I-Diatomite ivela njengento engokwemvelo enobungani nemvelo exhumanisa intuthuko esimeme kanye nomnotho ojikelezayo, ivumelana ngendlela entsha nezidingo ezahlukahlukene zokwakha okuluhlaza, ukuhlanzwa komoya, ukuhlunga kwezimboni, kanye nokufakwa kokushisa kwezimboni. Ngokungafani nezinto zokwenziwa ezithembele ekukhiqizeni amandla aphezulu noma ekukhipheni izinto ezinobuthi, i-diatomite ivela kuma-diatom afakwe emafossil—izinto eziphilayo zasemanzini ezincane ezazichuma olwandle nasemachibini asendulo eminyakeni eyizigidi edlule. Lezi zinto eziphilayo zazinezindonga zamaseli ezisekelwe ku-silica, futhi njengoba zifa, izinsalela zazo zaqongelela futhi zafakwa emafossil eminyakeni eyizinkulungwane, zakha ama-deposit acebile ezakhiweni ze-silica ezinezimbobo. Lo msuka oyingqayizivele unikeza i-diatomite isakhiwo esingenayo izimbobo kanye namandla aqinile okumunca, izici ezenza ivelele kakhulu ezintweni zezimboni ezivamile. Isebenza njengengxenye eyinhloko ekuhlobiseni kwangaphakathi, ekuhlungeni amanzi, ekumbozeni okuvimbela umlilo, ngisho nasezintweni zezimoto, i-diatomite isibe yinto ebalulekile emikhakheni eminingi. Njengoba imiphakathi iphishekela intuthuko eqaphela imvelo futhi egcina amandla, i-diatomite idlula izindima zomsebenzi owodwa ukuze ibe yisisombululo sezinhloso eziningi esihlanganisa izakhiwo zemvelo, ukusebenza kahle, kanye nomthwalo wemfanelo wezemvelo, iletha inani elibonakalayo kuzo zonke izintambo zezimboni kusukela ekwakheni kuya ekukhiqizeni.

Enye yezindlela ezivelele kakhulu zokusebenzisa i-diatomite isezakhiweni eziluhlaza, lapho ukuvikela kwayo ukushisa kanye nokuphefumula kwayo kudala izinzuzo ezinkulu zokonga amandla. Ezinhlelweni zodonga lwangaphandle, amabhodi okuvikela asekelwe ku-diatomite—axutshwe nezihlanganisi ezinobungani nemvelo ezifana ne-starch derivatives noma i-lignin—akha ungqimba olulula kodwa oluhlala isikhathi eside olunciphisa ukudluliselwa kokushisa ngamaphesenti amakhulu (ukugwema izinombolo, ezichazwa ngokuthi “izinga eliphawulekayo”). Lokhu akugcini nje ngokunciphisa ukusetshenziswa kwamandla okushisa ebusika kanye nokupholisa ehlobo kodwa futhi kuvimbela ukuminyana ezindaweni zodonga ngokuvumela umswakama ukuba uphume, kugweme ukukhula kwesikhunta futhi kwandise isikhathi sokuphila kwesakhiwo ngeminyaka. Isibonelo, ezindaweni zokukhiqiza ezinezindawo ezinkulu ezivulekile kanye nokushintshashintsha kwezinga lokushisa okuvamile, izendlalelo zokuvikela ze-diatomite ezisetshenziswa ophahleni nasezindongeni zigcina amazinga okushisa angaphakathi azinzile, kunciphisa umthwalo emishinini yokushisa nokupholisa ngokunciphisa isikhathi sokusebenza. Ekwakhiweni kwangaphakathi okuhlakaniphile, amaphaneli odonga asekelwe ku-diatomite ahlangana ngaphandle kokuphazamiseka nezinzwa zomswakama ukuze kufezwe ukulawulwa okuguquguqukayo. Lapho umswakama wangaphakathi ukhuphuka ngaphezu kwezinga elikhululekile—okuvamile ezindaweni ezisogwini noma ngezikhathi zemvula—isakhiwo samaphaneli esinezimbobo sibamba umswakama owedlulele, siwugcine ngaphakathi kwezimbobo ezincane. Uma umswakama wehla ngezikhathi ezomile noma ezindaweni ezifudumele, amaphaneli akhipha umswakama ogciniwe ngesenzo se-capillary, okudala indawo yangaphakathi elinganisiwe ngokwemvelo ngaphandle kokuthembela kuma-humidifier kagesi asebenzisa amandla noma ama-dehumidifier. Lawa maphaneli anikeza nokuthungwa kwemvelo okuhlukahlukene, kusukela ekuqedweni okubushelelezi oku-matte okufanele izikhala zehhovisi ezincane kuya ezindaweni ezi-granular ezihambisana nokuhlobisa kwezindlu zasemaphandleni, okuhlanganisa ukusebenza okusebenzayo nokukhanga kobuhle.

