Siv: Siv rau hauv kev lag luam brewing, haus dej haus, kev lag luam tshuaj, refining, qab zib refining, thiab tshuaj lom neeg kev lag luam.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm lub ntiaj teb diatomaceous feem ntau yog amorphous SiO2, uas muaj nyob rau hauv daim ntawv ntawm SiO2• nH2O.SiO2feem ntau suav nrog ntau dua 80%, mus txog 94%. Nws muaj me me ntawm Al2O3, Fe2O3, CaO, MgO, K2Aw, Na2O, P2O5, thiab organic teeb meem, nrog rau qee cov hlau impurities xws li Cr thiab Ba. Cov muaj pes tsawg leeg thiab cov ntsiab lus ntawm diatomaceous lub ntiaj teb mines sib txawv nyob rau hauv txawv cheeb tsam.
Lub cev muaj zog
Diatomaceous lub ntiaj teb muaj xim xws li dawb, grey dawb, grey, lub teeb grey, lub teeb grey xim av, lub teeb daj, thiab lwm yam.; Ceev: 1.9 ~ 2.3g / cm30.34 ~ 0.65g / cm33; Melting point: 1650 ℃ ~ 1750 ℃; Qhov tshwj xeeb thaj tsam ntawm 19-65cm2/g; Pore ntim 0.45 ~ 0.98cm3/g; Tus nqi nqus dej yog 2-4 npaug ntawm nws tus kheej ntim. Cov tshuaj lom neeg ruaj khov siab, insoluble hauv hydrochloric acid, yooj yim soluble hauv alkali, nrog ntau yam khoom zoo xws li cov txheeb ze incompressibility, softness, suab rwb thaiv tsev, hnav tsis kam, thiab kub tsis kam.
Kev txhim kho thiab kev siv
Diatomaceous lub ntiaj teb, vim nws qhov tshwj xeeb physicochemical zog, tau dav siv los ua cov khoom siv lim dej, cov khoom siv ua haujlwm, catalyst carrier, tshuaj tua kab thiab chiv, cov khoom siv rwb thaiv tsev, adsorbent, thiab cov khoom siv tshuaj dawb.
Lim pab:
Diatomaceous ntiaj teb tuaj yeem siv los ua kev lim dej hauv cov zaub mov, tshuaj, thiab kev lag luam ib puag ncig. Piv txwv li, kev siv diatomaceous lub ntiaj teb pom nyob rau hauv cov txheej txheem winemaking tuaj yeem hloov kho lub txaj lim, ceev ceev ceev, loj yield; Nrog rau thaj tsam loj thiab muaj peev xwm adsorption, nws tuaj yeem lim tawm qhov sib txawv ntawm 0.1 txog 1.0 μ m, txo qis cawv los ntawm 1.4%, thiab txhim kho kev ua haujlwm ntau lawm. Diatomaceous lub ntiaj teb lim dej tuaj yeem txhim kho cov dej zoo ntawm lub pas dej da dej circulating dej kho, thiab tuaj yeem txuag dej thiab hluav taws xob hauv kev ua haujlwm thiab kev tswj cov pas dej da dej. Qhov thib ob, lub ntiaj teb diatomaceous kuj tau siv dav hauv cov roj noj, cov kua hauv qhov ncauj, thiab lwm yam.
Adsorbent:
Diatomaceous ntiaj teb yog dav siv hauv kev kho dej khib nyiab vim nws cov khoom siv tshuaj ruaj khov, muaj peev xwm adsorption, zoo pom kev ua haujlwm thiab insolubility hauv cov kua qaub. Kev kho ua ntej ntawm cov khib nyiab pov tseg siv diatomaceous lub ntiaj teb flocculation nag lossis daus txheej txheem tuaj yeem txo qis CODCr thiab BOD5 hauv cov kua dej, tshem tawm cov pa phem xws li SS, thiab feem ntau yog siv rau hauv nroog cov dej khib nyiab, cov dej khib nyiab, luam ntawv thiab dyeing cov dej khib nyiab, slaughter wastewater, oily wastewater. , thiab hnyav hlau khib nyiab.
