Dziko la Diatomaceous, lomwe limadziwika kuti ufa wamapiri, ufa wamafuta kapena radiolaria ufa, ndi mwala wopangidwa ndi siliceous sedimentary thanthwe, makamaka wopangidwa ndi mabwinja a siliceous a diatoms ndi tizilombo tating'onoting'ono. Pali zomasulira zambiri za Chingerezi, zomwe zimawonekera m'manyuzipepala ndi m'mabuku: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
Diatomite ndi mwala wonyezimira wonyezimira wonyezimira womwe umapangidwa makamaka ndi mabwinja a siliceous a diatoms. Ndi thanthwe lokhala ndi porous kwambiri ndi kukula kwa tinthu tating'ono komanso mphamvu yokoka yochepa. Izi zimapangitsa kuti zikhale zothandiza ngati zosefera, zoyamwitsa, komanso zopepuka zodzaza mphira, utoto, ndi mapulasitiki. Diatomite ikaphwanyidwa kukhala ufa, nthawi zambiri imatchedwa "diatomaceous earth," kapena DE Diatomite Yochokera ku zotsalira zazing'ono zazing'ono zam'madzi zam'madzi kapena ndere zamadzi amchere, diatomite ndi mchere wochitika mwachilengedwe, wosunthika womwe umagwiritsidwa ntchito mosiyanasiyana kuchokera ku zodzoladzola mpaka kusefera. .
Chigawo chachikulu cha mankhwala a dziko la diatomaceous ndi silicate. Zomwe zili mu SiO2 ndi chimodzi mwa zizindikiro za zomwe zili mu diatomite ore, ndipo SiO2 yapamwamba ndi yabwino. Dziko lapansi la Diatomaceous lili ndi madzi 1% ~ 5%, ndipo kutentha kwa madzi a colloidal ndi 110 ~ 250 °C.
Kugwiritsa Ntchito Diatomite ndi Diatomaceous Earth
Diatomite imagwiritsidwa ntchito ngati chowonjezera popanga simenti ya portland. Diatomite yapamwamba imakhala ndi silika yopitilira 80%, ndipo imawonjezeredwa popanga simenti kuti ilimbikitse zomwe zili mu silika. Diatomite yolunjika kuchokera ku mgodi imaphwanyidwa ndikuphatikizidwa ndi miyala ya laimu, shale, kapena zinthu zina zomwe zimagwiritsidwa ntchito popanga simenti.
Ntchito zinayi zazikulu za diatomite ku United States mu 2017 zinali kusefera (50%), kuphatikiza kuwala (30%), fillers (15%), ndi absorbents (5%). Zida za diatomite zomwe zimapangitsa kuti zikhale zothandiza pamapulogalamuwa zalembedwa pansipa.
- Kukula kwa tinthu kakang'ono
- Mkulu porosity
- Malo apamwamba
- Zomwe zili mkati mwa siliceous
- Mphamvu yokoka yotsika
