Diatomaceous ntiaj teb, feem ntau hu ua roob hmoov, fossil hmoov los yog radiolaria hmoov, yog ib tug biogenic siliceous sedimentary pob zeb, feem ntau yog tsim los ntawm siliceous seem ntawm diatoms thiab lwm yam kab mob. Muaj ntau phau ntawv txhais lus Askiv, uas tshwm sim hauv cov ntawv xov xwm thiab cov ntawv xov xwm: Tripoli, Tripolite, TripoliEarth, Tripoli-Powder, Diatomite.
Diatomite yog ib lub teeb ci-xim pob zeb sedimentary uas yog tsim los ntawm cov pob txha pob txha siliceous ntawm diatoms. Nws yog ib lub pob zeb ntxeem tau heev nrog ib tug zoo particle loj thiab ib tug tsawg lub ntiajteb txawj nqus. Cov khoom no ua rau nws muaj txiaj ntsig zoo li cov khoom siv lim dej, cov khoom nqus dej, thiab ua lub teeb hnyav rau cov roj hmab, xim, thiab cov yas. Thaum diatomite raug crushed rau hauv cov hmoov, nws feem ntau hu ua "diatomaceous ntiaj teb," los yog DE Diatomite Muab tau los ntawm cov seem ntawm microscopic fossilized hiav txwv los yog dej tshiab algaes, diatomite yog ib txwm tshwm sim, ntau yam ntxhia siv nyob rau hauv array ntawm daim ntaub ntawv los ntawm cov tshuaj pleev ib ce rau pom. .
Cov tshuaj tseem ceeb ntawm lub ntiaj teb diatomaceous yog silicate. Cov ntsiab lus ntawm SiO2 yog ib qho ntawm cov ntsiab lus ntawm diatoms hauv diatomite ore, thiab siab SiO2 yog qhov zoo. Diatomaceous ntiaj teb muaj 1% ~ 5% dej, thiab dej poob kub ntawm colloidal dej yog 110 ~ 250 ° C
Kev siv Diatomite thiab Diatomaceous Earth
Diatomite feem ntau yog siv los ua ib qho ntxiv hauv kev tsim cov portland cement. High-zoo diatomite muaj ntau tshaj 80% silica, thiab nws ntxiv rau cov cement-making txheej txheem los txhawb cov silica cov ntsiab lus ntawm cov khoom. Diatomite ncaj nraim los ntawm lub mine yog crushed thiab sib tov nrog limestone, shale, los yog lwm yam khoom siv los ua cov cement.
Plaub qhov tseem ceeb ntawm kev siv diatomite hauv Tebchaws Meskas thaum xyoo 2017 yog pom (50%), lub teeb sib sau (30%), fillers (15%), thiab absorbents (5%). Cov khoom ntawm diatomite uas ua rau nws muaj txiaj ntsig hauv cov ntawv thov no tau teev tseg hauv qab no.
- Me me particle loj
- Siab porosity
- Qhov chaw siab
- Sib piv inert siliceous muaj pes tsawg leeg
- Tsawg lub ntiajteb txawj nqus
