Magnesium sulfate heptahydrate, tseem hu ua sulphobitter, iab ntsev, tshuaj ntsuab, tshuaj pleev xim dawb lossis xim tsis muaj xim, tsis muaj ntxhiab, txias thiab me ntsis ntsim. Tom qab kub decomposition, lub crystalline dej yog maj muab tshem tawm mus rau anhydre magnesium sulfate. Nws yog tsuas yog siv nyob rau hauv kev tsim cov chiv, tawv, luam ntawv thiab tawg, porcentics, porments, ntais ntawv, tawg thiab cov khoom tawg. Nws tuaj yeem siv rau luam ntawv thiab dyeing nyias paj rwb paj rwb thiab lo lo ntxhuav, ua cov khoom ntim rau cov paj ntaub, thiab siv ua cov tshuaj eploom hauv tshuaj.
Lub cev lub cev:
Cov tsos mob thiab cov khoom: belongs rau rhombic crystal system, rau plaub ceg crystal, tsis muaj xim, pob tshab, sawv lossis ntsuab iav live. Cov duab yog fibrous, acicular, granular los yog hmoov. Ntxhiab, iab saj.
Solubility: yooj yim soluble hauv dej, me ntsis soluble hauv ethanol thiab glycerol.
Tshuaj lom neeg cov khoom:
Stability: ruaj khov nyob rau hauv cov huab cua noo hauv qab 48.1 ° C. Nws yooj yim kom haum rau hauv huab cua sov thiab qhuav. Thaum nws siab tshaj 48.1 ° C, nws poob ib lub crystalline dej thiab ua cov khawv koob sulfate. Nyob rau tib lub sijhawm, cov hlau nplaum sulfate yog precipitated. Ntawm 70 ° C, nws swb 4 siv lead ua dej ntawm 100 ° Crystal dej ntawm 100 ° Crystal dej ntawm 100 ° kom rov qab dej. Nyob rau hauv cov tshuaj uas noo noo ntawm magnesium sulfate, cov dej-kerystalline nrog 1, 2, 3, 5, thiab 12 dej tuaj yeem yog CRYSTAL. Nyob rau hauv -1.8 ~ 48.18 ° Curegated queous daws, magnesium sulfate yog precipitated ntawm 48.1 txog 67.5 ° C, magnesium sulfate yog precipitated yog precipitated. Thaum nws siab dua 67.5 ° C, ib qho magnesium sulfate yog precipitated. Alien melting ntawm ° C thiab magnesium sulfate ntawm tsib lossis plaub dej sulfate tau tsim. Magnesium sulfate tau hloov mus rau hauv magnesium sulfate ntawm 106 ° C. Magnesium Sulfate tau hloov mus rau hauv ruaj khov magnesium sulfate ntawm 161 ~ 169 ℃.
Tshuaj lom: lom
PH tus nqi: 7, nruab nrab
Daim ntawv thov tseem ceeb:
1) Cov Khoom Noj Khoom Haus
Raws li cov khoom siv nyiaj pub dawb. Kuv lub teb chaws cov cai tuaj yeem siv rau cov khoom noj mis, nrog tus nqi ntawm 3 mus rau 7G / kg; Tus nqi siv hauv dej haus thiab mis haus yog 1.4 ~ 2.8g / kg; Qhov kev siv siab tshaj plaws hauv kev haus ntxhia yog 0. 0.05g / kg.
2) Kev Ua Teb
Nws feem ntau yog siv nrog calcium ntsev rau dej niam. Ntxiv rau 4.4G / 100L dej tuaj yeem nce kev tawv los ntawm 1 degree. Thaum siv, nws tuaj yeem tsim kev iab thiab ua rau muaj mob hydrogen sulfide tsw.
Siv ua lub suab nrov, cov khoom tawg, papermaking, plooj (cov quav yeeb yaj kiab, thiab tshuaj kho mob laxes, thiab lwm yam.
3) Ua liaj ua teb teb
Magnesium sulfate yog siv nyob rau hauv cov chiv hauv kev ua liaj ua teb vim tias magnesium yog ib qho ntawm chlorophyll. Cov qoob loo ntawm potted nroj tsuag lossis cov hlau nplaum feem ntau yog siv, xws li txiv lws suav, qos yaj ywm, cov qos yaj ywm muaj ntau solubility piv rau lwm cov chiv. Magnesium sulfate kuj tau siv los ua ntsev da dej.
