Diatomiteluhlobo lwelitye le-siliceous, elisasazeke kakhulu eTshayina, eUnited States, eDenmark, eFransi, eRomania nakwamanye amazwe. Luhlobo lwe-biogenic siliceous accumulation rock, equlunqwe ikakhulu ziintsalela zediatom zakudala. Ukubunjwa kwayo kweekhemikhali ikakhulu yiSiO2, enokuthi imelwe yiSiO2 · nH2O, kunye ne-mineral composition i-opal kunye neentlobo zayo.

I-China ine-320 yezigidi zeetoniumhlaba we-diatomaceousoovimba kunye neetoni ezingaphezulu kwe-2 yeebhiliyoni zoovimba abalindelekileyo, abagxile ikakhulu eMpuma China nakuMntla-mpuma weTshayina. Phakathi kwabo, uluhlu likhulu ngokwentelekiso, kwaye iJilin inoovimba ngaphezulu (54.8%, apho oovimba engqiniweyo yeSixeko Linjiang, akhawunti Jilin kwiPhondo Asia.), Zhejiang, Yunnan, Shandong, Sichuan kunye namanye amaphondo, nangona isasazwe ngokubanzi, kodwa umhlaba okumgangatho ophezulu kuphela zigxininiswe kwi Changbai ummandla weNtaba yezinye izimbiwa idiphozithi grade 3, kunye neendawo ezininzi zeediphozithi zeJilin ze-3. Ngenxa yomxholo wokungcola okuphezulu, azikwazi ukucutshungulwa ngokuthe ngqo kwaye zisetyenziswe. Ukwakhiwa kweekhemikhali ze-diatomite ikakhulu yi-SiO2, equkethe inani elincinci le-Al2O3, Fe2O3, CaO, MgO, njl. kunye ne-organic matter. Iqulethe ixabiso elincinci le-Al2O3, i-Fe2O3, i-CaO, i-MgO, i-K2O, i-Na2O, i-P2O5 kunye ne-organic matter. I-SiO2 idla ngokubala ngaphezu kwe-80%, ukuya kuma-94%. Umxholo we-iron oxide womgangatho ophezulu we-diatomaceous earth ngokuqhelekileyo ngu-1 ~ 1.5%, kwaye umxholo we-alumina ngu-3 ~ 6%. Ukubunjwa kwamaminerali e-diatomite ikakhulu i-opal kunye neentlobo zayo, ezilandelwa ngamaminerali odongwe-i-hydromica, i-kaolinite kunye ne-mineral detritus. I-Mineral debris ibandakanya i-quartz, i-feldspar, i-biotite kunye ne-organic matter. Isiqulatho se-organic sisukela kumanani omkhondo ukuya ngaphezulu kwe-30%. Umbala womhlaba we-diatomaceous umhlophe, umhlophe-mhlophe, ungwevu kunye nokukhanya kwe-gray-brown, njl njl. Uneempawu ze-fineness, looseness, ubunzima obulula, i-porosity, ukufunxa kwamanzi kunye nokungena okunamandla. Uninzi lwe-silica ye-diatomite ayinayo i-crystalline, kwaye umxholo we-asilicic acid e-soluble kwi-alkali yi-50 ~ 80%. I-Amorphous SiO2 iba yikristale xa ishushu kwi-800 ~ 1000 ° C, kwaye i-asilicic acid e-soluble kwi-alkali ingancitshiswa ibe yi-20 ~ 30%.

Umhlaba weDiatomaceousayinayo ityhefu, kulula ukwahlula ekutyeni, kwaye ingasetyenziswa kwakhona emva kokwahlukana. Iqatshelwe ziingcali ezininzi zolawulo lwezinambuzane njengento ebulala izinambuzane. Isizathu sokuba umhlaba we-diatomaceous unokuthintela izitshabalalisi kukuba xa izinambuzane zikhasa ekudleni okuxutywe nomhlaba we-diatomaceous, umhlaba we-diatomaceous uya kubambelela kumzimba wezinambuzane, utshabalalise i-waxy layer ye-epidermis yezinambuzane kunye nezinye izakhiwo ezingenamanzi, kwaye zibangele umzimba wezinambuzane. Ukuphelelwa ngamanzi kukhokelela ekufeni. Umhlaba we-Diatomaceous kunye nencindi zawo zinokusetyenziswa njengezitshabalalisi kunye nemichiza yokutshabalalisa ukhula kwiifama zeziqhamo. Amasuntswana omhlaba eDiatomaceous angasasazwa emoyeni okanye angcwatywe emhlabeni ukuze adsorb kwaye abulale ezinye izinambuzane. Umhlaba we-Diatomaceous unokusetyenziswa njengomphathi ogqwesileyo kunye ne-ejenti yokwambathisa kwizichumisi zekhemikhali. Iimicropores ezikumphezulu womhlaba wediatomaceous zinokufunxa ngokulinganayo kwaye zisonge izichumisi zekhemikhali ukunqanda ukupakishwa okuvulekileyo kwexesha elide kunye nokufunxa ukufuma kunye nokuhlangana. Iqulethe 60-80% diatom. Isichumisi esitsha se-biochemical enobume bendalo kunye nomhlaba kunye nenani elincinci le-microbial flora linokuphucula umsebenzi wokuzivikela wesityalo ngokwawo, ukukhuthaza ukukhula kwezityalo, kunye nokuphucula umhlaba ngokwawo ukufezekisa injongo yokunciphisa inani lezichumisi eziqhelekileyo kunye ne-pesticides nge-30-60% ngexesha lokukhula kwezityalo.
