Diatomaceous lapansi ndi mtundu wa miyala ya siliceous yomwe imagawidwa m'maiko monga China, United States, Japan, Denmark, France, Romania, etc. Ndi thanthwe la biogenic siliceous Sedimentary, makamaka lopangidwa ndi zotsalira za diatoms zakale.

Muli pang'ono Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, ndi organic matter.SiO2 nthawi zambiri imakhala yopitilira 80%, yokhala ndi 94%.Osayidi wachitsulo wapadziko lapansi wapamwamba kwambiri wa diatomaceous nthawi zambiri amakhala 1-1.5%, ndipo aluminium oxide imakhala 3-6%.The mchere zikuchokera diatomite makamaka Opal ndi mitundu yake, kutsatiridwa ndi dongo mchere hydromica, Kaolinite ndi mchere zinyalala.Zinyalala zamchere zimaphatikizapo quartz, feldspar, Biotite ndi organic matter.

Dziko la Diatomaceous limapangidwa ndi amorphous SiO2 ndipo lili ndi zochepa za Fe2O3, CaO, MgO, Al2O3, ndi zonyansa zakuthupi.Dziko la Diatomaceous nthawi zambiri limakhala lachikasu kapena lotuwa pang'ono, lofewa, lonyezimira, komanso lopepuka.Amagwiritsidwa ntchito kwambiri m'makampani ngati zida zotchinjiriza, zosefera, zodzaza, zopera, zopangira magalasi amadzi, zopangira ma decolorizing, zida zosefera za diatomaceous earth, zonyamulira zonyamula, etc.

Ubwino wogwiritsa ntchito nthaka ya diatomaceous: pH yosalowerera, yopanda poizoni, kuyimitsidwa kwabwino, magwiridwe antchito amphamvu, kachulukidwe kachulukidwe, mayamwidwe amafuta 115%, fineness kuyambira 325 mesh mpaka 500 mesh, kusakanikirana bwino, kusatsekeka kwa makina aulimi. mapaipi akagwiritsidwa ntchito, amatha kunyowetsa nthaka, kumasula nthaka yabwino, kukulitsa nthawi ya feteleza yabwino, ndikulimbikitsa kukula kwa mbewu.Makampani opanga feteleza: Wophatikiza feteleza wa mbewu zosiyanasiyana monga zipatso, masamba, maluwa ndi mbewu.Ubwino wogwiritsa ntchito nthaka ya diatomaceous: nthaka ya diatomaceous iyenera kugwiritsidwa ntchito ngati chowonjezera mu simenti.Zopangira zowonjezera za Diatomaceous Earth zimakhala ndi porosity yayikulu, kuyamwa mwamphamvu, kukhazikika kwa mankhwala, kukana kuvala, kukana kutentha, etc. Zitha kupereka magwiridwe antchito apamwamba kwambiri, kugwirizanitsa, kukhuthala, komanso kumamatira bwino kwa zokutira.Chifukwa cha kuchuluka kwake kwa pore, imatha kufupikitsa nthawi yowuma ya zokutira.Zingathenso kuchepetsa kuchuluka kwa utomoni wogwiritsidwa ntchito ndi kuchepetsa ndalama.Chogulitsachi chimaonedwa kuti ndi chokongoletsera bwino cha matte chokhala ndi mtengo wabwino, ndipo chasankhidwa kukhala chopangidwa ndi opanga ambiri akuluakulu apadziko lonse, omwe amagwiritsidwa ntchito kwambiri mumatope a diatomaceous opangidwa ndi madzi.
