I-Diatomaceous Earth iwuhlobo lwamatshe e-siliceous ikakhulukazi asakazwa emazweni afana ne-China, i-United States, i-Japan, i-Denmark, i-France, i-Romania, njll. Idwala le-biogenic siliceous sedimentary ikakhulukazi elakhiwe izinsalela zama-diatoms asendulo.Ukwakhiwa kwamakhemikhali ayo ngokuyinhloko yi-SiO2, engamelwa yi-SiO2 · nH2O, futhi ukwakheka kwayo kwamaminerali kuyi-opal kanye nezinhlobonhlobo zayo.Izinqolobane zomhlaba we-diatomaceous eShayina zingamathani ayizigidi ezingama-320, nendawo engase igcinwe engaphezu kwamathani ayizigidi eziyizinkulungwane ezimbili, ikakhulukazi eMpumalanga China naseNyakatho-mpumalanga yeChina.Phakathi kwazo, iJilin (54.8%, eneDolobha laseLinjiang esiFundazweni saseJilin ebalwa neziqiwi zokuqala ezifakazelwe e-Asia), iZhejiang, Yunnan, Shandong, Sichuan, nezinye izifundazwe zinokusatshalaliswa okubanzi, kepha inhlabathi esezingeni eliphakeme igxiliwe kuphela Indawo yaseChangbai Mountain yaseJilin, kanye nezinye izimbiwa eziningi ziyinhlabathi yebanga lesi-3-4.Ngenxa yokungcola okuphezulu kokuqukethwe, Ayikwazi ukucutshungulwa ngokuqondile futhi isetshenziswe.Ingxenye eyinhloko yomhlaba we-diatomaceous njengesithwali yi-SiO2.Isibonelo, ingxenye esebenzayo ye-industrial vanadium catalyst yi-V2O5, i-co catalyst i-alkali metal sulfate, futhi ophethe i-diatomaceous earth ecwengisisiwe.Ukuhlola kubonise ukuthi i-SiO2 inomthelela wokuzinzisa ezingxenyeni ezisebenzayo futhi iyanda ngokunyuka kokuqukethwe kwe-K2O noma kwe-Na2O.Umsebenzi we-catalyst ubuye uhlotshaniswe nokuhlakazeka kanye nesakhiwo se-pore yomthwali.Ngemuva kokwelashwa kwe-asidi yomhlaba we-diatomaceous, okuqukethwe kokungcola kwe-oxide kuncipha, okuqukethwe kwe-SiO2 kuyanda, futhi indawo ethile yendawo kanye nevolumu ye-pore nayo iyanda.Ngakho-ke, umthelela othwala umhlaba we-diatomaceous ocolisisiwe ungcono kunowomhlaba wemvelo we-diatomaceous.

Umhlaba we-Diatomaceous uvame ukwakhiwa kusuka ezinsalela ze-silicate ngemva kokufa kwe-algae eneseli elilodwa, eyaziwa ngokuthi ama-diatoms, futhi ingqikithi yawo i-amorphous amorphous SiO2.Ama-diatom angaphila emanzini ahlanzekile namanzi anosawoti, anezinhlobo eziningi.Ngokuvamile zingahlukaniswa zibe ama-diatom "e-central order" kanye nama-diatom "okuhleleka kwezimpaphe", futhi i-oda ngalinye "linezizukulwane" eziningi eziyinkimbinkimbi.

Ingxenye eyinhloko yomhlaba we-diatomaceous wemvelo i-SiO2, enekhwalithi ephezulu enombala omhlophe kanye nokuqukethwe kwe-SiO2 kuvame ukweqa ama-70%.I-diatom eyodwa ayinambala futhi isobala, futhi umbala womhlaba we-diatomaceous uncike kumaminerali obumba nezinto eziphilayo.Ukwakheka komhlaba we-diatomaceous kusuka emithonjeni yamaminerali ehlukene kuyahlukahluka.

I-Diatomaceous Earth, eyaziwa nangokuthi i-diatom, iyidiphozithi ye-diatom eyakhiwe ngemva kokufa kwesitshalo esisodwa esinengqamuzana kanye nesikhathi sokubeka iminyaka engaba ngu-10000 kuya ku-20000.I-Diatoms yayingezinye zezinto eziphilayo zokuqala ukuvela eMhlabeni, ezihlala emanzini olwandle noma emanzini echibi.

Lolu hlobo lomhlaba we-diatomaceous lwakhiwa ngokufakwa kwezinsalela zama-diatoms ezitshalo zasemanzini ezineseli elilodwa.Ukusebenza okuyingqayizivele kwale diatom ukuthi ingakwazi ukumunca i-silicon yamahhala emanzini ukuze yakhe amathambo ayo.Lapho ukuphila kwayo kuphela, ibeka futhi yakhe idiphozithi yomhlaba e-diatomaceous ngaphansi kwezimo ezithile zokuma komhlaba.Inezici ezithile eziyingqayizivele, ezifana ne-porosity, ukugxila okuphansi, indawo enkulu ethize, ukungezwani okuhlobene, nokuzinza kwamakhemikhali.Ngemuva kokushintsha usayizi wezinhlayiyana zokusabalalisa kanye nezakhiwo zomhlabathi wokuqala ngokusebenzisa i-procizinqubo zokuhlola ezifana nokuchotshozwa, ukuhlunga, ukubala, ukuhlukaniswa kokugeleza komoya, kanye nokususwa kokungcola, kungafanelekela izidingo ezihlukahlukene zezimboni ezifana nezingubo zokumboza nezithasiselo zikapende.
