Kev taw qhia luv luv:
Ferrous sulfate heptahydrate, feem ntau hu ua ntsuab alum, yog ib qho inorganic compound nrog cov mis FeSO4·7H2O.Feem ntau yog siv rau hauv kev tsim cov hlau ntsev, number case, hlau nplaum hlau oxide, dej purification tus neeg saib xyuas, tshuaj tua kab mob, hlau catalyst;Nws yog siv los ua coal dye, tanning agent, bleaching agent, wood preservative and compound fertilizer additive, and processing ferrous sulfate monohydrate.Cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm ferrous sulfate heptahydrate yog qhia nyob rau hauv daim ntawv no.
Xwm
Ferrous sulfate heptahydrate yog cov siv lead ua xiav xiav nrog qhov zoo sib hloov siv lead ua qhov system thiab cov qauv hexagonal ze-packed.
Ferrous sulfate heptahydrate yog ib qho yooj yim kom poob dej siv lead ua nyob rau hauv cov huab cua thiab ua anhydrous ferrous sulfate, uas muaj zog reducibility thiab oxidation.
Nws cov tshuaj aqueous yog acidic vim nws decomposes hauv dej los tsim sulfuric acid thiab ferrous ions.
Ferrous sulfate heptahydrate muaj qhov ntom ntawm 1.897g / cm3, melting point ntawm 64 ° C thiab boiling point ntawm 300 ° C.
Nws thermal stability tsis zoo, thiab nws yooj yim rau decompose ntawm qhov kub thiab txias los tsim cov pa phem xws li sulfur dioxide thiab sulfur trioxide.
Daim ntawv thov
Ferrous sulfate heptahydrate yog dav siv hauv kev lag luam.
Ua ntej, nws yog ib qho tseem ceeb ntawm cov hlau, uas tuaj yeem siv los npaj lwm cov hlau sib txuas, xws li ferrous oxide, ferrous hydroxide, ferrous chloride, thiab lwm yam.
Qhov thib ob, nws tuaj yeem siv los npaj cov tshuaj xws li roj teeb, dyes, catalysts, thiab tshuaj tua kab.
Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv kev kho dej khib nyiab, desulfurization, phosphate fertilizer npaj thiab lwm yam.
Qhov tseem ceeb ntawm ferrous sulfate heptahydrate yog qhov tseeb ntawm nws tus kheej, thiab nws muaj ntau yam kev siv hauv kev tsim khoom.
Txoj kev npaj
Muaj ntau txoj hauv kev rau kev npaj ntawm ferrous sulfate heptahydrate, thiab cov txheej txheem ntau yog raws li hauv qab no:
1. Kev npaj ntawm sulfuric acid thiab ferrous hmoov.
2. Kev npaj ntawm sulfuric acid thiab ferrous ingot cov tshuaj tiv thaiv.
3. Kev npaj ntawm sulfuric acid thiab ferrous ammonia.
Nws yuav tsum tau muab sau tseg tias cov tshuaj tiv thaiv tej yam kev mob yuav tsum tau nruj me ntsis tswj nyob rau hauv lub txheej txheem ntawm kev npaj kom tsis txhob muaj teeb meem gases thiab tsis tsim nyog poob.
Kev ruaj ntseg
Ferrous sulfate heptahydrate muaj qee qhov kev pheej hmoo, yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus hauv qab no:
1. Ferrous sulfate heptahydrate yog ib qho tshuaj lom thiab yuav tsum tsis txhob kov ncaj qha.Kev nqus pa, noj thiab kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav tsum zam.
2. Nyob rau hauv kev npaj thiab siv ferrous sulfate heptahydrate, yuav tsum tau saib xyuas kom tsis txhob muaj teeb meem gases thiab hluav taws kub thiab tawg txaus ntshai.
3. Thaum lub sijhawm khaws cia thiab kev thauj mus los, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog cov tshuaj xws li oxidants, acids thiab alkalis kom tsis txhob muaj kev cuam tshuam thiab kev raug mob.
Cov ntsiab lus
Hauv kev xaus, ferrous sulfate heptahydrate yog ib qho tseem ceeb inorganic compound thiab muaj ntau yam kev siv.
Hauv kev tsim khoom lag luam thiab chaw kuaj mob, yuav tsum tau saib xyuas rau nws qhov kev pheej hmoo, thiab kev ntsuas tsim nyog yuav tsum tau coj mus rau kev khaws cia, kev thauj mus los thiab siv los ua kom muaj kev nyab xeeb ntawm tus kheej thiab kev tiv thaiv ib puag ncig.
Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev txuag cov peev txheej hauv cov txheej txheem ntawm kev siv kom tsis txhob pov tseg thiab muaj kuab paug.
