Magnesium sulfate heptahydrate, eyaziwa ngokuba yi-sulphobitter, ityuwa ekrakra, ityuwa ye-cathartic, ityuwa ye-Epsom, i-chemical formula MgSO4 · 7H2O), i-white or colorless acicular or oblique columnar crystals, i-odorless, ipholile kwaye ibuhlungu kancinci.Emva kokubola kobushushu, amanzi ekristale asuswa ngokuthe ngcembe kwi-anhydrous magnesium sulfate.Isetyenziswa ikakhulu ekwenzeni isichumiso, ngethwathwa, ukuprinta kunye nokudaya, catalyst, papermaking, iiplastiki, porcelain, pigments, imatshisi, iziqhushumbisi kunye nezinto ezingatshiyo.Ingasetyenziselwa ukuprinta kunye nokudaya ilaphu elicekethekileyo lomqhaphu kunye nesilika, njenge-arhente yobunzima bomqhaphu wesilika kunye nokuzaliswa kweemveliso ze-kapok, kwaye isetyenziswe njengetyuwa ye-Epsom kumayeza.
Iimpawu ezibonakalayo:
Imbonakalo kunye neempawu: yeyenkqubo ye-crystal ye-rhombic, kwiikona ezine ze-granular okanye i-rhombic crystal, i-colorless, i-transparent, i-aggregate ye-white, i-rose okanye i-glass luster eluhlaza.Imilo i-fibrous, i-acicular, i-granular okanye i-powder.Ivumba elibi, incasa ekrakra.
Ukunyibilika: Inyibilika ngokulula emanzini, inyibilika kancinane kwi-ethanol kunye ne-glycerol.
Iimpawu zemichiza:
Ukuzinza: Ukuzinza emoyeni omanzi ngaphantsi kwe-48.1 ° C. Kulula ukuhlala emoyeni ofudumeleyo kunye nowomileyo.Xa ingaphezulu kwe-48.1 ° C, ilahlekelwa ngamanzi ayikristale kwaye ibe yisulfate yomlingo.Ngexesha elifanayo, i-magnesium sulfate iyancipha.Kwi-70-80 ° C, ilahlekelwa yi-4 crystal yamanzi, ilahlekelwa yi-5 crystal yamanzi kwi-100 ° C, kwaye ilahlekelwe ngamanzi angama-crystal angama-6 kwi-150 ° C. Kwi-200 ° C i-Magnesium -njengamanzi sulfate, izinto ezichithwayo zifakwe emoyeni omanzi. ukufunxa kwakhona amanzi.Kwisisombululo esigcweleyo se-magnesium sulfate, i-crystalline edibeneyo yamanzi kunye ne-1, 2, 3, 4, 5, 6, kunye ne-12 yamanzi ingaba yikristale.Kwi--1.8 ~ 48.18 ° C i-saturated aqueous solution, i-magnesium sulfate iyancipha, kwaye kwisisombululo samanzi esigcweleyo se-48.1 ukuya kwi-67.5 ° C, i-magnesium sulfate iyancipha.Xa iphezulu kune-67.5 ° C, i-magnesium sulfate iyancipha.Ukunyibilika okungaqhelekanga phakathi kwe° C kunye ne-magnesium sulfate ye-sulfate yamanzi emihlanu okanye emine iye yenziwa.I-Magnesium sulfate yaguqulwa yaba yi-magnesium sulfate kwi-106 ° C. I-Magnesium sulfate yaguqulwa yaba yi-magnesium sulfate kwi-122-124 ° C. I-Magnesium sulfate iguqulela kwi-stable magnesium sulfate kwi-161 · 169 ℃.
Ubutyhefu: Ityhefu
PH ixabiso: 7, Phakathi
Usetyenziso Olungundoqo:
1) Intsimi yokutya
Njenge-arhente yokomeleza ukutya.imimiselo yelizwe lam ingasetyenziselwa iimveliso zobisi, kunye nenani le-3 ukuya kwi-7g / kg;ubungakanani bokusetyenziswa ekuseleni nakwiziselo zobisi yi-1.4 ～ 2.8g/kg;olona setyenziso luphezulu kwiziselo zeminerali yi-0.05g/kg.
