Kev ntim khoom ntawm diatom av nkos hauv khw feem ntau qhia cov lus "tsis yog-calcined diatomite" ntawm cov khoom siv raw. Dab tsi yog qhov txawv ntawm non-calcined diatomite thiab calcined diatomite? Dab tsi yog qhov zoo ntawm non-calcined diatomaceous ntiaj teb? Ob qho tib si calcination thiab tsis yog calcination yog cov txheej txheem ntawm purification ntawm diatomaceous ntiaj teb. Diatomaceous lub ntiaj teb ore muaj ntau yam impurities, yog li cov txheej txheem yuav tsum tau siv los ua kom huv. Non-calcined yog hais txog lub ntiaj teb diatomaceous uas tsis tau calcined ntawm qhov kub thiab txias. Nws tseem hu ua dej-ntxuav diatomaceous ntiaj teb. Nws txawv ntawm flux-calcined diatomaceous ntiaj teb. Nws yog ntxuav thiab dispersed, sieved, supergravity field laminar flow centrifugal beneficiation, qhuav classification, thiab lwm yam. Lub refined diatomaceous lub ntiaj teb no tau los ntawm cov txheej txheem tau zoo txheeb thiab tshem tawm cov quartz, feldspar minerals, av nplaum thiab ib co organic teeb meem nyob rau hauv lub qub diatomite ore, thiab muaj peev xwm kom meej categorize lub ntiaj teb no nyob rau hauv lub diatomite ore. Kev ua haujlwm ntawm lub ntiaj teb diatomaceous suav nrog thaj chaw loj dua, qhov porosity dua, qhov pore loj dua, qhov pore me me, thiab muaj zog adsorption thiab av noo tswj peev xwm.

Raws li kev sib piv ntawm kev nqus dej noo ntawm ob lub diatomites nyob rau hauv tib qhov chaw tau los ntawm kev tshawb fawb hauv chav kuaj, nws yog qhov pom tseeb tias qhov muaj peev xwm nqus dej noo ntawm cov diatomite uas tsis yog calcined yog ob peb zaug ntau dua li ntawm calcined diatomite. Kev ua haujlwm ntawm diatomite yuav cuam tshuam rau lub peev xwm ntawm diatom av nkos khoom los ntes cov teeb meem molecules xws li formaldehyde uas tsis pub dawb hauv huab cua. Kev siv cov diatomite uas tsis yog-calcined tuaj yeem ua rau kom muaj qhov ua tau zoo ntawm cov av nkos diatom ntau zaus, txawm tias kaum zaug saum toj no, raws li ntau qhov kev ntsuam xyuas ntawm Hongyi non-calcined diatom av nkos cov khoom lag luam los ntawm cov koom haum cuam tshuam, formaldehyde purification kev ua tau zoo mus txog 96%, 95%, 94%, thiab 92% raws li tag nrho, thiab cov txiaj ntsig tau dhau los ntawm 90%. Nws tsis yog qhov nyuaj kom pom tias kev txhim kho kev ua haujlwm ntawm lub ntiaj teb uas tsis yog calcined diatomaceous rau diatom av nkos yog qhov pom tseeb.