Isisekelo semithombo ye-Diatomite sihlanganisa ubuningi bemvelo kanye nokuvumelana kwemvelo, sihlinzeka ngokutholakala okuzinzile ngenkathi kunciphisa ukuphazamiseka kwemvelo. I-Diatomite yakheka phakathi kwezigidi zeminyaka yokuqongelela kwe-diatom ezitsheni zasolwandle noma zamanzi ahlanzekile, kanye nama-deposit ahluka kakhulu ngendawo yokuhlala ukuze kuhlangatshezwane nezidingo ezahlukene zokusetshenziswa. I-Marine diatomite, eyakhiwe ezindaweni ezijulile zolwandle ezinosawoti ozinzile kanye nokushisa, ine-pores encane, eqinile—eminye emincane njenge-nanoscale—kanye namandla okumunca aqinile. Indawo yayo yangaphakathi ngesisindo seyunithi inkulu kakhulu, ivame ukufana nama-adsorbents akhethekile okwenziwa, okwenza kube kuhle kakhulu ekuhlanzweni komoya kanye nokuhlungwa kwamanzi okunembile kakhulu. Ama-deposit aseduze nezifunda zasolwandle ezisenyakatho, njengalawo asenyakatho yeScandinavia, aziswa kakhulu ngama-pores awo amahle kakhulu, athuthukisa ukumunca ukungcola okuncane njenge-PM2.5 kanye namakhemikhali e-organic aguquguqukayo njenge-formaldehyde ne-benzene. I-Diatomite yamanzi ahlanzekile, eqongelelwe emachibini asendulo kanye nasezindaweni zase-delta zomfula ezinezimo zemvelo ezinamandla kakhulu, ine-pores ezinkulu, ezixhumene kanye nokuphefumula okungcono kakhulu. Ama-depositi asemachibini amakhulu ahlanzekile njengalawo asempumalanga ye-Afrika noma e-Asia ephakathi, anokuqukethwe okuphansi kwamaminerali kanye nobumsulwa obukhulu be-silica, anikeza ukulawulwa komswakama okumangalisayo, okwenza afanelekele ukuhlobisa izakhiwo eziluhlaza kanye nengaphakathi. Ukukhishwa kwe-diatomite kunamathela emithethweni eqinile enobungani nemvelo ukuvikela izindawo zemvelo ezibuthakathaka: ukumbiwa komhlaba kwamukelwa kuphela ukugwema umonakalo omkhulu we-geological, futhi izindawo zokumba zibuyiselwa esimweni semvelo ngendlela ehlelekile. Lokhu kufaka phakathi ukutshala kabusha utshani bendabuko nezitshalo zasemanzini ukuze kubuyiselwe ibhalansi yenhlabathi namanzi, ukwakha izindawo ezimanzi zokwenziwa ukuze kuhlungwe amanzi agelezayo ezindaweni zokumba, kanye nokubeka eceleni izindawo ezivikelwe ezizungezile ama-depositi ukuze kulondolozwe ukuhlukahlukana kwendawo. Izimiso zomnotho ojikelezayo ziyasetshenziswa kakhulu ekusetshenzisweni kabusha kwemfucuza: izinsalela eziqinile ezikhiqizwa ngesikhathi sokuhlanzwa kwe-diatomite, ezisagcina isakhiwo esinezimbobo ezithile, zigaywa zibe yifomu le-granular ukuze kusetshenziswe ukuhlunga kwezimboni njengokuhlanzwa kwamafutha noma ukucubungula amakhemikhali. Uthuli oluncane olukhiqizwa ngesikhathi sokugaya nokuhlukaniswa luphinde lusetshenziswe lube izithasiselo zopende wangaphakathi kanye nopende, kuthuthukiswe ukuphefumula kopende kanye nokusebenza kokumuncwa ngenkathi kunciphisa imfucuza. Ngisho namanzi angcolile avela ezinqubweni zokugaya ezimanzi aphathwa ngokuthungwa kanye nokuhlunga, bese esetshenziswa kabusha emijikelezweni yokukhiqiza elandelayo, kungashiyi cishe imfucuza yezinsiza kulo lonke uchungechunge lokuhlinzeka.

