I-Diatomaceous earth uhlobo lwedwala le-siliceous elisakazeke kakhulu emazweni afana ne-China, i-United States, i-Japan, i-Denmark, i-France, i-Romania, njll. Liyidwala le-sedimentary le-siliceous le-biogenic, eliqukethe kakhulu izinsalela zama-diatoms asendulo.

Iqukethe inani elincane le-Al2O3, i-Fe2O3, i-CaO, i-MgO, i-K2O, i-Na2O, i-P2O5, kanye nezinto eziphilayo. I-SiO2 ivame ukubala ngaphezu kuka-80%, kanti inani eliphezulu lingu-94%. Okuqukethwe kwe-iron oxide yomhlaba we-diatomaceous osezingeni eliphezulu ngokuvamile kungu-1-1.5%, kanti okuqukethwe kwe-aluminium oxide kungu-3-6%. Ukwakheka kwamaminerali kwe-diatomite ikakhulukazi yi-Opal kanye nezinhlobo zayo, kulandelwe amaminerali obumba i-hydromica, i-Kaolinite kanye nezinsalela zamaminerali. Izinsalela zamaminerali zifaka i-quartz, i-feldspar, i-Biotite kanye nezinto eziphilayo.

I-Diatomaceous earth yakhiwe yi-amorphous SiO2 futhi iqukethe inani elincane le-Fe2O3, CaO, MgO, Al2O3, kanye nokungcola okungokwemvelo. I-Diatomaceous earth ivame ukuba phuzi noma ingwevu ekhanyayo, ithambile, inezimbobo, futhi ilula. Ivame ukusetshenziswa embonini njengezinto zokuvikela, izinto zokuhlunga, izigcwalisi, izinto zokugaya, izinto zokusetshenziswa zeglasi yamanzi, izinto zokususa umbala, izinsiza zokuhlunga umhlaba ze-diatomaceous, izithwali ze-catalyst, njll.

Izinzuzo zokusebenzisa umhlaba we-diatomaceous: i-pH engathathi hlangothi, ayinabo ubuthi, ukusebenza kahle kokumiswa, ukusebenza okunamandla kokumuncwa, ubuningi obukhanyayo, izinga lokumuncwa kwamafutha elingu-115%, ubuncane obusukela ku-mesh engu-325 kuya ku-mesh engu-500, ukufana okuhle kokuxuba, ukungavimbeki kwamapayipi emishini yezolimo ngesikhathi sokusetshenziswa, kungadlala indima yokufumisa enhlabathini, kukhulule ikhwalithi yomhlabathi, kwandise isikhathi esisebenzayo somanyolo, futhi kukhuthaze ukukhula kwezitshalo. Imboni yomanyolo ohlanganisiwe: Umanyolo ohlanganisiwe wezitshalo ezahlukahlukene njengezithelo, imifino, izimbali nezitshalo. Izinzuzo zokusebenzisa umhlaba we-diatomaceous: umhlaba we-diatomaceous kufanele usetshenziswe njengesithasiselo ku-samente. Imikhiqizo yesithasiselo se-diatomaceous earth coating inezimpawu zokubhoboka okuphezulu, ukumuncwa okunamandla, izakhiwo zamakhemikhali ezizinzile, ukumelana nokuguguleka, ukumelana nokushisa, njll. Zinganikeza ukusebenza okuhle kakhulu kobuso, ukuhambisana, ukuqina, kanye nokunamathela okuthuthukisiwe kwezingubo. Ngenxa yobuningi bayo obukhulu be-pore, inganciphisa isikhathi sokomisa sengubo. Kungaphinde kunciphise inani le-resin esetshenzisiwe futhi kunciphise izindleko. Lo mkhiqizo ubhekwa njengomkhiqizo osebenza kahle wokumboza ongasebenzi kahle futhi onezindleko ezinhle, futhi uqokwe njengomkhiqizo ngabakhiqizi abaningi abakhulu bokumboza bamazwe ngamazwe, osetshenziswa kabanzi odakeni lwe-diatomaceous olusekelwe emanzini.