Kev npaj txoj kev:
1) txoj kev 1:
Sulfuric acid ntxiv rau ntuj magnesium carbonate (magesesite), carbon dioxide raug tshem tawm, recryerite (KGOthstallized, ua los ntawm dej hiav txwv.
2) txoj kev 2 (Leaching txoj kev)
Tom qab lub brine yog evaporated los ntawm cov kab kev brine, ntsev kub siab yog tsim tawm, thiab nws muaj pes tsawg leeg yog MGSO4>. 30 feem pua. 35%, MGCL2 txog 7%, KCl txog 0.5%. Cov kab mob me me tuaj yeem ua kom tiav nrog mgcl2 daws ntawm 200g / l ntawm 48 ℃, nrog tsawg dua mgl daws thiab ntau mgro4 tov. Tom qab sib cais, Mghib tau ua ntej los ntawm kev txias txias thaum 10 ℃, thiab cov khoom tiav tau los ntawm theem nrab recrystallization.
3) txoj kev 3 (sulfuric acid qauv)
Hauv nruab nrab tank, cov rhombotrite tau maj mam ntxiv mus rau hauv dej thiab niam cawv, thiab tom qab ntawd neutralized nrog sulfuric acid. Cov xim hloov los ntawm lub ntiaj teb xim rau xim liab. Tus p yog tswj tau 5, thiab tus txheeb ze ceev yog 1.37 ~ 1.38 (39 ~ 40 ° yuav). Qhov kev daws teeb meem nruab nrab tau lim ntawm 80 ℃, ces pH tau kho kom haum rau 4 nrog cov sulfuric acid, tsim nyog noob muaju tau ntxiv, thiab txias rau 30 ℃ rau crystallization. Tom qab sib cais, cov khoom tiav tau qhuav ntawm 50 ~ 55 ℃, thiab leej niam cawv tau rov qab mus rau neutralization tank. Magnesium sulfate tau heptahydrate kuj tseem tuaj yeem npaj los ntawm kev tsis txaus siab ntawm kev sib cais, nag lossis daus, nws yog ua los ntawm magnesium sulfate.
Cov tshuaj tiv thaiv kev sib txig sib luag: Mgo + H2SO4 + 6h2o → mGso4S2o.
Kev tiv thaiv thauj mus los:Cov ntim yuav tsum ua tiav thaum thauj, thiab kev thauj khoom yuav tsum muaj kev nyab xeeb. Thaum lub sijhawm thauj mus los, xyuas kom meej tias lub thawv yuav tsum tsis txhob xau, vau, poob, lossis puas tsuaj. Nws yog nruj me ntsis txwv tsis pub sib xyaw nrog cov kua qaub thiab cov tshuaj uas tau pom. Thaum lub sijhawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm lub hnub kis, nag thiab kub kub. Lub tsheb yuav tsum tau huv si tom qab kev thauj mus los.
Kev ceev faj:Kaw cov haujlwm thiab ntxiv dag zog tau cua. Tus neeg teb xov tooj yuav tsum ua raws li cov kev ua haujlwm tom qab kev qhia tshwj xeeb. Nws raug nquahu kom cov neeg ua haujlwm muaj cov iav lim hiam kev nyab xeeb, hnav los tiv thaiv cov khaub ncaws ua haujlwm, thiab hnab looj tes roj hmab. Tsis txhob muaj hmoov av. Zam kev sib cuag nrog cov kua qaub. Lub teeb thiab maj mam tshem tawm cov ntim kom tiv thaiv kom txhob ntim ntawm kev puas. Nruab nrog cov khoom siv kho kom muaj dej kub ceev. Cov khoom ntim khoom yuav tsis muaj teeb meem. Thaum cov plua tshauv siab rau saum huab cua tshaj tus qauv, peb yuav tsum hnav tus kheej-augated lim plua plha. Thaum muaj kev cawm thaum muaj xwm txheej ceev lossis khiav tawm, hnav cov qhov ncauj qhov ntswg yuav tsum hnav.
Cia Kev ceev faj:Khaws cia rau hauv lub tsev rau khoom txias, ventilated warehouse. Nyob deb ntawm hluav taws thiab tshav kub. Khaws cais tawm ntawm cov kua qaub thiab tsis txhob sib xyaw. Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to.
