I-Magnesium sulfate heptahydrate, eyaziwa nangokuthi i-sulphobitter, usawoti obabayo, usawoti we-cathartic, usawoti we-Epsom, ifomula yamakhemikhali i-MgSO4·7H2O), imhlophe noma ayinambala amakristalu e-acicular noma a-oblique columnar, ayinaphunga, ipholile futhi iyababa kancane. Ngemva kokubola kokushisa, amanzi e-crystalline asuswa kancane kancane abe yi-magnesium sulfate engenamanzi. Isetshenziswa kakhulu ekwenziweni komanyolo, isikhumba, ukuphrinta nokudaya, i-catalyst, ukwenza iphepha, amapulasitiki, i-porcelain, imibala, umentshisi, izinto eziqhumayo nezinto ezingashi. Ingasetshenziswa ekunyatheliseni nasekudayeni indwangu encane kakotini kanye nesilika, njenge-ejenti yesisindo sikakotini kanye nokugcwalisa imikhiqizo ye-kapok, futhi isetshenziswe njengosawoti we-Epsom kwezokwelapha.
Izakhiwo zomzimba:
Ukubukeka kanye nezakhiwo: kungokwesistimu yekristalu ye-rhombic, yamakhona amane ikristalu ye-granular noma ye-rhombic, ayinambala, icacile, ihlanganiswe ukuze ikhanye ingilazi emhlophe, ephuzi noma eluhlaza. Isimo sayo sinama-fibrous, acicular, granular noma impuphu. Ayinaphunga, inambitheka ebabayo.
Ukuncibilika: Kuncibilika kalula emanzini, kuncibilika kancane ku-ethanol kanye ne-glycerol.
Izakhiwo zamakhemikhali:
Ukuzinza: Kuzinzile emoyeni omanzi ngaphansi kuka-48.1 ° C. Kulula ukukwamukela emoyeni ofudumele nowomile. Uma kuphakeme kuno-48.1 ° C, kulahlekelwa amanzi acwebezelayo bese kuba yi-sulfate yomlingo. Ngesikhathi esifanayo, i-magnesium sulfate iyakhukhuleka. Ku-70-80 ° C, kulahlekelwa amanzi acwebezelayo amane, kulahlekelwa amanzi acwebezelayo amahlanu ku-100 ° C, kanye namanzi acwebezelayo ayisithupha ku-150 ° C. Ku-200 ° C i-magnesium-like water sulfate, izinto eziphelelwe amanzi zifakwa emoyeni omanzi ukuze ziphinde zimunce amanzi. Esixazululweni esigcwele se-magnesium sulfate, i-crystalline ehlanganiswe ngamanzi enamanzi angu-1, 2, 3, 4, 5, 6, kanye nangu-12 ingaba yi-crystal. Ku--1.8 ~ 48.18 ° C isixazululo samanzi esigcwele, i-magnesium sulfate iyakhukhuleka, kanti esixazululweni samanzi esigcwele esingu-48.1 kuya ku-67.5 ° C, i-magnesium sulfate iyakhukhuleka. Uma kuphakeme kuno-67.5 ° C, i-magnesium sulfate iyakhukhuleka. Kwakhiqizwa ukuncibilika kwe-alien phakathi kuka-° C ne-magnesium sulfate ye-sulfate yamanzi emihlanu noma emine. I-magnesium sulfate yaguqulwa yaba i-magnesium sulfate ku-106 ° C. I-magnesium sulfate yaguqulwa yaba i-magnesium sulfate ku-122-124 ° C. I-magnesium sulfate iguqulwa ibe yi-magnesium sulfate eqinile ku-161 ～ 169 ℃.

Inani le-PH: 7, Okungathathi hlangothi
Isicelo Esiyinhloko:
1) Insimu yokudla
Njenge-ejenti yokuqinisa ukudla. Imithetho yezwe lami ingasetshenziswa emikhiqizweni yobisi, enenani eliphakathi kuka-3 kuya ku-7g/kg; inani lokusetshenziswa koketshezi lokuphuza kanye neziphuzo zobisi lingu-1.4 ～ 2.8g/kg; ukusetshenziswa okuphezulu kotshwala obunamaminerali kungu-0.05g/kg.
2) Insimu Yezimboni
Isetshenziswa kakhulu nosawoti we-calcium emanzini ewayini. Ukwengeza emanzini angu-4.4g/100L kungandisa ubulukhuni nge-degree eli-1. Uma isetshenziswa, ingadala ukubaba futhi ikhiphe iphunga le-hydrogen sulfide.
Kusetshenziswa njenge-tone, iziqhumane, ukwenza amaphepha, i-porcelain, umanyolo, kanye ne-laxes yomlomo yezokwelapha, njll., izithasiselo zamanzi amaminerali.
