Nyika yeDiatomaceous imhando yedombo resiliceous rinonyanya kupararira munyika dzakadai seChina, United States, Japan, Denmark, France, Romania, nezvimwewo. Idombo reSedimentary resiliceous, rinonyanya kuumbwa nemasara ediatoms ekare.

Ine huwandu hushoma hweAl2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, uye organic matter. SiO2 inowanzoita zvinopfuura 80%, ine huwandu hwakanyanya hwe94%. Huremu hweiron oxide mu diatomaceous earth yemhando yepamusoro hunowanzova 1-1.5%, uye huwandu hwealuminium oxide huri 3-6%. Musanganiswa wemineral wediatomite unonyanya kuve Opal nemarudzi ayo, uchiteverwa nemamineral evhu hydromica, Kaolinite nemamineral debris. Mamineral debris anosanganisira quartz, feldspar, Biotite uye organic matter.

Ivhu reDiatomaceous rinoumbwa neSiO2 isina chimiro uye rine huwandu hushoma hweFe2O3, CaO, MgO, Al2O3, uye tsvina yeorganic. Ivhu reDiatomaceous rinowanzova yero yakajeka kana grey rakapfava, rakapfava, rine maburi, uye rakareruka. Rinoshandiswa zvakanyanya mumaindasitiri sezvinhu zvinodzivirira kupisa, zvinhu zvekusefa, zvinozadza, zvinhu zvekukuya, zvinhu zvegirazi remvura, zvinhu zvinobvisa ruvara, zvinhu zvinobatsira pakusefa kwediatomaceous, zvinhu zvinotakura catalyst, nezvimwewo.

Zvakanakira kushandisa ivhu rediatomaceous: pH isina chepfu, haina chepfu, inoshanda zvakanaka pakumisa, inoshanda zvakanyanya pakunyungudutsa, huwandu hwechiedza, mwero wekunyudzwa kwemafuta we115%, kupfava kubva pa325 mesh kusvika pa500 mesh, kusanganiswa kwakanaka, kusavharika kwemapaipi emuchina wekurima panguva yekushandiswa, zvinogona kuita basa rekunyorovesa ivhu, kusunungura kunaka kwevhu, kuwedzera nguva inoshanda yefetereza, uye kukurudzira kukura kwezvirimwa. Indasitiri yefetereza yakasanganiswa: Fetereza yakasanganiswa yezvirimwa zvakasiyana-siyana zvakaita semichero, miriwo, maruva nemiti. Zvakanakira kushandisa ivhu rediatomaceous: ivhu rediatomaceous rinofanira kushandiswa sechinowedzera mu simende. Zvigadzirwa zvekuwedzera zveDiatomaceous earth coating zvine hunhu hwe porosity yakakwira, kunyudzwa kwakasimba, hunhu hwakagadzikana hwemakemikari, kuramba kupfeka, kuramba kupisa, nezvimwewo. Zvinogona kupa kushanda kwakanaka kwepamusoro, kukwirira, kusimba, uye kunatsiridza kunamira kwepente. Nekuda kwehuwandu hwayo hukuru hwemaburi, inogona kupfupisa nguva yekuoma kwepente. Inogona zvakare kuderedza huwandu hwe resin inoshandiswa uye kuderedza mitengo. Chigadzirwa ichi chinoonekwa sechigadzirwa chinoshanda zvakanaka chekudzivirira matte uye chinodhura zvakanaka, uye chakasarudzwa sechigadzirwa nevagadziri vemachira makuru epasi rose, chinoshandiswa zvakanyanya mumatope emvura ane diatomaceous.