Izinqubo zokukhiqiza ze-Diatomite zaklanywa ngokucophelela ukuze zilondoloze izakhiwo zayo eziyinhloko ngenkathi zinciphisa umthelela emvelweni, zithembele ezindleleni ezibonakalayo ezigwema umonakalo wamakhemikhali. Isihluthulelo sokugcina isakhiwo esinezimbobo kanye namandla okumunca sisezindleleni zokucubungula ezithambile: ukugaya okomile okusheshayo okuphansi kwamukelwa kabanzi esikhundleni sokucubungula okushisa okuphezulu, njengoba ukushisa okukhulu ngaphezu kwamazinga aphakathi kungabhidliza isakhiwo se-silica pore esibucayi. Imishini yokugaya isebenza ngesivinini esijikelezayo esilinganiswe ngokucophelela ukuqinisekisa ukuthi izinhlayiya zichotshozwa zibe osayizi abafunwayo ngaphandle kokucindezela izimbobo zangaphakathi, kulondolozwa ukusebenza kahle kokumunca kwezinto. Ukuhlukaniswa komoya, indlela yokuhlunga engenamakhemikhali esebenzisa ukuhamba komoya okulawulwayo, ihlukanisa izinhlayiya ngobukhulu, ifanelana kahle nezidingo zohlelo lokusebenza ezahlukene. Impuphu ecolekile kakhulu, enezinhlayiya ezincane ngokwanele ukudlula ezihlungweni ezinhle, isetshenziselwa izihlungi zomoya ezisebenzayo kakhulu kanye nokuhlanzwa kwamanzi okunembile; impuphu ephakathi nendawo ilungele ukumbozwa kwangaphakathi namaphaneli odonga, ilinganisela ukuphefumula nokuqina; ama-granule amakhulu agcinelwe ukuhlunga kwezimboni kanye nokufakwa kokushisa, lapho ukuzinza kwesakhiwo kubalulekile khona. Ukuze i-diatomite ehlanzekile kakhulu idingeke ekusetshenzisweni okunembile njengokwelashwa kwamanzi embonini kagesi noma ukukhiqizwa kwe-semiconductor, kusetshenziswa ukugaya okumanzi okuvaliwe. Le nqubo isebenzisa amanzi aphinde asetshenziswa kabusha angenawo ama-ion njengendlela yokugaya ukuvimbela ukungcola, futhi amanzi aphathwa ngokushintshana kwama-ion kanye nokuhlunga ngaphambi kokuba asetshenziswe kabusha ohlelweni oluvaliwe, okugwema ngokuphelele ukukhishwa kwamanzi angcolile. Ubuchwepheshe obusha bokusebenza obusezingeni eliphansi lokushisa buthuthukisa kakhulu amandla okumunca ngaphandle kokulimaza ama-pores: i-diatomite iphathwa emazingeni okushisa aphakathi ezindaweni ezilawulwayo ukuze kususwe ukungcola okungokwemvelo kanye nokuvula ama-pores avinjiwe, okuthuthukisa kakhulu ikhono layo lokubamba ukungcola. Ukomisa okusebenzisa amandla elanga kusetshenziswa kabanzi esigabeni sokugcina sokucubungula, kushintsha ukushisa okusekelwe kuphethiloli ukuze kuncishiswe ukunyathela kwekhabhoni ngomkhawulo omkhulu. Ukulawulwa kwekhwalithi kuhlanganiswe kuyo yonke ikhiqizo: ibhetshi ngalinye le-diatomite lihlolwa isakhiwo sama-pore kusetshenziswa amathuluzi okumunca i-nitrogen ukuze kulinganiswe indawo engaphezulu kanye nokusatshalaliswa kosayizi wama-pore, ukuqinisekisa ukusebenza kokumunca kuhlangabezana nezindinganiso