3) Insimu yezolimo
I-Magnesium sulfate isetshenziswa kumanyolo kwezolimo ngoba i-magnesium ingenye yezingxenye eziyinhloko ze-chlorophyll. Izitshalo zezitshalo ezifakwe emabhodweni noma i-magnesium zivame ukusetshenziswa, njengotamatisi, amazambane, ama-rose, njll. I-Magnesium sulfate inezinga eliphezulu lokuncibilika uma kuqhathaniswa neminye imanyolo. I-Magnesium sulfate nayo isetshenziswa njengosawoti wokugeza.
Indlela yokulungiselela:
1) Indlela 1:
I-asidi ye-sulfuric ifakwa ku-magnesium carbonate yemvelo (i-magnetite), i-carbon dioxide iyasuswa, iphinde isetshenziswe, i-Kieserite (MgSO4·H2O) iyancibilikiswa emanzini ashisayo bese isetshenziswa kabusha, yenziwe ngamanzi olwandle.
2) Indlela 2 (Indlela yokukhipha amanzi olwandle)
Ngemva kokuba i-brine iphele ngendlela ye-brine, kukhiqizwa usawoti oshisayo kakhulu, futhi ukwakheka kwawo kuyi-MgSO4>. 30%, i-MgCl2 cishe i-7%, i-KCl cishe i-0.5%. I-bittern ingasuswa ngesisombululo se-MgCl2 esingu-200g/L ku-48℃, ngesisombululo se-NaCl esincane kanye nesisombululo se-MgSO4 esiningi. Ngemva kokuhlukaniswa, i-MgSO4·7H2O eluhlaza yancishiswa ngokupholisa ku-10℃, futhi umkhiqizo oqediwe watholakala ngokuphinda kusetshenziswe i-crystallization yesibili.
3) Indlela 3 (Indlela ye-Sulfuric acid)
Ethangini lokungahlanganisi, i-rhombotrite yafakwa kancane kancane emanzini kanye notshwala obungumama, yabe isisuswa nge-sulfuric acid. Umbala washintsha kusuka kumbala womhlaba waba obomvu. I-pH yalawulwa yaba yi-Be 5, kanti ubuningi obuhlobene babuyi-1.37 ~ 1.38(39 ~ 40° Be). Isixazululo sokungahlanganisi sahlungwa ku-80℃, kwabe sekulungiswa i-pH yaba yi-4 nge-sulfuric acid, kwanezelwa amakristalu embewu afanele, futhi apholiswa ku-30℃ ukuze kufakwe ikristalu. Ngemva kokuhlukaniswa, umkhiqizo oqediwe womiswa ku-50~55℃, bese utshwala obungumama bubuyiselwa ethangini lokungahlanganisi. I-Magnesium sulfate heptahydrate ingalungiswa nangokususa ukusabela kwe-sulfuric acid ephansi ene-65% magnesia ku-momorrhea ngokuhlunga, ukuchelela, ukuhluzwa, ukuhlukaniswa kwe-centrifugal kanye nokomisa, yenziwe nge-magnesium sulfate.
Isilinganiso samakhemikhali okusabela: MgO+H2SO4+6H2O→MgSO4·7H2O.
Izinyathelo zokuqapha zokuhamba:Ukupakishwa kufanele kuphelele lapho kuthuthwa, futhi umthwalo kufanele uphephe. Ngesikhathi sokuthuthwa, qiniseka ukuthi isitsha akufanele sivuze, sibhidlike, siwe, noma sonakale. Akuvunyelwe ngokuphelele ukuxuba nama-asidi namakhemikhali adliwayo. Ngesikhathi sokuthuthwa, kufanele sivikelwe elangeni, emvuleni kanye nasekushiseni okuphezulu. Imoto kufanele ihlanzwe kahle ngemva kokuthuthwa.
Izinyathelo zokuphepha zokusebenza:Ukusebenza okuvaliwe nokuqinisa umoya. Umqhubi kumele alandele ngokuqinile izinqubo zokusebenza ngemuva kokuqeqeshwa okukhethekile. Kunconywa ukuthi abaqhubi bagqoke izifihla-buso zothuli lwezihlungi zokuzimunca, izibuko zokuvikela zokuphepha zamakhemikhali, bagqoke izingubo zokusebenza zokungena ezilwa nobuthi, kanye namagilavu erabha. Gwema uthuli. Gwema ukuthintana nama-asidi. Khanyisa bese ususa kancane iphakheji ukuze uvimbele ukuthi iphakheji ingonakali. Ifakwe imishini yokwelapha ephuthumayo evuzayo. Izitsha ezingenalutho zingaba yizinsalela eziyingozi. Lapho ukugcwala kothuli emoyeni kudlula izinga, kumele sigqoke imaski yothuli lwezihlungi zokuzimunca. Lapho ukuhlenga noma ukuphuma endaweni ephuthumayo, kufanele kugqokwe izifihla-buso zokulwa namagciwane.
Izinyathelo zokuphepha zokugcina:Igcinwe endaweni yokugcina izinto epholile, enomoya. Hlala kude nomlilo nokushisa. Gcina ngokwehlukana ne-asidi futhi ugweme ukugcina izinto ezixubile. Indawo yokugcina izinto kufanele ifakwe izinto ezifanele ukuvimba ukuvuza.
