Umhlaba we-Diatomaceous luhlobo lwamatye e-siliceous asasazwa kakhulu kumazwe anje nge China, eUnited States, eJapan, eDenmark, eFrance, eRomania, njl.Ukubunjwa kwayo kweekhemikhali ikakhulu yiSiO2, enokuthi imelwe yiSiO2 · nH2O, kunye nokwakhiwa kwayo kwamaminerali yi-opal kunye neentlobo zayo.Oovimba bomhlaba we-diatomaceous e-China zizitoni ezizigidi ezingama-320, kunye nokugcinwa okulindelweyo kweetoni ezingaphezulu kwe-2 yeebhiliyoni, ingakumbi eMpuma China nakuMntla-mpuma weTshayina.Phakathi kwabo, iJilin (i-54.8%, kunye neSixeko saseLinjiang kwiPhondo laseJilin ithatha indawo yokugcina ubungqina bokuqala e-Asiya), iZhejiang, iYunnan, iShandong, iSichuan, kunye namanye amaphondo anosasazo olubanzi, kodwa umhlaba okumgangatho ophezulu ugxininiswe kuphela kwi-intanethi. Intaba yaseChangbai yaseJilin, kunye nezinye iidiphozithi zamaminerali zibakala 3-4 lomhlaba.Ngenxa yokungacoceki okuphezulu komxholo, Ayinakwenziwa ngokuthe ngqo kwaye isetyenziswe.Inxalenye ephambili yomhlaba we-diatomaceous njengomthwali yiSiO2.Ngokomzekelo, icandelo elisebenzayo le-industrial vanadium catalyst yi-V2O5, i-co catalyst yi-alkali metal sulfate, kwaye umthwali uhlanjululwe umhlaba we-diatomaceous.Iimvavanyo zibonise ukuba i-SiO2 inefuthe lokuzinzisa kumacandelo asebenzayo kwaye yanda ngokunyuka kwe-K2O okanye umxholo we-Na2O.Umsebenzi we-catalyst unxulumene nokusabalalisa kunye nesakhiwo se-pore somthwali.Emva kokunyangwa kwe-asidi yomhlaba we-diatomaceous, umxholo wokungcola kwe-oxide uyancipha, umxholo we-SiO2 uyanda, kwaye indawo ethile yendawo kunye ne-pore volume iyanda.Ke ngoko, isiphumo somthwali womhlaba we-diatomaceous osulungekileyo ungcono kunomhlaba wendalo we-diatomaceous.

Umhlaba weDiatomaceous usenziwa ngokubanzi kwintsalela ye-silicate emva kokufa kwe-algae eneseli enye, eyaziwa njenge-diatoms, kwaye isiseko sayo yi-amorphous amorphous SiO2.Iidiatoms zinokuphila kumanzi amatsha kunye netyuwa, kunye neentlobo ezininzi.Zinokwahlulwa ngokubanzi zibe zii-diatom “ze-central order” kunye ne-“feathered order” diatom, kwaye iodolo nganye inee-“genera” ezininzi ezintsokothileyo.

Inxalenye ephambili yomhlaba we-diatomaceous wendalo yi-SiO2, enekhwalithi ephezulu enombala omhlophe kunye nomxholo we-SiO2 uhlala udlula i-70%.I-diatom enye ayinambala kwaye iyabonakala, kwaye umbala we-diatomaceous umhlaba uxhomekeke kwiiminerali zodongwe kunye ne-organic matter.Ukubunjwa komhlaba we-diatomaceous ukusuka kwimithombo eyahlukeneyo yamaminerali kuyahluka.

Umhlaba we-Diatomaceous, okwaziwa ngokuba yi-diatom, yidiphozithi ye-diatom eyenziwe emva kokusweleka kwesityalo esineseli enye kunye nexesha lokubekwa elimalunga ne-10000 ukuya kwi-20000 yeminyaka.I-Diatoms yayiyenye yezona zinto ziqala ukuvela eMhlabeni, zihlala emanzini olwandle okanye echibini.

Olu hlobo lomhlaba we-diatomaceous lwenziwa ngokubekwa kweentsalela zeediatom zezityalo zasemanzini ezineseli enye.Ukusebenza okukhethekileyo kwale diatom kukuba inokufunxa i-silicon yasimahla emanzini ukwenza amathambo ayo.Xa ubomi bayo buphela, ibeka kwaye yenze iidiphozithi ze-diatomaceous zomhlaba phantsi kweemeko ezithile zejoloji.Ineempawu ezikhethekileyo, ezifana ne-porosity, i-concentration ephantsi, indawo enkulu yendawo ethile, ukunganyanzeleki, kunye nokuzinza kweekhemikhali.Emva kokutshintsha ubungakanani bamasuntswana kunye neempawu zomphezulu womhlaba wokuqala ngeprociinkqubo zokucofa ezinje ngokutyumza, ukuhlela, ukubala, ukuhlelwa kokuhamba komoya, kunye nokususwa kokungcola, inokulungela iimfuno ezahlukeneyo zemizi-mveliso ezifana neengubo kunye nezongezo zepeyinti.
