I-Magnesium Sulphate Heptahydrate

I-Magnesium sulfate heptahydrate, ekwaziwa ngokuba yi-sulphobitter, ityuwa ekrakra, ityuwa ethambileyo, ityuwa ye-Epsom, ifomula yekhemikhali i-MgSO4·7H2O), yikristale emhlophe okanye engenambala ye-acicular okanye ye-oblique columnar, ayinavumba, ipholile kwaye ikrakra kancinci. Emva kokubola kobushushu, amanzi ekristale asuswa kancinci kancinci abe yi-magnesium sulfate engenamanzi. Isetyenziswa kakhulu ekwenzeni isichumiso, isikhumba, ukuprinta kunye nokudaya, i-catalyst, ukwenza iphepha, iiplastiki, i-porcelain, imibala, imatshisi, izinto eziqhumayo kunye nezinto ezingatshiyo. Ingasetyenziselwa ukuprinta kunye nokudaya ilaphu lekotoni elincinci kunye nesilika, njengesixhobo sobunzima kwisilika yekotoni kunye nokuzalisa iimveliso ze-kapok, kwaye isetyenziswe njengetyuwa ye-Epsom kunyango.

Iimpawu ezibonakalayo:

Inkangeleko kunye neempawu: zezenkqubo yekristale ye-rhombic, kwiikona ezine zekristale ye-granular okanye ye-rhombic, ayinambala, icacile, ihlanganiswe ukuze ikhanyise iglasi emhlophe, i-rose okanye eluhlaza. Imilo yayo ine-fibrous, i-acicular, i-granular okanye i-powder. Ayinavumba, incasa ekrakra.

Ukunyibilika: Inyibilika lula emanzini, inyibilika kancinci kwi-ethanol kunye ne-glycerol.

Iimpawu zekhemikhali:

Uzinzo: Izinzile emoyeni ofumileyo ongaphantsi kwama-48.1 ° C. Kulula ukuyigcina emoyeni ofudumeleyo nowomileyo. Xa iphezulu kune-48.1 ° C, ilahlekelwa ngamanzi acwebezelayo ize ibe yi-sulfate yomlingo. Kwangaxeshanye, i-magnesium sulfate iyatshiseka. Kwi-70-80 ° C, ilahlekelwa ngamanzi acwebezelayo amane, ilahlekelwe ngamanzi acwebezelayo amahlanu kwi-100 ° C, kwaye ilahlekelwe ngamanzi acwebezelayo amathandathu kwi-150 ° C. Kwi-200 ° C i-magnesium-like water sulfate, izinto ezicociweyo zifakwa emoyeni ofumileyo ukuze ziphinde zifunxe amanzi. Kwisisombululo esifumileyo se-magnesium sulfate, i-crystalline edityaniswe ngamanzi enamanzi ayi-1, 2, 3, 4, 5, 6, kunye ne-12 ingaba yi-crystal. Kwisisombululo samanzi esifumileyo esingu--1.8 ~ 48.18 ° C, i-magnesium sulfate iyatshiseka, kwaye kwisisombululo samanzi esifumileyo esingu-48.1 ukuya kwi-67.5 ° C, i-magnesium sulfate iyatshiseka. Xa iphezulu kune-67.5 ° C, i-magnesium sulfate iyatsha. Ukunyibilika kwe-alien phakathi kwe-° C kunye ne-magnesium sulfate ye-sulfate yamanzi emihlanu okanye emine kwenziwa. 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 iguqulwa ibe yi-magnesium sulfate ezinzileyo kwi-161 ～ 169 ℃.

Ubuthi: Ityhefu

Ixabiso le-PH: 7, elingathathi cala

Isicelo Esiphambili:

1) Intsimi yokutya

Njengearhente yokuqinisa ukutya. Imithetho yelizwe lam ingasetyenziselwa iimveliso zobisi, enomlinganiselo we-3 ukuya kwi-7g/kg; ubungakanani bokusetyenziswa kwiziselo zokusela kunye neziselo zobisi yi-1.4 ～ 2.8g/kg; ukusetyenziswa okuphezulu kwiziselo zeminerali yi-0.05g/kg.

2) Intsimi yemizi-mveliso

Isetyenziswa kakhulu kunye netyuwa yecalcium emanzini ewayini. Ukongeza kwi-4.4g/100L yamanzi kunokunyusa ubunzima nge-1 degree. Xa isetyenziswa, inokuvelisa ubukrakra kwaye ivelise ivumba le-hydrogen sulfide.

Isetyenziswa njengethoni, izinto eziqhumayo, ukwenza iphepha, i-porcelain, isichumisi, kunye ne-oral laxes zonyango, njl.njl., izongezo zamanzi amaminerali.

