Diatomite (diatomaceous earth) idombo rakapfava, rakareruka resiliceous sedimentary rakaumbwa kubva mumatongo ezvinyorwa zvekare zvemadiatoms emumvura—algae ine cell imwe chete ine magoko esilica. Yakagadzirwa zvakanyanya nesilica isina kristalline (SiO₂, 80%–90%), ine alumina diki, iron oxide, uye organic matter, ine chimiro chakasiyana che microporous, porosity yakakura (kusvika 90%), nzvimbo yakakura chaiyo, kugona kwakasimba kwekunyungudika, kusagadzikana kwemakemikari, uye kuramba kupisa. Sechicherwa chisina chepfu uye chinodzivirira nharaunda, chinoshandiswa zvakanyanya mukusefa chikafu, kurapwa kwemvura, kuchengetedza nharaunda, kuvaka, uye kuzadza maindasitiri.

Diatomite isina kuchena inogadziriswa nekupwanya, kuomesa, kukuya, uye kuchenesa (kusuka, kupatsanura nemagnetic, calcination) kubvisa tsvina yevhu, quartz, uye iron. Magiredhi ekuchena kwepamusoro aneSiO₂ ≥85%, kuchena ≥85%, pasi Fe₂O₃ (<1.5%), uye saizi yezvikamu zvinodzorwa (10–200 μm), zvichiita kuti zvive nyore kusefa, kunyudza, uye kuzadza kushande zvakanaka.

Ma micropores akafanana eDiatomite (0.1–10 μm) anoita kuti ive sefa yakanaka, inobata zvidimbu zvidiki uku ichibvumira mvura kuyerera.

• Chikafu & Chinwiwa: Inojekesa doro, waini, muto, uye sirapu nekubvisa mbiriso, mabhakitiriya, nezvinhu zvakaoma zvakamiswa, ichivandudza kujeka uye kugara kwenguva refu.
• Kurapa Mvura: Inobvisa simbi dzinorema (Pb²⁺, Cd²⁺), tsvina yemuchadenga, uye hwema hunobva mumvura yakasviba yemumaindasitiri, mvura yemumaguta, uye madziva ekushambira.
• Mishonga: Inosefa mishonga inorwisa utachiona, mvura inonwiwa, uye zvigadzirwa zvemuviri kuti icheneserwe utachiona.

Maumbirwo eDiatomite ane maburi anobvumirakudzorwa kwehunyoro, kucheneswa kwemhepo, kudzivirira ruzha, uye kuchengetedza kupisa.

• Madhaka eDiatom (Matanda Ekudzivirira Madziro): Inonwisa/inoburitsa hunyoro kudzivirira chakuvhuvhu, inonwisa formaldehyde, benzene, uye VOCs, uye inoderedza ruzha—inozivikanwa se "madziro anofema".
• Kudzivirira Kureruka: Inoshandiswa muzvidhinha zvinopisa, mabhodhi ekudzivirira kupisa, uye machira anodzivirira kupisa zvakanyanya (kusvika 1400°C) uye mafambiro ekupisa akaderera.

Semuchina wekusimbisa, inowedzera hunhu hwemakanika uye kugona kushandiswa kwemapolymers.

• Pendi & Mapendi: Inovandudza kugara kwenguva refu, kuramba kukwenya, uye kupera kwemavara matema; inoderedza kugadzikana.
• Rabha & Mapurasitiki: Inowedzera kuomarara, kuramba kupisa, uye kugadzikana kwezvikamu; inoderedza mutengo.
• Kurima: Inonwisa mishonga yezvipembenene/fetereza kuti ibude zvishoma nezvishoma; inoshanda semushonga wezvipembenene wechisikigo nekukuvadza mapundu ezvipembenene.

Tinopa diatomite isina kubikwa, yakagezwa, yakakangwa, uye yakagadziriswa pamusoro ine saizi dzezvimedu zvinogadziriswa uye magiredhi ekuchena. Zvigadzirwa zvinoenderana neISO 9001, REACH, uye mwero wekuchengetedza chikafu, zvichishandira maindasitiri epasi rose ekusefa, ezvakatipoteredza, uye ekuvaka. Samples dzemahara uye rutsigiro rwehunyanzvi zviripo.
