Magnesium Sulphate Heptahydrate

Magnesium sulfate heptahydrate, inozivikanwawo se sulphobitter, munyu unovava, munyu we cathartic, munyu we Epsom, makemikari fomura MgSO4·7H2O), ine makristaro machena kana asina ruvara acicular kana oblique columnar, haina hwema, inotonhorera uye inovava zvishoma. Mushure mekuora kwekupisa, mvura ye crystalline inobviswa zvishoma nezvishoma kuita anhydrous magnesium sulfate. Inonyanya kushandiswa mukugadzira fetereza, dehwe, kudhinda nekudhaya, catalyst, kugadzira mapepa, mapurasitiki, porcelain, pigments, machisi, zvinoputika nezvinhu zvisingatsvi. Inogona kushandiswa kudhinda nekudhaya jira rekotoni rakatetepa nesirika, sechinhu chinorema chekotoni sirika uye chinozadza zvigadzirwa zve kapok, uye inoshandiswa semunyu we Epsom mukurapa.

Zvimiro zvemuviri:

Chitarisiko uye hunhu: ndeye rhombic crystal system, yemakona mana granular kana rhombic crystal, isina ruvara, yakajeka, yakasanganiswa yegirazi jena, rose kana girini. Chimiro chayo chine fibrous, acicular, granular kana upfu. Hainhuhwi, inovava.

Kunyungudika: Inonyungudika nyore mumvura, inonyungudika zvishoma mu ethanol ne glycerol.

Hunhu hwemakemikari:

Kugadzikana: Kugadzikana mumhepo ine hunyoro pasi pe48.1 ° C. Zviri nyore kugara mumhepo inodziya uye yakaoma. Kana yakakwira kupfuura 48.1 ° C, inorasikirwa nemvura yekristaro uye inova magic sulfate. Panguva imwe chete, magnesium sulfate inonaya. Pa70-80 ° C, inorasikirwa nemvura yekristaro ina, inorasikirwa nemvura yekristaro 5 pa100 ° C, uye inorasikirwa nemvura yekristaro 6 pa150 ° C. Pa200 ° C Magnesium-like water sulfate, zvinhu zvakaora mvura zvinoiswa mumhepo ine hunyoro kuti zvinyure mvura zvakare. Mumvura ine magnesium sulfate yakasviba, crystalline yakasanganiswa nemvura ine 1, 2, 3, 4, 5, 6, uye 12 mvura inogona kuva crystal. Mu -1.8 ~ 48.18 ° C saturated aqueous solution, magnesium sulfate inonaya, uye mumvura ine 48.1 kusvika 67.5 ° C, magnesium sulfate inonaya. Kana tembiricha yakakwira kupfuura 67.5°C, magnesium sulfate inodonha. Kunyunguduka kwemvura pakati pe°C nemagnesium sulfate yemvura 5 kana ina kwakagadzirwa. Magnesium sulfate yakachinjwa kuita magnesium sulfate pa106°C. Magnesium sulfate yakachinjwa kuita magnesium sulfate pa122-124°C. Magnesium sulfate inoshanduka kuita magnesium sulfate yakagadzikana pa161 ～ 169°C.

Huturu: Hune Chepfu

PH kukosha: 7, Kwakarerekera

Kushanda Kukuru:

1) Munda wezvekudya

Semushonga wekusimbisa chikafu, mitemo yenyika yangu inogona kushandiswa kune zvigadzirwa zvemukaka, nehuwandu hwe3 kusvika ku7g/kg; huwandu hwekushandiswa muzvinwiwa zvekunwa uye zvinwiwa zvemukaka i1.4 ～ 2.8g/kg; kushandiswa kwakanyanya muzvinwiwa zvine mineral i0.05g/kg.

2) Munda wemaindasitiri

Inonyanya kushandiswa nemunyu wecalcium mumvura yewaini. Kuwedzera ku4.4g/100L yemvura kunogona kuwedzera kuomarara kwayo nedhigirii rimwe chete. Kana ikashandiswa, inogona kuvava uye kunhuhwirira kwehydrogen sulfide.

Zvinoshandiswa semushonga wekuwedzera mvura ine zvicherwa, zvinoputika, kugadzira mapepa, porcelain, fetereza, uye mishonga yekurapa, nezvimwewo.

3) Munda wekurima

Magnesium sulfate inoshandiswa mufetereza mukurima nekuti magnesium chimwe chezvinhu zvikuru zvinoumba chlorophyll. Zvirimwa zvezvirimwa zviri muhari kana magnesium zvinowanzo shandiswa, zvakaita sematomatisi, mbatatisi, maruva, nezvimwewo. Magnesium sulfate ine mwero wepamusoro wekunyungudika kana tichienzanisa nedzimwe fetereza. Magnesium sulfate inoshandiswawo semunyu wekugezesa.

