ngamadiphozithi asemhlabeni endaweni ethile ezweni lakithi esiyifundile, futhi ama-diatom ahambisana ngokuyinhloko.

Ukusetshenziswa kwe-diatomite

Ngenxa ye-microstructure eyingqayizivele ye-diatomite, inohlu olubanzi lwezinhlelo zokusebenza emikhakheni eminingi efana nezinto zokwakha, amakhemikhali, ezolimo, ukuvikelwa kwemvelo, ukudla, kanye nobuchwepheshe obuphezulu. E-Japan, i-21% yomhlaba we-diatomaceous isetshenziswa embonini yezinto zokwakha, i-11% isetshenziselwa izinto eziphikisayo, kanti i-33% isetshenziselwa abathwali nabagcwalisi. Njengamanje, iJapane isizuze imiphumela emihle ekuthuthukisweni nasekusetshenzisweni kwezinto ezintsha zokwakha.

Kafushane, ukusetshenziswa okuyinhloko kwe-diatomite yilezi:

(1) Sebenzisa isakhiwo sayo se-microporous ukuze ulungise izinto ezihlukahlukene zosizo lwesihlungi kanye nezisekelo ze-catalyst. Lokhu kungenye yezindlela ezisetshenziswa kakhulu zomhlaba we-diatomaceous. Isebenzisa ngokugcwele izici ze-microstructure yomhlaba we-diatomaceous. Kodwa-ke, i-diatomaceous earth ore esetshenziswa njengesisefo kungcono ukuthi inothe kuma-corinosites, kanti i-diatomaceous earth ore enesakhiwo se-algae esiwumugqa njengesithwali se-catalyst ingcono ngoba ulwelwe oluqondile lunendawo enkulu kakhulu yangaphakathi.

(2) Ukulungiswa kokugcina ukushisa kanye nezinto eziphikisayo. Phakathi kwezinto zokufakelwa ezishisayo ezingaphansi kuka-900 ° C, izitini ze-diatomite ezishisayo zokufakelwa kwe-thermal ziyisinqumo esihle kunazo zonke, okungenye yezinkambu eziyinhloko zokusetshenziswa kwezimayini ze-diatomite ezweni lami.

(3) Umhlaba we-Diatomaceous ungasetshenziswa njengomthombo oyinhloko we-SiO2 esebenzayo. Njengoba i-SiO2 emhlabeni we-diatomaceous i-amorphous, inokuphinda isebenze okuphezulu. Isibonelo, kuhle kakhulu ukuyisebenzisa ukuze usabele ngezinto ezingavuthiwe ze-calcareous ukuze ulungise izinto ezingashi umlilo ze-calcium silicate board. Yiqiniso, okunye ukungcola kufanele kususwe ku-diatomite ore yezinga eliphansi.

(4) Sebenzisa izici zayo ze-microporous adsorption ukuze ulungiselele ama-antibacterial and antifungal agents. Lokhu futhi kungenye yezinhlelo zokusebenza ezintsha ezibalulekile ze-diatomite, okuyizinto ezisebenzayo ezinemiphumela yemvelo. Ubude be-bacillus ngokuvamile bungu-1-5um, ububanzi be-cocci bungu-0.5-2um, kanti ubukhulu bembobo yomhlaba we-diatomaceous bungu-0.5um, ngakho-ke isici sokuhlunga esenziwe nge-diatomaceous earth singasusa amagciwane, uma sinamathiselwe ku-diatomaceous earth filter element Ama-antibacterial agents kanye ne-photosensitizers abe nemiphumela engcono ye-antibacterial and bactericidal inhloso yokukhishwa kancane kanye nemiphumela yesikhathi eside. Manje, abantu bangasebenzisa izindlela zobuchwepheshe obuphezulu ukuze balungiselele i-diatomaceous earth-type anti-mildew nezinto zokusebenza ezilwa namagciwane ezinomhlaba we-diatomaceous njengesithwali.
