Rau kev tiv thaiv ib puag ncig, magnesium chloride yog siv los ua cov dej lim dej los kho cov dej khib nyiab, thiab kuv ntseeg tias ntau tus neeg siv khoom paub nws. Tus neeg sawv cev lim dej siv polyaluminum chloride, polyferric chloride, polyacrylamide thiab magnesium chloride ua cov khoom siv raw, ntxiv ib feem ntawm cov neeg sawv cev fluorescent whitening thiab sib tov sib npaug rau hauv cov ntaub ntawv granular, thiab tom qab ntawd nqa tawm ntau qhov hnyav ntim. Cov dej zoo, lub sijhawm luv luv, tsawg dua koob tshuaj, yooj yim decomposition, tsis muaj tshuaj lom seem, tsis muaj kev ua qias tuaj thib ob, tshem tawm SS (cov khoom seem), CODcr (tshuaj oxygen thov), BOD5 (biochemical oxygen thov) tag nrho nitrogen thiab tag nrho phosphorus yog qhov pom tseeb, ua Nws muab lub hauv paus zoo rau cov nroj tsuag lim dej thiab dej haus huv hauv ntau qhov chaw.
Kev Taw Qhia Txog Magnesium Chloride:
Lub Npe Tshuaj: Magnesium Chloride (MgCl2) Kev Piav Qhia Txog Tshuaj: Lub npe lus Askiv yog magnesium chloride. Cov mis tshuaj MgCl2 yog tsim los ntawm 74.54% chlorine thiab 25.48% magnesium, nrog rau qhov hnyav molecular ntawm 95.21. Cov siv lead ua hexagonal tsis muaj xim. Qhov ceev 2.316-2.33 grams / cubic centimeter. Melting point 714 ℃. Boiling point 1412 ℃. Feem ntau muaj rau lub molecule ntawm cov dej siv lead ua, uas yog MgCl2 • 6H2O, uas yooj yim rau deliquescence, thiab yuav poob dej siv lead ua vim huab cua hauv huab cua qhuav. Nws yog ib qho siv lead ua monoclinic nrog saj ntsev thiab qee qhov corrosiveness. Nws qhov ceev yog 1.569 g / cm3, melting point yog 116-118 ℃, thiab nws decomposes tib lub sijhawm.
Cov duab ntawm magnesium chloride: feem ntau yog flake, block, crystal, granule thiab hmoov. Cov ntsiab lus yog li 46% magnesium chloride hexahydrate, thiab 99% yog anhydrous magnesium chloride. Cov khoom siv tshuaj lom neeg thiab lub cev ntawm magnesium chloride: soluble hauv dej thiab ethanol. Cov cim qhia txog kev hnov: dawb siv lead ua, columnar lossis koob zoo li, nrog rau saj iab. Cov mis tshuaj MgCl2, siv lead ua tsis muaj xim, yooj yim soluble hauv dej, nrog rau saj iab thiab ntsev. Feem ntau muaj 6 dej siv lead ua, qhov ceev ntawm MgCl2 • 6H2O yog 1.56g / cm3, qhov chaw yaj yog 118 ℃, thiab nws lwj tib lub sijhawm. Magnesium chloride yog cov khoom siv raw rau electrolytic smelting ntawm magnesium hlau thaum cua sov, thiab nws feem ntau yog los ntawm iab ntawm lub hnub-qhuav hiav txwv ntsev.
