Ferrous Sulfate Heptahydrate

Kev Taw Qhia Luv Luv：

Ferrous sulfate heptahydrate, feem ntau hu ua alum ntsuab, yog ib qho inorganic compound nrog cov mis FeSO4 · 7H2O. Feem ntau siv rau hauv kev tsim cov ntsev hlau, kua mem, hlau oxide sib nqus, tus neeg sawv cev ntxuav dej, tshuaj tua kab mob, catalyst hlau; Nws yog siv los ua cov xim thee, tus neeg sawv cev tanning, tus neeg sawv cev bleaching, ntoo preservative thiab compound fertilizer additive, thiab ua ferrous sulfate monohydrate. Cov yam ntxwv, kev siv, kev npaj thiab kev nyab xeeb ntawm ferrous sulfate heptahydrate tau qhia nyob rau hauv daim ntawv no.

Xwm

Ferrous sulfate heptahydrate yog ib qho siv lead ua xiav nrog lub kaw lus siv lead ua zoo sib hloov thiab ib qho qauv kaw hexagonal.

Ferrous sulfate heptahydrate yooj yim poob dej siv lead ua rau huab cua thiab dhau los ua anhydrous ferrous sulfate, uas muaj zog reducibility thiab oxidation.

Nws cov kua dej yog acidic vim nws decomposes hauv dej los tsim cov sulfuric acid thiab ferrous ions.

Ferrous sulfate heptahydrate muaj qhov ceev ntawm 1.897g / cm3, lub ntsiab lus yaj ntawm 64 ° C thiab lub ntsiab lus kub ntawm 300 ° C.

Nws qhov kev ruaj khov thermal tsis zoo, thiab nws yooj yim rau decompose ntawm qhov kub siab los tsim cov pa phem xws li sulfur dioxide thiab sulfur trioxide.

Daim Ntawv Thov

Ferrous sulfate heptahydrate yog siv dav 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 xyaw, 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, cov xim pleev xim, cov tshuaj catalysts, thiab cov tshuaj tua kab.

Tsis tas li ntawd xwb, nws kuj siv tau rau hauv kev kho dej khib nyiab, desulfurization, phosphate fertilizer preparation thiab lwm yam.

Qhov tseem ceeb ntawm ferrous sulfate heptahydrate yog qhov pom tseeb, thiab nws muaj ntau yam kev siv hauv kev tsim khoom lag luam.

Txoj kev npaj

Muaj ntau txoj hauv kev rau kev npaj cov ferrous sulfate heptahydrate, thiab cov txheej txheem feem ntau yog raws li nram no:

1. Kev npaj cov sulfuric acid thiab ferrous hmoov.

2. Kev npaj cov tshuaj sulfuric acid thiab ferrous ingot.

3. Kev npaj ntawm sulfuric acid thiab ferrous ammonia.

Yuav tsum nco ntsoov tias cov xwm txheej ntawm cov tshuaj tiv thaiv yuav tsum tau tswj hwm nruj me ntsis thaum lub sijhawm npaj kom tsis txhob muaj cov pa phem thiab kev poob tsis tsim nyog.

Kev Ruaj Ntseg

Ferrous sulfate heptahydrate muaj qee qhov kev pheej hmoo, yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:

1. Ferrous sulfate heptahydrate yog ib qho tshuaj lom thiab yuav tsum tsis txhob kov ncaj qha. Yuav tsum tsis txhob ua pa, noj thiab kov daim tawv nqaij thiab qhov muag.

2. Thaum npaj thiab siv ferrous sulfate heptahydrate, yuav tsum tau ceev faj kom tiv thaiv cov pa phem thiab hluav taws thiab kev tawg.

3. Thaum lub sijhawm khaws cia thiab thauj mus los, yuav tsum tau ceev faj kom tsis txhob muaj kev sib cuag nrog cov tshuaj xws li oxidants, acids thiab alkalis kom tsis txhob muaj kev tsis haum thiab kev raug mob.

Kev Txheeb Xyuas

Hauv kev xaus lus, 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 them sai sai rau nws qhov kev pheej hmoo, thiab yuav tsum tau ua cov kev ntsuas tsim nyog rau kev khaws cia, kev thauj mus los thiab kev siv kom ntseeg tau tias muaj kev nyab xeeb ntawm tus kheej thiab kev tiv thaiv ib puag ncig.

Tib lub sijhawm, yuav tsum tau them sai sai rau kev txuag cov peev txheej hauv cov txheej txheem ntawm kev siv kom tsis txhob muaj pov tseg thiab ua qias tuaj.