zokusetshenziswa. Ezintweni zokwakha, ukuhlolwa kokuphefumula kwenziwa kusetshenziswa amakamelo omswakama ukuqinisekisa amakhono okulawula umswakama, kuyilapho amazinga okuhlunga ezimboni ehlolwa ukuwa kokucindezela ukuqinisekisa ukusebenza kahle kokugeleza. Lezi zinqubo eziqinile azigcini nje ngokugcina izici zemvelo ze-diatomite ezinobungani nemvelo kodwa futhi zithuthukisa ukusebenza kwayo ezimweni ezithile, ukuqinisekisa ukuhambisana nokuthembeka ekusetshenzisweni okusebenzayo.

Izakhiwo eziyinhloko ze-Diatomite zenza ukuthi ingathathelwa indawo yizimboni eziningi, kanti isici ngasinye sisekelwe emvelaphi yaso ehlukile ye-geological. Isakhiwo esinezimbobo, esakhiwe yizindonga zamaseli e-silica ezifakwe i-fossilized zama-diatom, siqukethe izimbobo ezincane ezingenakubalwa ezixhumanisayo ezidala indawo enkulu yangaphakathi. Lesi sakhiwo sisebenza njengesiponji esincane, senza amandla okumunca aqinile abamba amakhemikhali e-organic aguquguqukayo, uthuli, impova, kanye nephunga emoyeni, futhi simunce izinsimbi ezisindayo njenge-lead ne-mercury, izinto eziqinile ezilengisiwe, kanye nokungcola kwemvelo emanzini. Ngokungafani nama-adsorbents okwenziwa athembele ekumbozweni kwamakhemikhali, ukumuncwa kwe-diatomite kungokomzimba, okusho ukuthi ingavuselelwa ngokushisa noma ukuwasha, kwandise impilo yayo yesevisi futhi kuncishiswe imfucuza. Ukuphefumula kanye nokulawulwa komswakama, okuhlobene kakhulu nesimo sayo esinezimbobo, kuvumela ukulawulwa komswakama okuguquguqukayo ezindaweni ezivalekile. Ezindaweni zangaphakathi, izinto ze-diatomite zimunca umswakama owedlulele ngezikhathi zomswakama ukuvimbela ukukhula kwesikhunta ezindongeni nasefenisha, futhi kukhishwe umswakama ogciniwe ngezikhathi zokomile ukuze kugcinwe izinga lomswakama elikhululekile, kunciphisa ukungakhululeki kokuphefumula okubangelwa umoya owomile. Ukuzinza kwamakhemikhali kungenye imfanelo ebalulekile: i-diatomite ayisebenzi kuma-asidi nama-alkali avamile, ngaphandle kwe-hydrofluoric acid enamandla, okwenza ifaneleke ukusetshenziswa isikhathi eside ezindaweni zezimboni ezinamakhemikhali kanye nezikhala zangaphakathi ezinamazinga e-pH ahlukahlukene. Ukushisa okushisayo, okutholakala emoyeni ovalelekile ngaphakathi kwemigodi yayo, kunezela inani elikhulu ekusetshenzisweni kwezakhiwo eziluhlaza. Uma ixutshwe emabhodini odonga noma ezimbozweni, i-diatomite inciphisa ukudluliselwa kokushisa ngokudlulisa kanye nokudlulisa umoya, inciphise ukusetshenziswa kwamandla okushisa noma ukupholisa futhi yehlise ukukhishwa kwekhabhoni. Ngaphezu kwalokho, i-diatomite ibonisa izakhiwo zemvelo ezivimbela umlilo: ukwakheka kwayo kwe-silica akushi, futhi isakhiwo sayo esinezimbobo sibamba ukushisa, sinciphise ukusabalala kwamalangabi futhi sinciphise ukukhiqizwa kwentuthu ezimweni zomlilo.

