I-Magnesium sulphate Heptahydrate

I-Magnesium sulfate heptahydrate, eyaziwa nangokuthi i-sulphobitter, usawoti obabayo, usawoti we-cathartic, usawoti we-Epsom, ifomula yamakhemikhali i-MgSO4 · 7H2O), i-acicular acicular noma i-oblique columnar crystals emhlophe noma engenambala, ayinaphunga, ipholile futhi inomunyu kancane.Ngemva kokubola kokushisa, amanzi ayikristalu kancane kancane asuswa ku-anhydrous magnesium sulfate.Isetshenziswa kakhulu ekwenzeni umanyolo, isikhumba, ukuphrinta nokudaya, i-catalyst, ukwenza amaphepha, amapulasitiki, i-porcelain, i-pigments, umentshisi, iziqhumane nezinto ezingashi.Ingasetshenziselwa ukuphrinta nokudaya indwangu kakotini encane kanye nosilika, njenge-ejenti yesisindo sikasilika kakotini kanye nokugcwalisa imikhiqizo ye-kapok, futhi isetshenziswe njengosawoti we-Epsom kwezokwelapha.

Izinto ezibonakalayo:

Ukubukeka kanye nezakhiwo: kungowe-rhombic crystal system, emakhoneni amane i-granular noma i-rhombic crystal, engenambala, esobala, inhlanganisela yokucwebezela kwengilazi emhlophe, e-rose noma eluhlaza.Umumo une-fibrous, i-acicular, i-granular noma impushana.Ukunambitheka okubabayo nokungenaphunga.

Ukunyibilika: Incibilika kalula emanzini, inyibilika kancane ku-ethanol ne-glycerol.

Izakhiwo zamakhemikhali:

Ukuzinza: Izinzile emoyeni oswakeme ngaphansi kuka-48.1 ° C. Kulula ukuhlala emoyeni ofudumele nowomile.Uma ingaphezu kuka-48.1 ° C, ilahlekelwa amanzi ayikristalu bese iba yi-magic sulfate.Ngesikhathi esifanayo, i-magnesium sulfate iyancipha.Ku-70-80 ° C, ilahlekelwa amanzi angama-crystal angu-4, ilahlekelwa amanzi angama-crystal angu-5 ku-100 ° C, futhi ilahlekelwe amanzi angama-crystal angu-6 ngo-150 ° C. Ku-200 ° C I-Magnesium -njengamanzi sulfate, izinto eziphelelwe amanzi zifakwa emoyeni onomswakama. ukumunca kabusha amanzi.Kusixazululo esigcwele se-magnesium sulfate, ikristalu ehlanganiswe namanzi enamanzi angu-1, 2, 3, 4, 5, 6, kanye nayi-12 ingaba yikristalu.Ku--1.8 ~ 48.18 ° C isixazululo samanzi esigcwele, i-magnesium sulfate iyancishiswa, futhi kusisombululo samanzi esigcwele esingu-48.1 kuya ku-67.5 ° C, i-magnesium sulfate iyancipha.Lapho ingaphezulu kuka-67.5 ° C, i-magnesium sulfate iyancipha.Ukuncibilika kwe-alien phakathi kuka-° C kanye ne-magnesium sulfate ye-sulfate yamanzi emihlanu noma emine kwakhiqizwa.I-Magnesium sulfate yaguqulwa yaba yi-magnesium sulfate ku-106 ° C. I-Magnesium sulfate yaguqulwa yaba yi-magnesium sulfate ku-122-124 ° C. I-Magnesium sulfate iguqulela ku-magnesium sulfate ezinzile ku-161 ~ 169 ℃.

Ubuthi: Bunobuthi

PH inani: 7, Maphakathi nendawo

Isicelo Esiyinhloko:

1) Inkambu yokudla

Njenge-ejenti yokuqinisa ukudla.imithetho yezwe lami ingasetshenziswa emikhiqizweni yobisi, enenani elingu-3 kuya ku-7g/kg;inani elisetshenziswa ekuphuzeni uketshezi kanye neziphuzo zobisi ngu-1.4 ~ 2.8g/kg;ukusetshenziswa okuphezulu eziphuzweni zamaminerali ngu-0.05g/kg.

