Dziko la Diatomaceous ndi mtundu wa mwala wa siliceous womwe umafalikira makamaka m'maiko monga China, United States, Japan, Denmark, France, Romania, ndi zina zotero. Ndi mwala wa siliceous Sedimentary, womwe umapangidwa makamaka ndi zotsalira za ma diatoms akale.

Muli pang'ono Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, ndi zinthu zachilengedwe. SiO2 nthawi zambiri imakhala ndi 80%, ndipo imakhala ndi 94%. Kuchuluka kwa iron oxide mu diatomaceous earth yapamwamba nthawi zambiri kumakhala 1-1.5%, ndipo kuchuluka kwa aluminiyamu oxide ndi 3-6%. Kapangidwe ka mchere wa diatomite makamaka ndi Opal ndi mitundu yake, kutsatiridwa ndi mchere wa dongo hydromica, Kaolinite ndi zinyalala za mchere. Zinyalala za mchere zimaphatikizapo quartz, feldspar, Biotite ndi zinthu zachilengedwe.

Dziko la Diatomaceous limapangidwa ndi SiO2 yopanda mawonekedwe ndipo lili ndi zinthu zochepa za Fe2O3, CaO, MgO, Al2O3, ndi zinthu zina zachilengedwe. Dziko la Diatomaceous nthawi zambiri limakhala lachikasu chopepuka kapena imvi yopepuka, lofewa, lokhala ndi mabowo, komanso lopepuka. Limagwiritsidwa ntchito kwambiri m'mafakitale ngati zinthu zotetezera kutentha, zinthu zosefera, zodzaza, zinthu zopera, zinthu zopangira magalasi amadzi, zinthu zochotsera utoto, zinthu zothandizira zosefera za dziko lapansi za diatomaceous, zonyamulira zinthu zoyambitsa kutentha, ndi zina zotero.

Ubwino wogwiritsa ntchito nthaka ya diatomaceous: pH yosalowerera, yopanda poizoni, magwiridwe antchito abwino oimika, mphamvu yamphamvu yothira madzi, kuchuluka kwa mafuta, kuchuluka kwa mafuta komwe kumayamwa ndi 115%, kusalala kuyambira 325 mesh mpaka 500 mesh, kusakanikirana bwino, mapaipi osatsekedwa a makina a ulimi akagwiritsidwa ntchito, amatha kukhala ndi gawo lonyowetsa nthaka, kumasula nthaka, kuwonjezera nthawi yogwira ntchito ya feteleza, ndikulimbikitsa kukula kwa mbewu. Makampani opanga feteleza: Feteleza wophatikizana wa mbewu zosiyanasiyana monga zipatso, ndiwo zamasamba, maluwa ndi zomera. Ubwino wogwiritsa ntchito nthaka ya diatomaceous: nthaka ya diatomaceous iyenera kugwiritsidwa ntchito ngati chowonjezera mu simenti. Zinthu zowonjezera zophimba nthaka ya diatomaceous zimakhala ndi mawonekedwe a porosity yayikulu, kuyamwa mwamphamvu, mphamvu zokhazikika za mankhwala, kukana kukalamba, kukana kutentha, ndi zina zotero. Zitha kupereka magwiridwe antchito abwino kwambiri pamwamba, kuyanjana, kukhuthala, komanso kumamatira bwino pazophimba. Chifukwa cha kuchuluka kwa ma pore ake ambiri, zimatha kufupikitsa nthawi youma ya chophimbacho. Zingathenso kuchepetsa kuchuluka kwa utomoni womwe umagwiritsidwa ntchito ndikuchepetsa ndalama. Chogulitsachi chimaonedwa kuti ndi chinthu chopangidwa bwino chopaka utoto wopepuka komanso chotsika mtengo, ndipo chatchulidwa kuti ndi chinthu chopangidwa ndi opanga ambiri opanga utoto padziko lonse lapansi, omwe amagwiritsidwa ntchito kwambiri mu matope a diatomaceous ochokera m'madzi.