I-Diatomite iphumelela kakhulu ezimweni ezintsha ezahlukahlukene ngaphandle kwezicelo zendabuko. Ezimbozweni ezivimbela umlilo ezakhiweni zezentengiselwano kanye nezindawo zezimboni, i-diatomite ixutshwa nezihlanganisi ezinobungani nemvelo kanye nezithibi zomlilo ukuze kwakheke ungqimba oluvikelayo. Uma ivezwa emazingeni okushisa aphezulu, i-diatomite iyanda kancane ukuze yakhe isithiyo sokuvimbela imfucuza esinezimbobo, inciphise ukudluliselwa kokushisa ezintweni ezingaphansi futhi ivimbele ukuwa kwesakhiwo. Lolu hlelo lokusebenza lubaluleke kakhulu ezindaweni zokugcina izinto kanye nezitshalo zokukhiqiza lapho ukuphepha komlilo kubalulekile khona. Imboni yezimoto isebenzisa i-diatomite njengesigcwalisi sezinto zokuvimbela umsindo zangaphakathi kwezimoto. Isakhiwo sayo esinezimbobo simunca amaza omsindo, sinciphise umsindo womgwaqo kanye nokudlidliza kwenjini ngaphakathi kwekhabhini, sithuthukise induduzo yabagibeli ngenkathi sithatha indawo yezinto zokuvimbela umsindo ezenziwe ngokwenziwa ezithembele ezintweni ezisuselwe kuphethiloli. Ekuhlanzweni komoya, izihlungi zomoya we-particulate (HEPA) ezisebenza kahle kakhulu zivame ukufaka i-diatomite ukuze kuthuthukiswe ukubanjwa kokungcola. Izihlanzi zomoya zasekhaya ezisebenzisa izihlungi ezisekelwe ku-diatomite zibamba ngempumelelo uthuli oluncane, impova, kanye ne-dander yezilwane ezifuywayo, kuyilapho izihlungi zezinga lezimboni zisusa izinhlayiya ezinobuthi njenge-heavy metal oxides ezivela ekukhishweni kwefektri, zithuthukisa ikhwalithi yomoya emiphakathini ezungezile. Izicelo zokuhlunga amanzi zidlulela ngale kwamanzi okuphuza kuya ekuhlanzweni kwamanzi amdaka ezimbonini: i-diatomite enezinhlayiya isetshenziswa ezinhlelweni zokuhlunga ezinezigaba eziningi zezimboni zezindwangu, isusa izinsalela zodayi kanye nezinto eziqinile ezilengisiwe emanzini amdaka ngaphambi kokuba akhishwe noma aphinde asetshenziswe. Embonini ye-elekthronikhi, i-diatomite ehlanzekile kakhulu isetshenziswa njengendawo yokuhlunga ekukhiqizweni kwamanzi ahlanzekile kakhulu, iqinisekisa ukuthi amanzi asetshenziswa ekukhiqizeni ama-semiconductor awanazo izinto ezingcolisayo ezingalimaza izingxenye ezibucayi. Izicelo zokuhlobisa ngaphakathi ziyaqhubeka nokukhula, kanti amathayili ophahla asekelwe ku-diatomite athola ukuthandwa emahhovisi nasezikoleni. Lawa mathayili ahlanganisa ukumuncwa komsindo, ukulawulwa komswakama, kanye nokumelana nomlilo, okudala izindawo zangaphakathi ezinempilo neziphephile. Ngisho nasebucikweni nasemisebenzini yobuciko, i-diatomite isetshenziswa njengesandisi se-pigment semvelo, ithuthukisa ukugeleza nokuqina kwamapende asekelwe emanzini ngenkathi igcina izimfanelo zayo ezinobungani nemvelo.