2) Inkambu yezimboni

Isetshenziswa kakhulu nosawoti we-calcium emanzini omama wewayini.Ukwengeza ku-4.4g/100L amanzi kungakhuphula ubulukhuni ngedigri engu-1.Uma isetshenziswa, ingaveza ukubaba futhi ikhiqize iphunga le-hydrogen sulfide.

Isetshenziswa njengethoni, iziqhumane, ukwenza iphepha, i-porcelain, umanyolo, kanye nokulahlwa komlomo wezokwelapha, njll., izithasiselo zamanzi amaminerali.

3) Insimu yezolimo

I-Magnesium sulfate isetshenziswa kumanyolo kwezolimo ngoba i-magnesium ingenye yezingxenye eziyinhloko ze-chlorophyll.Izitshalo zezitshalo ze-potted noma i-magnesium zivame ukusetshenziswa, njengotamatisi, amazambane, ama-roses, njll. I-Magnesium sulfate inezinga eliphezulu lokuncibilika uma kuqhathaniswa namanye ama-fertilizer.I-Magnesium sulfate nayo isetshenziswa njengosawoti wokugeza.

Indlela yokulungiselela:

1) Indlela 1:

I-Sulfuric acid yengezwe ku-magnesium carbonate yemvelo (i-magnesite), i-carbon dioxide isusiwe, i-recrystallized, i-Kieserite (MgSO4 · H2O) ichithwa emanzini ashisayo futhi iphinde ifakwe emanzini olwandle.

2) Indlela yesi-2 (Indlela yokugeleza kwamanzi olwandle)

Ngemva kokuba i-brine ihwamuke ngendlela ye-brine, izinga lokushisa eliphakeme likasawoti liyakhiqizwa, futhi ukwakheka kwalo nguMgSO4>.Amaphesenti angama-30.35%, MgCl2 mayelana 7%, KCl mayelana 0.5%.I-Bittern ingacwiliswa ngesixazululo se-MgCl2 esingu-200g/L ku-48℃, ngesisombululo se-NaCl esincane kanye nesixazululo se-MgSO4 esengeziwe.Ngemva kokuhlukana, i-MgSO4 · 7H2O engahluziwe yancipha ngokupholisa ngo-10℃, futhi umkhiqizo oqediwe watholwa ngokuphinda kwenziwe kabusha.

3) Indlela yesi-3 (indlela ye-Sulfuric acid)

Ethangini le-neutralization, i-rhombotrite yengezwa kancane kancane emanzini notshwala kamama, bese ihlanganiswa ne-sulfuric acid.Umbala washintsha kusukela kumbala womhlaba waba bomvu.I-pH yayilawulwa ukuze ibe ngu-5, futhi ukuminyana okuhlobene kwaba ngu-1.37 ~ 1.38(39 ~ 40° Be).Isixazululo se-neutralization sahlungwa ku-80 ℃, kwase kuthi i-pH yalungiswa yaba ngu-4 nge-sulfuric acid, amakristalu embewu afanelekile afakwa, futhi apholiswa ku-30 ​​℃ ukuze kukhanye.Ngemuva kokuhlukaniswa, umkhiqizo oqediwe uyomiswa ku-50 ~ 55 ℃, futhi utshwala bomama bubuyiselwa ethangini lokungathathi hlangothi.I-Magnesium sulfate heptahydrate ingabuye ilungiswe ngokushintsha ukusabela kwe-low concentration sulfuric acid ne-65% magnesia ku-momorrhea ngokusebenzisa ukuhlunga, imvula, ukugxila, i-crystallization, ukuhlukaniswa kwe-centrifugal nokoma, yenziwe nge-magnesium sulfate.

Izibalo zamakhemikhali ezisabelayo: MgO+H2SO4+6H2O→MgSO4·7H2O.