2) Indawo yoshishino
Isetyenziswa kakhulu kunye netyuwa ye-calcium kumanzi oomama wewayini.Ukongeza kwi-4.4g / 100L amanzi kunokunyusa ubunzima nge-1 degree.Xa isetyenziswa, inokuvelisa ubukrakra kwaye ivelise ivumba lehydrogen sulfide.
Isetyenziswe njengethoni, iziqhushumbisi, i-papermaking, i-porcelain, isichumisi, kunye ne-laxes yomlomo yonyango, njl., izongezo zamanzi amaminerali.
3) Intsimi yezolimo
I-Magnesium sulfate isetyenziswa kwisichumiso kwezolimo kuba i-magnesium yenye yezona zinto ziphambili kwi-chlorophyll.Izityalo zezityalo ze-potted okanye i-magnesium zidla ngokusetyenziswa, ezifana netamatato, iitapile, i-roses, njl njl. I-Magnesium sulfate inezinga eliphezulu lokunyibilika xa kuthelekiswa nezinye izichumisi.IMagnesium sulfate ikwasetyenziswa njengetyuwa yokuhlamba.
Indlela yokulungiselela:
1) Indlela yoku-1:
I-asidi ye-sulfuric yongezwa kwi-magnesium carbonate yendalo (i-magnesite), i-carbon dioxide iyasuswa, iphinde ihlaziywe, i-Kieserite (MgSO4 · H2O) ichithwa emanzini ashushu kwaye iphinda ihlaziywe, yenziwe ngamanzi olwandle.
2) Indlela yesi-2 (indlela yokuphuma kwamanzi olwandle)
Emva kokuba i-brine ikhutshwe ngumphunga ngendlela ye-brine, ubushushu obuphezulu betyuwa buveliswa, kwaye ukubunjwa kwayo nguMgSO4>.30 ekhulwini.35%, MgCl2 malunga 7%, KCl malunga 0.5%.I-bittern inokutsalwa ngesisombululo se-MgCl2 se-200g / L kwi-48 ℃, kunye nesisombululo esincinci se-NaCl kunye nesisombululo se-MgSO4.Emva kokwahlula, i-MgSO4 · 7H2O ekrwada yancitshiswa ngokupholisa kwi-10 ℃, kwaye imveliso egqityiweyo yafunyanwa nge-recrystallization yesibini.
3) Indlela ye-3 (indlela ye-Sulfuric acid)
Kwitanki ye-neutralization, i-rhombotrite yongezwa ngokukhawuleza emanzini kunye notywala komama, kwaye emva koko ingathathi hlangothi nge-asidi ye-sulfuric.Umbala watshintsha ukusuka kumbala womhlaba ukuya kubomvu.I-pH yayilawulwa ukuba ibe yi-5, kwaye ubuninzi bobuninzi be-1.37 ~ 1.38 (39 ~ 40 ° Be).Isisombululo se-neutralization sahluzwa kwi-80 ℃, emva koko i-pH yahlengahlengiswa kwi-4 nge-asidi ye-sulfuric, i-crystals yembewu efanelekileyo yongezwa, kwaye ipholile kwi-30 ℃ ye-crystallization.Emva kokuhlukana, imveliso egqityiweyo yomiswa kwi-50 ~ 55 ℃, kwaye utywala omama bubuyiselwa kwi-tank neutralization.I-Magnesium sulfate heptahydrate inokulungiswa ngokuphendula ngokungathathi hlangothi koxinzelelo oluphantsi lwesulfuric acid kunye ne-65% ye-magnesia kwi-momorrhea ngokucoca, imvula, ukugxila, icrystallization, ukwahlukana kwe-centrifugal kunye nokoma, yenziwe nge-magnesium sulfate.
I-reaction chemical equation: MgO+H2SO4+6H2O→MgSO4·7H2O.