Ukulawulwa kwekhwalithi ye-Diatomite kulungiselelwe izinhlelo zokusebenza ezithile, ngezinqubo zokuhlola eziqinile ukuqinisekisa ukuhambisana kokusebenza. Kumazinga okuhlunga umoya namanzi, ukuhlolwa kokusebenza kahle kokumuncwa kwenziwa kusetshenziswa izixazululo zokungcola ezijwayelekile noma izingxube zegesi. Isibonelo, ukuhlolwa kokumuncwa kwe-formaldehyde kulinganisa ukuthi ingakanani igesi ebanjwe yisisindo esithile se-diatomite esikhathini esibekiwe, kuyilapho ukuhlolwa kokumuncwa kwensimbi esindayo kuhlaziya amazinga okungcola emanzini ngaphambi nangemva kokuhlunga. Ukuhlaziywa kosayizi we-pore kwenziwa kusetshenziswa izindlela zokungena kwe-mercury porosimetry noma izindlela zokumuncwa kwe-nitrogen ukuqinisekisa ukuthi isakhiwo se-pore sihambisana nokungcola okuqondiwe—ama-pores amancane amakhemikhali e-organic aguquguqukayo kanye nama-pores amakhulu ezinto eziqinile ezilengisiwe. Ezintweni zokwakha ezifana namabhodi okushisa kanye namaphaneli odonga, ukuhlolwa kokushisa kulinganisa amazinga okudlulisa ukushisa ukuqinisekisa ukusebenza okonga amandla, kuyilapho ukuhlolwa kokuphefumula kusebenzisa amakamelo alawulwa yisimo sezulu ukulingisa izimo ezimanzi nezomile, kuqapha amazinga okumuncwa komswakama kanye namazinga okukhululwa. Imikhiqizo ye-diatomite evimbela umlilo idlula ekuhlolweni kokushiswa okuqondile ukuhlola ukusabalala komlilo kanye nokukhiqizwa komusi, ukuqinisekisa ukuhambisana nezindinganiso zokuphepha zezimboni. Ezintweni zokuvimbela umsindo zezimoto, ukuhlolwa kwe-coefficient yokumuncwa komsindo kulinganisa ukuthi angakanani amandla omsindo amuncwa ngamaza ahlukene. Izinsalela ze-diatomite eziphinde zasetshenziswa zihlolwa ngokuqinile ukuze kususwe ukungcola okufana nezinsimbi ezisindayo noma ukungcola okungokwemvelo, kulandelwe ukuhlolwa kokusebenza ukuqinisekisa ukuthi zihlangabezana nezindinganiso ezifanayo neze-diatomite emsulwa. Abakhiqizi abaningi baphishekela nezitifiketi ezivela eceleni zokukhiqiza okunobungani nemvelo, okuqinisekisa ukuthi izindlela zokukhipha nokucubungula ziyahlangabezana nezindinganiso zokusimama zomhlaba wonke. Lezi zinyathelo eziphelele zokulawula ikhwalithi ziqinisekisa ukuthi imikhiqizo ye-diatomite iletha ukusebenza okuthembekile kuzo zonke izinhlelo zokusebenza ezahlukahlukene, kwakha ukwethembana phakathi kwezimboni kanye nabathengi ngokufanayo.
