CAS #: 68855-54-9 (hmoov sib xyaw ua ke)
Kev Siv: Siv rau hauv kev lag luam brewing, kev lag luam dej haus, kev lag luam tshuaj, kev ua kom huv, kev ua kom qab zib, thiab kev lag luam tshuaj lom neeg.
Cov tshuaj lom neeg muaj pes tsawg leeg
Cov tshuaj lom neeg ntawm lub ntiaj teb diatomaceous yog feem ntau amorphous SiO2, uas muaj nyob rau hauv daim ntawv ntawm SiO2• nH2O. SiO2feem ntau suav txog ntau dua 80%, txog li 94%. Nws muaj me me ntawm Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, thiab cov organic teeb meem, nrog rau qee cov hlau tsis huv xws li Cr thiab Ba. Cov khoom sib xyaw thiab cov ntsiab lus ntawm cov av diatomaceous sib txawv hauv thaj chaw sib txawv.
Cov Khoom Siv Lub Cev
Lub ntiaj teb diatomaceous muaj xim xws li dawb, grey dawb, grey, lub teeb grey, lub teeb grey xim av, lub teeb daj, thiab lwm yam.; Qhov ceev: 1.9 ~ 2.3g / cm3Qhov ceev ntawm cov khoom loj 0.34 ~ 0.65g / cm3; Melting point: 1650 ℃ ~ 1750 ℃; Qhov chaw tshwj xeeb ntawm 19-65cm2/g; Qhov ntim ntawm qhov hws 0.45 ~ 0.98 cm3/g; Tus nqi nqus dej yog 2-4 npaug ntawm nws tus kheej ntim. Kev ruaj khov tshuaj lom neeg siab, tsis yaj hauv hydrochloric acid, yooj yim yaj hauv alkali, nrog ntau yam khoom zoo heev xws li kev tsis sib haum xeeb, mos, rwb thaiv suab, hnav tsis kam, thiab tiv taus kub.
Kev Txhim Kho thiab Daim Ntawv Thov
Lub ntiaj teb diatomaceous, vim nws cov khoom siv physicochemical tshwj xeeb, tau siv dav ua cov khoom pab lim dej, cov khoom ua haujlwm, cov khoom thauj catalyst, cov khoom siv tua kab thiab cov chiv chiv, cov khoom siv rwb thaiv tsev, cov khoom nqus dej, thiab cov khoom siv dawb.
Kev pab lim dej:
Diatomaceous earth siv tau ua ib yam khoom pab lim dej hauv kev lag luam khoom noj, tshuaj, thiab ib puag ncig. Piv txwv li, kev siv diatomaceous earth lim dej hauv cov txheej txheem ua cawv tuaj yeem hloov kho lub txaj lim dej tas li, lim dej sai, thiab muaj txiaj ntsig zoo; Nrog thaj chaw loj thiab muaj peev xwm nqus tau zoo, nws tuaj yeem lim cov khoom me me txij li 0.1 txog 1.0 μ m, txo cov cawv poob li ntawm 1.4%, thiab txhim kho cov xwm txheej ua haujlwm ntau lawm. Cov lim dej diatomaceous earth tuaj yeem txhim kho qhov zoo ntawm dej ntawm pas dej da dej, thiab tuaj yeem txuag dej thiab hluav taws xob hauv kev ua haujlwm thiab kev tswj hwm pas dej da dej. Qhov thib ob, diatomaceous earth kuj tau siv dav hauv cov roj noj tau, cov kua dej hauv qhov ncauj, thiab lwm yam teb.
Cov Khoom Nqus Tau:
Diatomaceous earth siv dav hauv kev kho dej khib nyiab vim nws cov khoom siv tshuaj ruaj khov, muaj peev xwm nqus tau zoo, ua haujlwm zoo thiab tsis yaj hauv cov kua qaub muaj zog. Kev kho cov av khib nyiab ua ntej siv cov txheej txheem flocculation precipitation tuaj yeem txo CODCr thiab BOD5 hauv cov av khib nyiab, tshem tawm cov pa phem xws li SS, thiab feem ntau yog siv rau cov dej khib nyiab hauv nroog, cov dej khib nyiab ua ntawv, cov dej khib nyiab luam ntawv thiab zas xim, cov dej khib nyiab tua tsiaj, cov dej khib nyiab roj, thiab cov dej khib nyiab hlau hnyav.