3) Intsimi yezolimo

I-Magnesium sulfate isetyenziswa kwisichumisi kwezolimo kuba i-magnesium yenye yezona zinto ziphambili ze-chlorophyll. Izityalo zezityalo ezifakwe kwiimbiza okanye i-magnesium zihlala zisetyenziswa, ezifana neetumato, iitapile, iirozi, njl. I-Magnesium sulfate inomlinganiselo ophezulu wokunyibilika xa ithelekiswa nezinye izichumisi. I-Magnesium sulfate ikwasetyenziswa njengetyuwa yokuhlamba.

Indlela yokulungiselela:

1) Indlela 1:

I-asidi ye-sulfuric yongezwa kwi-magnesium carbonate yendalo (i-magnetite), i-carbon dioxide iyasuswa, iphinde i-crystallized, i-Kieserite (MgSO4·H2O) iyanyibilika emanzini ashushu ize iphinde i-crystallized, yenziwe ngamanzi olwandle.

2) Indlela yesi-2 (Indlela yokukhuhla amanzi olwandle)

Emva kokuba ityuwa inyibilikisiwe ngendlela yetyuwa, ityuwa eshushu kakhulu iyaveliswa, kwaye ukwakheka kwayo yiMgSO4>. 30 ekhulwini. 35%, iMgCl2 malunga ne-7%, iKCl malunga ne-0.5%. I-bittern ingatsalwa ngesisombululo seMgCl2 se-200g/L kwi-48℃, ngesisombululo seNaCl esincinci kunye nesisombululo seMgSO4 esingaphezulu. Emva kokuhlukana, iMgSO4·7H2O eluhlaza yatsalwa ngokuphola kwi-10℃, kwaye imveliso egqityiweyo yafunyanwa ngokuphinda i-crystallization yesibini.

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

Kwitanki yokungaxubeki, i-rhombotrite yongezwa kancinci emanzini nakwi-mother liquor, yaze yaxubekishwa nge-sulfuric acid. Umbala watshintsha ukusuka kumbala womhlaba ukuya kubomvu. I-pH yalawulwa yaba yi-Be 5, kwaye ubuninzi be-relative yayiyi-1.37 ~ 1.38(39 ~ 40° Be). Isisombululo sokungaxubeki sahluzwa kwi-80℃, emva koko i-pH yalungiswa yaba yi-4 nge-sulfuric acid, kongezwa iikristale zembewu ezifanelekileyo, zaza zapholiswa zaya kwi-30℃ ukuze zinyibilike. Emva kokuhlukana, imveliso egqityiweyo yomiswa kwi-50~55℃, kwaye utywala be-mother bubuyiselwa kwi-momorrhea. I-Magnesium sulfate heptahydrate ingalungiswa ngokungaxubeki kwe-low concentration sulfuric acid kunye ne-65% magnesia kwi-momorrhea ngokuhluza, ukuhlanjwa, ukuxinana, ukunyibilika, ukuhlukaniswa kwe-centrifugal kunye nokoma, yenziwe nge-magnesium sulfate.

I-equation yekhemikhali ye-reaction: MgO+H2SO4+6H2O→MgSO4·7H2O.

Amanyathelo okhuseleko okuthutha:Ukupakisha kufuneka kugqitywe xa kuthuthwa, kwaye umthwalo kufuneka ukhuseleke. Ngexesha lokuthuthwa, qiniseka ukuba isikhongozeli asifanele sivuze, sidilike, siwe, okanye sonakale. Akuvumelekanga ngokupheleleyo ukuxuba nee-asidi kunye neekhemikhali ezityiwayo. Ngexesha lokuthuthwa, kufuneka sikhuselwe elangeni, emvuleni nasebushushwini obuphezulu. Isithuthi kufuneka sicocwe kakuhle emva kokuthuthwa.

Amanyathelo okhuseleko okusebenza:Ukusebenza okuvaliweyo kunye nokuqinisa umoya. Umqhubi kufuneka alandele ngokungqongqo iinkqubo zokusebenza emva koqeqesho olukhethekileyo. Kucetyiswa ukuba abaqhubi banxibe iimaski zothuli zokuzihluza, iiglasi zokhuseleko lweekhemikhali, banxibe iimpahla zokusebenza ezithintela ityhefu, kunye neeglavu zerabha. Kuphephe uthuli. Kuphephe ukudibana nee-asidi. Khanyisa kwaye ususe kancinci iphakheji ukuze uthintele ukuba iphakheji ingonakali. Ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo. Izikhongozeli ezingenanto zinokuba ziintsalela eziyingozi. Xa uxinano lothuli emoyeni ludlula umgangatho, kufuneka sinxibe imaski yothuli yokuzihluza. Xa kuhlangulwa okanye kuphuma abantu ngexesha likaxakeka, kufuneka kunxitywe iimaski zokulwa neentsholongwane.

Amanyathelo okukhusela ukugcina:Gcina kwindawo yokugcina izinto epholileyo nengenamoya. Hlala kude nomlilo nobushushu. Gcina ngokwahlukileyo kwi-asidi kwaye uphephe ukugcina izinto ezixutyiweyo. Indawo yokugcina izinto kufuneka ixhotyiswe ngezinto ezifanelekileyo zokuthintela ukuvuza.