Nzira yekugadzirira:

1) Nzira 1:

Sulfuric acid inowedzerwa kune natural magnesium carbonate (magnetite), carbon dioxide inobviswa, inodzokororwa, Kieserite (MgSO4·H2O) inonyungudutswa mumvura inopisa uye inodzokororwa, yakagadzirwa nemvura yegungwa.

2) Nzira 2 (Nzira yekubuditsa mvura yegungwa)

Mushure mekunge mvura yapwanyika nekushandisa brine, munyu unobuda pakupisa kwakanyanya, uye musanganiswa wayo iMgSO4>. 30 muzana. 35%, MgCl2 inenge 7%, KCl inenge 0.5%. Munyu unogona kunyungudutswa neMgCl2 solution ye200g/L pa48℃, neNaCl solution shoma uye MgSO4 solution yakawanda. Mushure mekupatsanurwa, MgSO4·7H2O isina kucheneswa yakanyungudutswa nekutonhodza pa10℃, uye chigadzirwa chakapedzwa chakawanikwa nekudzokororazve kwechipiri.

3) Nzira 3 (Nzira yeSulfuric acid)

Mutangi rekusabvisa tsvina, rhombotrite yakazowedzerwa zvishoma nezvishoma mumvura nedoro remumvura, yozobviswa nesulfuric acid. Ruvara rwakachinja kubva paruvara rwevhu kuenda kutsvuku. pH yakadzorwa kuita Be 5, uye huwandu hwehuwandu hwaive 1.37 ~ 1.38(39 ~ 40° Be). Mhinduro yekusabvisa tsvina yakaseferwa pa80℃, pH yakabva yagadziriswa kuita 4 nesulfuric acid, makristaro embeu akakodzera akawedzerwa, uye akatonhodzwa kusvika pa30℃ kuti agadzire crystallization. Mushure mekupatsanurwa, chigadzirwa chapera chinoomeswa pa50~55℃, uye doro remumvura rinodzoserwa kutangi rekusabvisa tsvina. Magnesium sulfate heptahydrate inogonawo kugadzirwa nekusabvisa sulfuric acid ine 65% magnesia mumomorrhea kuburikidza nekusefa, precipitation, concentration, crystallization, centrifugal separation uye dryness, inogadzirwa nemagnesium sulfate.

Equation yemakemikari ekuita: MgO+H2SO4+6H2O→MgSO4·7H2O.

Matanho ekuchengetedza mafambiro:Kurongedza kunofanira kunge kwakazara pakutakura, uye mutoro unofanira kunge wakachengeteka. Pakutakura, iva nechokwadi chekuti mudziyo haufanirwe kudonhedza mvura, kuputsika, kudonha, kana kukuvara. Zvinorambidzwa zvachose kusanganisa neacids nemakemikari anodyiwa. Pakutakura, kunofanira kudzivirirwa kubva kuzuva, mvura uye kupisa kwakanyanya. Mota inofanira kucheneswa zvakanaka mushure mekutakura.

Matanho ekudzivirira mashandiro:Kushanda kwakavharwa uye kusimbisa mhepo inofefetera. Mushandi anofanira kunyatsotevedzera maitiro ekushanda mushure mekudzidziswa kwakakosha. Zvinokurudzirwa kuti vashandi vapfeke mamasiki eguruva ekuzvisvira, magirazi ekuchengetedza emakemikari, kupfeka mbatya dzebasa dzinodzivirira chepfu, uye magirovhosi erabha. Dzivisa guruva. ​​Dzivisa kusangana neacids. Rerutsa uye bvisa paki zvishoma kuti paki isakuvara. Yakashongedzerwa nemidziyo yekurapa yekukurumidzira inodonha. Midziyo isina chinhu inogona kuva netsvina inokuvadza. Kana huwandu hweguruva mumhepo hukadarika mwero, tinofanira kupfeka mask yeguruva yekuzvisvira. Kana paine kununurwa kana kubuda mumhepo, kupfeka mask dzekurwisa hutachiona kunofanira kupfekwa.

Zvidziviriro zvekuchengetedza:Chengeta munzvimbo inotonhorera, ine mhepo inofefetera. Usapinda mumoto nekupisa. Chengeta kure neasidhi uye usashandise zvinhu zvakasiyana-siyana. Nzvimbo yekuchengetera inofanira kunge yakashongedzwa nezvinhu zvakakodzera kudzivirira kubuda kwemvura.
